And the realization of the tunnel to target range shortest, covers an area of at least, on the natural environment and landscape minimum damage degree, low cost of characteristic was planning builder's favor. But the tunnel structure is commonly by rocks and reinforced concrete LeiQi and become, the temperature rise to 60 0 ℃, concrete strength loss of 50 % above, steel yield stress to room temperature yield force 1/3 below. And tunnel when there is a fire, the average temperature in 1 00 0 ℃ above, tunnel masonry unbearable such heat, serious parts easy burn collapse, plus tunnel surroundings relative airtight, flow density, once the fire evacuation and saves quite difficult and easy to cause the heavy casualties and property losses, therefore for tunnels for fire prevention is very important.　　《 2005 年中国公路水路交通行业发展统计公报》显示，截止 2005 年底，全国已建成公路隧道 2 889 处，共 152.7m ；其中采用阻燃设计约占 1/10 ，因此对已有隧道防火改性具有较大的市场空间。同时据第三届铁路隧道年会发布的消息，今后 6 年我国将新建 300 万 m 长的铁路隧道，并且随着北京到上海高铁项目的立项，必将带动隧道相关产品的需求量，特别是隧道防火涂料的需求量。　　The "2005 China highway waterway transportation industry development statistical bulletin" shows that by the end of 2005, national highway tunnel 2 889 already built in 152.7 m, altogether, Which USES anti-burns the design accounted for about 1/10, so the existing tunnel fire modified with larger market space. At the same time according to the 3rd railway tunnel conference news releases, for the next six years in China would be built 300 million m long railway tunnel, and along with the Beijing to Shanghai high iron project project, will surely promote tunnel related products demand, especially tunnel fire retardant coating demand.1 隧道防火涂料的组成1 the composition of tunnel fire coatings隧道防火涂料主要由粘结剂、耐火填料、发泡材料和助剂组成。Tunnel fire coatings consists mainly of binder, refractory fillers, foaming material and additive composition.(1) 粘接剂：约占涂料总体积的 35 ％～ 40 ％。苯丙、醋丙、 EVA 、 582 树脂、水玻璃、耐火水泥、磷酸盐等均为较好的粘结剂。由于粘结剂的用量较多，选择粘结剂时，需考虑材料的价格、燃烧性能及火灾时的烟气情况。(1) adhesive: accounted for about of the total volume coating 35% ～ 40%. Styrene-acrylic, vinegar c, EVA, 582 resin, sodium silicate, refractory cement, phosphate, etc. For better binder. Because binder amount more, choose binder, need to consider material price, combustion performance and fire smoke.(2) 耐火填料：是隧道防火涂料的骨架成分之一，约占涂料总体积的 35 ％～ 38 ％，其主要作用是高温隔热和降低热导率。海泡石、膨胀珍珠岩、轻质碳酸钙、玻璃空心漂珠、高岭土、矿渣棉、超细硅酸铝等均是良好的无机轻质隔热填料。(2) refractory packing: is tunnel fire coatings skeleton of the component of total volume, accounting for approximately coating to 35%～ 38%, its main effect is heat insulation and reducing thermal conductivity. Sepiolite, expanded perlite, light calcium carbonate, glass hollow drift beads, kaolin, slag cotton, superfine guisuanlu:, etc. Good inorganic lightweight heat insulation packing.(3) 膨胀剂：是隧道防火涂料的另一个主要成分，约占涂料总体积的 8% ～ 10% 。高温时，涂料成分发生改变，膨胀剂迅速发生膨胀，从而形成多孔的隔热层，阻止热量向隧道砌体的传递。膨胀蛭石、重铬酸铵为无机发泡材料；三聚氰胺、季戊四醇、聚磷酸铵是成熟的有机发泡体系，多在薄型或超薄型防火涂料中使用。(3) expander: tunnel fire coatings is another major ingredients, accounting for approximately coating total volume of 8% and 10%. High temperature, coating composition change, expansive agent happen quickly, thus forming porous expansion of insulating layer, prevent heat to the tunnel masonry relay. Expanded vermiculite, potessium dichromate ammonium for inorganic foaming material, Melamine, pentaerythritol, poly LinSuanAn is ripe organic foam system, more in the thin or super-thin fire-retardant coating in use.(4) 阻燃剂：用于涂料的阻燃，约占涂料总体积的 12% ～ 15% 。它受热时吸热失水，协助膨胀隔热。一般选用结晶水较多的硼化物、锌化物及氢氧化铝、氢氧化镁。(4)used for flame retardant coating of flame retardant coatings, accounts for about cent of the total volume 12% ～ 15%. It when heated heat-sink dehydrate, assist expansion heat insulation. Generally choose gesso more boron hydrates, zinc carbide and aluminum hydroxide, magnesium hydroxide.(5) 其他助剂：主要改善涂料的和易性及理化性能，约占涂料总体积的 3% ～ 5% 。常用的助剂有可再分散胶乳、高效减水剂等。(5) other additives: mainly improve coating the workability and physical-chemical properties of the coating, accounting for approximately of the total volume 3% ～ 5%. Common fertilizer have redispersible latex, efficient jianshuiji, etc.2 现今隧道防火涂料的缺陷2now tunnel fire coatings defects　　我国对隧道结构进行防火保护工作始于 20 世纪 80 年代中期，但限于当时的技术、经济状况，除了上海延安东路越江隧道等有限的几个隧道喷涂了防火涂料外，其它隧道的结构都没有采取防火措施。真正根据有关隧道设计规范设计、建造隧道，还是近几年的事，而隧道防火涂料的应用，则是从 2001 年前后开始的，当时一些企业将厚型钢结构防火涂料或混凝土楼板防火涂料甚至电缆防火涂料作为隧道防火涂料使用。因此关于隧道防火涂料研究的基础比较薄弱，产品参差不齐，给隧道防火涂料施工和性能检测带来很大困难。现今国内隧道防火的主要缺陷有以下几点：　　Our country of tunnel structure of fire protection work in the 20th century began in the 1980s, but limitation of the technology at that time, economic status, except Shanghai yanan east roas tunnel etc limited several tunnel spraying the fireproofing outside, other tunnel structure are not adopt fire prevention measures. True according to the relevant tunnel design code design, build the tunnel, or in recent years, and the application of tunnel fire coatings, is from 2001, when beginning around some enterprises will thick steel structure fire-retardant coating or concrete floor fireproofing even cable fire coatings as tunnel fire coatings used. So about tunnel fire coatings research foundation was weak, the product is uneven, for tunnel construction and performance testing fireproofing enormous difficulties. Current domestic tunnel fire main defects have the following:(1) 涂层太厚。如按 ISO 834 曲线升温，耐火性能达到 3h ，一般涂料涂层厚度约需 20 ～ 30 mm ；由于涂层较厚，需要多次喷涂，施工困难。如按碳氢曲线升温，隧道防火涂料不能承受快速升温的热冲击，可能在几分钟内就发生爆裂，不能满足隧道的特殊防火要求。(1) coating is too thick. E.g. by ISO 834 curve thawing, fireproof performance reach 3h, general coating thickness need about 20 ～ 30 mm, Due to the coating thicker, requiring multiple coating, construction difficulties. If press hydrocarbon curve thawing, tunnel fire-retardant coating cannot bear the rapid increase of thermal shock, possibly in a few minutes to burst, cannot satisfy the special requirement of fire tunnel.(2) 粘结强度低。隧道防火涂料的粘结强度一般为 0.1MPa ，车辆在隧道通行时，会产生强风和震动，不能满足隧道的实际需要。(2) bond strength low. Tunnel fire retardant coating adhesive strength general 0.1 MPa, the vehicles on tunnel passes, they produce winds and vibration, cannot satisfy the tunnel practical needs.(3) 未注重涂层毒性研究，一旦发生火灾，将影响火灾的扑救和隧道的修复。(3) did not notice coating toxicity study, once the fire will affect the fire fighting and tunnel repair.(4) 耐水性较差，涂层长期处于隧道的潮湿环境中，会积水、甚至脱落。(4) water resistance is poorer, coating in the long run, tunnel in damp environment, water, or even fall off.3 隧道防火涂料的设计原则3 tunnel fire retardant coating design principles　　国内外就隧道防火涂料研究已开展了大量的工作。如国内学者提出一种以硅酸盐为主要粘结剂，以氢氧化铝、膨胀蛭石、三硅酸镁等为填充料，四硼酸钠为防火助剂的隧道防火涂料；针对隧道砌体不耐高温的特点，研制了一种以无机胶凝材料为主的耐潮湿环境的水硬性隧道防火涂料，该涂料可同时应用于钢结构和混凝土的防火保护；开发了一种新型的物理膨胀阻燃剂，以可膨胀石墨为主，制取了一种无卤、环保、并具有优良防火性能的物理膨胀型防火涂料。　　Both at home and abroad is fire-retardant coating research have already undertaken tunnel is a lot of work. If domestic scholars put forward a kind of silicate as main bond, aluminum hydroxide, expanded vermiculite, three magnesium silicate as tower.it boric acid sodium, four for fire prevention auxiliaries tunnel fire coatings, For tunnel masonry not high temperature resistant characteristics, and developed a kind of based on inorganic cementitious materials mainly of the hydraulic resistance to damp environment fire-retardant coating, the coating tunnel can simultaneously steel structure and concrete application of fire protection; Developed a new type of physical expansion flame retardants, by expansible graphite is given priority to, making a halogen-free, environmental protection, and has good fireproof performance of physical expandable fire-retardant coating.　　而国外学者研制出建筑物表面的无机防火涂料，由水硬性白水泥、水玻璃、蛭石、膨胀珍珠岩、无机玻璃纤维等组成；推出了以海泡石、钙硅石、增强纤维、高铝水泥、无定型硅石为主要组成的防火涂料，该涂料具有很好的绝热性和防爆裂性，可应用于建筑物外墙、隧道等；可用于金属和混凝土表面的防火涂料，由膨润土、硅酸铝、硅灰石、硅酸镁、玻璃微珠及一些多孔填料组成，粘结剂为水玻璃、波特兰水泥、石膏、磷酸盐类中的一种或几种等。　　And foreign scholars developed building surface of inorganic fireproofing, by water rigid white cement, sodium silicate, vermiculite, expanded perlite, inorganic glass fiber etc; Launched by sepiolite, calcium silex, enhance fiber, high aluminium cement, no finalize the design for the main composition of silica fire-retardant coating, the coating has very good insulation sex and preventing burst, can be applied to building facades, tunnels. Can be used in metal and the concrete surface fireproofing, by bentonite, silicate wollastonite, aluminum, magnesium silicate, glass beads and some porous filler composition, binder for sodium silicate, Portland cement, gypsum, phosphate classes are in one or several etc.　　上述报道的隧道防火涂料制造均是以水玻璃、水泥、白水泥、高铝水泥、磷酸盐类等无机物为粘结料，以珍珠岩、膨胀蛭石、微空硅酸钙、硅藻土、粉煤灰玻璃微珠、海泡石粉、滑石粉等为填充骨料，以玻璃纤维、钢纤维、聚丙烯纤维等为增强材料，以含结晶水的铝、镁、硼、锌的氧化物等为阻燃剂，以上产品其组分主要由无机材料构成。而从国内外各类防火涂料的文献专利看出，用于保护不燃性建筑结构的涂料包括有机膨胀型厚浆涂料和轻体无机防火涂料两类。在火灾温度下，有机膨胀涂料的碳质泡沫层，易逐渐消失而降低防火隔热作用，即使是最好的涂料，涂层增至 4 mm 时，耐火极限也只有 1h 。而无机防火涂料，由于密度轻，热导率小，耐火性能好，随涂层厚度不同，可满足 1 ～ 2h 甚至更长时间的耐火要求。但纯无机物构成的防火涂料，容易出现硬而脆、产生龟裂脱落等不利情况。因此，在隧道防火涂料的研究中，一般应采用非膨胀型、无污染的水性有机—无机复合涂料的研究技术路线。　　The reports of the tunnel fire coatings manufacturing all regard the sodium silicate, cement, white cement, high aluminum phosphate cement, such as adhesive materials, with inorganic perlite, expanded vermiculite, micro empty calcium silicate, diatomite, fly ash glass bead, sea bubble cement and talcum powder as the filling aggregate, with glass fiber, steel fiber and polypropylene fiber etc for reinforced materials, with containing gesso of aluminum, magnesium, boron, zinc oxide, such as flame retardant products above its components, mainly by inorganic material composition. From all kinds of domestic and foreign fire-retardant coating of literature that used to protect patent incombustible organic coatings include building structure of expandable hi-build paint and light body inorganic fireproofing two kinds. The fire temperature, the organic expansion of coating carbonaceous foam layer, easy fades reducing fire adiabatic effect, even the best coating, coating increased to 4 mm, refractory limit only 1h. And inorganic fire-retardant coating, because light density and thermal conductivity small, refractory coating thickness, good performance with different, can meet 1～ 2h even longer refractory requirements. But the pure inorganic composition of fireproofing, is easy to appear the hard and crispy, cracks off such negative situation. Therefore, in tunnel fire coatings study, should be generally using an expandable and pollution-free water based organic inorganic compound coating -- research technical route.
