Description
Technical field
The present invention relates to a kind of environment-friendly type fire-proof coating for tunnels, specifically a kind of environment-friendly colored fire-proof coating for tunnels that can be used for the different colours requirement.
Background technology
Along with high speed development of national economy, urban construction is accelerated, and the floating population increases sharply, and transport development reaches to improve and seems particularly important.And the tunnel is realized that target range is the shortest, floor space is minimum, physical environment and landscape destruction degree minimum, characteristics that cost is low has been subjected to planning construction person's favor with it.But tunnel structure generally is to be assembled by stone and Steel Concrete to form, and when temperature rose to 600 ℃, concrete strength was with a toll of more than 50%, and the yielding stress of steel drops under the normal temperature force-at-yield below 1/3.And during the tunnel presence of fire, temperature is generally more than 1000 ℃, the tunnel masonry is difficult to bear high temperature like this, serious part burns down easily, and it is airtight relatively to add tunnel environment, and people's flow density is big, in case presence of fire, the evacuation and the quite difficulty of putting out a fire to save life and property cause great loss of life and personal injury and property damage easily, and therefore the tunnel being prevented fires from handling seems very important.
Fire-proof coating for tunnels is just progressively to study and produce from late 1990s, mainly is made up of binding agent, inorganic fire resistant infilling, fire retardant and auxiliary agent.Its flameproof protection principle is: fire-resistantly do not fire by self, at high temperature form adamantine membrane sealing base material, secluding air, intercept flame and heat, thereby reach the purpose of fire protection flame retarding.Therefore fire-proof coating for tunnels is the fire endurance that improves the tunnel, prevents that the steel member from because of heating up rapidly one of effective safeguard procedures of deformation slump taking place in fire.Because the length in tunnel is different with design requirements, also more and more higher to the decoration requirement of inner surface of tunnel, present way is external coating or spraying finishing fire retardant paint or the Decorative Cover finish paint that arrives at fire-proof coating for tunnels.These finish paints are organism mostly, and cost is higher, discharge toxic gas in high temperature or fire easily, quicken flame transmission; And the easy variable color of organic coating, weather resisteant is poor.
Summary of the invention
At the defective of present fire-proof coating for tunnels, the invention provides different colours, fire endurance height and moderate environment-friendly colored fire-proof coating for tunnels.
Environment-friendly colored fire-proof coating for tunnels of the present invention comprises the content of following component and mass fraction:
Component 1: 10～50 parts of cement
Component 2: 40～90 parts of pearlstone, expanded vermiculite and light calcium carbonates
Component 3: 1～10 part of inorganic mineral fiber
Component 4: 5～30 parts of flame-retardant systems
Component 5: 0.1～5.0 part of rubber powder
Component 6: 0.5～3.0 part of water reducer, air entrapment agent and swelling agent
Component 7: 0.5～2.0 part of mineral dye.
Mix through the forced action type mixer and to get final product.
Described cement is ordinary Portland cement or quick hardening sulphoaluminate cement, and its strength mark is not less than 42.5; Flame-retardant system employing magnesium hydroxide and aluminium hydroxide are composite; Water reducer is poly carboxylic acid or naphthalene series high-efficiency water-reducing agent; Air entrapment agent is rosin based or alkylsulfonate system.
The mechanism of action of the present invention is: with ordinary Portland cement or high-alumina cement is jointing compound, with the gluing of various lightweight weighting agent together, adds fire retardant and various auxiliary agent simultaneously therein; The lightweight weighting agent can effectively reduce thermal conduction because transmissibility factor is less.Flame-retardant system can reduce the temperature of fire-proof coating for tunnels in fire, effectively protects base material.Water reducer, rubber powder then play remarkable improve workability, application property, close-burning effect.Mineral dye can be given the fire-proof coating for tunnels distinct colors.
During construction, the material that the present invention is prepared adds the water of (mass percent 1: 0.8～1: 1.5), adopts forced mixer to mix and stir into wet mortar, takes the mode of conventional spraying, sprays to treated structures surface and gets final product.When closing on initial set, optical processing is received on the surface.
Innovative point of the present invention and beneficial effect are: (1) adds mineral dye in fire-proof coating for tunnels, can satisfy the demand of different color and daylighting, can reduce the cost that tunnel surface is decorated.(2) simplify construction technology, reduced the operational procedure of finishing paint.(3) have characteristics such as fire endurance, cohesive strength height, water-tolerant, this fire-proof coating for tunnels does not produce any toxic gas and waste in construction process and the fire, safety and environmental protection.(4) this coating can be widely used in the flameproof protection of highway, railway, subway tunnel construction, also can be used for the fireproof brickwork of petrochemical industry project etc.
