Abstract
The invention relates to a preparation method of a composite floor, in particular to a floor for a high-speed train, and belongs to the field of composite floor. The composite floor has a layered structure, and can be divided into five layers. A middle layer is a structure layer composed of an expanded vermiculite fireproof insulation board; the upper and lower layers of the structure layer are reinforced layers composed of stainless steel wire crimped mesh; fiber cement pressure plates are arranged outside the reinforced layers; and the surface of one fiber cement pressure plate is bonded with a rubber floor cloth. The structure layer of the floor adopts the light expanded vermiculite fireproof insulation board, which has fire resistance capacity at more than 1100 DEG C, fire performance reaching level A1, and is smoke-free and non-toxic during high temperature burning. The floor for high-speed train not only gains greatly improved fire retardant effect, and but also has the effects of heat insulation and sound insulation, especially reduced overall weight.
Description
Technical field
The present invention relates to a kind of preparation method of composite floor board, particularly a kind of bullet train, with floor, belongs to composite floor board field.
Background technology
At present, speed per hour reaches bullet train more than 200km/h, and what floor adopted is wooden flame-retardant plywood, and it is made up of surface layer and core.Surface layer is white birch wood and cork combination layer pressing plate, and core is puigging.Its shortcoming is: though floor is through special fire prevention processing, be wood materials after all, when fire occurs, will soon burn.Owing to having added a large amount of fire retardants, flame-retardant plywood can discharge CO, HCN, NO while burning
2deng toxic gas, very large to harm.Glued board use adhesive be Lauxite, in adhesive, the formaldehyde of unreacted formaldehyde or not corresponding formation methylene, remains in flaggy, glued board deposit with use procedure in, free formaldehyde can constantly diffuse out.Glued board proportion is larger, is unfavorable for the speed-raising of vehicle, and the noise producing for vehicle and vibrations do not have good soundproof effect.
Summary of the invention
The object of the invention is the problems referred to above that exist with floor in order to solve existing bullet train, provide a kind of bullet train with floor, this floor is that a kind of light weight, fire prevention, bullet train heat insulation, nontoxic, that soundproof effect is good are used floor.
The object of the invention is to be achieved through the following technical solutions.
A kind of bullet train is used floor, and this composite floor board is layer structure, can be divided into five layers.Intermediate layer is the structure sheaf being made up of expanded vermiculite fireproof heated board; The upper and lower faces of this structure sheaf is the enhancement layer being made up of stainless steel wire crimped wire mesh; Enhancement layer is outward fiber cement board pressure; The surface binded of the one deck in two-layer fiber cement board pressure has rubber floor covering cloth; Between each composite bed, be fixedly connected with by adhesive;
The both sides of described floor main body are arranged with tenon or groove, fixing while being convenient to floor splicing.
Described expanded vermiculite fireproof heated board comprises that weight ratio is 50%～70% expanded vermiculite small powder (particle diameter 1～3mm), 30%～50% inorganic adhesive, 2%～3% curing agent, 1.5%～2.5% waterproofing agent.
The preparation method of described expanded vermiculite fireproof heated board, concrete steps are as follows:
1) expanded vermiculite small powder is fed intake in blender, then curing agent is sprinkling upon on expanded vermiculite small powder equably, stir; Open glue spraying valve, spray while stirring inorganic adhesive, after glue spraying, continue to stir;
2) mould is prepared, to the guide rail setting in advance, load onto locator bar.At the bottom of mould, the smooth plastic plate of pad upper surface, and on plastic plate, brush one deck releasing agent.The material having stirred is poured in mould, struck off by hand, surface repaves one deck and has brushed the plastic plate of releasing agent.
3) mould is pushed in hydraulic press zone of heating along guide rail, adjust mould in press centre, then rising press, till making pressure reach 12MPa.After press pressure is stable, stop, remain on 145～150 DEG C of heating under this pressure condition.
4) loose pressure machine, ejection die, will slightly press vermiculite board in press, to carry out heating curing after moving back mould.The complete vermiculite board of maintenance is steadily released, and throws off plastic plate in the time being slowly down to normal temperature, and vermiculite board is carried out to sanding, and size in accordance with regulations cuts.
Described rubber floor covering cloth is the floor cloth that the bullet trains such as domestic EMUs and subway use.
Described adhesive is organic siliconresin class adhesive, the organic siliconresin class adhesive that the bonding of the bonding between all sheet material and rubber floor covering cloth is all used.
Beneficial effect
