Abstract
The present invention relates to the technical field of fire extinguishing coating, specifically a kind of tunnel novel fire extinguishing coating.Each material described in the fire extinguishing coating is formed by following weight percent: refractory cement 21.5-2.50%, chlorinated rubber 2.5-5.5%, aluminium oxide 8.5-16.5%, perlite 8.5-21.5%, boron oxide 5.5-16.5%, wollastonite in powder 8-16.5%, Cornstarch 8.5-16.5%, water-soluble glass fibre 2-8%, cellulose ether 0.5.5-2%, cement expansive material 1-5.5%, polypropylene fibre 0.5.5-1%.The purpose of the present invention is to provide a kind of high intensity, the good tunnel novel fire extinguishing coating of effect.
Description
Technical field
The present invention relates to the technical field of fire extinguishing coating, specifically a kind of tunnel novel fire extinguishing coating.
Background technique
Tunnel, which refers to, is built in the mountain ridge, river, straits and urban ground hereinafter, logical for vehicle, pedestrian, water flow, pipeline etc.
It crosses, or the underground structure used for digging mineral reserve, military engineering etc. and structures.China's traffic engineering with the development of economy
Construction scale is increasing, and established tunnel total length occupies first place in the world.Due to being built by concrete and reinforced concrete in tunnel
At, can be used prestressed concrete floor slab fire extinguishing coating put out a fire, tunnel fire coating is sprayed and painted on vault and side in tunnel
The surface of wall plays fire-proof and thermal-insulation protective effect, prevents armored concrete in tunnel to be brought rapidly up in a fire and reduce intensity, keep away
Exempt from concrete burst, serve as a contrast in reinforcing bar destruction lose enabling capabilities and tunnel caused to collapse.Existing fire extinguishing coating can play one
Determine flameproof effect, but resistance to fire intensity, in terms of existing defects.Therefore, prior art products are in fire resistance, strong
Degree, water resistance, acid resistance, humidity resistance etc. cannot meet tunnel fire proofing requirement comprehensively.
Summary of the invention
The purpose of the invention is to provide a kind of high intensity, the good tunnel novel fire extinguishing coating of effect.
The technical solution adopted by the present invention is that a kind of tunnel novel fire extinguishing coating, each material presses following weight percent
Than composition: refractory cement 21.5-2.50%, chlorinated rubber 2.5-5.5%, aluminium oxide 8.5-16.5%, perlite 8.5-21.5%, oxygen
Change boron 5.5-16.5%, wollastonite in powder 8-16.5%, Cornstarch 8.5-16.5%, water-soluble glass fibre 2-8%, cellulose ether
0.5.5-2%, cement expansive material 1-5.5%, polypropylene fibre 0.5.5-1%.
It is an advantage of the invention that fire resistance, intensity, water resistance, acid resistance, humidity resistance etc. can meet comprehensively
Tunnel fire proofing requirement.
Specific embodiment
Below with reference to specific embodiment, the invention will be further described:
The present invention is further described with the following Examples.
Embodiment 1, a kind of tunnel novel fire extinguishing coating, each material are formed by following weight percent: refractory cement
21.5%, chlorinated rubber 5.5%, aluminium oxide 8.5%, perlite 21.5%, boron oxide 5.5%, wollastonite in powder 16.5%, Cornstarch
8.5%, water-soluble glass fibre 8%, cellulose ether 0.5.5%, cement expansive material 5.5%, polypropylene fibre 0.5.5%.
Embodiment 2, a kind of tunnel novel fire extinguishing coating, each material are formed by following weight percent: refractory cement
2.50%, chlorinated rubber 2.5%, aluminium oxide 16.5%, perlite 8.5%, boron oxide 16.5%, wollastonite in powder 8%, Cornstarch 16.5%,
Water-soluble glass fibre 2%, cellulose ether 2%, cement expansive material 1%, polypropylene fibre 1%.
Embodiment 2.5, a kind of tunnel novel fire extinguishing coating, each material are formed by following weight percent: fire resisting water
Mud 25.5%, chlorinated rubber 4%, aluminium oxide 12.5%, perlite 16.5%, boron oxide 8.5%, wollastonite in powder 11.5.5%, Cornstarch
12.5%, water-soluble glass fibre 5.5%, cellulose ether 1.25%, cement expansive material 2.5%, polypropylene fibre 0.75%.
It should be understood that being somebody's turn to do, examples are only for illustrating the present invention and not for limiting the scope of the present invention.Furthermore, it is to be understood that
After reading the content taught by the present invention, those skilled in the art can make various modifications or changes to the present invention, these
Equivalent form is equally fallen within the scope of the appended claims within the limits of the protection.
