Abstract
The invention discloses a fire retardant coating for tunnels. The fire retardant coating comprises the following raw materials in part by weight: 20-23 parts of aluminium tripolyphosphate, 21-23 parts of water glass, 10-12 parts of expanded perlite, 7-10 parts of mica powder, 7-9 parts of aluminium silicate fiber, 30-35 parts of magnesium hydroxide, 15-18 parts of polyvinyl acetate emulsion, 13-15 parts of Portland cement, 18-20 parts of sepiolite, 35-40 parts of ammonium dichromate, 1.5-2 parts of 528 resin, and 3-3.5 parts of cellulose ether. The fire retardant coating has good fire resistance, high bonding strength and stable physical and chemical properties, as well as water resistance and corrosion resistance.
Description
Technical field
The present invention relates to coating preparation field, be specifically related to a kind of fire-proof coating for tunnels.
Background technology
Tunnel is buildings common in modern public transport engineering.And along with traffic engineering construction scale increasing, tunnel number get more and more, tunnel mileage is more and more longer, and tunnel structure is relatively airtight, traffic flow is large, once presence of fire in tunnel, fire extinguishing is difficulty quite, therefore, improves tunnel fire proofing ability very important.At tunnel construction thing surface spraying frie retardant coating, heat energy when stoping fire to occur directly imports tunnel construction thing surface into, and extend the tunnel construction thing heating-up time, winning spray meeting to fire-fighting, is one of important measures making tunnel avoid being damaged.
Summary of the invention
Technical problem to be solved by this invention is, overcomes the shortcoming of prior art, provides a kind of preparatory technology simple fire-proof coating for tunnels, and the present invention has that fire-resistant fire resistance is good, bonding strength is large, physicochemical property is stable, has water tolerance and erosion resistance simultaneously.
In order to solve above technical problem, the invention provides a kind of fire-proof coating for tunnels, it is made up of the raw material of following weight part: aluminium triphosphate 20-23, water glass 21-23, pearlstone 10-12, mica powder 7-10, aluminum silicate fiber 7-9, magnesium hydroxide 30-35, poly-cerinic acid vinyl acetate emulsion 15-18, silicate cement 13-15, sepiolite 18-20, ammonium dichromate 35-40,528 resin 1.5-2, ether of cellulose 3-3.5.
The beneficial effect that technical scheme provided by the invention is brought is: a kind of fire-proof coating for tunnels, and this coating has that fire-resistant fire resistance is good, bonding strength is large, physicochemical property is stable, has water tolerance and erosion resistance simultaneously.
