Problems solved by technology

[0005] General calcium silicate boards have the functions of flame retardant, fire prevention, moisture resistance and impermeability, and can play their role in normal engineering environments; but for high humidity, underground, tunnels, easy to mold, high fire protection requirements and crowded public buildings Places and other environments, due to harsh environmental factors, the calcium silicate board loses or partially loses its moisture-proof and fire-proof properties in a short period of time, and is prone to mildew, which greatly reduces the performance and service life of the calcium silicate board.

Abstract

The invention relates to a damp-proof anti-firing plate, comprising the following raw material by weight parts: EPS microcrystalline powder 47-57 weight parts, cellulose reinforced fiber 175-186 weight parts, wollastonite powder 45-55 weight parts; quartz powder 395-405 weight parts; lime powder 95-105 weight parts; Portland cement 195-205 weight parts; water 3501-3511 weight parts; poly-propenyl alcohol 16-26 weight parts. The preparation method of the damp-proof anti-firing plate comprises the following steps: debending fiber; stirring basis material; mixing the basis material with the debended fiber; beater-forming; steam-pressure maintaining; water seal-treating. The formula of the invention and the steam-pressure maintaining method make the hydration reaction generate more intact calcium silicate board and more calcium pectolite crystal and the anti-firing performance is increased with anti-molding performance and good moisture resistance under damp bad environment.

Description

technical field [0001] The invention relates to a moisture-proof and fireproof board and a preparation method thereof. Background technique [0002] The most commonly used moisture-proof fireproof board is calcium silicate board, which was first successfully developed in the United States in the 1940s, and was popularized and applied on ships from the late 1940s to the early 1950s. In the early 1950s, the United Kingdom, Japan and other countries successively introduced the production technology of calcium silicate board from the United States, which enabled the rapid development of this product, while China began to produce calcium silicate board in the late 1980s. [0003] Calcium silicate board is a new type of building material with the characteristics of light weight, high strength, flame retardant and fire resistance, moisture resistance and impermeability, can be planed, sawed and nailed, excellent weather resistance, and not afraid of insects, and has stable performa...
