Problems solved by technology

Once a fire breaks out in the kitchen, it will cause great casualties and property losses due to the existence of various edible oils and flammable gases. Therefore, fire prevention in the kitchen is a problem that cannot be ignored.
[0003] In order to prevent the occurrence of kitchen fires, kitchen countertops, floors, walls, and ceilings must use Class A fireproof decoration materials. At present, most kitchen countertops and wall panels use fireproof materials such as ceramics, stainless steel, reinforced glass, and paint. None of them can meet the requirements of waterproof, moisture-proof, high temperature resistance, and not easy to be stained with oil at the same time.
Fiber-reinforced calcium silicate board, as a new type of green and environmentally friendly building material, has excellent fire resistance and moisture resistance, and is widely used in commercial engineering and building wall panels. Performance needs to be improved; in order to meet the needs of kitchen countertops and wall panels for plates, we need to improve the production process of fiber-reinforced calcium silicate boards to prepare high-performance carbon fiber-reinforced calcium silicate boards

Abstract

The invention discloses a processing method of a high-performance carbon fiber-reinforced calcium silicate board. The method comprises the following steps of 1 proportioning and pulping, wherein raw materials are separately weighed according to proportions and added into a ball mill, water of which the mass is 5 times that of the raw materials is added, all the materials are ball-milled to be uniform, and a pulp is obtained; 2 blank making, wherein a mold is prepared according to a needed size, and the pulp is injected into the mold for molding; 3 steam curing, wherein the mold injected with the pulp is subjected to an accelerating curing reaction in high temperature and high pressure saturated steam; 4 surface treatment, wherein the surface of the well-prepared fiber-reinforced calcium silicate board is sprayed with a layer of self-cleaning coating before use, and the high-performance carbon fiber-reinforced calcium silicate board is obtained. The processing method of the high-performance carbon fiber-reinforced calcium silicate board has the excellent advantages that the prepared calcium silicate board is fireproof, resistant to moisture, resistant to oil fouling, high in strength and good in tensile property.

Description

technical field [0001] The invention relates to the preparation of a calcium silicate board, in particular to a processing method of a high-performance carbon fiber reinforced calcium silicate board. Background technique [0002] In recent years, with the development of my country's economy, large-scale catering establishments and even family kitchens have been electrified, which increases the risk of fire while achieving convenience and speed. Especially in the kitchen of the catering industry, there are usually liquefied petroleum gas pipelines, diesel, The coexistence of coal stoves can easily cause fires. Once a fire breaks out in the kitchen, it will cause great casualties and property losses due to the existence of various edible oils and flammable gases. Therefore, fire prevention in the kitchen is a problem that cannot be ignored. [0003] In order to prevent the occurrence of kitchen fires, kitchen countertops, floors, walls, and ceilings must use Class A fireproof ...
