Abstract

The invention relates to a board, in particular to a multi-use composite reinforcing board and a production process thereof. The multi-use composite reinforcing board comprises a surface slurry layer, a glass fiber cloth layer, a main body material layer, a glass fiber cloth layer, a framework material layer, a main body material layer, a glass fiber cloth layer and a non-woven fabric layer from top to bottom in turn. The production process comprises the following steps: preparing a MgCl2 solution; stirring surface slurry and main body slurry; sending a template; scraping the surface slurry; laying glass fiber cloth; scraping the main body slurry; laying the glass fiber cloth; laying framework materials; scraping the main body slurry; laying the glass fiber cloth; and laying non-woven fabrics. The composite board has the advantages of fire resistance, water resistance, insect prevention, light weight, compression resistance, bending resistance, high strength, no growth of green moss, and the like. The multi-use composite reinforcing board does not contain formaldehyde and benzene, accords with the environmental protection requirement, and can be used in floor plates, floor, various tabletop plates, templates, trays, flitch, upright posts and the like.

Description

technical field [0001] The invention relates to a board, in particular to a multi-purpose composite reinforced board and its production process. Background technique [0002] Existing plank is of a great variety, mainly contains original plank, plastic board, cement fiberboard etc., but all has its own shortcoming. The original board is not fireproof, prone to insects, and easy to corrode. Plastic boards are not fireproof, easy to deform, and easy to age. Cement fiberboard is heavy, easy to break, and difficult to construct. It has been more than 120 years since the Frenchman Sorel invented magnesia cement in 1867. Its products have good fire resistance, low thermal conductivity, and high compressive and flexural strength. Glass magnesium board (GM-Siding) is derived from magnesia cement and is a kind of magnesia cementitious material. Its main structure is magnesium oxide (MgO), magnesium chloride (MgCl 2 ) and water (H 2 O) ternary system with reinforcing materials. ...
