Magnesium oxide ecological fireproof board and producing method thereof

Abstract

The invention discloses a magnesia bionomic fire proof plate that can shorten maintenance period and improve the water proof and halogenide-resistant performance thereof, which comprises a magnesia core board and surface layers that are made of materials such as non-woven fabrics, glass fiber reticulum, etc. and cover the upper and lower surfaces of the magnesia core board, wherein, the magnesia core board is made by the following materials by weight percentage that: 40-45 percent of magnesia, 10-22 percent of magnesium chloride, 8-15 percent of wood flour, 8-15 percent of perlite, 0.001-1 percent of colophony, 0.001-1 percent of sodium hydroxide, 0.005-1.5 percent of bone glue pearl and 0-8 percent of flavoring essence, and others are water and impurities. The magnesia bionomic fire proof plate of the invention not only has the advantages of being fire proof, being moth proof, corrosion resistance and high strength and light weight, but also needs not sunning and pickling, shortens production period and saves time and cost, solves the defect of being easy to halogenated and humidified and releases light scent.

Description

technical field [0001] The invention relates to a building decoration plate and a production method thereof, in particular to a magnesium oxide ecological fireproof board and a production method thereof. Background technique [0002] At present, the glass magnesium ecological fireproof board (also known as magnesium oxide ecological fireproof board) used for architectural decoration is made of magnesium oxychloride cement (also called magnesite cement) and some modifiers. The traditional processing process includes batching, stirring and mixing, pressing and molding, curing, demoulding, drying, cutting, packaging and other processes. In these processes, it still needs about 7 days of natural drying and curing after demoulding (heating and curing will make the whiteness of the board poor), which makes the cycle of the curing process longer and the site use efficiency is very low (commonly known as occupying) Site), if it encounters rainy weather, the maintenance period will ...

Problems solved by technology

In these processes, it still needs about 7 days of natural drying and curing after demoulding and molding (heating and curing will make the whiteness of the board poor), which makes the cycle of the curing process longer and the site use efficiency is very low (commonly known as occupying Site), if it encounters rainy weather, the maintenance period will be extended accordingly; and the fireproof board produced by traditional technology is easy to be damp and brine, and the whiteness is not good
