Double-layer composite glass magnesium board with high fireproof grade and preparation method of double-layer composite glass magnesium board
The invention discloses a double-layer composite glass magnesium board with a high fireproof grade. The double-layer composite glass magnesium board is characterized by being prepared from the following raw materials in parts by weight: 42-45 parts of light calcined magnesia, 39-41 parts of magnesium chloride hexahydrate, 7-9 parts of forsterite powder, 5-7 parts of tourmaline powder, 4-6 parts of expanded graphite, 1-2 parts of ammonium polyphosphate, 4.5-5 parts of metakaolin, 2.5-3 parts of aluminum dihydrogen phosphate, 1.5-2.5 parts of aluminum silicate fibers, 0.2-0.25 part of a silane coupling agent kh 550, 1.5-2 parts of waterborne polyurethane, 6-8 parts of a 5% polyvinyl alcohol solution, 15-18 parts of thermoplastic phenolic resin, 5-6 parts of 25% urotropine aqueous solution and a proper amount of pure water. According to the double-layer composite glass magnesium board, the forming time is shortened through a modifying process, the process is convenient for industrial control, the components are simple and easily available, and the production efficiency is improved; the prepared glass magnesium board has double-layer effect, is smooth and attractive in surface, high in fireproof grade, safe and non-toxic, and a moisture absorption and deformation problems are solved.
