Environment-friendly magnesium oxide board added with waste as filler and preparation method thereof
The invention discloses an environment-friendly magnesium oxide board added with waste as filler. The environment-friendly magnesium oxide board is characterized by being prepared from the following raw materials in parts by weight: 5-7 parts of tourmaline powder, 0.2-0.24 part of silane coupling agent kh550, 1.5-2 parts of waterborne polyurethane, 6-8 parts of 5% polyvinyl alcohol solution, 42-45 parts of light calcined magnesia, 40-42 parts of magnesium chloride hexahydrate, 10-12 parts of corn stalk, 4.5-5 parts of metakaolin, 2.5-3 parts of aluminium dihydrogen phosphate, 3-4 parts of fly ash, 4-6 parts of styrene-butadiene latex, 15-18 parts of thermoplastic phenolic resin, 5-6 parts of 25% urotropin aqueous solution, 1.5-2.5 parts of aluminum silicate fiber and appropriate pure water. According to the preparation method disclosed by the invention, the surface of the moulded board is coated with a layer of phenolic resin, and the aluminum silicate fiber contained in the phenolic resin has effects of preventing water and corrosion and retarding flame so as to reduce erosion of the board caused by external environment; and meanwhile, the quality problems such as moisture absorption scumming, buckling deformation and product cracking are solved.
