EPS flame-retardant thermal-insulation wall board
An EPS flame-retardant thermal-insulation wall board belongs to the technical field of building materials and is prepared from polystyrene, melamine, formaldehyde aqueous solution, graphene powder, pullulan, magnesium sulfate solution, barium stearate, magnesium oxide, talcum powder, antioxidant and the like. The preparation method comprises the following steps: firstly, blending polystyrene, graphene powder and a magnesium sulfate solution, uniformly stirring, extruding and granulating to obtain graphene EPS master batch; mixing, heating and stirring a formaldehyde aqueous solution and melamine for reaction, and cooling to obtain melamine formaldehyde resin; then blending the graphene EPS master batch, melamine formaldehyde resin, pullulan, barium stearate, magnesium oxide, talcum powderand an antioxidant, uniformly stirring and mixing, and carrying out injection molding and hot press molding to obtain the EPS flame-retardant thermal-insulation wall board. The EPS wall board has thebeneficial effects that the excellent flame retardant property of the melamine formaldehyde resin and the high oxygen barrier property of the pullulan are utilized to synergistically improve the flameretardant property of the EPS wall board.
一种EPS阻燃保温墙体板，属于建筑材料技术领域，由聚苯乙烯、三聚氰胺、甲醛水溶液、石墨烯粉末、普鲁兰多糖、硫酸镁溶液、硬脂酸钡、氧化镁、滑石粉、抗氧剂等材料制备得到；其制备方法是首先将聚苯乙烯、石墨烯粉末和硫酸镁溶液进行共混，搅拌均匀挤出造粒，得到石墨烯EPS母粒；再将甲醛水溶液和三聚氰胺混合加热搅拌反应，冷却后得到三聚氰胺甲醛树脂；然后将石墨烯EPS母粒、三聚氰胺甲醛树脂、普鲁兰多糖、硬脂酸钡、氧化镁、滑石粉和抗氧剂进行共混，搅拌混匀，注模热压成型后得到EPS阻燃保温墙体板；其有益效果利用三聚氰胺甲醛树脂的优异阻燃性能和普鲁兰多糖的高隔氧性，协同提高EPS墙体板的阻燃性能。
