Aerogel modified inorganic isolation and partition polystyrene insulation board and preparation method thereof
The invention relates to the technical field of building materials and fireproof thermal insulation materials, in particular to an aerogel modified inorganic isolated and partitioned polystyrene thermal insulation board with the combustion grade capable of reaching the A-grade standard and a preparation method of the aerogel modified inorganic isolated and partitioned polystyrene thermal insulation board. A polystyrene insulation board is used as a base material, the polystyrene insulation board is formed by foaming and compression molding of expandable polystyrene particles, aerogel modified inorganic flame-retardant mixtures are filled among the polystyrene particles, and aerogel modified inorganic isolation and partition structures are formed around insulation particle media. The upper and lower surfaces of the insulation board body are mechanically extruded to form density enhanced areas; low-energy-consumption normal-pressure physical pouring, vacuum auxiliary filling and mechanical enhanced extrusion modes are combined, so that particle gaps of the polystyrene foam board are uniformly filled with the aerogel modified inorganic flame-retardant material, a hard protection layer is formed, continuous combustion of flames is blocked while the strength is improved, and the effect of isolating the external flames is achieved.
本发明涉本发明涉及建筑材料、防火保温材料技术领域，具体涉及一种燃烧等级能达到A级标准的气凝胶改性无机隔离分仓聚苯乙烯保温板及其制备方法；以聚苯乙烯保温板为基材，聚苯乙烯保温板是由可发性聚苯乙烯颗粒发泡模压成型，聚苯乙烯颗粒之间填充有气凝胶改性无机阻燃混合物，在保温颗粒介质周围形成气凝胶改性无机隔离分仓结构，保温板体的上下两面经机械挤压后均形成密度增强区；本发明将低能耗的常压物理浇注、真空辅助填充与机械增强挤压方式相结合，使气凝胶改性无机阻燃材料均匀填充到聚苯乙烯泡沫板的颗粒间隙中，形成一层坚硬的保护层，增加强度的同时阻挡火焰的继续燃烧，起到隔绝外界火焰的作用。
