一种聚苯乙烯颗粒防火保温板及其制备方法
摘要：
本发明公开了一种聚苯乙烯颗粒防火保温板，该保温板由耐碱网格布和防火保温板主材组成；本发明还公开了聚苯乙烯颗粒防火保温板的制备方法，其制备方法为：将增塑剂、苯丙乳液、可分散乳胶粉、天然乳胶、非离子—阴离子混合表面活性剂和MgCl2溶液放入搅拌机中搅拌均匀，然后加入防火剂、增强纤维、聚丙烯纤维、羟乙基纤维素、高岭土、重质碳酸钙、白水泥、氢氧化钙和预发泡的聚苯乙烯泡沫颗粒搅拌均匀，形成防火保温板原材料；加入发泡原材料搅拌均匀形成原浆料；将原浆料通过防火板制板机压制成防火保温板；养护。解决现有防火保温板抗拉强度低，保温及防火效果差的问题。
摘要（英）：

The invention discloses a polystyrene granule fireproof thermal-insulation board. The thermal-insulation board is composed of alkali-resistant mesh fabric and a fireproof thermal-insulation board main-material. The invention also discloses a preparation method of the polystyrene granule fireproof thermal-insulation board. The preparation method comprises the following steps: putting a plasticizer, a styrene-acrylic emulsion, a polymer dispersion powder, natural latex, a nonionic/anionic mixed surfactant and an MgCl2 solution into an agitator and uniformly stirring, adding a fire-proofing agent, reinforced fiber, polypropylene fiber, hydroxyethyl cellulose, kaolin, heavy calcium carbonate, white cement, calcium hydroxide and prefoamed polystyrene foam particles and uniformly stirring to form a fireproof thermal-insulation board raw-material; adding a foaming raw-material and uniformly stirring to form raw slurry; pressing the raw slurry through a fireproof board laminator to form a fireproof thermal-insulation board; and maintaining. According to the invention, the problem that existing fireproof thermal-insulation boards have low tensile strength and poor thermal-insulation and fireproof effects is solved.
