Preparation method of composite flame retardant for fireproof thermal-insulation decorative plate
The invention discloses a preparation method of a composite flame retardant for a fireproof thermal-insulation decorative plate. The preparation method comprises the following steps of pulverizing hydrated silica through a ball mill to obtain hydrated silica powder, and adding an acidic solution into the hydrated silica powder to obtain a mixed liquid; adding zinc carbonate to obtain a mixed liquid containing zinc carbonate; adding aluminum hydroxide particles, silicon dioxide particles and magnesium hydroxide particles to obtain a silicon-magnesium mixed solution; adding absolute ethyl alcohol into sodium silicate, uniformly stirring, and dropwise adding an acidic solution to obtain silica-containing sol; adding the silicon-containing sol and the silicon-magnesium solution into a reactionkettle, and filtering to obtain a cured mixture; and washing and drying the cured mixture with deionized water to obtain a compound machine flame retardant. According to the preparation method, the hydrated silica powder, the zinc carbonate, the aluminum hydroxide particles and other inorganic compounds are added into the flame retardant, the flame retardant property of the flame retardant is improved, and the zinc carbonate can assist in more uniform foam forming of the decorative plate.
本发明公开了一种用于防火保温装饰板的复合阻燃剂的制备方法，所述方法包括以下步骤：将水合硅石经球磨机粉碎，得到水合硅石粉末，向水合硅石粉末中加入酸性溶液，获得混合液体，加入碳酸锌，得到含有碳酸锌的混合液，加入氢氧化铝颗粒、二氧化硅颗粒和氢氧化镁颗粒，得到硅镁系混合液；向硅酸钠中加入无水乙醇，搅拌均匀后滴加酸性溶液，得到含有硅的溶胶；将含有硅的溶胶和硅镁系溶液均加入至反应釜中，过滤，得到固化混合物；将固化混合物通过去离子水冲洗烘干，得到复合物机阻燃剂；本发明在阻燃剂中加入了水合硅石粉末、碳酸锌、氢氧化铝颗粒等无机化合物，提高了阻燃剂的阻燃性能，碳酸锌能够辅助装饰板更均匀的发泡成型。
