阻燃耐热覆铜板的制备方法
摘要：
本发明涉及一种阻燃耐热覆铜板的制备方法，包括以下步骤，以纳米二氧化硅泡沫、十二烷基苯磺酸、五水硝酸铋和甲基三氯硅烷、聚氧乙烯山梨醇酐单油酸酯为原料得到填料；以DOPO与双酚A氰酸酯单体、酚化合物、间硝基苯磺酸吡啶盐、2，3-环氧基环戊基环戊基醚、亚磷酸二甲酯为原料得到树脂预聚物；将填料加入邻苯二甲酸二缩水甘油酯中，得到活性填料；将树脂预聚物与吲哚化合物混合，然后加入活性填料、异构十一醇聚氧乙烯醚磷酸酯钾盐，得到复合体系；将复合体系、增强材料、金属箔热压成形，即可得到所述阻燃耐热覆铜板，其具有优异的阻燃性能、耐热性能，满足阻燃耐热覆铜板的发展应用。
摘要（英）：

The present invention relates to a flame-resistant and heat-resistant copper clad laminate preparation method, which comprises: adopting nanometer silica foam, dodecyl benzenesulfonic acid, bismuth nitrate pentahydrate, methyl trichlorosilane and polyoxyethylene sorbitan monooleate as a raw materials to obtain a filler; adopting DOPO, a bisphenol A cyanate ester monomer, a phenol compound, a m-nitrobenzene sulfonic acid pyridine salt, 2,3-epoxy cyclopentyl cyclopentyl ether and dimethyl phosphonate as raw materials to obtain a resin prepolymer; adding the filler to o-phthalic acid diglycidyl este to obtain an active filler; mixing the resin prepolymer and an indole compound, and then adding the active filler and isomeric undecanol polyoxyethylene ether phosphate potassium salt to obtain a composite system; and carrying out hot pressing molding on the composite system, a reinforced material and metal foil to obtain the flame-resistant and heat-resistant copper clad laminate, wherein the flame-resistant and heat-resistant copper clad laminate has characteristics of excellent flame retardant property and excellent heat resistance, and meets the development applications of the flame-resistant and heat-resistant copper clad laminate.
