The invention discloses a high-flame-retardant anti-corrosion glass fiber asphalt shingle and a preparation method thereof, and relates to the technical field of building materials. According to the preparation method, long fibers prepared from nylon, melamine polyphosphate and glass fibers through microwave-assisted melt pultrusion are mixed with asphalt, so that the viscosity of a matrix is improved, permeation of water molecules is retarded, and the waterproof and anticorrosive effects are achieved; 3-methoxy-2-methylchloromethacrylonitrile is used for preparing a fiber membrane through magnetic field-electrostatic spinning, then laser is used for assisting low-pressure spraying of graphene, the surface of the asphalt shingle is covered with the graphene, a compact physical isolation layer is formed, and therefore the waterproof, anti-corrosion and flame-retardant performance of a base body is improved; 3-isocyanatopropyltriethoxysilane is utilized to modify pentaerythritol phosphate to prepare a flame retardant, and after dual curing, a film with excellent performance is formed on the surface of a matrix, so that internal materials are effectively protected, and the flame retardance is enhanced. The prepared glass fiber asphalt shingle has waterproof, anti-corrosion and flame-retardant effects.
本发明公开了一种高阻燃防腐玻纤沥青瓦及其制备方法，涉及建筑材料技术领域。本发明先利用尼龙、聚磷酸三聚氰胺和玻璃纤维通过微波辅助熔融拉挤制备的长纤维，与沥青混合，增大基体的黏稠性，阻滞水分子的渗透，实现防水、防腐的效果；接着利用3‑甲氧基‑2‑甲氯基甲基丙烯腈通过磁场‑静电纺丝制得纤维膜，再利用激光辅助低压喷涂石墨烯，覆在沥青瓦表面，形成致密的物理隔绝层，从而提高基体的防水、防腐、阻燃性能；利用3‑异氰酸基丙基三乙氧基硅烷改性季戊四醇磷酸酯制得阻燃剂，经双重固化后，在基体表面形成具有优异性能的膜，有效保护内部材料，从而增益阻燃性。本发明制备的玻纤沥青瓦具有防水、防腐、阻燃的效果。
