Method for preparing heat-insulating hollow roof tile by using basalt composite staple fiber
The invention discloses a heat-insulating hollow roof tile. The invention further discloses a method for preparing the heat-insulating hollow roof tile by using the basalt composite staple fiber. Themethod comprises the following steps of mixing the basalt staple fiber and a plant fiber evenly, and calcinating under the protection of nitrogen to obtain a pretreated fiber; dispersing the pretreated fiber and polyvinyl alcohol in water, adjusting the temperature, adjusting the pH value of a system to be 10 to 11, adding hydrogen peroxide and continuing to stir, adding gamma-glycidoxypropyltrimethoxysilane, continuing to stir, heating up, adding polyvinyl chloride and stirring, filtering, washing, drying, and crushing to obtain the basalt composite staple fiber; mixing polyvinyl chloride andpolyurethane, stirring evenly at 90 to 120 DEG C, adding the basalt composite staple fiber, a reinforcing agent, a plasticizer, and a coloring agent and continuing to stir for 5 to 15 minutes to obtain a mixture; and feeding the mixture into a twin-screw extruder for extrusion, and feeding an extruded material into a mold for forming, demolding and then cooling and forming to obtain the heat-insulating hollow roof tile.
本发明公开一种隔热中空屋顶瓦。本发明还公开一种采用玄武岩复合短纤维制备隔热中空屋顶瓦的方法，包括：将玄武岩短纤维、植物纤维混合均匀，氮气保护下煅烧得到预处理纤维；将预处理纤维、聚乙烯醇分散在水中，调节温度，调节体系pH值为10‑11，加入双氧水继续搅拌，加入γ‑缩水甘油醚氧丙基三甲氧基硅烷继续搅拌，升温，加入聚氯乙烯搅拌，过滤，洗涤，干燥，粉碎得到玄武岩复合短纤维；将聚氯乙烯、聚氨酯混合，90‑120℃搅拌均匀，加入玄武岩复合短纤维、补强剂、增塑剂、着色剂继续搅拌5‑15min，得到混合料；将混合料送入双螺杆挤出机中挤出，将挤出料送入模具中成型，脱膜后冷却定型，得到隔热中空屋顶瓦。
