Graphite modified rock wool product and preparation method thereof
The invention relates to a graphite modified rock wool product and a preparation method thereof. The modified rock wool product is composed of rock wool yarns and graphite doped into the rock wool yarns, and the graphite accounts for 0.1%-10% of the weight of the modified rock wool product. The preparation method comprises the following steps: mixing graphite subjected to oxidation modification with phenolic resin to form a uniform dispersion liquid, uniformly dispersing modified graphite oxide in rock wool yarns along with a phenolic resin solution in the fiber forming process, and performingcotton collecting, conveying, pleating, pressurizing and curing to obtain the thermal insulation material. Another preparation process comprises the following steps: mixing graphite and phenolic resin, mechanically stirring to form a uniform dispersion liquid, uniformly dispersing the graphite into rock wool yarns along with a phenolic resin solution in the fiber forming process, and performing cotton collecting, conveying, pleating, pressurizing and curing to obtain the thermal insulation material. By adding graphite taking phenolic resin as a carrier, the heat conductivity coefficient of the rock wool product for external wall heat preservation is reduced, and the heat preservation effect of the rock wool product is improved.
本发明涉及一种石墨改性岩棉制品及其制备方法，改性岩棉制品由岩棉丝和掺入岩棉丝的石墨组成，石墨为改性岩棉制品重量的0.1％～10％。一种制备过程为：石墨经氧化改性后与酚醛树脂混合形成均匀的分散液，在成纤过程中改性氧化石墨随酚醛树脂溶液均匀的分散于岩棉丝中，经集棉、传送、打褶、加压、固化后得到保温材料；另一种制备过程为：将石墨与酚醛树脂混合通过机械搅拌形成均匀的分散液，在成纤过程中石墨随酚醛树脂溶液均匀的分散于岩棉丝中，经集棉、传送、打褶、加压、固化后得到保温材料。本发明通过添加以酚醛树脂为载体的石墨，降低了外墙保温用岩棉制品的导热系数，提高了岩棉制品的保温效果。
