Modified rock wool product and preparation method thereof
The invention relates to a modified rock wool product and a production method. The rock wool product is composed of rock wool yarns and modification additives doped into rock wool, and the modification additives are graphite, SiO2 aerogel and graphite-SiO2 aerogel. The production method comprises the steps that raw materials are subjected to high-temperature melting, centrifugal throwing and high-pressure blowing separation to obtain rock wool yarns, and the rock wool product is obtained after cotton collecting, conveying, pleating, pressurizing and curing, wherein a modifier adding port is formed in the front end of a blowing separation air outlet, and the modification substances are loaded in blowing separation air through the siphonic effect and are evenly attached to the rock wool yarns through high-pressure blowing separation. The modification additives are doped into the rock wool yarns, so that the prepared modified rock wool product is low in heat conductivity coefficient and good in heat preservation effect. The modification additives are added by using high-pressure blowing separation air. The modified rock wool product and the production method have the advantages that the method is simple and convenient, the production cost is low, and the thermal insulation property of the product is high.
本发明涉及一种改性岩棉制品及生产方法，岩棉制品由岩棉丝和掺入岩棉的改性添加物组成，改性添加物为石墨、SiO气凝胶和石墨‑SiO气凝胶。生产方法包括：将原料经高温熔融、离心甩制、高压吹离，制备出岩棉丝，经集棉、传送、打褶、加压、固化后得到岩棉制品，其中在吹离风出口前端开设改性剂添加料口，通过虹吸效应将改性物质负载于吹离风中，经高压吹离均匀附着于岩棉丝上。本发明在岩棉丝中掺入改性添加物，制备的改性岩棉制品导热系数低，保温效果好。利用高压吹离风添加改性添加物，具有方法简便，生产成本低，产品保温性能高的优点。
