摘要/Abstract

摘要： 本文以短切玻璃纤维为骨架,TEOS改性酚醛树脂为黏结剂,采用真空抽滤法制备出一种低成本、耐中低温隔热需求的玻璃纤维隔热瓦(GIT),并具体探究了杂化树脂黏结剂对隔热瓦的微观形貌、力学性能、隔热性能的影响规律。结果表明,TEOS与酚醛树脂相容性良好,能成功构建刚柔相结合的双网络互穿结构。制备的玻璃纤维隔热瓦均具有典型的准层状分布,密度为0.20~0.26 g/cm³。其中,GIT-100的综合性能最好,Z向、X/Y向压缩强度分别在应变为5.1%、4.2%时呈现最大值0.695 MPa、3.546 MPa,压缩形变为15%时的回弹率高达90%,室温热导率为0.047 5 W/(m·K),经400 ℃热处理后压缩强度下降12.5%。

Abstract: This paper used chopped glass fibers as the skeleton structure and TEOS-modified phenolic resin as the binder to prepare a low-cost, medium- and low-temperature-resistant insulation glass fiber insulation tiles (GIT) by vacuum filtration method, and the influence laws of the hybrid resin binder on the microscopic morphology, mechanical properties and thermal insulation performance of the insulation tiles were specifically investigated. The results indicate that TEOS has good compatibility with phenolic resin and the rigid and flexible dual network interpenetrating structure can be successfully constructed. The prepared fiber glass tiles all have typical quasi-laminar distribution with densities range from 0.20 to 0.26 g/cm³. Among them, GIT-100 has the best comprehensive performance. The compressive strength in Z direction and X/Y direction shows maximum value of 0.695 MPa and 3.546 MPa at the strain of 5.1% and 4.2%, respectively, the rebound resilience ratio is as high as 90% at the compressive deformation of 15%, the thermal conductivity at room temperature is 0.047 5 W/(m·K), and the compressive strength decreases by 12.5% after heat treatment at 400 ℃.
