杂化酚醛树脂/玻璃纤维隔热瓦的制备及性能研究
Preparation and performance study of hybridphenolic resin/glass fiber insulation tiles
摘要
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,me-chanical properties and thermal insulation performance of the insulation tiles were specifically investigated.The re-sults indicate that TEOS has good compatibility with phenolic resin and the rigid and flexible dual network interpene-trating structure can be successfully constructed.The prepared fiber glass tiles all have typical quasi-laminar distri-bution with densities range from 0.20 to 0.26 g/cm3.Among them,GIT-100 has the best comprehensive perform-ance.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 compres-sive 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℃.关键词
