摘要
Abstract
Polyurethane rigid foam was prepared by introducing nano-SiO2 and basalt fiber into polyurethane matrix. The effects of isocyanate index, contents of water, nano-SiO2 and basalt fiber, length of basalt fiber on the impact property were studied. When the isocyanate index was 1.05, content of nano-SiO2 was 3.0%, and content of 5.0 mm basalt fiber was 3.0 %, the best value of impact strength was obtained.关键词
