Abstract
The invention provides a phosphorus-containing POSS (polyhedral oligomeric silsesquioxane) flame-retardant bismaleimide resin and a preparation method thereof. The resin is composed of the following components in parts by mass: 100 parts of diphenylmethane bismaleimide, 50-100 parts of diallyl bisphenol A and 1-20 parts of poly(di(4-hydroxyphenyl)phenylphosphate) substituted chloropropyl silsesquioxane. Under the synergistic effects of the phosphorus and silicon in the poly(di(4-hydroxyphenyl)phenylphosphate) substituted chloropropyl silsesquioxane, the poly(di(4-hydroxyphenyl)phenylphosphate) substituted chloropropyl silsesquioxane can inhibit the combustion of the resin and promote the formation of the compact carbon layer, so that the resin generates a small amount of smoke and does not generate any toxic gas or corrosive gas in the combustion process and conforms to the environmental requirements. The poly(di(4-hydroxyphenyl)phenylphosphate) substituted chloropropyl silsesquioxane can react with the bismaleimide resin, and has favorable compatibility with the resin. Thus, the prepared bismaleimide resin system has the advantages of excellent mechanical properties, high flame retardancy and high temperature resistance, and can be used as an ablation-resistant material.
