耐烧蚀防热隔热涂层的研制
Development of Ablation and Heat-Resistant and Heat Insulation Coating
摘要
Abstract
According to identity of flying task in some solid rocket motor as well as the mechanism study of heat-resistant and heat insulation of coating, a kind of heat-resistant and heat insulation coating was prepared on the basis of epoxy resin grafted by silicone, mixed by temperature-resistant mixture filling and additive. The optimum parts of poly-phosphate ammonium、aluminium hydroxide and boric acid are 4,6,3 respectively, by using L9(33 ) orthogonal experiment. The results of the coating tests of the final optimum prescription; its line ablation rate is 0. 116 mm/s,the heat conductivity is 0. 28 W/(m ·K) 、the density is 1.28 g/cm3,the adhesion strength is 11.84 Mpa,all show that the coating is of good combination of performances, especially good heat-resistant and heat insulation characteristics, which can satisfy the need of requirement of outer heat-resistant in solid rocket motor.关键词
