The invention relates to a heat-insulating material, in particular to a heat-insulating anti-explosion membrane and application thereof. The heat-insulating anti-explosion membrane uses polyvinyl butyral resin as a matrix and further comprises an infrared absorber, a ultra-violet absorber, a hindered anime light stabilizer and an antioxidant, wherein the infrared absorber is a mixture of nano-calcium boride and nano-titanium dioxide. The heat-insulating anti-explosion membrane is mainly applied to producing laminated glass and lowers the cost of product while maintaining good heat-insulating performance.
