Ultrahigh-heat-resistance composite material prepared from recycled nylon and preparation method for ultrahigh-heat-resistance composite material

The invention discloses an ultrahigh-heat-resistance composite material prepared from recycled nylon and a preparation method for the ultrahigh-heat-resistance composite material. The ultrahigh-heat-resistance composite material is composed of the following components in percentages by weight: 46-89.5% of nylon, 10-50% of glass fibers, 0.5-2% of high-heat-resistance auxiliary additive master batchand 0-1% of color master batch and 0-1% of a lubricant. The ultrahigh-heat-resistance composite material provided by the invention has the following beneficial effects: according to the aging mechanism of a nylon material at a high temperature, the high-heat-resistance auxiliary additive master batch is prepared; all the components of the high-heat-resistance auxiliary additive master batch can achieve the effects of capturing free radicals, forming carbon on the surface of the nylon material and conducting heat; thus, compounding systems like glass fiber reinforced PA6, PA66 and PA6T slicescan satisfy the long-perio
