Abstract

The invention discloses a flame-retardant thermoplastic elastic crash pad and a preparation method thereof. The flame-retardant thermoplastic elastic crash pad is characterized by comprising the following raw materials by weight: 45 to 55 parts of hydrogenated styrene-butadiene copolymer L606, 20 to 25 parts of polyisoprene resin, 30 to 40 parts of SIS resin, 6 to 8 parts of EPDM-maleic anhydride graft, 3 to 5 parts of naphthenic rubber oil, 7 to 9 parts of a fire retardant, 5 to 8 parts of a mineral filler, 0.3 to 0.5 part of tris(2,4-di-tert-butylphenyl)phosphite and 0.6 to 0.8 part of silicone powder. According to the invention, the effective loading amount of a catalyst is easy to control; catalysis efficiency is high; good elasticity can be easier to maintain at a low temperature; and the prepared crash pad has high elasticity, permanent compression deformation and UL-94V-0-grade flame retardation effect, and is a highly damping material with low resilience.

Description

technical field [0001] The invention belongs to the technical field of shockproof materials, and in particular relates to a flame-retardant thermoplastic elastic shockproof pad and a preparation method thereof. Background technique [0002] Rubber is a relatively common shock-absorbing material. It has certain advantages due to its superior shock-absorbing performance and aging resistance. However, rubber has disadvantages such as long vulcanization cycle and difficult molding, which limit its large-scale use to a certain extent. Thermoplastic elastomers It has many advantages such as direct injection molding and recyclable utilization, so it has become a research hotspot. But at present, the main flame-retardant thermoplastic elastomer materials are halogen-containing materials, which do not conform to the environmental protection policies of many countries and are not conducive to the export of our products. [0003] Shockproof pads generally use butyl rubber. The biggest...
