Abstract

The invention discloses a high-and-low-temperature-resistant automobile interior trim and a preparation method thereof. The automobile interior trim is made from, by weight part, 38-53 of tetrafluoroethylene-hexafluoropropylene copolymer resin, 26-42 of polyetherimide, 21-35 of silicone plastic, 18-27 of boron nitride, 16-23 of diisodecyl adipate, 2-3 of cobalt 2-ethylhexanoate, 1-2 of cadmium 2-ethylhexanoate, 10-15 of brominated paraffin, 17-24 of octyl epoxy stearate, 4-7 of 2-methylhydroquinone, 5-10 of triglycidyl trimellitate, and 15-20 of periclase powder. Through mixing of tetrafluoroethylene-hexafluoropropylene copolymer resin, polyetherimide, and silicone plastic, through addition of diisodecyl adipate as a cold resistant plasticizer, through addition of octyl epoxy stearate as aheat resistant plasticizer, and through development of functions of the raw materials above, the prepared automobile interior trim is excellent in high and low temperature resistance, can be used atthe temperature in a range of from -250 to 300 DEG C for a long time, and is excellent in corrosion resistance, wear resistance, water resistance and ozone aging resistance.

Description

Background technique [0001] The invention relates to a plastic floor and a preparation method thereof, in particular to a high and low temperature resistant automotive interior part and a preparation method thereof. Background technique [0002] Plastics are easy to match with different materials, convenient in design, diverse in appearance, good in processability, light in weight, easy to clean, long in service life, low in mass production, high in specific strength and specific modulus, etc. Quantitative requirements, widely used in the field of automotive interior parts, can be used for instrument panels, seats, roofs, door inner panels, sub-dashboards, armrests, carpets, trunk linings, engine hood linings and various Felt pads for sound absorption and noise reduction, etc. With the rapid development of the automobile industry, the requirements for plastic interior parts are getting higher and higher, and the high and low temperature resistance of traditional plastic int...
