Abstract

The invention relates to a preparation method of an anti-aging high-flame-resistant ABS automotive interior trim. The preparation method comprises the following steps: S1, putting high-flame-resistant ABS material particles in a stirring machine, carrying out stirring fusion at the temperature of 110 to 120 DEG C, and cooling a fused material to 60 to 80 DEG C for later use; S2, rolling the fused material in the step S1 to form a sheet material, using rolling equipment to roll the fused material at the temperature of 60 to 80 DEG C, then cooling the sheet material formed by rolling to room temperature, and forming the sheet material with the thickness of 5 to 10 mm; S3, cutting the sheet material to form a blank, performing hot-pressing on the blank to form the automotive interior trim, using hot-pressing equipment to perform hot-press on the blank under the hot-press pressure of 1000 to 1200 kN at the hot-press temperature of 65 to 75 DEG C, and thus forming the high-flame-resistant ABS automotive interior trim. The anti-aging high-flame-resistant ABS automotive interior trim is formed by processing the following raw material in parts by weight: 80 to 100 parts of ABS resin, 40 to 60 parts of PC resin, 5 to 15 parts of EPDM resin, 6 to 10 parts of an antioxidant and 8 to 12 parts of a composite flame retardant. The flame-resistant ABS plastic disclosed by the invention has relatively high flame resistance, is used for manufacturing the automotive interior trim, and is reliable in quality and high in safety.

Description

technical field [0001] The invention relates to a preparation method of an anti-aging high flame-retardant ABS automotive interior part. Background technique [0002] ABS resin (acrylonitrile-styrene-butadiene copolymer) is a thermoplastic polymer material structure with high strength, good toughness and easy processing. [0003] ABS is a general-purpose thermoplastic engineering plastic developed in the 1940s. It is a plastic variety with excellent comprehensive mechanical properties. It not only has good rigidity, hardness and processing fluidity, but also has high toughness. It can be injected, extruded or heated. forming. [0004] Most of the auto parts are processed by injection molding method, the advantages of ABS resin are impact resistance, sound insulation, scratch resistance, better heat resistance, more beautiful than PP, especially suitable for transverse impact resistance and use Temperature-critical parts. ABS resin is the third largest resin used in automo...
