Embodiment 1

[0042] After weighing each raw material according to the data corresponding to Example 1 in Table 1, add it to a high-speed mixer for stirring, control the rotating speed at 600r / min, stir at a temperature of 90°C, and stir for 10 minutes, and then extrude and granulate through a screw extruder. Extrude at a temperature of 220° C., cool to obtain plastic granules; put the above plastic granules into an injection molding machine for injection molding to obtain the environmentally-friendly modified polyphenylene ether material for automotive interior parts.

Abstract

The invention discloses an environment-friendly modified polyphenylene oxide material for automobile interior trims. The environment-friendly modified polyphenylene oxide material for automobile interior trims comprises the following compositions in parts by weight: 100 parts of polyphenyl ether, 4-10 parts of a compatilizer, 0.1-0.5 part of a scratch-resisting agent, 0.1-0.5 part of an antistatic agent, 0.1-0.5 part of an anti-ageing agent, and 0.1-0.5 part of a corrigent. The environment-friendly modified polyphenylene oxide material for automobile interior trims possesses relatively high tensile strength, bending strength, flexural modulus and notch impact strength, excellent antistatic property, excellent anti-ageing property and no peculiar smell.

Description

technical field [0001] The invention relates to a plastic material, in particular to an environment-friendly modified polyphenylene ether material for automotive interior parts. Background technique [0002] Polyphenylene ether is a high-strength engineering plastic developed in the 1960s. Phenylene oxide or polyphenylene ether. [0003] Polyxylene is one of the cheap high-temperature plastics, but it is difficult to manufacture and its resistance to impact and heat decreases over time. Mixing polyoxyxylene and polystyrene can improve this shortcoming. In the 1960s, adjusted polyoxyxylenes came out under the trade name Noryl. Commonly used in the market is mainly modified polyphenylene ether (Modified Polyphenylene Oxide), referred to as MPPO, or MPPE (Modified Polyphenyleneether). [0004] Polyphenylene ether is non-toxic, transparent, low relative density, and has excellent mechanical strength, stress relaxation resistance, creep resistance, heat resistance, water resi...
