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 rotation 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 and cool to obtain plastic granules; put the above plastic granules into an injection molding machine for injection molding to obtain the polyphenylene ether material for automotive trims.

Abstract

The invention discloses a polyphenylene oxide material for an automobile decoration part and a preparation method of the polyphenylene oxide material. The polyphenylene oxide material for the automobile decoration part comprises the following components in parts by weight: 100 parts of polyphenylene oxide, 10-20 parts of glass fibre, 4-10 parts of a compatibilizer and 0.1-0.5 part of a scratch-resistant agent. The polyphenylene oxide material for the automobile decoration part has higher tensile strength, bending strength, flexural modulus and notch impact strength.

Description

technical field [0001] The invention relates to a polyphenylene ether material for automobile decorations and a preparation method thereof, in particular to a polyphenylene ether material for automobile decorations and a preparation method thereof. Background technique [0002] Polyphenylene ether is a high-strength engineering plastic developed in the 1960s. Its chemical name is poly 2,6-dimethyl-1,4-phenylene ether, referred to as PPO (Polyphenylene Oxide) or PPE (Polypheylene ether), also known as It is polyphenylene 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. The most commonly used in the market is modified polyphenylene oxide (Modified Polyphenylene Oxide), referred to as MPPO, or MP...
