Problems solved by technology

The introduction of HIPS will make the PPO / HIPS alloy material have a wider processing window, but the mechanical properties of the alloy material will be greatly reduced, and the heat distortion temperature (HDT) will be very low
[0005] The mechanical properties and HDT values ​​of the existing PPO / HIPS alloy materials are relatively low

Abstract

The invention provides a PPO / HIPS (polyphenyl ether / high impact polystyrene) alloy material which comprises PPO resin, HIPS resin, a compatilizer, glass fiber, inorganic minerals and any other optional aids. While the ratio of resins of the PPO / HIPS alloy material provided by the invention is optimized, appropriate inorganic minerals and glass fiber are added, and the ratio of the inorganic minerals to the glass fiber is also optimized, so that not only are mechanical properties of the alloy material ensured, but also the alloy material has a high HDT (heat deflection temperature) value, a good surface effect and size stability.

Description

technical field [0001] The invention relates to a PPO / HIPS alloy material and a preparation method thereof. Background technique [0002] The current mainstream and future trend in the field of materials is "replacing metal with plastic". The biggest problem when plastic replaces metal parts is poor dimensional stability, the parts are prone to warping, and the shape is difficult to maintain. [0003] PPO (polyphenylene ether) has excellent physical and chemical properties and electrical properties, low density, extremely low water absorption, and good dimensional stability. It has been used in electronic devices in the field of home appliances and communications. However, PPO resin has low toughness, high melting point and close to its decomposition temperature, resulting in a narrow processing window and difficult production. It usually needs to be modified by adding other resins to become an alloy material. [0004] HIPS (High Impact Polystyrene) is a widely used general...
