Problems solved by technology

However, the tensile strength and bending strength of PPS are at the middle level among engineering plastics, but the elongation and impact strength are relatively low. The existing technology uses high filling to improve the thermal conductivity of PPS, which further reduces the physical properties of PPS. Limits the application of PPS

Abstract

The invention discloses a PPS (Poly-Phenylene Snlfide) / PPO (Poly-Phenylene Oxide) / PA (Poly-Amide) alloy with high temperature resistance and high heat conductivity and a preparation method of the PPS / PPO / PA alloy, which belongs to the technical field of high molecular materials. The PPS / PPO / PA alloy is prepared from PPS, PPO, PA, a toughening compatilizer, a heat conduction agent, carbon fibers, an antioxidant and processing additives. The preparation method of the PPS / PPO / PA alloy comprises the following steps: firstly coupling main components of the heat conduction agent, jointly stirring and mixing the main components of the heat conduction agent with other raw materials except the carbon fibers, adding the mixed materials into a zone 1 of total 10 zones of a twin-screw extruder, adding the granulated carbon fibers after being subjected to surface treatment into a zone 10, extruding, granulating, drying and carrying out injection molding to obtain the PPS / PPO / PA alloy. The PPS / PPO / PA alloy with high temperature resistance and high heat conductivity is high in heat conduction coefficient and has the characteristics of high strength, high impact, good processing property and the like.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a PPS / PPO / PA alloy with high temperature resistance and high thermal conductivity and its preparation method and application. Background technique [0002] Metal materials are electrical and thermal conductive materials in the traditional concept, but with the advancement of polymer science and technology, polymer materials have also become a new role in the field of electrical conductivity and thermal conductivity, which subverts the traditional concept of thermal insulation of polymer materials. Conductive polymer materials are a research hotspot in recent years, and thermally conductive polymer materials have gradually been paid attention to with the continuous expansion of application fields, such as heat exchange engineering, electromagnetic shielding, electrical and electronic, friction materials, etc. The vigorous development of the information industry in recent...
