Abstract

The invention discloses high-density wear-resistant PPS plastic and a preparation method thereof. The high-density wear-resistant PPS plastic is prepared from, by weight, 100 parts of polyphenylene sulfide, 30-35 parts of metal powder, 8-10 parts of a mineral powder composition, 5-10 parts of a flexibilizer, 1-3 parts of a lubricant and 10-15 parts of a coupling agent. The preparation method comprises the following steps of: firstly, using a coupling agent to carry out surface modification on metal powder and a mineral powder composition, and mixing to obtain a heavy filler; secondly, adding polyphenylene sulfide, a flexibilizer, a lubricant and a heavy filler into a mixing smelting machine, and uniformly mixing to obtain a molten mixture; and thirdly, discharging the molten mixture from the mixing smelting machine, feeding the molten mixture into a double-screw extruder for further mixing and extrusion, and then pelletizing, cooling and packaging to obtain the high-density wear-resistant PPS plastic. The problem that a product is cheap and poor in wear resistance and the surface of the product is easy to wear due to low density and low weight of PPS plastic is solved.

Description

Technical field[0001]The invention belongs to the technical field of PPS plastic preparation, and specifically relates to a high-density wear-resistant PPS plastic and a preparation method thereof.Background technique[0002]Polyphenylene sulfide (PPS) is a special engineering plastic with excellent performance. It has excellent heat resistance, flame retardancy, chemical resistance, electrical insulation and high mechanical strength. The strength retention rate at high temperatures is far Higher than other engineering plastics such as PBT, PES, PC, with a density of 1.36g / mL and a melting point of 285°C, its excellent performance and wide range of uses have made PPS the first production of special engineering plastics and the sixth among engineering plastics . However, the shortcomings of high brittleness and low impact strength of PPS limit its application in a wider field. The modification of PPS therefore has important theoretical significance and practical value.[0003]Plastics ha...
