High-density thermoplastic plastic for entertainment industry chips and preparing method of plastic

Abstract

The invention discloses a high-density thermoplastic plastic for entertainment industry chips and a preparing method of the plastic. The plastic comprises 10-30 parts by weight of polyphenylene sulfide, 50-90 parts by weight of metal powder, 0-10 parts by weight of flexibilizer, 0-1 part by weight of lubricant and 0-5 parts by weight of colorant. The preparing method of the plastic includes the steps of adding polyphenylene sulfide, flexibilizer, lubricant and colorant into a mixer to be mixed in proportion to obtain a mixture, putting the mixture into a main feeding port of a twin-screw extruder through a weightless feeder, putting iron powder into a side feeding port of the extruder through a vibration feeder, conducting melting and mixing to extrude a strip-shaped object, conveying thestrip-shaped object through a conveying belt to a granulator to be granulated, cooled and packaged to obtain a finished product. The physical strength and appearance quality of the prepared plastic are remarkably improved.

Description

technical field [0001] The invention relates to the field of engineering plastic composite materials, in particular to a high-density thermoplastic used for chips in the entertainment industry and a preparation method thereof. Background technique [0002] The substrates of chips used in the entertainment industry are mostly metal or plastic composite materials. The advantages of metal materials are high density and good texture, but the processing of metal materials is difficult and the cost is high; plastic composite materials are generally filled with general-purpose resins such as polypropylene or polyvinyl chloride or polyethylene terephthalate with a low melting point. Inorganic minerals are used to increase the specific gravity of composite materials and improve the feel of chips. The density is generally around 2.5g / cm3, which is lower than the density of metal materials, and the feel and surface texture are slightly worse than metal materials. General-purpose resin...

Problems solved by technology

The advantages of metal materials are high density and good texture, but the processing of metal materials is difficult and the cost is high; plastic composite materials are generally filled with general-purpose resins such as low-melting polypropylene or polyvinyl chloride or polyethylene terephthalate. Inorganic minerals are used to increase the specific gravity of composite materials and improve the feel of chips. The density is generally around 2.5g / cm3, which is lower than the density of metal materials, and the feel and surface texture are slightly worse than metal materials. General-purpose resins such as ethylene glycol phthalate have low physical strength, so the prepared products have low physical strength and are easily damaged during long-term use
