Preparation process of high-performance PC material

Abstract

The invention discloses a preparation process of a high-performance PC material. The preparation process comprises the following steps: melting, quickly cooling, discharging, annealing, and forming. A finished product prepared from PC high molecules as raw materials is relatively high in toughness. The product is subjected to heat treatment by adopting an annealing process, the formed product is free of color change, ageing and cracking, is relatively high in rigidity and can be dismounted and mounted for multiple times, and the service life of the formed product is remarkably prolonged. Through detection, both temperature resistance and temperature interchange resistance of the material can meet the industry standards; detection results are all higher than regulations of the industry standards by testing the tensile strength, bending strength and cantilever beam shock of the material. The process is simple in equipment, convenient to carry out, relatively quick in formation and suitable for large-scale production.

Description

technical field [0001] The invention relates to a plastic material, in particular to a method for preparing a forming material using PC (polycarbonate) as a raw material. Background technique [0002] Because of its characteristics of not being fragile and not easy to break, many existing items are made of plastic materials. Therefore, the scope of use of plastics is becoming wider and wider. Lampshades and carpet beading used in airplanes, trains or automobiles are all made of plastic materials. The plates used on these objects need longer service life and better use effects, but traditional operations cannot produce products that meet the requirements. required material. [0003] The existing production process uses PVC as raw material to prepare, but due to the material problems of PVC itself, the objects formed after a period of use often appear discoloration, brittle, and even cracks; some also use nylon as raw material To prepare, but the forming process is very diff...

Problems solved by technology

Lampshades and carpet beading used in airplanes, trains or automobiles are all made of plastic materials. The plates used on these objects need longer service life and better use effects, but traditional operations cannot produce products that meet the requirements. required material

[0003] The existing production process uses PVC as raw material to prepare, but due to the material problems of PVC itself, the objects formed after a period of use often appear discoloration, brittle, and even cracks; some also use nylon as raw material to prepare, but the forming process is very difficult, and the formed product cannot be used repeatedly, the cost is high, and the rigidity is poor

As a very good thermoplastic resin, PC will have a better effect when used as a raw material for plastic products, but there are many difficult problems in the production process, and the molded products also have the common brittleness of plastics, so It is necessary to adopt a better process method so that the products formed according to this method can overcome the above problems and have better use effects
