Abstract

The invention discloses a PC/PET alloy material prepared by the utilization of waste PC and PET materials. a preparation method of the PC/PET alloy material comprises the following steps: washing and crushing waste polycarbonate and poly(ethylene terephthalate) resin materials, adding auxiliaries such as a lubricant, a fire retardant, a fortifier and the like, fully mixing, and heating and conducting compression moulding forming to prepare the polycarbonate/poly(ethylene terephthalate) resin alloy material. The prepared material has high heat resistance, good toughness and impact strength and good flame retardancy, and is not easy to crack.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a PC / PET alloy material prepared from waste PC and PET materials. Background technique [0002] Polyethylene terephthalate (PET) has excellent properties such as high strength, heat resistance, and abrasion resistance, and is very popular in the textile industry and other industries. At present, PET fiber has become the most productive variety among synthetic fibers. In addition, PET is also widely used in the field of packaging and film due to its excellent mechanical strength, light weight, chemical solvent resistance, barrier properties and excellent transparency. Although PET has many excellent properties, there are also some shortcomings, such as poor impact resistance, slow crystallization speed, uneven crystal structure, easy water absorption, large shrinkage of molded products, rough surface of products, etc., which limit its wide application. , which is cause...
