Problems solved by technology

[0003] Among them, polyethylene, polypropylene and polyvinyl chloride are the most widely used, and the amount of use is relatively large. However, with the improvement of material requirements in various fields, these materials can no longer fully meet people's needs.
Especially for some home appliances and electronic equipment fields, people not only have higher requirements for the performance of materials, but also gradually have higher requirements for the environmental protection and color gloss of the materials themselves. As a new type of environmentally friendly materials, polyethylene Various properties are relatively excellent, but its gloss is poor, which cannot meet people's needs

Abstract

The invention relates to the field of high polymer materials, in particular to a high polymer material for surface high-gloss injection molding. The high polymer material comprises the following components in parts by weight: 50-80 parts of low-density polyethylene, 20-40 parts of polyoxyethylene, 10-15 parts of modified glass fiber, 2-8 parts of a light stabilizer, 1-10 parts of an antioxidant and 3-10 parts of a pigment. The high polymer material of the invention solves the problem that polyethylene serving as a novel environment-friendly material is relatively excellent in various properties, but relatively poor in glossiness and cannot meet the demands of people. According to the high polymer material for surface high-gloss injection molding provided by the invention, the combination of low-density polyethylene and polyoxyethylene can greatly reduce the cost of the material and enhance the market competitiveness of the material; and the modified glass fiber is added, so the glossiness of the material can be greatly improved, related use requirements are met, and the high polymer material has wide market prospects and commercial values.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a polymer material for surface highlight injection molding. Background technique [0002] Polymer materials are mainly divided into different types such as plastics, rubber, fibers, adhesives, coatings, etc. Among them, plastic materials and rubber are used more, and plastic materials are used most frequently. Plastics can be divided into Thermoplastics and thermosetting plastics, thermoplastics include polyethylene, polypropylene, polystyrene, polymethyl methacrylate, polyvinyl chloride, nylon, polycarbonate, polyurethane, polytetrafluoroethylene, polyethylene terephthalate Alcohol esters, etc.; thermosetting plastics. The common ones are epoxy resin, phenolic plastic, polyimide, melamine formaldehyde resin and so on. [0003] Among them, polyethylene, polypropylene, and polyvinyl chloride are the most widely used, and the amount of use is relatively large. However, with the i...
