High-temperature-resistant environment-friendly plastic particle and preparation method thereof

Abstract

The invention discloses a high-temperature-resistant environment-friendly plastic particle and a preparation method thereof, belonging to the technical field of plastic production. The high-temperature-resistant environment-friendly plastic particle comprises the following components: polyethylene, polyvinyl chloride, linear low-density polyethylene, titanium dioxide, a light stabilizer, an antibacterial agent, a reinforcing agent, an antioxidant, a heat stabilizer, a plasticizer and the like. The preparation method of the high-temperature-resistant environment-friendly plastic particle comprises the steps of raw material preparation, raw material component blending, extrusion granulation, cooling packaging and the like. The high-temperature-resistant environment-friendly plastic particleis not prone to breeding bacteria, fungi and viruses, wide in an antibacterial spectrum, capable of achieving continuous antibacterial action, long in antibacterial time, excellent in weather resistance and ageing resistance, long in service life, high in strength, good in toughness, good in heat resistance and good in environment friendliness. The preparation method is simple in process and easyto operate; the raw material components are blended through a mixing device, mixing efficiency is high, and mixing dead corners are effectively avoided; and the preparation method is suitable for massproduction.

Description

technical field [0001] The invention relates to the technical field of plastic production, and more specifically relates to a high-temperature resistant and environmentally friendly plastic particle and a preparation method thereof. Background technique [0002] With the development of the plastics industry and the improvement of people's living standards, many items used in daily life contain plastic materials, such as telephones, bathtubs, toilets, toys, interior decoration materials, refrigerators, food packaging bags, plastic containers And public plastic products and other products, these items are easily contaminated and breed bacteria, and mold will grow in the dark. In order to achieve the purpose of sanitation and deodorization, this has promoted the rapid development of antibacterial plastic products. [0003] Existing antibacterial plastics are prepared by adding antibacterial agents to plastic raw materials. Although the resulting products have antibacterial func...

AI Technical Summary

Problems solved by technology

[0003] Existing antibacterial plastics are prepared by adding antibacterial agents to plastic raw materials. Although the resulting products have antibacterial functions, their antibacterial range is small and the duration is short, which is far from meeting the long-term and spectral antibacterial requirements. Therefore, It is necessary to improve the existing technology and develop a kind of antibacterial plastic particles with strong antibacterial properties
