Problems solved by technology

But it is dull, easy to be brittle and cracked at low temperature, and easily polluted by various harmful bacteria and molds like other plastics. Under suitable temperature and humidity conditions, it is easy to breed bacteria. Adding antibacterial raw materials, this method is easy to make the color of polypropylene products turn yellow; at the same time, due to the uneven dispersion of the added antibacterial raw materials, the antibacterial effect is not satisfactory and cannot last

Abstract

The invention provides a polypropylene plastic and the manufacture method. The components and the parts by weight are that: polypropylene 100, barium sulfate 14 to 26, coupling agent 0.1 to 0.3, antioxidant 0.1 to 0.3, dispersant 0.2 to 0.6, lubricant 0.2 to 0.6, silver antimicrobial mother material 2 to 7 and elastomer 7 to 16. The polypropylene plastic product produced by the antimicrobial polypropylene plastic with high luster and low-temperature resistance has better finish, is not easy to embrittle and break and has anti-bacterium effect. In addition, the polypropylene plastic product has surface finish not less than 70Cs (60 degree) and 24h antibacterial rate not less than 98 per cent, and has high efficiency and wide-adaptability and can keep good physical and chemical capability under the low temperature of minus 10 DEG C. to minus 20 DEG C..

Description

technical field [0001] The invention relates to a polypropylene plastic and a production method thereof, in particular to a high-gloss low-temperature resistant and antibacterial polypropylene plastic and a preparation method thereof. Background technique [0002] With the rapid development of society and the continuous improvement of people's living standards, plastic products occupy an indispensable position in people's daily life. Polypropylene is a non-toxic plastic with high heat resistance and good physical properties, which is widely used. But it is dull, easy to be brittle and cracked at low temperature, and easily polluted by various harmful bacteria and molds like other plastics. Under suitable temperature and humidity conditions, it is easy to breed bacteria. Adding antibacterial raw materials, this method is easy to make the color of polypropylene products turn yellow; at the same time, due to the uneven dispersion of the added antibacterial raw materials, the a...
