Problems solved by technology

[0004] However, due to the high cost of silver-loaded zinc-copper zeolite raw materials, the production process is complicated, and silver and copper ions are easy to precipitate and accumulate in the human body, which is not conducive to health. Therefore, the popularization and application of nano-bamboo charcoal chopsticks is limited.

Abstract

The invention discloses nano bamboo charcoal chopsticks and a preparation method thereof. The nano bamboo charcoal chopsticks are formed by injection molding of antibacterial plastic. The antibacterial plastic is an inorganic / organic composite material prepared by blending the following raw materials, by weight: 10-20 parts of nano TiO2 modified bamboo charcoal powder, 30-50 parts of polyethyleneglycol terephthalate, 15-30 parts of polybutylene terephthalate, 15-25 parts of glass fibers and 0.3-0.5 part of a coupling agent. The nano TiO2 modified bamboo charcoal powder is added into the glass-fiber-reinforced PET / PBT blended composite material, so that the strength of the chopsticks is further improved; meanwhile, the effects of preventing mildew, inhibiting bacteria, killing bacteria andremoving peculiar smell are achieved. Particularly, the antibacterial and bactericidal effects on escherichia coli and staphylococcus aureus are obvious.

Description

technical field [0001] The invention relates to tableware, in particular to plastic chopsticks with antibacterial effect. Background technique [0002] Chopsticks are the main tableware for holding food in daily life. Common chopsticks are made of wood, plastic, and metal. In the process of people using chopsticks, because chopsticks are in a damp state or placed in an unventilated place for a long time, bacteria or mildew are easy to grow, which affects the aesthetics of chopsticks and even endangers people's health. [0003] The authorized announcement number is CN106108568B, which is a kind of nano-bamboo charcoal chopsticks. The chopsticks are prepared by adding the polypropylene resin with silver-loaded zinc-copper zeolite antibacterial agent. Because the zeolite has a porous structure, the specific surface area is large, and the zeolite knot has a strong cationic Exchange capacity is a natural antibacterial agent carrier; silver ions, zinc ions, and copper ions all h...
