Antibacterial plastic for toys and preparation method of antibacterial plastic

Abstract

The invention discloses antibacterial plastic for toys and a preparation method of the antibacterial plastic. The antibacterial plastic is prepared from raw materials in parts by weight as follows: 30-45 parts of polyvinyl chloride, 10-25 parts of ABS engineering plastic, 1-5 parts of dioctyldilauryltin, 0.5-2 parts of calcium phosphate, 0.5-2 parts of methyl dihydrojasmonate, 1-4 parts of polysaccharide, 1-3 parts of chlorinated dodecyl trimethyl ammonium, 3-5 parts of bamboo leaf phenolic ketone and 1-5 parts of betaine. The antibacterial plastic for toys has good impact resistance, have inhibition or killing functions on bacteria, mildew, yeast, algae and even viruses staining toy plastic in the use environment, keeps clean by inhibiting breeding of microorganisms and has a good antibacterial effect; a preparation process is simple, and the production cost is lower; the antibacterial plastic is safe and non-toxic, and physical health of children is protected.

Description

technical field [0001] The invention relates to a plastic, in particular to an antibacterial plastic for toys and a preparation method thereof. Background technique [0002] Toys play an important role in children's lives, and toys are children's friends. Plastics used to make toys must be safe, healthy and non-toxic. But in daily life, quite a few harmful bacteria exist and multiply on the surface of plastic products, and cause various diseases through contact. As people's awareness of health and environmental protection continues to increase, there is a demand for "bacteriostasis and sterilization" for toy plastic parts that are frequently in contact with in daily life. [0003] The core component of antibacterial plastics is antibacterial agent. Organic antibacterial agents are limited in their application due to their lack of safety, heat resistance, antibacterial persistence, and broad-spectrum antibacterial properties; natural antibacterial agents have low toxicity ...

AI Technical Summary

Problems solved by technology

Silver ions have the strongest antibacterial performance, but their chemical properties are lively, and they are easily converted into brown silver oxide or black elemental silver, so they should not be used in large quantities in white toys

The antibacterial strength of zinc is only 1 / 1000 of that of silver; copper ions are colored, and a large amount of use will affect the appearance of the product

Although metal ions are quick to kill bacteria, the cost of using a large amount is high, and the release of heavy metal ions will have adverse effects on the environment and human health

The latter has high photocatalytic activity, strong antibacterial persistence, low price and non-toxicity, and strong self-cleaning function. Light exposure applications are limited

A variety of compound antibacterial agents have appeared on the market, but the antibacterial effect is still not good enough; and the preparation methods of existing toy plastics are complicated, which increases the production cost
