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

Abstract

The invention discloses antibacterial plastics for toys and a preparation method for the antibacterial plastics. The antibacterial plastics are prepared from the following raw materials in parts by weight: 30-45 parts of polyvinyl chloride, 10-25 parts of ABS engineering plastics, 1-5 parts of tin di-n-octyl dilaurate, 0.5-2 parts of calcium phosphate, 0.5-2 parts of methyl dihydrojasmonate, 1-4 parts of expandable graphite, 1-3 parts of chlorinated lauryl trimethyl ammonium, 3-5 parts of bamboo-leaf phenolic ketone and 1-5 parts of plasticizer. The antibacterial plastics for the toys have good impact resistance and play a role in inhibiting or killing bacteria, molds, yeasts, algae, even viruses and the like, which are stained to toy plastics, in operating environments, the plastics are kept clean through inhibiting the propagation of microbes, and the antibacterial effect is good; the preparation process is simple, and the production cost is relatively low; and the plastics are safe and non-toxic, so that the 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 ...
