Antibacterial masterbatches used for plastic toys and preparation method of antibacterial masterbatches

Abstract

The invention provides antibacterial masterbatches used for plastic toys and a preparation method of the antibacterial masterbatches. The antibacterial masterbatches comprises the following raw materials by weight percent: 65-85% of plastic resin, 10-25% of a natural antibacterial agent, 3-5% of cumin seed oil, 0.5-2% of polyethylene wax, and 1.5-3% of a coupling agent. According to the invention, the raw materials are prepared into the masterbatches through various processing means, the raw materials achieve synergistic interaction, and the effects of the raw materials complement each other; when applied to plastic toys, the masterbatches are wide in antibacterial spectrum, high in antibacterial rate, good in antibacterial property, and long-lasting in bacteria prevention, prevent microbes such as various harmful bacteria, moulds and viruses from breeding on toys, and have excellent aging resistance and better mechanical property, and the service life can be greatly prolonged; besides, the masterbatches slowly release fragrance and health protection components, and automatically emit far infrared rays, thereby achieving the effects of purifying the environment and eliminating peculiar smell, having the functions of self-cleaning and health care, enabling children to gain more health benefits, and having high practical value.

Description

technical field [0001] The invention belongs to the field of functional new materials, and in particular relates to an antibacterial masterbatch for plastic toys and a preparation method thereof. Background technique [0002] Toys are children's first textbook. Using toys to play games can not only enrich children's lives and gain happiness, but also cultivate children's interest in the process of playing, which plays a very good role in developing children's intelligence and imagination. With the progress of society, toys are used more and more frequently, and there are more and more types. According to the materials, they can be divided into metal toys, plastic toys, rubber toys, bamboo toys, cloth toys, paper toys, etc. Among them, Due to the advantages of light weight, easy to move, good shape, flexible and diverse colors, easy to form and process, and economical, plastic toys are occupying a higher and higher proportion of toys. However, there are defects such as easy ...

AI Technical Summary

Problems solved by technology

However, natural antibacterial agents are usually extracted from a plant, animal or organism. The antibacterial component is single and the antibacterial range is narrow. It has poor compatibility with plastics, and there are problems such as agglomeration and uneven dispersion. Antibacterial components are easy to precipitate, and the antibacterial effect cannot last

In addition, the existing antibacterial agents cannot simultaneously have antibacterial, anti-aging and health care functions. In order to achieve the anti-aging indicators required by plastic toys, adding antioxidants is an effective means to prevent oxidation of plastic toys

However, most of the known antioxidants are small molecular compounds with certain toxicity, which tend to gradually precipitate on the surface of plastic toys under the action of light, oxygen and heat, and are prone to failure and health and safety hazards.
