Problems solved by technology

There are toys made of plastics such as ABS, PE, PVC, POM, EVA resin, nylon, unsaturated polyester, and thermoplastic elastomer. The waste is difficult to degrade in the environment, and it is difficult to deal with. Landfill and incineration are not ideal. Pollution has become a global problem
[0003] In addition, some children's plastic toys used for teaching, because the teaching environment is indoors, the air circulation is poor, and a large number of children gather together, which will further deteriorate the air quality, which is not conducive to children's physical and mental health

Abstract

The invention discloses a child teaching toy with an air purifying function and a preparation method thereof. The child teaching toy is prepared from the following raw materials: tourmaline powder, modified plant starch, acrylic acid, 2,5-dimethyl-2,5 ditert-butyl hexane peroxide, ABS (Acrylonitrile Butadiene Styrene) resin, a silane coupling agent, polyethylene glycol, calcium carbonate, bentonite powder, methylsilicone oil and a photo degradation agent. The preparation method comprises the following steps that (1) tourmaline powder is pre-treated for stand-by application; (2) modified plantstarch grafted polyacrylic acid / tourmaline powder composite resin is prepared; (3) main materials are prepared; (4) accessory materials are prepared; and (5) the main materials and the accessory materials are mixed, the photo degradation agent is added, an obtained mixture is fused, mixed and extruded out through a twin-screw extruder, and the child teaching toy can be produced through injection molding. The prepared child teaching toy is simple in preparation technology; the produced toy is free of toxicity and environmentally friendly, has the effect of purifying the air, can effectively improve the air quality of the child teaching environment, and is beneficial for physical and mental health of children.

Description

Technical field [0001] The invention belongs to the field of children's toy processing technology, and specifically relates to a children's teaching toy with the function of purifying air and a preparation method thereof. Background technique [0002] The toy industry is a world-wide industry. About 70% of the world's toys are manufactured in China, and most of them are plastic products. However, the development of the plastic toy industry will face two major problems: one is the source of raw materials, and the other is pollution. As the total amount of global oil continues to decrease, the price of plastic resins using petroleum as raw materials has been high and is facing the danger of exhaustion. There are toys made of ABS, PE, PVC, POM, EVA resin, nylon, unsaturated polyester, and thermoplastic elastomers. The waste is difficult to degrade in the environment, and it is difficult to deal with. Landfill and incineration are not ideal. Pollution has become a global problem. ...
