Problems solved by technology

[0002] At present, the main components of various plastic toys on the market are PVC (polyvinyl chloride), PE (polyethylene), PP (polypropylene), ABS (acrylonitrile-butadiene-styrene copolymer), etc., all of which are petrochemical The products are all high polymers. Due to the high degree of polymerization and strong intermolecular forces, the polymer chains are difficult to break and decompose, which leads to the non-degradability of existing plastic toys and pollutes the environment.
The processing methods mainly include injection molding and extrusion molding. The material temperature is usually controlled at 150-250°C during processing. At the same time, petroleum is a non-renewable resource on the earth, which makes petroleum products non-renewable and expensive.

Embodiment 1

[0032] According to the weight ratio of each component, 100 parts by weight of biodegradable masterbatch BM1150, 50 parts of resin PP, filler CaCO 3 Add 30 parts into the low-speed mixer one by one at room temperature and stir for 5 minutes, then add 2 parts of dispersant, 1 part of lubricant, 0.2 parts of nucleating agent, 2 parts of coupling agent, and 5 parts of coloring agent, and stir for 10 minutes. A blend is obtained. The blended material is poured out and placed in a vertical hopper dryer (revolving hot air type) for drying. The drying time is 2 hours, the air volume is 1850 cubic meters per hour, the air pressure is 1350Pa, and the temperature is controlled at 110°C±2°C. Put the dried blend into the injection machine for injection molding, the injection pressure is 150±1Mpa, the clamping force is 735KN, the barrel temperature of the injection machine is 160°C in the front section, 170°C in the middle section, and 180°C in the back section. Trimming, assembling, col...
