Description
NOVEL COMPOSITE BIODEGRADABLE PLASTIC MATERIAL FOR LUS01424
[01] The present invention belongs to the technical field of biodegradable materials, and in particular relates to a novel composite biodegradable plastic material for injection molding and a preparation method therefor.
[02] Rubber injection molding, plastic injection molding and forming injection molding are common methods for producing injection molding products. The plastic injection molding is a method for manufacturing plastic products. Presently, the plastic injection molding generally includes injecting molten polyethylene, polypropylene, acrylonitrile butadiene styrene (ABS), polyamide (PA), polystyrene and other plastic materials into a plastic product mold by pressure and then cooling a mixture to obtain a plastic product. However, the plastic materials feature poor degradability and pose intensive pressure on the environment, therefore, the research of biodegradable composite materials is the main research direction of the modern plastic industry. Poly(butyleneadipate-co-terephthalate) (PBAT) (a copolymer of butylene adipate and butylene terephthalate), a thermoplastic biodegradable plastic, is one of active degradable materials with optimal market applications in the research of biodegradable plastics. However, existing PBAT products are single in type but high in price. Moreover, the PBAT has a low melt index (MI) and high intrinsic viscosity, making it unsuitable for direct use in injection molding process. When being applied for manufacturing large-area PBAT injection molding products, especially large-area thin-walled flexible products, the PBAT is very prone to short shot, mold sticking and other phenomena, resulting low yield and production efficiency.
[03] CN108102318B discloses a biodegradable film material. A biodegradable material is composed of any one or more of groups consisting of polylactic acid (PLA), PBAT and poly(butylene succinate) (PBS), with a content of 60-70 mass percent. Food-grade agricultural waste is powder generated after fine grinding of starch, fibers, protein or lipid, and a particle size of the food-grade agricultural waste after grinding and drying is at least SOum, with a content of 10-30 mass percent. A film material is made through steps such as mixing, blowing and coating. A blown film is biodegradable, However, still has the disadvantages of mold sticking, short shot and low productivity.
[04] CN108329529A discloses a completely-biodegradable copolymerized extruded sheet raw material, which includes PLA, PBAT, PBS, plant starch, straw cellulose, a filler, a plasticizer and an antioxidant. A preparation method is an extrusion process, which produces plastic sheets with a desirable degradation effect, are incapable of causing secondary pollution, and have high temperature resistance and low temperature resistance, but has high cost.
