Problems solved by technology

However, the products it produces are fragile and have poor mechanical strength; and in order to achieve the purpose of waterproof and oil-proof, it is necessary to add a layer of inner coating on the product, which has not achieved complete environmental protection, and the production process is complicated

Abstract

The invention discloses a biodegradable tableware which contains the following components in weight percentage: 30-60% of starch, 2.5-7% of low-density polyethylene, 20-42% of polyethylene, 1-3% of polyethylene wax, 1-2% of glyceryl monostearate, 3-5% of ethylene-vinyl acetate copolymer, 1-3% of titanium white powder, 2-6% of light calcium carbonate, 1-3% of talc powder, 0.2-0.5% of Al-Ti composite coupler, 0.01-0.02% of modifier, 0.1-0.2% of anti-oxygen agent and 0.04-0.06 of antioxidant. The invention also discloses a method for processing the biodegradable tableware. The method comprises the steps of proportioning, mixing and melting at high speed, extruding and tabletting, molding under positive pressure, trimming and finishing, etc. The invention modifies the formulation and the corresponding production process, so that the biodegradable tableware is not fragile and has high mechanical strength. The biodegradable tableware has water-proof and oil-proof functions without needing inner coating, and can be degraded completely in a short degradation period.

Description

【Technical field】 [0001] The invention relates to disposable tableware, in particular to biodegradable environment-friendly tableware and a processing method thereof. 【Background technique】 [0002] Since the 20th century, with the rapid development of the petroleum industry and the chemical industry, plastics, with their good thermal properties and chemical stability, as a new type of material, have brought many conveniences to the industrial production and life of human society. Its use value has also been widely recognized. [0003] However, plastic products (such as: agricultural mulch, lunch boxes, packaging bags, beverage cups, shockproof materials, etc.) have serious pollution and damage to the natural environment and ecological environment, especially disposable plastic products, which are discarded after completing their functions. Discarded, it is difficult to degrade in a short time, and the environmental pollution is very serious. [0004] For this reason, peop...
