Environment-friendly degradable material based on nanometer modifier

Abstract

The invention brings forward an environment-friendly degradable material based on a nanometer modifier. The material of the invention comprises the following raw materials (by weight): 40-80 parts of starch, 20-40 parts of cellulose, 10-20 parts of pectin, 5-12 parts of a nanometer modifier, 5-8 parts of dimethyl siloxane, 35-80 parts of polyvinyl chloride, 1-4 parts of a cross-linking agent, 0.5-1.0 part of phthalic acid di(2-ethylhexyl)ester, 0.3-0.8 part of diisononyl phthalate, and 0.3-0.6 part of a photosensitizer. Through reasonable blending of the above formula, the prepared degradable material has good wear resistance and long service life, and is degraded rapidly when discarded. Part of degraded product can be recovered, and the residual product is environment-friendly. Thus, the material is an environment-friendly degradable material. In addition, a preparation method of the material is simple, is easy for industrial production, and is worthy of promotion.

Description

technical field [0001] The invention relates to the technical field of material chemistry, in particular to an environmentally friendly and degradable material based on a nano-modifier. Background technique [0002] Plastic bags are essential items in people's daily life and are often used to hold other items. It is widely used because of its low cost, extremely light weight, large capacity, and easy storage, but it is banned from use and production in some countries because of the extremely long degradation cycle and difficult disposal of plastic bags. Since June 1, 2008, China has implemented a plastic restriction order: "In all supermarkets, shopping malls, bazaars and other commodity retail places, a system of paid use of plastic shopping bags will be implemented, and plastic shopping bags will not be provided free of charge. The production, sale, and use of plastic shopping bags with a thickness of less than 0.025 millimeters are prohibited." The main purpose of imple...

Problems solved by technology

However, due to the poor abrasion resistance of the existing degradable plastic bags, they will be damaged and abandoned after being used for less than three months. These abandoned plastic bags cannot be completely degraded in a short period of time, so these plastic bags often Pile together with garbage, which reduces the contact between plastic bags and the outside world, makes the degradation effect of plastic bags not obvious, slows down the degradation speed, and accumulates with garbage for a long time will occupy a lot of ground space
