Abstract

The invention relates to a potato starch degradation plastic product which comprises the following ingredients by weight percent: 20%-40% of biological potato starch degradation master batch, 5%-10% of metallocene, 1%-3% of biological degradation accelerant, 0.1%-1% of photosensitizer, 1%-5% of PE wax, 30%-50% of LLDPE and 10%-20% of HDPE. By using the strength and the thermoplastic processing property of the biological starch master batch, the ingredients can be used for processing various kinds of film products, blow molding products and injection molding products in different adding amounts, and the products have strong degradation ability and wide range of application.

Description

technical field [0001] The invention relates to a degradable plastic product, in particular to a plastic product made of pure natural potato starch. Background technique [0002] Plastic, as a new material, has developed vigorously since the middle of the 20th century, and has shown a continuous growth trend year by year. Now, plastic products have been widely used in various industries and fields of human activities, and it is becoming more and more difficult to leave plastic products in our daily life. While the plastics industry is developing, plastic materials also encounter two problems: (1) limited resources. Polymer compounds such as plastics are mainly derived from petroleum, and petroleum is a non-renewable resource, which has been gradually depleted on the earth. (2) Pollution to the ecological environment. At present, the world's plastic production has reached 200 million tons, and my country's plastic production is also about 20 million tons per year.
