Abstract

The invention discloses a high-strength degradable plastic material. The plastic material is prepared from the following components in parts by weight: 30 to 40 parts of polyvinyl alcohol fiber, 25 to 30 parts of phenolic resin, 8 to 12 parts of polyvinyl acetate, 4 to 6 parts of chitosan, 9 to 13 parts of propylene glycol monomethyl ether, 2 to 5 parts of sodium oxamate, 7 to 11 parts of cellulose, 3 to 5 parts of dopamine hydrochloride, 6 to 10 parts of 2-mercaptoethanol, 1 to 3 parts of zinc sulfate heptahydrate, 2 to 5 parts of methyl vinyl ketone, 1 to 3 parts of polyvinyl pyrrolidone, and 5 to 8 parts of 1, 1, 3, 3-tetramethyldisiloxane. The plastic material has degradability, the subsequent processing cost of waste plastic materials is reduced, and the strength property of the plastic material is not reduced by the degradability, so that the plastic material can meet actual demands.

Description

technical field [0001] The invention belongs to the field of plastic materials, and in particular relates to a high-strength degradable plastic material and a preparation method thereof. Background technique [0002] In recent years, people's awareness of environmental protection has gradually increased, and healthy and green environmental protection has become the main development trend. The wide application of plastic materials provides great convenience to our life and improves the quality of life, such as the construction of plastic runways. With the full development of our national fitness, the plasticization of sports venues has become a hardware requirement for major sports venues and fitness venues. In addition to the plastic runway, there are many other convenient applications of plastic materials; however, we must also consider how to recycle and utilize traditional plastic materials after they reach the end of their service life, and how to deal with waste plasti...
