Abstract

The invention provides a biodegradable plastic cement material and a preparation method thereof. The material comprises polylactic acid, polymethyl methacrylate, polypropylene, dicapryl phthalate, butyl benzyl phthalate, castor oil, cocoanut fatty acid diethanolamide, cellulose, modified starch, butylated hydroxytoluene, butyl hydroxy anisd, polymethyl acrylate and silica. The preparation method comprises the steps of firstly, mixing, heating and stirring polylactic acid, polymethyl methacrylate, polypropylene, dicapryl phthalate, butyl benzyl phthalate, castor oil and cocoanut fatty acid diethanolamide, then adding the remaining components, conducting dispersion, then placing the mixture into a dryer for a reaction, and finally adding the mixture into a double-screw extruder for extrusion molding. The biodegradable plastic cement material can be degraded completely, is high in degradation speed and meanwhile has quite good elasticity and toughness.

Description

technical field [0001] The invention relates to the field of materials, in particular to a biodegradable plastic material and a preparation method thereof. Background technique [0002] As the population grows and people's living standards improve, our environment is also under tremendous pressure. On the one hand, our development cannot be stopped; on the other hand, we must also undertake the responsibility of improving the environment and trying not to cause pressure on the environment for development. Among them, the improvement and research and development of plastic materials have become the top priority. Our traditional plastic materials mainly pursue perfect performance, such as disposable plastics. Low, has caused very serious "white pollution", not only has an impact on the vision, but more importantly, it has also had a great impact on the living environment. Therefore, the research and development of environmentally friendly materials has become a research hots...
