Problems solved by technology

However, since cellulose is a polyhydroxy compound with certain water absorption, it is prone to incompatibility with hydrophobic PBAT, which will lead to a decrease in mechanical properties, and the use of coupling agent modification will lead to cost reduction. Greatly provided, not conducive to industrial production

Abstract

The invention relates to the technical field of simulation materials, in particular to a fully degradable simulation material and a preparation method thereof. The fully degradable simulation materialincludes PBAT, plant fiber powder, mineral powder, a biodegradation promoter, a lubricant and an antioxidant. According to the invention, PBAT is adopted as the matrix resin, mineral powder is takenas the main modified filler, and plant fiber powder is used as the minor modified filler to effectively improve the tensile properties and impact resistance of the simulation material, also after adding of the biodegradation promoter, the degradability of the simulation material can be improved, and under the condition of natural degradation, carbon dioxide and water can be generated eventually toparticipate in plant photosynthesis. The simulation material not only has no pollution to the environment, but also can achieve a full degradation effect, and the 1y degradation residual weight can be reduced to 13.4% or less.

Description

technical field [0001] The invention relates to the technical field of simulation materials, in particular to a fully degradable simulation material and a preparation method thereof. Background technique [0002] The problems of environmental degradation and resource shortage in the world are becoming more and more prominent, and the pollution of the environment by ecological solid waste and the waste of resources caused by it are becoming more and more serious. With the continuous improvement of economic development and people's living standards, the discharge of solid waste has increased sharply. It is estimated that the world adds about 10 billion tons of solid waste every year, or 2 tons per capita. The increasing solid waste has brought great challenges to the human living environment and has become one of the main factors of environmental pollution. [0003] PBAT is a thermoplastic biodegradable plastic, which is a copolymer of butylene adipate and butylene terephtha...
