Abstract

The invention belongs to the technical field of biodegradable materials and particularly relates to a degradable thermoplastic rubber membrane and a preparation method thereof. The degradable thermoplastic rubber membrane using agricultural plant resources as a main material is characterized in that the degradable thermoplastic rubber membrane is prepared from the raw materials including plant skins and shells, vegetable fibre, plant-based powder, polymer, compatibilizer and plasticizer and functional additive, wherein raw materials comprise the following components by weight percent: 5-15% of plant skins and shells, 4-10% of vegetable fibre, 30-70% of plant-based powder, 3-7% of polymer, 17-40% of compatibilizer and plasticizer and 1-5% of functional additive; the functional additive is one of an odor absorbing agent, an insect-resist agent, preservative and a defoaming agent or a mixture including any two or more agents, and the mixture can be arbitrary ratio when being mixed with any two or more agents. The degradable thermoplastic rubber membrane provided by the invention not only has the physical mechanization functions of rubber and plastic but also the comprehensive function of ordinary rubber and plastic; in addition, the degradable thermoplastic rubber membrane prepared by the method provided by the invention has the characteristics of low cost and capability of biodegradation.

Description

technical field [0001] The invention belongs to the technical field of biodegradable materials, and in particular relates to a degradable thermoplastic rubber film and a preparation method thereof. Background technique [0002] Using agricultural plant resources to make degradable materials as the main raw materials to replace plastic packaging products, making agricultural plant materials a new alternative to petroleum-based resources, not only giving agricultural plants new economic value, improving the economic benefits of agricultural production, To reduce the waste of limited resources (such as oil), but also to control the environmental "white pollution" caused by the extensive use of plastic packaging products. [0003] From the perspective of the development technology of biodegradable materials, using natural polymer materials and polymer derivatives as the main raw materials to produce degradable materials with superplastic function is the main direction of current...
