[0003] Because the production of thermoplastic elastomers consumes a lot of oil, it causes the crisis of excessive use of limited energy on the earth. At the same time, in the production and application of PVC elastomers, it also brings serious harm to the living environment of human beings.
According to relevant data, a large amount of harmful solvents such as plasticizers (such as dioctyl phthalate, dibutyl phthalate, etc.) need to be used in the production of PVC. The harmful gases generated by these solvents enter the atmosphere and cause environmental pollution. , life-threatening health

Abstract
The invention discloses biomass-based thermoplastic elastic master batch. The biomass-based thermoplastic elastic master batch is prepared, by weight, by the following raw materials of 50-70 parts of biological powder, 5-10 parts of biolipid, 3-8 parts of plant fibers, 8-20 parts of polyurethane, 4-10 parts of hide glue, 8-20 parts of capacity-increasing plasticizer, 0.5-5 parts of grafting coupling agents and 0.5-5 parts of functional auxiliaries. According to the biomass-based thermoplastic elastic master batch and a preparation method thereof, the biomass-based materials such as the biological powder, the biolipid and the plant fibers are adopted to serve as the main raw materials to prepare the elastomer material, screening and optimizing are conducted on the biomass-based material, the preparation technologies such as modification and crosslinking copolymerization are combined, and the prepared biomass-based thermoplastic elastic master batch has better biodegradability. Sources of the selected raw materials are rich, the cost is low, consumption of petroleum can be effectively reduced, and the biomass-based thermoplastic elastic master batch is environmentally friendly; the forming technologies are combined by adopting general processing equipment, and industrialized application and popularization are convenient.
Description
Technical field [0001] The invention belongs to the field of biodegradable materials (new materials), and specifically relates to a biomass-based thermoplastic elastic masterbatch and a preparation method thereof. Background technique [0002] At present, there are mainly two types of thermoplastic elastomer materials in my country, one of which is styrene-butadiene (SHS, SEBS, etc.) series; the other is polyvinyl chloride (PVC, etc.) series. [0003] The production of thermoplastic elastomers needs to consume a lot of oil, causing a crisis of excessive use of limited energy on the earth. At the same time, in the production and application of PVC elastomers, it also brings serious harm to the human living environment. According to relevant data, plasticizers and other harmful solvents (such as dioctyl phthalate, dibutyl phthalate, etc.) need to be used in large quantities in the production of PVC. The harmful gases generated by these solvents enter the atmosphere and cause environm...
