Description

technical field [0001] The invention belongs to the technical field of polymer elastomer materials, and in particular relates to a digital light processing 3D printing palm oil-based thermoplastic elastomer and a preparation method thereof. Background technique [0002] Elastomers are widely used in industry and medicine. However, bio-based elastomers face many challenges, including high cost and low performance, which greatly limit their competitiveness in the market. The problem of high cost can be solved by using abundant and cheap biomass resources. In recent years, due to the high emphasis on renewable resources, many bio-based elastomers have been developed for fabrication and applications. For example, vegetable oil, with a global production of close to 200 million tons, is a promising renewable resource for the production of low-cost, high-value bio-based elastomers. Palm oil is the vegetable oil with the largest production, consumption and international trade in ...
