Abstract

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. Palm oil, a biomass resource, was used as raw material to synthesize palm fatty acid acrylamide ethyl ester and blend it with acrylic acid. Under the action of a photoinitiator, an environmentally friendly palm oil-based thermoplastic elastomer was prepared by digital light processing 3D printing technology. The palm oil-based thermoplastic elastomer prepared by the invention is environmentally friendly and has good tensile strength and tensile elongation at break.

Description

technical field [0001] The invention belongs to the technical field of polymer elastomer materials, in particular 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 high cost problem 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 manufacturing and applications. For example, with a global production of nearly 200 million tons, vegetable oil is a promising renewable resource for the production of low-cost, high-value bio-based elastomers. Palm oil is the largest vegetable oil in the world in terms of production, consumption and international trade. T...
