Abstract

The invention belongs to the technical field of polymer elastomer materials, and particularly relates to a 3D printing inorganic salt reinforced palm oil-based high-performance elastomer and a preparation method thereof. A bio-based palm oil-based monomer and acrylic acid are used as raw materials, inorganic salt particles are used as a reinforcing material, and the palm oil-based high-performanceelastomer is obtained through a digital light treatment 3D printing technology under the action of a photoinitiator. The prepared palm oil-based high-performance elastomer is environment-friendly andhas good tensile strength and tensile elongation at break.

Description

technical field [0001] The invention belongs to the technical field of polymer elastomer materials, and in particular relates to a 3D printing inorganic salt-reinforced palm oil-based high-performance 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...
