Problems solved by technology

The prior art (CN201480071441.9) provides a preparation method of biodegradable polyester resin, which mainly prepares a kind of effective biodegradable polyester resin through dicarboxylic acid, diol, catalyst and deactivator that can reduce catalyst activity. Degradable polyester resin materials, but lack of related modification or addition of rigid monomers, can not effectively improve the toughness and mechanical properties of degradable polyester resin materials, greatly reducing the application field of polyester materials and environment

Abstract

The invention discloses a high-toughness polyester resin material and a preparation method thereof. The high-toughness polyester resin material at least comprises the following raw materials in parts by weight: 30-50 parts of dihydric alcohol, 70-90 parts of binary acid, 10-20 parts of carboxylic acid monomer, 8-10 parts of an auxiliary agent, 10-20 parts of elastic particles and 5-10 parts of a catalyst, and the elastic particles are at least one of polymer elastomer particles. The high-toughness polyester resin material prepared in the invention has good rigidity, mechanical properties and chemical resistance, effectively enhances the toughness of a polyester elastomer, is suitable for popularization in the field of polyester resin, and has a wide development prospect.

Description

Technical field [0001] The present invention relates to the C08G field, in particular to a highly ductile polyester resin material and a preparation method thereof. Background [0002] With the progress of society and economic development, as well as increasing environmental pressures, prompting people to gradually pay more and more attention to degradable green materials, especially in recent years, the research and development of degradable polymer materials has attracted widespread attention in the field of materials. [0003] In particular, the research on degradable polyester resin materials has also become the focus of attention in the polymer materials community in recent years. Prior art (CN201480071441.9) provides a biodegradable polyester resin preparation method, which is mainly through dicarboxylic acids, glycols, catalysts and deactivating agents that can reduce catalyst activity to prepare a biodegradable polyester resin material, but its lack of related modified or...
