Description

technical field [0001] The invention belongs to the field of chemical industry, and in particular relates to a plasticizer. Background technique [0002] Any substance added to the polymer system that can increase the plasticity of the polymer system can be called a plasticizer. Among the plasticizers, phthalate plasticizers are used in the largest amount, accounting for more than 50% of the plasticizers. market share. However, because of its high volatility and pathogenic factors, many countries have banned the use of children's toys and child care products, and the scope of use is limited. Therefore, people are seeking and researching alternatives to phthalate plasticizers to find an environmentally friendly new plasticizer. Contents of the invention [0003] The invention provides an environmentally friendly novel plasticizer, and therefore, the invention also provides a preparation method of the novel plasticizer. [0004] In order to achieve the above o...
