Description

technical field

[0001] The invention relates to a chemical plasticizer and a preparation method, which can be used as an environment-friendly composite plasticizer as the main plasticizer of polyvinyl chloride (PVC) and other resins. technical background

[0002] Plasticizers are the largest additives in the modern plastics industry, accounting for 60% of the total output of plastic additives. Among them, phthalates as plastic plasticizers account for more than 50% of the market share of plasticizers. Dioctyl phthalate (DOP), as the main plasticizer, was suspected of carcinogenicity by the National Cancer Institute (NCI), and its use was restricted. People are looking for and researching alternatives that are safer and perform better than DOP. Diethylene glycol dibenzoate (DEDB) and bis(2-ethylhexyl) terephthalate (DOTP) are the two most common environmentally friendly plasticizers, which can replace DOP as the main plasticizer , has the value of promotion and application....
