Environment-friendly plasticizer for plastic and preparation method of plasticizer

Abstract

The invention provides an environment-friendly plasticizer for plastic and a preparation method of the plasticizer. The environment-friendly plasticizer for plastic is prepared from raw materials in parts by weight as follows: 10-30 parts of epoxidized soybean oil, 10-20 parts of dodecylbenzene, 5-20 parts of triethanolamine oleate, 20-30 parts of tricresyl phosphate, 5-10 parts of tributyl citrate, 3-5 parts of polyvinyl chloride, 3-5 parts of diethylene glycol diphthalate, 2-5 parts of polyethylenimine, 1-2 parts of ethylene glycol monobutyl ether, 3-5 parts of zinc stearate and 1-5 parts ofa binder. The plasticizer is high in plasticization efficiency, resistant to cold, heat, pollution and drawing, good in mobility, high in electrical insulation property and environmentally friendly.A novel plasticizer product is obtained after multiple plasticizers are compounded and mixed to endow resin products with good comprehensive performance, and the satisfying plasticization effect is realized.

Description

technical field [0001] The invention relates to the technical field of environmental protection technology, in particular to an environmentally friendly plasticizer for plastics and a preparation method thereof. Background technique [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. Among them, DEDB pla...

AI Technical Summary

Problems solved by technology

Among them, DEDB plasticizer has large molecular weight and molecular polarity, good compatibility with PVC resin, high plasticizing efficiency, good pollution resistance and durability, but its melting point is low, it is solid in winter, and it is inconvenient to use

DOTP is an isomer of DOP. Due to the difference in structure, it has better electrical resistance, heat resistance, extraction resistance, and migration resistance than DOP, but its plasticizing performance is lower than DOP.

Other plasticizers such as epoxies, aliphatic polybasic esters, trimellitates, etc., all have their own unique properties, but they have not been widely used due to their poor compatibility with resins.
