Abstract

The invention relates to a tung oil hyperbranched polyester plasticizer as well as a preparation method and application thereof. Tung oil is used as a raw material and is subjected to alcoholysis reaction with glycerol under the catalysis of alkali to obtain tung oil-based hyperbranched polyol, then the tung oil-based hyperbranched polyol is subjected to epoxy ring-opening reaction with glycidol under the catalysis of alkali to synthesize tung oil-based hyperbranched polyol, and finally, the tung oil-based hyperbranched polyol is directly subjected to esterification reaction with anhydride tosynthesize the tung oil hyperbranched polyester plasticizer. A tung oil hyperbranched polyester plasticized PVC material is prepared by methods of solvent casting, thermoplastic blending and the like.According to the method, the glass-transition temperature of the PVC product can be reduced to 32.9 DEG C.

Description

technical field [0001] The invention belongs to the technical field of chemical synthesis, and in particular relates to a tung oil hyperbranched polyester plasticizer and a preparation method and application thereof. Background technique [0002] Polyvinyl chloride (PVC) is one of the most used plastics in the world and is widely used in construction materials, medical equipment, household appliances and other fields. Due to the strong interaction between polyvinyl chloride molecular chains, a large amount of plasticizer needs to be added during processing to reduce the interaction between macromolecular chains, so as to improve the processing performance and soften the product. At present, the production capacity of plasticizers in my country has reached 4.5 million tons, of which the output of ortho-benzene plasticizers accounts for about 80% of the total plasticizer output, and the usage of ortho-benzene plasticizers in European and American countries accounts for 65% of ...
