Abstract

The invention relates to the technical field PVC resin auxiliaries, in particular to a PVC resin oil-soluble terminator and a preparation method thereof.The PVC resin oil-soluble terminator is prepared from, by weight, 5-50 parts of epoxidized soybean oil, 10-30 parts of an antioxidant, 10-40 parts of bisphenol A, 1-20 parts of a solid terminator, 5-40 parts of a stabilizer, 1-40 parts of a plasticizer, 5-45 parts of styrene, 5-25 parts of solvent oil and 5-40 parts of a methanol solution.The obtained PVC resin oil-soluble terminator is good in termination effect and long in heat stabilization time; solid materials are added into a reaction kettle at a time in the preparation process, reaction time is greatly shortened, the reaction temperature is low, energy consumption is reduced, and the productivity of a production device is improved; no wastewater is generated in the whole production process, the production technology is environmentally friendly, and the equipment requirement of the technology is low; a production system is safe and stable in operation and has good economic benefits.

Description

technical field [0001] The invention relates to the technical field of PVC resin additives, and relates to a PVC resin oil-soluble terminator and a preparation method thereof. Background technique [0002] In the process of producing polyvinyl chloride by suspension method, for safety, when the late stage of polyvinyl chloride polymerization drops to the specified pressure or abnormality occurs, a terminator must be added to the polymerization reactor to terminate the monomer in the reactor and the pipeline to continue polymerization reaction, so that it immediately terminates the polymerization reaction. The quality of the terminator directly affects the progress of the termination reaction and the final product of polyvinyl chloride. At present, various terminators are used in the production of PVC resin in China. The Chinese patent document with publication number 103288988A discloses a preparation method of a styrenated bisphenol A derivative as a polyvinyl chloride ter...
