Problems solved by technology

In this way, the product structure of the external slip agent is relatively simple, the product performance is single, and the product is prone to precipitation.
As a result, the melt strength is reduced during the processing, the processing is not easy to be plasticized, the production efficiency is reduced, the production is inconvenienced to the customer, and the production cost is increased.

Abstract

The present invention relates to a PVC external lubricant, including: 30-70% of vegetable oil acid, 5-12% of epoxy oleic acid, 7-9.5% of diethylene glycol, 4-6% of adipic acid, 20-30% of pentaerythritol, 0.2-0.5% of phosphoric acid, and 0.2-0.8% of butyl titanate. The content of adipic acid is 5.5%. The content of phosphoric acid is 0.3%. The epoxy group of the epoxy oleic acid in the PVC lubricant of the present invention is chemically reactive, and can react with hydrogen chloride to absorb the hydrogen chloride, thereby preventing PVC plastic from accelerated aging and making a stabilizing effect.

Description

technical field [0001] The invention relates to a polyvinyl chloride processing aid, in particular to a polyvinyl chloride external lubricant. Background technique [0002] At present, PVC external lubricants mainly use polyols, stearic acid, adipic acid, etc. as the main raw materials, and the external lubricants are obtained through esterification. In this way, the product structure of the external slip agent is relatively simple, the product performance is single, and the product is prone to precipitation. As a result, the melt strength is reduced during the processing, the processing is not easy to be plasticized, the production efficiency is reduced, the production of the customer is brought inconvenience, and the production cost is increased. Contents of the invention [0003] The technical problem to be solved by the invention is to provide a polyvinyl chloride external lubricant with good compatibility and dispersibility. [0004] In order to solve the ab...
