Abstract

The invention discloses a polyvinyl chloride (PVC) multipurpose inner lubricant. The multipurpose inner lubricant comprises high alcohols, catalysts, color modifiers and phthalic anhydride. The high alcohols are composed of octadecanol and hexadecanol. The feeding weight ratio of the high alcohols and phthalic anhydride is 3.54-3.9:1. Compared with the prior art, the multipurpose inner lubricant has characteristics of speeding fusion, lowering the fusion viscosity, prolonging the processing life, improving fluidity, raising transparency and the like. The multipurpose inner lubricant has excellent compatibility with polyvinyl chloride, thus hard and soft PVC products achieve excellent thermal stability and transparency, safety, non-poison and environmental protection are achieved, and the multipurpose inner lubricant can be used in cooperation with stable systems of organic tin, calcium / zinc, barium / cadmium and lead salt and the like, has supper additive effect effects and raises the combination properties.

Description

technical field [0001] The invention relates to the technical field of polyvinyl chloride plastic processing, in particular to a polyvinyl chloride (PVC) universal internal lubricant. Background technique [0002] Lubricants are an important class of additives in plastic processing, and can be called "catalysts" for plastic processing. At present, there are few varieties of ester lubricant products in PVC plastic processing, there is not much room for selection, the technical content of product performance is not high, and the lubricating performance of lubricants is not ideal. At present, there is no or very few ester lubricants with both internal and external lubricity, stability and synergy in this field. PVC plastic processing enterprises urgently need high-quality lubricant products to meet the market demand for high-grade plastic products. Contents of the invention [0003] The purpose of the present invention is to provide a polyvinyl chloride (PVC) universal inte...
