Novel PVC lubrication modifier

Abstract

The invention discloses a novel PVC (polyvinyl chloride) lubrication modifier. According to a formula, the modifier comprises the following components by weight: 30-50 parts of allene, 15-20 parts of allyl acetate, 10-30 parts of carbon fibers, 5-7 parts of malonic acid, 3-5 parts of phosphoric acid, and 4-5 parts of calcium silicate. The modifier provided in the invention can effectively increase the flowing property and plasticizing property of a PVC product, and increases weather resistance and impact resistance.

Description

technical field [0001] The invention relates to a modifier, in particular to a new PVC lubricating modifier. Background technique [0002] Because of the inherent molecular structure of polyvinyl chloride, when it is directly used as a raw material for extrusion processing to produce plastic products, its chemical properties have great defects, such as poor flexibility, brittleness, and poor impact resistance. Therefore, many additives, such as plasticizers, tougheners, anti-impact agents, lubricants, etc., should be added during the processing. However, due to the single function of the existing additives, multiple additives are often added to a PVC product, thus virtually increasing the cost of the product. Contents of the invention [0003] The purpose of the present invention is to provide a new type of PVC lubricating modifier aiming at the deficiencies of the prior art. [0004] In order to achieve the above object, the technical scheme adopted in the present inven...
