Problems solved by technology

In most cases, PVC products need secondary processing due to poor plasticization, moisture, etc., and the secondary granulation process of colored products will cause discoloration of the newly prepared colored cable materials due to the decomposition of a small amount of polyvinyl chloride. method does not work around this discoloration
The discolored cable material cannot be used again because the color is inconsistent with the original one, so the colored PVC cable material cannot be processed into the original product twice, which requires additional new materials to manufacture colored soft PVC cable material, which is costly

Abstract

The invention discloses an anti-discoloration masterbatch, which is mixed with the colored cable material in a high-mixer when the colored cable material is subjected to secondary processing, and then extruded and granulated to ensure that the colored PVC product is compatible with the color PVC product after secondary processing. The original color is consistent, and the original product is processed to reduce the cost. It includes PVC resin and plasticizer, and is characterized in that: it also includes titanium dioxide and purple toner, and its mass ratio is as follows: PVC resin: 100 parts; plasticizer: 30-70 parts, titanium dioxide: 10 parts- 100 parts; purple toner: 0.5 to 5 parts; obtained by extruding and granulating through an extruder after mixing the above-mentioned ingredients uniformly.

Description

technical field [0001] The invention relates to the technical field of processing soft polyvinyl chloride cable materials, in particular to an anti-discoloration masterbatch, and the invention also provides a manufacturing method of the anti-discoloration masterbatch. Background technique [0002] The usual practice of existing colored flexible PVC cable materials is to add various toners or color masterbatches in addition to conventional materials to make colored products. In most cases, PVC products need secondary processing due to poor plasticization, moisture, etc., and the secondary granulation process of colored products will cause discoloration of the newly prepared colored cable materials due to the decomposition of a small amount of polyvinyl chloride. method cannot solve this discoloration problem. The discolored cable material cannot be used again because the color is inconsistent with the original one, so the colored PVC cable material cannot be processed into t...
