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 tarnish-resisting master batch. When color cable materials are secondarily processed, the tarnish-resisting master batch and the color cable materials are collectively added into a high blending machine to be uniformly mixed, then the mixture is extruded and granulated, a color PVC (polyvinyl chloride) product is consistent with the original color after being secondarily processed, an original product can be formed through the processing, and the cost is reduced. The tarnish-resisting master batch comprises PVC resin and plasticizer, and is characterized by also comprising titanium dioxide and purple pigment, wherein the weight ratio of each ingredient of the master batch is as follows: 100 parts of PVC resin, 30 to 70 parts of plasticizer, 10 to 100 parts of titanium dioxide, and 0.5 to 5 parts of purple pigment. All ingredients are uniformly mixed and extruded through an extruder to be granulated to obtain the tarnish-resisting master batch.

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...
