Problems solved by technology

[0002] In addition to directly mixing dry powder for PVC coloring, generally, slurry pigments can also be used, that is, pigments and plasticizers are ground into a slurry in a certain proportion, and then mixed with resins and additives for molding processing, but the effect is not good.

Embodiment Construction

[0011] The present invention will be further described below.

[0012] PVC black masterbatch of the present invention is used for PVC cable material, and its composition by mass parts is:

[0013]

[0014] The plasticizer is a mixture of pentaerythritol esters and trioctyl trimellitate;

[0015] Described stabilizer is zinc stearate;

[0016] Dispersant A is white oil;

[0017] Dispersant B is a mixture of polyethylene wax homopolymer and ethylene-vinyl acetate copolymer wax.

[0018] The process flow is as follows: Dispersant A, pigment black, carbon black, and plasticizer are first ground; then mixed with stabilizer, dispersant B, carrier polyvinyl chloride and other additives, and stirred in a high-speed kneader; finally Extruder granulation.

[0019] The addition amount of the masterbatch in PVC resin is 3-5 parts.

Abstract

The invention mainly relates to the field of polymer materials, especially relates to a polymer material functional master batch, and especially relates to a PVC black master batch. The PVC black master batch comprises following components in parts by weight. The black master batch having the above formula has good compatibility with PVC resin, good dispersibility, good heat stability, fluidity, good transference resistance, and other indexes.

Description

technical field [0001] The invention mainly relates to the field of polymer materials, in particular to a functional masterbatch of polymer materials, especially a PVC black masterbatch. Background technique [0002] In addition to mixing directly with dry powder for PVC coloring, generally, slurry pigments can also be used, that is, pigments and plasticizers are ground into a slurry in a certain proportion, and then mixed with resins and additives for molding processing, but the effect is not good. For PVC color masterbatch, there are few manufacturers, which is mainly due to the high viscosity of PVC color masterbatch and easy decomposition. Contents of the invention [0003] The object of the present invention is to provide a kind of PVC black masterbatch, the compatibility, dispersibility, thermal stability, fluidity, migration resistance and other indicators of the color masterbatch and PVC resin are all good, its coloring is uniform, and the color is bright , and do...
