Abstract

The high-concentration white polyolefin agglomerate consists of pigment, plastic assistants and carrier resin, nd the plstic assistants include polyvinyl wax, zinc stearate, bright lubricant, compatibilizer-bulking material, crosslinking agent and liquid paraffin. The preparation process includes mixing via high speed stirring, extruding the mixture in a double-screw extruder, cooling, stoving, and pelletizing. The present invention has the features of high whiteness, low consumption, high dispersivity, etc., and is suitable for plastic product with polyethylene, polypropylene or their copolymer as basic material and suitable for injection molding, blowing to film, hollow forming and extruding to produce sheet, flat belt, wire and pipe.

Description

Technical field [0001] The invention relates to the technical field of plastic coloring, in particular to a high-concentration white master batch for polyolefin plastic coloring and a preparation method thereof. [0002] The invention also relates to a preparation method of the polyolefin plastic white masterbatch. Background technique [0003] The existing white masterbatch increases the cost of the product because of its low concentration and high addition amount. In particular, this kind of masterbatch has a certain selectivity to the base material of the product. If the base material is not selected properly, it will often affect the mechanical properties and printing performance of the product. The currently used high-concentration white masterbatch for polyolefins has strong market competitiveness due to its high concentration of white pigments, high performance-price ratio, and greatly reduced production costs. However, the main disadvantages of this kind of masterb...
