High-dispersity black polyethylene color master batch

Abstract

The invention discloses a high-dispersity black polyethylene color master batch which is composed of the following components in parts by weight: 35 parts of carbon black, 43 parts of polyethylene, 20 parts of calcium carbonate, 1 part of zinc stearate and 1 part of stearic acid. The high-dispersity black polyethylene color master batch has favorable dispersity, can be applied to a flow casting or film spraying technique, and can also be applied to foamed products. When being applied to the flow casting or film spraying technique, the color master batch has the advantages of high dispersity and favorable color developing property, so that the film product is blacker and has favorable glossiness, thereby lowering the production of defectives. When the color master batch is applied to the foamed products, the foaming products have the advantages of no toner spot hole and uniform color darkness.

Description

technical field

[0001] The invention relates to a highly dispersed black polyethylene color masterbatch. Background technique

[0002] Black polyethylene masterbatch uses carbon black as the pigment, and uses the heating, plasticizing, stirring, and shearing effects of the granulator to fully combine the pigment molecules with the polyethylene carrier resin to make the color of the resin particles. Masterbatch.

[0003] Black polyethylene masterbatch is used in laminating process, often there will be poor dispersion, insufficient blackness and glossiness, etc., resulting in surface defects of products, for example: 1) Black polyethylene masterbatch is applied to braided belt lamination, if the color If the dispersion of the masterbatch is not good, the casting film will not disperse, and the surface of the braid product will have defects of white leakage; in addition, due to the poor dispersion of the masterbatch, the concentration of the pigment color cannot be fully displ...
