Spherical color master batch particles and casting process thereof

Abstract

The invention discloses a spherical color master batch particle and a casting process thereof, and belongs to the technical field of color master batch preparation, the preparation process of the spherical color master batch particle comprises the following steps: raw material proportioning and weighing, raw and auxiliary material stirring and mixing, pigment preheating, pre-material melting and mixing, color master batch brace shearing, double-wheel extrusion granulation, and dividing of the strip-shaped color master batch into a plurality of spherical color master batch particles under extrusion forming of the double wheel discs; the manufactured block-shaped color master batch can be processed, the block-shaped color master batch is decomposed into the spherical color master batch particles under the condition that the color matching state of the color master batch is not changed, so that in the processing processes such as dyeing of plastic products, the reaction area with a reaction substrate is increased, mixing of the color master batch and the reaction substrate is accelerated, the color master batch can be better mixed with a plastic product, the dyeing effect and speed ofthe color master batch on the plastic product are improved, and the quality of the formed product is improved.

Description

Technical field [0001] The present invention relates to the preparation of color masterbatch, and more particularly to a spherical-shaped mother particles and a casting process. Background technique [0002] The full name of the color mother is called color masterbatch, also called a color, is a new type of polymer material, which is also known as the pigment preparation. Colormother is mainly used on plastics. The color mother consists of three basic elements of pigments or dyes, carriers, and additives. It is the aggregate obtained by uniformly carrying the superomal amount of pigments, which can be called a pigment concentrate, so it has higher colummetic strength. The pigment itself. The coloring resin or article of the design pigment concentration can be achieved with a small amount of color masterbatch and the unsatisfactory resin during processing. [0003] The basic component of the color mother has a pigment, carrier, dispersant, and additive to make the pigment to refin...

Problems solved by technology

[0005] Although the above technical solution can industrially produce color masterbatch through a relatively simple process, the color masterbatch produced is a large block color masterbatch. In the process of being put into use, due to the large volume of the formed block color masterbatch, it cannot be quickly Dispersed in the material to be processed, so that the color distribution of the processed material is uneven, affecting the quality of the product after molding
