Problems solved by technology

[0004] The above existing technical solutions have the following defects: the main components of the color masterbatch in the prior art are carrier resin, pigment and dispersant. Although the dispersibility of the color masterbatch is very good, the functionality of the color masterbatch is relatively single , the carrier resin in the raw material of the color masterbatch is usually a flammable organic substance, and the preservation and use of the color masterbatch need to be controlled under the conditions of fire prevention and high temperature, which makes the color masterbatch have certain limitations

Abstract

The invention discloses a production process for flame-retardant color masterbatches, and relates to the technical field of color masterbatches. The production process comprises the following processsteps: S1, batching: a step of weighing the following raw materials in parts by weight: 40-60 parts of carrier resin, 10-20 parts of a pigment and 1-3 parts of a dispersing agent, wherein the carrierresin comprises, in percentages by weight, 50-60% of ABS resin and 40-50% of a flame-retardant filling material; S2, mixing: a step of crushing the carrier resin, then adding the dispersing agent, carrying out stirring for 40-50 min, adding the pigment, and carrying out stirring for 30-40 min; and S3, extrusion: a step of adding the raw materials mixed in the step S2 into a twin-screw extruder, and carrying out extrusion and granulation. The flame-retardant color masterbatch product is obtained by adopting the above-mentioned three steps. The preparation method provided by the invention has the advantage of improving the flame retardance of the color masterbatches.

Description

technical field [0001] The invention relates to the technical field of preparation of color masterbatches, in particular to a production process of flame-retardant color masterbatches. Background technique [0002] The full name of color masterbatch is color masterbatch, also called color seed, which is a new type of special colorant for polymer materials, also known as pigment preparation. Color masterbatches are mainly used in plastics. The color masterbatch is composed of three basic elements: pigment or dye, carrier and additive. It is an aggregate made by uniformly loading super-normal pigments in the resin. It can be called a pigment concentrate, so its coloring power is higher than that of the pigment itself. When processing, a small amount of color masterbatch and uncolored resin is mixed to achieve the colored resin or product with the designed pigment concentration. [0003] The existing authorized announcement number is the Chinese invention patent of CN1058853...
