Problems solved by technology

However, the existing color masterbatches have no antibacterial and bactericidal effects, and cannot be used in industries that require high bacterial content. At the same time, plastic filaments are prone to confusion before granulation, which is not conducive to actual granulation. To set the screening structure, it is necessary to increase the screening mechanism for screening processing, which is not conducive to the rapid production of enterprises

Abstract

The invention discloses a preparation method of an antibacterial color master batch. The antibacterial color master batch is prepared from the following components in parts by weight: 15 to 25 parts of silver-loaded silica gel, 25 to 32 parts of a coloring agent, 1.2 to 2.5 parts of a benzotriazole derivative, 1.2 to 1.8 parts of a titanate coupling agent, 1.6 to 3.5 parts of ethylene bis stearamide, 1.5 to 2.4 parts of a 2-phenyl compound and 78.5 to 88.6 parts of linear low-density polyethylene, The silver-loaded silica gel, the coloring agent, the benzotriazole derivative, the titanate coupling agent, the ethylene bis stearamide, the 2-phenyl compound and the linear low-density polyethylene are used as raw materials for preparing the antibacterial color master batch, and the prepared antibacterial color master batch has excellent antibacterial and fungal effects; the benzotriazole derivative, the titanate coupling agent and the ethylene bis stearamide are matched, so that the adverse effect of the addition of the antibacterial agent on the dispersion effect of the pigment in the master batch is reduced, and the coloring power of the pigment is improved.

Description

technical field [0001] The invention relates to the technical field of color masterbatch and its preparation process, in particular to a preparation method of antibacterial color masterbatch. 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] After the masterbatch is kneaded by a high-speed kneader, it is crushed, extruded...
