Embodiment 1

[0022] A modified masterbatch, which is composed of the following raw materials in weight ratio: 40 parts of carrier, 5 parts of functional additive, 7 parts of pigment, 5 parts of dispersant; 15 parts of turpentine, 12 parts of nucleating agent, 2 parts of dispersant, 2 parts of magnesium stearate.

[0023] Further, the functional additive is an anti-ultraviolet additive, and the anti-ultraviolet additive is 2-hydroxy-4-n-octyloxybenzophenone.

[0024] Further, the functional additive is an anti-wear agent, and the anti-wear agent is A-186 anti-wear agent.

[0025] Further, the functional additive is an inorganic flame retardant, and the inorganic flame retardant is antimony trioxide.

[0026] Further, the carrier is a mixture of polyethylene terephthalate and polymer resin, the ratio of which is 2:5.

[0027] Further, the pigment is oil-soluble yellow 93.

[0028] Further, the dispersant is polyethylene wax.

[0029] Further, the nucleating agent is a rosin nucleating ag...

Embodiment 2

[0037] A modified color masterbatch, which is composed of the following raw materials in weight ratio: 80 parts of carrier, 20 parts of functional additive, 21 parts of pigment, 10 parts of dispersant; 25 parts of turpentine, 20 parts of nucleating agent, 5 parts of dispersant, Magnesium stearate 5 parts. Turpentine can make the pigment compatible with the carrier very well. Magnesium stearate makes the finely ground pigment particles not cause flocculation, but maintains a certain fineness.

Abstract

The invention discloses a modified color masterbatch and a preparation method thereof. The modified color masterbatch is composed of the following raw materials by weight: 40-80 parts of a carrier, 5-20 parts of functional additives, 7-21 parts of a pigment, 5-10 parts of a dispersant, 15-25 parts of turpentine, 12-20 parts of a nucleating agent, 2-5 parts of a dispersant and 2-5 parts of magnesium stearate. Through reasonable formula and proportion, the pigment and the carrier have good compatibility, pigment particles do not cause flocculation phenomenon, and protection of certain fineness facilitates production and processing. Also due to the setting of multiple functional additives, the finally modified color masterbatch has wear resistance, ultraviolet resistance, flame retardance andother characteristics. The production process adopted by the invention limits the pigment fineness, and sets special technological conditions. The lipophilic characteristic of pigment is utilized, the pigment enters turpentine from water flushing by kneading, and at the same time, the oily carrier coats the surface of the pigment, so that the pigment can be dispersed stably. Through the steps ofplasticization and then granulation, the tinting strength of the modified color masterbatch product is effectively improved.

Description

technical field [0001] The invention relates to the technical field of plastic technology, in particular to a modified color masterbatch and a preparation method thereof. Background technique [0002] Color masterbatch is a new plastic and fiber coloring product developed in the 1960s. It is a polymer compound prepared by uniformly loading pigments in resins. The masterbatch is mainly composed of three parts: colorant, carrier and dispersant. Masterbatch is a new type of polymer material colorant. It is a plastic colorant that is well dispersed with a high proportion of pigments or additives and thermoplastic resins. The selected resin has a good wetting and dispersing effect on the colorant. And it has good compatibility with the material to be colored. The existing masterbatch products can already meet the general needs, but there are still problems such as poor UV resistance and general tinting strength. Contents of the invention [0003] The technical problem to be ...
