Modified color masterbatch and preparation method thereof
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.
