Abstract

The invention provides polyester resin color master batch which is prepared from the following raw materials in percentage by weight: 45-55% of toner, 2-4% of a dispersing agent, 1-2% of a stabilizer, 2-3% of a wetting agent, 0.5-1.5% of a lubricating agent, 1-2% of an auxiliary agent and the balance of polyester resin, and the sum of the weight percentages of the raw materials is 100%. The invention also provides a preparation method of the polyester resin color master batch. The polyester resin color master batch provided by the invention has better dispersity, heat resistance, alkali resistance and weather resistance.

Description

technical field [0001] The invention relates to a polyester resin master sand and a preparation method thereof. Background technique [0002] The color masterbatch is an aggregate obtained by uniformly loading the pigment or toner in the resin. The color masterbatch is generally mainly composed of components such as pigment, dispersant and carrier resin. The use of color masterbatch can complete the coloring and product processing at one time, avoid the heating process of granulation and coloring, protect the quality of the product, simplify the production process of the product, and save energy consumption. In addition, the color masterbatch has the following advantages: 1. It is beneficial to Keep the chemical stability of the pigment and the stability of the color; 2. Make the pigment have better dispersibility in plastics or coatings; 3. Protect the health of operators; 4. Keep the environment clean and do not stain utensils; 5. Save time and raw materials.
