Abstract

The invention belongs to the technical field of color master batch, and especially relates to a color master batch, and a preparation method thereof. The color master batch comprises, by weight, 24 to30 parts by weight of LLDPE; 24 to 30 parts by weight of LDPE; 5 to 7 parts by weight of calcium carbonate; 10 to 15 parts by weight of starch; 25 to 35 parts by weight of titanium dioxide; 1 to 6 parts by weight of a titanate coupling agent; 1 to 6 parts by weight of lauryl sodium sulfate; 7 to 11 parts by weight of a primary dispersant; and 1 to 3 parts by weight of a secondary dispersant. Thepreparation method comprises following steps: 1, titanium dioxide powder pre-treatment; 2, calcium carbonate pre-treatment; 3, mixing; and 4, granulation. According to the preparation method, LLDPE and LDPE are taken as carriers, and the processing rheological property of the color master batch is better than that of master bath taking LDPE as a carrier.

Description

technical field [0001] The invention belongs to the technical field of color master batches, in particular to a color master batch and a preparation method thereof. Background technique [0002] Masterbatches are pigment preparations, which are aggregates made by uniformly attaching super-normal colorants to resins by a special method, also called pigment concentrates, and are high-efficiency coloring materials dedicated to new polymer materials. preparation. [0003] Color masterbatch is generally composed of three parts: carrier resin, pigment and dispersant. Commonly used inorganic pigments are: cadmium red, cadmium yellow, titanium dioxide, carbon black, iron oxide red, iron oxide yellow, etc. For the color masterbatch with titanium dioxide as pigment, due to the large particle size of titanium dioxide, the dispersion effect of titanium dioxide particles in the system is poor, and the processing rheological properties are poor. Contents of the invention [0004] The...
