Abstract

The invention provides a high dyeability EVA color master batch special for shoes. The high dyeability EVA color master batch comprises, by weight, 30-70 parts of an EVA carrier resin, 5-20 parts of apigment, 5-10 parts of sucrose fatty acid ester, 3-7 parts of EVA wax, 3-7 parts of polyethylene wax, 4-8 parts of octadecanamide, 2-4 parts of white oil, 3-7 parts of oleamide, 3-7 parts of a coupling agent, 7-12 parts of a maleic anhydride graft compatilizer, 5-9 parts of an antioxidant, 2-6 parts of a light stabilizer and 10-40 parts of a filler. The high dyeability EVA color master batch special for shoes is prepared from the above raw materials through processes, has the advantages of no flow pattern, no color point, small color difference, good light aging resistance, strong resistanceto thermo-oxidative aging and good dispersibility and solves the existing EVA master batch problems of uneven color and large color difference in coloring.

Description

technical field [0001] The invention belongs to the field of plastic coloring, and in particular relates to a special EVA color masterbatch for shoe materials with strong coloring property and a preparation method thereof. Background technique [0002] EVA color masterbatch is a color masterbatch made of EVA (ethylene-vinyl acetate copolymer) as a carrier, and is widely used in shoe materials such as travel shoes, hiking shoes, slippers, sandals, etc. At present, the EVA masterbatch products provided in the domestic market are prone to problems such as flow marks, color spots, color difference, and poor dispersion when they are colored, which affects the appearance of shoe materials. Therefore, how to solve the problems such as flow lines, color points, color difference, and poor dispersion that are easy to occur when EVA masterbatch is colored is an urgent problem to be solved when EVA is colored. To this end, we start from the formula of the product, develop a new EVA col...
