Abstract

The invention belongs to the technical field of preparation of special color master batches, and particularly relates to a preparation method of a special color master batch for an EVA shoe material, which comprises the following steps: S1, mixing EVA carrier resin, pigment and filler, and adding into an internal mixer for internal mixing; s2, adding the internally mixed material blocks obtained in the step S1 into an open mill for thin-passing to obtain crushed material blocks; s3, mixing the crushed material blocks obtained in the step S2 with EVA wax, a coupling agent, a stabilizer, an antioxidant and a lubricant, and adding the mixture into an internal mixer for internal mixing; s4, adding the internally mixed material blocks obtained in the step S3 into a screw extruder for extrusion, granulating through a granulator, filtering the mixture through a screen to remove substandard products, and ventilating and cooling the mixture to obtain the special color master batch for the EVA shoe material. According to the special color master batch for the EVA shoe material, the EVA carrier resin is taken as a basic raw material, so that the colorability is good, and the special color master batch can be conveniently mixed with other raw materials for processing and forming.

Description

technical field [0001] The invention relates to the technical field of preparation of special color masterbatches, in particular to a preparation method of special color masterbatches for EVA shoe materials. Background technique [0002] EVA is produced by the copolymerization of ethylene and vinyl acetate. The Chinese name is: ethylene-vinyl acetate copolymer (also known as ethylene-vinyl acetate copolymer), referred to as EVA. Average molecular weight in EVA: 10000-30000. EVA is widely used in a wide range of applications, and the annual market consumption in my country is constantly increasing, especially in the shoe industry, where it is used in the soles and interior materials of mid-to-high-end travel shoes, hiking shoes, slippers, sandals. [0003] EVA masterbatch is mostly used to fill the color in the process of shoe material processing. In the preparation process of the existing EVA shoe material special color masterbatch, the use effect of the color masterbatch i...
