Manufacturing method of all-in-one EEB composite film

Abstract

The invention discloses a manufacturing method of all-in-one EEB composite film. The manufacturing method comprises following steps: A1, raw materials are prepared, wherein 100 parts of EVA(VA21%), 1.1 parts of zinc oxide powder, 0.54 part of stearic acid, and 0.7 part of a peroxide bridging agent are weighed; A2, EVA, zinc oxide powder, and stearic acid are subjected to rolling mulling using an open mill roller at a temperature ranging from 40 to 50 DEG C, then the peroxide bridging agent is added for uniform mixing, the thickness is controlled to be 3 to 4mm, an obtained mixture is subjectedto be mulling until uniform mixing is realized using the open mill roller; A3, the surface temperature of the open mill roller is controlled to be 10 to 15 DEG C, and obtained sheets are taken out from the open mill, wherein in sheet collecting process, horizontal sheet pulling out is adopted, the thickness is controlled to be about 0.4mm, and the deviation is lower than 0.1mm; and A4, the obtained sheet film is the all-in-one EEB rubber composite film, and is stored. The beneficial effects are that: in the manufacturing process of the all-in-one EEB composite film, glue is adopted for applying, the quality is stable, process is simple, cost is low, and environment protection requirements are satisfied.

Description

technical field [0001] The invention relates to the field of auxiliary materials for shoemaking, in particular to a method for manufacturing an integrally formed EEB binding film. Background technique [0002] In the prior art, when using EVA as the sole of the material, when EVA shoe materials with different characteristics are needed to combine the soles, the joints of the two different materials or colors are first cleaned and roughly machined. The joint is coated with glue, and then heat-pressed and shaped in the forming mold. The production process is complicated, and if the glue is not applied in place, the joint part will be detached, and the glue generally contains volatile harmful substances, which is easy to violate the environmental protection policy, and the process is long and the production cost is high. [0003] Aiming at the problems in the related technologies, no effective solution has been proposed yet. Contents of the invention [0004] The object of ...
