Plastication process for calendering type black rubber edge strip gum for liberation shoes

Abstract

The invention discloses a plastication process for calendering type black rubber edge strip gum for liberation shoes. The plastication process comprises the steps: weighing 6 to 8 parts of styrene-butadiene rubber, 45 to 55 parts of natural rubber, 0.8 to 1.2 parts of an antioxidant CD, 0.2 to 0.4 part of an antioxidant KY-405L, and 4 to 6 parts of composite resin DS-B in terms of weight parts; cutting the natural rubber into rubber blocks of 15-20kg / block, putting the well-cut natural rubber, the styrene-butadiene rubber and the composite resin DS-B into a mixer, internally mixing for 3 minutes, then adding the antioxidant CD and the antioxidant KY-405L, mixing for 4 minutes, and discharging the materials to obtain the mixed rubber; and putting the mixed rubber into an open gum refining machine, starting the operation for turning and refining 6 to 8 times under the roller spacing of 5 to 6mm, rolling a specified weight level of rubber sleeves according to needs, sampling and detecting the rubber material to ensure that the Williams plasticity is 0.33 to 0.38, thereby obtaining the plasticated rubber of the calendering type black rubber edge strip gum for the liberation shoes.

Description

technical field [0001] The invention relates to the field of rubber material preparation, in particular to a mastication process of calendered black rubber wrapping glue for Jiefang shoes. Background technique [0002] At present, the plasticating process of calendered black rubber skirting rubber for Jiefang shoes adopts the open rubber mixing machine plasticating method. First, the rubber block is baked in an environment of 40-60°C to soften, and then the rubber block is broken, and then Put the broken rubber material into the open rubber mixer with a roller distance of 0.5-1mm and a roller temperature of 40-45°C and pull it through several times to make the plasticity of the rubber material meet the requirements. The problem with this plasticizing process is that strict temperature control is required, and a large amount of cooling water of the rubber mixing machine is required to lower the temperature of the rollers to ensure the stability of the plasticity of the rubber...

AI Technical Summary

Problems solved by technology

[0003] The object of the present invention is to provide a plasticating process for calendered black rubber skirting rubber for Jiefang shoes, which uses an internal mixer instead of an open rubber mixing machine for rubber plasticating, and solves the problem of plasticizing through reasonable feeding sequence design The plasticity fluctuation is large, the labor intensity is high, and the weakness of the original open-type rubber mixing machine plasticizing process is low in safety, so as to achieve less dust flying, less land occupation, anti-aging agent KY-405L, composite resin DS-B and other materials in the rubber compound The technical problems of uniform dispersion and stable quality of the rubber material have achieved the technical effect of stable performance of the rubber material molding process. Because the plasticity is at a reasonable level, the hardness of the mixed rubber meets the requirements of clear patterns and overcomes the shortcomings of the existing technology.
