Masticating process of calendered grass-green rubber strip glue for Jiefang shoes

Abstract

The invention discloses a plastifying process for calendering type grass green rubber foxing rubber for liberation shoes. The process comprises the following steps: weighing 4-5 parts of butadiene-styrene rubber, 25-35 parts of natural rubber, 0.2-0.4 part of an anti-aging agent KY-405L, 2-3 parts of composite resin DS-B and 0.2-0.5 part of a peptizer DS-T-1; cutting the natural rubber into 10-15kg / block rubber blocks, inputting 4-6 parts of cut natural rubber into an internal mixer, covering, then, inputting the composite resin DS-B and the peptizer DS-T-1, after mixing for 3 minutes, adding the anti-aging agent KY-405L, and mixing till the anti-aging agent KY-405L is uniformly dispersed; then, adding butadiene-styrene rubber and residual natural rubber (after addition, how long is the mixture mixed or are butadiene-styrene rubber and residual natural rubber are directly added into an open internal mixer.) and discharging to obtain mixed rubber; and inputting the mixed rubber into the open internal mixer, operating, deplaning and overturning for 6-8 times under the roll nip of 0.5-1mm, and rolling a rubber sleeve in regulated heavy weight class according to demand and sampling and detecting the Weishi plasticity of 0.50-0.55 to obtain the calendering type grass green rubber foxing rubber for liberation shoes.

Description

technical field [0001] The invention relates to the field of rubber material preparation, in particular to a plasticating process of calendered grass-green rubber wrapping glue for Jiefang shoes. Background technique [0002] At present, the plasticating process of calendered grass-green 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. Then put the crushed rubber into an 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 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 material and high work e...
