Production technology for coarse double-grain rubber slab

Abstract

The invention discloses a production technology for a coarse double-grain rubber slab. The production technology comprises the following steps: 1) raw material pretreatment; 2) weighing preparation; 3) mixing; 4) calendering; 5) cooling; 6) grain cloth pretreatment; 7) vulcanization; 8) inspection; and 9) trimming, inspection and packaging. The production technology improves the pretreatment of arubber compound, and correspondingly refines latex reclaimed rubber and natural rubber, so the plasticity of the latex reclaimed rubber is improved, subsequent calendering, extrusion and molding are facilitated, and the obtained coarse double-grain rubber slab has a stable shape and a clear pattern.

Description

Technical field [0001] The invention relates to a production process involving a thick double-texture rubber sheet. Background technique [0002] Coarse double-texture rubber sheet is combined with cloth-pattern cloth to achieve the shape of cloth-pattern cloth on the top and bottom of the rubber sheet during the production process. The existing double-texture rubber sheet production process is due to There are problems in the selection and pretreatment of the glue solution, resulting in the production of rubber sheets that cannot meet higher requirements in terms of hardness and other properties. At the same time, the surface quality of the finished rubber sheets is poor, which affects the appearance; [0003] Secondly, because there is no more suitable cooling device and method before the calendering step in the production process, the rubber sheet is not cooled in time, resulting in poor cooling and solidification effect, and the cooling gap between the inside and outside of the...

AI Technical Summary

Problems solved by technology

[0002] Coarse double-grain rubber sheet is in the process of rubber sheet production through the combination of cloth-grain cloth to achieve the shape of cloth-grain cloth on the upper and lower sides of the rubber sheet. The existing coarse double-grain rubber sheet production process is due to There are problems in the selection and pretreatment of the glue solution, which leads to the production of rubber sheets that cannot meet higher requirements in terms of hardness and other properties. At the same time, the surface quality of the finished rubber sheets is poor, which affects the appearance;

[0003] Secondly, because there is no more suitable cooling device and method before the calendering step in the production process, the cooling of the rubber sheet is not timely, resulting in poor cooling and solidification effect, and the cooling gap between the inside and outside of the rubber sheet is large, which affects the subsequent steps. progress, which in turn affects the quality of the product
