Thick double-grain-line rubber plate production process based on physical repair method

Abstract

The invention discloses a thick double-grain-line rubber plate production process based on a physical repair method. The thick double-grain-line rubber plate production process comprises the followingsteps of pretreating raw materials, weighing and preparing materials, (3) banburying, (4) calendering, (5) pretreating grain-line fabric, (6) vulcanizing, (7) inspection, and (8) cutting edges, inspecting and packaging. According to the production process, the pretreatment of a rubber material is improved, latex reclaimed rubber and natural rubber are correspondingly refined, the plasticity of the latex reclaimed rubber is improved, subsequent calendering, extrusion and mold pressing are facilitated, the shape is stable, and patterns are clear; and a repairing and arranging device is reasonable in design, high in automation degree, time-saving and labor-saving, and more thorough in bubble pricking and repairing, and the quality is further improved.

Description

technical field [0001] The invention relates to a production process of a rough double cloth rubber sheet based on a physical repair method. Background technique [0002] Coarse double-grain rubber sheet is made by combining cloth-grain cloth in the process of rubber sheet production 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 based on physical repair method In the process of processing, due to problems in the selection and pretreatment of the glue solution, the produced rubber sheet cannot meet higher requirements in terms of hardness and other properties. At the same time, the surface quality of the finished rubber sheet is poor, which affects the appearance; [0003] Secondly, during the processing of the coarse double cloth rubber sheet, one of the procedures is to perform foaming and repairing operations on the processed finished rubber sheet before the final...

Problems solved by technology

[0002] Coarse double-grain rubber sheet is made by combining cloth-grain cloth in the process of rubber sheet production 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 based on physical repair method In the process of processing, due to problems in the selection and pretreatment of the glue solution, the produced rubber sheet cannot meet higher requirements in terms of hardness and other properties. At the same time, the surface quality of the finished rubber sheet is poor, which affects the appearance;

[0003] Secondly, during the processing of the coarse double cloth rubber sheet, one of the procedures is to perform foaming and repairing operations on the processed finished rubber sheet before the final packaging inspection, because after the vulcanization operation, the inspection of the surface of the rubber sheet Before the quality, there will be some air bubbles generated by a series of operations such as vulcanization on the rubber sheet. At the same time, the surface of the rubber sheet is not smooth enough. It is necessary to carry out fine surface treatment operations on the finished rubber sheet to improve the final quality of the product. However, at present For the above problems, the manual operation method is mainly used. The disadvantages of this method are: firstly, the labor intensity is high, time-consuming and labor-intensive, and it is easy to have blind spots for soaking, or the air bubbles cannot be completely disposed of; secondly, it cannot At the same time, the flatness of the surface of the rubber sheet is further processed
