Surface forming process for foam rubber product with patterns

Abstract

The invention discloses a surface forming process for a foam rubber product with patterns. The surface forming process comprises the following specific steps: mixing rubber; stacking up a layer of specially-processed high-temperature-resistance vinylon canvas in a vulcanizing mold; vulcanizing forming, ensuring that a foam rubber material is subjected to a series of complex chemical reactions during vulcanizing compression molding, and thereby, forming the foam rubber product, the surface of which is provided with the patterns; inspecting the finished product and putting the inspected finished product in storage. The selected high-temperature cloth with the patterns can be changed aperiodically, so that a surface pattern effect of the produced foam product is largely improved, lines are clear, the patterns are uniformly convex and concave, the air tightness is great, and the appearance of the product is beautiful. According to the surface forming process for the foam rubber product with the patterns, the surface of the mold is not subjected to a pattern drawing processing, so that the mold processing costs are largely reduced; furthermore, the cleaning times of the mold is reduced, the service life of the mold is prolonged, and meanwhile, the field production operation is convenient.

Description

technical field [0001] The invention relates to a surface treatment process of a rubber product, in particular to a surface forming process of a patterned rubber foam product. Background technique [0002] General rubber foam products have two types of surface pattern and surface without pattern from the appearance surface. The appearance of the product mainly depends on the stage of vulcanization and molding. Generally, the surface of the mold is selected for treatment, and after vulcanization and molding, patterns will appear. After long-term use, the mold will wear to a certain extent, and the patterns of the produced products will be deformed to varying degrees. At present, the general production method of foamed products with patterns on the surface is: choose to carry out pattern processing on the surface of the mold, and after molding and foaming, it is thought that there are beautiful and full pattern patterns. In fact, the molding and foaming process in which patt...

AI Technical Summary

Problems solved by technology

In fact, the molding and foaming process of drawing patterns on the surface of the mold, because it is a metal surface, the air is not good enough, and it is difficult to make foam products with beautiful and full patterns.

At this time, the pattern on the surface of the product will not be full, there will be insufficient material, incomplete patterns, and the appearance will not be good.
