Problems solved by technology

The rubber material is characterized by flexibility, wear resistance, soft surface light, and good hand feeling; but in terms of craftsmanship, rubber coloring has always been very limited. The existing method is to directly add rubber coloring materials to the For pouring glue, get the corresponding color after pouring and drying
In this way, only a few monotonous basic colors are obtained, which cannot meet the strong demand of the market at all.
Therefore, the disadvantage of rubber materials is that there are few color varieties, especially the multiple colors that can not be flexibly and accurately selected on the surface of model parts according to the requirements of model design and the needs of users.
In the prior art, the rubber material is colored by simply spraying paints of various colors on the rubber surface. Since the rubber itself is an elastic material, during production and use, the rubber parts must often be stretched, compressed, bent, etc. by various external forces. Deformation, when the paint is directly sprayed on the rubber surface, its adhesion is difficult to meet the requirements
Because paint and rubber are not compatible with each other, and the elastic coefficient of general paint is smaller than that of rubber, when the rubber part is elastically deformed by external force, the paint attached to the rubber surface will also be deformed. When the elastic deformation of the paint exceeds its own elastic limit, it must be It will fall off, which makes it difficult to attach the paint coating on the rubber surface, and often cracks or even falls off, which directly affects the beauty and strength of the model surface

Abstract

A process for coloring directly on the surface of a rubber workpiece includes such steps as putting the rubber workpiece in a clean space, spraying a layer of rubber paint or the mixture of rubber paint and priming paint, baking, directly spraying a layer of paint needed by product, baking, spraying a layer of PU or rubber paint, and drying.

Description

technical field [0001] The invention relates to the field of industrial model manufacturing, in particular to a process method for directly coloring the surface of rubber materials. technical background [0002] With the advancement of science and technology and the development of industrial model manufacturing, there are more and more models with rubber layers on the surface of these materials, directly using rubber materials to make models or using other materials to make models. The rubber material is characterized by flexibility, wear resistance, soft surface light, and good hand feeling; but in terms of craftsmanship, rubber coloring has always been very limited. The existing method is to directly add rubber coloring materials to the For pouring glue, get the corresponding color after pouring and drying. In this way, only a few monotonous basic colors are obtained, which cannot meet the strong demand of the market at all. Therefore, the disadvantage of the rubber mate...
