Process for coloring rubber material surface

Abstract

The invention relates to a process method for coloring the surface of a rubber material, which comprises the following steps: cleaning the inside of the half-side silicone mold of the appearance surface of the product to be produced, and spraying the surface paint of the product on the mold of the appearance surface at normal temperature and pressure The inner surface, with a thickness of 5 to 40 microns, is naturally placed for 5 to 10 minutes, and the rubber is poured into the mold at a pressure of 85 to 130 kPa, so that the cast rubber product and its mold stay in the vacuum machine for 50 seconds to 90 Seconds later, take it out and bake in an oven at 60°C to 85°C for 2 to 4 hours, then place the product in a refrigerator at a temperature of 0°C to 10°C to cool down for 20 to 40 minutes, after curing, open the mold and take it out; The above process is used to color the rubber surface, which can accurately select the color according to the design requirements, and prevent the color attached to the surface of the rubber product from cracking, and has high impact resistance.

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
