Abstract

The disclosure discloses a method for forming a rubber layer on a surface of a resin material. In the method, painting is first performed on the surface of the resin material to form a painting layer, using a paint to which a pigment has been added; then, rubber coating is performed to form a rubber layer on the painting layer. The method of the disclosure may be used in surface treatment of a fastener product. The disclosure further discloses a slide fastener, a buckle and a snap button using the method of the disclosure. The method of the disclosure may solve a conventional problem that a rubber coating is likely to fall off a resin surface, and the rubber on the surface of the resultant fastener product is less likely to fall off.

First claim

What is claimed is:

1. A resin material structure of a slide fastener element, comprising:
the slide fastener element having a resin material body, wherein a painting layer and a rubber layer are sequentially formed from inside to outside on a surface of the resin material body of the slide fastener element, a bottom surface of the rubber layer is entirely covered by the painting layer, and a paint for forming the painting layer contains a pigment.

2. The resin material structure of the slide fastener element according to claim 1 , wherein the paint is an oil-based paint or a water-based paint, and the pigment is a color pigment.

3. The resin material structure of the slide fastener element according to claim 1 , wherein the paint for forming the painting layer is selected from an epoxy resin paint, an acrylic urethane paint, an acrylic melamine resin paint, a polyurethane paint, an alkyd resin paint, an acrylic paint, a chlorinated olefin paint, a polyurea elastomer, a silicone resin paint, a polysiloxane paint, a fluorine-containing polymer paint, an unsaturated polyester paint, a vinylester paint, or a polyaniline paint.

4. The resin material structure of the slide fastener element according to claim 1 , wherein in the paint for forming the painting layer, the pigment has a weight percentage of 10% to 30%.

5. The resin material structure of the slide fastener element according to claim 1 , wherein the painting layer has surface roughness of 2 μm to 7 μm.

6. The resin material structure of the slide fastener element according to claim 1 , wherein the pigment is one or more of chrome yellow, antimony yellow, iron oxide yellow, cadmium yellow, hansa yellow, benzidine yellow, chromium oxide green, chrome green, iron blue, ultramarine blue, iron red, cadmium red, molybdate red, iron black, aluminum powder, copper powder, zinc oxide, lithopone, titanium white, antimony white, white lead, graphite, aniline black, and carbon black.

7. The resin material structure of the slide fastener element according to claim 1 , wherein the painting layer has a thickness of 30 μm to 50 μm.

8. The resin material structure of the slide fastener element according to claim 1 , wherein the painting layer fully or partially covers the surface of the resin material body, and the rubber layer fully covers the painting layer.

9. The resin material structure of the slide fastener element according to claim 1 , wherein the painting layer and the rubber layer are formed using a method that comprises:
first, performing painting on the surface of the resin material body to form the painting layer, using a paint to which a pigment has been added; and
then, performing rubber coating to form the rubber layer on the painting layer.

10. The resin material structure of the slide fastener element according to claim 1 , wherein the painting layer fully or partially covers the surface of the resin material body, and the rubber layer partially covers the painting layer.
