Embodiment 1

[0024] A surface spraying process for a leather case and bag, comprising the steps of:

[0025] 1) After the leather luggage is molded out of the ABS:PC mixed plastic substrate with a weight ratio of 3:7, a layer of colorless PU primer with a paint film thickness of 25 μm is sprayed on the surface of the plastic substrate;

[0026] 2) Put the bags sprayed with PU primer into the baking line and bake at 70°C for 30 minutes to make the primer on the surface of the substrate show irregular cracks;

[0027] 3) After spraying a layer of red paint with a paint film thickness of 30 μm on the primer layer of the luggage, put the luggage into the baking line and bake at 70°C for 30 minutes;

[0028] 4) On the color paint layer in step 3), spray a layer of transparent rubber paint with a paint film thickness of 45 μm, and put the bag into the baking line again and bake it at 70°C for 60 minutes.

[0029] After the above-mentioned spraying process on the leather luggage, on the surface ...

Embodiment 2

[0031] A surface spraying process for a leather case and bag, comprising the steps of:

[0032] 1) After the leather bags are molded out of the plastic substrate PVC, a layer of colorless PU primer with a paint film thickness of 30 μm is sprayed on the surface of the plastic substrate;

[0033] 2) Put the primer-coated bags into the baking line and bake at 65°C for 35 minutes to make the primer on the surface of the substrate show irregular cracks;

[0034] 3) After spraying a layer of yellow paint with a film thickness of 25 μm on the primer layer of the luggage, put the luggage into the baking line and bake at 75°C for 25 minutes;

[0035] 4) On the color paint layer in step 3), spray a layer of transparent rubber paint with a paint film thickness of 45 μm, and put the bag into the baking line again and bake it at 70°C for 55 minutes.

[0036] After the above-mentioned spraying process, on the surface of the ABS-PC mixed plastic base material of the leather luggage, there a...

Abstract

The invention discloses a surface spraying process of a leather bag. The surface spraying process comprises the following steps of (1) after a plastic base material of a bag is subjected to plate ejection molding, spraying a layer of priming paint on the surface of the base material, and baking and shaping the bag for 25 to 35 minutes at the temperature of 65 to 75 DEG C to enable the priming paint to be of an irregular cracking shape; (2) spraying a layer of color paint on the layer of priming paint of the bag, and baking and shaping the bag for 25 to 35 minutes at the temperature of 65 to 75 DEG C; (3) spraying a layer of rubber paint on the layer of color paint in the step (2), and baking and shaping the bag for 50 to 60 minutes at the temperature of 65 to 75 DEG C. By treating the leather bag through the surface spraying process, the surface of the leather bag is the rubber paint; the handfeel of the leather bag is fine and smooth, and the leather bag is colorful and textured; the surface hardness of the bag can reach 2HB, and the scratch resistance and abrasion resistance of the surface of the bag are improved.

Description

technical field [0001] The invention relates to a surface spraying process, in particular to a surface spraying process of leather bags. Background technique [0002] Existing bags can be divided into two categories: soft cases and hard cases in terms of materials. Soft cases are generally made of soft materials such as cloth or leather; hard cases are generally made of plastic materials, which are pasted with PC film and then molded out of the board. However, the surface hardness of the traditional hard case is very low due to the PC film, which is very easy to scratch, and the color change of the surface coating of the bag is small; while the surface of the traditional soft case has poor scratch resistance and friction resistance . Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a surface spraying process for improving the scratch resistance and friction resistance of leather bags. [...
