Embodiment Construction

[0025] The following examples are further explanations and illustrations of the present invention, and do not constitute any limitation to the present invention.

[0026] The method for spraying crack paint of the present invention comprises the steps:

[0027] a. Dilute the PP gray polypropylene primer with PP (polypropylene) solvent at a ratio of 1:0.85 (parts by weight) for 12 minutes, control the viscosity of the paint by controlling the time, and then spray it on the product made of modified polypropylene material surface.

[0028] b. Dry the sprayed polypropylene primer at a temperature of 68° C. for 20 minutes to volatilize the solvent. Dilute the 206 type acrylic black primer with X3 (xylene solvent) in a ratio of 1:1 (parts by weight) for 15 minutes. Seconds, dry at 70°C for 15 minutes and then spray on the dried polypropylene primer, then let it cool until the surface is dry.

[0029] This step is used to strengthen the intermediate coating interface, the joint bet...

The invention has low cost.

Description

technical field [0001] The invention relates to a method for spraying the surface of workpieces, in particular to a method for spraying crack paint on the surface of workpieces so as to present skin texture effects. Background technique [0002] Spraying paint on the surface of workpieces is a common surface treatment method. Among them, spraying paint on the surface of metal workpieces is mainly to prevent corrosion of workpieces and play a decorative role. On the other hand, non-metal products, such as plastic or leather products, are painted to produce a decorative effect, mainly to produce a leather effect. This surface treatment is more common in automotive interior parts. At present, there are generally two ways to produce the surface grain of automobile interior parts: one is to use leather decoration, the other is to imitate leather grain, and the latter is to process and produce by making molds. The main defect of the above two ways is that the production cost is r...
