Problems solved by technology

[0003] However, there are still the following problems: Putty and dust removal require workers to manually repeatedly apply putty or atomic putty on the surface of the equipment, which makes the construction progress of the steps of putty and dust removal slow, resulting in a longer cycle of the entire spraying operation, which makes The existing equipment surface spraying method is only suitable for small-scale spraying treatment, but cannot meet the needs of large-scale production of current equipment

Embodiment Construction

[0012] The present invention will be further described below in conjunction with specific embodiments.

[0013] A method for quick-drying spraying of mechanical surface paint, characterized in that it comprises the following steps:

[0014] A. Dry the surface for 20-30 minutes and then treat the surface of the active group with flame treatment or corona discharge to enhance the surface adsorption capacity until the thickness of the paint that can be adsorbed reaches the preset range;

[0015] B. To spray the primer, the distance between the spray gun and the sprayed surface is 10-30cm when spraying, keep the spray gun running at right angles to the surface of the object to be coated, the primer is white corundum sand grains, make the roughness reach 8-15μm, and dry 30 minutes; the parts by weight of the primer are: 50-80 parts of glass ceramic material, 5-10 parts of dichromium trioxide, 1-2 parts of iron red, 0.5-2 parts of manganese dioxide, 10-2 parts of mica powder 20 par...

Abstract

The invention discloses a quick-drying spraying method for mechanical surface paint, which comprises the following steps: A. surface treatment; B. primer treatment; C. intermediate paint treatment. Adopting the invention can effectively improve the mechanical surface gloss.

Description

technical field [0001] The invention relates to the technical field of mechanical surface processing, in particular to a method for quick-drying spraying of mechanical surface paint. Background technique [0002] The existing equipment surface spraying method includes surface treatment such as grinding, static electricity removal and dust removal on the equipment surface, and steps such as spraying primer, scraping putty, scraping dust and spraying color paint on the equipment. Among them, scraping putty and scraping dust is to remove the uneven part of the equipment surface by filling or overall treatment after the primer is sprayed on the surface of the equipment, so that the surface of the equipment is smooth and smooth, so that the paint can be effectively attached to the surface of the equipment, ensuring The appearance quality of the equipment surface. [0003] However, there are still the following problems: Putty and dust removal require workers to manually repeated...
