Description

Decorative coating and spraying method thereof

Technical field

The invention relates to the field of construction, home improvement, kitchen appliance, furniture, automobile, and various industrial product processing, and particularly relates to a decorative coating and a spraying method thereof.

Background technique

Decorative panels, especially metal decorative panels, have both unique gloss and strength, as well as strong corrosion resistance. Therefore, since the advent of the decorative panels in the 1970s, they have been widely used in the fields of building materials, chemicals, automobiles, electronics, and arts and crafts.

At present, in order to color the metal decorative board, especially the use of traditional paint, it requires a certain pretreatment, including the following steps: degreasing, chemical cleaning, whitewashing, water washing, air drying and baking, among which, the whitening process is mostly adopted. High concentration (about 40%-60%) of nitric acid, high risk factor, great harm to human body and environment, and the substrate after whitewashing is mostly grayish white and often accompanied by poor extinction; often it is blunt after washing white The layer is destroyed and the corrosion resistance is lowered, and it is easy to leave marks on the surface of the substrate by hand touch.

Chinese invention patent CN104742435A discloses a "slip-resistant acid-proof and anti-corrosion stainless steel plate", which comprises a stainless steel plate body. The stainless steel plate body is provided with a plurality of mutually staggered anti-slip stripes.
