a matte paint

Abstract

The invention discloses a flat coating, which consists of the following components in parts by weight: 30 to 50 parts of toluene diisocyanate, 10 to 15 parts of medium castor oil alkyd resin, 20 to 25 parts of propylene glycol methyl ether acetate, 5 to 15 parts of carboxyl saturated polyester resin, 1 to 5 parts of carbon black, 11 to 18 parts of nitrocellulose, 13 to 25 parts of melamine resin, 15 to 30 parts of short soybean oil alkyd resin, and 5 to 25 parts of vinyl chloride-vinyl acetate resin. The gloss stability of the flat coating is improved, the gloss stability has high baking resistance and surface smoothness, and the performance of the flat coating is improved.

Description

technical field

[0001] The present invention relates to a matte paint. Background technique

[0002] Matt paint is a commonly used paint, which can be sprayed on the shell of household appliances, equipment, furniture, etc., to increase the decorative performance and enhance their water resistance, light resistance, friction resistance and pollution resistance, so that the grade of the product is greatly improved. , to achieve the desired gloss, bright colors, beautiful and durable.

[0003] The problem of the matt coatings currently on the market is that the gloss of the matt coatings changes greatly in hot and cold ovens and ovens with different heating rates. It is an ideal gloss effect, but the gloss will rise to about 25 degrees when the cold oven starts baking, and even reach about 40 degrees when the user uses the paint, that is, the baking resistance of the matt paint is poor , The gloss stability is not good enough, which affects the quality of matt paint.
