The invention provides a car matte part spraying method. The method comprises the following steps of pretreatment; strong cooling treatment, wherein a dried workpiece is placed in a strong cooling chamber, and the workpiece is cooled to the temperature of 23+ / -2 DEG C; flame treatment, wherein the cooled workpiece is subjected to flame treatment; priming paint spraying; colored paint spraying, wherein colored paint is sprayed to the workpiece with priming paint sprayed into a film in a spraying house by the adoption of a static electricity gun and an air gun, and three-coating matte black andmatte silver are adopted in the colored paint; varnish spraying, wherein varnish is sprayed to the workpiece with the colored paint sprayed into the film in the spraying house by the adoption of the static electricity gun, and matte varnish and high-light varnish with the ratio being 100:20 are adopted in the varnish; high-temperature paint baking; and strong cooling treatment. The ratio of the matte varnish to the highlight varnish is adopted to be 100:20, the use amount of the paint is reduced, the matte silver for adjusting glossiness is 25-35%, the matte black is 16-20%, the curing ratio reaches 3:1, and the surface hardness of the workpiece is adjusted.
Description
technical field [0001] The invention relates to the field of automobile paint spraying, in particular to a method for spraying automobile matte parts. Background technique [0002] Car painting refers to the effect of putting a layer of paint on the surface of the car to protect the car. Automotive spray paint includes: ordinary paint; metallic paint; pearlescent paint; varnish; matte paint. Varnish is a pigment-free transparent or light yellow paint with good gloss, fast film formation and wide application. The main ingredients are resin and solvent or resin, oil and solvent. After being applied to the surface of the object, a coating film with protection, decoration and special properties is formed, and a smooth film is formed after drying, showing the original pattern of the object surface. [0003] The traditional matte paint spraying is mainly two-component matte silver and matte black paint, which is sprayed by 1K equipment. There is only a single gear pump, which c...
