Embodiment 1

[0027] Embodiment 1, the water-based paint coating method that the Russian birch door panel in the present embodiment is white and solid closes, comprises the steps:

[0028] a. Material repair, using putty, and sanding with 320# sandpaper, for pits and bruises on the original material, repair with 502 glue, until there is no horizontal sand mark and the surface is smooth and smooth, then dry at 30°C for 4 hours ;

[0029] b. One time spraying, spraying water-based adhesion primer, spraying amount 95g / m 2 , and then dry at 30°C for 2 to 3 hours, the effect is to seal the oil and water in the wood, so that the UV transparent primer on the subsequent surface and the wood will have stronger adhesion;

[0030] c. Secondary spraying, use reciprocating spraying machine to spray UV transparent primer, mercury lamp 120~180cmj / m 2 , the spraying amount is 301.5g / m 2 , under constant temperature adjustment, dry for 5-8 minutes, and the temperature is controlled at 25-35 °C;

Embodiment 2

[0043] Embodiment 2, the water-based paint coating method of the Russian birch door panel in this embodiment is white and solid closed, without color registration and clear color treatment, but changed to gold painting and pure gold treatment, as follows: gold painting will not need to be painted by pasting masking paper Cover the position where the gold is painted, and then use a spray gun to spray the debugged gold on the product, remove the gold, remove the masking paper after the gold is painted, and clean the surface stains. For other structures, refer to Example 1.

Abstract

The invention discloses a water paint coating method for white closing of Russian birch door sheets. The method is characterized by comprising the steps of: material repair; spraying of water adhesive primer; spraying of UV spraying primer and spraying of UV transparent primer; multiple times of filling and polishing; and multiple times of water paint spraying. Because of no oil paint, but use of water paint, the product is safe and environment-friendly, the VOC content is reduced by 20 times compared with the oil paint, the product has no smell, and is high in surface hardness, difficult to scratch and higher in ultraviolet intensity resistance; and the coated door sheets are higher in surface gloss.

Description

technical field [0001] The invention relates to a coating method of a door panel, in particular to a coating method of a water-washed paint for a door panel. Background technique [0002] The wood of existing birch is light brown to reddish brown, with a shiny surface and smooth mechanism. Yellowish white slightly brown, with obvious annual rings, pure and fine wood body, slightly heavy and hard, fine structure, high mechanical strength, high elasticity, high hygroscopicity, easy to crack and warp when dry. It is not very durable in an environment prone to decay, and is more used in the form of plywood. Birch is usually used in special plywood, flooring, furniture, pulp, interior decoration materials, vehicle and ship equipment, plywood, etc. The furniture made is smooth and wear-resistant, with clear patterns. Today it is used for structures, marquetry and internal framing. Birch native to Russia is commonly known as (Russian birch). [0003] Using birch to make furnit...
