Embodiment 1

[0026] Embodiment 1: the varnish construction technology of solid wood wooden box surface

[0027] (1) Clean the surface of the sample: clean the dust and dirt on the surface of the wooden box;

[0028] (2) Sanding: Use sandpaper to polish the burrs and protrusions of the wooden box to obtain a smooth and flat surface;

[0029] (3) Apply the polyurethane transparent primer by spraying. After the coating is completed, quickly put the object into the vacuum box, start the vacuum pump to vacuum for 60 seconds, then take it out and dry it. After it is completely dry, sand it with sandpaper to make it smooth;

[0030] (4) Repeat step (3) twice;

[0031] (5) Apply polyurethane transparent topcoat by spraying. After the coating is completed, quickly put the object into the vacuum box, start the vacuum pump to vacuum for 120 seconds, and then take it out to dry in the natural environment.

Embodiment 2

[0032] Embodiment 2: the coating construction technology of aluminum alloy handicraft.

[0033] (1) Clean the dirt on the surface: first use an organic solvent to remove the dirt such as oil stains attached to the surface of the aluminum alloy;

[0034] (2) Surface activation treatment: Use phosphating solution or phosphating primer to treat the surface of aluminum alloy, and after reacting with aluminum alloy, form an aluminum phosphide film that paint is easy to adhere to, clean and dry;

[0035] (3) Dust, oil, water vapor and other dirt are not allowed on the treated surface. After the surface treatment meets the coating requirements, immediately use the spraying method to coat the aluminum alloy transparent primer. After the coating is completed, quickly put the object into the vacuum Start the vacuum pump to evacuate the box for 60 seconds, then take it out and dry it;

[0036] (4) After drying, use the method of spraying to apply transparent color paint. After the coati...

Abstract

The invention relates to a device for preventing blanching of a coating material. The device comprises a box body provided with an opening, wherein the box body is connected with a vacuumizing device through an exhaust tube, an exhaust valve is further arranged in the box body, and a box door used for opening and closing the box body is arranged on the opening of the box body. The invention further discloses a production technology for coating material processing by means of the device. The production technology comprises the steps of placing a well coated object into the vacuum box body quickly, conducting vacuum treatment for a period of time, opening the exhaust valve, and taking out the object for drying and solidification. According to the device for preventing blanching of the coating material and the production technology using the same, the quick vacuum treatment method is introduced to coating material processing, through short-time vacuum tightness extraction of the object, volatilization of low-boiling-point micromolecule organic solvents is accelerated, and meanwhile, the occurrence of blanching of a coating especially a transparent paint film caused by factors such as high moisture of a construction environment is reduced.

Description

technical field [0001] The invention relates to a paint processing device and a method thereof, in particular to a device for preventing paint from fogging and a production process thereof. Background technique [0002] Coating (paint) is a kind of coating on the surface of objects by different construction techniques to form a solid film with strong adhesion, certain strength and continuity. Because of its significant protection, decoration, color marking and other special effects on metal, wood, plastic and other materials, it has been widely used in furniture, home decoration, electronics, electrical appliances, handicrafts, automobiles and other industries. In the process of coating construction, due to factors such as environmental humidity, temperature, coating formula, coating process and other factors, the coating, especially the transparent paint film, is prone to obvious whitening phenomenon, which affects the appearance and decoration effect of the coated object a...
