AI Technical Summary

Problems solved by technology

During the construction of UV curable coatings, the paint film will appear blistering, paint film cracking, paint film peeling off (poor adhesion) and other common phenomena, even if the type or composition of the paint is changed, the phenomenon of paint film blistering and cracking cannot be overcome , causing the appearance of the painted material to fail to achieve the required decorative effect, which seriously brings great economic losses and reputation damage. There is no paint or method that can overcome this phenomenon.

Embodiment 1

[0035] Embodiment 1: The spraying construction technology that prevents the paint film of medium density board to be coated with from turning white

[0036] The object to be coated is a decorative material composed of medium density boards, and the object to be coated is carried out to prevent the construction method of the UV-cured paint film from foaming, comprising the following steps:

[0037] 1) Sanding the object to be coated: use sandpaper to sand the burr of the object, and sand it smooth;

[0038] 2) Coloring of the object to be coated: use ultraviolet light to color the high-adhesion primer (top primer), evenly roller coat, and UV curing machine to cure and dry completely;

[0039] 3) Sanding: use sandpaper to sand flat and smooth;

[0040] 4) Adjust the construction viscosity of the UV-curable spray transparent primer (surfacer) to 16 seconds with a special thinner for UV-curable activity, and spray a "ten" evenly, with a temperature of 40°C and a length of 10 mete...

Abstract

The invention provides a method for preventing bubbles of a UV-curing paint coating. The method comprises the following step: performing infrared-light levelling treatment for 3.5 to 5 minutes at a levelling temperature of 40 to 50 DEG C after priming paint or finish paint coating. The construction method provided by the invention can effectively prevent the adverse effect of bubbles of the UV-curing paint coating; has the advantages of high curing speed, low energy consumption, good performance of the curing product and adaptability for high-speed automatic production; and can meet the needs for production enterprises of wood doors, furniture, staircases, kitchen cabinets and other wood or wood composite products.

Description

technical field [0001] The invention relates to a construction method of an ultraviolet light curing paint, in particular to a method for preventing foaming of the ultraviolet light curing paint film. Background technique [0002] UV-curable coatings (ie, UV-curable coatings) have the advantages of no volatile organic compounds (VOC), less environmental pollution, fast curing speed, energy saving, good performance of cured products, and suitable for high-speed automatic production. However, traditional coatings are volatile and slow to cure, which is not conducive to environmental protection. Therefore, UV-curable coatings are a major substitute for traditional coatings. The paints used by manufacturers of furniture, cabinets, and wooden handicrafts are usually NC, PU, ​​and PE. With the development of paint coating technology and the enhancement of consumers' awareness of environmental protection, a new type of furniture UV curing coating has emerged. UV curable coatings...
