LED curing high-filling vacuum spraying primer and preparation method thereof

Abstract

The invention relates to an LED curing high-filling vacuum spraying primer and a preparation method thereof. The primer is prepared from 30 to 40% of amine modified polyester acrylic resin, 5 to 10% of polyurethane acrylic resin, 5 to 10% of a thermoplastic acrylic resin semi-finished product, 20 to 30% of DPGDA, 1 to 3% of an ITX photoinitiator, 2 to 5% of a TPO photoinitiator, 0.2 to 0.5% of an acrylic leveling agent, 0.3 to 0.5% of a non-silicon defoaming agent, 0.3 to 0.5% of a wetting dispersant, 3 to 5% of a fumed silica semi-finished product,6-10% of talcum powder and 2-5% of polymer resin particle powder; the obtained LED curing high-filling vacuum spraying primer is environmentally friendly and high in utilization rate, a flat paint film can be obtained on the surface of wood through one-time coating, the coating frequency can be reduced, and the use cost of the primer is greatly reduced; and the paint film also has good surface dryness, adherence, flexibility, hardness and polishing property.

Description

technical field [0001] The invention belongs to the technical field of wooden furniture lacquer, in particular to an LED curing high-filling vacuum spraying primer and a preparation method thereof. Background technique [0002] In the field of wooden furniture, supporting small workpieces, such as lines, door lines, etc., due to the small area of ​​these small workpieces and the low solid content of traditional solvent-based primers, when using traditional solvent-based primers, It will lead to a very low paint utilization rate, which will not only cause paint waste, prolong the drying time, increase the coating cost of these small workpieces, but also increase VOC emissions, causing serious environmental pollution. Based on this, LED curing vacuum spray coating is a spray coating and curing method based on the principle of vacuum negative pressure. Since the entire spray process is carried out in a vacuum box, it can make UV coatings with high solid content 100 % Uninterru...

AI Technical Summary

Problems solved by technology

[0003] However, the existing UV vacuum spraying primers suitable for LED curing vacuum spraying coatings also have the defect of poor filling performance, and generally require multiple coats to achieve the desired coating effect, which will not only increase the use cost of these primers , will also affect the production efficiency of these small workpieces
