AI Technical Summary

Problems solved by technology

This method is not suitable for electrostatic powder spraying. On the one hand, the melamine production process is highly polluting and does not meet environmental protection; on the other hand, the hot-melt adhesive used is thermoplastic adhesive, which melts again in the infrared heating process, which is not suitable for powder coatings. Spray curing process
The environmentally friendly furniture produced by Litai Furniture (Qingyuan) Co., Ltd. uses melamine film as the edge sealing method. Although it can withstand temperature, it cannot handle special-shaped edges and completely solve the problem of long-term cracking of edges and corners.

preparation example Construction

[0036] The preparation method in the embodiment is as follows:

[0037] The preparation method of the highly active powder is as follows:

[0038] Proportion raw materials according to the active powder formula → machine mixing in the mixer → co-extrusion (the temperature of each zone of the screw is controlled at 80±3°C) → tabletting → crushing → grinding → sieving and classification → high activity Powder.

[0039] The preparation method of described highly active water-based powder slurry is as follows:

[0040] Water-based acrylic resin → add to the dispersion tank → add high-activity powder → emulsify → add film-forming aids, degassers, pigments and fillers, other additives → disperse → finished product.

Abstract

The invention belongs to the field of water-based paint and particularly relates to a high-activity water-based powder slurry for sealing the edges and the bottom of an artificial board. The high-activity water-based powder slurry is prepared by adding high-activity powder into water-based acrylic resin and then adding an additive. The high-activity water-based powder slurry has the characteristics of water base, environment protection and high solid content; since the active powder is added in the water-based coating, the high-activity water-based powder slurry not only has the characteristics of fast film forming, thermoplasticity and the like of water-based paint, but also has the characteristics of high-activity powder, thermosetting netted crosslinking, temperature resistance, excellent closure and the like.

Description

technical field [0001] The invention belongs to the field of water-based coatings, in particular to a highly active water-based powder slurry for edge and bottom sealing of artificial boards. Background technique [0002] The annual output of China's man-made panels (MDF) is about 30 million cubic meters. If calculated according to the thickness specification of 16mm panels, the annual output of MDF will reach 1.8 billion square meters. In recent years, due to the well-known advantages of powder coatings such as zero VOC content, more and more wood and furniture manufacturers want to use powder electrostatic spraying to impart good adhesion to the coated substrate and excellent scratch resistance and stain resistance of the coating. The advantages of safety and various colors and effects appearance. Limited to the characteristics of low electrical conductivity, high outgassing and poor temperature resistance of wood-based panels, higher requirements are put forward for powd...
