AI Technical Summary

Benefits of technology

This patented technology allows for efficient use of UV light while producing quality coatings on various materials such as wood products without harming their properties like color strengthening agents (CAs). Additionally it provides environmental benefits due its ability to produce paints at lower costs compared to conventional techniques.

Problems solved by technology

This patented technical solution described in this patents relates to improving the durability and strength of plasma display panels while reducing harmful chemical vapor emission levels compared to current methods like painting. These techniques involve forming layers over plastisol films instead of hardening them before applying paints onto surfaces they come off. To improve these technologies, there needs to develop a new type of coating material without containing any heavy metals or expensive components.

Embodiment 1

[0066] Table 1

[0067]

[0068]

[0069] Add the diluent (deionized water / ethanol = 1 / 1 (volume ratio)) to the Iwata cup of the composition obtained above for about 10 seconds, spray it on the plastic substrate with an air spray gun, and then carry out 5 minutes in an oven at 60°C. ~10 minutes of pre-bake, then, through the medium pressure mercury lamp (800mJ / cm 2 ) for exposure. Then, the substrate with the coating film after exposure is subjected to a physical property test.

[0070] The results of the physical property test are as follows:

[0071] Film thickness: 8~15μm

[0072] Adhesion between coating film and substrate: 100 / 100

[0073] Coating film hardness: ≥H

[0074] Coating gloss: 70

[0075] Chemical resistance of the coating film: pass (no scratches on the appearance, no peeling off)

[0076] Coating film heat resistance: pass

[0077] Appearance: flat, with a silver semi-gloss effect

Abstract

The invention relates to an ultraviolet-curable water-based colored paint composition which comprises water-based oligomer containing at least one unsaturated double bond, a water-based medium, a photoinitiator, an optional water-based thermoplastic resin and pigments. The water-based paint composition provided by the invention can be used for obtaining a high-performance coating with abundant colors in a one-time construction mode. Compared with the traditional two-layer or three-layer application mode, the invention enhances the production efficiency, reduces the energy dissipation, lowers the preparation cost, and has the advantages of less waste generation, low content of volatile organic compounds, and low environmental pollution.
