AI Technical Summary

Technical Problem

In existing technologies, water-based varnishes cannot simultaneously achieve both low gloss and hot stamping effects, resulting in poor performance of printed materials in the hot stamping process.

Method used

The matte oil formulation, composed of a specific ratio of water-based acrylic resin, acrylic film-forming emulsion, acrylic non-film-forming emulsion, self-crosslinking acrylic emulsion, wax emulsion, matting powder, matting powder dispersant, leveling agent, and wetting agent, ensures that the matte oil has low gloss and good hot stamping performance by precisely adjusting the particle size and the effect of additives.

Benefits of technology

It achieves the low-gloss effect of matte varnish while possessing excellent hot stamping performance, enhancing the visual impact and abrasion resistance of printed materials.

Abstract

This invention discloses a matte oil suitable for hot stamping and its preparation method. The matte oil raw materials comprise the following components by weight percentage: 20%–30% water-based acrylic resin, 15%–20% acrylic film-forming emulsion, 15%–25% acrylic non-film-forming emulsion, 10%–20% self-crosslinking acrylic emulsion, 3%–6% wax emulsion, 5%–10% matting powder, 0.3%–0.5% matting powder dispersant, 0.5%–1.5% leveling agent, 0.5%–1% wetting agent, 0.04%–0.1% defoamer, and the balance being deionized water. The wax emulsion is a microcrystalline wax emulsion; the matting powder is amorphous silica with a particle size of 2 μm–4.3 μm; and the leveling agent is a modified polyacrylate adsorbed onto silica. The matte oil of this invention has low matteness and excellent hot stamping effect.
