Abstract

The invention relates to waterborne environment-friendly varnish for tempered glass and belongs to the field of new materials. The waterborne environment-friendly varnish for tempered glass is made from, by mass, 1-95% of water, 0-95% of an environment-friendly solvent, 0.1-5% of a film-forming agent, 0.1-2% of a defoaming agent, 0.1-5% of a wetting dispersant, 0.1-2% of a leveling agent, 2-30% ofa binder, and 1-10% of an anti-settling agent. The waterborne environment-friendly varnish for tempered glass uses water as a basic solvent and accordingly is economical and environmentally friendly;the waterborne environment-friendly varnish for tempered glass has good dispersion with inorganic glass pigments; a film of the waterborne environment-friendly varnish for tempered glass is flat andbright, is tolerant to low temperature weathers and good in leveling property; equipment, tools, containers, a ground, clothes and otherness in contact with the varnish can be washed with tap water.

[0037] Defoamer: 0.1%,
[0038] Wetting and dispersing agent: 0.1%,
[0039] Leveling agent: 0.1%,
[0040] Adhesive: 2%,
[0041] Anti-settling agent: 1.6%.
[0042] The water is distilled water with a neutral pH.
[0043] The environmentally friendly solvent is glycerol.
[0044] The said film forming agent is DOW PALPAD C zero VOC film forming aid.
[0045] The defoamer includes the polyether foam inhibitor DOWFAX DF103.
[0046] The wetting and dispersing agent is TEGO DISPERS 735W.
[0047] The leveling agent includes BYK333, a water-based silicone leveling agent.
[0048] The adhesive is water-soluble acrylic resin.
[0049] The anti-settling agent is water-soluble peach gum.
[0050] The water-based varnish and inorganic glass pigment BN5715 black prepared in this example (manufacturer: Zibo Baojing Ceramic Glass Pigment Development Co., Ltd.; product specification: zinc-based lead-free black; product batch: 20171019; product fineness D90 = 5.5 microns ) According to the water-based ink: inorganic glass pigment=1:3 (mass ratio), mix and pre-stir, and then grind through a three-roll mill to obtain water-based ink. The viscosity of the ink is 5200mPa·s (25℃, 7# rotor, 100rpm , Malvern Rheometer, UK), low viscosity, printed on glass by 250 mesh screen, visually inspect the ink surface to form a film and mirror level, the back of the glass is irradiated with a fluorescent lamp, visually inspect the ink printing layer without pinhole trachoma and other hollow points.
[0051] The water-based inkjet and inorganic glass pigments of this example wet well, the water-based ink has good fluidity, the film is smooth when coated on the glass surface, it is not easy to dry in the air for a long time, and it has strong moisture retention, which is suitable for the hot weather conditions in the south.
