Abstract

The present invention discloses a colored transparent glass paint, its preparation method and application. Its composition includes (by weight portion) 6-9 portions of nitro-cotton, 9-12 portions of polyketone resin, 15-25 portions of castor oil modified alkyd resin, 8-12 portions of thermoset acrylic resin, 1-2 portions dibutyl phthatate, 1-2 portions of tritolyl phosphate, 5-7 portions of solvent-type metal complex dyestuff and proper quantity of volatile mixed solvent. Said paint can be coated on the glass surface, under the condition of 120-150 deg.C it can be baked for 3-5 min and can be solidified to form film.

Description

technical field [0001] The invention relates to a colored transparent glass coating, in particular to a colored transparent glass coating and a preparation method thereof, which are mainly applied to the surfaces of decorative glass and glass products. Background technique [0002] Currently, alkyd resins are one of the most widely used varieties of synthetic resins and are most commonly used in colored glass coating applications due to their good properties. However, the biggest disadvantage of alkyd resin is that the coating film is soft, the water and alkali resistance is poor, and the drying speed is slow (the surface dryness is greater than 4h, and the actual dryness is greater than 15h). There are more OH and CO remaining in the alkyd resin 2 H group, these groups can make the coating film made of alkyd resin have good adhesion, but seriously affect the water resistance of the coating film; the ester group on the resin molecular chain also makes the coating film not r...
