Problems solved by technology

The high-temperature sintering process temperature is 600-800°C, which consumes a lot of energy and has high production costs; most of the pigments used in high-temperature sintering inks are high-temperature lead-containing oxides with high heavy metal content, which is seriously harmful to the human body
Low-temperature curing solvent-based inks are developed on the basis of sintered inks, with low energy consumption and environmentally friendly pigments, but low-temperature curing inks have weak adhesion to substrates, low hardness, and acid, alkali, water, and alcohol resistance. not ideal
The bonding effect between glass and commonly used polymers is weak, so even if a polymer with strong adhesion such as epoxy resin is used as the binder, the peeling resistance of the ink is still not ideal. After the ink with poor adhesion is initially dried, the ink film will Easily scratched and scratched

Abstract

The present invention discloses benzoxazine-modified epoxy glass printing ink and preparation method and application thereof. The preparation method comprises dissolving epoxy resin in the organic solvent, evenly stirring, to obtain liquid epoxy resin, based on the mass portion, blending 60 to 80 parts of liquid epoxy resin with 8 to 20 parts of benzoxazine, heating and stirring the resultant blendings at the temperature of between 60 and 80DEG C for 10 to 25 minutes to be uniformly dissolved to obtain the ink binder; evenly mixing the resultant ink binder, 0.1 to 2 parts of defoamer, 1 to 4 parts of leveling agent, 1 to 3 parts of thickener, 8 to 15 parts of inorganic pigments, 0.1 to 1 parts of dispersants and 1 to 5 parts of inorganic filler, grinding the resultant mixture until the fineness is below 16 Mum to obtain the finished printing ink. The printing ink provided by the invention, a curing agent and a coupling agent are mixed and cured, the cured mixture is directly printed onto the glass panel, which is placed in oven for cross-linking curing to obtain the ink film with good adhesion, high hardness and excellent solvent resistance.

Description

technical field [0001] The invention relates to an epoxy resin glass ink, in particular to a benzoxazine-modified epoxy resin glass ink for decorating glass surfaces and a preparation method thereof. Background technique [0002] At present, glass has become an indispensable material in modern life. People have higher and higher requirements for the appearance and packaging of glass products. The personalized design of glass appearance has become the main development trend, and glass screen printing ink is to make glass products An important means of diversifying the appearance of colors. [0003] Over the years, common glass decoration processes mainly include high-temperature sintering screen printing process and solvent-based low-temperature curing screen printing process, both of which have certain shortcomings. The high-temperature sintering process temperature is 600-800°C, which consumes a lot of energy and high production costs; most of the pigments used in high-tem...
