Thermal-transfer coloured crystal glass and preparation method thereof

Abstract

The invention provides thermal-transfer coloured crystal glass which can be used for printing fine texts and images and can realize scale industrial production and a preparation method of the thermal-transfer coloured crystal glass. The preparation method comprises the following steps of: carrying out corona treatment on a surface of a biaxially oriented polyester (BOPET) film; coating organic silicon resins, acrylic resins and a printing oil ink layer in a layered mode and coating a polyester and epoxy mixed resin layer to form a thermal-transfer coating film; hot-pressing a coating on the thermal-transfer coating film by hot-pressing equipment, and transferring the coating to the back of the glass; and carrying out heating and solidification to form thermal-transfer flat or curved coloured crystal glass. The thermal-transfer coloured crystal glass is characterized in that: the oil ink layer is high in high combination firmness, colour consistency is good, temperature resistance and weathering resistance are achieved, a long-term non-discolouring effect is achieved, the colour is uniform, the printing of the texts and the images is fine, and resolution reaches 600 dots per inch (dpi).

Description

Technical field [0001] The invention relates to a thermal transfer color crystal glass and a preparation method, in particular to a thermal transfer flat plate or curved surface color crystal glass and a preparation method, and belongs to the field of glass processing and printing. technical background [0002] With the wide application of glass materials in the appearance decoration and panel materials of home appliances, higher requirements are put forward for the printing and processing of the glass itself. Traditional glass sandblasting and etching can no longer meet the requirements of modern industrial products for glass decoration. The processing technology of silk-screen glass has great limitations, which cannot meet the requirements of modern glass products that require fine pattern printing, rich layers, and diversified effects.

Problems solved by technology

[0002] With the wide application of glass materials in home appliance exterior decoration and panel materials, higher requirements are put forward for the printing and processing of glass itself. Traditional glass sandblasting and etching can no longer meet the requirements of modern industrial products for glass decoration. Spraying and The processing technology of silk-screen glass has great limitations, and it cannot meet the requirements of modern glass products that require fine pattern printing, rich layers, and diverse effects.

With the development of digital technology, although digital printing glass has solved the requirements of fine graphics and rich layers, its production efficiency is low and it is not suitable for large-scale industrial production. Its pigments are difficult to meet the requirements of temperature resistance, ultraviolet light and durability.
