Abstract

The invention relates to a high-temperature-sintering varnish cured under an LED-UV cold light source and a preparation method of the varnish. In the method, composite resin and an active diluent anda plurality types of surfactants are employed; a plurality of small-molecular substances are added; the resins, in different types, are respectively treated; and then a stepwise temperature-increasinguniformly stirring and mixing process is carried out. The method not only can improve flexibility and glossiness of the varnish during preparation of printing ink and enhance the adhesion force whenthe varnish, after printing with inorganic pigments, is transferred on a base material, but also improves weather resistance varnish during preparation of the printing ink. The varnish has excellent anti-heat aging and anti-cold aging effect, ultraviolet aging resistance, waterproof effect and acid and alkali resistance. Meanwhile, wearing resistance, tensile rate and hardness of the varnish during preparation of the printing ink are enhanced.

Description

technical field [0001] The invention relates to a high-temperature sintered varnish cured by an LED-UV cold light source and a preparation method thereof, belonging to the technical field of inks. Background technique [0002] Varnish, also known as cold printing oil, blending oil, blending oil, connecting oil, blending paste, etc., is mainly used to adjust the adhesion and printability of ink. [0003] High-temperature varnish is to add inorganic pigments to high-temperature varnish in a certain proportion, and then mix and grind to prepare high-temperature ink; the prepared inks of various colors are printed on small film decals by printing, also known as water transfer On decal paper (a special paper pre-coated with water-soluble glue), and then soaked in water and wet, the pattern is transferred and attached to the surface of the object or printed and thermal transfer film, and then transferred to ceramics or glass by thermal transfer superior. [0004] Yet this known ...
