Problems solved by technology

However, this type of glass printing varnish has the following disadvantages: first, it uses polar organic compounds as solvents, and they will still volatilize into the atmosphere during the use of the ink, which does not fundamentally solve the problem of environmental pollution by organic solvents; secondly, The use of a large number of organic solvents increases the cost of the product and wastes resources; in addition, the adhesion of this type of ink on glass is worse than that of traditional oil-based inks, which cannot meet the performance requirements of glass printing on special occasions.

Abstract

The invention discloses a non-solvent type water-soluble varnish and a preparation method thereof. The non-solvent type water-soluble varnish is a liquid formed by mixing non-solvent type water-soluble liquid resin with a curing agent. The preparation method comprises the following concrete steps of taking a water-soluble component, a hydrophobic component, an active organosilicon composition andthe like as main raw materials, synthesizing the non-solvent type water-soluble liquid resin through bulk copolycondensation reaction in the presence of catalyst, well mixing the curing agent with the resin and then obtaining the transparent non-solvent type water-soluble varnish. The preparation of the non-solvent type water-soluble varnish uses no organic solvent, and is simple in process and less equipment investment. The varnish is friendly to environment and can be widely used in the glass printing industry.

Description

technical field [0001] The invention belongs to the technical field of materials and fine chemicals, and relates to a solvent-free water-soluble varnish and a preparation method thereof. Background technique [0002] With the rapid development of the automobile industry, architectural decoration industry and transportation industry, the demand for glass printing inks is increasing year by year, and the quality requirements for inks are also getting higher and higher. At present, most of the inks used in the glass printing industry are obtained by mixing oil-soluble resin varnishes with pigments and fillers and other additives. The organic solvents used in large quantities in such products not only waste energy and resources, but also cause a large amount of organic solvents in the process of production and use. The solvent volatilizes into the atmosphere, causing serious harm to human health and the environment; in addition, it is difficult to clean equipment and utensils du...
