Abstract

The invention discloses an anti-ageing water-based varnish. The anti-ageing water-based varnish is characterized by being prepared from the following raw materials in parts by weight: 60-80 parts of modified styrene-acrylic emulsion, 0.05-0.1 part of magnesium ascorbyl phosphate, 0.3-0.5 part of inositol hexaphosphate, 3-5 parts of polyethylene wax emulsion, 3-5 parts of white mineral oil, 1-2 parts of peanut protein, 0.1-0.2 part of sodium benzoate, 0.2-0.4 part of diacetyl tartaric acid ester of mono(di)glycerides, 0.01-0.02 part of propyl gallate and 10-15 parts of water. The water-based varnish disclosed by the invention is good in hardness, wear resistance, impact resistance, water resistance, and corrosion resistance; meanwhile, the product is good in ageing resistance, resistant to yellowing, high in weather resistance and good in protection performance.

Description

technical field [0001] The invention relates to printing processing technology, in particular to an anti-aging water-based varnish and a preparation method thereof. Background technique [0002] In recent years, with the progress of the economy and the continuous improvement of people's living standards, the quality requirements for printed matter and the environmental protection requirements of the printing industry have continued to increase. Glazing is one of the most widely used processes in the printing industry, and it is an indispensable part of the printing industry. It is imperative to develop and improve it. Varnish is a colorless, transparent or translucent ink. When glazing, a layer of varnish is coated on the surface of the printed matter, combined with subsequent processes to form a transparent and bright layer on the surface of the printed matter to achieve the effect of decoration and protection of the printed matter. . Solvent volatilization during the tra...
