Problems solved by technology

[0003] However, after spraying the varnish, in order to make the surface of the paper dry quickly and without sticking, most of the processes need to be heated and dried. Since most of the varnishes are mixed with an oily base at this stage, the heating temperature should not be too high. If the temperature is too high, it will not only cause the printing surface to be scorched, but also cause the danger of ignition. It is necessary to use low temperature and long-term drying to dry the varnish, which will result in a longer drying time and have a certain impact on production efficiency.

Abstract

The invention discloses a high temperature-resistant anti-adhesion over-printing varnish, The over-printing varnish is prepared from the following components in parts by mass: 60-80 parts of styrene-acrylic acid copolymerized emulsion, 5-10 parts of waterborne self-crosslinking acrylic emulsion, 8-10 parts of waterborne wax emulsion, and 6-10 parts of solvent. Through using high temperature-resistant components of styrene-acrylic acid copolymerized emulsion, waterborne self-crosslinking acrylic emulsion and waterborne wax emulsion, a waterborne over-printing varnish, which can be dried under high temperature and has a high abrasion performance, can be obtained; meanwhile, as the varnish is waterborne over-printing varnish, therefore having environment-friendly characteristic.

Description

technical field [0001] The invention relates to the field of printing inks, in particular to a high-temperature-resistant anti-adhesion varnish. Background technique [0002] In the manufacturing process of cigarettes, in order to ensure the appearance of cigarette packaging or cigarette filters, varnish is used after printing to make the appearance more gorgeous and increase the physical properties of the surface, such as hardness, durability Abrasiveness, moisture resistance and gloss, etc., and it can also make up for some defects in the printing process, so that some printing defects will not be obvious. [0003] However, after spraying the varnish, in order to make the surface of the paper dry quickly and without sticking, most of the processes need to be heated and dried. Since most of the varnishes are mixed with an oily base at this stage, the heating temperature should not be too high. If the temperature is too high, it will not only cause scorching of the printing...
