Problems solved by technology

Solvent-type and alcohol-soluble calender oils contain a large amount of organic solvents, which have a strong smell, which is not conducive to safe production and improvement of working conditions, and is easy to pollute the environment. The solid content of the coating is low and the viscosity is high; while the existing emulsion type calender The temperature resistance of varnish is not good, and it will cause sticking on the high temperature calender at 130-150 ℃

Abstract

The invention discloses aqueous calendering oil for the glazing of calendaring technology of paper printing products, which comprises the following components in portion by weight: 90 to 95 portions of aqueous acrylic ester resin emulsion, and 4 to 8 portions of wax emulsion. The aqueous calendering oil for the glazing of the calendaring technology of the paper printing products is applicable to high-temperature calendaring technology with a temperature more than 130 DEG C, thereby ensuring that printing products achieve higher gloss and better mirror effect. In addition, the aqueous calendering oil has good film forming property, does not need to add a film forming additive, can take water as a diluting agent, does not need alcoholic solvents, and radically overcomes the defect that the prior technology uses an organic solvent. The product has no toxicity, does not contain organic solvents, is safe and environment-friendly, is suitable for the high-temperature calendaring technology, obtains higher gloss, and has the advantages of excellent wear resistance, smooth surface, moisture protection and water resistance, aging resistance, high solid and low viscosity.

Description

Technical field [0001] The invention relates to a water-based calendering oil for the calendering process of paper printed matter. technical background [0002] The paper printed matter polished by the calendering process is a kind of printed paper product with high gloss mirror effect. It is used for high-end trademark packaging products, product manuals, artistic pictures, postcards, playing card boxes and other printed matter. Because of its lower cost and less plastic The amount of film has gradually replaced the expensive glass cardboard and paper-plastic composite prints. In order to make paper prints produce high-gloss mirror effects, it is necessary to calender the prints coated with calender oil. That is, the glazing method that combines the application of the thermoplastic calendering paint and the calendering machine is adopted, that is, the calendering paint is first coated on the paper printed matter with an ordinary glazing machine, and then it is heated by the stai...
