Water-based oil polish for cartons and preparation method thereof

Abstract

The invention discloses a water-based oil polish for cartons. The invention is characterized in that the oil polish is prepared from the following raw materials in parts by weight: 10-20 parts of water-based alkyd resin, 40-60 parts of modified styrene-acrylic emulsion, 0.5-1 part of polyvinylpyrrolidone, 6-8 parts of polyethylene wax emulsion, 1-2 parts of isopropyl palmitate, 1-2 parts of glyceryl caprylate-caprate, 1-2 parts of cotton oil, 1-2 parts of peanut protein, 0.1-0.2 part of sodium benzoate and 10-15 parts of water. The water-based oil polish has the advantages of favorable hardness, favorable wear resistance, favorable impact resistance, excellent water resistance, excellent corrosion resistance, favorable temperature resistance, high glossiness and high drying rate, and is suitable for printing cartons.

Description

technical field [0001] The invention relates to printing processing technology, in particular to a water-based varnish for cartons 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...

AI Technical Summary

Problems solved by technology

Solvent volatilization during the traditional solvent-based varnish glazing operation not only pollutes the environment, but also causes certain damage to human health. It is difficult to meet the increasingly stringent standards for hygiene, environmental protection, and labor protection. Therefore, environmentally friendly water-based varnishes have gained More and more attention, with good development prospects and market potential

The existing problems of water-based varnish mainly include the price and comprehensive performance of the product. The biggest problem in product performance is to improve the weather resistance of the product, such as abrasion resistance and water resistance.
