Problems solved by technology

At present, water-based varnishes are widely used in foreign countries, and domestic manufacturers of water-based varnishes are also gradually increasing, but the quality is uneven, the gloss is not high enough, and the stability is not good, and even precipitated substances appear; With the continuous improvement of product glazing requirements, especially for high-end paper products, the demand for water-based varnishes with good wear resistance and high gloss is increasing
[0003] Traditional water-based varnishes, due to the poor rigidity of molecular structure and poor dispersion of additives, lead to poor wear resistance of traditional water-based varnishes, and the traditional water-based varnishes have poor oxidation resistance. After a period of use, yellowing, cracking and peeling will occur, which will seriously affect the use of the product

Abstract

The invention discloses wear-resistant and anti-aging waterborne glazing oil and a preparation method thereof, and relates to the field of novel environment-friendly high polymer materials. The preparation method comprises steps as follows: PAH-D microgel is prepared from polyacrylamide hydrochloride, glucan and metal powder together, pretreated tetratitanate is soaked with a PAH-D microgel dispersion liquid and a poly 4-vinylbenzenesulfinic acid sodium salt solution respectively, and an additive is prepared; acrylic resin is mixed with a mixed surfactant, potassium persulfate and water are added, after a stirring reaction is performed, styrene, butyl acrylate and ammonium hydroxide are added, a blank is prepared by a mixing reaction, finally, the blank is mixed with silicone oil, the additive is added, and the wear-resistant and anti-aging waterborne glazing oil is prepared. The prepared wear-resistant and anti-aging waterborne glazing oil has excellent wear resistance and oxidation resistance.

Description

technical field [0001] The invention relates to the field of novel environment-friendly polymer materials, in particular to a wear-resistant and anti-aging water-based glazing oil and a preparation method thereof. Background technique [0002] Varnish is used as a decorative and protective coating on printed paper products. It is widely used in food, cosmetics, pharmaceuticals and other industries because of its high gloss, water resistance, wear resistance, and good weather resistance. At present, a large number of solvent-based varnishes (pollution to the environment) and UV varnishes (expensive) are still used in the market. The requirements for printing effects are different, and water-based varnishes have already made the road to diversification. At present, water-based varnishes are widely used in foreign countries, and domestic manufacturers of water-based varnishes are also gradually increasing, but the quality is uneven, the gloss is not high enough, and the stabil...
