Problems solved by technology

Most water-based acrylate copolymer emulsions are lipophilic. After coating with acrylic system coatings, pigment diluents such as linseed oil are easy to diffuse and penetrate; the coating system has a large amount of film-forming substances, and the system has high gloss (a kind of linseed light oil canvas , 201510790351.1; a high-gloss chemical fiber oil canvas and its preparation method, 201810278361.0), which cannot present a matte effect; most products do not have anti-ultraviolet and anti-mildew effects, and are prone to yellowing and chalking under sunlight or ultraviolet radiation, and are easy to The growth of mold and algae will affect the quality of the canvas and even the painting

Abstract

The invention relates to a waterborne matte environment-friendly canvas coating material with high weather resistance. The waterborne matte environment-friendly canvas coating material is prepared from deionized water, cellulose, dispersant, a wetting agent, a defoaming agent, AMP-95, titanium dioxide, diatomite, heavy calcium, gaseous silicon dioxide, waterborne acrylate copolymer emulsion, film-forming additive, cosolvent, photocatalyst material, epoxy silane, ultraviolet absorber, bactericide, mildew inhibitor and thickening agent. The waterborne matte environment-friendly canvas coating material with high weather resistance overcomes the defects that the existing canvas coating material is not environment-friendly, is high in VOC and high in gloss, and does not have long-term weather resistance and mildew resistance and the like. The matte environment-friendly canvas coating material is low in gloss, photosensitive and soft; the matte environment-friendly canvas coating material has appropriate oleophobic effect, and the pigment diluent such as linseed oil is not easy to diffuse and permeate; the affinity with the a base material and pigments is high, and the adhesion is good;the waterborne matte environment-friendly canvas coating material is odorless, environment-friendly, low in -VOC, capable of removing formaldehyde, and capable of meeting the EN71-9 standard requirements; and a coating of the waterborne matte environment-friendly canvas coating material is resistant to yellowing, excellent in weather resistance and good in mildew resistant effect.

Description

technical field [0001] The invention relates to a canvas coating material, in particular to a water-based matte highly weather-resistant and environment-friendly canvas coating material and a preparation method thereof. Background technique [0002] Canvas is made by coating water-based or oil-based paint on cotton gauze, linen and other substrates. At present, most of the canvas coatings use PVA (a scratch-resistant oil canvas and its production method, 201810278355.5; a high-gloss chemical fiber oil canvas and its preparation method, 201810278361.0), propylene glycol butyl ether (an ink-absorbing vertical dry canvas, 201310679748.4) and other non-woven fabrics. Environmentally friendly material, high VOC, big smell. Most water-based acrylate copolymer emulsions are lipophilic. After coating with acrylic system coatings, pigment diluents such as linseed oil are easy to diffuse and penetrate; the coating system has a large amount of film-forming substances, and the system h...
