Aqueous polyurethane latex composite compounding coat art canvas and producing technique thereof

Abstract

The invention relates to a water-based polyurethane emulsion compound coated art oil canvas and a production process thereof, belonging to the technical field of painting supplies. It is characterized in that hydroxypropyl cellulose is swollen with half of the formula amount of pure water, heated, stirred and dissolved; mixed with water-based polyurethane emulsion, styrene-acrylate copolymer emulsion, glycerin, ethanol, sodium benzoate and stirred evenly to form a gel; The powder and titanium dioxide are wetted with the remaining amount of purified water in the formula, mixed with the above glue, stirred evenly at room temperature to form a coating slurry; then coated with three to five layers of the coating slurry on the base cloth, dried and dried as finished product. The invention obviously increases the softness, abrasion resistance, impact resistance and weather resistance of the product. And it has the elasticity similar to the skin film and eliminates the adhesion phenomenon of the surface layer of the coating, making the product coating soft and dense, not easy to crack and peel off the coating, preventing the diffusion and back seepage of oil paint during painting, and optimizing the performance of the product and shelf status.

Description

technical field

[0001] The invention relates to a water-based polyurethane emulsion compound coated art oil canvas and a production process thereof, in particular to be used for painting by painting artists and lovers. The utility model is suitable for oil painting, acrylic painting and gouache painting, and belongs to the technical field of painting supplies. Background technique

[0002] In the prior art, the artist's painting usually adopts to be coated with more than 3 layers of white coating materials on the base substrate and dry to make art oil canvas. The white coating material is made of polymer solution or emulsion, such as polyvinyl alcohol, ethylene acetic acid homopolymer emulsion, polyacrylate copolymer emulsion, one-component or two-component or more emulsion compound, as the coating gum base, add a large amount Fillers such as titanium dioxide, lithopone, talcum powder, calcium carbonate, zinc oxide, etc. are mixed. Then apply the coating material to the ba...
