Abstract

The invention relates to a water-based polyurethane emulsion compounded colored coating art canvas and a manufacturing technique, in particular to a canvas for painting artist and hobbies to paint, which belongs to the technical field of painting articles. And the process for manufacturing comprises getting hydroxypropyl cellulose to swell, heat up, stir and dissolve with half purified water of the total amount, and mixing and evenly stirring water-based polyurethane emulsion, styrene monomer- acrylate copolymer emulsion, graining paste, glycerin, alcohol and sodium benzoate, getting lithopone powder and calcium carbonate to mix with the upper glue solution after wetting with the residual water of the total purified water, evenly stirring to be coating slurry in normal temperature, and then applying coating slurry on primary backing, drying and baking to be end products. The service performance of the art canvas of the invention is greatly improved, since aqueous polyurethane emulsion (APU) is utilized in the formula, therefore the thermoplasticity polyurethane emulsion has the advantages of easy filming, low temperature resistance, excellent elasticity, flexibility and the like.

Description

technical field [0001] The invention relates to a water-based polyurethane emulsion compound color coated art oil canvas and its production process, specifically for painting artists and lovers; it is suitable for oil painting, acrylic painting and gouache painting, and can also be used for interior decoration and decoration. Huang belongs to the technical field of painting supplies. Background technique [0002] In the existing technology, the artist's painting usually adopts to be coated with more than 3 layers of colored coating materials on the base substrate and dry to make the art oil canvas. The color coating material is made of polymer solution or its emulsion, such as polyvinyl alcohol, ethylene acetic acid homopolymer emulsion, polyacrylate copolymer emulsion, one-component or two-component or more emulsion compounding, as the coating base, adding more Quantitative fillers such as titanium dioxide, lithopone, talcum powder, calcium carbonate, zinc oxide, etc. are ...
