Problems solved by technology

The defect of this white-coated art canvas is that the compactness of the coating film is not ideal, and back seepage and oil absorption are often prone to occur during painting; because it contains more solid powder without fillers, it is prone to cracking and cracking of the coating and flaking; white coating tends to yellow
These defects affect the performance and shelf life of the product

Abstract

The invention relates to a no-filling material polyvinyl alcohol coating layer art canvas and the producing technology. It uses polyvinyl alcohol as main raw material to make bottom, middle and covering coating material. Coating bottom layer on the bottom canvas, drying; coating middle coating layers, drying; coating covering layers, drying; and the product would be gain. The invention improves the softness, compactness and mechanical strength of the coating film, and would not cause loose by the alteration of temperature and humidity.

Description

technical field [0001] The invention relates to a non-filler polyvinyl alcohol composite coated art oil painting cloth and its production process, specifically for painting artists, suitable for oil painting, acrylic painting, gouache painting, and can also be used for decoration and decoration. It belongs to the technical field of painting supplies. Background technique: [0002] Before the present invention was made, in prior art, artist's painting usually adopts traditional white coated canvas. It is mainly to apply white coating material directly on the base fabric. The white coating material adopts polymer emulsion such as polyvinyl alcohol, ethylene acetic acid homopolymer emulsion, styrene-acrylic ester copolymer emulsion and pure acrylate copolymer emulsion as one-component or two-component emulsion as coating base A large number of fillers such as titanium dioxide, lithopone, talcum powder, calcium carbonate, zinc oxide, etc. are mixed. Then apply the coating mat...
