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 present invention belongs to the field of drawing article technology, and is especially one kind of artists' color canvas with coating of PVA and no filler suitable for oil painting, propylene drawing, gouache and decoration and its production process. The artists' canvas producing process includes compounding the coating materials with PVA solution, styrene-acrylate copolymer emulsion, vinylacetate-ethylene copolymer emulsion, pigment slurry, etc for the bottom layer, the middle layer and facing layer; painting the bottom coating and stoving; painting 1-3 middle coating and stoving; andpainting 1 or 2 facing coating and stoving to obtain the product. The present invention adopts sandwiched structure coating technique, and the artists' canvas has stable performance, good color, highcoating strength, no oil permeation and other advantages.

Description

technical field [0001] The invention relates to a non-filler polyvinyl alcohol compounded color-coated art oil canvas and its production process, specifically for painting artists, suitable for oil painting, acrylic painting, and gouache painting, and can also be used for decoration and decoration The invention 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. White coating materials use polymer emulsions such as polyvinyl alcohol, ethylene acetic acid homopolymer emulsions, styrene-acrylate copolymer emulsions, and acrylate copolymer emulsions with one-component or two-component emulsions as coating gum bases. Made with a mix of multiple fillings. Then apply the coating material on the base cloth to make art oil canvas. The defect of this kind of w...
