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' canvas with coating of vinyl acetate-ethylene copolymer 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 for the bottom layer, the middle layer and facing layer; painting the bottom coating and stoving; painting 1-3 middle coating and stoving; and painting 1 or 2 facing coating and stoving to obtain the product. The artists' canvas has fine smooth and homogeneous coating, improved use performance, no oil permeation, high water resistance, and other advantages.

Description

technical field [0001] The invention relates to a non-filler vinyl acetate-ethylene copolymer compound coated art oil painting cloth and its production process, specifically for painting artists, suitable for oil painting, acrylic painting and gouache painting, and can also be used for decoration, The decoration 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 t...
