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

This invention relates to a skin coat built color polyvinyl alcohol painting cloth without filler and its preparation method. It is specially used to paint by painter, and it belonged to the article of painting. The skin coat without filler is composed of the liquid of polyvinyl alcohol, pure copoly acrylate paste, the copolymer of vinyl acetate and ethane, graining paste, glycerine and sodium benzoate. These mixtures build the paint of bottom and middle skin coat. Then coating the bottom layer on the basis coat and drying. Secondly coating one to three layer middle coats and drying. At last coating one to three layer paste and drying to get the product. This invention adopts different nature high molecule polymer to build the paint of bottom and middle skin coat, and combines the coated technology of 'sandwich' the function of the coat is stable, the colors is colorful. The intensity of coat membrane is high, there isn't colors migration, the membrane of the coat is intensity and theoil can not leak out. It can not lead to the crack, fold crack and breaking off of the coat, and it can not collapse because of the temperature difference and change of moisture. The light-resistant of the coat is good, and it is not easy to become yellow to affect the shelf state of the product.

Description

technical field [0001] The invention relates to a polyvinyl alcohol compounded color-coated oil canvas with no filler in the overcoat and its production process. Specifically, it is used for painting by painters, suitable for oil painting, acrylic painting, and gouache painting, and can also be used for decoration. , decoration, belonging 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 the coating base. Made with a larger quantity of fillings mixed. Then apply the coating material on the base cloth to make art oil c...
