Embodiment Construction

[0030] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0031] The basic preparation method is as follows: use an electric heating reaction pot to stir the mixed solvent of polyethanol resin, white filler, dispersant, anti-mold and fungicide, and diluent water according to the formula. After stirring for 10 hours, use a mixer to disperse the carbonic acid at high speed according to the formula. Calcium nano-slurries are dispersed and stirred at a speed of 500 rpm in a mixed solvent for 1 hour, and then the film-forming polymer resin solution and the remaining other coating additives are added to continue at a speed of 300 rpm. Stir until the particles are uniformly dispersed in the system to obtain the nanocomposite canvas paint of the present invention. Among them, the mixer can choose the SJ1200 mixer produced by Jiangyin Fine Chemical Machinery Co., Ltd., the weight percentage of nano calcium ca...

Abstract

The invention relates to a nanometer compound coating material of painting canvas, which is characterized in that the compositions which contain the following weight proportion as polyvinyl alcohol resin 2-4 parts, film former macromolecule resin emulsion 8-30 parts, nanometer calcium carbonate pulp body 1-20 parts, white filling 5-40 parts, auxiliary agent of coating material 1-8 parts, and water namely deflocculating agent 20-30 parts, wherein the film former macromolecule resin emulsion is one or more than one of propyl benzene emulsion, micron-grade pure acroleic acid resin emulsion, and ultra-violet self-cross bonding pure acroleic acid resin emulsion, and the weight percentage of nanometer calcium carbonate in nanometer calcium carbonate pulp body is 48-52%. Compared with the prior art, the invention has the advantages that base material chooses nanometer calcium carbonate pulp body and film former macromolecule resin emulsion with high performance as coating material, since the diameter of nanometer calcium carbonate is greatly less than normal film forming matter, thereby when the coating material is filming, nanometer calcium carbonate is filled between the film forming matter and particle crack, and the degree of compactness and oil permeation resistance of coating material are improved.

Description

technical field [0001] The invention relates to a nanocomposite canvas paint which can be applied to the surface of canvases with textures such as pure cotton, pure linen, cotton-linen blended, polyester-cotton, polyester-linen, pure polyester, and rayon. Background technique [0002] The use of canvas began with the Venetian painters in the Renaissance in the 13th century. The canvas works drawn by the painters are all created with life and inspiration. The painters have been working hard to pursue the expressiveness of the canvas. The quality of the layer process is the key to determine the expressiveness and the quality of the canvas. The canvas coating material requires strong adhesion to the canvas, and has the characteristics of oil seepage resistance, stretch resistance, no cracking, and aging resistance. It can make the canvas works intact after a long period of preservation, and leave them for future generations to appreciate. [0003] Identification of canvas qual...
