Abstract

The invention discloses a universal smooth clay drawing board which is prepared through the processes: 180-220 parts of deionized water, 1.5-2.5 parts of defoaming agent, 18-22 parts of propylene glycol and 4.5-5.5 parts of dispersing agent into a reaction kettle, and uniformly stirring all the components; adding 145-155 parts of titanium dioxide, 140-160 parts of kaoline and 180-220 parts of talcum powder, dispersing for 1h, adding 340-360 parts of pure acrylic emulsion, and uniformly stirring; adding a multifunctional assistant AMP-95 to adjust the pH value to 7.0, and adding the 1.5-2.5 parts of defoaming agent, 9-11 parts of film-forming additive, 45-55 parts of thickening agent ASE-60 and 1-1.5 parts of thickening agent TT935 while stirring to obtain a coating for curtain coating; and carrying out curtain coating on a base material to obtain the universal smooth clay drawing board. A clay coating of the drawing board is sunproof, acid-resistant and corrosion-resistant so as to ensure that a work is not cracked or faded after being stored and placed for a long term; the clay coating can be thickened or thinned randomly so as to be beneficial to the perfect presentation of details of the work.

Description

technical field [0001] The invention relates to an art painting utensil, in particular to a universal smooth clay drawing board suitable for coloring with various pigments. Background technique [0002] Ordinary gypsum drawing boards will turn yellow, become brittle, and crack after being left for a long time, which will affect the preservation and collection of art works. Clay coating can completely solve the above problems, and it has oxidation resistance, so that the coating will not crack. During the Renaissance, this clay coating was used as a special coating for centuries-old murals in churches, making it still colorful and well preserved after thousands of years of light and air oxidation. The coating has a museum quality, but the technique has long been lost. Contents of the invention [0003] Aiming at the above-mentioned defects existing in the prior art, the purpose of the present invention is to provide a kind of all-purpose wrinkled surface clay drawing board...
