Gypsum coating propylene pigment drawing board
Technical field
The present invention relates to a kind of art painting material, be specifically related to a kind of gypsum coating propylene pigment drawing board.
Background technology
Existing gouache is generally with gouache paper, has common gouache paper and the gouache paper of frosted finish effect; Common gouache paper and the gouache paper of frosted finish effect thicker, there is texture, there is certain water-absorbent, but can be wrinkling or roll when moisture is more or pigment is thicker, and long-time placement can slightly be turned to be yellow, thus affect preservation and the reserve value of gouache, and its sand grains of sand gouache paper had easily peels off, and affects the stereoscopic sensation of gouache.
Summary of the invention
In view of the foregoing defects the prior art has, the object of the present invention is to provide a kind of gypsum coating propylene pigment drawing board.Pigment drawing board of the present invention is not easily wrinkling, and can not turn to be yellow, sand grains is incrust, and the shelf time is long.
The present invention takes following technical proposals:
Gypsum coating propylene pigment drawing board, its preparation technology is as follows:
(1) slurry is made: by deionized water 180 ~ 210 parts, defoamer 1.5 ~ 2.5 parts, propylene glycol 18 ~ 22 parts, dispersion agent 4.5 ~ 5.5 parts, titanium dioxide 190 ~ 220 parts, talcum powder 180 ~ 220 parts, pure-acrylic emulsion 340 ~ 360 parts, multifunctional assistant AMP-951 ~ 2.5 part, defoamer 1 ~ 3 part, film coalescence aid 9 ~ 11 parts, thickening material ASE-6045 ~ 55 part, thickening material TT9351.5 ~ 2.5 part, 200 order marble flour 90 ~ 120 parts uniform stirring mixing;
(2) showering: with the hardboard of gypsum quality for base material, by the showering of step (1) made propylene pigment slurry in this substrate surface, is placed in thermostatic constant wet chamber until complete drying, obtains gypsum coating propylene gouache board finished product.
Particularly,
The described leaching coating process of step (2) adopts curtain coater, and it drenches the pressing creation of curtain film by surge pump, and thickness is adjustable, and it is 60 ~ 80m/min that showering transfer rate controls.
Described showering coat-thickness is 2 ~ 2.5mm.
The present invention has following Advantageous Effects:
Pigment drawing board of the present invention is the hardboard on a kind of clay and gypsum quality top layer, be decorated with marmorean dust particale, more durable and omnipotent than traditional sand pastel paper, can powder enamel Wet-dry or for acrylic painting etc., its top layer is neutral, and be long placed in and do not crease easily and turn to be yellow, sand grains is incrust, shelf time is long, is particularly useful for museum's preservation works; In technique, innovation adopts coating techniques, and make drawing board surface tension even, paintings are placed for a long time and do not warp and fracture.
