Embodiment 1

[0013] (1) First turn on the mixer to run at low speed, gradually add 33kg of water, 0.35kg of dispersant, 0.2kg of defoamer, 8kg of light calcium carbonate, and 8kg of heavy calcium carbonate, gradually increase the speed to fully mix the materials, and the stirring speed reaches the peripheral speed of the dispersion disc 20m / s or more; (2) Add 13kg of titanium dioxide, 10kg of talc and 3kg of white carbon black, and mix and stir for 40 minutes after adding; (3) Add 10kg of polyvinyl alcohol and 21kg of acrylic emulsion, at this time the peripheral speed of the dispersion disc is controlled 8-10m / s, and the stirring time is 10 minutes; (4) Add 1.5kg of thickener, at this time, the peripheral speed of the dispersing disc is controlled at 10-12m / s, and the stirring time is 5 minutes.

Embodiment 2

[0015] (1) First turn on the mixer and run at low speed, gradually add 1kg of water, 10g of dispersant, 8g of defoamer, 270g of light calcium carbonate, and 270g of heavy calcium carbonate, gradually increase the speed to fully mix the materials, and the stirring speed reaches the peripheral speed of the dispersion disc 20m / s or more; (2) Add 390g of titanium dioxide, 310g of talc and 100g of white carbon black, and mix and stir for 40 minutes after adding; (3) Add 300g of polyvinyl alcohol and 610g of acrylic emulsion, and the peripheral speed of the dispersion disc is controlled at 8 -10m / s, the stirring time is 10 minutes; (4) Add 30g of thickener, at this time, the peripheral speed of the dispersion disc is controlled at 10-12m / s, and the stirring time is 5 minutes.

Abstract

The invention relates to a water absorbent canvas coating which is characterized in that the water absorbent canvas coating is manufactured by the following materials in percentage by weight: 30 to 33water, 18 to 23 polyacrylic emulsion, 8 to 13 polyvinyl alcohol, 12 to 15 titanium pigment, 10 to 12 talcum powder, 7 to 10 light calcium carbonate, 7 to 10 heavy calcium carbonate, 2 to 4 silica white, 0.3 to 0.4 dispersant, 0.2 to 0.3 anti-foaming agent, and 1 to 2 thickening agent; and the canvas provided with the coating is particularly applicable to acrylic painting, the coating which is identical with acrylic paints ensures that the paints is very firmly bound with the canvas, and the acrylic paints can be used for being adjusted to water color effect and poster color effect on the canvas according to the requirements, to ensure that the color tolerance of the acrylic paints is better and the expressive force is stronger.

Description

technical field [0001] The invention relates to a water-absorbing canvas coating, and also relates to a manufacturing method of the coating. Background technique [0002] The canvas used in traditional acrylic painting has a poor binding force between the acrylic paint and the canvas due to the problem of water absorption. Both tolerance and expressiveness are restricted. Therefore, in order to better highlight the tolerance and expressiveness of acrylic paint painting, a new canvas is needed to make acrylic paint on the canvas to reconcile the effect of watercolor and gouache according to the needs, and at the same time, it can strengthen the combination of acrylic paint and canvas. Contents of the invention [0003] The object of the present invention is to provide a water-absorbing canvas coating which can make the combination of acrylic paint and canvas more firm, and can make the acrylic paint have better latitude and stronger expressive force and a manufacturing met...
