Embodiment 1

[0019] A composition for adjusting the color of concrete, comprising an emulsion mixture and a color paste subpackaged therewith. The emulsion mixture consists of: 28% pure acrylic emulsion (here adopts the pure acrylic emulsion 2900 manufactured by American National Starch Chemical Co., Ltd., which is an acrylic ester copolymer emulsion), 8% water, and 0.4% dispersant (here adopts the Japanese Nopco company to produce SN-5040, which is polycarboxylate sodium salt), industrial propylene glycol 2.5%, preservative 0.15% (here adopts the high-efficiency tank preservative LXE produced by Rohm and Haas Company of the United States), rutile titanium dioxide 8% (here adopts R-902 produced by U.S. DuPont Company), 35% of 400 mesh heavy calcium carbonate, 13% of 325 mesh quartz sand, 2.5% of alcohol ester twelve film-forming aids, 0.25% of thickener (adopted here by Japanese Nopco Co., Ltd. The SN-612 produced is a polyurethane associative thickener), 2% of a hydrophobic agent (BS1306 ...

Embodiment 2

[0023] A composition for adjusting the color of concrete, comprising an emulsion mixture and a color paste subpackaged therewith. The emulsion mixture is composed of: pure acrylic emulsion 2900 30%, water 10%, SN-5040 dispersant 0.4%, industrial propylene glycol 3.0%, LXE preservative 0.20%, R-902 titanium dioxide 12%, 400 mesh ground calcium carbonate 30 %, 325 mesh quartz sand 10%, alcohol ester twelve film-forming aids 3.0%, BS1306 hydrophobic agent 1.0%, SN-612 thickener 0.3%, and AMP-95 PH value regulator 0.1%. The quality of red color paste C27, yellow color paste C16 and black color paste C8 is 0.02% of the mass of the emulsion mixture.

[0024] According to the color of the concrete wall used in the test, color paste was added to the above emulsion mixture for deployment, and its performance was tested according to the "Synthetic Resin Emulsion Exterior Wall Coating" GB / T9755-2001 standard. The test results are shown in Table 2.

Embodiment 3

[0027] A composition for adjusting the color of concrete, comprising an emulsion mixture and a color paste subpackaged therewith. The emulsion mixture is composed of: pure acrylic emulsion 2900 32%, water 10%, SN-5040 dispersant 0.4%, industrial propylene glycol 2.5%, LXE preservative 0.20%, R-902 titanium dioxide 10%, 400 mesh ground calcium carbonate 28.5 %, 325 mesh quartz sand 12%, alcohol ester twelve film-forming aids 2.4%, BS1306 hydrophobic agent 1.5%, SN-612 thickener 0.3%, and AMP-95 PH value regulator 0.2%. The mass of red color paste C27, yellow color paste C16 and black color paste C8 is 0.03% of the mass of the emulsion mixture.

[0028] According to the color of the concrete wall used in the test, color paste was added to the above emulsion mixture for deployment, and its performance was tested according to the "Synthetic Resin Emulsion Exterior Wall Coating" GB / T9755-2001 standard. The test results are shown in Table 3.

Abstract

A composition for adjusting concrete pigment consists of pure propyl-emulsion 26-35 wt%, water 10-15 wt%, dispersant 0.3-0.4 wt%, anti-freezing agent 2-4 wt%, antiseptics 0.1-0.3 wt%, titanium pigment 8-10 wt%, filler 37-53 wt%, filming accessory 2-3 wt%, hydrophobic agent 2-5 wt%, thickener 0.2-0.5 wt% and pH regulator 0.1-0.3 wt%. The color paste comprises red, yellow and black three kinds, each kinds occupies 0.03-0.06 wt%. It has excellent weather resistance.

Description

technical field [0001] The invention relates to a material for adjusting the color of concrete, in particular to a composition for adjusting the color of concrete before transparent protection. Background technique [0002] Concrete transparent coating system is a form of architectural expression, first started in Japan, this form of architectural expression can completely and effectively retain the natural color and texture of the concrete building itself, the appearance is simple, it is a return to nature and return to nature Performance. Before the concrete is transparently painted, the defects of the concrete need to be repaired, and the color needs to be adjusted after the repair. After adjusting the color of concrete with conventional materials and then applying topcoat, the topcoat will turn black or lose the texture of concrete. There are also some concrete color adjustment materials, and the color of the wall begins to turn yellow, black and alkali soon after cons...
