Embodiment 1
[0027] The steps of the preparation method of the dust suppressant with photocatalytic activity of the present embodiment are as follows:
[0028] ①. Stir a sufficient amount of anatase-type nano-titanium dioxide powder with water, after ultrasonic treatment, let it stand still, take the supernatant, and irradiate it with visible light in a dark room. If a bright path is found, it proves that the supernatant is colloid, and titanium dioxide is selected The particle size is 1-100nm, and a styrene-acrylic emulsion with a concentration of 1% is added to prepare Sol A;
[0029] 2. Fully mix 0.3:0.2 parts by weight of calcium acetate and magnesium acetate with 30 parts by weight of water to make an aqueous solution of calcium-magnesium acetate salt;
[0030] ③. Add 0.04 parts by weight of sodium dodecylbenzenesulfonate to the calcium magnesium acetate aqueous solution in step ② to prepare solution B.
Embodiment 2
[0032] The steps of the preparation method of the dust suppressant with photocatalytic activity of the present embodiment are as follows:
[0033] ①. Stir a sufficient amount of anatase-type nano-titanium dioxide powder with water, after ultrasonic treatment, let it stand still, take the supernatant, and irradiate it with visible light in a dark room. If a bright path is found, it proves that the supernatant is colloid, and titanium dioxide is selected The particle size is 1-100nm, and a styrene-acrylic emulsion with a concentration of 3% is added to prepare Sol A;
[0034] 2. Fully mix 0.6:0.1 parts by weight of calcium acetate and magnesium acetate with 30 parts by weight of water to make calcium magnesium acetate aqueous solution;
[0035] ③. Add 0.04 parts by weight of sodium dodecylbenzenesulfonate to the calcium magnesium acetate aqueous solution in step ② to prepare solution B.
