Embodiment 1
[0022] A polymer-based dust control product is made from the raw materials shown in Table 1.
[0023]
Embodiment 1~9
[0024] Embodiment 1~9 preparation method, the steps are as follows:
[0025] (1) According to the raw material composition described in Table 1, polyacrylamide, polyvinylpyrrolidone, polyethylene oxide-polypropylene oxide-polyethylene oxide triblock copolymer, polyvinyl alcohol, polyethylene glycol Alcohol, polymaleic anhydride, polyacrylic acid, trisodium phosphate, sodium chloride and pigments were placed in a reaction vessel, stirred at a low speed of 80 rpm for 4 h, then left to react for 12 h, and then transferred to a high-speed shearing machine at 1000 rpm Shear for 3 h, then cool down to room temperature naturally after shearing;
[0026] (2) Transfer the powder obtained after shearing in step (1) to an electric blast drying oven at 90 °C for 15 h, and pass through a 300-mesh sieve to obtain a polymer-based dust control product.
Embodiment 8
[0027] The digital photograph of embodiment 8 products sees figure 1 ,From figure 1 It can be clearly seen that the product of the present invention is a small granular powder with uniform particle size.
[0028] Dustproof effect test
[0029] The products prepared in Examples 1-9 were tested for dustproof effect. The method is as follows: first, take 1000 g of loess and dry it in an electric blast drying oven at 80 °C for 15 h, then take out the dried loess, crush the loess with a pulverizer for 3 h, and spread the crushed loess evenly to 2 m 2 In the tray, take 5 g of the product prepared in Examples 1 to 9 and add 500 g of water to dilute and dissolve it, then spray it into the above tray, then put the tray into a drying and heat preservation room at 50 ° C for 72 h, and finally the tray The loess in the soil was placed in a simulated natural wind with a wind speed of level 7 for a blowing experiment, and the mass of the tray was weighed after blowing for 2 hours. If th...
