Embodiment 1

[0051] A kind of anti-rain erosion dust suppressant for building construction, it is processed by the raw material that comprises the dosage shown in Table 1: Vegetable glue, water-based polymer emulsion, polyvinyl alcohol, sodium silicate, surfactant isomeric tridecanol Polyoxyethylene ether, silicone oil emulsion, hygroscopic agent triethanolamine, humectant glycerol, preservative N-(5-fluoropyridine)-D-glucopyranosesamine and water.

[0052] A preparation method of a rain erosion-resistant dust suppressant for building construction is prepared through the following operations:

[0053] Divide the water into 4 parts, add 3 / 4 of water, vegetable gum, water-based polymer emulsion, surfactant, hygroscopic agent, humectant and preservative to the first reaction tank, at 45 ℃, 700r / min , and continued to stir for 13 minutes to obtain the first mixed solution;

[0054] Add the remaining 1 / 4 water into the second reaction tank, and add polyvinyl alcohol and sodium silicate to the ...

Embodiment 2-4

[0057] The preparation method of the rain erosion-resistant and dust-suppressant of Examples 2-4 is the same as that of Example 1, the difference is that the dosage of each raw material is different, as shown in Table 1 for details.

[0058] Each raw material type and dosage (g) of the anti-rain erosion dust suppressant of table 1 embodiment 1-4

[0059]

Embodiment 5-10

[0061] The preparation method of the rain erosion-resistant and dust-suppressant of Examples 5-10 is the same as that of Example 1, the difference being that the types of components of vegetable glue are different, as shown in Table 2 for details, and the types and dosages of all the other raw materials are the same as those of Example 2. same.

Abstract

The invention relates to the technical field of dust suppression in building construction, in particular to a rain-erosion-resistant dust suppressant for building construction as well as a preparation method and application of the rain-erosion-resistant dust suppressant. The rain-erosion-resistant dust suppressant for building construction is processed from the following raw materials in parts by weight: 6-12 parts of vegetable gum, 4-8 parts of a water-based polymer emulsion, 3-5 parts of polyvinyl alcohol, 2-4 parts of sodium silicate, 1-5 parts of a surfactant, 2-4 parts of a silicone oil emulsion, 1-4 parts of a moisture absorbent, 2-5 parts of a humectant, 0.1-0.5 part of a preservative and 60-70 parts of water. The dust suppressant is good in film forming effect and small in influence of interference factors such as wind power resistance, the wind erosion rate can be as low as 0.26%, and the dust suppression rate can be as high as 98.5%. The rain erosion resistance rate of one-time circulation can reach 98%, the rain erosion resistance rate after five-time circulation can still reach 85%, and the rain erosion resistance is excellent.

Description

technical field [0001] The present application relates to the technical field of dust suppression in building construction, in particular to a rain erosion-resistant dust suppressant for building construction and its preparation method and application. Background technique [0002] In recent years, smog and sandstorms have occurred frequently in many places in my country, which have brought great troubles to residents' normal travel, production and life. Studies have shown that air pollution is the main cause of smog and sandstorms, and about 33% of the contribution to air pollution comes from dust pollution. During the construction process, excavation and filling of earth and stone, open stacking of building materials, and temporary road transportation will all cause construction dust. Construction dust has many points and wide areas, and it is also repetitive and sudden, which is difficult to be effectively controlled, thus causing adverse effects on the environment. [...
