Abstract

The rainproof and dust suppression agent provided by the invention comprises the following raw materials: water-soluble polymer; organic bentonite; water-soluble starch; moisturizing agent; surface active agent; binder and water. Among them, the water-soluble polymer is used as the skeleton material, which can be closely combined with other components through interactions such as hydrogen bonds to form a stable composite structure; the surfactant is conducive to the infiltration of dust, and has the same properties as the water-soluble polymer. Good compatibility and binding ability; the humectant and the binder work together to retain water, resist evaporation, and resist wind erosion; organic bentonite and water-soluble starch combine with each other to increase the firmness of the film through π‑π electron interaction , and cooperate with other components to improve the film-forming properties of the dust suppressant and the performance of anti-rain erosion and anti-cracking; the rain-proof and dust-suppressant can not only prevent rain erosion and cracking through the synergistic effect of various components, but also have Excellent adhesion and fast film-forming properties, increase the surface strength and quickly form a film on the surface.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a rain-proof and dust-suppressant agent and a preparation method thereof. Background technique [0002] With the continuous acceleration of my country's industrialization and the continuous expansion of cities, the environmental pollution problems caused by coal yard stacking, coal burning, mineral processing, construction and motor vehicle exhaust are becoming more and more serious. Among them, dust pollution is a particularly serious type of environmental pollution, and it is also the most important cause of frequent haze weather. Flying dust floats in the air and is easily absorbed by the human body, directly endangering human health. Therefore, the dust pollution control project is imperative and the task is urgent. [0003] In recent years, starting from the characteristics of dust and the mechanism of dust emission, chemical dust suppressants have fundamen...
