Abstract

The invention provides a bio-based composite dust suppressant, which comprises the following components in mass percent: cardanol polyoxyethylene ether 10% to 30%, cardanol sulfonate 10% to 30%, calcium magnesium lactate 1 %~5%, diatomaceous earth / sodium carboxymethylcellulose compound 0.5%~1%, glycerin 0.5%~3%, the balance is deionized water; the preparation method is: (1) Divide deionized water into A , two parts of B; (2) add cardanol polyoxyethylene ether, cardanol sulfonate, calcium magnesium lactate and glycerin in the stirring tank 1 that A part deionized water is housed, stir until completely dissolved, obtain mixture a (3) add diatomaceous earth / sodium carboxymethyl cellulose compound in the mixing tank 2 that B part deionized water is housed, at 50 ℃, stir, stand still, obtain mixture b; (4) mix mixture b and mixture a are stirred and mixed evenly to obtain a bio-based composite dust suppressant. The dust suppressant provided by the invention has good biodegradability, does not pollute the water and soil environment again, and has a dust suppression efficiency as high as over 90%.

Description

technical field [0001] The invention belongs to the technical field of environmental pollution control, and in particular relates to a bio-based composite dust suppressant and a preparation method thereof. Background technique [0002] In recent years, in the process of "resolutely defending the blue sky", the technology of dust suppressant to control dust concentration has been widely adopted; people have begun to use road dust suppressant to control inhalable particulate matter, reduce the concentration of inhalable particulate matter, Improve air quality. However, with the widespread application of dust suppressant technology, the ecological environment has more stringent requirements for dust suppressants - green and environmentally friendly. [0003] At present, it is more common to use alkylphenol polyoxyethylene ether as surfactant in the preparation of dust suppressant; for example, nonylphenol polyoxyethylene ether is widely used as wetting agent in the formula of ...
