Abstract

The invention relates to the technical field of dust depressor processing and discloses a preparation method of a dust depressor with a catalysis function. The method comprises the steps as follows: (1) dissolving a film forming substrate in water under the heating condition of 40-70 DEG C, adding a crosslinking agent after complete dissolution, and conducting a crosslinking reaction under the heating condition of 62-85 DEG C; (2) after the crosslinking reaction in step (1) is finished and a mixed solution is cooled to the room temperature, firstly, adding a nonionic surfactant, a dispersant and a defoaming agent to the mixed solution to be stirred, slowly adding a photocatalyst, and fully and uniformly stirring the mixture to obtain a finished product, namely, the dust depressor. The prepared dust depressor can effectively depress flying of rising dust on road surfaces and fix PM2.5 and NOx to a great extent and is long in service life and convenient to use.

Description

technical field [0001] The invention relates to the technical field of dust suppressant processing, in particular to a method for preparing a dust suppressant with catalytic function. Background technique [0002] In recent years, the problem of regional air pollution in my country, characterized by inhalable particulate matter (PM10) and fine particulate matter (PM2.5), has become increasingly prominent. Serious air pollution has threatened the physical and mental health of people in relevant regions, so it is urgent to control this kind of air pollution. [0003] Studies have shown that in large urban environments, motor vehicle and traffic pollution is one of the contributing factors to air pollution, especially PM2.5 pollution. In addition to direct emissions, nitrogen oxides (NO x ) and coal-fired (SO 2 ) and the secondary aerosols produced by the photochemical reaction of hydrocarbons emitted from motor vehicle exhaust are also important contributors to environmenta...
