Abstract

The invention discloses environment-friendly aqueous road paint and manufacturing method thereof. Components such as water, a dispersing agent, inorganic salt fillers, diatomite, a wetting agent, rutile type titanium white powder, photocatalyst, acrylic emulsion, a pH regulating agent, a defoaming agent, a thickening agent, a film forming aid, and the like are sufficiently mixed according to a certain process flow. By utilizing the strong adsorptive capacity of the diatomite, harmful substances in vehicle exhausts are absorbed in a coating containing the photocatalyst, and the photocatalyst absorbs optical energy amount to below bandgap energy under the irradiation of light so as to ensure that electrons of the photocatalyst obtain certain energy to separate from the constraints of atomic nucleuses and electron orbits and become free electrons, thus various harmful gases in the vehicle exhausts, such as carbon monoxide, hydrocarbons, nitric oxides and the like can be oxidized and decomposed to finally form carbon dioxide, water and other innocuous substances having no harm to the human body so as to achieve the purpose of degrading the vehicle exhausts, thereby reducing photochemical smog phenomena.

Description

technical field [0001] The invention relates to a decorative and protective paint for urban road surfaces and a manufacturing method thereof, in particular to an environment-friendly water-based road paint and a manufacturing method thereof. Background technique [0002] With the continuous development of society and the continuous progress of human civilization, the earth's environment is gradually deteriorating. More and more air pollutants are directly or indirectly discharged into the atmosphere. When these pollutants reach a certain concentration, there will be Lead to photochemical and other pollution problems, thereby endangering human health. Automobile exhaust is one of the most important sources of pollution. There are three main pollutants: carbon monoxide (CO), hydrocarbons (HC) and nitrogen oxides (NO). X ). [0003] Among them, the affinity between carbon monoxide and heme is 210 times greater than that between oxygen and heme. Therefore, when carbon monoxide...
