Abstract

The invention discloses photocatalytic nanometer spray coating and a method for preparing the same, and belongs to the technical field of photocatalytic coating. The photocatalytic nanometer spray coating comprises, by weight, 48.5%-49.5% of asphalt, 50%-51% of liquid soap and 0.5%-1% of silane coupling agents. The sum of the mass percents of the asphalt, the liquid soap and the silane coupling agents is a hundred percent; the liquid soap comprises, by weight, 0.4%-2% of stabilizers, 3%-6% of emulsifiers, 2%-6% of dispersing agents, 10%-20% of nanometer TiO2 and the balance high-purity water, and the sum of the mass percents of various components of the liquid soap is a hundred percent; the mass of the dispersing agents accounts for 20%-30% of that of the nanometer TiO2. The photocatalytic nanometer spray coating and the method have the advantage that problems that road spray coating is poor in storage stability, colors of the road spray coating are greatly different from colors of asphalt pavements, the antislip and permeability performance of the pavements are deteriorated and the driving safety is affected in the prior art can be solved by the aid of the photocatalytic nanometer spray coating and the method.

Description

technical field [0001] The invention belongs to the technical field of photocatalytic coatings, and relates to a photocatalytic nano-spray coating used for degrading automobile exhaust in roads and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of my country's automobile industry, automobiles have entered thousands of households. While automobiles bring convenience to people, automobile exhaust emissions from automobiles have also brought more and more serious air pollution. At the time, the self-purification ability of the atmosphere could purify most of the automobile exhaust, but now the number of automobiles is increasing rapidly, and the exhaust gas emitted by the automobile far exceeds the self-purification ability of the atmosphere. According to statistics, every 1,000 vehicles in the city emit about 3000kg of CO, about 200kg to 400kg of HC, and about 200kg to 400kg of NO. x About 50kg to 150kg. By the end of 20...
