[0022] Make 1kg of photocatalytic nano-spray coating, in which anatase nano-TiO 2 Content is 16% of soap liquid quality, specifically carries out according to the following steps:

[0023] Step 1, the preparation of soap liquid: add the stabilizer CaCl of soap liquid quality 0.4% to high-purity water 2 After heating and fully stirring to dissolve, add the slow-cracking emulsifier SY-CME of 4% soap liquid quality to dissolve in the solution, and then add the sodium polyacrylate dispersant of 3.2% soap liquid quality (the addition of sodium polyacrylate dispersant Anatase Nano TiO 2 20% of the mass), and fully stirred to dissolve, then slowly add the anatase nano-TiO with 16% of the mass of the soap solution 2 , stirred for 15 minutes, and kept at 70°C for later use;

[0024] Step 2, heat the asphalt to a fluid state, and keep it warm at 140°C for use;

[0025] Step 3, emulsification: first add 0.505kg of soap liquid into the emulsifier, then add 0.485kg of asphalt into the ...

Embodiment 2

[0027] Make 1kg of photocatalytic nano-spray coating, in which anatase nano-TiO 2 The content is 10% of the soap liquid quality, specifically according to the following steps:

[0028] Step 1, the preparation of soap liquid: add the stabilizer NH of soap liquid quality 2% to high-purity water 4 Cl, after heating and fully stirring and dissolving, add the slow-cracking emulsifier SY-CME of 3% soap liquid quality to dissolve in the solution, then add the sodium polyacrylate dispersant (sodium polyacrylate dispersant) of soap liquid quality 2% The amount added is anatase nano-TiO 2 20% of the mass), and fully stirred to dissolve, then slowly add 10% of the mass of soap liquid anatase nano-TiO 2 , stirred for 15 minutes, and kept at 65°C for later use;

[0029] Step 2, heat the asphalt to a fluid state, and keep it warm at 135°C for use;

[0030] Step 3, emulsification: first add 0.5kg of soap liquid into the emulsifier, then add 0.495kg of asphalt into the emulsifier, emulsif...

Embodiment 3

[0032] Make 1kg of photocatalytic nano-spray coating, in which anatase nano-TiO 2 The content is 20% of the soap liquid quality, specifically according to the following steps:

[0033] Step 1, preparation of soap solution: add oxalic acid stabilizer with 1% soap solution mass to high-purity water, after heating and fully stirring to dissolve, add slow-cracking emulsifier SY-CME with 6% soap solution mass to dissolve in the solution, and then Then add the sodium polyacrylate dispersant of soap liquid quality 6% (the add-on of sodium polyacrylate dispersant is anatase type nanometer TiO 2 30% of the mass), and fully stirred to dissolve, and then slowly added anatase nano-TiO with 20% of the mass of the soap solution 2 , stirred for 15 minutes, and kept at 68°C for later use;

[0034] Step 2, heat the asphalt to a fluid state, and keep it warm at 138°C for use;

[0035] Step 3, emulsification: first add 0.51kg of soap liquid into the emulsifier, then add 0.485kg of asphalt int...

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 on 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, the exhaust gas emitted by automobiles has also brought more and more serious air pollution. Although there are fewer vehicles At that 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 emission of automobile exhaust far exceeds the self-purification ability of the atmosphere. According to statistical data, every thousand vehicles in the city emit about 3000kg of CO, about 200kg-400kg of HC, and about 200kg of NO x About 50kg~150kg, as ...
