The invention has the beneficial effects that:
1. the self-cleaning glass hydrophobic agent provided by the invention can form a transparent hydrophobic film on the surface of automobile glass, water drops can form water drops on the surface of the glass, the contact angle can reach up to 125 degrees, automatic rolling-off can be realized without leaving traces, and the problem of unclear sight is solved.
2. The self-cleaning glass hydrophobic agent disclosed by the invention has better hydrophobicity and weather resistance, is effective for a long time after being used, has the advantages of wear resistance, washing resistance and the like, and keeps the attractiveness of glass without influencing the transmittance of the glass.
3. After the component A is sprayed on the surface of the glass, the nano particles can fill up microscopic pores on the surface of the glass, and because the nano particles have high specific surface area and act on the surface of the glass together with the terpolymer, the terpolymer forms a strong bonding effect with the nano particles and the surface of the glass, so that the surface of the glass has a layer of long-term effective, wear-resistant and washing-resistant reference film.
4. The component B forms a transparent hydrophobic film after being used, the nano titanium oxide in the hydrophobic film has a photocatalytic effect, and can decompose organic pollutants attached to the hydrophobic film under the irradiation of sunlight, so that the cleaning performance is obtained, the attachment amount of the organic pollutants is small, and C-F bonds in organic fluorides have high stability and slow decomposition speed, so that the hydrophobic film can keep the hydrophobic effect for a long time, and when the rainy day comes, rainwater can quickly take away inorganic matters on the surface of the hydrophobic film, so that the glass is bright as new.
5. The component B can be used after being diluted by 30-50 times by water as a cleaning agent, because the copolymer exists in the component B, when the component B is cleaned, the water can take away the dust on the surface of the hydrophobic membrane, and when the solvent damages the surface of the hydrophobic membrane, the copolymer, titanium oxide and other substances in the component B can be attached to the surface of the original hydrophobic membrane, and a new hydrophobic layer can be formed on the surface of the hydrophobic membrane after the solvent is volatilized, so that the service life of the hydrophobic membrane is prolonged, and the self-cleaning effect is improved.
