Embodiment 1

[0043] This embodiment is an antibacterial monomer, and the preparation process of the antibacterial monomer is as follows:

[0044]S1: Add dimethylaminoethanol, methyl acrylate, polymerization inhibitor a and catalyst to a three-necked flask equipped with a thermometer, a magnetic stirrer, a condensing reflux tube and a fractionating column. The temperature of the reaction system is raised to boiling, the temperature is controlled at 85°C, the temperature at the top of the fractionation column is 63.5°C, and the reaction is refluxed for 5 hours at a reflux ratio of 4:1 until no fraction is discharged, and then the pressure is reduced to 0.05MPa, and the temperature at the top of the fractionation column is controlled. at 37°C, reflux under the condition of reflux ratio of 4:1 until no distillate is discharged, and then the pressure is reduced to 3.3×10 3 Pa, control the temperature at the top of the fractionation column to be 88°C, collect fractions to obtain intermediate pro...

Embodiment 2

[0047] This embodiment is an antibacterial monomer, and the preparation process of the antibacterial monomer is as follows:

[0048] S1: Add dimethylaminoethanol, methyl acrylate, polymerization inhibitor a and catalyst to a three-necked flask equipped with a thermometer, a magnetic stirrer, a condensing reflux tube and a fractionating column. The temperature of the reaction system is raised to boiling, the temperature is controlled at 100°C, the temperature at the top of the fractionating column is 66°C, and the reaction is refluxed for 5.5 hours under the condition of a reflux ratio of 4:1, until no fraction is discharged, and then the pressure is reduced to 0.05MPa, and the top of the fractionating column is controlled to The temperature was 41°C, refluxed under the condition of reflux ratio 4:1 until no distillate was discharged, and then the pressure was reduced to 3.3×10 3 Pa, control the temperature at the top of the fractionation column to be 89°C, collect fractions to...

Embodiment 3

[0051] This embodiment is an antibacterial monomer, and the preparation process of the antibacterial monomer is as follows:

[0052] S1: Add dimethylaminoethanol, methyl acrylate, polymerization inhibitor a and catalyst to a three-necked flask equipped with a thermometer, a magnetic stirrer, a condensing reflux tube and a fractionating column. The temperature of the reaction system is raised to boiling, the temperature is controlled at 115°C, the temperature at the top of the fractionation column is 70°C, and the reaction is refluxed for 6 hours at a reflux ratio of 4:1 until no fraction is discharged, and then the pressure is reduced to 0.05MPa, and the temperature at the top of the fractionation column is controlled. at 45°C, reflux under the condition of reflux ratio of 4:1 until no distillate is discharged, and then the pressure is reduced to 3.3×10 3 Pa, control the temperature at the top of the fractionation column to be 90°C, collect fractions to obtain intermediate pro...

Abstract

The invention discloses an environment-friendly self-cleaning coating for a shower room and a preparation method of the environment-friendly self-cleaning coating, and relates to the field of self-cleaning coatings. The self-cleaning coating has good film-forming property and can be cured to form a film on a substrate to form the self-cleaning coating, and a large number of C-F bonds existing on dodecafluoroheptyl methacrylate are utilized. The introduced fluorine atoms are small in radius, strong in electronegativity and high in C-F bond energy, have the minimum Van der Waals radius besides hydrogen, and also have a shielding protection effect on carbon chains, so that the self-cleaning coating can be endowed with excellent low surface energy, water resistance, oil resistance, lubricity, heat resistance, chemical resistance and stain resistance, and therefore, the self-cleaning coating has a good self-cleaning function and is convenient to clean after being used in the shower room, meanwhile, the self-cleaning coating can be endowed with good antibacterial property by utilizing quaternary ammonium salt groups in the antibacterial monomers, bacterium breeding in the shower room is avoided, and the probability that people get ill is reduced.

Description

technical field [0001] The invention relates to the field of self-cleaning coatings, in particular to an environment-friendly self-cleaning coating for a shower room and a preparation method thereof. Background technique [0002] Self-cleaning coatings are divided into hydrophobic type and hydrophilic type according to the principle of achieving "self-cleaning" effect. The surface of the hydrophobic coating is super-hydrophobic. When water falls on the surface, the contact angle of the water drop is greater than 110 degrees, so that the water is in the form of water droplets on the surface of the coating. If the surface of the coating is inclined or vertical, the water droplets will roll off immediately. Does not stick to water, dust and stains roll off with water droplets. The surface of the hydrophilic coating is super-hydrophilic. When water falls on the surface, the contact angle of the water drop is less than 10 degrees, and then the water expands on the surface due to...
