Description
Technical Field
The invention relates to the technical field of paint preparation, and particularly relates to a preparation method of phenyl polysiloxane super-hydrophobic paint.
Background
In recent years, due to the special wettability and potential application value of the surface of the super-hydrophobic coating, the super-hydrophobic coating attracts wide attention in the industry. However, the raw materials for preparing the super-hydrophobic coating are basically fluorine-containing compounds or organosilane with complex structure and high price, and special equipment, harsh environment and other conditions are needed for preparing the coating. In addition, the mechanical strength and durability of the surface of the prepared super-hydrophobic coating can not meet the requirements of practical application. The above factors limit the application of superhydrophobic coatings in the fields of self-cleaning, corrosion prevention, drag reduction, and the like.
Disclosure of Invention
The purpose of the invention is as follows: aiming at the problems in the prior art, the invention provides a preparation method of phenyl polysiloxane super-hydrophobic coating, and the prepared phenyl polysiloxane super-hydrophobic coating has the advantages of good wear resistance, high usable temperature and the like.
The technical scheme is as follows: the invention provides a phenyl organopolysiloxane super-hydrophobic coating,
at room temperature, adding a certain proportion of diphenyl dihydroxy silane solid precursor and a photobase generator into a certain amount of organic solvent, mixing and stirring uniformly, and spraying and coating on a substrate; and (3) after the substrate coated with the sample is illuminated under an ultraviolet lamp for a preset time, putting the substrate into an oven for drying to obtain the phenyl polysiloxane super-hydrophobic coating.
Preferably, the mass ratio of the diphenyl dihydroxysilane solid precursor to the photobase generator is 1: 0.02-0.10.
Preferably, the photobase generator is 2-methyl-1- (4-methylthiophenyl) -2-morpholinyl-1-propanone, 2-phenylbenzyl-2-dimethylamine-1- (4-morpholinylbenzyl) butanone or 2- (4-methylbenzyl) -2- (dimethylamino) -1- (4-morpholinylphenyl) -1-butanone.
Preferably, the organic solvent is ethanol, tetrahydrofuran, toluene, chloroform or acetonitrile.
Preferably, the preset time is 20-60 min. Preferably, the temperature of the oven is 60-120 deg.CoC. Preferably 80 to 100oC。
Preferably, the drying time is 24-288 h. Preferably, the drying time is 48-144 h.
Preferably, the power of the ultraviolet lamp is 0.1-20 mW/cm2Preferably 0.5-5 mW/cm2。
Preferably, the wavelength of the ultraviolet lamp is 240nm or 320 nm.
Preferably, the substrate is glass, filter paper, silicon wafer, aluminum alloy, tinplate or polycarbonate.
Has the advantages that: in the invention, diphenyl dihydroxy silane and a photobase generator are added into a small amount of organic solvent, and after being mixed and stirred uniformly, the mixture is sprayed on a substrate to obtain a liquid coating; and then placing the mixture under an ultraviolet lamp for illumination for 20-60min to generate organic quaternary ammonium base to initiate the condensation polymerization of SiOH groups in the silane precursor, wherein the diphenyl polysiloxane has super-hydrophobic performance due to the hydrophobic characteristic provided by phenyl functional groups in the silane and the combination of the rough structure on the surface of the coating. Based on the mechanism of silicon hydroxyl condensation polymerization reaction, different from the traditional siloxane condensation catalyzed by acid, the condensation reaction of siloxane catalyzed by alkali can lead the coating to obtain higher polymerization degree (condensation degree), thereby further improving the mechanical strength and hydrophobic property (reduction of Si-OH groups) of the coating.
The invention introduces the photobase generator, generates base through illumination to catalyze the polycondensation reaction of the silane precursor, and compared with the traditional scheme of directly adding the base catalyst, the solution of the formula is very stable in the environment without ultraviolet light; can be sealed and placed for more than 1 year. Meanwhile, in the super-hydrophobic coating, the polysiloxane main chain has high mechanical strength and good wear resistance, and phenyl polysiloxane is easy to self-assemble and crystallize by combining the pi-pi conjugation effect among benzene ring groups, so that the super-hydrophobic performance of the coating has good thermal stability, the situations of poor wear resistance, short service time and poor use effect of the existing super-hydrophobic coating are effectively overcome, and the preparation method is simple to operate.
