Problems solved by technology

[0003] The photodegradation method of traditional self-cleaning materials is only suitable for sunlight environment, short coating, low dust removal efficiency, high cost, low efficiency, poor stability, secondary pollution and other problems
Traditional self-cleaning coatings can no longer meet the current use requirements in terms of life, dust removal efficiency, stability, and environmental protection rate, so new self-cleaning materials must be explored

preparation example Construction

[0020] The preparation method of the hydrophobic and oleophobic self-cleaning coating of the embodiment of the present invention may include the following steps, for example: mixing fluorine-containing olefin monomers, nanoparticles and inducers; the inducers include (NH 4 ) 2 S 2 o 8 .

[0021] Fluorocarbon polymers not only have excellent durability and chemical stability and excellent surface properties, but also exhibit excellent hydrophobic and oleophobic properties. The fluorine-containing olefin monomer is used as one of the raw materials in the embodiment of the present invention. The reason is that compared with hydrogen atoms, fluorine atoms are easier to shield the C-F structure, which can effectively protect the carbon atoms and carbon chains in the matrix material, and the carbon The longer the chain, the more fluorine atoms there are, and the more hydrophobic the material.

[0022] As an option, the types of fluorine-containing olefin monomers in the embodime...

[0035] Tridecafluorooctyl methacrylate and dodecafluoroheptyl acrylate were uniformly mixed in a polymerization vessel at a volume ratio of 1:1.5 at a speed of 300 r / min.

[0036] Add nano-core-shell structure SiO to the well-mixed olefin monomer 2 Granules, mix evenly at the same speed.

[0037] At a speed of 450r / min, add (NH 4 ) 2 S 2 o 8 Induces polymerization of olefin monomers. After reacting for 30 minutes, cool naturally to obtain a hydrophobic and oleophobic self-cleaning coating.

Embodiment 2

[0039] Tridecafluorooctyl methacrylate and dodecafluoroheptyl acrylate were uniformly mixed in a polymerization vessel at a volume ratio of 1:1 at a rotational speed of 250 r / min.

Abstract

The invention relates to hydrophobic and oleophobic self-cleaning coating, a preparation method and application of the hydrophobic and oleophobic self-cleaning coating and solar equipment, and belongsto the field of new generation of self-cleaning coating. The preparation method of the coating comprises the step of mixing fluorine-containing olefin monomers, nanoparticles and an inducing agent, wherein the inducing agent is prepared from (NH4)2S2O8. The working procedures of the preparation method are simple; the condition controllability is high. The obtained hydrophobic and oleophobic self-cleaning coating overcomes the defects of the traditional self-cleaning coating in aspects of service life, dust removal rate, stability, environment protection rate and the like; good characteristicssuch as better ultraviolet resistance, high luster, high combining powder, impact resistance and bending resistance are fully shown. When the coating is applied to the preparation of the solar equipment, the manual cleaning cost can be properly reduced, and the energy storage efficiency is improved. The solar equipment coated with the self cleaning coating has the higher energy storage efficiency.

Description

technical field [0001] The invention relates to the field of a new generation of self-cleaning paint, and in particular to a hydrophobic and oil-repellent self-cleaning paint, its preparation method and application, and solar energy equipment. Background technique [0002] With the development of semiconductor, photovoltaic and other technologies, my country's solar energy development and utilization technology has made great progress, and the matching development of solar energy development and utilization technology is the basic technology to support efficient energy storage of solar panels. For a long time, the adhesion of dust and oil stains on solar panels has become a bottleneck restricting the high-efficiency operation of solar energy efficient utilization equipment. Therefore, the development of self-cleaning materials and technologies suitable for dusty and oily environments is of great significance for improving the energy storage efficiency of solar energy efficie...
