Method for preparing high-hardness antifouling paint with excellent self-cleaning and insulating performances

Abstract

The invention discloses a method for preparing high-hardness antifouling paint with excellent self-cleaning and insulating performances. After cetyl dimethyl benzyl ammonium chloride intercalated modification, montmorillonite reaches nanoscale size and is an ideal material for constructing a super-hydrophobic surface of a micro-nano sheet layer. A silane coupling agent is adopted for modifying perfluoropolyether acyl fluoride to prepare perfluoropolyether siloxane, and using the perfluoropolyether siloxane for modifying montmorillonoid and nano silicon dioxide realizes a surface energy reducing effect; under the action of the silane coupling agent, silver ions are loaded into polyaniline nano fibers with excellent in corrosion resistance, and excellent anticorrosion and antibacterial performances in paint are achieved; by doped silicon dioxide particles and nano montmorillonoid for modifying a micro structure on the low-surface-energy resin surface, a prepared coating has super-hydrophobic, self-cleaning and high-hardness performances. The method for preparing the antifouling paint is simple, low in cost, suitable for large-scale popularization and promising in application prospect.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a preparation method of an antifouling coating with high hardness, high self-cleaning and excellent insulation performance. Background technique [0002] Power and electrical equipment and devices operating outdoors are prone to dirt on the surface under the action of an electric field or natural conditions, which not only affects the appearance and efficiency of power equipment, but also when encountering harsh conditions such as rain, fog, dew, snow, ice, etc. It will also lead to the increase of conductance, the decline of insulation performance, and the occurrence of leakage, pollution flashover, flashover and other phenomena. Pollution flashover accidents involve a wide range, and the power outage lasts for a long time, which seriously threatens the safe operation of power transmission and transformation equipment and brings great economic losses to the national economy.

Problems solved by technology

Generally, perfluoroalkane resins have poor solubility and need to be heated and melted before use

After hybridization with other organic polymers, although the problems of solubility and room temperature curing are solved, the introduction of polyurethane, isocyanate resin and other polar components will greatly affect the low surface energy characteristics and aging resistance of the material
