Abstract

The invention discloses an integral phenolic resin superamphiphobic anti-ultraviolet ageing coating and a preparation method thereof. The preparation method comprises the steps that a phenolic resin material reacts with anti-ultraviolet ageing particles (titanium dioxide) in a scarfing mode, so that an superamphiphobic micro-nano structure with a high-hardness characteristic is formed; phenolic resin emulsion is scarfed through the particles by means of the shearing dispersion and in-situ filling technologies; and thus, a modified particle disordered stacking superamphiphobic structure is formed. The anti-ageing performance of the coating is remarkably improved, the coating is made to have the anti-ultraviolet characteristic under the photocatalysis effect of the particles, the coating is integrally prepared, and theory subverting and technical breakthrough in the preparation process of the phenolic resin superamphiphobic coating are achieved.

Description

technical field [0001] The invention relates to the field of super-amphiphobic composite coatings, in particular to a phenolic resin integrated super-amphiphobic anti-ultraviolet aging coating and a preparation method thereof. Background technique [0002] As early as the 1970s, Barthlott, a European botanical taxonomy scientist, proposed the concept of "lotus leaf effect". Roll freely on the top, take away the dust and sludge on the leaf surface, and keep the leaf surface clean and clean all the time. [0003] After decades of development, the research on super-hydrophobic and super-amphiphobic coatings has made rapid progress, but at present, super-amphiphobic coatings still face the following technical bottlenecks: [0004] (1) The bonding fastness between the microscopic rough structure and the substrate, and between the microscopic rough structures is not enough, the rough structure is easily damaged, the strength is weak, and it is easy to suffer from abrasion, making...
