Problems solved by technology

However, these methods involve complex chemical substances and crystal growth, the implementation conditions are relatively harsh, the production cycle is long, and the cost is high, so it cannot be industrialized.
[0003] At present, the most successful commercial applications in the field of material surface hydrophobicity are superhydrophobic coatings and microporous films. Poor strength, easy to fall off during use; and microporous film due to its poor physical and mechanical properties, coupled with the stability of its adhesion to the surface of polar materials, the service life is also limited

Abstract

The invention relates to the field of paint, particularly to hydrophobic UV (ultraviolet) curing paint. The hydrophobic UV curing paint comprises the components in percentage by weight as follows: 20%-60% of silane modified resin, 15%-40% of monomers, 2%-4% of a photoinitiator, 20%-50% of a diluent and 0.5%-2% of a functional additive; the silane modified resin comprises the components in percentage by weight as follows: 40%-60% of bisphenol A epoxy acrylate, 35%-55% of bi-functional polyester acrylate and 1%-7% of a silane coupling agent. According to the hydrophobic UV curing paint, the silane modified resin is adopted, so that a paint film can have a hydrophobic property; the monomers with single functional groups are adopted, so that the compatibility of the resin and the monomers can be further improved, and the whole paint film has better iquidity, flexibility and adhesive force.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a hydrophobic ultraviolet light curing paint. Background technique [0002] Due to the unique surface properties of hydrophobic and superhydrophobic surfaces, they have potential applications in self-cleaning surfaces, microfluidic systems, and biocompatibility, and have broad application prospects in national defense, daily life, and many industrial fields. become a research hotspot. It is recognized that the hydrophobic properties of hydrophobic and superhydrophobic surfaces are controlled by the chemical composition and structure of the material surface. At present, there are many studies on the hydrophobicity of the surface of solid materials. The commonly used methods include surface grafting, etching, sol-gel method, electrospinning method, chemical vapor deposition method, anodic oxidation method, phase separation method and template method. However, these methods involve complex...
