Description

technical field [0001] The invention belongs to the technical field of polymer materials, and particularly relates to an antistatic optical-grade hydrophobic material and a preparation method thereof. Background technique [0002] Static dissipative materials refer to materials with a surface resistivity of 106 to 1012 ohms, of which materials with a surface resistivity of 1010 to 1012 ohms have the effect of preventing the local accumulation of static electricity and can effectively avoid electrostatic dust collection; the surface resistivity is The material of 106-109 ohms has the effect of rapidly dissipating static electricity, which can effectively prevent potential safety hazards such as electric shock and fire caused by electrostatic discharge. In the fields of optics and electronic / electrical appliance manufacturing, the antistatic properties of antistatic materials are often produced by the action of macromolecular antistatic agents. Due to their high surface area r...

However, the internal components of its antistatic material are poorly formed, resulting in poor consistency of the product as a whole

[0003] The wettability of the material surface is a complex property. Generally, the contact angle greater than 90 degrees is hydrophobic, and greater than 150 degrees is superhydrophobic. When the material has functional requirements such as antifouling and self-cleaning, a corresponding hydrophobic layer will be used. In the prior art, hydrophobic coatings are usually compounded on the base layer. Although it is simple, convenient and easy to implement, it is easily scratched and washed off after being affected by adverse factors such as external high temperature and impact for a long time. Shedding failure, as disclosed in Patent No. CN107022279B "A Preparation Method for Highly Transparent Wear-Resistant Super-hydrophobic Composite Coating", scrape-coat modified epoxy resin glue on the surface of the substrate as a bonding layer, and then brush the surface hydrophobic Nano-silica dispersion, dry at room temperature, to obtain a highly transparent and wear-resistant epoxy resin / silica super-hydrophobic composite coating, brushed nano-silica dispersion will peel off in a bad environment for a long time, and at the same time Substrate separation
