Abstract

The invention discloses a preparation technology of a UV-resistant hydrophobic material. Perfluorooctyl acrylate, acrylic acid and hydroxyethyl acrylate serve as raw materials, azodiisobutyronitrile serves as an initiator, and a perfluorooctyl acrylate homopolymer is prepared through reasonable reaction temperature setting and a dripping technology; the perfluorooctyl acrylate homopolymer, isocyanate, a silane coupling agent and trifluoroethanol are mixed in proportion to prepare a UV-resistant hydrophobic film liquid. The UV-resistant hydrophobic film liquid is used for being sprayed on the surface of a glass base material or a ceramic base material and has the characteristic of normal-temperature curing or low-temperature curing, and a formed film layer has good UV resistance and ageingresistance and has good adhesive force on the glass base material and the ceramic base material.

Description

technical field [0001] The invention relates to a preparation process of a UV-resistant hydrophobic material, and belongs to the technical field of hydrophobic coating substrates. Background technique [0002] The function of the anti-fouling and anti-fingerprint film layer is to reduce the surface energy of the object surface (such as the surface energy of glass or metal) to form a film layer with super-hydrophobic properties. There are two ways to change the surface energy of an object. One is the physical surface roughness modification method: according to the self-cleaning theory, the rougher the surface structure, the better the hydrophobic self-cleaning effect can be produced, but the rough surface can cause serious scattering of visible light , to make the coating appear opaque, and to reduce the mechanical properties, such as adhesion and anti-abrasion effects. This method is not suitable for the current protective glass industry; another method is to add fluorine fu...
