Problems solved by technology

However, the aforementioned methods such as plasma polymerization require special equipment, and it is difficult to handle large surfaces. The coating film formed by the sol-gel method has poor flexibility, and it is difficult to meet the requirements for mechanical properties and corrosion resistance.
At the same time, too high hydrophilicity makes the surface easy to attach condensed water film, causing osmotic corrosion

Abstract

A thermotropic super hydrophilic resin. A titanate structural unit is introduced into a structure of the resin; and the titanate and epoxy resin are grafted, evenly distributed in the resin, and solidified to form a Ti-O-Si nano-structure. The thermotropic super hydrophilic resin provided by the invention maintains good corrosion resistance and mechanical properties of the epoxy resin, and has similar surface characteristics as a traditional organic resin. When temperature rises, surface microstructure changes due to stretching of an organic resin chain enable the Ti-O-Si nano-structure, which is originally covered in an organic structure, to show good hydrophilicity on the surface. After cooling, due to recovery of the organic resin conformation, the resin will gradually lose super hydrophilicity.

Description

Technical field [0001] The invention relates to a hydrophilic resin, in particular to a thermally induced superhydrophilic resin, as well as a production method thereof. Background technique [0002] Because the hydrophilic surface can quickly spread the water droplets attached to it, it is easy to be wetted by water. In this way, pollutants such as dust on the surface will be washed away with the water due to the buoyancy of the water, its own gravity, wind and other factors, making it easy to clean the surface. Therefore, constructing a superhydrophilic surface by treating the surface with hydrophilicity has an important role in industry. [0003] Hydrophilic treatment is divided into inorganic treatment, organic treatment and organic-inorganic composite treatment. Generally speaking, inorganic treatment is cheap and the coating film has good hydrophilicity, but the coating film has poor corrosion resistance and mechanical properties, and it is easy to wear molds during process...
