Description

Technical Field

[0001] The invention belongs to the technical field of multifunctional super-slippery surfaces, and more specifically, relates to a super-slippery coating based on organic silicon resin and capable of continuously and automatically releasing lubricating liquid. Background Art

[0002] Super-slippery materials have broad application prospects in the fields of anti-fog and anti-icing, anti-marine fouling biological attachment, antibacterial, metal material corrosion protection, fluid manipulation, optical sensing, etc. due to their low sliding resistance, low adhesion, strong pressure resistance, self-repair function, adjustable light transmittance, lubrication and friction reduction. Traditional super-slippery materials are usually prepared in the following three steps: constructing a rough structure to lock the lubricant, surface modification to reduce the interface energy and increase the stability of the substrate and the lubricant, and injecting the lubricant to make the surface have multifunctional properties. The preparation method relies on micro-nano structures, resulting in the preparation of super-slippery materials with cumbersome processes, high costs, substrate restrictions, difficulty in large-scale preparation, poor mechanical properties, poor stability and durability, which limits its engineering application. The swelling of the polymer coating by the lubricant can slow down the loss rate of the lubricant and extend the service life of the super-slippery coating, but at the same time, the swelling polymer coating sharply reduces the adhesion between the coating and the substrate, causing the coating to fall off.

[0003] Therefore, it is urgent to propose a new super-slip coating. Summary of the invention
