Abstract

The invention discloses cleaning water-based paint with a bionic self-lubricating effect, and a preparation method thereof. By utilizing the characteristic that the surface is self-lubricated through a common nepenthes imitating effect, and adopting a mode of loading silicone oil on aerogel, a silicone oil lubricating fluid with the lubricating effect is sealed into a water-based resin paint base material; by combining adsorption of an aerogel porous structure and transfer behaviors, on a water-based resin surface, of silicone oil, the controlled release effect, on the surface of the water-based paint base material, of the silicone oil lubricating oil is achieved, and long-time self-lubricating cleaning effect is achieved. According to the preparation method, a super-hydrophobic rough surface is not needed to be constructed; the prepared paint has self-cleaning effect, good stability, environmental protection and no pollution; the preparation method is simple, is innovative, is high in implementation, and is more beneficial to industrial application.

Description

technical field [0001] The invention relates to a water-based paint and a preparation method thereof, in particular to a cleaning water-based paint with bionic self-lubricating effect and a preparation method thereof. Background technique [0002] Self-cleaning coatings (cleaning coatings) have the advantages of water saving, energy saving, and environmental protection, and have attracted more and more attention from people. At present, most of them realize the self-cleaning function of coatings by constructing biomimetic superhydrophobic coatings on the surface, which are mainly realized by modifying low surface energy substances on rough surfaces and improving the roughness of low surface energy substances. However, most of the superhydrophobic surfaces reported so far have problems such as complex preparation process, harsh conditions, expensive equipment, high production cost, and poor stability, which greatly reduce their practical value. In addition, self-cleaning coa...
