Super-hydrophobic anti-fouling anti-icing water-based paint

Abstract

The invention relates to the technical field of material surface engineering, in particular to a super-hydrophobic anti-fouling anti-icing water-based paint which comprises the following components in parts by weight: 10-15 parts of fluoride-grafted nano silicon dioxide on the surface, 40-60 parts of perfluorodecyltrimethoxysilane, 10-20 parts of carbon microspheres, 5-8 parts of modified graphene, 30-40 parts of binder and 100-150 parts of solvent. According to the super-hydrophobic anti-fouling anti-icing water-based paint, the super-hydrophobic material and the near-infrared photothermal material are added, so that the super-hydrophobic anti-fouling anti-icing water-based paint has the dual effects of super-hydrophobicity and photothermal deicing, and the near-infrared photothermal material is modified graphene which is a compound of graphene and CdS; and the super-hydrophobic material is very beneficial to formation of a rough micro-nano structure on the surface of the coating, so that the coating can obtain a larger static contact angle and a smaller rolling angle, the icing time of water drops on the surface of the coating is further prolonged, and a better anti-icing effect is achieved.

Description

technical field [0001] The invention relates to the technical field of material surface engineering, in particular to a super-hydrophobic anti-fouling anti-icing water-based coating. Background technique [0002] The formation and accumulation of ice can easily cause fatal damage to equipment, such as wires and cables, aircraft engines, wind turbines, etc. In 2008, the southern part of my country encountered a rare ice disaster. The precipitation and icing caused by the continuous low temperature caused the paralysis of large-scale and long-term power transmission networks and communication lines, as well as the interruption of major transportation arteries such as roads and railways. According to the data released by the Ministry of Civil Affairs, in 2008, the direct economic loss of my country's ice disaster was as high as 151.65 billion yuan. Therefore, for the research and application of anti-icing on the surface of transmission lines, the preparation of functional coa...
