Problems solved by technology

[0003] At present, there are mainly four deicing methods: ① mechanical deicing, through manual or appropriate deicing machinery to knock deicing, this method is low in cost, but labor-intensive and low in efficiency, such as bogie deicing in cold weather
② Sprinkle anti-icing agent, by spraying anti-icing agent on the surface of the base material to lower the freezing point, this method will pollute the soil and corrode the road surface, so it can only be applied temporarily, the time limit is short, and the environmental pollution is great
[0004] Anti-icing coatings are mostly fluorine / silicon (super) ice-phobic coatings with low surface energy, such as R-2180 produced by Nusil, Mega Guard Liqui Cote coatings from Kiss-cote, RIP-4004 from S&A Fernandina etc. These anti-icing coatings can indeed greatly reduce the icing strength, but they cannot really prevent icing
Chinese patent 201510473839.1 and patent 201710237931.7 respectively report the method of electrothermal deicing, both of which use the hydrophobic effect of the surface coating and the electric heating of the bottom coating to comprehensively prevent deicing, but the cost is high, the process is cumbersome, and it is difficult to use in large areas

Abstract

The invention provides an electric-heating self-lubricating ice-prevention and deicing coating as well as a preparation method and application thereof, belonging to the technical field of ice-prevention and deicing materials. The electric-heating self-lubricating ice-prevention and deicing coating contains a component A and a component B. By virtue of the interaction of raw materials in the component A and the component B, the surface icing can be delayed based on the excellent self-lubricating property of an electric-heating self-lubricating ice-prevention and deicing coating layer, and the surface adhesive strength of ice is reduced; and by applying a relatively low voltage to the coating layer, the coating layer can be rapidly heated, and the ice on the surface of the coating layer canbe melted and removed. Furthermore, a production process of the electric-heating self-lubricating ice-prevention and deicing coating is simple and low in cost and can meet the demands of industrial production.

Description

technical field [0001] The invention relates to the technical field of anti-icing materials, in particular to an electrothermal self-lubricating anti-icing coating and a preparation method and application thereof. Background technique [0002] Freezing in winter often brings a lot of inconvenience to people's daily production and life, and sometimes even brings serious harm to the operation of mechanical equipment. Ice accumulation on the surfaces of aircraft wings, high-speed train bogies, wind power blades, radar signal towers, ship decks, offshore oil development platforms, etc. seriously affects the working efficiency and service life of mechanical components, and even causes casualties. Especially the ice and snow disaster in the south in 2008 made us realize the harm of ice accumulation to power transmission lines. The icing turns the thin wires into heavy "icicles", which increases the load on the iron towers supporting the high-voltage wires, seriously causing the t...
