Abstract

The invention discloses a double-component fluorosilicone rubber ice-covering-proof coating material and a preparation method thereof. The preparation method comprises the following steps: dissolving fluorine-containing acrylate in solvent, adding a platinum catalyst, uniformly stirring, and pouring into a four-neck flask; starting an electromagnetic stirrer, introducing inert gas, heating in water bath, adding hydrogen-containing silicone oil, and reacting to generate fluorine modified silicone oil; placing vinyl terminated polydimethylsiloxane in a beaker, adding 5-40 parts by mass of white carbon black used as reinforcement filler, evenly stirring, then adding 0.5-5 parts by mass of whitener TiO2, and evenly stirring; weighing 1-5 parts by mass of hydrogen-containing silicone oil and 1-5 parts by mass of fluorine modified silicone oil, placing in the beaker, evenly stirring, adding 10-50mu L of platinum catalyst, and finally adding the solvent; and evenly coating through a spin coater, and curing in a baking oven for 1-4 hours, thus obtaining the double-component fluorosilicone rubber coating. The invention overcomes the defects in the prior art, uses polyorganosiloxane as the raw material, can achieve satisfactory ice-covering-proof effect and is used in the fields of paint and the like.

Description

technical field [0001] The invention belongs to the field of organic fluorosilicon materials, and more specifically relates to a two-component fluorosilicon rubber anti-icing coating material and a preparation method thereof. Background technique [0002] Snow or ice accumulates on the surface of transmission lines, aircraft and other outdoor facilities, which can easily cause major accidents such as downed poles (towers) of transmission lines, disconnection, and aircraft crashes, resulting in inestimable losses. At present, more than 30 anti-icing technologies have been developed, such as heat treatment method, mechanical deicing method, anti-icing coating method, etc., but the anti-icing problem has not been completely solved. [0003] Among these anti-icing technologies, the anti-icing coating method is the most simple and easy to implement, and the cost is low, so it has attracted more and more attention of researchers. At present, the available anti-icing technologies ...
