Abstract

The invention discloses an anti-icing single-component fluorosilicone rubber coating material and a preparation method thereof. The preparation method comprises the steps of taking alpha, omega-dyhydroxyl polydimethyl siloxane as basic rubber, and preparing an anti-icing single-component fluorosilicone rubber coating by changing the relative content of a cross-linking agent and a fluorine-containing cross-linking agent. The anti-icing single-component fluorosilicone rubber coating material and the preparation method thereof aim at overcoming the defects in the prior art and used for the fields of paint and the like, organopolysiloxane is taken as a raw material, and a better anti-icing effect can be achieved.

Description

technical field [0001] The invention belongs to the field of organic fluorosilicon materials, and more specifically relates to a one-component fluorosilicon rubber anti-icing coating material and a preparation method thereof. Background technique [0002] Icing is formed by the combination of very complex weather processes and microphysical processes. According to the conditions of formation and the degree of damage, there are basic types such as rime icing, mixed rime icing, ice rime icing, hoarfrost, and snow. . Mixed rime is a composite icing process, firstly rime, then rime, which is a form of alternating ice, which grows faster and is particularly harmful. [0003] At present, the available anti-icing technologies are mainly divided into two categories, active deicing and passive anti-icing. Active deicing includes spraying deicing agents to lower the freezing point, point heating to melt the ice body, etc. Building an anti-icing coating to prevent ice adhesion and ac...
