Abstract

The invention discloses an anti-ice paint and a preparation method thereof. The paint comprises a polyacrylate graft PDMS (Poly Dimethyl Siloxane) copolymer containing POSS (Polyhedral Oligomeric SilSesquioxane), a curing agent and a diluent. A coating prepared by utilizing the paint and adopting a paint coating process has the advantages of anti-ice ability, good mechanical property, good compatibility with other materials, good adhesive force and difficulty in dropping. According to the anti-ice paint and the preparation method disclosed by the invention, the preparation process of the paint is simple, and coating of the paint does not need special construction conditions and can be used by matching with a universal acrylics priming paint, so that the using range of the traditional organosilicone anti-ice paint is expanded, and the anti-ice paint can be widely used for the surfaces of outdoor facilities of traffic transportation, oil drilling platforms, electricity systems, communication systems and the like with the anti-ice needs and has an application value.

Description

technical field [0001] The present invention relates to a kind of anti-ice and snow paint and preparation method thereof, particularly relate to a kind of anti-ice and snow paint of the polyacrylate grafting polydimethylsiloxane (PDMS) copolymer containing polysilsesquioxane (POSS) The invention and a preparation method thereof belong to the technical field of acrylate-modified organosilicon hydrophobic anti-icing and snow coatings. Background technique [0002] The adhesion and accumulation of ice may cause serious damage to communication facilities, antennas, aircraft, ships and other outdoor facilities, and even cause huge economic losses and casualties. In recent years, anti-icing technology has become a research hotspot and an important research content in various countries. Anti-icing technology mainly achieves the effect of preventing ice adhesion and accumulation by spraying anti-icing agents and constructing anti-icing coatings. Spraying deicing agents has a short...
