Abstract

The invention discloses an anti-icing paint. The paint comprises a component A and a component B in a mass ratio of (4-7):1, wherein the component A is prepared from the following ingredients in percentage by mass: 20-80 percent of fluorosilicon resin with solid content of 20-70 percent, 0.05-2 percent of a defoaming agent, 0.05-2 percent of a flatting agent, 0.05-2 percent of a rheological agent, 0.05-5 percent of a light stabilizer, 0.05-2 percent of a matting agent, 0.05-2 percent of drier, 10-60 percent of rutile titanium dioxide, 0.1-20 percent of a dispersant and 20-70 percent of a solvent A; and the component B is prepared from the following ingredients in percentage by mass: 20-80 percent of a polyisocyanate curing agent and 20-80 percent of a solvent B. The anti-icing coating formed by the anti-icing paint has low surface energy and good hydrophobicity, can be used for effectively reducing the ice adhering strength of a base material, has excellent weather resistance and abrasion resistance, has high hardness and strong adhesive force to the base material, can be applied to wind blades, electric wires and cables and other cold surfaces with anti-icing requirement, and can be used for effectively relieving the icing phenomenon of cold surfaces, guaranteeing efficient working of the wind blades, the electric wires and cables and the like and prolonging the service lives of the wind blades, the electric wires and cables.

Description

technical field [0001] The invention relates to the technical field of paint chemical industry, in particular to an anti-icing paint and its preparation method and application. Background technique [0002] The icing phenomenon of equipment such as wind power, communication, electric power, aviation and transportation brings a lot of inconvenience to people's production and life, and in severe cases, it will cause major economic losses. Therefore, how to solve the problem of icing on the surface of key components has always been a research hotspot at home and abroad. . [0003] For example, wind energy, as a green, non-polluting and sustainable new energy source, has become an important part of human energy. The surface of wind turbine blades is easy to freeze in winter, which affects the dynamic balance of wind turbines. However, the wind turbine blades rotate at a high speed and have a large centrifugal force. In the case of serious imbalance, the blades will break, causi...
