Abstract

The invention discloses a super-hydrophobic icing-preventing coating material. The material comprises the following raw materials by weight: 40 to 45 parts of fluorocarbon resin, 0.4 to 0.5 part of hyperbranched polyester, 24 to 32 parts of SiO2, 8 parts of TiO2, 50 to 80 parts of a solvent, 1.224 to 1.705 parts of a coupling agent KH-602, 1.836 to 2.558 parts of an antifoaming agent, 0.808 to 1.01 parts of a dispersant 1.224 to 1.705 parts of a wetting agent, and a curing agent IPDI trimer. The preparation method comprises the following steps: (1) adding the hyperbranched polyester, the fluorocarbon resin, the coupling agent and the solvent into a container in proportion, carrying out high-speed mechanical stirring for 10 min, then adding the antifoaming agent, the wetting agent and the dispersant, continuing stirring for 3 h, then adding SiO2 and TiO2, carrying out high-speed mechanical stirring for 4 h so as to obtain a mixture, putting the mixture into a cone mill and grinding the mixture; and (2) adding IPDI into the ground mixture and carrying out uniform mixing so as to obtain the super-hydrophobic icing-preventing coating material.

Description

technical field [0001] The invention relates to a coating material, in particular to a super-hydrophobic anti-icing coating material and a preparation method thereof. Background technique [0002] The hydrophobicity of the hydrophobic coating is mainly related to the wettability of the coating, and the contact angle is usually used to characterize the wettability of the liquid to the solid. A superhydrophobic coating refers to a surface where the static water contact angle between water and the substrate is greater than 150° when a water droplet falls onto a clean substrate surface. The existing water-transporting coatings have poor ability to resist condensation of water and ice, and are difficult to be used in various special environments. Contents of the invention [0003] The present invention aims to solve the above-mentioned deficiencies, and provides a superhydrophobic anti-icing coating material and a preparation method thereof. [0004] The above object of the p...
