Problems solved by technology

[0003] The anti-icing / frost in the related art mainly adopts super-hydrophobic surface treatment, such as a super-weather-resistant, wear-resistant and anti-icing wind power blade coating disclosed in Chinese patent CN103013316A and its preparation method is an organic-inorganic system coating, which uses fluorine Carbon resin and polyester resin are used as film-forming materials, supplemented with nano-fillers and dispersants to prepare wear-resistant, weather-resistant and anti-icing wind turbine blade coatings. These surfaces can achieve resistance through certain surface morphology control and low surface energy substances. External pollution or pollutants are easy to clean, but the hydrophobic surface cannot meet the anti-icing performance requirements for a long time, and the anti-icing effect decays significantly after repeated use
Chinese patent CN103194130A discloses an anti-icing coating prepared with acrylic resin supplemented with inorganic fillers. It needs external forces such as wind or gravity to remove the ice layer to achieve the anti-icing effect, which can only accelerate the rapid detachment of the ice layer.
Therefore, the anti-icing coating of the related art has the disadvantages of poor anti-icing performance and weak continuous anti-icing effect

Abstract

The invention provides water-based anti-freezing paint. The paint is prepared from, by weight, 10-30 parts of water-based resin, 2-4 parts of curing agent, 0-30 parts of functional filler, 0.05-0.15 part of auxiliary, 1-20 parts of cosolvent and 16-86 parts of water, wherein the sum of weight parts of the materials is 100. Compared with correlative techniques, the paint has the advantages of being strong in anti-freezing performance and remarkable in continuous anti-freezing effect.

Description

【Technical field】 [0001] The invention relates to the technical field of coatings, in particular to a water-based anti-icing coating and a preparation method thereof. 【Background technique】 [0002] In transportation, aerospace, heat exchange, power communication and many other fields, icing / frost has brought great harm and potential safety hazards to human beings and society. Although the existing anti-icing methods such as mechanical deicing, heating deicing and spraying chemical reagents are effective, they have problems such as large energy consumption, environmental pollution and poor durability. The use of anti-icing functional coatings to modify the surface of substrates is convenient and effective, and sacrificial coatings, ice-phobic coatings and super-hydrophobic coatings have become research hotspots. [0003] The anti-icing / frost in the related art mainly adopts super-hydrophobic surface treatment, such as a super-weather-resistant, wear-resistant and anti-icing...
