Problems solved by technology

[0006] The present invention aims to overcome the existing anti-icing coatings. With the aging and degradation of the polymer matrix in the coating and the pollution of hydrophilic pollutants, the hydrophobicity of the coating surface will be destroyed, resulting in an anti-icing coating on the coating surface. To solve the problem of insufficient ice persistence, a two-component water-based long-lasting anti-icing coating is provided. The silicone oil is loaded in a slow-release carrier, and the controlled release and slow release of the silicone oil are realized through the mixed use of the two components, thereby prolonging the coating. The duration of the layer's hydrophobic properties, so that the coating has long-term anti-icing performance

Abstract

The invention discloses a double-component water-based long-acting anti-icing coating. The coating comprises a component A and a component B which are independently packaged and mixed according to a mass ratio of 25: (1-2) in use. The component A comprises the following raw materials in parts by weight: 90 to 100 parts of an organic silicon rubber emulsion with a solid content of 40 to 60 wt%, 5 to 10 parts of n-tetradecane, 15 to 20 parts of a filler, 0.5 to 1 part of a catalyst, 1 to 5 parts of a leveling agent, 0.2 to 0.4 part of a defoamer, 3 to 5 parts of sodium carbonate and 50 to 70 parts of water. The component B comprises the following raw materials in parts by weight: 20 to 40 parts of an organic silicon crosslinking agent, 10 to 30 parts of a silane coupling agent and 10 to 30 parts of slow-release silicone oil particles. According to the invention, silicone oil is loaded in a slow-release carrier, and controlled release and slow release of the silicone oil are realized through mixing of the two components, so the lasting time of the hydrophobic property of the coating is prolonged, and the coating is allowed to have long-acting anti-icing performance.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a two-component water-based long-lasting anti-icing coating. Background technique [0002] Snow and icing on the surface of materials is a very common phenomenon in winter. In many fields of the national economy, such as power transmission cables, road traffic, aerospace, navigation, heat exchangers, etc., production is caused by snow and icing of materials every year. Safety accidents and economic losses are very serious, so it is of great significance to find ways to effectively prevent ice disasters from causing damage to transmission lines, road traffic and other fields. [0003] At present, the anti-icing methods in practical application are mainly divided into two categories: active deicing and passive anti-icing. Active deicing refers to the removal of ice by thermal anti-icing melting, mechanical deicing and other methods; passive anti-icing mainly uses anti-icing coatings and ot...
