Core-shell anti-ice-freezing modifier, method for producing same, and anti-ice-freezing coating material comprising same

Abstract

The present invention relates to a core-shell anti-ice-freezing modifier, a method for producing the same, and an anti-ice-freezing coating material comprising the same. The core-shell anti-ice-freezing modifier comprises a core and a shell layer, wherein the core is water-soluble metal salt particles; the shell layer is formed of oxide particles and coats the core. The thickness of the shell layer is 10 nm or more. The anti-ice-freezing modifier disclosed by the invention is easy to construct. When used for the anti-ice-freezing coating, an anti-ice-freezing coating layer formed by the anti-ice-freezing coating has excellent anti-ice-freezing property, hydrophobicity, slow release property and long service life.

Description

technical field [0001] The invention relates to a core-shell anti-icing modifier, a manufacturing method thereof and an anti-icing coating comprising the same. Background technique [0002] Snow and ice on roads in winter has always been a problem that plagues road traffic safety. Snow and ice on the road surface will greatly reduce the anti-skid ability of the road surface, which not only weakens the traffic capacity of the road, is prone to vicious traffic accidents, but also damages the road and its subsidiary structures. In severe cases, it will cause traffic interruption and make people's lives Production and production cannot be carried out normally, and even endanger the safety of people's lives and property. [0003] At present, the commonly used road surface deicing methods are generally divided into two categories: passive suppression type and active ice and snow melting type. Commonly used passive suppression ice and snow removal measures mainly include spreadin...

AI Technical Summary

Problems solved by technology

Thereby, there is following problem in prior art: because inorganic salt particle is little (big specific surface area), the consumption of used wax, asphalt or various resin (as patent document 3) can be very big, uneconomical; Adopt this simple The physical way of wrapping, the surface of the particles is difficult to wrap evenly, and the organic matter is sticky, and the wrapped particles will stick together. In order to disperse the bonded particles, the follow-up production workload will be very huge, and it is difficult to achieve real industrialization; further In actual use, it is found that in the case of using polymers to wrap small particles of inorganic salts, the surface of the wrapped inorganic salt particles has more gaps in the wrapping material, and the slow-release effect will be greatly reduced when it meets water.
