Abstract

The invention relates to a metal organic compound collosol / organic silicone compound icing-proof coating and a preparation method thereof. The preparation method for the metal organic compound collosol / organic silicone compound icing-proof coating is characterized by comprising the steps of: 1) preparing a metal alkoxide by adopting an electrochemical method; 2) preparing the metal organic compound collosol; 3) selecting the metal organic compound collosol, dimethylbenzene, acetone and an organic silicone rubber coating according to the ratio of the metal organic compound collosol to the dimethylbenzene to the acetone to the organic silicone rubber coating of 1g:(1.3-3g):(0.16-0.5g:(3-5.5g); adding the metal organic compound collosol into the organic silicone rubber coating after dissolved with the dimethylbenzene and the acetone and then mixing by stirring, removing bubbles through ultrasonic oscillations and uniformly dispersing the mixture through stirring or grinding to obtain themetal organic compound collosol / organic silicone compound icing-proof coating. The icing-proof coating has good icing-proof effect, and the method has a simple process.

Description

technical field [0001] The invention belongs to the technical field of organometallic chemistry and material surface interface, and in particular relates to a metal organic compound sol / organosilicon composite anti-icing coating and a preparation method thereof. Background technique [0002] Freezing rain will have a serious impact on outdoor facilities such as high-voltage cables, wires, communication equipment, spacecraft, bridges, highways, and airports. In recent years, with the rapid development of the economy, the damage of freezing rain and snow to outdoor facilities has become increasingly serious, which has aroused the close attention of relevant scientific workers from all over the world. Since January 10, 2008, there have been rare and continuous large-scale low temperature, rain, snow and freezing extreme natural disasters in southern China. The power facilities have been damaged on a large scale, and the power grid structure has been severely damaged, causing 16...
