Preparation method of long-chain SiO2 powder with micro-nano structure

Abstract

The invention relates to a preparation method of a long-chain SiO2 powder with micro-nano structure. At present, development of a superdouble hydrophobic material is faced with a few problems, the superdouble hydrophobic material cannot be prepared and popularized on a large scale, the problems of harsh experimental conditions, tedious steps, high cost and the like exist in most of preparation methods, and engineering application cannot be realized. According to the preparation method of the long-chain SiO2 powder with micro-nano structure, the long-chain SiO2 powder comprises chain carbon powder subjected to silane surface modification, carbon in the chain carbon powder subjected to silane surface modification disappears after the chain carbon powder subjected to silane surface modification is subjected to heating treatment in the air at 400 to 700 DEG C, the long-chain silicon dioxide with the micro-nano structure is obtained, and the long-chain silicon dioxide serves as a super-hydrophobic olephobic coating filler. The invention is applied to the preparation method of the long-chain SiO2 powder with the micro-nano structure.

Description

technical field [0001] The invention relates to a preparation method of long-chain SiO2 powder with micro-nano structure. Background technique [0002] Superhydrophobic technology is a new type of technology with special surface characteristics. It has important characteristics such as waterproof, snowproof, antifog, antioxidation, antipollution, anticorrosion, self-cleaning, and prevention of current conduction. It is widely used in scientific research, life, production, etc. There are extremely broad application prospects in the field. Super oleophobic technology can make oil repel on the surface of super oleophobic coating. This technology can be used for the separation of oil to reduce the loss of crude oil, and it can be used for oil pipelines to maximize the use of oil, and it can also be placed on the surface of the exhaust fan to keep it clean, etc. Superhydrophobic and oleophobic materials, that is, superamphiphobic materials, belong to the emerging nanomaterials ...

AI Technical Summary

Problems solved by technology

[0003] At present, the development of super-amphiphobic materials is facing several major problems, resulting in the inability of large-scale preparation and popularization of super-amphiphobic materials. Most of the preparation methods still have problems such as harsh experimental conditions, cumbersome steps, and high costs, which cannot be applied in engineering.

The superamphiphobic materials that have been put into the market also have disadvantages such as low surface microstructure strength, easy aging, easy wear, easy pollution, and short service life.
