Fluorosilicate self-cleaning glass nanophase material and producing method thereof

Abstract

The invention discloses a silicon fluoride self-cleaning glass nano-material, which is composed of solvent and active ingredients; the active ingredients are fluorinated modified silicone nano-particles, and the reaction raw materials comprise ortho-silicon ester and fluorine modified alkyl silane, with the ratio volume and dosage reaching 1.5-3:0.15-1.8. The invention also discloses a manufacturing method for the silicon fluoride self-cleaning glass nano-material, comprising two steps: synthesizing the surface modification of silica nano-particles, silica nano-particles; the ratio between volume and dosage for each added reactant is as follows: solvent: water: ortho-silicon ester: fluorine modified alkyl silane equals to 100: 1.5-3: 1.5-3: 0.15-1.8. The invention has simple production process, stable product performance, higher storage stability, excellent chemical properties, low surface energy and good tolerance against pollution, which is used for glass surface treatment; the contact angle between water and coating is greater than 110 degrees.

Description

technical field [0001] The invention relates to a silicon fluoride self-cleaning glass nano material used for surface treatment of glass, ceramics, etc. to make the surface have dustproof, antifouling and self-cleaning functions and a production method thereof. Background technique [0002] With the continuous development of the modernization of urban construction, the amount of glass curtain walls used in high-rise buildings has increased rapidly. But at present, most of the glass curtain walls have the problem of poor pollution resistance, especially in the northern regions with severe air pollution, drought and little rain, the glass curtain walls are very easy to be dusty, resulting in uneven color and different ripples, making Uncontrollable light reflection leads to cluttered light environment and damages the urban landscape. In addition, it is very difficult to clean the glass curtain wall. The high-strength detergent used in the cleaning process is corrosive to a ce...
