Self-cleaning type tempered glass and manufacturing method thereof

Abstract

The invention discloses self-cleaning type tempered glass and a manufacturing method thereof. An essential body is prepared from the following components in parts by weight: 85 to 90 parts of silicondioxide and 10 to 15 parts of sodium oxide; one layer of hydrophilic cured film composed of starch grafted sodium acrylate is further attached on the surface of the essential body; one layer of silicon dioxide micro-powder which is densely arrayed and has the diameter of 5mu m to 8mu m is further integrated on the outer surface of the hydrophilic cured film. The self-cleaning type tempered glass disclosed by the invention is obtained by the steps of firing the pure raw materials and carrying out physical tempering, carrying out lotus effect bionic modification on the surface of a hydrophilic film layer after the hydrophilic film layer is compounded and finally obtaining a product. The self-cleaning type tempered glass disclosed by the invention has the advantages that the surface has a lotus effect and can automatically adsorb water beads, and the self-cleaning type tempered glass has good light transmission performance, good anti-impact performance and uneasiness of being deformed anddiscolored.

Description

technical field [0001] The invention relates to the field of glass products, in particular to a self-cleaning tempered glass and a manufacturing method thereof. Background technique [0002] Tempered glass, that is, glass with compressive stress on the surface, can be obtained by physical or chemical methods in conventional technology. When the glass is subjected to external force, the surface stress is first offset, thereby improving the bearing capacity and enhancing the glass's own resistance to wind pressure, cold and heat, and impact. sex etc. In this way, there is no sharp edge when the glass breaks, and the safety is better. [0003] However, with the development of the times, the degree of specialization of glass is getting higher and higher, and some high-rise buildings need self-cleaning (no later maintenance and cleaning) tempered glass due to the consideration of operation and long-term maintenance costs. The self-cleaning glass in the prior art Type glass main...

Problems solved by technology

[0003] However, with the development of the times, the degree of specialization of glass is getting higher and higher, and some high-rise buildings need self-cleaning (no later maintenance and cleaning) tempered glass due to the consideration of operation and long-term maintenance costs. The self-cleaning glass in the prior art Type glass mainly includes composite hydrophobic film (drainage, such as surface wax treatment), composite hydrophilic film (by absorbing water molecules to form large water droplets, which slide freely under the action of gravity, and remove dust by the way), surface mirror treatment (reduce the attached Focus on) and other three methods, but no matter which method has its limitations: the hydrophobic surface treatment is easy to absorb organic molecules such as oil and dust and other solids, and is easy to age and fail; the hydrophilic surface forms large water molecules, which can only In local molding, striped water marks will eventually be formed, and the aesthetics is also poor. The water droplets adhere to the glass surface during the aggregation period before sliding down, severely affecting the imaging performance, and the organic film is also prone to damage under the combined action of sunlight and water molecules. Aging failure; on the one hand, the surface mirror treatment has high process cost, on the other hand, it has no self-cleaning ability. Although the adhesion is low, there are glass-friendly organic substances (such as oil) that are easy to adhere to the surface. There will be problems with cleaning and maintenance; the most important thing is that all self-cleaning glass is not tempered, with low service life, high tendency to thermal cracking and poor impact resistance, which poses a great safety hazard when used in high-rise buildings
