Method for preparing radiation-proof glass by silver composite target and product

Abstract

The invention provides a method for preparing radiation-proof glass by a silver composite target and a product. The preparation method includes the steps: pelleting raw silver to form silver particles; dispersedly mixing 95-99.72% of the silver particles, 0.2-3% of niobium, 0.03-1% of nano-titanium dioxide and 0.05-1% of nano-zinc oxide in weight percent; ball-milling mixed powder to obtain mechanical alloy powder; pressing, hot-pressing, sintering, cold-rolling, annealing and machining the mechanical alloy powder to obtain the silver composite target; sputtering the silver composite target on the surface of a transparent substrate to prepare the radiation-proof glass. The radiation-proof glass prepared by the method has high visible light penetrating capacity and low ultraviolet / infrared light penetrating capacity.

Description

technical field [0001] The invention belongs to the technical field of target material production, in particular to a method for preparing anti-radiation glass by adopting a silver composite target material and a product thereof. Background technique [0002] With the development of the economy, the use of glass in the construction industry continues to increase. In modern architecture, in addition to considering aesthetics and appearance features, more attention is now paid to the overall balance of how to control heat, indoor cooling costs, and interior sunlight projection comfort. At present, the problem of energy shortage has become more and more prominent, and how to reduce the energy consumption required for cooling buildings has become a common concern. [0003] For this reason, anti-radiation glass (that is, LOW-E glass) came into being. This product is made by coating the glass surface with a multi-layer metal film. Its coating layer has the characteristics of h...

Problems solved by technology

[0005] Therefore, the existing LOW-E glass preparation process has the following disadvantages: (1) It is necessary to use multiple cathode plates with different targets and the cathode plate control system, which results in a huge process and equipment. Cost expenditure; (2) Most of the silver targets on the market are silver targets prepared by vacuum casting method. Due to the limitation of the volume of the vacuum cavity in vacuum casting and the uneven cooling of casting, the length and width of these silver targets The size is generally only 600~1000mm, which cannot meet the needs of large-size radiation-proof glass products with a length or width greater than 1000mm

Therefore, in order to solve the problem that the size of the existing silver target is too small, the industry often uses multi-piece target splicing to produce the silver target of the required size. The process will affect the uniformity of the plasma, and may cause local abnormal discharge of the target, thereby reducing the quality and pass rate of the coated product. In addition, the more the number of splicing, the more difficult the quality consistency between the pieces, and finally It will also reduce the uniformity of the film layer and product quality
