preparation example Construction

[0028] One aspect of the present invention provides a kind of preparation method of glass solder, comprises the following steps:

[0029] a) Ball milling: ball milling the packaged glass sheet to make glass powder;

[0030] b) Forming: pressing the glass powder to form a solder blank;

[0031] c) Sintering: the solder body is sintered to obtain the glass solder.

[0032] In the preparation method provided by the present invention, the glass powder obtained after ball milling is directly pressed into shape, avoiding the use of organic matter such as binders, thus avoiding the problem of changing the properties of the glass powder due to the addition of binders, and avoiding the Environmental pollution and harm to the human body caused by volatilization of the adhesive during use.

[0033] In a preferred embodiment of the present invention, the particle size of the glass powder after ball milling is 2-10 microns.

[0034] In a preferred embodiment of the present invention, th...

Abstract

The invention provides a glass welding material and a preparation method thereof, and relates to the field of welding materials. The preparation method of the glass welding material comprises the following steps of (1) ball milling: performing ball milling on a packaged glass sheet to prepare glass powder; (b) forming: pressing the glass powder to form a welding material blank; (c) sintering: sintering the welding material blank, so as to obtain the glass welding material. The glass welding material has the advantages that no adhesive is contained, the technical problems of change of original characteristic of the glass powder due to adding of adhesive into the glass welding material and easiness in pollution to environment and harm to body health in the use process in the prior art are relieved, the original characteristic of the glass powder is guaranteed, and the pollution to the environment and harm to the body health due to volatilizing of the adhesive in the use process are avoided.

Description

technical field [0001] The invention relates to the technical field of welding materials, in particular to a glass solder and a preparation method thereof. Background technique [0002] With the development of science and technology, the technology of packaging with glass solder has become an indispensable technology for manufacturing various high-quality electric light sources, high-vacuum electron tubes and other optoelectronic devices, and the materials that can be packaged with glass solder are also increasing, such as various Various metals and alloys, various ceramics and glass, etc. Glass solder-metal packages are widely used in batteries, electronics, automobiles, home appliances, medical, lighting, instrumentation, military and other industries due to their excellent properties such as good sealing, pressure resistance, and corrosion resistance. [0003] According to the crystallization performance of glass solder, it can be divided into non-crystalline glass solde...
