Abstract

The invention relates to glass powder, which comprises the following components in parts by weight: 50 to 80 parts of Bi2O3, 1 to 9 parts of ZnO, 2 to 28 parts of B2O3, 0.1-4 parts of Al2O3, and 0.05 to 2 parts of MgO.

Description

A kind of glass powder
Technical field
The present invention relates to a kind of glass powder.
Background technology
Traditional glass powder for silver electronic paste, the objectionable impurities such as how leaded, cadmium, and its welding temperature is at about 230 DEG C.On July 1st, 2006; European Union " about being limited in electronic and electrical equipment the instruction using some objectionable constituent " (RestrictionofHazardousSubstances) starts formally to implement; this standard is mainly used in the material and progress standard of specification electronic and electrical equipment, makes it advantageously in HUMAN HEALTH and environment protection.The object of this standard is to eliminate the objectionable impurities such as lead, cadmium in motor electronic product.So far, reduce the consumption of the objectionable impuritiess such as lead, cadmium in silver electronic paste and auxiliary material thereof, or develop the silver electronic paste of not leaded, cadmium and so on objectionable impurities and auxiliary material thereof and become the direction that development & production mechanism of various countries puts forth effort to move ahead.After this standard is implemented, in ceramic condenser welding lead process, a large amount of welding compound used changes Pb-free solder into by leaded scolding tin, and welding temperature also brings up to 250 DEG C ~ more than 260 DEG C from 230 DEG C, this just proposes the glass powder used as caking agent and removes plumbous, cadmium and the requirement of high temperature resistant welding.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of excellent property, low-melting glass powder.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of glass powder, and it comprises each component of following parts by weight: 50 ~ 80 parts of Bi 2o 3, 1 ~ 9 part of ZnO, 2 ~ 28 parts of B 2o 3, 0.1 ~ 4 part of Al 2o 3, 0.05 ~ 2 part of MgO.
Preferably, each component of following parts by weight is comprised: 65 parts of Bi2O3,5 parts of ZnO, 15 parts of B2O3,2 parts of Al2O3,1.2 parts of MgO.
Compared with prior art, the invention has the beneficial effects as follows: the present invention is not leaded, cadmium etc. is harmful to the material of HUMAN HEALTH and environment, to the welding of high temperature lead-free solder, there is very strong adaptability, chemical stability and wettability improve, the coefficient of expansion increases, melting temperature sealing and softening temperature reduce simultaneously, can be applicable to electric slurry and make bonding phase, significantly reduce production cost.
Embodiment
Below in conjunction with embodiment, the present invention is further illustrated.
The invention discloses a kind of glass powder, it comprises each component of following parts by weight: 50 ~ 80 parts of Bi 2o 3, 1 ~ 9 part of ZnO, 2 ~ 28 parts of B 2o 3, 0.1 ~ 4 part of Al 2o 3, 0.05 ~ 2 part of MgO.
Preferably, each component of following parts by weight is comprised: 65 parts of Bi2O3,5 parts of ZnO, 15 parts of B2O3,2 parts of Al2O3,1.2 parts of MgO.
Obviously, the above embodiment of the present invention is only for example of the present invention is clearly described, and is not the restriction to embodiments of the present invention.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments.All any amendments done within the spirit and principles in the present invention, equivalent to replace and improvement etc., within the protection domain that all should be included in the claims in the present invention.
