Abstract
The invention discloses the preparation method of a kind of gas sensing resistance unleaded environmental protection glass dust, its concrete preparation process is: (1) tentatively pulverizes: silicon dioxide, zinc oxide, zirconium dioxide and boron oxide are mixed, the pure water of the quality such as addition, it is placed in agitation grinding equipment after attrition grinding, takes out to insert in vacuum drying oven and dry；(2) melt water quenching: the mixed powder handled well in step (1) is placed in melted kiln heating and founds, after powder to be mixed is completely melted, adds pure water and carries out shrend, after the most again repeating melt water quenching process, and natural cooling；(3) pulverizing: insert in ball-grinding machine by cooling down complete compound in step (2), after adding pure water grinding, insert in vacuum drying oven and dry, the powder after drying obtains glass dust through Vibration Screen again；The invention has the beneficial effects as follows: formula uses lead-free recipe, obtains not resulting in glass dust preparation process later serious toxic pollution, and the glass powder particles of preparation is uniform.
Description
Technical field
The present invention relates to electronic component dispensing preparing technical field, particularly a kind of gas sensing resistance unleaded environmental protection glass dust
Preparation method.
Background technology
Gas sensing resistance is that after utilizing certain gas of some semiconductor absorber, generation redox reaction is made, and main component is
Metal-oxide, principal item has: metal-oxide gas sensing resistance, composite oxides gas sensing resistance, pottery gas sensing resistance etc..
Gas sensing resistance, in preparation process, needs to configure glass dust, and glass dust can connect in preparation sintering process, draw
Tightly, fix conductive phase particle, and make whole film layer be securely bonded together with matrix.But glass dust preparation is joined the most mostly
Side is all contained lead, either all can cause the biggest pollution in preparation process, use process or last discarded removal process
And murder by poisoning.
Summary of the invention
It is an object of the invention to, for solving the problems of the prior art, disclose a kind of gas sensing resistance unleaded environmental protection glass
The preparation method of powder.
For achieving the above object, the invention discloses the preparation method of a kind of gas sensing resistance unleaded environmental protection glass dust, press
Mass percent takes silicon dioxide 55%, zinc oxide 20%, zirconium dioxide 10%, boron oxide 15%, and its concrete preparation process is:
(1) tentatively pulverize: silicon dioxide, zinc oxide, zirconium dioxide and boron oxide are mixed, the pure water of the quality such as addition, be placed in
In agitation grinding equipment after attrition grinding 1-2 hour, take out to insert in vacuum drying oven and dry 20-25 minute, dry temperature and set
For 140-160 DEG C；
(2) melt water quenching: the mixed powder handled well in step (1) being placed in melted kiln heating and founds, glass melting temperature sets
1300-1500 DEG C, after powder to be mixed is completely melted, adds pure water and carry out shrend, the most again repeat to melt-shrend process 1-
After 3 times, natural cooling；
(3) pulverize: insert in ball-grinding machine by step (2) cools down complete compound, add mixture quality 1-1.5
After pure water again, after grinding 3-5 hour, insert in vacuum drying oven and dry 30-40 minute, dry temperature and be set as 180-200 DEG C,
Powder after drying obtains glass dust through Vibration Screen again.
Advantages of the present invention and good effect be:
The inventive method formula uses lead-free recipe, obtains not resulting in glass dust preparation process later serious poisonous
Evil is polluted, and is allowed to the most relatively environmental protection after using and discarding of rear gas sensing resistance, and this method technological parameter arranges rationally, preparation
Glass powder particles is uniform.
