Abstract
The invention relates to lead-free low-melting point glass powder and a production process thereof. A formula of the lead-free low-melting-point glass powder comprises a component A and a component B, wherein the component A comprises the following raw materials by mass ratio: SiO2 2-28, CaO 27-40, ZnO 2-7, B2O3 1-11, Na2O 1-4, K2O 1-3, F<-> 1-2, MgO 0.1-3, Sb2O3 1-2, MoO3 0.5-5, WO3 0.5-5 and Li2O 1-5; the component B is thermal expansion regulating powder; and the mass ratio of the component B to the component A is 1:4-2:3. The invention has the advantages of improving the formula on the basis of a production technology of the traditional low-melting-point glass and then forming into powder through melting, water quenching and ball-milling processes, thereby meeting the requirements on lead-free environmental protection and lower softening temperature and working temperature.
Description
Technical field
The invention belongs to field of inorganic materials, especially a kind of lead-free glass powder with low melting point and production technique.
Background technology
Low melting glass, can be used as the welding material of glass, be widely used in the sealing-in of elements such as electron devices such as sylvatron, electron tube and semi-conductor, aspect such as bonding, also can be used in occasions such as linking between the glass material, plane defect reparation, from beginning occurring, existing multiple kind, performance difference is bigger.
Initial low melting glass often contains poisonous metals such as lead, cause environmental pollution and direct labor's actual bodily harm easily, though low melting glass has afterwards improved this defective, but still performing poor aspect low temperature softening and the low-temperature working, often need higher temperature to soften and to trickle, thereby realize welding.
Summary of the invention
The objective of the invention is to the deficiency of above-mentioned technology, and a kind of lead-free glass powder with low melting point and production technique are provided.
The present invention solves the technical scheme that its technical problem adopts: this lead-free glass powder with low melting point, prescription is made up of A component and B component, and wherein the quality proportioning of each raw material is in the A component: SiO2:2～28, CaO:27～40, ZnO:2～7, B2O3:1～11, Na2O:1～4, K2O:1～3, F-:1～2, MgO:0.1～3, Sb2O3:1～2, MoO3:0.5～5, WO3:0.5～5, Li2O:1～5; The B component is that powder is regulated in thermal expansion, and the quality proportioning of B component and A component is 1: 4～2: 3.
It is nepheline or pyroxene that powder is regulated in described thermal expansion.
The production technique of this lead-free glass powder with low melting point of the present invention comprises that step is as follows:
(1), the A component is prepared, adopting crucible heat under 1100～1300 ℃ of environment and make it to melt is glass metal by above-mentioned quality proportioning;
(2), glass metal is poured into typing in the ready mould, shrend, broken glass piece;
(3), add the thermal expansion of B component and regulate powder, grind to form powdery with the agate shredder;
The finished glass powder of (4), screening, the required order number of extraction.
The effect that the present invention is useful is: prescription and production technique that a kind of glass powder with low melting point is provided, on the basis of the production technology of existing low melting glass, prescription is improved, technology by thawing, shrend, ball milling again, make it to form powdery, realize leadless environment-friendly, softening temperature and the lower requirement of working temperature.
