Abstract
The invention provides a lamp filament material and a preparation technology thereof. The lamp filament material comprises a lamp filament body, and two layers of composite material coated onto the lamp filament body. The lamp filament body is made from a WAl-Co alloy material. In the two layers of composite material coated onto the lamp filament body, the inner layer is an electrically-conductive layer, the outer layer is a molding layer, the electrically-conductive layer is filled with tungsten, iridium and alloy materials thereof, the outer layer molding layer is molded by bonding yttrium oxide and platinum oxide materials with amino glue. According to the invention, advantages of simple technology and available raw materials can be realized, the luminous efficacy of related products can be effectively improved, and the service life of the lamp filament material can be prolonged.
Description
Technical field
The present invention relates to field of material preparation, be specially a kind of possess high strength, long-life filament material and preparation technology thereof.
Background technology
In general, electricity-saving lamp is than ordinary incandescent lamp power saving, its caliber is thin, simple in structure, shape molding is easy, possess the advantages such as surface of the light tube brightness is high, color rendering index is high, the life-span is long, price is low simultaneously, in recent years, obtain very fast development at home and abroad, and within a period of time, become the main flow of back light.
In the preparation process of electricity-saving lamp, the normally refractory metals that adopt of its filament material more, and limit by technology, range of choice is very narrow, and be difficult to break through always, although yet these traditional filament can effectively support related industry, but also exist defect, due to very difficult adjusting of resistance characteristic of the metal adopting, and the density unevenness of moulding material itself, all may cause electric current inconsistent and can not realize Uniform Discharge, finally have influence on lighting quality and the useful life of electricity-saving lamp.
Summary of the invention
Technical problem solved by the invention is to provide a kind of filament material and preparation technology thereof, to solve the shortcoming in above-mentioned background technology.
Technical problem solved by the invention realizes by the following technical solutions:
A kind of filament material, comprise filament body and be wrapped in the two-layer composite material on filament body, wherein, described filament body is WAl-Co alloy material, and is wrapped in this external two-layer composite material of filament, and its internal layer is conductive layer, skin is shape layer, described conductive layer is that tungsten, iridium and alloy material thereof are filled, and outer field shape layer is yittrium oxide, platinum oxide material, by amino glue bonding forming.
Preparation technology based on above-mentioned filament material comprises the following steps:
1, utilize high cobalt and WAl 2 ultra-fine grains to pulverize as raw material separated, by ultra-fine grain cobalt powder, in the wet grinding media such as WAl 2 ultra-fine grains and CaC and absolute alcohol, additional proportion is 1:1, utilize wet milk to carry out wet ball-milling, the wet-milling time is 3 ~ 6 hours.
2, by the mixture vacuumize after wet-milling, compressing and carry out vacuum-sintering 6 ~ 10 hours in 1400 ℃ of kilns, the uniform filament body of interior tissue obtaining.
3, filament body is carried out to electrophoresis, conductive is attached on filament body.
4, by yittrium oxide, platinum oxide and amino glue in mass ratio the ratio of 8:8:1 take and mix, agent is made into and spreads upon filament body surface dry solidification after liquid and obtain finished product.
Beneficial effect: filament material technique of the present invention is simple, with low cost, resistance to bending performance is superior, simultaneously, possesses very strong non-oxidizability, can effectively extend the useful life of filament, and due to filament surface attachment yittrium oxide and platinum oxide, can effectively improve electron emission ability, reduce the power consumption of filament.
