Abstract

The invention discloses a glass bead for fixing an incandescent lamp filament and a preparation process of the glass bead, and belongs to the field of incandescent lamp materials. The preparation process of the glass bead for fixing the incandescent lamp filament comprises the following steps: step 1, obtaining a glass frit: weighing materials, mixing the materials through a ball mill, and then putting the materials into a crucible for melting and pouring the molten glass into deionized water; and 2, preparation of a glass preform: drying the glass fragments obtained in step 1, crushing the dried glass fragments by using a ball mill, preparing glass powder into a slurry by using an organic matter as a binder, granulating the slurry by using a spray granulator, pressing the granulated slurry into a glass tube green body by using a mold, slowly heating the glass tube green body by using a glue discharge furnace, discharging glue, and sintering the green body to form the glass preform. According to the glass bead for fixing the filament of the incandescent lamp and the preparation process of the glass bead, a new glass formula without toxic components is adopted, glass powder is obtained, glass granulation powder is prepared by adding glue, and then the glass bead or the glass tube suitable for fixing the filament is prepared by a blank pressing and glue discharging process.

Description

technical field [0001] The invention relates to the field of packaging materials for incandescent lamps, in particular to a glass bead for fixing filaments of incandescent lamps and a preparation process thereof. Background technique [0002] Car lights (such as high beams) have incandescent lamps ( figure 1 ) and LED lights and other types. The incandescent lamp has high power and high temperature. Its main components are the filament (usually tungsten wire) and the electrode leads (made of Dumet wire) at both ends of the tungsten wire. Dumet wire is made of iron-nickel alloy wire (nickel content 43.0 ± 0.5%) as the core wire, electrolytic copper as the coating, and borate (Na 2 B 4 o 7 ) for coating. The coefficient of thermal expansion of Dumet silk is (8-10)x10 -6 / °C. In order to fix the two Dumet wire leads and prevent short circuit problems caused by softening, bending or winding, it is necessary to fix the two Dumet wires with high temperature resistant glass,...
