Method for preparing efficient aerated mixed powder

Abstract

The invention relates to a method for preparing efficient aerated mixed powder of an AgSnO2 wire. The method comprises the steps as follows: aluminium powder and putty powder are placed into a mixing pot and stirred to obtain mixed powder; then the mixed powder is sucked into an efficient powder-mixing machine for mixing; then the mixed powder is placed into a cold isostatic press for compression moulding; the pressed mixture is taken out and placed into a vacuum sintering furnace for vacuum sintering; the sintered mixture is placed into an extruder for extruding, and then the mixture is placed into an ultrasonic washing machine for washing filaments on the surface of the mixture; and the mixture is subjected to vacuum annealing, finally the final reactant is subjected to wire-drawing through a wire-drawing device, and a finished product with the required diameter is obtained. The method solves the problems of aluminium powder agglomeration and putty powder agglomeration as well as hardness and density of the AgSnO2; the long-term performance of the finished product is stable, and the plasticity and the performance of the material are improved.

Description

technical field [0001] The invention belongs to the field of high-efficiency aerated powder preparation, and in particular relates to an AgSnO 2 A high-efficiency air-entraining and powder-mixing preparation method for silk. Background technique [0002] Silver tin oxide material is a new type of high-tech material. At present, the performance of silver tin oxide material in China is not very ideal. Usually, the preparation methods of silver tin oxide are: 1. Using V-type machine mixing process, isostatic pressing method, ordinary sintering and extruding into wire , Carrying out the hot drawing process, the tin oxide powder of this process is seriously aggregated, the processing plasticity is poor, the electrical properties are not ideal, and the use effect is poor. 2. The three-dimensional powder mixing process is adopted. The density of the main materials of the three-dimensional powder mixing technology cannot be increased, the speed of the powder mixing equipment is too...
