[0029] The present invention is a method for preparing silver-based contact material with high resistance to material transfer. The preparation method is used to prepare the silver-based contact material with high resistance to material transfer of the present invention, such as figure 1 As shown, the specific steps are as follows:
[0030] Step 1. Weigh the following materials according to mass percentage: TiB with a purity greater than 99.9% and a particle size of 50nm 2 Graphene with a purity of 2% to 8%, 0.2% to 1.2% with a purity of greater than 99.9%, the balance being Ag powder with a purity of greater than 99.9% and a particle size of 72μm, and the sum of the mass percentages of the above components is 100%;
[0031] Step 2. Weigh the TiB 2 The powder and graphene are put into a planetary ball mill, the ball-to-material ratio is 10:1-40:1, the speed of the ball mill is 200-450rpm, and the ball mill is 2h-48h to obtain the initial mixed powder;
[0032] Step 3. Add the weighed ...
