Abstract

The invention discloses a preparation method of a metal framework reinforced ceramic-based composite binding agent. The method comprises the following steps: firstly, low-temperature ceramic binding agent powder is uniformly mixed with kaolin, carboxymethyl cellulose, silica sol, polyethyleneimine and octanol, and the mixture is put into a ball mill for ball milling; secondly, powder obtained through ball milling and deionized water are prepared into slurry according to a certain proportion; and finally, the metal framework is placed in a mold, then the obtained slurry is poured into the mold, and after the slurry is solidified and formed, the metal framework reinforced ceramic-based composite binding agent can be obtained. Compared with a traditional metal powder reinforced ceramic binding agent, the composite binding agent obtained through the method has the good mechanical property and can be used as a new-generation superhard grinding wheel binding agent.

Description

technical field [0001] The patent of the present invention relates to the field of metal-ceramic composite binders, specifically the preparation method of making metal skeletons from metal powder and reinforcing ceramic-based composite binders with metal skeletons, which are mainly used in the fields of grinding and polishing. Background technique [0002] The development of materials affects the development of science and technology, and the development of new materials has a huge impact on the development of all sectors of society. Therefore, how to carry out research on new materials is a key issue at present. The rapid development of the scientific level now makes the industry put forward more stringent requirements for the performance of materials, such as higher mechanical strength, higher Young's modulus, higher thermal conductivity, higher heat resistance and higher coefficient of friction and wear, etc. Nowadays, traditional single-phase materials can no longer me...
