Abstract

The invention provides a porous ceramic block, a metal-matrix composite and preparation methods of the porous ceramic block and the metal-matrix composite. After organic foam covered with ceramic slurry is dried, evaporated and sintered, the porous ceramic block is obtained, wherein the organic foam is polystyrene foam plastic or polyurethane foam plastic; the ceramic slurry is prepared from ceramic powder, a binder and a solvent, the ceramic powder is aluminum oxide or / and chromic oxide, the binder is an organic binder or an inorganic binder, and the solvent is water or an organic solvent. The preparation method of the porous ceramic block is simple, holes in the ceramic block are evenly distributed, the sizes of the holes are easy to control, it is easier to prepare a metal-matrix composite wear-resistant material from the porous ceramic block, the preparation steps of the composite wear-resistant material are simplified, and distribution of ceramic in a metal matrix can be controlled more conveniently.

Description

technical field

[0001] The invention relates to the field of composite materials used in crushers, in particular to a porous ceramic block, a metal matrix composite material and a preparation method thereof. Background technique

[0002] In metallurgical mining, building materials, road construction, chemical and silicate industries, crushers are the main equipment for material crushing. With the rapid development of my country's economy, the materials that need to be processed by crushers in these industries increase geometrically every year. There are many factors that affect the crushing process, but they are all related to the performance of crushing equipment. The wear resistance of liners, hammer heads, rollers and roller teeth and other parts that are easy to wear in the crusher has a great impact on the performance of the crusher.

[0003] At present, the main problems in the development of crushers are that there are few new wear-resistant materials used, and the m...
