Abstract

The invention discloses a metal-based floor grinding block material for concrete grinding, which belongs to the field of grinding block materials, and includes abrasives and a bonding agent, and the bonding agent includes system materials and weakening materials; the components and mass percentages: the abrasives include: diamond 6 ‑30%; system materials include: Fe, 50‑86%, Cu, 6‑13%, Ni, 1‑5%, Sn, 0.5‑2%; weakening materials include: aluminum-silicon pre-alloyed powder, 0.5‑4% . The beneficial effect of the invention is that the prepared metal-base floor grinding block material for concrete grinding not only has good sharpness and wide versatility, but also has low cost and high cost performance.

Description

technical field [0001] The invention relates to the field of grinding block materials, in particular to a metal base floor grinding block material for concrete grinding. Background technique [0002] According to the hardness and strength of the concrete floor, the concrete floor is usually divided into five categories, namely super soft, soft, medium hard, hard, and super hard. Floor grinding block manufacturers prepare corresponding floor grinding blocks according to the type of ground, which leads to many types of floor grinding blocks and poor versatility. In addition, as the price of metal powder and labor costs increase, it is necessary to look for cheaper matrix metal powder. [0003] For example, a matrix material for diamond abrasive tools disclosed in Chinese patent CN201610776057.X is made of the following raw materials in parts by weight: 45-56 parts of copper-iron alloy powder; 12-18 parts of copper-tin alloy powder; copper-clad graphite powder 24-36 parts; 3....
