Technical Field
The invention relates to the field of grinding block materials, in particular to a metal-based terrace grinding block material for concrete grinding.
Background
Concrete floors are generally classified into five categories, namely, ultra-soft, medium-hard, hard and ultra-hard, according to the hardness and strength of the concrete floor. A terrace grinding block manufacturer prepares a corresponding terrace grinding block according to the ground type, so that the terrace grinding block is more in type and not strong in universality. In addition, as the price, labor cost, etc. of metal powder increase, cheaper matrix metal powder is sought.
For example, the matrix material for the diamond grinding tool disclosed in Chinese patent CN201610776057.X is prepared from the following raw materials in parts by weight: 45-56 parts of copper-iron alloy powder; 12-18 parts of copper-tin alloy powder; 24-36 parts of copper-coated graphite powder; 3.5-4.5 parts of ferrosilicon powder; for another example, a diamond grinding tool disclosed in chinese patent No. cn200610135222.x, the soft matrix material thereof includes the following components by weight: 12-20% of cobalt-iron alloy, 75-85% of bronze powder, 2-6% of zinc powder and 1-7% of filler. The preparation of the matrix material in the patent mostly uses copper as a main component, and the price of copper in the market is far higher than that of iron, so that the use of a large amount of copper as the main component of the matrix material greatly increases the production cost price, and particularly, the use of copper in the matrix material disclosed in the patent CN200610135222.X accounts for more than 75 percent, so that the production cost is directly increased, and the production cost is higher.
In view of the above, the present inventors have studied the above problems and have proposed a metal-based floor grinding block material for concrete grinding, which has a wide versatility and a low cost.

Preferably, the diamond grain size is 25# -120 #.
More preferably, the diamond grain size is 25# -40 #.
Preferably, the diamond grain size is 60# -80 #.
Preferably, the diamond grain size is 100# -120 #.
The technical scheme of the invention has the following beneficial effects:
the used matrix material, namely the bonding agent has extremely high iron content which is over 50 percent, and the price of the iron powder in the market is very low, and the price of the reduced iron powder is 7 times lower than that of the electrolytic copper powder, so that the aim of reducing the product cost can be achieved;
second, Fe has better affinity with the diamond, because iron content is high in the matrix material, consequently, the interface cohesion of metal matrix body and diamond strengthens, and the matrix strengthens the power of gripping of diamond, and the reduction abrasive brick that can be fine drops of diamond in the use, very big promotion the utilization ratio of diamond, prolonged the life of abrasive brick, improvement product price/performance ratio. In addition, due to the improvement of the utilization rate of the diamonds, the usage of the diamonds is reduced when the grinding block is ensured to have a certain level of sharpness, and the effect of reducing the product cost is achieved.
The matrix material with high iron content is used, so that the product cost can be well reduced, the using effect is better, and the cost performance is higher, but the matrix contains more than 50% of iron, so that the abrasion resistance of the matrix is very high, diamond in the matrix is difficult to blade, and the sharpness of the concrete grinding block is poor, therefore, trace aluminum-silicon pre-alloy powder (the content of Si is 12.6-20%) is added into the matrix, the structure of the aluminum-silicon pre-alloy powder consists of beta (Si) + eutectic (alpha (Al) + beta (Si)), the matrix structure can be loosened, the abrasion resistance of the matrix is reduced, the abrasion resistance of a high-iron matrix is improved, the blade of the diamond is improved, and the sharpness of the concrete terrace grinding block is improved.
