Abstract

The invention discloses a micro powder prepolymer formula, which is prepared from the following ingredients including 30 to 70 percent of grinding materials, 0.1 to 3.5 percent of auxiliary agents, 8to 45 percent of filling materials and 25 to 65 percent of adhesive water solution. Small-particle micro powder can be combined through bonding agents to become a larger micro powder prepolymer. In the grinding process of the prepolymer, the large-area multi-point contact is realized; the big particle high-speed grinding characteristics are realized; high grinding speed is realized; in addition, the prepolymer can gradually release fine and crushed ground materials in the grinding process; the restoration and polishing effects are achieved; the durable and stable cutting force is realized; meanwhile, the fine grinding surface can also be obtained. In addition, the roasting process can be regulated to obtain a smooth surface and a rough surface; the prepolymers with different combination force can also be obtained; the prepolymer is applied to the preparation of grinding liquid, coating milling tools and concretion milling tools; the high-speed and high-flatness surface processing can be realized.

Description

technical field [0001] The invention relates to the technical field of micropowder prepolymer, in particular to a micropowder prepolymer formulation and a preparation method thereof. Background technique [0002] During the use of traditional abrasives, there is a contradiction between grinding efficiency and grinding effect. Large-grained abrasives have a high grinding rate but will cause large scratches on the surface of the workpiece to be processed. Small-grained abrasives can be processed better. Superficial, but it takes a long time to work and affects efficiency. How to make grinding achieve fast and good processing results can be improved by adding additives, such as adding lubricants to reduce the scratching of large particles on the surface of the workpiece, adding dispersants or other surfactants to improve the grinding of small particles Force, etc., but these can be attributed to the improvement of the formula, which is helpful to fluid abrasives, but has certa...
