Embodiment 1

[0035] Example 1 (exploring the relationship between the addition of thermally expandable resin hollow microspheres and the polishing effect)

[0036] Explanation: The proportion of binder and abrasive in this formula is determined by mixing the binder and abrasive in different proportions and making splines for curing, then testing the mechanical performance indicators such as elastic modulus, tensile strength, elongation at break, etc. It is determined by screening out a large number of experimental data.

Abstract

The invention discloses a preparation method for a grinding wheel containing abrasive and thermal-expansion resin hollow microspheres. The preparation method includes the following steps: the abrasive, the thermal-expansion resin hollow microspheres and binder are mixed and uniformly stirred; the material is uniformly paved in a mould cavity; and the material is pressed to be shaped for two times by a hydraulic oil press.

Description

technical field [0001] The invention relates to a preparation method of a grinding wheel containing abrasive materials and thermally expandable resin hollow microspheres, belonging to the field of abrasive tools. Background technique [0002] Various polishing and grinding tools currently produced have the following defects: compact structure, poor heat dissipation, such as resin grinding wheels (due to hydraulic molding, compact structure). [0003] General resin-bonded grinding wheels (bonded abrasives) are mainly made of abrasives and resin binders after mixing, molding, and heating and hardening. The use of this type of grinding wheel has problems such as the need for large cutting forces and serious heating of the workpiece. defect. [0004] The pores in the large porous grinding wheel (bonded abrasive) are generally filled with fillers (such as walnut shells, refined naphthalene, etc.) that can be burned (ie carbonized) at temperatures above 130 degrees during hardeni...
