Abstract

The invention discloses a rubber and resin compound binding agent for a grinding wheel and a preparation method of the rubber and resin compound binding agent. The preparation method comprises the following steps: (1) placing bismaleimide, poly(ether-ether-ketone) and titanium dioxide in a ball mill, and carrying out mixing uniformly to obtain a primary material; (2) placing butadiene styrene rubber into an internal mixer for plastication, starting discharge when the temperature is 160 DEG C or above, and leaving the discharged material to be naturally cooled; (3) mixing the cooled material, polyamine-imide and chromium oxide, placing the mixture into the internal mixer to be mixed, then adding the primary material, discharging the obtained material after mixing, and leaving the obtained material to be naturally cooled; and (4) placing the naturally cooled material, ferrous disulfide and caprolactam into a mixer to be mixed for 20-30 min, and sieving the mixture with a screen of 25-35 meshes to obtain the rubber and resin compound binding agent for the grinding wheel. The rubber and resin compound binding agent and the preparation method thereof have the benefits that rubber and resin are organically combined to produce the compound binding agent which has the advantages of both rubber and resin and avoids the disadvantages of both rubber and resin, and the rubber and resin compound binding agent is excellent in heat resistance and corrosion resistance, large in air porosity, easy in outline keeping, high in strength and high in elasticity.

Description

technical field [0001] The invention relates to a bonding agent for a grinding wheel, in particular to a bonding agent for a rubber-resin composite grinding wheel. Background technique [0002] Grinding wheel, also known as bonded abrasive, is a bonded abrasive with a certain strength that consolidates ordinary abrasives into a certain shape (mostly round, with a through hole in the center) by a bond. It is generally composed of abrasives, binders and pores. These three parts are often called the three elements of bonded abrasives. According to different classifications of bonds, the common ones are ceramic (bond) grinding wheels, resin (bond) grinding wheels, and rubber (bond) grinding wheels. Grinding wheel is the most widely used type of grinding tool. It rotates at high speed when used, and can be used for rough grinding, semi-finishing and Fine grinding as well as grooving and parting off etc. The substance used to bond the abrasive in the grinding wheel is called a ...
