Method of making abrasive articles |
摘要 |
A method of making abrasive articles which includes the steps of sandwiching and adhering abrasive particles between two sheets of fiber where the particles have a major cross-section dimension greater than the thickness of the sheets into resultant second sheets. The resultant second sheets are then adhered together by lamination under pressure so that the abrasive particles of a second sheet enter the interstices between the abrasive particles of adjacent other second sheets to form an interlocking bond and increase the tensile strength. The sheets are preferably cut from a processed strip prior to lamination. Prior to lamination the second sheets may be coated with one or both of a liquid rubber and a thermosetting resin. If resin is used the stack is heated as it is pressure laminated. The application of rubber and resin may be in the alternative. The application of rubber imparts flexibility while the resin upon curing imparts hardness. There may be a compromise between the two to reach a desired degree of flexibility or hardness.
