Description
Technical field
The invention belongs to coated abrasive tool field, be specially a kind of novel paper cloth composite base material coated abrasive tool abrasive band preparation method.
Background technology
The general manufacture method of current coated abrasive tool for carry out upper base glue on paper or cloth, plant sand, upper glue again, solidification, flexible, divide end of volume (EOV), it is good that stationery coated abrasive tool product has flatness, the little distortion that is not easily stretched of percentage elongation, but there is the low limitation of intensity in it, be not suitable for high load capacity abrasive band in making, cloth series products has higher intensity, many (see contrast tables 1) that percentage elongation is larger than paper, the phenomenon that there will be the distortion that is stretched mid-term is used in abrasive band, secondly cloth series products can not show a candle to paper product in the flatness of back of the body base, easily cut is produced when grinding, the advantage that the invention reside in conjunction with cloth and paper two aspect makes abrasive band by after cloth and paper compound.
With E type paper (250g/ ㎡) citing and a fabricbase properties of product contrast table 1
