Document Type and Number:
Japanese Patent JPH09509105
Kind Code:
A
Abstract:
Coated abrasives (10) are provided wherein an effective amount of a fibrous reinforcing material (12) is engulfed within an organic polymeric binder material. Sufficient binder is present such there is one or more regions of organic binder material free of fibrous reinforcing material (13), to which abrasive particles (16) are attached. Endless, seamless articles of the invention preferably include a length with parallel side edges, and at least one layer of fibrous reinforcing material engulfed within the organic polymeric binder material. The fibrous reinforcing material can be in the form of individual fibrous strands (12), a fibrous mat structure, or a combination of these. Methods for preparing the coated abrasives are also provided. One preferred method is a continuous web process wherein a fibrous reinforcing material is unwound from a roll, then engulfed in a binder precursor. Abrasive particles are applied to the still flowable binder precursor and the structure expose to curing conditions. Optional size coatings (17) and supersize coatings are applied in subsequent steps, whereafter the web is wound into a roll. This procedure advantageously eliminates the step of separately applying a traditional make coating.
