Title:
ABRASIVE FILM
Document Type and Number:
Japanese Patent JP3201870
Kind Code:
B2
Abstract:
PURPOSE: To eliminate the possibility of blinding at the inner peripheral portion of a roll so as to avoid variation in machining performance by laminating an abrasive layer containing spherical grains of a specific average grain size on a base, thus forming an abrasive film.
CONSTITUTION: An abrasive material having an average grain size of about 0.4 to 3μm, such as alumina, silicon carbide, diamond and zirconia, and spherical grains selected from ceramics, glass and polymer beads, are mixed with a binder resin such as a thermoplastic or thermosetting resin and the mixture is evenly dispersed in a solvent to prepare a liquid for application. The liquid for application is applied to a base such as a polyester film and dried to form an abrasive layer so as to obtain an abrasive film. The amount of spherical grains added is preferable 3 to 5wt% of the abrasive material and the thickness of the abrasive layer is preferable 10 to 20μm. The abrasive film obtained has its surface property uniformly controlled inside a roll so that variation in machinability can be avoided.
