This disclosure, in general, relates to nonwoven abrasive belts including flexible butt joints and methods of making and using such belts and joints.

Nonwoven abrasive belt with flexible joint

Articles and methods regarding the making and use of low-shedding nonwoven abrasive articles, such as abrasive wheels and hand pads, that have a low shed rate and achieve a high grind ratio. The abrasive articles comprise a blend of a plurality of primary abrasive particles and a plurality of reinforcing abrasive particles that is disposed on a nonwoven web substrate. The primary abrasive particles have an average particle size equal to or larger than the average fiber diameter of the substrate fibers, and the reinforcing abrasive particles have an average particle size smaller than the average fiber diameter.

Low-shedding nonwoven abrasive articles

The present disclosure relates to abrasive articles that include abrasive aggregates of silicon carbide with a vitrified bond, and methods of making and using such abrasive articles and abrasive aggregates. In particular, the abrasive aggregates can possess a combination of beneficial properties and comprise a vitreous binder composition having a specific composition, sintering temperature, glass transition temperature, or a combination thereof.

Abrasive articles including aggregates of silicon carbide in a vitrified bond

Abrasive articles including a non-woven web of staple fibers that form a single layer that is free of any additional layers of non-woven webs of staple fibers. The abrasive articles contain abrasive particles bound to the non-woven web. The abrasive articles can be compressed abrasive articles that include a non-woven web of staple fibers, including blends of staple fibers having a first portion of fibers having a first linear density and a second portion of fibers having a second linear density.

Nonwoven abrasive article with extended life

A surface-treating article includes an organic matrix substantially engulfed by a binder that includes a reaction product of a blocked polyurethane prepolymer and a mixture of aromatic amines. The aromatic amines include polymethylene polyaniline having a functionality equal to or greater than 4.

Smear-free nonwoven composite abrasives

An abrasive article comprising a nonwoven substrate material having a top surface and a bottom surface; a woven cloth; a thermoplastic fastener; and a plurality of abrasive particles, wherein the cloth layer is adhered to the top surface of the nonwoven substrate material; wherein the thermoplastic fastener is disposed on the cloth, and wherein the plurality of abrasive particles are disposed on at least the bottom surface of the nonwoven abrasive substrate.

Nonwoven abrasive articles made by friction welding

An abrasive article includes a support, a first polymeric binder, a second polymeric binder, and abrasive particles. The support includes a plurality of nonwoven layers. A method of forming an abrasive article includes providing a support including, applying a first coating of the first polymeric binder to the support, applying superabrasive particles to the coated support, applying a layer of a second polymeric binder overlying the superabrasive particles. The method further includes compressing the support and applying heat to cure the first polymeric binder. A method of preparing a work piece includes applying a thermal spray coating to the work piece, and polishing the thermal spray coating with the abrasive article.

Nonwoven composite abrasive comprising diamond abrasive particles

A polyurethane adhesive composition, formed by combining a non-blocked urethane prepolymer and a polymeric polyol, is used for preparing a coated abrasive tool. The polyurethane adhesive composition is applied over a substrate to thereby form a polyurethane-adhesive-composition-coated substrate. Curing the polyurethane-adhesive-composition-coated substrate forms a polyurethane-adhesive-coated substrate. An abrasive material is applied over the substrate at a time selected from the group consisting of prior to, after, and simultaneously with, the application of the polyurethane adhesive composition to the substrate, to thereby form the coated abrasive tool. The coated abrasive tool preferably includes a polyurethane adhesive resin coating over the substrate, the resin coating being formed from a polymerization reaction of a non-blocked urethane prepolymer and a phenoxy resin.

Coated abrasive tools from non-blocked urethane prepolymer

An adhesive for use in coated abrasive belt joints includes a blocked isocyanate, urethane system. The blocking agent can include phenols, oximes, alcohols, caprolactam, and diethyl malonate. The adhesive can be crosslinked with amine or alcohol. A coated abrasive belt is formed by attaching a plurality of abrasive particles to a first surface of a backing layer. A size coat is deposited over the abrasive particles to form a coated abrasive. The coated abrasive is cut to form a strip having a first end and a second end. The ends of the strip are joined with an adhesive including a blocked isocyanate, urethane system.
