Surface treating articles and method of making same
First Claim
1. A surface treating article, comprising:
- a rotatable core having an outer surface;
a plurality of surface treating segments, each of said segments having a first portion adjacent said outer surface of said core and second portions opposite said first portions, said second portions collectively arranged to form a working surface of the surface treating article; and
a cured expanded adhesive composition bonding said first portions of said surface treating segments to said outer surface of said core, wherein, said cured expanded adhesive composition comprises the reaction product of;
a) an organic epoxide compound having an epoxide functionality of at least 1,b) an epoxide hardener,c) a film-forming material selected from the group consisting of butadiene/nitrile rubbers, carboxylated butadiene/nitrile rubbers, carboxy-terminated butadiene/nitrile rubbers, amine-terminated butadiene/nitrile rubbers, polyether diamines, polyhydroxyethers, graft polymers having a rubbery polyacrylate core with a polyacrylate or polymethacrylate shell, polyvinyl acetals and mixtures thereof, andd) a foaming agent selected from the group consisting of azobisisobutyronitriles, azodicarbonamides, carbazides, hydrazides, non-azo chemical blowing agents based on sodium borohydride or sodium bicarbonate/citric acid, dinitrosopentamethylenetetramines, liquefied gases encapsulated in a polymeric thermoplastic shell, and mixtures of the foregoing materials.

Abstract
Surface treating articles and methods for the manufacture of such articles are provided. The articles of the invention comprise a rotatable core; a plurality of surface treating segments, the segments having first ends adjacent the core and second ends opposite the first ends; and a cured, expanded adhesive composition bonding the surface treating segment to the core, the adhesive composition comprising (a) an organic epoxide compound having an epoxide functionality of at least 1, (b) an epoxide hardener, (c) a film-forming material, and (d) a foaming agent; wherein the expanded adhesive provides a substantially continuous bond area extending from the core into and around the first end of the segments. The method for the manufacture of the articles comprises applying the foregoing adhesive to the core, applying the surface treating segments to the core by positioning the first ends of the segments adjacent the core and in contact with the adhesive; expanding the adhesive into the first ends of the surface treating segments; and hardening the adhesive to form the surface treating article.
