METHOD FOR STRONGLY JOINING POLYURETHANE SHELL TO METAL SURFACE OF SHAFT Russian patent published in 2003 - IPC

Abstract RU 2199567 C2

FIELD: polymer materials. SUBSTANCE: invention relates to manufacturing metal shafts leaned peripherally with wear-resistant polyurethane shell, For that, preliminarily prepared metal surface of shaft is first covered with adhesive underlayer 50-150 mcm thick containing fine iron powder with particle size 50-150 mcm, constituents of this underlayer being taken at following ratios: diamine hardener/diluent 1:1; epoxide resin/diamine hardener solution between 1:1 and 1.2:1; epoxide resin/diamine hardener solution/iron powder between 1:1:2 and 1.2:1:3. EFFECT: increased adhesion strength. 2 tbl
