METHOD FOR PRODUCING POLISHING PAD
Document Type and Number:
Japanese Patent JP2018122426
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a method for producing a polishing pad which has a base material obtained by curing a resin containing an epoxy resin excellent in polishing efficiency as a main component, or a base material obtained by impregnating and curing a resin containing an epoxy resin in a composition formed of a fiber such as a non-woven fabric, a woven fabric, a mesh, and a bristle.SOLUTION: There is provided a method for producing a polishing pad which has a base material obtained by curing a resin containing an epoxy resin as a main component or a base material obtained by impregnating and curing a resin containing an epoxy resin in a composition formed of a fiber, relatively moves the workpiece along a tool reference surface while supplying a slurry containing a polishing material between the tool reference surface and the workpiece, and polishes the workpiece, where the epoxy resin forming the base material has an epoxy equivalent of 150 to 300, a bisphenol A type or a bisphenol F type main agent containing no reactive diluent is cured with the use of a cation polymerization catalyst such as Lewis acid without using a curing agent, or when the curing agent is used, an amine-based compound having an active hydrogen equivalent (amine equivalent) of 200 to 500 is used.SELECTED DRAWING: None
