摘要： This invention relates to a method for the manufacture of an abrasive material by means of a synthetic binder based on a mixture of phenolic resins. The phenolic resins employed have a great stability in storage, its curing times are at most equal to but preferably shorter than those commonly used, therefore higher production speeds or substantially smaller drying installations for the same production speed may be used. The binder contains only small quantities of free formaldehyde, phenol and especially formaldehyde are released in substantially reduced quantities to the environment even when the binder is heated to elevated temperatures, including temperatures above the processing temperature. The release of these substances is also considerably reduced when the abrasive material is subsequently used. The synthetic binder is based on an aqueous mixture of phenolic resins and optionally other additives wherein the mixture of phenolic resins comprises (I) at least one phenolic-resol and (II) at least one co-condensate of at least one monohydric phenol and at least one polyhydric phenol with formaldehyde. The molar ratio of the quantities of formaldehyde used to the sum of phenols in component (II) is within the range of from 0.6:1 to 1.5:1. An abrasive material prepared by means of said method is a further object of this invention.
