Abstract

가. 청구범위에 기재된 발명이 속한 기술분야end. The technical field to which the invention described in the claims belongs

고로 수재슬래그를 이용한 마찰재 제조방법.Method for manufacturing friction material using blast furnace slag.

나. 그 발명이 해결하려고 하는 기술과제I. The technical problem that the invention is trying to solve

종래 마찰재 보강재인 석면대체 원료로 암면섬유와 유리섬유가 사용되는데 이는 제조가 곤란하고, 고가인 폐단을 갖는 것임.Rock wool and glass fibers are used as raw materials for replacing asbestos, which is a conventional friction reinforcement material, which is difficult to manufacture and has an expensive closed end.

다. 그 발명의 해결방법의 요지All. Summary of the Solution of the Invention

본 발명은 암면섬유와 유리섬유를 대체하는 마찰재 보강제로써 고로 수쇄슬러그를 이용하므로써 저렴하고, 환경오염의 우려가 없으며, 자원의고부가가치화 할 수 있는 것임.The present invention is inexpensive by using the blast furnace slug slug as a friction material reinforcing agent to replace rock wool fibers and glass fibers, there is no fear of environmental pollution, it is possible to add a high value of resources.

라. 발명의 중요한 용도la. Important uses of the invention
