Description
Technical field:
The present invention relates to friction material and waste recovery utilizes technical field, particularly relate to a kind of modification regeneration and utilize type automobile brake sheet and preparation method thereof.
Background technique:
In friction material production process, and all can produce more abrasive dust the like waste processing abrasives, in boring procedure, due to these wastes, to have dust large; May have in impurity enters; Composition is unstable; Waste adds the rear degradation of formula; Waste kind difference is difficult to the defects such as utilization, so how to dispose these waste products and waste, is a unmanageable problem.At present, only have small part fractional material factory to utilize a small amount of waste, narrow limitation of but not opening all the time, also fail to solve the problem of its environmental pollution.
Summary of the invention:
The object of the invention is to the defect overcoming prior art, provide a kind of modification regeneration to utilize type automobile brake sheet and preparation method thereof.Obtained brake block has brakes sensitive, little, that the life-span is long advantage of wearing and tearing.
For achieving the above object, the technical solution used in the present invention is:
A kind of modification regeneration utilizes type automobile brake sheet and preparation method thereof, and it is characterized in that, each raw material components and weight proportion are:
