Abstract
The invention discloses a modified-and-recycled type vehicle brake pad and a production method thereof, and relates to the technical field of recycle of friction materials and wastes. The components of the modified-and-recycled type vehicle brake pad include, by weight, 10-20% of binder, 15-30% of reinforced fibers, 30-70% of recyclable materials, 1-10% of friction increasing agent, 5-30% of lubricant and 5-12% of fillings. The recyclable materials are the wastes generated during production of the friction materials. Various wastes of the friction materials are smashed and sieved to enable the fineness of the wastes to reach within 120 meshes, polymer modified layers are formed on the surface of powder of the wastes by a stem grafting method, and dispersion stability of the wastes in macromolecule matrixes is improved through spatial steric effect of the modified layer, so that organic composite materials with high dispersion and low filling performance can be produced. The wastes are utilized, emission of the wastes is greatly reduced, pollution of the wastes to environment is reduced, energy consumption is reduced, product performance is not degraded while product cost is greatly reduced, and some performance can be improved.
Description
Technical field:
The present invention relates to friction material and waste recovery is utilized technical field, relate in particular to a kind of modification regeneration and utilize type automobile brake sheet and preparation method thereof.
Background technique:
In the friction material production process, and abrasives is being processed, all can produced more abrasive dust the like waste in the boring procedure, because that these wastes have a dust is big; May have in impurity goes into; The composition instability; Waste adds prescription back degradation; Waste kind difference is difficult to defectives such as utilization, so how to dispose these waste products and waste, is a unmanageable problem.At present, have only the small part fractional material factory to utilize a spot of waste, the narrow limitation of but not opening all the time also fails to solve its environmental pollution problems.
Summary of the invention:
The objective of the invention is to overcome the defective of prior art, provide a kind of modification regeneration to utilize type automobile brake sheet and preparation method thereof.The brake block that makes has the advantage that braking is sensitive, wearing and tearing are little, the life-span is long.
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, it is characterized in that, each raw material components and weight proportion are:
Bond 10-20; Reinforcing fiber 15-30; Regeneration material 30-70; Increase the agent 1-10 that rubs; Oiling agent 5-30; Filler 5-12;
Wherein, described regeneration material is the waste that produces in the friction material production process, various types of friction material wastes are carried out crushing screening, its fineness is reached in 120 orders, adopt the grafting method to form polymer-modified layer at the waste powder surface, utilize the space steric effect of decorative layer to improve its dispersion stabilization in macromolecule matrix, thereby the low organic composite material of filling of preparation high dispersive, after the graft modification of waste powder on graft molecular chain and the waste powder surface functional group bonding has taken place, add certain water soluble phenol resin then, prepare the regeneration material by adding the water comminution granulation, drying is sieved again, makes the regeneration material that is the modification primordial condition.
Described Bond is phenolic resin or rubber.
Described reinforcing fiber is man-made mineral fiber, natural mineral fiber, ceramic fiber, glass fibre or organic fiber or its mixture arbitrarily.
It is described that to increase the agent that rubs be aluminium oxide, bauxite, chromite or zircon.

A kind of modification regeneration utilizes the preparation method of type automobile brake sheet, it is characterized in that step is:
(1) is placed in the high speed mixer after each raw material components is disposed in proportion and mixes, make mixture;
(2) mixture that makes is placed mould heating, pressurization, moulding;
(3) with the brake block after the moulding after Overheating Treatment, mill processing, boring, get product.
The waste material that produces in the recycling production process of the present invention can belong to environment reduction of discharging, resources conservation category.
Described heat treatment only is conventional treatment; Mill processing is exactly to press the inside and outside arc end face of figure paper conversion etc., and holing by the figure paper size at last gets product.
Testing result of the present invention all meets standard by GB5763-2008 friction and every index performance, wherein density about 2 ±, hardness HRM60 ±, impact 〉=0.3, weight wearing and tearing 5% ±.
The present invention is directed to the various wastes that produce in the friction material production process studies.Waste has multiple: the dust that the slitter edge bar of compacted products, various waste product sheet, mill processing produce, sawing bar and the material that is scattered of trifling, the size transformation of the way that produces during boring.Study the method for removing impurity in the various wastes, studied the difference between them.At the problem of waste utilization, tested multiple processing method, successfully developed the approach of waste utilization through the regeneration material.As successfully having developed the novel comminution granulation without solvent in the method for the processing regenerated utilization material of the present invention.The particle that all size does not wait forms the discontinuous phase structure in brake block, obtained the well behaved effect of brake block.Along with the further investigation to all raw materials of friction material, inquired into the rule of interchangeability between them, inquired into that the processing and utilization material is bonding to matrix, the influence of compacting and accumulation, understanding is progressively deepened like this, broken through some traditional circles, strengthened the input amount of regeneration material, by processing regenerated utilization material and the abundant reasonably combined effect of bringing into play modified synergic of other raw material, finally make the high quality car brake block, solved the difficult problem of waste utilization product performance variation.Finished the task that modification utilizes type braking automobile slice prescription and technology.This measure is the example of the recycling economy research and development of brake block production, is the example of brake block resources of production saving, meets national industrial policies fully.
The present invention utilizes the various wastes that produce in the friction material production process to be processed into the regeneration material, with the regeneration material as the main raw material of friction material made again modification contain the regeneration material many, the high quality car brake block, reached the minimizing disposal of pollutants, waste utilization, many purposes such as reduce cost.The present invention can be used to produce drum-type brake pad, more can be used to produce disc brake pad.There is the granule that differs in size of discontinuous phase in brake block matrix of the present invention, presents good modified effect.
The invention has the beneficial effects as follows:
The present invention has utilized waste, has significantly reduced discharging wastes, has reduced the pollution of waste to environment, has reduced the consumption of resource, greatly reduces product cost and does not reduce product performance, and some performance can also improve, and achieves many things at one stroke.
