Abstract
The invention relates to the field of processing of automobile accessories, particularly an automobile clutch damping fin and a processing method thereof. The clutch damping fin comprises natural rubber, styrene-butadiene rubber, phenol formaldehyde resin, brucite, anti-aging agent, accelerator, carbon black, sulfur powder, barium sulfate, feldspar powder and tar. The processing method comprises the following steps: primary mixing, secondary mixing, tertiary mixing, discharging, compounding, die cutting and vulcanizing. Compared with the prior art, the invention has the advantages of easily purchased raw materials, high recycling rate, stable product quality and environmental protection.
Description
Technical field
The present invention relates to a kind of auto parts machinery manufacture field, particularly a kind of automobile clutch damping fin and working method thereof.
Technical background
Before and after automobile clutch, all damping fin is housed between damping disk(-isc), certain relative movement is had between damping fin and front and back damping disk(-isc), when there is twisting vibration in power train, friction resistance must work done, the Conversion of energy of twisting vibration is that heat energy is consumed, decrease the amplitude of twisting vibration, and make vibration decay quickly.Though the little effect of clutch damping fin is large, if there is no deoscillator damping vibrations, impact meeting last very long, increase sliding wear degree, reduce the work-ing life of clutch coupling.
The production of current clutch damping fin is all by roller refining, slice, sulfuration, then die-cutly completes.Due to different model clutch coupling needed for the thickness of damping fin, size, shape all not identical, the leftover bits after therefore die-cut are more.And in production process, inevitably produce some underproof defect wares, these defect wares are the same with leftover bits, cannot again recycle after over cure, usually can only be processed by the way of burying or burning, waste resource is not said, also impacts the environment gone from bad to worse.Simultaneously the existence of defect ware and leftover bits, makes raw-material utilization ratio to improve further, thus causes cost increase, makes product lose competitive edge in price.
Summary of the invention
Object of the present invention for solving this technical problem, provides a kind of utilization rate of raw materials almost can approach the clutch damping fin production technique of the environmental protection of 99% just.
For this reason, technical scheme provided by the invention is: clutch damping fin, and its composition comprises natural rubber, styrene-butadiene rubber(SBR), resol, brucite, anti-aging agent, promotor, carbon black, SULPHUR POWDER, barium sulfate, Feldspar Powder, tar.
As preferably, the content of described each composition, is by weight:
As preferred further again, the content of described each composition, is by weight:
As preferred further again, the model of natural rubber is 3#, and the model of described styrene-butadiene rubber(SBR) is 1502#, and the model of described resol is 2123#, and described anti-aging agent is anti-aging agent RD.
As preferred further again, described promotor is the mixture of captax or vulkacit D or captax and vulkacit D.
As preferred further again, in the mixture of described captax and vulkacit D, captax weight is divided into 1.8 parts, and vulkacit D weight is divided into 1.5 parts.
Process the method for this clutch damping fin, comprise the steps:
A, a refining: by the mixing roll refining on rubber mixing machine of natural rubber, styrene-butadiene rubber(SBR), anti-aging agent, promotor;
B, two refinings: on the basis of a refining, add the mixing roll refining again on rubber mixing machine of resol, carbon black, SULPHUR POWDER, barium sulfate again;
C, three refinings: on the basis of two refinings, add the mixing roll refining again on rubber mixing machine of brucite, Feldspar Powder, tar again; Now also remaining for die-cut operation leftover bits and defect ware can be mixed together roller refining;
D, slice: the roll spacing adjusting rubber mixing machine as required, slice;
E, compound: determine whether that the sheet material needing slice operation to obtain carries out two-layer above compound as required;
F, die-cut: Punching Technology becomes different sizes, the work in-process of shape as required;
G, sulfuration: the work in-process of die-cut operation are put into vulcanizing apparatus and carries out sulfuration, namely obtain finished product.
As preferred further, the curing temperature in described vulcanization process is 164 DEG C, and pressure is 4kg/cm
2.
The present invention compared with prior art has that raw material is easily purchased, repeating utilization factor is high, constant product quality, environmental protection advantage.
