Abstract
The invention discloses a kind of rubber detent band and preparation method thereof, including the thick ethylene propylene diene rubber basic unit of abrasive rubber top layer thick 3mm, 0.75mm thick modified butyl rubber layer, 1mm thick butyronitrile base rubber layer, 1.5mm thick microcellular elastomeric urethane layer, 0.75mm thick polyurethane rubber layer, 2.5mm, every layer of rubber layer bottom is provided with glass fiber mesh enhancement layer, and the surface on abrasive rubber top layer is staggeredly equipped with some strip grooves；Preparation process includes：Abrasive rubber top layer mould, cast abrasive rubber top layer is made simultaneously to be stripped, stack each rubber layer and fiber web layer alignment, feeding vulcanizer is vulcanized, the rubber strip after vulcanization is cut, deburring, block after, wind and pack.The strip groove that the present invention is staggered using a variety of rubber layers of multilayer, web composite construction and top layer, can increase the service life, and lift braking effect, absorb vibrations and noise.
Description
Technical field
The present invention relates to braking clothing arts, more particularly to a kind of rubber detent band and preparation method thereof.
Background technology
At present, in lifting, the operation of transmission machinery, slow down, Brake stop is brought using general abrasive rubber and reached
Purpose.Conventional brake band or non-environmental protection type product.One is the rubber detent band used, due to substantially using common rubber
Glue is made, and its characteristic is no matter continuously to be braked under any velocity conditions, and rubber strip is warming up to more than 120 DEG C due to friction
When, rubber strip modification, coefficient of friction are decreased obviously, abrasion aggravation, met water skidding, are caused the potential safety hazard of brake failure.Secondly
It is to use asbestos rubber brake band, it can reach the purpose of braking deceleration.But, due to containing asbestos, produced during friction catch
Crude asbestos dust and pollute environment.The third is the rubber strip used at this stage is typically the product of individual layer, simple function.
The content of the invention
In place of in view of the shortcomings of the prior art, it is an object of the invention to provide a kind of rubber detent band and its preparation
Method, can significantly lift the braking ability and service life of rubber detent band.
The purpose of the present invention is achieved through the following technical solutions：
A kind of rubber detent band, including abrasive rubber top layer, modified butyl rubber layer, butyronitrile base rubber layer, microvoid polyurethane rubber
Glue-line, polyurethane rubber layer and ethylene propylene diene rubber basic unit, every layer of rubber layer bottom is provided with web enhancement layer, described
The surface on abrasive rubber top layer is staggeredly equipped with some strip grooves.
In order to preferably realize the present invention, the abrasive rubber skin depth is 2.5~3.5mm, the modified butyl rubber
Bondline thickness is that 0.5~1mm, the butyronitrile base rubber layer thickness are 0.5~1.5mm, the microcellular elastomeric urethane thickness degree
It is that 0.5~1mm, the ethylene propylene diene rubber groundwork thickness are 2~3mm for 1~2mm, the polyurethane rubber thickness degree.
Further, the web enhancement layer is metallic fiber grid, carbon fiber grid, glass fibre grid
Or one kind in organic fiber grid.
A kind of preparation method for producing above-mentioned rubber detent band, comprises the following steps：
Step.1, making abrasive rubber top layer mould；
Step.2, cast abrasive rubber top layer are simultaneously stripped；
Step.3, according to said sequence by each rubber layer and fiber web layer alignment stack, feeding vulcanizer vulcanized；
Step.4, the rubber strip after vulcanization cut, deburring, block after, winding packaging.
Further, the abrasive rubber top layer raw material is：Polyurethane rubber 40%wt~60%wt, dibutyl ester 10%wt~
20%wt, ethylene propylene diene rubber 5%wt~15%wt, cumyl peroxide 1%wt~5%wt, Hinered phenols antioxidant 3%wt~5%
