Description
Technical field
The invention belongs to field of rubber technology, and in particular to a kind of heat-resistant anticorrosive rubber pad formula and preparation method thereof.
Background technology
With the development of national economy, rubber military project, it is civilian in purposes it is more and more extensive, performance requirement also by
Simple sealing is increased to high temperature resistant, media-resistant oil, anticorrosion, anti-aging, warping strength to wait requirement, and has on this basis deeper
The raising of level.For example the amount of present family car is stepping up, rubber and plastic sizing material is in purposes automobile sealed, on interior trim
More and more extensive, automobile high-performance, lightweight, high performance development trend also require rubber-plastics material to higher level direction
Development.Fluorubber is widely used in automobile hair as a kind of high heat resistance, hypotonicity energy and excellent medium-resistance
The positions such as motivation vehicle bridge, transmission seal.But Railway Project of the fluorubber as sealing article puzzlement user, 1 mixed refining process are relatively tired
It is difficult；Permanently denaturation is higher for the compression of 2 vulcanization rubber, directly results in product product height dimension when higher temperature uses for a long time
There is difference；The tearing strength of 3 vulcanization rubber standard samples is relatively low, directly results in product product when vulcanizing depanning and is easily torn
It splits.To improve the quality of product and increasing the service life of product, problem above is badly in need of solving.
The content of the invention
It is an object of the invention to provide a kind of heat-resistant anticorrosive rubber pad formulas and preparation method thereof.
The technical scheme is that：A kind of heat-resistant anticorrosive rubber pad formula includes the formula of following components by weight percent：
90~100 parts of fluorubber, 0~10 part of silicon rubber, 5~10 parts of magnesia, 5~10 parts of calcium hydroxide, processing aid 3
~5 parts, 30~50 parts of reinforcing agent, 2~4 parts of bisphenol AF, 5~8 parts of vinyl silicone oil, benzyltriphenylphosphonium chloride BPP 0.5~
1.5 parts, vulcanizing agent is 250.2~1 parts double.
Preferably fluorubber is Mooney viscosityFor 120~150；Fluorubber is divided into high Mooney viscosity and low Mooney
Viscosity, for making the fluorubber of rubber pad as du pont company's production in the present invention, the fluorubber of this Mooney section has higher
Intensity, while with silicon rubber and with can have preferable compression set.
Preferred processing aid palm wax, Rhein dissipate at least one of 54, and palm wax and Rhein dissipate 54 as inner pattern releasing agent applicable
The processing performance of rubber compound can not only be improved improves the release property of vulcanizate simultaneously so that vulcanizate has the good demoulding
Property
Preferred reinforcing agent is carbon black N990, ultra-fine barium sulfate, wollastonite are used in combination, carbon black N990 have grain diameter compared with
Greatly, it is preferable with fluorubber, silicon rubber Tuberculous；Wherein barium sulfate, wollastonite can not only reduce formula cost simultaneously it is inorganic
The addition of filler can assign the stronger media-resistant of rubber, antiseptic property.
The amount ratio of the bisphenol AF and benzyltriphenylphosphonium chloride BPP are 4:1.
A kind of processing method of heat-resistant anticorrosive rubber pad formula, the mixing of the rubber are divided into three steps：
A raw rubbers are plasticated, and fluorubber is plasticated 1~2 minute on a mill, during raw rubber of plasticating silicon rubber in batches
It plasticates in secondary addition open mill.
The mixing of b reinforcing agents and processing aid, operation oil is mixed uniform reinforcing agent, processing aid, operation oil two batches
It is secondary to add in the raw rubber plasticated, glue is repeatedly tapped rubber and turns in the process, mixing time is 1~2 minute；The glue being kneaded claims
For one section of rubber compound, then one section of rubber compound is carried out thin 5~10 times logical.
The thin one section of rubber compound having friendly relations of c adds in bisphenol AF, benzyltriphenylphosphonium chloride BPP and vulcanizing agent double 25.
Beneficial effects of the present invention are：The vulcanizate of this rubber compounding has the permanent denaturation performance of good compression, rubber
In process due to the use of in-lubricant, process not easy mold release in roll banding sulfidation；Vulcanize rubber tool simultaneously
There is good physical synthesis performance, the higher use formula of sexual valence is provided in the processing vulcanization of rubber slab.
