Abstract
The invention discloses a kind of radiation resistant rubber diaphragms, including septum body and the braiding layer for being interspersed in the septum body；The braiding layer is the three-dimensional cage structure as made of fibrage, and the three-dimensional cage structure is formed by stacking by multiple steric configuration units, and the fiber is the functional fiber with radiation shield performance；The septum body includes following components by mass parts: 50~100 parts of rubber, 15~40 parts of screener, 2~5 parts of auxiliary agent, 2~6 parts of antiager, 2~20 parts of vulcanizing agent.The stereo weaving structure that the application uses, the stereochemical structure unit of composition, since fiber sheet is as shielding material, it being capable of effective radiation-screening, simultaneously because fiber is configured to the cage structure of 3 D stereo in septum body, the structure can effectively prevent the radiation sprawling of some reflections of radiation, secondary reflection and scattering, and 3 D stereo braiding layer can greatly improve the radiation resistance of diaphragm of rubber, while can also effectively improve the fatigue performance of diaphragm.
Description
Technical field
The present invention relates to rubber product fields, and in particular to a kind of radiation resistant rubber diaphragm and preparation method thereof.
Background technique
Diaphragm of rubber is used to automate the pneumatic actuator of pipe valve, is pressurized by chamber inflated, is pushed by diaphragm
Connecting rod provides constant drive for valve.It is generally used for that the degree of automation demand is higher or people using the valve of diaphragm of rubber
The pipe-line system in region that member can not reach, it is advantageous that making that high reliablity, plyability are good, and long working life is at low cost.Its
This diaphragm of rubber is largely used in the cooling system circuit of middle nuclear power station, within the scope of nuclear island region or nearly nuclear island, these
Diaphragm of rubber for a long time by radiation effect, perform poor by the service life, is short of stability, if burst failure, will cause heavy losses.
What is used at present in the nuclear power diaphragm prior art is still to ensure safety, state by reducing the replacement cycle using conventional separator
It inside also has been reported that, the anti-radiation performance that radiation shield filler improves diaphragm sizing material, reference are added by formula adjustment for certain company
A kind of endurance irradiation diaphragm sizing material of CN108239346A and preparation method thereof.But this diaphragm sizing material radiation resistance has
Limit.
Current diaphragm of rubber most absolutely on the market does not have the function of Flouride-resistani acid phesphatase, and a small number of Flouride-resistani acid phesphatase diaphragm of rubber only exist
The formula design phase improves, and promotes effect and is not obvious, and due to the addition of a large amount of function of shielding filler, causes original
There is diaphragm of rubber mechanical property to decline to a great extent, especially fatigue behaviour.So not being able to satisfy the application of nuclear power field actually.
As described above, in conjunction with current membrane configuration and production technology, it is mainly simple using single-layer or multi-layer fiber
Stacking and rubber are suppressed, often due to cannot uniformly be unfolded during the defect of fiber itself or laying, in diaphragm
On cause defect part so that mechanical property and fatigue behaviour decline.
Since fiber can only be distributed in middle layer or the surface layer of diaphragm, be simply bonded with rubber part, only one layer or
Two layers of faying face, in conjunction with not being very complete, so being only entire diaphragm provides limited mechanical strength and endurance life.On
The problem of problem of stating is this field urgent need to resolve.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of radiation hardness rubbers for taking into account mechanical strength and radiation shield performance
Glue diaphragm.
In order to solve the above technical problem, the present invention provides scheme be: a kind of radiation resistant rubber diaphragm, including diaphragm sheet
Body and the braiding layer for being interspersed in the septum body；
The braiding layer includes multiple steric configuration units being made of fiber, and the fiber is with radiation shield performance
Functional fiber；
The septum body includes following components by mass parts:
50~100 parts of rubber, 15~40 parts of screener, 2~5 parts of auxiliary agent, 2~6 parts of antiager, 2~20 parts of vulcanizing agent.
The stereo weaving structure that the application uses, the stereochemical structure unit of composition, since fiber sheet is as shielding material, energy
Enough effective radiation-screenings, simultaneously because fiber is configured to the cage structure of 3 D stereo in septum body, which can be with
Some reflections of radiation, the radiation sprawling of secondary reflection and scattering are effectively prevented, 3 D stereo braiding layer can be improved greatly
The radiation resistance of diaphragm of rubber, while can also effectively improve the fatigue performance of diaphragm.
Further, the fiber is in basalt fibre, chromium plating polyester fiber and boron carbide polypropylene melt-spun fibers
It is one or more.
Further, the screener is one in titanium dioxide, graphite, chromium oxide, barium carbonate, talcum powder and lead powder
Kind is a variety of.
Further, further including 1~5 part of filler, the filler is magnesia, talcum powder, carbon black, silica flour and three oxygen
Change one of two aluminium or a variety of.
Further, the auxiliary agent is stearic acid, paraffin, white oil, N nitrosodiphenyl amine, polyethylene glycol and fatty acid
