Abstract
The invention discloses a kind of valve sealing ring plastic rubber materials, are made of raw material from the following weight：60-70 parts of methyl trifluoro propyl silicon rubber, 30-40 parts of high polymerization degree polyethylene, 2-4 parts of zinc oxide, 1-4 parts of anti-aging agent RD, 2-4 parts of vulcanizing agent, 1-2 parts of auxiliary curing agent, 1-2 parts of nanometer grade silica.By adopting the above-described technical solution, the invention has the advantages that：The formula of the invention is reasonable, and raw material is easy to get, and the valve sealing ring produced using plastic rubber material of the present invention, long service life, anti ageing property is good, in addition, resistance to corrosion is strong.
Description
Technical field
The present invention relates to a kind of sealing ring, specifically a kind of valve sealing ring plastic rubber material.
Background technique
Sealing ring also known as O-ring seal, are a kind of accessories to sealing function, and the requirement for sealing ring is as follows：
In addition to the general requirement that should have sealing ring material, sealing ring is also noted that following conditions：
(1) high resilience and resilience；
(2) mechanical strength appropriate, including tensile strength, elongation and tearing toughness etc..
(3) performance is stablized, and is not easy to be swollen in the medium, thermal pinch（Joule effect）It is small.
(4) easy processing forms, and is able to maintain accurate size.
(5) do not corrode contact surface, not pollution medium etc..
The most suitable and most common material for meeting above-mentioned requirements is rubber, so sealing ring rubber material system multi-purpose greatly
At.
Currently, the anti-aging property due to rubber seal is poor, thus the service life of sealing ring is substantially reduced, especially
It is it is higher applied to the sealing ring requirement on valve, in addition to anti-aging property, also have higher requirement to its resistance to corrosion.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of valve sealing ring plastic rubber materials.
In order to solve the above technical problems, the technical scheme is that：A kind of valve sealing ring plastic rubber material, by following heavy
The raw material of amount part is made：60-70 parts of methyl trifluoro propyl silicon rubber, 30-40 parts of high polymerization degree polyethylene, 2-4 parts of zinc oxide, prevent
1-4 parts of old agent RD, 2-4 parts of vulcanizing agent, 1-2 parts of auxiliary curing agent, 1-2 parts of nanometer grade silica.
Preferably, a kind of valve sealing ring plastic rubber material, is made of raw material from the following weight：Methyl trifluoro propyl silicon
60 parts of rubber, 30 parts of high polymerization degree polyethylene, 2 parts of zinc oxide, 1 part of anti-aging agent RD, 2 parts of vulcanizing agent, 1 part of auxiliary curing agent, nanometer
1 part of grade silicon dioxide.
Preferably, a kind of valve sealing ring plastic rubber material, is made of raw material from the following weight：Methyl trifluoro propyl silicon
65 parts of rubber, 35 parts of high polymerization degree polyethylene, 3 parts of zinc oxide, 2.5 parts of anti-aging agent RD, 3 parts of vulcanizing agent, 1.5 parts of auxiliary curing agent,
1.5 parts of nanometer grade silica.
Preferably, a kind of valve sealing ring plastic rubber material, is made of raw material from the following weight：Methyl trifluoro propyl silicon
70 parts of rubber, 40 parts of high polymerization degree polyethylene, 4 parts of zinc oxide, 4 parts of anti-aging agent RD, 4 parts of vulcanizing agent, 2 parts of auxiliary curing agent, nanometer
