It is a kind of using nitrile rubber as the rubber blend of rubber master batch, including following raw material: nitrile rubber, zinc oxide, stearic acid, promotor, anti-aging agent, carbon black, phenolic resin, crosslinking agent.
Description
Technical field
The present invention relates to field of rubber technology, and in particular to a kind of using nitrile rubber as the rubber blend of rubber master batch and its system
Water pump packing ring made of standby.
Background technique
It is equipped with water pump packing ring in fresh water pump packing cavity, is used for connecting bushing, the fresh water pump that present China uses is international
General structure, the water pump packing ring in fresh water pump packing cavity is ironcasting.The water pump packing ring of iron and steel material quality is logical there are one
Chang Wenti-corrosion.Now, the method that domestic each water pump works all solves the problems, such as this in positive searching.And rubber parts because its at
The advantages that this is lower, hardness reaches, oil resistant, corrosion-resistant, non-corrosive becomes most suitable water pump packing ring raw material.
During preparing water pump packing ring with rubber parts replacement steel and iron parts, maximum difficult point is exactly to need rubber parts can
Reach the hardness of steel and iron parts.And it is well known that the carbon black as reinforcing agent is to improve the most common raw material of rubber performance.Such as
Chinese patent document 20150814088.5 discloses a kind of high hardness butadiene-acrylonitrile rubber silica white blend and preparation method thereof,
It is also to use nitrile rubber as rubber master batch, carbon black prepares the mixture of high rigidity as reinforcing agent.Due to its content of carbon black
Still not high enough, therefore Chinese patent document 20150814088.5 discloses a kind of high hardness butadiene-acrylonitrile rubber silica white blend
Still it can not reach the hardness of steel.
In short, if the hardness to rubber parts can reach steel and iron parts, higher content of carbon black is just had to, but this
It just will appear various problems in its mixing process, carbon black is excessively high, is difficult to disperse in mixing process, and allowing for calendering process needs
Last very long is wanted, and long mixing time will lead to sizing material incipient scorch, product is unqualified；Carbon black is on the low side, and is unable to reach hard
Spend index and other performance indicators.
Summary of the invention
The first object of the present invention is to provide a kind of using nitrile rubber as the rubber blend of rubber master batch, and it is suitable to have selected
The carbon black of content enables rubber parts hardness higher, and does not need too long of mixing time and avoid sizing material incipient scorch, basic herein
On reinforcement is further carried out using phenolic resin so that phenolic resin and carbon black, which cooperate, enhances rubber parts, being equivalent to is reduced
Reach the dosage of carbon black used by steel hardness.
The second object of the present invention is to provide a kind of water that the rubber blend with nitrile rubber temperature rubber master batch is prepared
Pump packing ring, be rubber material, can but reach the hardness of steel, for replace fresh water pump packing cavity medium cast iron part preparation and
At water pump packing ring.
It is a kind of using nitrile rubber as the rubber blend of rubber master batch, including following raw material: nitrile rubber, zinc oxide, stearic acid,
Promotor, anti-aging agent, carbon black, phenolic resin, crosslinking agent.
Wherein, carbon black includes carbon black N330 and carbon black N660, and promotor includes altax and Vulcanization accelerator TMTD, crosslinking agent
Including vulcanizing agent DCP and sulphur.
Specifically, above-mentioned raw materials are following parts by weight:
The nitrile rubber of 80 ~ 120 parts by weight, the zinc oxide of 4 ~ 6 parts by weight, the stearic acid of 0.5 ~ 2 parts by weight, 1 ~ 2 parts by weight
Altax, Vulcanization accelerator TMTD part of 0.2 ~ 0.8 parts by weight, the anti-aging agent of 1 ~ 3 parts by weight, 70 ~ 90 parts by weight carbon black N330,
The carbon black N660 of 10 ~ 30 parts by weight, the phenolic resin of 25 ~ 35 parts by weight, the vulcanizing agent DCP of 2 ~ 5 parts by weight, 0.1 ~ 1 parts by weight
Sulphur.
Further, above-mentioned raw materials are following parts by weight:
The nitrile rubber of 100 parts by weight, the zinc oxide of 5 parts by weight, the stearic acid of 1 parts by weight, 1.5 parts by weight altax,
The Vulcanization accelerator TMTD of 0.5 parts by weight, the anti-aging agent of 2 parts by weight, 80 parts of carbon black N330,20 parts of carbon black N660,30 parts of phenol
Urea formaldehyde, 3 parts of vulcanizing agent DCP, 0.5 part of sulphur.
As a kind of optimal technical scheme, the anti-aging agent is DFC-34.
A kind of water pump packing part being prepared using nitrile rubber as the rubber blend of rubber master batch, by above-mentioned rubber blend
Merging mold is prepared, including following procedure:
Step 1: by nitrile rubber and anti-aging agent, zinc oxide, stearic acid, carbon black N330, carbon black N660, altax, promotor
The mixer of TMTD, phenolic resin investment high temperature and pressure, by the kneading of short time, disperse, are mixed to get rubber compound；Mixer
Pressure 0.6-0.8MPA, 100-120 DEG C of temperature, 13 ~ 18min of working time.
Step 2: being cooled to 40 ~ 60 DEG C to sizing material, vulcanizing agent DCP and sulphur is added, continues refining glue on a mill；
Step 3: it is uniform to sizing material, rubber compound is injected into mold, cools and solidifies, obtains water pump packing ring.
Compared with the prior art, the present invention has the following beneficial effects:
The present invention carries out reinforcement to nitrile rubber using carbon black, it is contemplated that carbon black is wanted can be fully dispersed in mixing process,
Therefore, content of carbon black is controlled, this content guarantees so that the hardness of rubber blend is high, while not needing too long
Mixing time avoids the problem that rubber blend incipient scorch.But the content of this carbon black is still not enough to that rubber blend is allowed to reach
Therefore the intensity of steel and iron parts by the further reinforcement of phenolic resin, remaining insufficient hardness is supplied.Carbon black and phenolic resin
Collective effect under, enable carbon black to reach the hardness of steel and iron parts.Meanwhile phenolic resin also acts as the work of auxiliary carbon black dispersion
With.
In the present invention, double cross-linking systems are used, sulphur promotes the crosslinking of nitrile rubber and carbon black, and vulcanizing agent DCP promotes
The crosslinking of phenolic resin and nitrile rubber, carbon black and other compositions.In mixing process, temperature is higher than 100 DEG C, and phenolic resin exists
It is liquid in high temperature, is crosslinked with vulcanizing agent, steel frame is formed, to cooperate black-reinforced hardness.
It should be noted that steel and iron parts have very much, hardness is different, what heretofore described rubber blend can reach
Hardness refers to the hardness compared with mild steel iron.
