Description
Technical field
The present invention relates to rubber product preparation field, particularly a kind of rubber vulcanization process.
Background technology
Vulcanization is that rubber is built bridge the general designation of crosslinking, and rubber is nugatory before no vulcanization, when rubber and other
By crosslinking agent in certain temperature and forming under the pressure, rubber mix after the auxiliary materials such as auxiliary material, such as filler, auxiliary agent are well mixed
Material is allowed to that cross-linked network occurs by crosslinking agent, and the valuable of various performances can be provided after being be combined with each other between molecule
Material.Rubber made from existing sulfurization technology, its usual pulling force and hardness are poor, it is impossible to meet that the needs of using waves.
The content of the invention
The present invention solves the technical problem of provide a kind of rubber vulcanization process, it is possible to increase the vulcanization matter of rubber
Amount, improve rubber quality.
In order to solve the above technical problems, one aspect of the present invention is：A kind of rubber vulcanization process is provided, its
Including：
First, prepare raw material：Design parameter in technological requirement, calculate raw material proportioning；
Second, material is kneaded：Butadiene-styrene rubber, cis-butadiene cement, zinc oxide, stearic acid, age resistor, accelerator will be placed in after rubber cut-parts
It is kneaded in mixture, melting temperature is 50 ~ 100 DEG C, and mixing time is 15 ~ 25min；
3rd, the vulcanization of rubber：Temperature, time and the pressure of adjustment vulcanization are tentatively vulcanized；
4th, detection check：The rubber cut-parts tentatively vulcanizated carry out numerical value detection, to the low temperature resistant, wear-resisting, resistance to of rubber cut-parts
Drawing ability carries out data test；
5th, sulfidization molding：The rubber cut-parts for detecting qualified are placed in mould, clamping pressure is ensured after mould matched moulds
Make formed product.
Preferably, in the 3rd step, the temperature of vulcanization is 150 ~ 180 DEG C, and the time of vulcanization is 10 ~ 15min, vulcanization
Pressure be 30Mpa.
Preferably, in the 4th step, the scope of low temperature resistant test is -50 ~ -35 DEG C；The wear-resisting grade of wear-resisting test
For 350；Scope >=20Mpa of resistance to tensile test.
The beneficial effects of the invention are as follows：A kind of rubber vulcanization process, the smooth heating of the curing temperature control used in the past
Vulcanization process is compared, and advantage and difference are being controlled in whole sulfidation to pressure, make production process more
Add easy operation.
Embodiment
Presently preferred embodiments of the present invention is described in detail below so that advantages and features of the invention can be easier to by
It will be appreciated by those skilled in the art that apparent clearly defined so as to be made to protection scope of the present invention.
The embodiment of the present invention includes：A kind of rubber vulcanization process, its step include：
First, prepare raw material：Design parameter in technological requirement, calculate raw material proportioning；
Second, material is kneaded：Butadiene-styrene rubber, cis-butadiene cement, zinc oxide, stearic acid, age resistor, accelerator will be placed in after rubber cut-parts
It is kneaded in mixture, melting temperature is 50 ~ 100 DEG C, and mixing time is 15 ~ 25min；
3rd, the vulcanization of rubber：Temperature, time and the pressure of adjustment vulcanization are tentatively vulcanized；The temperature of vulcanization is 150 ~ 180
DEG C, the time of vulcanization is 10 ~ 15min, and the pressure of vulcanization is 30Mpa；
4th, detection check：The rubber cut-parts tentatively vulcanizated carry out numerical value detection, to the low temperature resistant, wear-resisting, resistance to of rubber cut-parts
Drawing ability carries out data test；The scope of low temperature resistant test is -50 ~ -35 DEG C；The wear-resisting grade of wear-resisting test is 350；Resistance to pulling force
Scope >=20Mpa of test；
5th, sulfidization molding：The rubber cut-parts for detecting qualified are placed in mould, clamping pressure is ensured after mould matched moulds
Make formed product.
According to above-mentioned processing step, the design parameter of its design of the other embodiment 1 ~ 6 of this programme use is as shown in the table：
This technique is heated up by graded, so as to control sulfidation.What is controlled with the curing temperature used in the past is flat
Sliding temperature vulcanization process is compared, and advantage and difference are being controlled in whole sulfidation to pressure, make production
Process is more prone to operate, and can reduce conversion error between temperature and pressure in process of production causes caused by insufficient pressure
Defect, it can more increase solubility of the sizing material to gas on microcosmic, in the generation for macroscopically showing as reducing bubble.By right
The tracking and testing repeatedly of sizing material, the physical and mechanical properties of sizing material have good guarantor after curing after this sulfur form vulcanization
Card.
The above embodiments merely illustrate the technical concept and features of the present invention, and its object is to allow person skilled in the art
Scholar can understand present disclosure and be carried out, and it is not intended to limit the scope of the present invention, all according to the present invention
The equivalent change or modification that Spirit Essence is made, it should all cover within the scope of the present invention.
