Abstract
A kind of composition containing high-temperature silicon disulfide rubber of disclosure of the invention, it is characterised in that it is characterised in that it includes following parts by weight of component：85 90 parts of sulphurated siliastic, 45 parts of zinc oxide, 0.8 1.2 parts of stearic acid, 24 parts of additive, 36 48 parts of aromatic naphtha.The filler is diatomite, bentonite, the mixture of bead.The high-temperature silicon disulfide rubber that the present invention contains has high-temperature behavior.Although the intensity of silicon rubber is only the half of natural rubber or some synthetic rubber under room temperature, under the hot environment more than 200 DEG C, silicon rubber remains to keep certain pliability, resilience and case hardness, and mechanical property is without significant change.It is tasteless and high-temperature silicon disulfide rubber silicon is nontoxic, it is odorless, with tissue adhesion, there is blood coagulation resisting function, to the reactive considerably less of injected organism tissue.Particularly suitable as medical material.
Description
Technical field
The present invention relates to a kind of composition containing high-temperature silicon disulfide rubber.
Background technology
High-temperature silicon disulfide rubber, which refers to the process of that polysiloxanes becomes elastomer-forming, to be sulfided into by high temperature (110-170 DEG C)
Type.It is mixed into reinforced filling, vulcanizing agent etc. mainly using the Polymethyl methacrylate of high molecular weight as raw rubber, is heating
The lower vulcanization elastomer-forming of pressurization.The reinforcement of silicon rubber is mainly various types of white carbons, can make the intensity of vulcanizate increase number
Ten times.Sometimes for reducing cost or improving properties of rubber and the imparting various special performances of vulcanizate, also add corresponding each
Kind additive.Vulcanizing agent is various organic peroxide or addition reaction catalyst.
The content of the invention
The object of the present invention is to provide a kind of composition containing high-temperature silicon disulfide rubber.
In order to achieve the above object, the present invention is realized using following technical scheme：
A kind of composition containing high-temperature silicon disulfide rubber, including following parts by weight of component：85-90 parts of sulphurated siliastic,
4-5 parts of zinc oxide, 0.8-1.2 parts of stearic acid, 2-4 parts of additive, 36-48 parts of aromatic naphtha.The filler is diatomite, swelling
Soil, the mixture of bead.
Preferably, the sulphurated siliastic is high-temperature silicon disulfide rubber.
Preferably, the Mixing ratio by weight of the fiber and resin is 1:1.5.
Beneficial effect of the present invention：The high-temperature silicon disulfide rubber that the present invention just has has high-temperature behavior.Although silicon rubber under room temperature
The intensity of glue is only the half of natural rubber or some synthetic rubber, but under the hot environment more than 200 DEG C, silicon rubber remains to
Certain pliability, resilience and case hardness are kept, and mechanical property is without significant change.And high-temperature silicon disulfide rubber silicon without
Poison, it is tasteless, it is odorless, with tissue adhesion, there is blood coagulation resisting function, to the reactive considerably less of injected organism tissue.It is especially suitable
Cooperate as medical material.
With reference to embodiment, the present invention is further described.
