Description
Technical field
The present invention relates to cable fire-proof sealing material of a kind of shutoff penetrability opening and preparation method thereof, particularly a kind of cable sealing module and preparation method thereof.
Background technology
Along with social development, a lot of fields electrifing degree improves constantly, and often cable or other pipeline need to be passed to different spacers.For the medium that prevents spacer both sides exchanges, keep pressure medium, temperature, ingredient stability and the degree of cleaning of requisite space, this just need to pass and locate in addition sealing member at cable or pipeline.Sealing member is dustproof except having, prevent toxic gas, keep the function such as container pressure, also will have the several functions such as fire prevention and radioprotective.Existing cable seal material fire resistance is not high, be difficult for changing, and function is comparatively single, and the work-ing life of material is shorter, as changed not in time, often can cause potential safety hazard.Meanwhile, existing cable seal modules substantially all adopts the mode of hot setting to carry out moulding, and such mode of production is comparatively loaded down with trivial details, and cost is larger.
Summary of the invention
The object of the invention is to be to overcome defect of the prior art, a kind of cable sealing module and preparation method thereof is provided, it adopts the mode of ambient cure to carry out moulding, produce more for convenience, reduced production cost, and this cable sealing module has good flame retardant resistance, stopping property and shielding property, meanwhile, meet fire and can not produce toxic gas, work-ing life is also very long.
In order to realize foregoing invention object, the technical solution used in the present invention is as follows:
A kind of cable sealing module, by forming by the raw material of mass parts metering as follows:
Above-mentioned a kind of cable sealing module, preferably, by forming by the raw material of mass parts metering as follows:
The preparation method of above-mentioned a kind of cable sealing module, preparation process is as follows: first ethenyl blocking polydimethylsiloxane and phenylene silicone rubber part are joined in multi-functional dispersing mixer, under 20～25 DEG C of conditions, mix 20～30min, then add p-terphenyl, m-terphenyl, ferric oxide, titanium dioxide three aluminium, zinc oxide, magnesium hydroxide, zinc borate, gas-phase silica, MQ silicone resin, be uniformly mixed 40～60min, add again Pt catalyzer, dispersed with stirring 30～40min, finally adding hydrogen content is 0.2% containing hydrogen silicone oil, fully be uniformly mixed after 10～15min, pour in mould, it is 25 DEG C in temperature, relative humidity is in 60% environment, to leave standstill degassed and curing 20～40min, after the demoulding, obtain each assembly work in-process, then combine and obtain cable sealing module.
P-terphenyl, m-terphenyl in the present invention's formula are antiradiation agent, and it does not affect the crosslinking curing of silastic material, can improve the radioresistance of silastic material yet; Ferric oxide, titanium dioxide three aluminium and zinc oxide are heat-resisting additive, can improve the thermostability of material, this is mainly to utilize its oxidation-reduction to eliminate the free radical that silicon rubber side group oxygenolysis produces, thereby stops the catabiosis such as silastic material occurs to be cross-linked, sclerosis; Magnesium hydroxide and zinc borate with improving the ceramic layer forming after the flame retardant properties of silicon rubber enhanced burning.Seal modules of the present invention and existing cable seal material compared, flame retardant resistance, stopping property and shielding property excellence; Meet fire and can not produce toxic gas, exceed 40 years work-ing life; Adopt the mode of ambient cure to carry out moulding, preparation technology is simple, reduces costs.
