Silicone oil.The auxiliary agent is used as vulcanizing agent, to assist the realization of sulfidation.In the present embodiment, the auxiliary agent can be
2.5- dimethyl -2.5- bis(t-butylperoxy) hexane.
The manufacturing method of the present invention so, it is possible enhancing product pulling force and screen resilience using double sulfuration process, anti-to improve
The waterproof sealing effect of gelatine sleeve.In primary vulcanization treatment process, related technological parameter includes: curing temperature: 180 DEG C
~190 DEG C, vulcanization time: 280s~320s.Preferably, vulcanization time: 300s.It is involved in second of sulfidation processes
Technological parameter include: curing temperature: 140 DEG C~160 DEG C, vulcanization time: 1500s~2000s.Curing temperature: 150 DEG C, sulphur
Change the time: 1800s.
The step of being surface-treated specifically includes that the flash on the intermediate products surface obtained after trimming vulcanization.In addition, right
In obtained water-proof rubber sleeve, further includes: to product the step of testing, the project of inspection includes surface impurity, flash etc..
The resilience of the water-proof rubber sleeve to after is tested as follows below:
There is provided water-proof rubber sleeve sample and control sample, wherein water-proof rubber sleeve sample has to be documented in the present embodiment
The water-proof rubber sleeve of structure as described above and ingredient；Control sample be with water-proof rubber sleeve in the present embodiment with the anti-of sample ingredient
Gelatine sleeve, but it only carries out a vulcanizing treatment, and the control sample does not have in the present embodiment possessed by water-proof rubber sleeve
First reinforcing rib and the second reinforcing rib, remaining is all the same.
The original outer diameter size and internal diameter of water-proof rubber sleeve sample and control sample are measured and recorded respectively.
Water-proof rubber sleeve sample and control sample are respectively placed in same compression mould, the two is surveyed under identical condition
Examination, it may be assumed that
Water-proof rubber sleeve is compressed in radial directions by compression mould, decrement so that water-proof rubber sleeve seal chamber
Subject to closure, at -20 DEG C after pressure maintaining for 24 hours, compression mould is opened.Water-proof rubber sleeve sample is taken out, to its outer diameter and interior
Diameter size measures.Through measuring, front and back twice, the dimension difference of water-proof rubber sleeve of the invention in ± 0.5mm, control sample
The dimension difference of water-proof rubber sleeve is in ± 5mm.
It follows that the elastic standard of water-proof rubber sleeve of the invention meets the use standard of water-proof rubber sleeve.In addition, by
In a practical situation in water-proof rubber sleeve of the invention, it needs to keep certain resilience at low ambient temperatures, therefore pressure maintaining is set
Locating temperature is -20 DEG C for 24 hours.
However, also found by above-mentioned test, water-proof rubber sleeve of the invention also shows the cold resistance for having certain, i.e., anti-
Gelatine sleeve can show to have lower in -20 DEG C of condition in being restored to initial form within the scope of the dimension difference of permission
Brittleness temperature, principle is unknown, may be related to post-cure, it is also possible to reinforcement structure feature possessed by water-proof rubber sleeve
Correlation, and then improve the cold resistance of water-proof rubber sleeve.
Based on water-proof rubber sleeve as described above, the present invention also provides a kind of cable connection assemblies.
As shown in Figure 4,5, the cable connection assembly includes: the cable connector 300 for being connected to 200 one end of cable, set
Loaded on the water-proof rubber sleeve as described above 100 on the cable connector 300.
