Abstract
The utility model belongs to the technical field of sealing strips, and discloses a composite rubber sealing strip for tunnel segments of shield method. The composite rubber sealing strip comprises asealing strip body using ethylene propylene diene monomer rubber as base adhesive; and a first water-absorbent rubber strip using natural rubber as the base material is integrated with the sealing strip body by vulcanization and is arranged on the top surface of the sealing strip body. During manufacture of the composite rubber sealing strip, the sealing strip body and the first water-absorbent rubber strip are integrated by a cold feeding extruder according to the particular formulation and process to form the composite rubber sealing strip before demolding, and the composite rubber sealing strip is then shaped by vulcanization in a microwave vulcanization production line. Accordingly, the sealing strip body is integrated with the first water-absorbent rubber strip by vulcanization, so that the sealing strip is firmly bonded with the first water-absorbent rubber strip even if soaking in water for multiple times, therefore, the production efficiency is greatly enhanced.
Description
Technical field
The utility model belongs to the weather strip technical field, relates in particular to the compound rubber weather strip of a kind of shield construction tunnel duct piece.
Background technology
In recent years, the metro construction development has been alleviated the problem of urban traffic blocking rapidly greatly.In the subway construction construction, introduced shield machine construction, its tunnel is spliced with concrete pipe sheet.Inlaying with ethylene propylene diene rubber around solving the concrete pipe sheet waterproof and be in the section of jurisdiction is the sealing rule body of basic glue, according to the construction line difference, also will paste last layer with the Choropene phenol aldehyde bonding agent in sealing rule surface to deformation joint is the hydro-expansive rubber bar of basic glue with natural gum.Owing to contain high hydroscopic resin as expansion agent in the hydro-expansive rubber bar, after pasting, run into water-absorbing resin such as rainwater and separate out, the hydro-expansive rubber bar needs again during construction to paste again by coming off automatically on the sealing rule body, influences production efficiency.
The utility model content
Problem to be solved in the utility model just provides and a kind ofly seals rule body and the hydro-expansive rubber bar is connected firmly, the compound rubber weather strip of shield construction tunnel duct piece of good water-proof effect.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: comprise with ethylene propylene diene rubber being the sealing rule body of basic glue, the end face of described sealing rule body middle part be provided with composite sulfuration with it be one be the first hydro-expansive rubber bar of basic glue with natural gum.
Its additional technical feature is: the end face middle part of described sealing rule body has the groove that two ends are the V-type groove, and the first hydro-expansive rubber bar is arranged in the groove, and the both sides of the first hydro-expansive rubber bar are the wedge shape projection that is complementary with the V-type groove; The end face of described sealing rule body be provided with composite sulfuration with it be one be the second hydro-expansive rubber bar of basic glue with natural gum.
The compound rubber weather strip of shield construction tunnel duct piece provided by the utility model, compared with prior art, the end face middle part of sealing rule body be provided with composite sulfuration with it be one be the first hydro-expansive rubber bar of basic glue with natural gum.During manufacturing, the sealing rule body and the first hydro-expansive rubber bar are taked special formulation and technology, and utilizing the cooperation cold feed extruder just compound before depanning is the compounded rubber weather strip of one, enters the microwave vulcanization production line more simultaneously, make its common sulfuration setting.The sealing rule body and the first hydro-expansive rubber bar composite sulfuration are one like this, even if repeatedly immersion repeatedly, the sealing rule body and the first hydro-expansive rubber bar are still bonding firmly, have improved production efficiency greatly.And the end face middle part of sealing rule body has the groove that two ends are the V-type groove, the first hydro-expansive rubber bar is arranged in the groove, the both sides of the first hydro-expansive rubber bar are the wedge shape projection that is complementary with the V-type groove, make the sealing rule body and the first hydro-expansive rubber bar in conjunction with tightr.And the end face of sealing rule body be provided with composite sulfuration with it be one be the second hydro-expansive rubber bar of basic glue with natural gum, its waterproof effect is better.
Description of drawings
Fig. 1 is a kind of structural representation of the compound rubber weather strip of the utility model shield construction tunnel duct piece;
