Preparation method of rubber waterstop and rubber waterstop

Abstract

The invention relates to the technical field of waterstops, in particular to a preparation method of a rubber waterstop and the rubber waterstop obtained through the preparation method. The preparation method comprises the steps of mixing materials, manufacturing cover rubber, burying a core, performing pressing, performing vulcanizing and the like. The rubber waterstop comprises a belt body, a tubular structure is arranged on the belt body in the extending direction of the belt body, the rubber waterstop is characterized in that a hose is arranged in the tubular structure, and the outer wallof a hose layer is attached to the inner wall of an outer layer. According to the preparation method, the longer rubber waterstop can be prepared, a plurality of rubber waterstops can be prepared sideby side at the same time, the quality of the rubber waterstops can be improved, human resources can be saved, and the site occupied by production equipment can be reduced. The rubber waterstop provided by the invention is longer in service life and better in waterproof effect.

Description

technical field [0001] The invention relates to the technical field of waterstops, in particular to a method for preparing a rubber waterstop and a rubber waterstop obtained by the preparation method. Background technique [0002] As we all know, there will be many joints on the building, and there are many types of these joints from the functional point of view, such as bridge expansion joints set up to compensate for the thermal expansion and contraction of the bridge deck, and misplaced settlements to compensate for the settlement of the building Joints, anti-seismic joints, etc. in order to prevent the building from being too long to meet the seismic requirements. In order to isolate these joints from water, we need to use rubber waterstops. [0003] see figure 1 , in the known rubber waterstop, water-stop ribs are generally arranged along the extension direction of the waterstop. On the other hand, it can also increase the total length of water flowing through the jo...

AI Technical Summary

Problems solved by technology

[0007] First of all, because the stick needs to be extracted from the rubber waterstop eventually, the stick is solid and cannot be made very long, and is affected by the friction force of the two at the same time. If the waterstop is too long, the friction will be too large without being able to pull out the stick

Therefore, the length of the rubber waterstop produced in the prior art is too long, and in most cases it needs to be spliced ​​together one by one, which increases the difficulty of construction and is not conducive to the waterproof effect.

[0008] Secondly, because the rubber waterstop is made in sections, the quality control of each section of rubber waterstop is difficult to be completely consistent under the existing technical conditions, and the use of different quality waterstops will further increase the difficulty of construction. It will also further reduce the water-proof performance of the seam

[0009] Thirdly, since the stick is in direct contact with the soft belt embryo, the friction force is relatively large, and the process of pulling out the stick will cause damage to the inner wall of the tubular structure of the rubber waterstop, affecting the strength of the tubular structure

[0010] Finally, pulling out sticks generally requires workers to do it manually, which leads to an increase in human resource costs
