Description

Technical Field

[0001] The present invention relates to the technical field of rubber waterstops, and particularly to a composite rubber waterstop with high viscosity and elasticity and its production process. Background Art

[0002] There are many joints on buildings. From a functional perspective, these joints have various types. For example, bridge expansion joints are set to compensate for the thermal expansion and contraction of the bridge deck, settlement joints are set to compensate for the dislocation caused by the settlement of buildings, and seismic joints are set to avoid the situation where a building is too long to meet the seismic requirements. In order to carry out water isolation treatment for these joints, we need to use a component called a rubber waterstop. There are various types of waterstops, which are mainly used in infrastructure projects, underground facilities, tunnels, sewage treatment plants, water conservancy, subways and other projects, and are used for the concrete pouring of expansion joints such as gates, dam bottoms, building projects, and underground buildings. Among them, rubber waterstops are the most widely used and are currently commonly used in the waterproofing and anti-seepage of construction joints in tunnel projects.

[0003] When the existing waterstops are in use, since the parts that need to be waterproofed are relatively long, multiple waterstops need to be installed. The adjacent waterstops are subjected to cold jointing or hot jointing treatment at the joints, and the two butting end faces are prone to stagger, resulting in the disadvantage that the surface of the connected waterstop cannot be kept flat.

[0037] Please refer to Figures 1 to 2 and Figure 5 , the present invention provides a technical solution: a composite rubber waterstop with high viscosity and elasticity and its production process, including: a waterstop inner core 21, which is arranged inside the waterstop body 1.

By providing the anti-puncture layer 24, the anti-puncture effect of the waterstop body 1 can be improved. With the cooperation of the partition 20, if the waterstop body 1 is punctured, the liquid will flow into the corresponding waterstop cavity 19, thus preventing the liquid from spreading around. The provided waterproof rubber membrane 23 can play a waterproof role, thereby improving the waterproof effect of the rubber waterstop.

[0038] In the invention: the production process of the composite rubber waterstop with high viscosity and elasticity is as follows:

[0039] S1. Raw material plasticizing and mixing: Using natural rubber, EPDM (ethylene propylene diene monomer rubber), EVA (ethylene vinyl acetate copolymer), PVC (polyvinyl chloride), and PE (polyethylene), the natural rubber is plasticized by a plasticizing device, and then the plasticized natural rubber and auxiliary materials are mixed by a mixing device; and then it is vulcanized to be made.

[0040] S2. Processing and forming: First, determine the material indexes for processing, then select a mold on the vulcanizing device and install it on the vulcanizer. While the vulcanizer is heating up, the mold will also be heated together with the vulcanizer. By adding the mixed raw materials into the mold of the vulcanizer, after the mold is closed, start the descent switch when the waterstop belt has been vulcanized for one minute, appropriately deflate the waterstop belt to increase the fluidity of the rubber compound and reduce the generation of air bubbles, so that the rubber compound fills the mold cavity and is processed and formed.

[0041] S3. Waterstop belt inspection: After the waterstop belt is vulcanized, start the oil pump descent switch of the vulcanizer, pull out the waterstop belt core from the front end of the mold of the vulcanized waterstop belt, cut off the rubber sheets on both sides of the waterstop belt, and check whether there are problems such as eccentric holes, air bubbles, lack of rubber, and broken ribs on the waterstop belt. If there are problems such as lack of rubber and broken ribs that can be repaired, promptly repair them by returning them to the mold for treatment.

[0042] In summary, for the composite rubber waterstop with high viscosity and elasticity and its production process, during use, first place the waterstop body 1 in a suitable position. When the length of the waterstop part is short and there is no need to install multiple waterstop bodies 1, grouting concrete can be directly used to fix the waterstop part. Through the first raised rib 7 and the second raised rib 8 provided on the waterstop body 1, the waterstop body 1 can be better stressed. The deformation ring 2 and the waterstop inner core 21 are made of rubber material. When the waterstop body 1 is pulled, the deformation ring 2 can deform. And there is a reinforcing wire mesh 22 inside the waterstop inner core 21, which can enhance the strength of the waterstop inner core 21 and reduce the situation of the waterstop inner core 21 being torn. The anti-puncture layer 24 provided in the waterstop body 1 is a soft iron sheet, which has a certain anti-puncture effect and can effectively reduce the situation of the waterstop body 1 being punctured. If the waterstop body 1 is punctured, under the partition cooperation of the partition 20, the liquid will flow into the corresponding waterstop cavity 19, thus preventing the liquid from spreading around. The waterproof film 23 provided can play a waterproof role, thereby improving the waterproof effect of the rubber waterstop. This waterstop is made of natural rubber and has good viscosity and elasticity. When the length of the waterstop part is long and multiple waterstop bodies 1 need to be installed, through the connection hole 3 provided at one end of the deformation ring 2, the user can align the deformation ring 2 on the second waterstop body 1 with the deformation ring 2 on the first waterstop body 1. At the other end of the deformation ring 2 on the second waterstop body 1, there are a fixing block 6 and a connecting piece 5 made of soft rubber, so that the connecting piece 5 can be inserted into the connection hole 3 and engaged with the limit groove 4, thereby positioning and assembling the two waterstop bodies 1. Then, through the limit holes 14 provided on both sides of the two waterstop bodies 1, align the limit block 13 on the first fixing member 11 with the limit hole 14 on one side, and horizontally push the first fixing member 11 so that the first fixing member 11 is connected to the two waterstop bodies 1. Then, connect the second fixing member 12 to the limit holes 14 at the other end of the two waterstop bodies 1 in the same way. After the two waterstop bodies 1 are connected, through the installation holes 16 provided on the second fixing member 12 and the first fixing member 11, align the connecting block 15 on the upper fixing strip 9 with the installation hole 16, and then vertically move the upper fixing strip 9 so that the connecting block 15 is inserted into the installation hole 16. Then tighten the limit screws 17 on the second fixing member 12 and the first fixing member 11 so that the front end of the limit screw 17 is inserted into the connection groove 18. Then, use the same method to place the lower fixing strip 10 on the second fixing member 12 and the first fixing member 11. This can limit the two waterstop bodies 1 and keep the waterstop bodies 1 flat after connection, thus facilitating the heat treatment connection of the connection part of the two waterstop bodies 1 and reducing the situation of the butt end faces of the two waterstop bodies 1 being staggered.

[0043] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, shall be covered by the protection scope of the present invention.
