Description

Technical Field

[0001] The present application belongs to the technical field of sealing strips, and specifically relates to an acidic silicone sealing strip. Background Art

[0002] Acid silicone sealant strips are usually made of acid silicone materials and are used to seal and caulk various building surfaces such as glass, metal, ceramics, tiles and concrete, etc. This type of sealant strip is widely used in the construction industry.

[0003] For example, a patent with the announcement number CN214835950U discloses an environmentally friendly flame-retardant silicone sealant strip, which includes an inner sealant strip, the outer surface of the inner sealant strip is fixedly connected with a sealant strip outer sleeve, an inner cavity is formed between the sealant strip outer sleeve and the inner sealant strip, and a partition is arranged inside the inner cavity. The environmentally friendly flame-retardant silicone sealant strip has a single-component low-viscosity acrylic flame-retardant coating arranged on the sealant strip outer sleeve, so that the sealant strip outer sleeve has good flame retardancy, and the thermal aging performance is maintained at 130°C. It has excellent insulation, moisture-proof, anti-leakage, shock-proof, dust-proof, anti-corrosion, anti-aging, and corona resistance. The inner cavity formed between the sealant strip outer sleeve and the inner sealant strip, and the inert gas argon in the inner cavity can prevent the heat on the sealant strip outer sleeve from being transferred to the inner sealant strip, causing the inner sealant strip to soften and affect the use of the sealant strip.

[0004] However, the environmentally friendly flame-retardant silicone sealing strip of the application lacks a structure to enhance the bonding effect during installation, resulting in insufficient cohesion and adhesion between the strip and the substrate, which in turn leads to poor stability. Utility Model Content

[0005] The purpose of the present application is to provide an acidic silicone sealing strip in order to solve the problem that the above-mentioned environmentally friendly flame-retardant silicone sealing strip lacks a structure to enhance the bonding effect during installation, resulting in insufficient cohesion and adhesion between the strip and the substrate, and further leading to poor stability.

[0006] The technical solution adopted in the present application is as follows: an acidic silicone sealing strip, comprising a strip body, a substrate body inserted below the strip body, an inner strip inside the strip body, a substrate side panel inside the substrate body, an insertion strip fixedly connected to the bottom side end of the inner strip, an insertion cavity is provided below the insertion strip, the substrate body includes a protrusion inside, the insertion cavity is slidably connected with the protrusion, the substrate body is provided with a substrate slot, the surface of the substrate slot is slidably connected with the insertion strip, and an adhesive layer is provided inside the insertion strip.

[0007] By adopting the above technical solution, the plug-in strip installed in the rubber strip body can be plugged and installed on the surface of the protrusion in the substrate body, and the size of the plug-in cavity is slightly larger than the size of the protrusion. The inner strip is the supporting structure of the rubber strip body. After the inner strip is plugged into the rubber strip body, it can fit with the inner wall of the substrate side panel of the substrate body. During installation, the curing agent is injected into it through the injection layer in the plug-in strip, and then the rubber strip body is inserted into the interior of the substrate body as a whole, so that the bottom of the plug-in strip fits the surface of the substrate slot, and then the lower end of the plug-in strip is pressed down to allow the curing agent stored in the adhesive layer to fully contact the surface of the substrate slot, and then it can quickly solidify into a hard sealing layer when it comes into contact with moisture in the air, thereby improving the stability and sealing strength of the connection. Improve the cohesion and adhesion between the rubber strip and the substrate.

[0008] In a preferred embodiment, the outer end of the inner strip is attached to a substrate side plate, the top outer end of the inner strip is fixedly connected to an outer arc layer, and the surface of the outer arc layer is coated with an anti-aging coating.

[0009] By adopting the above technical solution, the anti-aging coating can protect the surface of the outer arc layer, improving the oxidation resistance and weather resistance of the device. The outer arc layer is used to protect the outer end of the substrate side plate, and at the same time, the rubber strip body can clamp the outer wall of the substrate body on the outside to improve the stability of the device.

[0010] In a preferred embodiment, an inner end of the outer arc layer is fixedly connected to an elastic pad, and an inner end of the elastic pad is slidably connected to a substrate side plate.

[0011] By adopting the above technical solution, when the outer end of the outer arc layer is squeezed, the elastic pad will be driven to move inward, and the elastic pad will squeeze the surface of the substrate side plate to play a role of buffering protection.

[0012] In a preferred embodiment, a glue injection layer is provided on the top of the front end of the plug-in strip.

[0013] By adopting the above technical solution, the glue injection layer is used to inject a curing agent or an adhesive for strengthening the connection before installation.

[0014] In a preferred embodiment, an upper protective layer is fixedly connected to the top inner end of the inner strip.

[0015] By adopting the above technical solution, the upper protective layer is an elastic structure, which can protect the internal structure of the rubber strip body.

[0016] In a preferred embodiment, a plurality of reinforcing ribs are fixedly connected to the bottom end of the upper protective layer, and a plug-in strip is fixedly connected to the bottom end of the reinforcing ribs.

[0017] By adopting the above technical solution, when the upper protective layer is pressed downward, the reinforcing ribs can be driven to press down the surface of the plug-in strip, thereby squeezing the inside of the adhesive layer, allowing the curing agent in the adhesive layer to precipitate to the surface of the substrate slot, thereby curing into a hard sealing layer.

[0018] In a preferred embodiment, a supporting rib is fixedly connected to the inner end of the inner strip and is located below the upper protective layer.

[0019] By adopting the above technical solution, the supporting ribs can connect the inner strips on both sides to form an H-shaped structure, thereby improving the stability and strength of the overall structure of the rubber strip body.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0021] In this application, a curing agent is injected into the plug-in strip through the injection layer in the plug-in strip, and then the main body of the rubber strip is inserted into the interior of the substrate body as a whole, so that the bottom of the plug-in strip fits the surface of the substrate slot, and then the upper protective layer is pressed down, driving the reinforcing ribs to press down the surface of the plug-in strip, and then the inside of the adhesive layer is squeezed to allow the curing agent stored inside the adhesive layer to fully contact the surface of the substrate slot, and then it can be quickly cured into a hard sealing layer when it comes into contact with moisture in the air. The outer arc layer is used to protect the outer end of the substrate side plate. When the outer end of the outer arc layer is squeezed, it will drive the elastic pad to move inward, and the elastic pad will squeeze the surface of the substrate side plate, playing a role of buffer protection. When the outer end of the outer arc layer is squeezed, it will drive the elastic pad to move inward, and the elastic pad will squeeze the surface of the substrate side plate, playing a role of buffer protection.
