TECHNICAL FIELD

[0001] The utility model relates to sealing glue technical field, concretely is a kind of butyl rubber strip for sealing protection. BACKGROUND

[0002] Butyl rubber is a kind of sealing material made of butyl rubber as main raw material, with good weather resistance, aging resistance and lower water vapor permeability. It is widely used in construction, automobile manufacturing, solar equipment and various fields requiring moisture-proof, air-proof, shock absorption and sound insulation. The main features of butyl rubber include excellent bonding performance, excellent weather resistance and aging resistance, lower water vapor permeability and environmental protection and non-toxicity.

[0003] Common butyl rubber is first torn from the surface of release paper when used, and then adhered to the joint to be sealed, so that the sealing effect can be achieved. However, this method cannot meet the working requirements of sealing glue, as the butyl rubber will deform as a whole when the temperature is high, and the butyl rubber will shrink as a whole when the temperature is low, resulting in the expansion of the gap and affecting the sealing effect of butyl rubber. Therefore, a butyl rubber strip for sealing protection is proposed. SUMMARY

[0004] In view of the shortcomings of the prior art, the utility model provides a butyl rubber strip for sealing protection to solve the problem of temperature affecting the sealing effect of butyl rubber.

[0008] Preferably, the butyl rubber body is strip-shaped and similar to a snake shape, the cross-sectional shape of the butyl rubber body is circular, square or elliptical, the diameter of the butyl rubber body is three times the diameter of the main copper wire, which improves the coating effect and avoids the exposure of the main copper wire.

[0009] Preferably, the spiral copper wire is spirally and uniformly wound outside the main copper wire, and the diameter of the spiral copper wire is smaller than the diameter of the main copper wire, which reduces the overall thickness of the main copper wire and the spiral copper wire.

[0010] Preferably, the spherical protrusions are divided into two groups, distributed on the upper and lower sides of the main copper wire, and symmetrically arranged and uniformly arranged on the outside of the main copper wire. In this way, the colloid and the metal structure can be connected fully, stably and firmly.

[0011] Preferably, the butyl rubber body is wrapped around the outer surfaces of the main copper wire, the spiral copper wire and the spherical protrusions, and is shaped into a columnar shape by kneading; the butyl rubber body is in close contact with the surfaces of the main copper wire, the spiral copper wire and the spherical protrusions.

[0012] During processing, the rubber can be put into a screw extruder for extrusion, and the butyl rubber body can be extruded into a circular, square or oval strip to improve the close contact between the butyl rubber body and the surfaces of the main copper wire, the spiral copper wire and the spherical protrusions.

[0013] Preferably, the spherical protrusions are arranged at a distance of 0.5-2.5 cm, and the surfaces of the spherical protrusions are roughened; the protrusions are in contact with the colloid through the rough surfaces, which can improve the contact strength.

[0014] Preferably, the butyl rubber body is wrapped with release paper, and the release paper is provided with a break point crease; the break point crease has a length of 5-10 cm; the break point crease can be easily torn off at the break point crease during operation; the break point crease is composed of a plurality of linear holes penetrating the surface of the release paper, which makes the tearing and separation of the release paper more convenient and faster.

[0015] Compared with the prior art, the butyl rubber strip for sealing and protection has the following advantages:

[0016] 1. The butyl rubber strip for sealing and protection is provided with a main copper wire inside the butyl rubber body, which can provide a shaping support when the butyl rubber body softens at high temperatures, so that the butyl rubber body maintains its shape; in cold weather, the butyl rubber body can be softened by heating the main copper wire, thereby achieving a more tightly sealed and waterproof effect, and improving the quality of the butyl rubber roll.

[0017] 2. The butyl rubber strip for sealing and protection is provided with a spiral copper wire and a spherical protrusion, which increases the contact area with the butyl rubber body and further enhances the shaping effect of the butyl rubber body when it softens and deforms; when the main copper wire is heated, the spiral copper wire increases the contact area with the butyl rubber body, thereby quickly transferring heat and making the temperature of the butyl rubber more uniform, thereby improving the quality of the butyl rubber in cold weather; at the same time, the spherical protrusion and the spiral copper wire form a special micro-undulating structure inside the butyl rubber, which helps to increase the friction and engagement force between the butyl rubber and the bonded object at the micro level, so that the butyl rubber can better adhere to various surfaces during the bonding process, and the bonding strength is improved.
