Description

Technical Field

[0001] This utility model relates to the field of waterproof membrane technology, specifically a pre-composite waterproof membrane. Background Technology

[0002] Waterproofing is essential in building construction, and it requires a variety of materials, mainly categorized as asphalt-based waterproofing materials, rubber and plastic waterproofing materials, cement-based waterproofing materials, metal waterproofing materials, and waterproof membranes. Among these, waterproof membranes are essential. Waterproof membranes are mainly used in building walls, roofs, tunnels, highways, landfills, and other areas to resist external rainwater and groundwater seepage. They are flexible building materials that can be rolled up.

[0003] Existing waterproof membranes typically have poor adhesion, making them prone to detachment from the adhesive area, and they also have poor tear resistance, easily tearing and breaking. Therefore, they do not meet current requirements. To address this, we propose a pre-composite waterproof membrane. Utility Model Content

[0004] The purpose of this utility model is to provide a pre-composite waterproof membrane to solve the problems mentioned in the background art, such as the waterproof membrane generally having poor adhesion, easily falling off from the adhesion point, and poor tear resistance, making it easy to tear and break.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pre-composite waterproof membrane, comprising a membrane body, wherein the interior of the membrane body comprises, from top to bottom, a protective layer, a waterproof layer, a reinforcing layer, a reactive adhesive composite layer, and an isolation layer, wherein the reactive adhesive composite layer is formed by hot-pressing pre-composite of a modified bitumen-based reactive adhesive material and a reinforcing mesh fabric.

[0006] Preferably, the waterproof layer is made of high-density polyethylene, thermoplastic polyolefin, or polyvinyl chloride.

[0007] Preferably, the reinforcing layer is made of polyester mesh fabric, the protective layer is composed of fine sand, mineral particles and PE film with excellent weather resistance, and the isolation layer is made of silicone oil release paper or isolation film.

[0008] Preferably, the roll body is disposed on the surface of the roll roller, and a slidable alignment plate is slidably installed on both sides of the roll roller, with the roll body located between the two alignment plates.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] 1. This utility model, through the combination of a protective layer and an isolation layer, enables the roll material body to be protected, reflect ultraviolet rays and enhance anti-slip ability through the excellent weather-resistant fine sand, mineral particles and PE film, as well as silicone oil release paper or release film when in use. Through the setting of the waterproof layer, the roll material body can provide good waterproof performance through high-density polyethylene, thermoplastic polyolefin or polyvinyl chloride materials when in use.

[0011] 2. By setting a reactive adhesive composite layer, this utility model allows the roll material to be used by first removing the release layer, and then bringing the reactive adhesive composite layer into contact with the area to be bonded. This allows the reactive adhesive composite layer, which is pre-bonded by hot pressing of modified bitumen-based reactive adhesive material and reinforced mesh fabric, to produce good adhesion properties, allowing it to adhere to the bonded area and have good tear resistance.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Please see Figures 1 to 3 One embodiment of this utility model is a pre-composite waterproof membrane, which includes a membrane body 1. The interior of the membrane body 1 includes, from top to bottom, a protective layer 4, a waterproof layer 5, a reinforcing layer 6, a reactive adhesive composite layer 7, and an isolation layer 8. The reactive adhesive composite layer 7 is formed by hot-pressing pre-composite of modified bitumen-based reactive adhesive material and reinforcing mesh fabric.

[0018] By setting the reactive adhesive composite layer 7, when the roll body 1 is used, the release layer 8 is first removed, and then the reactive adhesive composite layer 7 is brought into contact with the position to be bonded. The reactive adhesive composite layer 7, which is pre-composite to the modified bitumen-based reactive adhesive material and the reinforcing mesh cloth by hot pressing, produces good bonding performance, allowing it to adhere to the bonding part and have good tear resistance.

[0019] The waterproof layer 5 is made of high-density polyethylene, thermoplastic polyolefin, or polyvinyl chloride.

[0020] The reinforcing layer 6 is made of polyester mesh fabric, the protective layer 4 is composed of fine sand, mineral particles and PE film with excellent weather resistance, and the isolation layer 8 is made of silicone oil release paper or release film.

[0021] Through the combination of protective layer 4 and isolation layer 8, the roll body 1 can be protected, reflect ultraviolet rays and enhance anti-slip ability by fine sand, mineral particles and PE film with excellent weather resistance and silicone oil release paper or release film when in use. Through the setting of waterproof layer 5, the roll body 1 can provide good waterproof performance by high-density polyethylene, thermoplastic polyolefin or polyvinyl chloride material when in use.

[0022] The roll body 1 is disposed on the surface of the roll roller 2, and the roll roller 2 has a slidable alignment plate 3 on both sides, with the roll body 1 located between the two alignment plates 3.

[0023] When in use, the pre-composite waterproof membrane can protect the membrane body 1, reflect ultraviolet rays, and enhance anti-slip ability through the excellent weather-resistant fine sand, mineral particles, PE film, and silicone oil release paper or release film. Through the setting of the waterproof layer 5, the membrane body 1 can provide good waterproof performance through high-density polyethylene, thermoplastic polyolefin or polyvinyl chloride materials when in use.

[0024] When using the roll body 1, first remove the release layer 8, then bring the reactive adhesive composite layer 7 into contact with the area to be bonded. This allows the reactive adhesive composite layer 7, which is pre-bonded by hot pressing of the modified bitumen-based reactive adhesive material and the reinforcing mesh, to produce good adhesion properties, allowing it to adhere to the bonded area and have good tear resistance.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
