Description

Technical Field

[0001] This invention relates to the field of waterproof membrane technology, specifically to a self-protecting polymer self-adhesive waterproof membrane with Velcro. Background Technology

[0002] As the core barrier between the building's underground structure and the external soil and groundwater, the reliability of the waterproofing of basement exterior walls directly determines the safety and structural durability of the underground space. Because the underground environment is constantly damp and must withstand multiple forces, including soil lateral pressure, groundwater pressure, and external forces during backfilling, extremely high requirements are placed on the adhesion, bonding stability, and resistance to damage of the waterproofing membrane. In long-term construction practice, the selection of waterproofing membrane and the construction process have always been key factors restricting the quality of basement exterior wall waterproofing, and both traditional and current mainstream technologies have inherent, unavoidable defects.

[0003] For a long time, hot-melt modified bitumen waterproof membranes have been the main technical solution for waterproofing basement exterior walls. These membranes are widely used due to their wide availability and high initial bonding strength. However, the inherent limitations of side wall construction lead to several significant quality risks. Firstly, the narrow space and vertical working surface of side wall construction make it difficult to achieve full adhesion between the membrane and the substrate using the hot-melt process. Uneven heating in some areas can result in weak adhesion, leading to large-area delamination and hollowing. Secondly, hot-melt membranes have high density and heavy weight per unit area. After vertical installation, they rely solely on initial adhesion and a few fasteners for support, making them prone to sagging and detachment during and after construction. More seriously, during subsequent backfilling, the significant lateral and downward forces generated by the settling of the backfill soil directly act on the membrane surface, causing the installed membrane to completely separate from the underground structural layer, resulting in a two-layer structure between the waterproofing system and the structural layer.

[0004] While self-adhesive waterproof membranes have greatly improved the construction problems of the aforementioned hot-melt membranes, they have also brought new issues. For example, they have insufficient temperature resistance; during summer construction or when underground temperatures rise, the adhesive layer is prone to softening and flowing, causing the membrane to slip on vertical walls. This is especially true at stress concentration points such as corners, where slippage can easily lead to membrane stacking or tensile cracking, disrupting the continuity of waterproofing. Furthermore, the adhesive layer of self-adhesive waterproof membranes lacks bonding durability; in long-term exposure to damp underground environments, the bonding strength of the adhesive layer gradually weakens, and under long-term soil lateral pressure, there is still a risk of localized debonding.

[0005] Therefore, it is necessary to develop a polymer self-adhesive waterproof membrane with excellent temperature resistance. Summary of the Invention

[0006] This invention proposes a self-protective polymer self-adhesive waterproof membrane with Velcro, which solves the problem of insufficient temperature resistance of polymer self-adhesive waterproof membranes in related technologies.

[0007] The technical solution of this invention is as follows: This invention proposes a self-protective polymer self-adhesive waterproof membrane with hook and loop fasteners, which, from bottom to top, sequentially includes an anti-adhesive layer, a lower high-temperature resistant and crack-resistant reactive adhesive layer, a high-strength reinforcing layer, an upper high-temperature resistant and crack-resistant reactive adhesive layer, a hook and loop fastener layer, and a hook and loop fastener layer. The lower high-temperature resistant and crack-resistant reactive adhesive layer and the upper high-temperature resistant and crack-resistant reactive adhesive layer each independently include the following raw materials in parts by weight: 35-45 parts asphalt, 8-15 parts softener, 2-7 parts styrene-butadiene block copolymer, 1-5 parts solution-polymerized styrene-butadiene rubber, 1-5 parts tackifier, 8-15 parts rubber powder, 0.1-0.6 parts organic fiber, 0.5-2 parts compatibilizer, and 15-30 parts filler. The solution-polymerized styrene-butadiene rubber is composed of a first solution-polymerized styrene-butadiene rubber and a second solution-polymerized styrene-butadiene rubber, and the styrene content of the first solution-polymerized styrene-butadiene rubber and the second solution-polymerized styrene-butadiene rubber is different.

[0008] As a further technical solution, the hook and loop surface layer has an 8-15cm release film on one side to connect with it to form a 6-10cm overlap edge, preferably 8cm. The hook surface layer and the looped yarn layer have the same width, both 90-95cm, preferably 90cm.

[0009] As a further technical solution, the hook and loop layer is made of synthetic fiber materials such as nylon and polyester, and hooks with a height of 0.2~1.5mm are evenly distributed on the surface of the hook and loop layer; the loop layer is made of synthetic fiber materials such as nylon and polyester, and its surface has a uniform loop surface without obvious unevenness, with a height of 0.1~2mm.

[0010] As a further technical solution, the upper high-temperature resistant and crack-resistant reactive adhesive layer and the lower high-temperature resistant and crack-resistant reactive adhesive layer have the same composition, and the thickness of the upper high-temperature resistant and crack-resistant reactive adhesive layer and the lower high-temperature resistant and crack-resistant reactive adhesive layer are each independently 0.4~0.8mm.

[0011] As a further technical solution, the particle size of the rubber powder is 40-60 mesh, and the rubber powder is fine tire rubber powder.

[0012] As a further technical solution, the filler is heavy calcium carbonate powder.

[0013] As a further technical solution, the styrene content of the first solution-polymerized styrene-butadiene rubber is 20wt%, and the styrene content of the second solution-polymerized styrene-butadiene rubber is 45wt%.

[0014] This invention relates to a self-protective polymer self-adhesive waterproof membrane with Velcro, in which a first solution-polymerized styrene-butadiene rubber (SBR) and a second solution-polymerized SBR with different styrene content are added to the lower and upper high-temperature resistant and crack-resistant reactive adhesive layers. The first solution-polymerized SBR has a lower styrene content, and its molecular chain is mainly composed of flexible butadiene segments with only a small amount of rigid benzene ring structures. This allows it to form a flexible continuous phase, giving the adhesive layer excellent low-temperature flexibility. The flexible butadiene segments can still maintain good molecular chain mobility, preventing the adhesive layer from undergoing a glass transition and making the adhesive layer less prone to cracking when bent or stretched at low temperatures. The second solution-polymerized SBR has a higher styrene content, which can form a rigid supporting skeleton, improving high-temperature stability. This allows the adhesive layer to maintain good cohesion at high temperatures, preventing the membrane from slipping.

[0015] As a further technical solution, the mass ratio of the first solution-polymerized styrene-butadiene rubber to the second solution-polymerized styrene-butadiene rubber is 1:1~2.

[0016] As a further technical solution, the organic fiber is a polypropylene fiber, which is composed of polypropylene short bundles and polypropylene mesh fibers in a mass ratio of 2 to 3:1.

[0017] This invention relates to a self-protective polymer self-adhesive waterproof membrane with Velcro, in which polypropylene fibers are added to both the lower and upper high-temperature resistant and crack-resistant reactive adhesive layers. These polypropylene fibers consist of chopped polypropylene bundles and woven polypropylene mesh fibers. The chopped polypropylene bundles are discretely distributed, forming a skeletal support within the adhesive layer to disperse the concentrated damage caused by puncture force. The woven polypropylene mesh fibers form a continuous network through an interwoven structure, blocking the penetration path of the puncture and delaying crack propagation. Together, these two components ensure local impact resistance at the puncture point and enhance the overall tear resistance, ultimately significantly improving the puncture resistance of the self-protective polymer self-adhesive waterproof membrane with Velcro.

[0018] As a further technical solution, the high-strength tire carcass layer includes one of PE tire, PET tire, PE / PET composite tire and glass fiber reinforced polyester tire carcass layer, and the thickness of the high-strength tire carcass layer is 0.1~0.3mm.

[0019] As a further technical solution, the anti-adhesion layer includes one of the following: a silicone-coated release membrane, a composite geotextile, and mineral granules.

[0020] As a further technical solution, the width of the anti-adhesive layer is 90~95cm, preferably 90cm, and the thickness is 0.5~1.2mm, preferably 0.7mm.

[0021] As a further technical solution, the raw materials of the composite geotextile include PE film and needle-punched nonwoven fabric.

[0022] As a further technical solution, the softener includes one or more of the following: linear oil, naphthenic oil, and aromatic oil.

[0023] As a further technical solution, the compatibilizer is maleic anhydride-grafted polypropylene.

[0024] As a further technical solution, the tackifier includes one or more of hydrogenated petroleum resin, hydrogenated terpene resin, and rosin resin.

[0025] As a further technical solution, the preparation method of the adhesive materials for the lower high-temperature resistant and crack-resistant reactive adhesive layer and the upper high-temperature resistant and crack-resistant reactive adhesive layer includes the following steps:

[0026] S1. Take 1 / 10 of the asphalt and melt-shear it, then add the organic fiber and compatibilizer, and swell it after a second shearing to obtain mixture A;

[0027] S2. Mix the remaining asphalt and the softener, heat to 140~160℃, add the solution-polymerized styrene-butadiene rubber, grind, raise the temperature to 160~180℃, add the styrene-butadiene block copolymer, grind again, raise the temperature to 185~200℃, add the rubber powder and the tackifier, stir, add the filler, cool to 150~175℃, and mix to obtain mixture B;

[0028] S3. Mix the mixture A and the mixture B evenly to obtain the adhesive materials for the lower high-temperature resistant and crack-resistant reactive adhesive layer and the upper high-temperature resistant and crack-resistant reactive adhesive layer.

[0029] As a further technical solution, in step S1, the shearing temperature is 150~165℃, the shearing rate is 1500r / min, and the shearing time is 10min.

[0030] As a further technical solution, in step S1, the temperature of the secondary shearing is 150~165℃, the shearing rate is 3000r / min, and the shearing time is 30min.

[0031] As a further technical solution, in step S1, the swelling temperature is 150°C and the swelling time is 2 hours.

[0032] As a further technical solution, in step S2, the grinding time is 10-20 minutes, the secondary grinding time is 10-30 minutes, and the stirring time is 1-2 hours.

[0033] As a further technical solution, in step S3, the mixing temperature is 150~175℃.

[0034] The working principle and beneficial effects of this invention are as follows:

[0035] In this invention, a self-protecting polymer self-adhesive waterproof membrane with hook and loop fasteners is designed with a hook and loop layer and a loop fastener layer, making it extremely easy to fix to the basement exterior wall during construction, achieving full adhesion and greatly improving work efficiency. Furthermore, different amounts of first and second solution-polymerized styrene-butadiene rubbers with varying styrene content are added to the raw materials of the lower and upper high-temperature resistant crack-resistant reactive adhesive layers. These two components work synergistically to form a uniform and stable blend system. The rigid support structure formed by the high-styrene-content component interweaves with the flexible segments of the low-styrene-content component, allowing the adhesive layer to maintain its deformation resistance at high temperatures and its flexible adhesion at low temperatures over a wide temperature range, thus improving the temperature resistance of the self-protecting polymer self-adhesive waterproof membrane with hook and loop fasteners.
