However, the waterproof roll still has some defects which are difficult to overcome in the practical application process, and the hidden trouble of water leakage is easily generated due to improper construction. At present, all domestic waterproof coiled materials are manufactured and molded in factories, then are transported to a large construction site, and are directly paved, but a plurality of problems exist, wherein the main problems are the following aspects.
1. Poor deformability and loose adhesion
The traditional waterproof roll has certain mechanical strength, particularly, the roll with larger thickness has high mechanical strength and poorer conformability. When in site operation, hollowing is easily formed at the concave and convex corners, the special-shaped structures and the uneven parts of the base layer, and the hidden trouble of water leakage is generated.
2. The lap joint edge part of the coiled material has weak waterproof capability
When traditional waterproofing membrane construction installation, because material nature innate character, the overlap joint limit can't avoid producing when different space coiled material connect. Especially in large-scale construction sites, the construction area of coiled materials is large, the consumption of the coiled materials is large, and the number of the overlapping edges is large, so that the treatment difficulty of the overlapping edges is large, and the hidden danger of water leakage is easy to generate. Such as high polymer (SBS/APP) modified asphalt waterproof coiled material, welding leakage or welding impermeability is easy to generate; the lap joint edges of the self-adhesive polymer modified asphalt waterproof coiled material are not tightly bonded due to the pollution of steam and dust; and the cement-based binder of the wet-laid waterproof coiled material is not fully cured, and the like. Therefore, when the coiled material products are constructed and installed, the waterproof capacity of the overlapping part is weak, and the common problem of the coiled material products is always the large hidden danger of water leakage.

When the specially designed reinforced matrix layer surface is coated with the waterproof coating, the reinforced matrix layer of the porous structure can adsorb the coating, if the material consumption is insufficient and the thickness is not enough, the strong adsorption of the reinforced matrix layer can cause uneven lines on the surface of the coating layer, and at the moment, the coating thickness is indicated to be too thin; and if the surface of the coating layer is still full and smooth after the reinforced carcass layer is fully soaked, the thickness is indicated to meet the requirement. Therefore, through the special design of enhancing the structure of the carcass layer and the leveling property of the waterproof coating, the problem that the thickness of the traditional waterproof coating is difficult to control is solved.
The sheath-core composite long fiber anti-tear cloth has the advantages of high modulus, high thermal stability, high porosity, good wettability with coating, high bonding strength between the sheath-core composite long fiber and a sizing material layer and the like, and can greatly improve the nail stem tear resistance and the high-temperature dimensional stability of the currently-manufactured coiled material, thereby effectively ensuring the waterproof performance and the service life of the currently-manufactured coiled material.
Therefore, the prepared coiled material effectively combines the advantages of the traditional waterproof coiled material and the traditional waterproof coating, and also makes up the defects of the traditional waterproof coiled material and the traditional waterproof coating.
2. The construction is convenient and flexible.
The coiled material manufactured on site is convenient to construct and strong in adaptability. During construction, a cold construction mode is adopted, the requirement on the dry and wet degree of a base layer is not high, construction can be carried out without clear water, and construction can be carried out by manual brushing or mechanical spraying. Even if the base surface is uneven or the structure is complex (such as a special-shaped roof), no hollowing is generated in the construction process.
Meanwhile, the coil stock manufactured on site is flexible to use. The reinforced material with different performance characteristics and different specifications (such as thickness, porosity and the like) can be flexibly selected as the main reinforced layer according to different engineering characteristics.
3. The multilayer reinforced carcass layer is compositely superposed, so that the waterproof layer structure is more scientific and the performance is more excellent.
When the coil is constructed on site, the number of layers of the reinforced carcass layer can be increased, so that the waterproof layer contains two or more layers of reinforced materials. Has the advantages that:
the physical and mechanical properties of the waterproof layer are stronger: under the composite superposition and reinforcement effect of the multilayer reinforced carcass layer, the physical and mechanical properties of the waterproof layer are superposed and reinforced. Compared with the traditional multi-coiled material construction, the method has the advantages of simple process, no lap joint edge, no stranding of the male and female corners and the like. Meanwhile, the sizing material layers are made of the same material, the compatibility is good, the problem of untight interlayer adhesion in construction similar to multiple coiled materials is solved, and the integrity of the waterproof layer is good.
Meanwhile, after the layer of waterproof material is paved, the waterproof coating and/or the reinforced matrix layer can be coated for one time or multiple times as required, namely, the waterproof coating and the reinforced matrix layer are coated alternately in a building block lap joint mode.
Traditional coating need compromise the water-proof effects of self again because of having not enough such as thick coating bulge, package thick liquid, fracture, often need the multichannel to apply paint with a brush or the spraying just can reach required waterproof layer thickness, has time interval between the multichannel coating, leads to layering between the coating easily.
The traditional waterproof coating is coated or sprayed on a base surface, a seamless waterproof coating layer is formed after curing, the waterproof coating layer has good adhesion and sealing performance with the base surface, but the coating thickness of the coating is difficult to control uniformly, waterproof weak points are easy to appear at a thin part of the coating, the coating often needs to be coated or sprayed for multiple times to reach the required waterproof layer thickness, time intervals exist among multiple times of coating, layering among the coatings is easy to cause, particularly, the coating is coated on a construction base surface and only forms a unitary structure, the anti-cracking effect is poor, and water leakage is easy to cause due to damage along with the crack circulation motion of the base layer.
The waterproof coating provided by the invention can meet the requirements of no bulging, no slurry coating, no cracking and integral dry and solid of thick coating. Therefore, the construction steps of brushing the waterproof coating and laying the reinforced matrix layer can be continuously carried out, and one-step forming can be carried out without waiting for drying and solidifying the multiple layers of waterproof coatings after brushing, so that the construction time is greatly simplified.
The waterproof layer has strong anti-cracking capability: adopt the multilayer to strengthen the freshly-made coiled material that the matrix layer stack was strengthened, because the sizing material layer has the creep characteristic, when basic unit fracture produced the displacement, upper and lower two-layer matrix layer because the atress is inconsistent under the cushioning effect of sizing material layer, the displacement is asynchronous, and stress can in time release. Therefore, in the existing coiled material waterproof layer reinforced by the superposition of the multiple layers of reinforced carcass layers, when the base layer cracks, the stress and displacement of the waterproof layer can be released layer by layer from bottom to top, and the waterproof layer has strong cracking resistance.
4. The product is safe and environment-friendly: when the coiled material is constructed on site, toxic and pungent odor gas is not volatilized, and meanwhile, the construction can be finished by adopting a cold construction mode without heating.
