Problems solved by technology
[0002] At present, the existing waterproof rolls cannot be closely adhered to wet bases and uneven bases with construction defects, which seriously plagues the progress of building waterproofing technology.
As we all know, it is difficult to provide a dry base and a high-level base on the construction site, especially the construction of underground projects, which is often constructed in a humid environment and plastered unevenly, resulting in the construction of hot-melt coils and self-adhesive coils. Difficult, the coil and the base layer cannot be bonded or bonded weakly, resulting in hollowing, making the waterproofing of underground projects ineffective, and becoming a difficult problem for building waterproofing

[0023]
[0024] Wherein, the water-based epoxy resin is bisphenol A epoxy resin, preferably 6101 type.
[0025] The polyamide resin (preferably phenalkamine, more preferably phenalkamine curing agent T31), epoxy acrylate resin and water-based emulsion system can be cured on a wet base, and are non-toxic and environmentally friendly product.
[0026] The water-based epoxy acrylic acid is an epoxy resin modified by acrylic acid, which can be used as a temperature-resistant component, that is, an acrylic acid-modified epoxy resin is added when there is a temperature-resistant requirement; the water-based epoxy acrylic acid is preferably methacrylic acid epoxy resin.
[0027] The dioctyl phthalate, dibutyl phthalate, chlorinated paraffin, nonylphenol polyoxyethylene ether, and octylphenol polyoxyethylene ether are used a...

The invention discloses a waterproof coil system capable of being constructed on a humid and uneven base course. The waterproof coil system comprises a bond waterproof course arranged on a concrete base course and a waterproof coil adhered to the bond waterproof course, wherein the bond waterproof course is formed by mixing a liquid material, a powder material and a curing agent, wherein the liquid material comprises 8-12 parts of water-borne epoxy resin, 10-15 parts of VAE emulsion, 1-5 parts of water-borne epoxy acrylic resin and 2-5 parts of methyl triethoxysilane; and the powder material comprises 15-25 parts of R-type Portland cement, 8-18 parts of quartz powder, 1-2 parts of sodium hexametaphosphate, 1-3 parts of calcium methyl sulfate, 2-5 parts of calcium carbonate and 1-3 parts of fumed silica. The compound waterproof system can be used for bonding a waterproof coil on a humid base course and an uneven base course, and the bond waterproof course has an effect on bonding a waterproof coil and also an effect of an additional elastic waterproof course, so that the system has excellent waterproof performance and has an extremely strong bonding force with a concrete base material and deformation resistance.
Description
technical field [0001] The invention belongs to the technical field of building waterproofing, and relates to a waterproof material, in particular to a waterproof coiled material system that can be constructed on wet and uneven bases. Background technique [0002] At present, the existing waterproof membranes cannot be tightly adhered to wet bases and uneven bases with construction defects, which seriously plagues the progress of building waterproofing technology. As we all know, it is difficult to provide a dry base and a high-level base on the construction site, especially the construction of underground projects, which is often constructed in a humid environment and plastered unevenly, resulting in the construction of hot-melt coils and self-adhesive coils. Difficult, the coiled material and the base layer cannot be bonded or the bond is not strong, resulting in hollowing, making the waterproofing of underground projects ineffective, and becoming a difficult problem in bu...
