The waterproof paint is generally divided into asphalt-based waterproof paint, high polymer modified asphalt waterproof paint and synthetic high polymer waterproof paint (polyurethane and acrylic acid), and the waterproof paint is generally used for waterproof of kitchens, toilets, wall surfaces and floors.
At present, because of the limitation of waterproof construction technical conditions, consumers generally tend to select acrylic acid and polyurethane as bathroom waterproof paint, but the following defects exist in both acrylic acid and polyurethane: the first one requires 2-3 times of film curing process, generally requires 3-4 days of construction period, including base layer treatment, internal corner chamfering treatment, base layer leveling and hardening, and consumes a great deal of manpower, materials and the like; secondly, the coating film-forming waterproof is required to be dried and flattened for a base layer, and hard objects such as sand and stone are required to be prevented from being broken after film-forming, so that a cement mortar protective layer is required to be sprayed after waterproof film-forming curing, and then ceramic tiles are paved; thirdly, in the actual hydropower construction engineering case of kitchen and bathroom, a water pipe (mainly ground water is used for running and the ground is used for cutting grooves are connected) is often paved, then waterproofing is carried out, so that waterproof coating is difficult to construct from the bottom of the water pipe, and in the actual waterproofing construction process, the water pipe is often arranged below a ground waterproof layer, and the waterproofing can only prevent daily water but cannot prevent the risk of water leakage of the water pipe.
CN 209443595U discloses a thin indoor waterproof protective layer structure, the waterproof protective layer is composed of a structural layer, a leveling layer, a waterproof layer, a protective layer and a decorative surface layer, wherein the structural layer at the bottom end is a reinforced concrete floor slab, the leveling layer is positioned above the structural layer, and the waterproof layer is positioned between the leveling layer and the protective layer; the protective layer is positioned between the waterproof layer and the decorative surface layer and is composed of bonding mortar and glass fiber mesh cloth, a plurality of mutually parallel protruding edges are arranged on the lower bottom surface of the decorative surface layer, the protruding edges are embedded into the protective layer, and a plurality of anti-slip bulges are arranged on the upper end surface of the decorative surface layer. The structure disclosed by the patent is positioned above a building water pipe, and can only play a role in daily water prevention, but cannot prevent the risk of water leakage of the water pipe.
CN 212078537U discloses an indoor waterproof structure, and it includes first basic unit, first basic unit top is provided with first waterproof layer, first protective layer and screed-coat, first waterproof layer with first protective layer sets gradually from bottom to top. In addition, an additional waterproof layer, a structural layer, a backfill layer and a bonding layer are also arranged. Although the waterproof structure disclosed by the patent relates to the waterproof structure around the floor drain, the waterproof structure still cannot meet the requirement that when a water pipe leaks, the waterproof effect is achieved on a building, the whole structure is complex, and the construction level of workers is tested to a certain extent.
CN 110093989a discloses an indoor waterproof structure, comprising: wall waterproof structure: waterproof structure of the internal corner of the wall surface and the ground; a waterproof structure of a penetrating building; a floor drain outlet waterproof structure; a waterproof structure of a water stop ridge at the lower part of the shower room partition; a waterproof structure of a water stop ridge at the lower part of the threshold stone; a waterproof structure of a water stop ridge at the lower part of the bathtub; a water supply pipe orifice waterproof structure; waterproof structure of toilet with floor heating; the water-proof structure of the same-layer drainage toilet; and a waterproof structure for stopping the water from the side of the curtain wall in the bathroom. The patent aims at different construction positions to carry out different waterproof construction, although the risk of water leakage caused by water pipe breakage can be prevented, different waterproof structures are needed for different construction positions, so that the construction difficulty is increased, and waterproof failure caused by construction reasons is easier to occur.
Based on the above-mentioned prior art's condition, there are indoor waterproof coating construction cycle in the prior art long, the construction degree of difficulty is high, waterproof material is not able to bear with a bump after the construction, waterproof material can not prevent building structure ground below water pipe from leaking, current waterproofing membrane is not suitable for indoor or construction of structure complex department again wait to need to solve technical problem.
