Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.
The invention will be further described with reference to the drawings and specific examples.
Example 1
As shown in fig. 1, the present embodiment discloses a roof water seepage prevention structure, which includes an old roof 1, wherein a polymer cement mortar 2 is arranged on the old roof 1, a polyurethane sealed primer 3 is arranged on the polymer cement mortar 2, a polyurea waterproof coating 4 is arranged on the polyurethane sealed primer 3, and a first yellowing-resistant top coating 5 is arranged on the polyurea waterproof coating 4; the polymer cement mortar 2, the polyurethane sealing primer 3, the polyurea waterproof coating 4 and the first yellowing-resistant surface coating 5 are all arranged in the U-shaped groove 6, and a polyurethane sealant 7 is arranged in the U-shaped groove 6.
As a preferred embodiment, the polymer cement mortar 2 includes cement, aggregate, and an organic polymer that can be dispersed in water. The waterproof and anti-permeability effects are good; the adhesive strength is high, and the adhesive can be integrated with a structure; the corrosion resistance is strong; high humidity resistance, aging resistance and freezing resistance are good; the product is water-based and non-toxic, and meets the requirement of environmental protection. The waterproof and anti-seepage construction method is suitable for waterproof and anti-seepage engineering of all parts of buildings such as outer wall surfaces, roofs, toilet bathrooms, water pools, basements, tunnels, dams, subways and the like.
As a preferred embodiment, the yellowing-resistant topcoat 5 is a flexible two-component polyurethane aliphatic topcoat material. The yellowing-resistant surface coating 5 is made of a flexible double-component polyurethane aliphatic surface coating material, has very good adhesive force with spray polyurea, has excellent ultraviolet resistance and weathering aging resistance, and can ensure the long-term brightness of the color of a roof.
Example 2
As shown in fig. 2, a parapet roofing prevention of seepage water structure, including old roofing 1 and parapet platform 8, be provided with polymer cement mortar 2 on the old roofing 1, be provided with polyurethane on the polymer cement mortar 2 and seal the end and scribble 3, be provided with polyurea waterproof coating 4 on the polyurethane seals the end and scribble 3, be provided with first resistant yellow stain surface coating 5 on polyurea waterproof coating 4, polymer cement mortar 2 polyurethane seals the end and scribbles 3 polyurea waterproof coating 4 first resistant yellow stain surface coating 5 upside all sets up at parapet platform 8 lower extreme, set gradually JS waterproof coating interfacial agent 9, JS waterproof coating 10, second resistant yellow stain surface coating 11 on the parapet platform 8.
The utility model discloses a work progress: cleaning weeds, garbage and loose joint filling mortar in gaps of the roof tiles in cracking and damaged areas of the parapet wall, cleaning loose parts, and then flattening with polymer cement mortar. Coating the cement paste on the treated roof for one time to improve the bonding force with the base surface; after the cement paste is not sticky, the mixed polymer cement mortar 2 is uniformly scraped on the surface of the base layer, and is flattened and smoothed by a trowel, and the thickness is 2 mm. And carrying out wet maintenance after 24 hours of construction, wherein the maintenance time is different according to different temperature conditions, and is preferably 3-5 days at normal temperature. After the polymer cement mortar is cured and dried, the subsequent construction of the polyurethane closed bottom coating 3 can be carried out. Because the concrete is of a porous structure, moisture, alkaline substances and the like in the concrete can seep out along with the change of environmental conditions, and the adhesive force between the polyurea waterproof coating and the base material can be reduced. The polyurethane bottom coating 3 can penetrate into the concrete to plug the micro-pore channels inside, so that the seepage of moisture and alkaline substances is prevented, and the strength of the concrete matrix is enhanced. The base coat is a polyurethane component, and has very good adhesion with the polyurea coating. Therefore, the polyurea waterproof coating material 4 must be undercoated before the construction.
