Problems solved by technology

Moreover, the elongation at break of traditional roof waterproof coatings, caulking pastes, and coiled edge pastes is generally not large, and it is easy to crack and leak due to deformation of the base surface when it is applied to some roof structures with many expansion joints and deformation joints. , which greatly affects the quality of the project
However, after the ordinary silicone caulk is caulked, the waterproof coating cannot be effectively attached to it, and it is difficult to repair
[0003] There are also patent documents disclosing the use of pure acrylic emulsion, neoprene emulsion, silicone waterproofing agent, etc. as a technical solution for metal roof heat insulation and waterproof coatings, but its elongation at break, UV resistance and long-term water resistance are insufficient, and The heat-insulating and waterproof coating described above is only suitable for metal roofs, and the applicable field is relatively narrow

Abstract

The invention discloses a high-elastic weather-resistant waterproof sealing material for a roof and a preparation method of the high-elastic weather-resistant waterproof sealing material. The high-elastic weather-resistant waterproof sealing material is prepared from the following components: 20-45% of pure acrylic emulsion, 5-20% of neoprene latex, 1-10% of tackifier emulsion, 15-40% of pigment and filler, 1-20% of water and 2-5% of other additives. The high-elastic weather-resistant waterproof sealing material does not need to cover a protection layer, the water resistance and the weather resistance are high, the strength is high, and the elongation at break is high; the sealing material is bonded with most substrates of an existing roof system well, and the surface of the sealing material is covered with a traditional waterproof anticorrosive paint, so that effective adhering is realized, the sealing material is easy to maintain and coat again; and the sealing material can be used as an exposed roof waterproof paint as well as a caulking compound, a node sealing compound and a rolled material edge sealing compound.

Description

technical field [0001] The invention relates to the field of waterproof materials, in particular, the invention relates to a high-elastic weather-resistant roof waterproof sealing material and a preparation method thereof. Background technique [0002] In the roof waterproof sealing system, the materials used are generally waterproof coiled materials, waterproof coatings, edge banding pastes, and caulking pastes, etc., while traditional waterproof coiled materials, waterproof coatings, coiled material edge banding pastes, and caulking pastes are generally not weather-resistant. So after the waterproof seal is done, it is necessary to make a protective layer. Moreover, the elongation at break of traditional roofing waterproof coatings, caulking pastes, and coil edge sealing pastes is generally not large. When applied to some roof structures with many expansion joints and deformation joints, it is easy to crack and leak due to deformation of the base surface, resulting in repa...
