Acrylate polymer composite waterproof system and construction method thereof

Abstract

The invention discloses an acrylate polymer composite waterproof system and a construction method thereof. The system comprises a waterproof coating spread on a base layer. The waterproof coating comprises a base adhesive layer sprayed on the base layer, an acrylate polymer waterproof coiled material adhered to the base adhesive layer and a protection layer sprayed on the coil material. The construction method comprises the steps of cleaning the base layer and printing the pink line, spraying the base adhesive layer on the pre-spread location, while the layers being still wet, swiftly spreading the acrylate polymer waterproof coiled material, using a scraper to level wrinkled area, after the spreading of the waterproof coiled materialm drying in natural condition, after the coiled material being solidly glued, spraying the protection layer uniformly on the surface, and airing for 24 hours to complete the construction. The three layers of waterproof structure coordinate with each other, and constitute a highly reliable waterproof system, thus overcoming the functional limitation of a single water proof material. The system has the advantages of being strong in anti-permeation ability and tensile strength, good in low temperature flexibility, small in coefficient of linear expansion, high in adhesive strength, strong in deformation adaptability, and long in service life. The construction method has the advantages of requiring no open fire operation, being convenient for construction and being environment-friendly and the like.

Description

technical field [0001] The invention relates to the field of building waterproofing, in particular to an acrylate polymer composite waterproofing system, and also relates to a construction method of the waterproofing system. Background technique [0002] At present, the waterproof materials used in my country's building waterproof construction are mainly elastomer-modified bitumen waterproof membrane (SBS). This technology is easy to construct and has become the mainstream technology of current waterproof construction, accounting for about 70% of engineering applications. about. The construction method is mainly hot-melt single-layer or double-layer laying, that is, the modified asphalt waterproof membrane is placed on the building base, and the membrane is baked and laid with a liquefied gas flame spray gun to make it baked. Baked until the semi-melted part is bonded to the seam between the roof or the membrane, forming a waterproof layer covering the entire building base, ...

AI Technical Summary

Problems solved by technology

Although elastomer-modified asphalt waterproofing membrane and construction technology are the mainstream products and technologies in the waterproofing industry, they have the following defects: 1. A large amount of harmful gas is produced during the production and construction process, which not only causes serious pollution to the environment but also Harmful to the health of workers; 2. Mainly constructed by high-temperature hot-melt method, which can easily cause fire hazards; 3. Asphalt materials are brittle and cracked at low temperatures, and have poor anti-aging ability; 4. Coiled materials overlap each other during construction It is difficult to bond at the edge and the edge, and lap joints and seams at the edge have become common hidden dangers of water leakage; 5. The coiled material and the base surface cannot be firmly bonded, and it is easy to cause water to flow between the coiled material and the base surface, making it waterproof loss of function
