Roof waterproof construction process

Abstract

The invention discloses a roof waterproof construction process which comprises the following steps of 1, cleaning a roof; 2, repairing and smoothening the surface layer of the roof; 3, coating ethyl acrylate glue onto the surface layer of the roof in the step 2 in a rolling way, and then flatly laying a layer of glass fiber gridding cloth; 4, diluting and uniformly proportioning modified calcium carbonate powder, polyurethane waterproof paint and acetone, and then parallelly coating and scraping the materials onto the surface of the glass fiber gridding cloth by a plastic scraper; 5, performing second time of vertical coating and scraping on the surface of a coating according to the step 4; and 6, after the curing of the second coating and scraping layer, spraying an organic silicon anti-aging agent onto the surface, and performing drying. The roof waterproof construction process has the advantages that construction bubbles do not exist in the construction layer and the roof by using the process; the bonding is firmer; and the construction layer has a low thermal expansion and cold contraction rate, cannot easily bulge and cannot easily tilt.

Description

technical field [0001] The invention relates to the field of building waterproof engineering, in particular to a roof waterproof construction [0002] Craftsmanship. Background technique [0003] The problem of building roof penetration is a relatively common quality problem in buildings, and it is also the most intense problem reported by users. Many residents often experience roof water seepage, water leakage, and large-scale peeling of the interior wall paint layer after use. Over time, the leaking and damp walls will also develop mildew, which directly affects the health of residents. Offices, computer rooms Long-term leakage in workplaces, workshops and other workplaces will seriously damage office facilities, precision instruments, machine tool equipment, etc., and even cause short circuits in electrical equipment. It can be seen that good waterproofing works occupy a very important position in construction projects. [0004] At present, the waterproof treatment meth...

Problems solved by technology

[0004] At present, the waterproof treatment methods of building roofs in my country have gradually changed from the methods of laying felt paper and tar asphalt in the 1970s and 1980s to the methods of laying modified asphalt waterproof membranes and EPDM polymer waterproof membranes, but there are still the following Problems: 1. Poor high and low temperature resistance, asphalt is easy to melt when it encounters high temperature, and it is easy to crack when encountering low temperature asphalt; 2. It is easy to bulge and warp, and linoleum paper and waterproof membranes absorb high heat, especially in summer when high temperature and strong After ultraviolet radiation, thermal expansion and contraction are prone to occur, resulting in warped skin and bulging; 3. It is easy to age and flammable; 4. The construction is complicated and the construction period is long
