关于聚氨酯屋顶防水涂料施工流程

标签:关于,屋顶,防水,涂料,施工,流程 时间:2024年03月29日 阅读302

1、涂一层底胶:此工序相称于传统沥青屋顶防水施工涂刷冷底子油,其目的是隔断下层潮气,防止屋顶防水涂膜起鼓脱落;加固下层,进步涂膜与下层的粘结强度,防止涂层出现针气孔等缺陷。我公司建议用聚氨酯底胶作为下层处理。
1、bottom coating glue: this process is equivalent to the traditional asphalt waterproofing coating cold primer oil. Its purpose is partition base moisture, and prevent waterproof coating drum off; reinforced grass roots, improve the bonding strength of coating and substrate and to prevent a needle holes and other defects in the coating. I recommend the use of polyurethane as the base of the company to deal with.


聚氨酯底胶的配制:将聚氨酯甲料、乙料按比例1:2~3(重量比)配合(其它涂层按产品规格规定比例配合)。当乙料较稠时,可用专用稀释剂稀释,切不可用含酸性或含油性稀释剂稀释,以免影响原产品质量。在配制时(百度快照优化),应先把乙料稀释搅拌2-3分钟,如不需稀释,可直接用甲乙组分配和搅拌5-10分钟,把搅拌器提起,可见到均匀液体慢慢滑自容器为佳,同时应细致,打开料应马上盖严,以免凝固报废,混合料应根据现实用量,即配即用。

Preparation of polyurethane primer: Polyurethane a material, B, according to the proportion of 1:2 ~ 3 (weight ratio) with (other coating according to the proportion of the product specifications). When the B material is thick, can be diluted with a special diluent, must not be diluted with acid or oily thinner, so as not to affect the quality of the original product. In preparation, should first B material dilution and stir 2-3 minutes, such as the need to dilute, can be directly used in a and B group distribution and stirring for 5 to 10 minutes, lift agitator, visible to the uniform liquid slowly slide from the container is better, meanwhile, attention should be paid to open the material should be immediately cover tightly, so as to avoid solidification scrapped, the mixture should be based on the actual usage, the use of the.


2、局部加强:对伸缩缝、控制缝、阴阳角、管道缝等处,可由一层加筋布加强,固化后再进行整体屋顶防水施工。
2、local reinforcement: the expansion joints, control joints, yin and yang angle, pipe joints and other places, can be reinforced by a layer of reinforced cloth, and then the overall waterproof construction.


3、第一遍涂层施工:在底胶基本干燥固化后,用塑料或橡胶刮板均匀涂刮一层涂料,涂刮时要求均匀同等,不可过厚或过薄,涂刮厚度一样平常为0.8MM左右为宜。开始涂刮时,应根据施工面积大小、外形和用料,同一考虑施工退路和涂刮顺序。
3、the over coating construction: at the end of the gum base drying and curing, a layer of paint scraper with plastic or rubber scraper evenly, scraping requires uniform, not too thick or too thin, scraping thickness is generally about 0.8mm is appropriate. Start scraping, construction should be based on the size, shape and material, to consider a unified retreat and scraping order construction.


4、第二遍涂层施工:在第一遍涂层基本固化后,再在其外观刮涂第二遍涂层,涂刮方法同第一遍涂层。为了确保屋顶防水工程质量,涂刮的方向必须与第一层的涂刮方向垂直。重涂时间的间隔,由施工时的温度和涂膜固化的程度(以手触不粘)来确定。 

4、Second times the coating construction: in the first pass of the basic curing coating, and then scraping the surface of the coating second times, the coating method with the first coating. In order to ensure the quality of waterproof project, the direction of the coating must be perpendicular to the direction of the first layer. The interval of the coating time is determined by the temperature at the time of construction and the degree of curing of the film (by hand).


5、在第二遍涂膜固化后,再按上述方法涂刮第三遍涂膜。
Second, after the 5.5 times of the film curing, and then apply the method above third times the coating.


6、铺贴保温层或饰面材:在第三遍涂膜施工完毕又未完全固化时,可在其外观稀撒上少量干净的砂粒(直径不大于2MM),以增长涂膜层与将要覆盖的水泥砂浆之间的粘结能力。当涂膜固化完全和检查验收合格后,即可抹水泥砂浆保温层或粘贴面砖、马赛克等饰面层。

6、 shop affixed protective layer and the facing material: in the three times and incompletely cured coating film construction is completed, on the surface of thin and small clean sand (diameter less than 2mm) to the bond capability between the increase the coating layer and will be covered in the cement mortar. When cured film completely and after passing the acceptance inspection, you can wipe cement mortar protective layer or paste tiles, mosaics and other decorative layer.
