Problems solved by technology

[0003] At present, polymer cement waterproof coatings generally adopt the two-component packaging form of liquid material and powder material. When using, the two components are mixed and stirred, and then applied by scraping, brushing or roller coating; This increases the transportation and storage costs of the product, and makes it impossible to realize the multiple utilization of the remaining powder. At the same time, due to the different physical and chemical properties of the two components, it also brings higher requirements to the storage environment.
[0004] In addition, due to the fact that cutting corners and cutting materials often occur in the construction process of home improvement waterproofing projects, some contractors add excessive water to polymer cement waterproofing materials in order to save materials in order to seek to paint a larger area. Destroy the performance of waterproof materials, especially the durability, and bring hidden dangers of leakage to buildings

Abstract

The invention discloses mono-component polymer-cement waterproof mortar which comprises Portland cement, redispersible latex powder, cellulose ether, water reducers, defoamers, quartz sand and quartz powder. The mono-component polymer-cement waterproof mortar adopts a mono powder packaging form and is stirred uniformly with water in different quantities when used so as to obtain the mortar different in thickness, thereby being applicable to construction modes of blade coating with a scraper, brush coating with a brush and roll coating with a roller and applicable to water proofing of bathrooms, kitchens, balconies and the like in the field of home decoration water proofing. The waterproof mortar has excellent waterproof performance, can be constructed on moist bases and is high in cementing bond with the bases, resistant to water, heat and alkali and environment-friendly without volatilization of toxic and harmful gases.

Description

technical field [0001] The invention relates to a single-component polymer cement waterproof slurry, which belongs to the field of building materials. Background technique [0002] In recent years, in waterproofing projects in the field of home improvement, polymer-modified cement-based waterproofing coatings have been used in waterproofing projects with an increasing proportion year by year due to their excellent waterproof performance and excellent environmental protection characteristics. This kind of waterproof slurry is generally water-based slurry, which can be directly applied on the wet base, which is more demanding than oil-based waterproof coatings such as polyurethane and asphalt for the base. On the other hand, polyurethane, asphalt and other waterproof coatings need to carry out interface treatment and protective layer work after waterproofing construction and before veneering brick process, which increases the project cost. The polymer cement waterproof slurry...
