Polymer cement waterproof paint

Abstract

The invention discloses a polymer cement waterproof paint. The polymer cement waterproof paint is characterized by comprising a liquid material and a powder material in a mass ratio of 1:2. The liquid material comprises the following components in parts by weight: 300 parts of waterproof emulsion, 30 parts of water, 1 part of preservative and 2 parts of defoaming agent. The powder material comprises the following components in parts by weight: 334 parts of cement, 230 parts of quartz powder, 100 parts of heavy calcium carbonate and 2 parts of high efficiency water reducing agent. Compared with the common polymer cement waterproof paint, the components of the liquid material in the paint are improved: the XL-402 waterproof emulsion with equivalent content to the cement is added, so that the waterproof paint obtains favorable physicochemical comprehensive properties which are embodied by the addition of the waterproof emulsion, such as water resistance, alkali resistance, ultraviolet aging resistance and the like, and also maintains favorable stability with low deterioration tendency.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a polymer cement waterproof coating. Background technique [0002] Polymer cement waterproof coating, also known as JS composite waterproof coating, is an organic liquid material composed of polyacrylate emulsion, ethylene-vinyl acetate copolymer emulsion and other polymer emulsions and various additives, and cement, quartz sand, light and heavy It is a kind of two-component, water-based building waterproof coating made of inorganic powder composed of calcium carbonate and other inorganic fillers and various additives through reasonable proportioning and compounding. [0003] The main performance of this kind of polymer waterproof coating is in the aspects of tensile strength, elongation at break, low temperature flexibility, adhesive strength, water impermeability, impermeability, etc.; Conditional treatment can be reflected, such as heat treatment, alkali treatment,...

AI Technical Summary

Problems solved by technology

[0004] The overall performance of the coating is mainly determined by the type of components and the ratio between the components. By properly adjusting the components and the ratio of the components, the overall performance of the coating can be effectively improved; the current polymer cement waterproof coating , its comprehensive performance is usually based on BG / T 23445-2009 as the standard. In the actual application process, its performance can only meet the general construction environment, and it is lacking in working conditions with high environmental requirements, especially for highly humid environments. , high alkaline environment, and ultraviolet environment under high light, the performance of the current polymer cement waterproof coating is not superior
