Problems solved by technology

[0004] Rigid waterproof mortar is used for parts with certain bearing capacity or does not need bearing capacity, and its crack resistance is poor. Most of them implement JC / T 2090-2011 or JC / T 984-2011 standards. Due to the relatively low liquid powder in the prior art, The humidity is low, and the wetting effect on the construction base surface is poor. The construction personnel need to wet the construction base surface with water before use. Therefore, the existing technology mainly adopts the method of brushing for construction, and sometimes even batch scraping construction is required. , not suitable for a variety of construction situations, and the construction efficiency is also greatly reduced

Abstract

A polymer cement waterproof mortar, comprising a liquid material component and a powder material component, the liquid material component includes tertiary vinegar emulsion, and the powder material component includes cement, filler, 40-70 mesh sand, 71-140 Mesh sand, the cement is greater than or equal to 200 mesh, the filler is greater than or equal to 600 mesh, the tertiary vinegar emulsion includes emulsion particles of greater than or equal to 200nm and less than or equal to 300nm, sand, cement, filler and emulsion particles form continuous particles Grading. The invention has good wettability, without pre-wetting the construction base surface, and there is no obstacle when the roll coating is applied to the dry base surface of the silicon-calcium board; the continuous particle gradation makes the mortar can be rolled evenly, and the roll coating During the process, the mortar is easy to push away, the coating is more uniform and smooth, and a more excellent construction effect is achieved. While improving the construction effect, it reduces labor costs and time costs, which is of great significance for the construction of waterproof mortar.

Description

technical field [0001] The invention belongs to the technical field of chemical coatings, in particular to a polymer cement waterproof mortar. Background technique [0002] Polymer cement waterproof mortar is made of cement and fine aggregate as the main materials. It is mainly used for the repair or anti-seepage treatment of building roofs and internal and external wall leakage, and the waterproof and anti-seepage of various pools and swimming pools. The application of polymer modified cement waterproof mortar has a history of more than 60 years. Different from the traditional cement-based hydraulic waterproof material, it becomes a double binder system through polymer modification and forms a complementary It has the advantages of high bonding strength, convenient construction, corrosion resistance, high temperature resistance and aging resistance. Polymer modified cement waterproof mortar can be divided into one-component mortar and two-component mortar. According to dif...
