Abstract

The invention provides self-leveling type II polymer cement waterproof mortar. The mortar comprises Portland cement, a composite hardening accelerator, aggregates, water, polymer and other additives, wherein the composite hardening accelerator comprises the following raw materials in parts by weight: 3 to 6 parts of calcium lime, 2 to 5 parts of sodium sulphate, and 5 to 10 parts of aluminate cement. The mortar solves the durability problem of poor long-term waterproof anti-penetrability performance of common self-leveling motor due to high aluminum cement component content, realizes the self-leveling construction of polymer cement waterproof mortar, and can be applied to various waterproof construction projects, such as toilets, kitchens, roofs, swimming pools and subsurface structures.

Description

technical field [0001] The invention belongs to the field of waterproof mortar, in particular to a self-leveling type II polymer cement waterproof mortar. Background technique [0002] At present, the polymer cement waterproof mortar still adopts the complicated construction method of layering and batching. There are many defects in this construction method: poor flatness, difficulty in guaranteeing construction quality, long construction period, high construction intensity, and low labor efficiency. In addition, the bonding between the mortar surface and the concrete base is poor, and cracks are prone to occur, which reduces the overall impermeability of the structure. [0003] In order to change the traditional construction method and promote the improvement of construction technology and construction quality, it is necessary to introduce self-leveling technology into the preparation and construction of waterproof mortar. However, in order to obtain rapid hardening and e...
