Abstract

The invention provides a self-leveling type II polymer cement waterproof mortar. The mortar includes: Portland cement, composite hardening agent, aggregate, water, polymer, and other additives, wherein the composite hardening agent is composed of the following raw materials in parts by weight: quicklime 3-6 parts, sodium sulfate 2 ‑5 parts, 5‑10 parts of aluminate cement. Solve the durability problem of ordinary self-leveling mortar due to the high content of high-alumina cement components resulting in poor long-term waterproof and impermeable performance, and realize the self-leveling construction of polymer cement waterproof mortar, which can be applied to various building waterproofing projects, such as toilets and kitchens , roofs, swimming pools, underground structures, etc.

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...
