Abstract

The invention relates to a cement-based self-leveling mortar, and more particularly relates to a macromolecular adhesive cement. The macromolecular adhesive cement comprises the components in parts by weight: 80-100 parts of water-borne epoxy resin, 16-20 parts of water-borne epoxy curing agent, 120-150 parts of complex portland cement, 30-50 parts of quartz silt powder, 10-15 parts of water, 35-50 parts of pigments and fillers, 0.3-0.5 parts of wetting dispersant, 2-6 parts of self-leveling additives, and 2-5 parts of water-borne color paste. The macromolecular adhesive cement disclosed by the invention is a single-component, dry-powder-shaped and water-borne self-leveling cement-based hard / soft type waterproof adhesion-blocking and leveling material which is processed via scientific proportioning, integrates the functions of water prevention, adhesion, blockage and leveling, as well as is non-toxic and odorless, and belongs to cement-based macromolecular polymer water-borne dry-powder waterproof mortars.

Description

technical field [0001] The invention relates to a cement-based self-leveling mortar, in particular to a polymer cement. Background technique [0002] The traditional ground leveling construction method is to mix the ordinary cement mortar, then use manual paving, scraping, and plastering. Before the final setting of the mortar, it must complete three times of compaction, pulp extraction, and plastering. This multi-layer construction method has low production efficiency and a large material waste. The most important thing is that its quality is not easy to be guaranteed. After construction, the ground often has quality problems such as sanding, peeling, hollowing, and cracking. Seriously affect the look and feel and use effect of the building surface, become a common quality problem of ordinary cement mortar ground, and have not been effectively cured. As an important part of the building, the quality of the ground has attracted more and more attention. [0003] Cement-...
