A kind of non-fire and anti-static cement-based self-leveling mortar and preparation method thereof

Abstract

The application discloses a non-fire and anti-static cement-based self-leveling mortar and a preparation method thereof, and relates to the technical field of building materials. Self-leveling mortar includes the following components in parts by weight: 100-450 parts of cement, 20-70 parts of gypsum, 1-8 parts of ash calcium powder, 10-30 parts of pozzolanic admixture, 200-600 parts of dolomite sand, non-flammable 50-200 parts of filler, 120-250 parts of conductive material, 1-20 parts of water reducing agent, 0.3-1.5 part of retarder, 0.15-2.5 part of cellulose ether, 0.3-1.5 part of early strength agent, 0.3-1 part of defoamer 2.5 parts, expansion agent 1.5-50 parts, rubber powder 10-80 parts, pigment 2-20 parts, anti-settling agent 0.2-7 parts, shrinkage reducer 0.1-5 parts, pure water 200-350 parts. The self-leveling mortar of the present application widens the application range of cement-based self-leveling to non-fire and anti-static ground, and has the advantages of fast construction, fast drying, high flatness, no fire, anti-static, and self-leveling as a surface layer with decorative Good effect.

Description

technical field [0001] The present application relates to the technical field of building materials, more particularly, it relates to a non-fire and anti-static cement-based self-leveling mortar and a preparation method thereof. Background technique [0002] Cement-based self-leveling mortar is a ground material that is composed of cement-based cementitious materials, fine aggregates, fillers and additives. After the self-leveling mortar is mixed with water, it becomes a fluid mortar. After being poured into the ground, the mortar can be automatically leveled, the ground can be automatically leveled, and a high-level base surface can be obtained. The ideal material for paving is also a development direction of modern building ground construction, with great market potential. [0003] Ignition phenomenon refers to the phenomenon of mechanical impact and friction generating sparks, mainly due to the impact and friction of hard objects, the energy loss is less, and the remaini...

AI Technical Summary

Problems solved by technology

[0004] In related design specifications and construction techniques, non-flammable cement mortar is generally used as non-flammable ground surface material, but non-flammable cement mortar itself does not have self-leveling function, and construction is more inconvenient. At the same time, it is directly applied to the ground. The decorative performance is poor; the anti-static floor generally adopts anti-static overhead boards, PVC plastic boards, and epoxy coatings to make the ground have anti-static functions, but the compressive capacity of these products is weaker than that of cement mortar floors, so it cannot meet complex Environmental use requirements

At present, cement-based self-leveling mortars at home and abroad have not been practically applied in the field of non-flammable and anti-static floors, which makes the actual use of cement-based self-leveling mortars very limited.

So far, cement-based self-leveling mortars with non-flammable and anti-static properties have not been developed and sold on the market
