High performance antistatic self-leveling mortar

Abstract

The invention discloses high-performance antistatic self-leveling mortar. The high-performance antistatic self-leveling mortar is prepared from the following raw materials in parts by weight: 55 to 80parts of portland cement, 5 to 10 parts of sulphoaluminate cement, 10 to 15 parts of re-dispersible latex powder, 10 to 13 parts of fly ash, 0.35 to 1.5 parts of polypropylene fiber, 2 to 5 parts ofultrafine ettringite, 0.1 to 0.2 part of a water reducing agent, 0.1 to 0.2 part of an early strength agent, 0.15 to 0.3 part of a retarder, 0.15 to 0.3 part of a thickener, and 50 to 100-mesh waste polystyrene sheet broken particles. The high-performance antistatic self-leveling mortar has good fluidity, self-flow leveling, no need for vibration, simple construction, water addition, pumping pouring, and quick spreading; the mortar is wear-resistant and anti-cracking, smoothing in surface, fast and convenient in construction, has high hardening strength on the ground, excellent antistatic andwaterproof performance, can be made into colored ground of different colors, and is environmentally-friendly easy-to-operate self-leveling mortar.

Description

technical field [0001] The invention belongs to the technical field of mortar production, in particular to a high-performance antistatic self-leveling mortar. Background technique [0002] At present, most of the cement self-leveling materials used in the market are epoxy floor materials. After the application of this material, there are many problems in terms of moisture resistance, high temperature resistance, UV resistance, brittleness, medium corrosion resistance, light pollution, etc. , leading to limitations in the construction and use process, especially in some areas with high requirements for floor materials, its shortcomings are more obvious. [0003] Cement-based self-leveling mortar has good fluidity and stability, high early strength, fast construction speed, and low labor intensity, but the cement self-leveling mortar currently on the market mainly has the following problems: (1) Early Low strength, which affects the construction process and the time when the ...

[0002] At present, most of the cement self-leveling materials used in the market are epoxy floor materials. After the application of this material, there are many problems in terms of moisture resistance, high temperature resistance, UV resistance, brittleness, medium corrosion resistance, light pollution, etc. , leading to limitations in the construction and use process, especially in some fields with high requirements for floor materials, its shortcomings are more obvious

[0003] Cement-based self-leveling mortar has good fluidity and stability, high early strength, fast construction speed, and low labor intensity, but the cement self-leveling mortar currently on the market mainly has the following problems: (1) Early Low strength, which affects the construction process and the time when the project is put into use; (2) The surface flatness of the mortar is not enough, and it is easy to produce surface sanding, peeling, hollowing, etc.; (3) Insufficient wear resistance; (4) Mortar hardening Afterwards, it is easy to shrink and crack;
