Problems solved by technology

This process also has disadvantages such as complex construction process and poor color layering effect.
[0005] China Invention Patent Application No. 200610086046.5 Mix high-grade cement, yellow sand and water to prepare cement mortar, and add 8.9% cast iron gravel to improve its wear resistance. This method is simple and feasible, but the density of cast iron is high, which is easy to cause delamination and Segregation, poor surface strength, and easy to form microcracks on the surface

Abstract

The invention discloses wear-resistant cement mortar, a wear-resistant floor and a preparation method thereof, wherein the wear-resistant cement mortar is composed by mixing the following components according to a normal method, by weight, 22-40 parts of ordinary portland cement, 1.9-7.5 parts of slag powder, 1-5 parts of special cement, 1-5 parts of metakaolin, 1-5 parts of gypsum, 40-60 parts of quartz sand, 1-3 parts of calcium silicate seed crystal; 1-7 parts of nano alumina powder and 0.1-0.3 part of a water reducing agent, wherein the special cement is sulphoaluminate cement or aluminate cement. The wear-resistant cement mortar has the advantages of excellent hardness and strength. The wear-resistant floor prepared by the wear-resistant cement mortar has no micro-cracks on the surface after being grinded; good smoothness and various fresh brilliant colors can be obtained; color ordonnance can be realized on the surface with extremely high compactness; and aesthetic patterns with paint effects can be obtained.

Description

technical field [0001] The invention relates to a cement mortar, a floor and a preparation method thereof, in particular to a wear-resistant cement mortar, a wear-resistant floor and a preparation method thereof. Background technique [0002] Self-leveling floors made of cement mortar and polymers are widely used in waterproofing, repairing, underground garages and anti-corrosion fields. With the development of technology and the needs of engineering, the demand for various functional floors is also increasing. Wear-resistant cement mortar has become the main choice for heavy-duty parking lots and metal processing industrial plants due to its superior wear resistance, high compressive and flexural strength, good impact resistance and surface hardness. However, the technical content of the wear-resistant floor is relatively high, and there are also disadvantages such as complex construction, unstable performance, and micro-cracks on the surface. [0003] At present, there ar...
