Abstract

The invention relates to a dry-mixed wear-resistant floor mortar and a preparation method thereof. The dry-mixed wear-resistant floor mortar is prepared from the following raw materials in parts by weight: 80-100 parts of Portland cement, 10-20 parts of corundum, 10-20 parts of aluminum powder, 15-20 parts of nano bentonite, 5-8 parts of nano ceramic powder, 7-10 parts of modified nano calcium carbonate, 20-40 parts of rubber powder, 3-6 parts of methyl cellulose ether, 3-5 parts of polypropylene fiber, 10-12 parts of fly ash, 8-10 parts of gypsum, 1-3 parts of silicon defoaming agent and 1-3 parts of naphthalene sulfonate water reducing agent. The dry-mixed wear-resistant floor mortar has excellent wear resistance, impact resistance and bonding properties, and can reduce the ground dust and increase the oil resistance of the ground, thereby forming the high-density easy-to-clean anti-permeation ground, and avoiding the phenomena of whitening, sand fallout and the like of the mortar in the later period.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a dry-mix wear-resistant floor mortar and a preparation method thereof. Background technique [0002] As an important building material, mortar has a wide range of uses. Floor mortar is a mortar material composed of Portland cement or ordinary Portland cement, wear-resistant aggregate, and an appropriate amount of additives. At present, floor mortar is widely used in shopping centers, large supermarkets, parking lots, production workshops, warehouses and other places. Therefore, floor mortar is required to have excellent wear resistance and impact resistance, which can reduce dust on the ground. However, the surface wear resistance of the floor mortar in the prior art is not high, the strength will decrease in the later stage, and problems such as whitening and sand removal appear on the surface of the mortar. Contents of the invention [0003] The purpose of the p...
