Abstract

The invention relates to a three-component epoxy ester cement mortar composite self-leveling material and a preparation method thereof. The material includes a powder component, a first liquid component and a second liquid component; the powder component consists of the following parts by weight Raw material composition: 250 to 350 parts of P.0 42.5R cement; 650 to 750 parts of 70 to 140 mesh quartz sand; 0.7 to 1.2 parts of modified polycarboxylate water reducer; 1 to 1.5 parts of defoamer part; the first liquid component consists of the following parts by weight of raw materials: 50 parts to 65 parts of epoxy ester emulsion; the second liquid component consists of the following parts by weight of raw materials: 50 parts to 65 parts of nonionic epoxy curing agent; 100 to 130 parts of water. The self-leveling material of the invention solves the problems of cracking, deformation and shedding of the existing cement-based self-leveling material.

Description

technical field [0001] The invention relates to the technical field of self-leveling, in particular to an epoxy ester cement mortar composite self-leveling material and a preparation method thereof. Background technique [0002] Self-leveling material is a solvent-free, self-leveling, thick-build epoxy floor coating with dense particles. It is generally a liquid formed by mixing various materials with water. After the liquid is poured into the ground, it can be used according to the unevenness of the ground. Flow, automatic leveling of the ground, a good solution to the problems in the floor installation. [0003] Cement-based self-leveling materials are relatively common self-leveling materials. They are generally made by mixing cement-based cementitious materials, fine aggregates, fillers, and powdered additives. Before use, add an appropriate amount of water and stir evenly. Most of the cement-based self-leveling materials have the advantages of high early strength, good...
