Early strength two-component polymer emulsion modified cement tile binder and using method thereof

Abstract

The invention relates to an early strength two-component polymer emulsion modified cement tile binder and a using method thereof. The tile binder comprises a liquid material and powder in a weight ratio of 1 to (3-4.5), wherein the liquid material is prepared from the following raw materials: 25-35 parts of modified butadiene-styrene copolymer emulsion, 1-4 parts of nonionic surfactant and 60.75-73.96 parts of water; and the powder is prepared from the following raw materials: 15-30 parts of 42.5-grade ordinary Portland cement, 6-20 parts of high-alumina cement, 3-5 parts of anhydrite, 35-56 parts of 40-200-mesh quartz sand and 0-10 parts of 320-mesh ground calcium carbonate. The tile binder has the beneficial effects that the early strength technology used for the two-component polymer modified cement tile binder is invented; the construction time, opening time and property of high hardening rate of the material are well balanced; the construction period is greatly reduced; the labor cost is saved; and meanwhile, performance characteristics, such as alkali efflorescence resistance and aging resistance, are improved.

Description

(1) Technical field [0001] The invention belongs to the technical field of building tile adhesives, and in particular relates to an early-strength type two-component polymer emulsion modified cement tile adhesive and its application method. (2) Background technology [0002] Tile adhesives, also known as tile adhesives or tile adhesives, are mainly used to paste decorative materials such as ceramic tiles, facing tiles, and floor tiles. Tile adhesive is a substance that plays a bonding role between tiles and walls, floors, etc. It is required to have certain bonding strength, shear strength, anti-pan-alkali, anti-aging and other properties. The tile adhesives currently on the market need 24 hours or more to develop strength after use, and then the next process can be carried out, which increases labor costs and increases construction time. Moreover, the anti-pan-alkali and anti-aging properties of this tile adhesive are poor, which affects the appearance of the building and ...
