Abstract

The invention discloses an environment-friendly low-temperature-resistant concrete interface treatment agent and a preparation method thereof, belonging to the technical field of adhesives. The components of the concrete interface treatment agent include in parts by mass: 750-850 parts of water, 50-90 parts of polyvinyl alcohol, 1-3 parts of catalyst, 1-2 parts of crosslinking agent, 2-3 parts of pH regulator, 100-150 parts of EVA emulsion, 3-5 parts of citric acid, 10 parts of silica sol, 2-3 parts of defoamer, 1-2 parts of preservative. The concrete interface treatment agent has the characteristics of high adhesion, high shear strength, low temperature resistance, environmental protection and pollution-free, short production hours and low energy consumption.

Description

technical field [0001] The invention belongs to the field of adhesive technology, and in particular relates to an environment-friendly low-temperature-resistant concrete interface treatment agent and a preparation method thereof. Background technique [0002] Concrete interface treatment agent is widely used in construction engineering and is an indispensable material in construction engineering. Concrete interface treatment agent is mainly used for roughening the surface of building concrete to improve the surface roughness of concrete and enhance the adhesion between coating and wall. Focus on it, so as to prevent the internal and external wall coatings from falling off and hollowing out. The current concrete interface treatment agent has insufficient bonding strength, and at the same time, the strength of the rough layer formed with cement is not enough, and the low temperature resistance is poor. The construction of the concrete interface treatment agent is subject to ma...
