Abstract

The invention discloses an environment-friendly water-based interface agent and a preparation method thereof. The interface agent contains 25-30 parts of alicyclic epoxy resin, 70-75 parts of bisphenol A type epoxy resin, and a Mannich base type curing agent. , 1-2 parts of amine accelerator, 1.5-2 parts of Span 601.5-2 parts, 3.2-4 parts of sodium polyethylene glycol sulfonate, 8-10 parts of nano-polyanion cellulose, 30-45 parts of quartz sand, 10-2 parts of silica fume 20 parts, 5-10 parts of cellulose ether, the water-based interface agent is less affected by the roughness of the interface, can greatly improve the bonding force of mortar, new and old concrete, strengthen the interface strength, solve problems such as hollowing and cracking, and prevent seepage Durable, strong frost resistance, healthy and environmentally friendly.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to an environment-friendly water-based interface agent and a preparation method thereof. Background technique [0002] Concrete is a common building material with good compressive properties and low cost. However, during the use of concrete, due to its weak elongation, its structure is prone to cracking and water seepage, which will not only affect the bearing capacity and durability of concrete. reduction, and may cause safety accidents. Therefore, regular structural maintenance, reinforcement and reconstruction of concrete are required. In this process, the interface bonding between old and new concrete is often involved. The bond strength is low, especially when the interface is relatively smooth, resulting in hollowing, cracking or even peeling of the repaired concrete after a period of work, which damages the use function and safety of the overall structure again, ...
