Abstract
The invention relates to a concrete sealing and curing agent and its preparation method and construction method, belonging to the technical field of concrete restoration. The sealing and curing agent includes A component and B component, and A component includes water-based terpene resin sol and propylene glycol dishrink Glyceryl ether; component B includes active cementitious material, expanded perlite 10~15 parts; this application applies component B on the concrete surface, component B has good compatibility with the old concrete floor, continue to coat A Components, A component is to add water-based terpene resin sol and propylene glycoldiglycidyl ether on the basis of the existing seal curing agent, and use the above components A and B to repair the old concrete, which will help to promote this The sealing and curing agent is better integrated with the old concrete, filling the originally loose honeycomb structure to form a compact entity, effectively isolating water vapor, oil, etc., and improving the compactness of the old concrete, so the sealing and curing agent of this application has both It has sealing and repairing functions.
Description
technical field [0001] The invention relates to the technical field of concrete restoration, in particular to a concrete sealing and curing agent, a preparation method and a construction method thereof. Background technique [0002] Concrete sealing and curing agent is a colorless, odorless, non-toxic liquid sealant, which can fully chemically react with the chemical components in concrete and stonework through effective penetration to form a high-strength, high-hardness curing Floor, chemical reaction products can block the pores of concrete from the inside, so that the concrete is transformed into a solid and sealed whole, which effectively improves the strength and density of the floor, prevents dust, and at the same time carefully polishes the ground, which can make the floor The ground produces a higher gloss, which increases the aesthetic effect of use. [0003] At present, the popular concrete sealing and curing agents on the market can be roughly divided into two ca...
