Abstract

The invention discloses a cement sealing curing agent and a preparation method thereof. The curing agent is prepared by mixing component A and component B at a ratio of 6:1, and the raw material formula of component A includes sodium polysilicate, polysilicic acid Lithium, hydroxyethyl cellulose, zeolite, metakaolin, sodium dihydrogen phosphate, wetting agent, penetrant, defoamer, surface modifier, stabilizer, deionized water, the raw material formula of component B includes aliphatic Urethane Acrylate, Trimethylolpropane Triacrylate, Nano Graphene Oxide, Nano Iron, Aluminum Hydroxide, Aluminum Sulfate, Sodium Hydroxide, Deionized Water. The permeability of the present invention is stronger, which greatly improves the strength and wear resistance of the surface layer of the concrete structure, and prolongs the service life of the ground. Component A of the curing agent can be used alone, but under the action of component B, it will be greatly To shorten the curing time and increase its strength to a certain extent, component B plays a synergistic effect on component A.

Description

technical field [0001] The invention relates to the technical field of sealing and curing agents, in particular to a cement sealing and curing agent and a preparation method thereof. Background technique [0002] Sealing and curing agent, also known as liquid hardener or concrete (cement) sealant, can effectively penetrate into the concrete and react chemically with it, lock the pores inside, and have a permanent sealing effect on the concrete surface. The strength and hardness of the ground can control the ground from sand and dust, prevent chemical erosion and weathering. However, the existing sealing and curing agents are generally made of single-component materials, and their penetration effect, curing time, hardness and strength still need to be improved. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned defects in the prior art, and provide a cement seal curing agent and a preparation method thereof. [0004] ...
