Abstract

The invention discloses a concrete curing agent, which is prepared from the following raw materials in parts by weight: 10 to 15 parts of paraffin emulsion, 10 to 20 parts of styrene-acrylic emulsion, 5 to 10 parts of repairing microcapsules, 5 to 8 parts of sodium silicate, 5 to 8 parts of magnesium sulfate, 5 to 8 parts of aluminum sulfate, 4 to 10 parts of animal and plant fibers, 10 to 20 parts of methyl methacrylate, 1 to 1.5 parts of defoaming agents, 1 to 3 parts of flatting agents, 0.2 to 0.4 part of plasticizers and 20 to 30 parts of deionized water. The invention discloses a preparation process of the concrete curing agent, the concrete curing agent is prepared by compounding inorganic components and organic components and is non-toxic, odorless and non-combustible, and the repairing microcapsules are added, so that the mechanical property of concrete is improved while concrete cracks are repaired and bonded, and therefore, the prepared concrete curing agent not only has high water retention and high repairing performance, and can enhance the mechanical property of the concrete structure.

Description

technical field [0001] The invention belongs to the technical field of concrete additives, and in particular relates to a concrete curing agent and a preparation method thereof. Background technique [0002] In the construction or production process of prefabricated materials in highways, airports and cement factories, because the cement solidification and hardening process requires a large amount of water to carry out its own hydration reaction, the water retention and maintenance of the cement gelled structure directly affects the project or project. The quality of prefabricated products. There is usually a curing period of 7-28 days after concrete is poured. The shrinkage of concrete and the resulting cracking are a persistent problem in the quality of concrete engineering, and they have also been concerned by academic and engineering circles. In order to prevent moisture from evaporating and losing during the curing process, conditions must be created during constructio...
