Abstract

The invention discloses a protective cement concrete curing agent. The protective cement concrete curing agent is an emulsifier-free protective cement concrete curing agent prepared through aqueous polymerization of butyl acrylate, styrene and hydroxypropyl methacrylate and has an effective solid content of 5 to 25%. In virtue of the high-barrier property of graphene, the curing agent is further improved in the compactness and barrier effect on moisture and carbon dioxide after film formation, and the water-retention rate, carbonization resistance and other performance of the curing agent are improved; and the protective cement concrete curing agent can function both as a cement concrete curing agent and a protective paint, so protection and curing of cement concrete are integrated.

Description

technical field

[0001] The invention relates to a protective cement concrete curing agent, which belongs to the field of chemical building materials.

[0002] technical background

[0003] Cement concrete is the most widely used composite material in the world and is widely used in various projects. Curing is an important part of concrete construction. After concrete is poured, it must be cured during the setting and hardening process so that it has enough water to ensure the hydration reaction. Proper curing can greatly improve the durability, strength, and durability of concrete. Abrasiveness, volume stability and other properties.

[0004] Traditional maintenance methods include grass bag maintenance, plastic film maintenance and watering maintenance, etc. These methods are time-consuming, labor-intensive and seriously waste water resources. The method of curing concrete with a film-forming curing agent has a long history. The curing agent forms a dense isolation layer o...
