Concrete curing agent

Abstract

The invention discloses a concrete curing agent, which comprises the following components in parts by mass: 20-25 parts of styrene-acrylic emulsion, 7-10 parts of acrylamide solution, 7-9 parts of sodium silicate solution, 6-9 parts of organic silicon solution 8 parts, 1-3 parts of methyl methacrylate, 1-3 parts of polyethylene glycol monomethyl ether acrylate, 3-5 parts of polyethylene glycol, 1-3 parts of polyvinyl alcohol, 4-6 parts of styrene , 6-8 parts of methyl acrylate, 5-7 parts of butyl methacrylate, 3-5 parts of butyl acrylate, 4-6 parts of ethyl methacrylate, 1-3 parts of ammonium thiosulfate, EPDM 1-3 parts of rubber, 0.7 parts of butyl citrate, 1 part of soda ash, 0.5 parts of gypsum powder, 0.1 part of periodate lignin, 0.1 part of surfactant, 0.2 part of defoamer, 0.3 part of leveling agent and benzene 1 part methanol. The curing agent disclosed by the invention can effectively prevent water loss inside the concrete, and is environmentally friendly and pollution-free.

Description

technical field [0001] The invention relates to a concrete curing agent. Background technique [0002] After the cement concrete is poured, it must have the necessary temperature and humidity during the initial setting process to ensure enough water to make the hydration reaction complete. The traditional maintenance methods include laying grass bags, plastic films and watering. These methods It is troublesome and laborious, and cannot effectively block the evaporation of water, the protection rate is low, and the maintenance effect is not good. At present, people often use concrete curing agent to maintain concrete, but the current concrete curing agent cannot effectively prevent the efflorescence phenomenon of capillary pores. Contents of the invention [0003] It is an object of the present invention to solve at least the above-mentioned problems and to provide at least the advantages which will be described later. [0004] Another object of the present invention is t...
