Problems solved by technology

[0003] (2) When watering and maintaining, the water consumption is large, and it is difficult to maintain in arid and water-deficient areas
[0004] (3) When wrapping with plastic cloth, the plastic cloth is easy to be damaged, aged, cracked and the water at the overlap is easy to evaporate quickly, which will affect the quality of the project
[0005] (4) Mulches (sawdust, straw...) fly with the wind, causing air and water pollution
It is composed of acrylic polymer, wax emulsion, film-forming agent, wetting agent, penetrating agent, leveling agent, etc. It has certain film-forming and penetrating properties, and can prevent rapid evaporation of water, but the cost of raw materials is relatively high

Abstract

The invention relates to a cement concrete highly-efficient curing agent and a preparation method thereof. The curing agent is made from the following self-prepared materials and raw materials purchased from the market according to part by weight: 38.33 to 357.70 parts of inorganic bonding agent, 0.69 to 6.44 parts of rust resisting and inhibiting agent, 1.56 to 14.56 parts of composite enhancer, 0.02 to 0.21 part of catalyst and 9.00 to 84.00 parts of thinner.

Description

technical field [0001] The invention relates to additives of cement concrete, especially to curing and strengthening agents. technical background [0002] In order to prevent the formula water in the concrete pouring body from evaporating quickly, to have sufficient water supply when the cement hydrates and develop strength, and to ensure the quality of the project, curing agents must be used. The traditional method is to cover sawdust, straw or sacks, straw bags, and plastic sheets on the plane of the concrete pouring body that has been removed from the film, and continuously water and maintain it for more than seven days. The disadvantages of this method are many: (1) watering and curing on the covering can only be carried out on the plane of the concrete pouring body. It is difficult to maintain the straight, inclined and curved surfaces of concrete construction projects. [0003] (2) When watering and maintaining, the water consumption is large, and it is difficult to ...
