Embodiment 1
[0026] A concrete curing agent, which is made of the following raw materials in weight ratio: 8 kg of paraffin wax, 5 kg of nano-scale calcium carbonate, 1 kg of film-forming aid, 1 kg of sorbitan monofatty acid ester, and 1 kg of triethanolamine , 0.2 kg of dispersant and 85 kg of water.
[0027] Wherein the particle size of nano-scale calcium carbonate is 0.1nm-100nm; the film-forming aid is ethylene glycol or ethylene glycol butyl ether; the dispersant is polyhydroxy acid salt, sulfamate or naphthalene sulfonate.
[0028] The above-mentioned nano-scale calcium carbonate filler can block the capillary channels of concrete and hinder the volatilization of water. Film-forming aids have the characteristics of high adhesion, waterproof, wear-resistant, high temperature resistance and anti-sticking.
[0029] The preparation method of above-mentioned concrete curing agent, its concrete steps are as follows:
[0030] (1) Add paraffin, sorbitan monofatty acid ester and triethanola...
