Problems solved by technology

The cost of latex type is high, and the film after film formation is difficult to remove; the water retention rate of silicate type is low, and it is not suitable for drought, hot, anhydrous, and windy climate conditions; although emulsion type can overcome the above shortcomings, it has low water retention rate, Disadvantages such as short curing time, less spraying area of ​​curing agent per unit mass and inconvenient use

Embodiment 1

[0020] Concrete curing agent, the components are proportioned as follows by weight: paraffin 8Kg, sorbitan monofatty acid ester 1Kg, triethanolamine 1Kg, stearic acid 0.5Kg, glycerol monostearate 0.5Kg, ethylene glycol monostearate Fat 0.5Kg, water 50Kg.

[0021] The preparation method of the concrete curing agent: take the paraffin wax, sorbitan monofatty acid ester, triethanolamine, stearic acid, glycerol monostearate and pearl flakes of the above weight in a reaction kettle and heat them to melt completely, then add dropwise Warm water at 50-60°C, add dropwise and stir until it becomes a milky white liquid to get this concrete curing agent.

[0022] Dilute the curing agent made according to the above ratio by 8m 2 / kg sprayed on the surface of the test piece, the measured data are as follows:

[0023]

Embodiment 2

[0025] In the present embodiment, each component is proportioned by weight: paraffin wax 10g, sorbitan monofatty acid ester 2Kg, triethanolamine 2Kg, stearic acid 1Kg, glycerol monostearate 1Kg, stearic acid ethylene glycol double fat 1Kg , 60Kg of water.

[0026] The preparation method is the same as in Example 1.

Embodiment 3

[0028] In the present embodiment, each component is proportioned by weight: 12Kg of paraffin wax, 3Kg of sorbitan monofatty acid ester, 3Kg of triethanolamine, 1.5Kg of stearic acid, 1.5Kg of glycerol monostearate, ethylene glycol monostearate Fat 1.5Kg, water 70Kg.

[0029] The preparation method is the same as in Example 1.

Abstract

The invention discloses a concrete curing agent and a preparation method thereof. The agent is prepared from paraffin, sorbitan mono fatty glyceride, trolamine, stearic acid, glycerin monostearate and EGDS. The agent is mainly applied to the concrete curing under climatic conditions of drought, insufficient water, torridity and wind, and the water retention rate is obvious and reaches more than 99 percent; and the curing time is long, up to 3 to 12 months. The curing agent can be directly used without being diluted, and the spray-coating area reaches 8 to 10m<2> / kg, and the excessive spray-coating does not damage concrete performance.

Description

technical field [0001] The invention relates to a building material additive, in particular to a concrete curing agent and a preparation method thereof. Background technique [0002] After the concrete is poured, sufficient temperature and humidity must be ensured during the initial setting process to fully hydrate the concrete. The traditional maintenance methods include laying grass bags, plastic films, and sprinkling water. These methods are labor-intensive, time-consuming, and waste of resources. Comprehensive The cost is high, and the evaporation of water cannot be effectively prevented, and the maintenance effect is not good. Therefore generally use concrete curing agent to carry out curing to concrete at present. Concrete curing agents can be roughly divided into latex type, silicate type and emulsion type. The cost of latex type is high, and the film after film formation is difficult to remove; the water retention rate of silicate type is low, and it is not suitabl...
