preparation example Construction

[0037]The present application also relates to a preparation method of the concrete curing agent, the method comprising the following steps:

[0038] (1) Dissolve the stabilizer and the quick-hardening component in water respectively to form a stabilizer solution and a quick-hardening component solution for subsequent use;

[0039] (2) Add paraffin wax emulsion, defoamer, plasticizer, and film-forming aid into the reaction vessel at one time and stir evenly. Usually, the stirring time is about 1-2 minutes, and the stirring speed is controlled at 100-300r / min;

[0040] (3) Add the EVA emulsion and the silicone-modified acrylate emulsion into the reaction vessel in turn and stir, the stirring speed is controlled at 400-500r / min, after adding the two emulsions, continue to stir for 0.5-1min;

[0041] (4) The standby stabilizer solution and the quick-hardening component solution are added to the reaction vessel successively, and the remaining water (i.e., deduct the water in the st...

Embodiment 1

[0051] The curing agent used for early curing of cement concrete pavement in this embodiment is composed of the following components: 55 parts by mass of paraffin emulsion, 15 parts by mass of EVA emulsion, 5 parts by mass of silicone modified acrylate emulsion, 0.8 parts by mass of stabilizer, 0.06 parts by mass of foaming agent, 0.7 parts by mass of plasticizer, 0.8 parts by mass of film-forming aid, 0.5 parts by mass of rapid hardening component, and 22.14 parts by mass of water.

Abstract

The invention relates to an early-strength wear-resistant concrete curing agent, as well as a preparation method and application thereof, and belongs to the field of concrete construction. The curing agent comprises the following components in percentage by weight (based on the total weight of the curing agent): 45-65% of paraffin emulsion, 10-20 % of EVA emulsion, 3-8% of organosilicon modified acrylic ester emulsion, 0.5-1% of a stabilizing agent, 0.03-0.08% of a foam killer, 0.5-1% of a plasticizer, 0.6-1% of a coalescing agent, 0.3-0.8% of a rapid hardening component and the balance of water.

Description

technical field [0001] The application relates to an early-strength wear-resistant concrete curing agent and its preparation method and use, belonging to the field of concrete curing. Background technique [0002] The traditional concrete maintenance method is to cover wet sacks, wet straw bags or wet sand and then sprinkle water, which consumes manpower, material resources and time, and cannot meet the construction requirements of high-rise, large buildings and buildings in water-deficient and arid areas. With the development of concrete technology, chemical regimen came into being. The chemical curing method is mainly to prevent the water loss inside the concrete by spraying and applying film-forming materials on the surface of the building. Compared with the traditional curing method, it has the advantages of labor saving, time saving, and water saving. It is suitable for highways, Maintenance of airport pavements, high-rise buildings, bridges and other projects. It als...
