Abstract
The invention discloses a surface-film-forming coating for concrete. The coating is prepared by the following components in percentage by weight: 1-10% of an acrylic acid-acrylamide copolymer, 5-10% of a styrene-acrylic acid copolymer, 0.1-0.5% of a wax emulsion, 0.1-0.7% of fatty alcohol-polyoxyethylene ether, 1-8% of inorganic micropowder, 0.1-0.5% of an organic silicon defoamer and the balance of water. The surface-film-forming coating for concrete disclosed by the invention has the functions of preventing water, moisture and corrosion, resisting seepage, carbonization and cracking and the like, is simple, convenient, labor-saving and time-saving to operate, and has no special requirements on the construction environments and conditions. By using the film-forming coating, the comprehensive cost of a concrete building can be lowered, the economical benefit is improved, and the coating has a wide engineering application prospect.
Description
Technical field
The present invention relates to construction engineering technical field, particularly a kind of concrete surface film-forming type coating.
Background technology
Concrete structure, particularly concrete floor are widely used in the fields such as factory building, highway, supermarket, garage.After concrete surface drying and moulding, surface there will be dusting, plays dirt, honeycomb and scale phenomenon, and surface hardness can reduce, simultaneously also can at generation space, surface even crackle.
For above concrete structure Problems existing, modern technologies generally adopt concrete permeability curing sealing agent to carry out surface treatment to concrete structure.Concrete osmosis type curing sealing agent is a kind of multicomponent coating, viscosity is little, be coated in concrete surface due to wicking action can very fast inside concrete, form insoluble non-crystalline state hydrated calcium silicate, thus realize the shutoff of concrete structure, improve hardness, the wear resistance on surface.But these concrete osmosis type curing sealing agents do not form layer protecting film at surface of concrete buildings, and it is coated, and decorative effect is poor, unsightly, and now commercially concrete surface film-forming type coating is shorter.Therefore, use concrete surface film-forming type coating can improve the structure density of concrete structure, good decorating effect, specious, long service life.
Summary of the invention
In order to solve the problem, the invention provides a kind of concrete surface film-forming type coating.
To achieve the object of the present invention, the technical scheme of employing is as follows:
A kind of concrete surface film-forming type coating, the weight percent of each component is:
Acrylic acid acrylamide copolymer 1% ~ 10%
Styrene acrylic copolymer 5% ~ 10%
Wax emulsion 0.1% ~ 0.5%
Fatty alcohol-polyoxyethylene ether 0.1% ~ 0.7%
Inorganic micro powder 1% ~ 8%
Silicone antifoam agent 0.1% ~ 0.5%
The water of surplus, gross weight is in 100%.
Described acrylic acid acrylamide copolymer to be vinylformic acid and acrylamide be monomer synthesize, solid content is 30%;
Described styrene acrylic copolymer to be vinylbenzene and vinylformic acid be monomer synthesize, solid content is 50%.
Concrete surface film-forming type coating of the present invention, can alleviate the alkali pasc reaction of concrete untoward reaction, can solve the dusting of concrete surface, play dirt, honeycomb and scale phenomenon, lower or avoid the seminess of concrete surface to a great extent.This surface filming type coating has the functions such as waterproof, protection against the tide, LP blades, impervious, anti-carbonization, cracking resistance, and simple, convenient, saving of labor, saves time.The use of this film-forming type coating can reduce the comprehensive cost cost of concrete structure, increases economic efficiency, and has wide future in engineering applications.
