Embodiment 1

[0025] A clear-faced concrete protective coating is prepared by the following method:

[0026] 1) Primer coating: the mass ratio of cement, silica fume, sodium dodecylsulfonate, styrene-acrylate dispersible latex powder is 60:30:1:9, water-binder ratio = 1.0; surface coating Layer: the mass ratio of silane emulsion, ultrafine aluminum silicate and lithium silicate is 90:5:5;

[0027] 2) Pour the weighed cement, silica fume, sodium lauryl sulfonate and dispersible latex powder into the concrete mixer and dry mix for 2 to 3 minutes to obtain the dry powder of the bottom coating of the clear water facing concrete protective coating;

[0028] 3) Pour the weighed silane emulsion, ultra-fine aluminum silicate and lithium silicate into the mixer and stir for 5-10 minutes to obtain the mixed emulsion of clear water facing concrete protective coating surface layer coating;

[0029] 4) The concrete base surface needs to be cleaned and moistened before the primer coating is applied to r...

Embodiment 2

[0045] A clear-faced concrete protective coating is prepared by the following method:

[0046] 1) Primer coating: the mass ratio of cement, silica fume, sodium dodecylsulfonate, styrene-acrylate dispersible latex powder is 65:25:1:9, water-binder ratio = 0.95; surface coating Layer: the mass ratio of silane emulsion, ultrafine aluminum silicate and lithium silicate is 90:5:5;

[0047] 2) Pour the weighed cement, silica fume, sodium lauryl sulfonate and dispersible latex powder into the concrete mixer and dry mix for 2 to 3 minutes to obtain the dry powder of the bottom coating of the clear water facing concrete protective coating;

[0048] 3) Pour the weighed silane emulsion, ultra-fine aluminum silicate and lithium silicate into the mixer and stir for 5-10 minutes to obtain the mixed emulsion of clear water facing concrete protective coating surface layer coating;

[0049] 4) The concrete base surface needs to be cleaned and moistened before the primer coating is applied to re...

Abstract

The invention belongs to the field of building materials, and in particular relates to a protective coating for clear water facing concrete. Latex powder and water are configured in a certain proportion, and the surface coating is mainly composed of silane emulsion, ultrafine aluminum silicate and lithium silicate in a certain proportion. The clear water finish concrete protective coating of the present invention has excellent hardness, water resistance, weather resistance and high cohesion, can effectively improve the durability of the concrete structure, and make the appearance of the concrete structure consistent with the original color of the concrete, and more glossy It can effectively solve the problems of urban concrete structure surface fouling and durability reduction, and has important practical application value. The preparation method and construction process of the invention are simple, easy to operate, low in cost, and have practical popularization value.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a clear-faced concrete protective coating and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of urban construction in our country, the construction of express roads such as urban viaducts and overpasses has been widely used in cities. However, due to the impact of smog, exhaust gas, acid rain, pollution, accidents, etc., the surface of concrete structures serving in urban environments is seriously polluted, which not only affects the appearance of concrete structures, but also reduces the durability of concrete structures. Therefore, in order to improve the appearance of the city and increase the service life of the concrete structure, it is necessary to clean up and repair the polluted concrete structure. [0003] At present, in order to improve the durability of concrete structures, concrete surface treatmen...
