Description
Technical Field
The invention belongs to the technical field of building coatings. More particularly, relates to an exterior wall coating for buildings and a preparation method thereof.
Background
In the process of building construction, the overall quality of a building needs to be considered, and the quality of the building construction is improved by holding the material selection in the building construction process. The building coating is one of building materials frequently used in the building construction process, and because the outer wall of a house is greatly influenced by external factors, the coating is selected according to the principle of applicability and durability in the decoration process of the outer wall, so that the influence of the external factors on the decoration of the outer wall can be reduced, and the service life of the outer wall is further prolonged. In some areas with strong illumination, the selection of the exterior wall coating is very prudent, and the corresponding building coating is selected by knowing the local natural environment, which has better guarantee on the quality of the building construction.
In the use process of the outer wall, once the service life is prolonged, the problems of color fading, chalking, peeling and the like occur on the surface of the outer wall, and the service life of the outer wall is greatly shortened. The main reason for such problems is that the quality of the surface of the exterior wall is gradually deteriorated due to the exposure of the exterior wall for a long time and the long-term damage of ultraviolet rays, rain water, and the like. The general place that appears pulverization, spalling scheduling problem is the wall base part of outer wall, and the surface of outer wall appears the large tracts of land to spall, makes the outer wall receive serious damage, has reduced the use experience of house more.
Particularly, as an exterior wall coating, the exterior wall coating is often subjected to rainwater erosion, how to keep the shape of the exterior wall coating stable, endure repeated rainwater erosion, protect a wall body, and avoid the problem of an inner wall caused by water seepage of the wall body is one of the technical problems faced by exterior wall coating developers.
Disclosure of Invention
The invention aims to solve the technical problem of overcoming the defects and shortcomings of the existing exterior wall coating product that the washing resistance is insufficient in the actual use process, so that the water seepage of a wall body is caused, and the interior wall is influenced, and provides an exterior wall coating for a building and a preparation method thereof.
The invention aims to provide an exterior wall coating for buildings.
The invention also aims to provide a preparation method of the exterior wall coating for the building.
The above purpose of the invention is realized by the following technical scheme:
an exterior wall coating for buildings comprises a pure acrylic emulsion and nano titanium dioxide;
the pure acrylic emulsion comprises emulsion particles, the sphericity of the emulsion particles is 0.8-0.9, and the particle size distribution range of the emulsion particles is 300-400 mu m;
the sphericity of the nano titanium dioxide is 0.8-0.9, and the particle size distribution range of the nano titanium dioxide is 60-80 nm;
the addition amount of the nano titanium dioxide is 0.8-1.2% of the mass of the pure acrylic emulsion.
The technical scheme takes the acrylic emulsion and the nano titanium dioxide as the raw materials of the building exterior wall coating, two raw materials with relatively high sphericity are adopted, in the drying process of the coating, the water between emulsion particles and nano titanium dioxide particles is gradually volatilized, continuous coating film layers can be gradually formed between the particles, the smooth paint film surface structure similar to the wave shape can be regulated and controlled by controlling the sphericity of the emulsion particles, the particle size distribution of the emulsion particles, the sphericity and the particle size distribution of the nano titanium dioxide and the using amount of the nano titanium dioxide, particularly, the particle size of the emulsion particles is relatively large, the coagulation effect is realized in the drying process, but when large particles and large particles are aggregated, sharp corners are easily formed to influence the smoothness of the paint film surface, and the emulsion particles with relatively good sphericity only can ensure that the positions of single emulsion particles are relatively smooth, but the smoothness of the paint film area formed by the particles and the particles cannot be effectively guaranteed, when nano titanium dioxide with the particle size distribution obviously different from that of emulsion particles is added, and the sphericity and the addition amount of the nano titanium dioxide are controlled, the nano titanium dioxide can be filled among the emulsion particles with large particles, so that the paint film layer among the emulsion particles is relatively smooth, and thus, when the surface of the paint film is washed by rainwater, the smooth wavy paint film surface can quickly decompose the stress such as the impact force of rainwater and the like to the whole surface of the paint film, the local cracking of the paint film caused by local stress is avoided, and the washing and brushing resistance is effectively improved.
Further, the solid content of the pure acrylic emulsion is 45-50%.
Furthermore, the exterior wall coating comprises water-absorbent resin which accounts for 0.01-0.05% of the mass of the pure acrylic emulsion.
Further, the water-absorbing resin is selected from any one of polyethylene oxide, polyvinyl alcohol, sodium polyacrylate and polyacrylamide.
According to the technical scheme, a very small amount of water-absorbent resin is further introduced into the system, the water loss rate of the paint film in the drying process can be effectively regulated and controlled, the forming process of the paint film is regulated and controlled, if the addition amount of the water-absorbent resin is too large, the paint film absorbs water and swells when a product is impacted by rainwater, so that the surface cohesion of the paint film is reduced in the scouring process, the local damage is caused, and the scouring resistance is reduced.
Further, the exterior wall coating comprises the following raw materials:
60-80 parts of pure acrylic emulsion, 0.2-0.4 part of sodium hexametaphosphate, 15-20 parts of titanium dioxide, 0.1-0.5 part of defoaming agent, 0.2-0.4 part of dispersing agent, 1-2 parts of ethylene glycol, 0.3-0.5 part of glycerol, 0.2-0.4 part of preservative and 30-40 parts of water;
and nano titanium dioxide with the mass of 0.8-1.2% of the pure acrylic emulsion.
Further, the defoaming agent is any one selected from the group consisting of silicone emulsion, polyoxyethylene polyoxypropylene pentaerythritol ether, polyoxyethylene polyoxypropylene amine ether, polyoxypropylene glycerol ether, polyoxypropylene polyoxyethylene glycerol ether, and polydimethylsiloxane.
Further, the dispersing agent is selected from any one of calcium stearate, magnesium stearate or zinc stearate.
Further, the preservative is selected from any one of nord BT20, nord BK and nord C15.
A preparation method of an exterior wall coating for buildings comprises the following concrete preparation steps:
adding nano titanium dioxide and pure acrylic emulsion serving as a mixed material into a ball milling tank, and mixing the nano titanium dioxide and the pure acrylic emulsion in a ratio of 1: 3-1: 5, adding ball milling beads with the diameter of 5cm and ball milling beads with the diameter of 8cm into a ball milling tank, wherein the mass ratio of the ball milling beads to the mixed material is 20: 1-25: 1, ball milling and mixing for 2-4h at the temperature of 45-55 ℃, the revolution speed of 200-.
According to the technical scheme, the ball milling process is adopted, so that the emulsion particles with specific sphericity and particle size distribution and the nano titanium dioxide are stable in shape, can be uniformly dispersed, and is beneficial to forming a smooth wavy paint film.
