The invention relates to a surface penetrating type sealant, which takes industrial alcohol as a dielectric solution, and the components of the sealant mainly comprise organic silicon, vinyl acetate and butyl acrylate. The protective agent can be used for impregnating the concrete surface and the stone surface layer by 0.3mm and covering the surface to form a sealing layer to prevent permeation, but the appearance characteristic and the air permeability of the concrete are not changed. The concrete and stone can be protected from the penetration and erosion of external water, acid, alkali, salt and ultraviolet rays, the weathering and carbonization of the structure surface can be prevented, the dust-proof and antifouling performance is good, and the durability of the surface strength of the concrete can be maintained.

Background
In China, the phenomena of rapid freezing and cracking of the concrete surface below-20 ℃ are quite common in the high-speed railway concrete structures of vast areas, two geothermal cross-temperature zones, south China, east China, west China and north China; the durability of bridges and infrastructure projects in harsh environments is more serious. Therefore, the protection work for the durability of the concrete is not slow enough. Currently, many scientists claim to prolong the service life of concrete engineering, and claim that the service life of a main bridge is designed according to 100-120 years, but the actual condition is far lower than the requirements. Therefore, how to solve the problem of the durability of the concrete is a problem of the research of experts and scholars of the world, and the urgency and the economical efficiency of the concrete are self evident.

The present invention is directed to a silicone polyethylene resin and a method for preparing the same, which solve the problems set forth in the background art.
In order to achieve the purpose, the invention provides the following technical scheme: the organosilicon polyethylene resin has the technical key points that: the composition comprises the following components in parts by mass:
preferably, the preparation method of the silicone polyethylene resin comprises the following steps:
step S1: the azodiisobutyronitrile is put into acetone and completely dissolved to obtain an azodiisobutyronitrile-acetone mixture;
step S2: 1/2 methanol, all vinyl acetate and tetramethylsiloxane are put into a reactor, the temperature is raised to 40-65 ℃, all azodiisobutyronitrile-acetone mixtures are put into the reactor for many times, the temperature is kept for 1-3 hours until the materials are reacted and are completely transparent;

The concrete and stone can be protected from the penetration and erosion of external water, acid, alkali, salt and ultraviolet rays, the weathering and carbonization of the structure surface can be prevented, the dust-proof and antifouling performance is good, and the durability of the surface strength of the concrete can be maintained.
Detailed Description
The invention is further illustrated by the following examples, without limiting the scope of the invention.
The invention provides a technical scheme that organic silicon polyethylene resin comprises the following components in parts by mass:
in the present embodiment, the preparation method of the silicone polyethylene resin comprises the following steps:
step S1: the azodiisobutyronitrile is put into acetone and completely dissolved to obtain an azodiisobutyronitrile-acetone mixture;
step S2: 1/2 methanol, all vinyl acetate and tetramethylsiloxane are put into a reactor, the temperature is raised to 40-65 ℃, all azodiisobutyronitrile-acetone mixtures are put into the reactor for many times, the temperature is kept for 1-3 hours until the materials are reacted and are completely transparent;
step S3: adding the rest methanol and the residual tetrachloroethylene into the reactor, and diluting the materials into a solution with the solid content of 25-45%;
step S4: adding dimethyl silicone oil into the reactor, and keeping the temperature for 30 min;
step S5: stopping reaction, cooling, filtering, discharging, and filling into a completely sealed iron pipe device to obtain a finished product.
The formulations of examples 1-3 are shown in Table 1.
TABLE 1 formulations of examples 1-3
The results of the mechanical property tests of examples 1-3 are shown in Table 2.
Table 2 results of mechanical property test of examples 1 to 3
The relationship of the change of the permeation resistance pressure of the concrete surface coated with different solid contents is shown in Table 3.
TABLE 3 relationship of the variation of the anti-seepage pressure of the concrete surface coated with different solid contents
The results of the freeze-thaw resistance test on the concrete surface coated with different solid contents are shown in Table 4.
TABLE 4 Freeze-thaw resistance test results of painted concrete surfaces with different solid contents
| Solid content coating (%) | Standard required value | Test results |
| Blank space | No crack at-35 ℃ | 3 test pieces have cracks or breakages at-35 DEG C |
| 25 | No crack at-35 ℃ | 3 test pieces have no crack at-35 DEG CLine(s) |
| 30 | No crack at-35 ℃ | 3 test pieces have no cracks at 35 ℃ below zero |
| 35 | No crack at-35 ℃ | 3 test pieces have no cracks at 35 ℃ below zero |
The above examples illustrate the invention in different proportions, but with no major changes. The key data are relatively close and do not influence the essence of the material. It can also be seen that the higher the solids content the lower the permeation resistance pressure begins, because the dryness increases with time and the permeation resistance pressure increases gradually.
The invention relates to a surface penetrating type sealant, which takes industrial alcohol as a dielectric solution, and the components of the sealant mainly comprise organic silicon, vinyl acetate and butyl acrylate. The protective agent can be used for impregnating the concrete surface and the stone surface layer by 0.3mm and covering the surface to form a sealing layer to prevent permeation, but the appearance characteristic and the air permeability of the concrete are not changed. The concrete and stone can be protected from the penetration and erosion of external water, acid, alkali, salt and ultraviolet rays, the weathering and carbonization of the structure surface can be prevented, the dust-proof and antifouling performance is good, and the durability of the surface strength of the concrete can be maintained.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein, and any reference thereto is therefore intended to be embraced therein.
Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
