preparation example Construction

[0036] Such as figure 1 As shown, the embodiment of the present invention provides a preparation method of thermal insulation coating, which is a preparation method of the above thermal insulation coating, and the preparation method of the thermal insulation coating includes the following steps:

[0037] Step S110: Soak the polyvinyl alcohol in water for 24 hours, add an appropriate amount of defoamer, and steam under high pressure until it boils for 6 hours and cool for later use.

[0038] Step S120: add an appropriate amount of warm water into the reactor, soak the asbestos wool for 10 hours, add penetrant, industrial salt, glass oxide, and dispersant, stir repeatedly for 3 hours, and then add polyacrylamide.

[0039] Step S130: After the asbestos fiber becomes fine, add vitrified perlite and water repellent and stir repeatedly for 9 hours, let stand for 10 hours, and then stir again for 5 hours to complete.

[0040] The preparation method of the thermal insulation coating ...

Embodiment 1

[0043] Weigh the following components in parts by mass: 30 parts of asbestos wool, 80 parts of vitrified perlite, 0.8 part of foaming agent, 0.5 part of dispersant, 0.3 part of defoamer, 30 parts of zirconia, 20 parts of polyvinyl alcohol, 3 parts of water repellent, 2 parts of salt, 0.3 parts of pigment, 3 parts of whitening agent, 0.3 parts of polyacrylamide and 250 parts of water. Wherein, the antifoaming agent is silicone.

[0044] The thermal insulation coating of Example 1 was painted on the surface of the building with a coating thickness of 2 mm. After drying, a thermal insulation coating was formed. The thermal conductivity of the thermal insulation coating of Example 1 was tested by the EN12664 measurement method. Among them, the thermal conductivity directly reflects the thermal insulation effect of the thermal insulation coating. The thermal conductivity of the thermal insulation coating formed by the thermal insulation coating in Example 1 is shown in Table 1.

Embodiment 2

[0046] Weigh the following components in parts by mass: 50 parts of asbestos wool, 100 parts of vitrified perlite, 1 part of foaming agent, 0.8 part of dispersant, 0.5 part of defoamer, 38 parts of zirconia, 25 parts of polyvinyl alcohol, 3.3 parts of water repellent, 2.5 parts of salt, 0.5 parts of pigment, 3.5 parts of whitening agent, 0.5 parts of polyacrylamide and 300 parts of water. Wherein, the antifoaming agent is silicone.

[0047] The thermal insulation coating of Example 2 was painted on the surface of the building with a coating thickness of 2 mm. After drying, a thermal insulation coating was formed. The thermal conductivity of the thermal insulation coating of Example 2 was tested by the EN12664 measurement method. Among them, the thermal conductivity directly reflects the thermal insulation effect of the thermal insulation coating. The thermal conductivity of the thermal insulation coating formed by preparing the thermal insulation coating in Example 2 is shown...

Abstract

The invention relates to heat insulation paint, a preparation method of the heat insulation paint and a heat insulation coating thereof. The heat insulation paint is prepared from the following ingredients in parts by mass: 30 to 80 parts of asbestos wool, 80 to 120 parts of vitrified perlite, 0.8 to 1.2 parts of foaming agents, 0.5 to 1 part of dispersing agents, 0.3 to 0.8 part of antifoaming agents, 30 to 40 parts of zirconia, 20 to 30 parts of polyvinyl alcohol, 3 to 4 parts of moisture repellents, 2 to 3 parts of salt, 0.3 to 0.8 part of pigment, 3 to 4 parts of brightening agents, 0.3 to0.8 part of Polyacrylamide and 250 to 350 parts of water, wherein through the vitrified perlite, the heat insulation coating obtained by the heat insulation paint is of a porous structure, so that space steric hindrance is formed in the heat insulation coating; the heat conduction can be blocked through the space steric hindrance, so that the heat loss is reduced; therefore the heat insulation and thermal isolation of the heat insulation coating can be realized.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a thermal insulation coating, a preparation method thereof and the thermal insulation coating. Background technique [0002] Making buildings thermally insulated can not only save energy, but also improve the quality of living. According to statistics, the proportion of building energy consumption in the entire energy consumption is generally 30% to 40%, and most of it is energy consumption in heating and cooling. As an important part of building energy conservation, thermal insulation coatings have become It is a hot topic of industry research and is valued by countries all over the world. However, the thermal insulation effect of existing thermal insulation coatings is still relatively poor and cannot meet people's needs. Contents of the invention [0003] In order to solve the above technical problems, an embodiment of the present invention provides a ther...
