Embodiment 1

[0054] A multifunctional anti-heat radiation coating, from bottom to top, comprises a base coating of 0.3 mm, a thermal radiation protection coating of 2 μm and a wear-resistant coating of 0.3 mm;

[0055] The base coating includes the following components in parts by weight: 40 parts of polyether modified epoxy resin, 10 parts of titanium dioxide, 10 parts of hollow silica microspheres, 35 parts of water, 1.5 parts of defoamer, leveling 1.5 parts of agent and 2 parts of preservative;

[0056] The anti-heat radiation coating includes 4 layers of hollow silica microspheres with a particle size of 0.5 μm;

[0057] The wear-resistant coating includes the following components in parts by weight: 15 parts of zircon powder, 12 parts of diatomaceous earth, 36 parts of polyvinyl alcohol, 6 parts of sodium bentonite, 26 parts of water, 1.5 parts of defoamer, leveling 1.5 parts of the agent and 2 parts of the preservative.

[0058] The spraying process of the anti-heat radiation coati...

Embodiment 2

[0066] The difference between Example 2 and Example 1 is that step S4 is specifically: when the evaporation rate of the water in the base coating described in step S3 reaches 45-50%, the hollow silica microsphere particles The surface is coated with polyvinyl alcohol, and then sprayed onto the surface of the base coating to a thickness of about 2 μm. At this time, the number of layers of hollow silica microsphere particles is about 4 layers. Others are basically the same as those in Embodiment 1, and are not repeated here.

[0067] The test results are shown in Table 1. It can be seen that the exothermic radiation properties and adhesion of the steels sprayed with the multifunctional anti-heat radiation coating obtained in Examples 1 and 2 are significantly higher than the standard indicators, indicating that the present invention is more effective. The functional heat radiation protection coating has good heat radiation protection performance and good adhesion to steel. Afte...

Embodiment 3～9 and comparative example 1～4

[0071] Compared with Example 2, the multifunctional anti-heat radiation coatings provided in Examples 3-9 and Comparative Examples 1-4 are different in that the coating thickness and preparation conditions are shown in Table 2, and the others are basically the same as those in Example 1. are the same and will not be repeated here.

[0073]

[0074] Table 3 Test results of Examples 3 to 9 and Comparative Examples 1 to 4

[0075]

[0076]

[0077] It can be seen from Table 3 that the increase in the thickness of the anti-radiation coating helps to improve the anti-radiation performance of the steel, while the adhesion does not change much. With the increase of the particle size of the hollow silica microspheres, the thermal radiation resistance first increased and then decreased. This may be because the gap between the hollow silica microspheres is reduced if the particle size is too ...

Abstract

The invention provides a multifunctional anti-heat radiation coating and its spraying process on the steel surface. The anti-radiation coating includes a base coating, an anti-radiation coating and an abrasion-resistant coating, and the anti-radiation coating includes at least one layer of hollow silicon dioxide microsphere particles. First, clean and preheat the steel surface, and then spray the base coating on the surface. When the solvent in the base coating volatilizes to semi-dry, spray hollow silica microsphere particles on the surface, and finally spray the hollow silica microspheres on the surface. The particle surface is sprayed with wear-resistant coating. Wherein, the basic coating provides support for the adhesion of the heat-resistant radiation coating, and the wear-resistant coating can improve the wear resistance and service life of the coating. The heat-resistant radiation coating includes at least one layer of hollow silica microsphere particles, Utilizing the heat insulation effect of the hollow silica microsphere particles and the air filled between the hollow silica microsphere particles, the heat radiation protection effect of the coating is significantly enhanced.

Description

technical field [0001] The invention belongs to the technical field of anti-heat radiation coatings, and in particular relates to a multifunctional anti-heat radiation coating and a spraying process on the steel surface. Background technique [0002] With the rapid development of economy and society, the application field of steel is gradually expanding, such as widely used in building materials, household materials, road construction materials, etc. In particular, building materials receive strong radiation from the sun during use, resulting in a rise in surface temperature, and an increase in the temperature of building exterior walls, which leads to a rise in indoor temperature. In order to reduce the room temperature, people use a large number of sprinklers, electric fans, air conditioners, air conditioners, etc., which makes the energy consumption on the building increase sharply. This will not only bring economic losses, but also have great harm to the environment. T...
