Performance test
Taking an iron plate for manufacturing a lamp housing, wherein the thickness of the iron plate is 6mm, the two sides of the iron plate are coated with the heat insulation coating in the step S1 of each embodiment and each comparative example, the coating thickness and the drying temperature are set according to the step S2, a YBF-3 heat conductivity coefficient tester is used for testing the heat conductivity coefficient of each iron plate, and the test results are shown in Table 2.
Taking an iron plate for lamp housing manufacture, the thickness of the iron plate was 6mm, both sides of the iron plate were coated with the thermal barrier coating in step S1 of each of examples and comparative examples of the present application, and the coating thickness and baking temperature were set in accordance with step S2, and each iron plate was subjected to adhesion test in accordance with GB 1720-.
Taking an iron plate and glass for manufacturing a lamp housing, wherein the thicknesses of the iron plate and the glass are both 6mm, the two surfaces of the iron plate are coated with the heat insulation coating in the step S1 of each example and each comparative example, the coating thickness and the drying temperature are set according to the step S2, then the iron plate and the glass are bonded through a neutral silicone glass adhesive, and the iron plate and the glass are subjected to tensile shear strength tests according to the determination of tensile shear strength of the adhesive (rigid material to rigid material) in GB/T7124 & 2008, and the test results are shown in Table 2.
TABLE 2
| Thermal conductivity W/(m.K) | Grade of adhesion | Tensile shear strength Mpa | |
| Example 1 | 3.9 | First stage | 1.6 |
| Example 2 | 4.0 | First stage | 1.8 |
| Example 3 | 3.7 | First stage | 1.6 |
| Example 4 | 4.2 | Second stage | 1.7 |

| Comparative example 3 | 9.8 | First stage | 1.4 |
| Comparative example 4 | 8.8 | Three-stage | 1.4 |
As can be seen from table 2, the thermal conductivity of comparative examples 1 and 4 is higher than that of example 3, and the adhesion rating is lower than that of example 3, which indicates that the addition of polymethylsilsesquioxane and cenospheres can improve the heat-insulating property and durability of the coating on the premise of the addition of epoxy resin, because the styrene-acrylic emulsion and epoxy resin form an interpenetrating network for stable arrangement and dispersion of the cenospheres and polymethylsilsesquioxane in the network, and both the cenospheres and polymethylsilsesquioxane have good strength, thereby improving the film-forming strength of the styrene-acrylic emulsion, improving the adhesion of the coating, improving the protection degree of the iron plate, and prolonging the service life of the lamp housing.
The thermal conductivity of comparative example 2 and comparative example 3 is higher than that of example 3, namely the thermal insulation performance of example 3 is better, which shows that the effect of the combination of the cenospheres and the polymethylsilsesquioxane is better than the effect of the single use of the cenospheres or the single use of the polymethylsilsesquioxane.
The heat conductivity coefficients of the examples 4-5 are all higher than that of the example 3, and the adhesion rating is lower than that of the example 3, namely the heat insulation performance and the durability of the coating of the example 3 are better, probably because the addition of the zinc gray iron titanium powder as an antirust filler can improve the antirust effect of the coating, but the heat conductivity of the zinc gray iron titanium powder is high, so the heat insulation performance of the coating is influenced, and in addition, the zinc gray iron titanium powder is not good in dispersibility in a system consisting of the styrene-acrylic emulsion and the epoxy resin, so the adhesion of the coating is reduced.
The thermal conductivity of examples 6-7 was lower than that of example 3, i.e., the coatings of examples 6-7 had better thermal insulation performance, probably because the sodium hydroxide etched the surface of the cenospheres, resulting in increased defects on the surface of the cenospheres, which caused repeated reflection and scattering of heat entering the coating, thereby reducing the amount of heat passing through the coating and improving the thermal insulation performance.
Example 8 has a lower thermal conductivity than example 5 and a higher adhesion level than example 5, i.e., the coating of example 8 has better thermal insulation performance and durability, probably because the zinc gray ferrotitanium powder is doped into the defects of the cenospheres, and the thermal conductivity of the zinc gray ferrotitanium powder further promotes the repeated reflection and scattering of heat entering the coating in the defects of the cenospheres, thereby improving the thermal insulation performance; in addition, the hollow microspheres provide attachment for the zinc-gray iron-titanium powder, and the dispersibility of the zinc-gray iron-titanium powder is improved, so that the adhesive force of the coating is improved.
The examples 9-10 have a lower thermal conductivity than example 8, and the tensile shear strength of the iron plate and the glass is higher than that of the coating of example 8, i.e., the coatings of examples 9-10 have better thermal insulation performance and adhesion to neutral silicone glass cement, probably because the KH-570 modifies the surface of the hollow microspheres to improve the dispersibility of the hollow microspheres, thereby improving the thermal insulation effect, and in addition, when the neutral silicone glass cement is cured, the end of the KH-570 is bonded to the neutral silicone glass cement to improve the adhesion strength of the coating to the neutral silicone glass cement, thereby further improving the structural stability and durability of the lamp envelope.
The present embodiment is only for explaining the present application, and it is not limited to the present application, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present application.
