Performance test Using a steel plate (150 mm. times.70 mm. times.1 mm) as a substrate, after surface treatment, the coatings prepared in examples 1 to 15 and comparative examples 1 to 4 were sprayed on the surface of the steel plate as a test plate at a coating thickness of 10 to 300. mu.m. After the test boards were maintained for a certain period of time, performance tests were carried out according to the following test standards, the results of which are shown in Table 4.
Incombustibility grade: the grade A1 is higher than the grade B1 by detection according to GB 8624-; after the test board is maintained for 168 hours, QUV artificial aging test is carried out: JG/T224-2007, the longer the time, the better the ultraviolet resistance;

the test board was cured for 168h and then tested for thermal conductivity: the heat conductivity is measured by a heat conductivity tester, and the smaller the heat conductivity coefficient is, the better the heat insulation effect is;
and (3) carrying out an adhesive force hundred-grid test after the test board is maintained for 48 h: GB/T9286-1998, the grade is 0-5, and the 0 grade adhesion is the best;
and (3) drawing test: referring to GB/T9286-1998 standard, a higher pulling force means a stronger bond strength with the substrate.
Data analysis
Table 4: each test index of the coatings under examples 1 and 7-8
Combining table 4, example 1 and examples 7-8, it can be seen that: the grade of incombustibility of example 1 was grade A1, which was the same as the grade of incombustibility of examples 7 to 8 and the same as the QUV artificial aging time, respectively. However, in example 1, after the paint is coated on the substrate 168h, the neutral salt spray resistance of the paint is tested, and the result shows that the paint does not corrode and absorb moisture in 2000h, while in examples 7-8, the paint is corroded and absorbs moisture in 500 h. The QUV artificial aging time of example 1 is 8000h, and the QUV artificial aging times of examples 7-8 are not higher than 3500 h; more importantly, the thermal conductivity of example 1 is 0.2W/(m.k), while the thermal conductivity of example 7 is 0.4W/(m.k), and the thermal conductivity of example 8 is 0.5W/(m.k), both of which exceed the thermal conductivity of example 1; the adhesion of the embodiment 1 is optimally 0 grade, and the adhesion of the embodiments 7 and 8 is 2 grades; in addition, the drawing force of example 1 was 5MPa, and the drawing forces of examples 7 to 8 were all lower than 5 MPa; therefore, the change of the molar ratio of the anhydride to the primary amino siloxane has certain influence on the thermal conductivity, the adhesive force, the QUV artificial aging time and the drawing force of the coating, and particularly has great influence on the QUV artificial aging time and the adhesive force.
Table 5: each test index of the coatings of examples 1 to 6
In combination with Table 5 and examples 1 to 3, it can be seen that: the imide siloxane polymer in example 1 is prepared by reacting 3-aminopropyltriethoxysilane with anhydride, the imide siloxane polymer in example 2 is prepared by reacting 3-aminopropylmethyldimethoxysilane with anhydride, and the imide siloxane polymer in example 3 is prepared by reacting N-2-aminoethyl-3-aminopropylmethyldiethoxysilane with anhydride, so that the prepared coating has no difference in indexes such as incombustibility grade, QUV artificial aging time, adhesion grade, neutral salt fog resistance, thermal conductivity and drawing force, which indicates that the type of primary amino siloxane has no influence on the performance of the coating.
In example 1, the acid anhydride used to prepare the imidosiloxane polymer was trimellitic anhydride, in example 4, the acid anhydride used to prepare the imidosiloxane polymer was (-) -O-acetyl-L-malic anhydride, and in example 5, the acid anhydride used to prepare the imidosiloxane polymer was 1,2, 4-cyclohexanetricarboxylic anhydride, as can be seen in Table 5: the coatings prepared in examples 1 and 4 to 5 have no difference in the values of incombustibility, QUV artificial aging time, adhesion, neutral salt spray resistance, thermal conductivity and drawing force.
The molar ratio of the acid anhydride to the primary amino siloxane in example 1 was 0.6, and the molar ratio of the acid anhydride to the primary amino siloxane in example 6 was 0.3, as can be seen from Table 5: the indexes of incombustibility, QUV artificial aging time, adhesion, neutral salt spray resistance and pullout force of example 1 and example 6 are substantially not different, however, the thermal conductivity of example 1 is 0.2W/(m.k) and the thermal conductivity of example 6 is 0.24W/(m.k), i.e., the higher the molar ratio of acid anhydride to primary amino siloxane, the lower the thermal conductivity, and the better the heat retaining and insulating properties of the coating.
Table 6: each test index of the coatings under examples 1 and 9-12
Combining Table 6, example 1, and examples 9-12, it can be seen that: the values of the indexes of incombustibility grade, QUV artificial aging time, adhesion grade, neutral salt fog resistance and the like of the examples 1 and 9 to 10 are basically not different, however, the drawing force of the examples 9 and 10 is only 4MPa, and the thermal conductivity of the examples 10 is 0.28W/(m.k); in addition, the thermal conductivity in example 11 is 0.15W/(m.k), and the thermal conductivity in example 12 is 0.25W/(m.k), and it can be seen that the higher the total amount of silica aerogel, alumina hollow microspheres and glass hollow microspheres, the lower the thermal conductivity under certain conditions, and the stronger the heat insulating property and heat insulating property of the coating.
Table 7: each test index of the coatings under example 1 and comparative examples 1-3
By combining table 7, example 1 and comparative examples 1 to 3, it can be seen that: comparative example 1 using a methacrylic resin instead of the imide siloxane polymer, the paint prepared in comparative example 1 was rated B1 for incombustibility, which was lower than that of example 1, and in addition, the paint prepared in comparative example 1 had a QUV artificial aging time of only 800 hours, a neutral salt spray time of only 500 hours, a thermal conductivity of only 0.4W/(m · k), and adhesion and pullout force numbers lower than those of example 1. Therefore, the coating prepared in the embodiment 1 has excellent use effect no matter the coating is of a non-combustible grade, QUV artificial aging time, adhesive force grade, neutral salt fog resistance, heat conductivity and drawing force.
Comparative examples 2 and 3, both of which use imide siloxane polymers with percentages of addition outside the range of 30% to 70% as claimed in this application, are seen in table 7: the QUV artificial aging time of example 1 was 8000h, whereas those of comparative examples 2 and 3 were not more than 5000h, and example 1 was 2000h, comparative example 2 was 300h, and comparative example 3 was 1000, both of which were lower than those of example 1 in terms of the neutral salt spray index; likewise, the drawing force of comparative example 2 and comparative example 3 did not exceed 0.5MPa, which is much lower than the corresponding value of example 1.
More importantly, the thermal conductivity of comparative example 3 is 0.5W/(m.k), which is lower than 0.2W/(m.k) of example 1. it can be seen that varying the percentage of imide siloxane polymer addition affects some of the key performance criteria of the coating.
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.
