[0102] Test example

[0103] The home decoration plates prepared in the above examples and comparative examples are tested for performance:

[0104] (1) Antiviral performance: The antiviral activity of the home decoration plates prepared in Examples 1-6 and Comparative Examples 1-4 is determined according to standard ISO 21702-2019, and the test results are shown in Table 1:

[0105] Table 1

[0106]

[0107] (2) Antibacterial performance: The bacteriostatic rate of the home decoration plates prepared in Examples 1-6 and Comparative Examples 1-4 is determined according to standard QB / T4371-2012 "Evaluation of Furniture Antimicrobial Performance Appendix B Film Method", the action time is 24h, and the test results are shown in Table 2:

[0108] Table 2

[0109]

[0110] (3) Negative oxygen ion release performance: The air negative ion concentration of the house decoration plate prepared in Examples 1-6 and Comparative Examples 1-4 was determined according to the standard JC / T2110-2012 "Indoor air ion concentration test method", and the test results are shown in Table 3:

[0111] Table 3

[0112] Example 1 Example 2 Example 3 Example 4 Example 5 Example 6 Comparative Example 1 Comparative Example 2 Comparative Example 3 Comparative Example 4 Air negative ion concentration average value (ions / cm3) 2098 2182 1052 1052 1082 3278 5276 2527 8278

[0113] As can be seen from Table 1, Table 2 and Table 3, the house decoration plate prepared in the present application has good antiviral performance, antibacterial performance and can release a large amount of negative oxygen ions. The nano silicon sheet is taken from natural inorganic bentonite or attapulgite, which is separated layer by layer into a sheet by delamination technology, and is rich in a large amount of negative charge. The exposed negative charge can form strong adsorption force, so that the positively charged bacteria, viruses or odor are adsorbed to the surface of the nano silicon sheet. By using the mechanism of adsorbing harmful molecules and anti-sticking of natural silicon sheet, the special effects of environmental purification, antibacterial and mildew resistance, dust and odor removal, and ultraviolet resistance can be achieved, and the growth of bacteria can be effectively prevented, and the environmental quality can be purified. Compared with Example 1, in Comparative Example 1, no nano silicon sheet was added, and the antiviral performance, antibacterial performance and negative oxygen ion release capacity were significantly reduced; in Comparative Example 2, no flame retardant 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide was added, and the antiviral performance, antibacterial performance and negative oxygen ion release capacity were not affected; in Comparative Example 3, no inorganic reinforcing filler glass fiber was added, and the antiviral performance, antibacterial performance and negative oxygen ion release capacity were not affected; in Comparative Example 4, no coupling agent γ-(methacryloyloxy) propyl trimethoxysilane was added, and the dispersibility of the nano silicon sheet was reduced, and the antiviral performance, antibacterial performance and negative oxygen ion release capacity were slightly reduced.

[0114] (4) Flame retardant performance: The limiting oxygen index of the house decoration plate prepared in Examples 1-6 and Comparative Examples 1-4 was determined according to the standard GB / T2406.1-2008 "Plastics - Determination of the flammability of plastics - Part 1: Ignition time (vertical method)", and the test results are shown in Table 4:

[0115] Table 4

[0116] Example 1 Example 2 Example 3 Example 4 Example 5 Example 6 Comparative Example 1 Comparative Example 2 Comparative Example 3 Comparative Example 4 Limiting oxygen index (%) 27.8 28.5 28.0 28.1 28.3 28.5 27.6 27.2 27.8 27.5

[0117] From Table 4, it can be seen that the house decoration plate prepared in the application has good flame retardant performance. The addition of the flame retardant can effectively improve the flame retardant performance of the house decoration plate. Compared with Example 1, in Comparative Example 1, no nano-silicon sheet is added, which mainly affects the antiviral performance, antibacterial performance and negative oxygen ion release capacity, and has no obvious influence on the flame retardant performance; in Comparative Example 2, no flame retardant 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide is added, and the flame retardant performance is obviously decreased; in Comparative Example 3, no inorganic reinforcing filler glass fiber is added, and the flame retardant performance is not obviously affected; in Comparative Example 4, no coupling agent γ-(methacryloyloxy) propyl trimethoxysilane is added, and the flame retardant performance is also not obviously affected.

[0118] (5) Mechanical properties: The tensile strength of the house decoration plate prepared in Examples 1-6 and Comparative Examples 1-4 was determined according to the standard GB / T1040.1-2006 "Determination of tensile properties of plastics Part 1: General principles", and the test results are shown in Table 5:

[0119] Table 5

[0120] Example 1 Example 2 Example 3 Example 4 Example 5 Example 6 Comparative Example 1 Comparative Example 2 Comparative Example 3 Comparative Example 4 Tensile strength (MPa) 82.3 83.6 82.5 82.9 83.1 83.3 80.4 82.2 78.8 81.7

[0121] From Table 5, it can be seen that the house decoration plate prepared in the application has good mechanical properties. The addition of the inorganic reinforcing filler can effectively improve the mechanical properties of the house decoration plate. Compared with Example 1, in Comparative Example 1, no nano-silicon sheet is added, and since the nano-silicon sheet is an inorganic material, it can help to improve the mechanical properties of the plate, and the tensile strength is decreased; in Comparative Example 2, no flame retardant 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide is added, and the mechanical properties are not obviously affected; in Comparative Example 3, no inorganic reinforcing filler glass fiber is added, and the mechanical properties are obviously decreased; in Comparative Example 4, no coupling agent γ-(methacryloyloxy) propyl trimethoxysilane is added, and the dispersion of the inorganic reinforcing filler is decreased, and the mechanical properties are decreased.

[0122] Although the embodiments of the application have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and alterations can be made without departing from the principles and spirit of the application, and the scope of the application is defined by the appended claims and their equivalents.
