Example 13:

first, 20 cases obtained in examples 10 to 12 and comparative examples 4 to 6 were used for containing paper sheets made of the same material, and the cases were divided into two groups, each of which was 10 cases obtained in examples 10 to 12 and comparative examples 4 to 6:

the file boxes obtained in examples 10 to 12 and comparative examples 4 to 6 were placed in closets (material boxes) of different rooms, the environments of the two rooms were kept the same, and the humidity was 45%, and after 3 months of storage, the cases of mildew and worm were observed, and the results showed that the paper in the file box obtained in examples 10 to 12 did not mildew, the paper in the closet did not have worm, the paper mildew rate in the file box obtained in comparative example 4 was 9.2%, a large number of worms were present in the closet, the paper in the file box obtained in comparative example 5 did not mildew, a large number of worms were present in the closet, the paper mildew rate in the file box obtained in comparative example 6 was 43.4%, and a large number of worms were present in the closet; from the above, it can be seen that the anti-mold and anti-insect functions of the filing cases obtained in examples 10 to 12 are superior to the corresponding performances of the filing cases obtained in comparative examples 3 to 5.

II, limit oxygen index combustion test: the archive boxes obtained in examples 10 to 12 and comparative examples 4 to 6 were measured according to the GB/T2406.2-2009 standard, which specifies that the test can maintain the minimum oxygen concentration required for the combustion of the sample in a mixed gas flow of oxygen and nitrogen, and is defined as a limiting oxygen index, and the specific operating method was carried out according to the standard, and the test data are shown below.

	Example 10	Example 11	Example 12	Comparative example 4	Comparative example 5	Comparative example 6
							Limiting oxygen index	29.4%	31.6%	33.1%	22.9%	30.8%	17.4%

From the above data it can be seen that the flame retardant properties of the archival boxes obtained in examples 10-12 are superior to the corresponding properties of the archival boxes obtained in comparative examples 4, 6.
