In addition, nitrocotton is a very dangerous chemical, which is formed by mixing cotton fibers with nitric acid. The danger is mainly that the fire-resistant and explosion-resistant protective material is inflammable, explosive and extremely toxic, and especially the accident is easier to happen in a high-temperature environment in summer. Once nitrocotton encounters a fire source or is subjected to external forces such as friction, impact and the like, explosion accidents can be caused, and great harm is brought to the surrounding environment and people.

Experimental example
The performance of the aqueous inks prepared in examples and comparative examples was tested in this test example, and is shown in tables 1 and 2. Wherein:
the film base material is a CPP film;
the test basis for the attachment fastness is: GB/T13217.7-2008;
the test basis of dynamic/static friction coefficient is: GB/T10006-2021.
TABLE 1
As can be seen from Table 1 above, examples 1-3 differ in the aqueous polyurethane resin selected. The aqueous polyurethane resin-1 (WPU 2365) selected in example 1 had good adhesion strength to the film substrate, and did not exhibit the phenomenon of melting ink when heat-sealed for 120℃0.5 seconds, 160℃0.5 seconds, and 180℃0.5 seconds, and had low dynamic and static friction coefficients.
The adhesive strength of the aqueous polyurethane resin-2 (50K 06) selected in the example 2 and the aqueous polyurethane resin-3 (R8302) selected in the example 3 on the film substrate is poor, wherein the ink melting phenomenon occurs in the example 2 when the heat sealing is carried out at 160 ℃/0.5 seconds and 180 ℃/0.5 seconds, the ink melting phenomenon occurs in the example 3 when the heat sealing is carried out at 120 ℃/0.5 seconds, 160 ℃/0.5 seconds and 180 ℃/0.5 seconds, and the dynamic friction coefficient and the static friction coefficient are both high.
Examples 4-6 differ from example 1 in that the aqueous acrylic emulsion selected was one that, as can be seen, example 1, the aqueous acrylic emulsion-1 (SEACRYL 11K 16) selected was excellent in high temperature resistance and was able to withstand the heat sealing operation of 120℃for 0.5 seconds, 160℃for 0.5 seconds, 180℃for 0.5 seconds; the aqueous acrylic emulsion-2 (B-6434A) selected in example 4, the aqueous acrylic emulsion-3 (B-8224A) selected in example 5, and the aqueous acrylic emulsion-4 (Joncryl 90 AP) selected in example 6 were inferior in heat resistance, could not withstand the heat sealing operation of 120℃or higher/0.5 seconds, and were high in both dynamic friction coefficient and static friction coefficient.
From the above, it can be seen from the data in table 1 that the aqueous ink prepared by using aqueous polyurethane resin-1 (WPU 2365) and aqueous acrylic emulsion-1 (seary 11K 16) as the main binders has excellent high temperature heat sealing performance and low friction coefficient performance.
TABLE 2
As can be seen from Table 2 above, comparative examples 1-2 differ from example 1 in that the amount of aqueous polyurethane resin-1 (WPU 2365) selected was outside the scope of the present invention (less than 20%). The results showed that comparative examples 1-2 showed poor adhesion strength to the film substrate, wherein comparative example 1 exhibited melting ink at 180 deg.c/0.5 seconds for heat sealing, and comparative example 2 exhibited melting ink at 160 deg.c/0.5 seconds for heat sealing and 180 deg.c/0.5 seconds for heat sealing.
Comparative example 3 differs from example 1 in that the amount of aqueous acrylic emulsion-1 (SEACRYL 11K 16) selected is not within the scope of the invention (below 15%). The results show that comparative example 3 is inferior in high temperature resistance and shows an ink melting phenomenon at 160℃C.0.5 seconds and 180℃C.0.5 seconds of heat sealing.
Comparative example 5, comparative example 7, comparative example 9 differ from example 1 in that the amount of aqueous acrylic emulsion-1 (SEACRYL 11K 16) selected is outside the scope of the present invention (above 30%), which would result in a decrease in the compatibility of aqueous polyurethane resin-1 (WPU 2365) in the ink system, which would affect the curing of aqueous polyurethane resin-1 (WPU 2365) into a film, which would result in a decrease in the adhesive strength to the film substrate, and which would not allow heat sealing at 180 ℃/0.5 seconds.
From the above, it can be seen from the data of table 2 that when the amount of the aqueous urethane resin-1 (WPU 2365) selected is within the range of the present invention (20% -35%) and the amount of the aqueous acrylic emulsion-1 (seary 11K 16) selected is within the range of the present invention (15% -30%), for example, the aqueous inks prepared in example 1 and comparative examples 4, 6 and 8 have excellent high temperature resistance, can be heat sealed at a high temperature of 180 ℃/0.5 seconds, and have excellent low friction coefficient properties.
The high-temperature-resistant low-friction-coefficient water-based ink prepared by the invention can be suitable for gravure printing, and has good adhesive strength on film substrates such as CPP, PE, PET; the layering sense stereoscopic effect of the printed patterns is excellent, the transition printing effect of the deep and shallow screens is excellent, and the layering plate color register printing effect is exquisite; compared with the traditional solvent type ink prepared by polyamide resin and nitrocotton liquid, the solvent type ink meets the requirements of safety and environmental protection, and the excellent performance can meet the requirements of paper towel packaging and printing.
