Embodiment 1
[0026] This embodiment is a fluorescent polyamide hot-melt adhesive, the raw material components of which are: primary diamine and bisacrylamide, wherein the molar ratio of primary diamine to bisacrylamide is 1:1.125.
[0027] The preparation method of this embodiment:
[0028] Dissolve 12.33g of N,N'-methylenebisacrylamide in 60mL of methanol and 30mL of water and add 12.98g of 1.8-octanediamine, wherein N,N'-methylenebisacrylamide and 1.8-octanediamine The molar ratio is 1:1.125. The mixed solution was stirred at 30° C. for 24 h, and then the reacted solution was precipitated in acetone to obtain a white solid, which was a hyperbranched polyamide. It is dissolved in methanol to ensure that the mass concentration of the dissolved hyperbranched polyamide solution is 15%, and cast at room temperature to form a film.
[0029] The resulting thin film fluoresces blue under 365nm ultraviolet light. The transparent film is sandwiched between two aluminum plates, and the aluminum ...
Embodiment 2
[0033] This embodiment is a fluorescent polyamide hot-melt adhesive, the raw material components of which are: primary diamine and bisacrylamide, wherein the molar ratio of primary diamine to bisacrylamide is 1:1.
[0034] The preparation method of this embodiment:
[0035] After dissolving 12.33g of N,N'-methylenebisacrylamide in 60mL of methanol and 30mL of water, 7.05g of 1,4-butanediamine was added. The molar ratio of N,N'-methylenebisacrylamide to 1,4-butanediamine is 1:1. The mixed solution was stirred at 30° C. for 20 h, and then the reacted solution was precipitated in acetone to obtain a light yellow solid, which was a hyperbranched polyamide. It is dissolved in methanol to ensure that the mass concentration of the dissolved hyperbranched polyamide solution is 20%, and cast at room temperature to form a film.
[0036] The resulting film fluoresced blue under 365 nm ultraviolet light. The transparent film is sandwiched between two aluminum plates, and the aluminum p...
Embodiment 3
[0038] A fluorescent polyamide hot-melt adhesive, the raw material components of which are: dibasic primary amine and bisacrylamide, wherein the molar ratio of dibasic primary amine to bisacrylamide is 1:1.5.
[0039]After dissolving 13.46g of N,N'-vinylbisacrylamide in 70mL of methanol and 35mL of water, 44.1g of 4,7,10-trioxy-1,13-tridecanediamine was added. The molar ratio of N,N'-vinylbisacrylamide to 4,7,10-trioxy-1,13-tridecanediamine is 1:1.5. Stir the mixed solution at 30°C for 30 hours, then precipitate the reacted solution in acetone to obtain a white solid, which is a hyperbranched polyamide, which is dissolved in methanol to ensure hyperbranched polyamide after dissolution The mass concentration of the polyamide solution is 15%, and the film is cast at room temperature.
[0040] The resulting film fluoresced blue under 365 nm ultraviolet light. The transparent film is sandwiched between two aluminum plates, and the aluminum plates are heated at 160°C for 60 minut...
