Embodiment 1
[0018] (1) Dissolve 2g chitosan powder in 50mL lactic acid aqueous solution with a volume concentration of 4%, heat to 40°C to completely dissolve chitosan, and add 10mL bronopol solution with a mass concentration of 2% to mix evenly, then Add dropwise 10mL 0.5g / L anionic polyacrylamide solution and react to prepare lactic acid / chitosan-bronopol nano-microsphere solution complex; the mass volume ratio of chitosan and lactic acid is 1g:1ml; chitosan The mass ratio of sugar to bronopol is 1:0.1;
[0019] (2) Spray the lactic acid / chitosan-bronopol nanosphere solution complex obtained in step (1) onto the surface of tissue paper, and dry it in an oven at 50°C for 10 minutes to obtain a high-strength, high-flexibility, and high-antibacterial Sex life paper. The spraying amount of lactic acid / chitosan-bronopol nano-microsphere solution complex on the surface of tissue paper is 0.1g / m 2 tissue paper.
Embodiment 2
[0021] (1) Dissolve 2g of chitosan powder in 50mL of lactic acid aqueous solution with a volume concentration of 8%, heat to 50°C to completely dissolve the chitosan, and add 10mL of bronopol solution with a mass concentration of 4% to mix evenly, then Add dropwise 12mL 0.6g / L anionic polyacrylamide solution and react to prepare lactic acid / chitosan-bronopol nano-microsphere solution complex; the mass volume ratio of chitosan and lactic acid is 1g:2ml; chitosan The mass ratio of sugar to bronopol is 1:0.2;
[0022] (2) Spray the lactic acid / chitosan-bronopol nanosphere solution complex obtained in step (1) onto the surface of tissue paper, and dry it in an oven at 50°C for 10 minutes to obtain a high-strength, high-flexibility, and high-antibacterial Sex life paper. The spraying amount of lactic acid / chitosan-bronopol nano-microsphere solution complex on the surface of tissue paper is 0.2g / m 2 .
Embodiment 3
[0024] (1) Dissolve 2g chitosan powder in 50mL lactic acid aqueous solution with a volume concentration of 12%, heat to 60°C to completely dissolve chitosan, add 10mL bronopol solution with a mass concentration of 6%, mix well, and then Add dropwise 14mL 0.7g / L anionic polyacrylamide solution and react to prepare lactic acid / chitosan-bronopol nano-microsphere solution complex; the mass volume ratio of chitosan and lactic acid is 1g:3ml; chitosan The mass ratio of sugar to bronopol is 1:0.3;
[0025] (2) Spray the lactic acid / chitosan-bronopol nanosphere solution complex obtained in step (1) onto the surface of tissue paper, and dry it in an oven at 50°C for 10 minutes to obtain a high-strength, high-flexibility, and high-antibacterial Sex life paper. The spraying amount of lactic acid / chitosan-bronopol nano-microsphere solution complex on the surface of tissue paper is 0.3g / m 2 .
