Embodiment １

[0018] (1) Dissolve 2g of chitosan powder in 50mL of 4% lactic acid aqueous solution, heat to 40°C to completely dissolve chitosan, and add 10mL of bronopol solution with a mass concentration of 2% to mix evenly, then Add dropwise 10mL0.5g / 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 8% lactic acid aqueous solution, 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 12mL0.6g / 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 of chitosan powder in 50mL of 12% aqueous lactic acid solution, heat to 60°C to completely dissolve the chitosan, and add 10mL of bronopol solution with a mass concentration of 6% to mix evenly, then Add dropwise 14mL0.7g / 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 .

Abstract

The invention discloses high-strength high-softness high-antibacterial-performance paper for daily use and a preparation method thereof. According to the method, chitosan powder is dissolved in a lactic acid water solution, chitosan is completely dissolved, a bronopol solution is added into the mixture to be evenly mixed, then a negative ion polyacrylamide solution is dripped, a lactic acid / chitosan-bronopol nano microsphere compound is prepared through reaction, the obtained compound is sprayed to the surface of paper for daily use, and then the high-strength high-softness high-antibacterial-performance paper for daily use is obtained. By the utilization of the lactic acid / chitosan-bronopol nano microsphere compound, the paper for daily use has high strength, high antibacterial performance and high softness, the three defects that according to common paper for daily use, strength and softness are low, and no antibacterial performance exists are overcome, and high application value is obtained.

Description

technical field [0001] The invention relates to a new type of household paper, in particular to a high-strength, high-softness, high-antibacterial household paper and a preparation method thereof. Background technique [0002] Paper products are indispensable products in people's production and life. The fibers in paper can absorb many microorganisms, and these microorganisms will multiply rapidly if the temperature is appropriate, and then cause various hazards to the human body. Especially household paper, which is the most commonly used in people's daily life, is likely to bring the chance of bacterial transmission or cross-infection. At present, the main household papers generally have the disadvantages of low strength, poor softness and no antibacterial properties. Therefore, in order to prevent the spread of harmful bacteria and various infectious diseases caused by cross-infection during the use of paper products, and to protect human health, it is of great significa...
