[0027] A kind of preparation technology of double-sided adhesive tape of tissue paper, this double-sided adhesive tape comprises base material 1, both surfaces of base material 1 are all coated with adhesive agent, forms adhesive agent layer 2, the other side of adhesive agent layer 2 The side is covered with release paper 3;
[0028] Wherein, substrate 1 adopts modified tissue paper, and described modified tissue paper is prepared by the following method:
[0029] S1. Add 0.5g bamboo fiber to 100mL ethanol, add 0.5-0.6g sodium hydroxide under the condition of slow stirring, then put it in a constant temperature water bath at 60℃ and stir, and add 0.5-0.6mL of 2,3-cyclo Oxypropyltrimethylammonium chloride, reacted for 2h, and repeatedly washed the product to neutrality to obtain modified bamboo fiber;
[0030] S2. Take 500mL of dimethyl sulfoxide, 1g of aramid fibers, and 1.5g of sodium hydroxide and add them into a beaker, stir magnetically at room temperature for 5-6d to ob...

[0044] Modified cotton paper is prepared by the following method:
[0045] S1. Add 0.5g of bamboo fiber to 100mL of ethanol, add 0.5g of sodium hydroxide under slow stirring conditions, then place it in a constant temperature water bath at 60°C to stir, and add 0.5mL of 2,3-epoxypropyltri Methylammonium chloride, reacted for 2h, and washed the product repeatedly to neutrality to obtain modified bamboo fiber;
[0046] S2. Take 500mL of dimethyl sulfoxide, 1g of aramid fibers, and 1.5g of sodium hydroxide into a beaker, stir magnetically at room temperature for 5 days to obtain aramid nanofiber suspension, wash with acetone for 5 times and separate, then vacuum dry at room temperature Obtain aramid fiber nanofiber powder;
[0047] S3. Add aramid nanofiber powder into distilled water to prepare a suspension with a mass fraction of 0.2%, immerse the modified bamboo fiber in the prepared suspension, ultrasonically disperse for 30 minutes, rinse with deionized water for 5 times, an...
Embodiment 2
[0050] Modified cotton paper is prepared by the following method:
[0051] S1. Add 0.5g bamboo fiber to 100mL ethanol, add 0.6g sodium hydroxide under the condition of slow stirring, then put it in a constant temperature water bath at 60℃ and stir, and add 0.6mL of 2,3-epoxypropyltri Methylammonium chloride, reacted for 2h, and washed the product repeatedly to neutrality to obtain modified bamboo fiber;
[0052] S2. Take 500mL of dimethyl sulfoxide, 1g of aramid fiber, and 1.5g of sodium hydroxide into a beaker, and stir magnetically at room temperature for 6 days to obtain aramid nanofiber suspension, which is washed with acetone for 7 times and separated, then vacuum-dried at room temperature Obtain aramid fiber nanofiber powder;
[0053] S3, adding aramid nanofiber powder into distilled water to prepare a suspension with a mass fraction of 0.2%, immersing the modified bamboo fiber in the prepared suspension, ultrasonically dispersing for 40 minutes, washing with deionized ...
