Embodiment 1
[0012] Weigh 0.5 g of Nanda brand silica gel 703, 704, and 70 5 produced by Liyang Kangda Chemical Factory in a ratio of 1:1:1, and 100 ml of banana water. Completely dissolve 0.5 g of Nanda brand silica gel weighed according to the above ratio in 100 ml of banana water. Then, at room temperature, soak ordinary paper in the above solution for 10 seconds, take it out and dry it at low temperature (50 degrees) or dry it naturally at room temperature to obtain superhydrophobic, self-cleaning nanostructure surface paper. The specific measurement results are as follows: the super-hydrophobic angle is 155 degrees; it has the functions of writing, printing, copying and printing of ordinary paper; moisture-proof (water absorption, measurement unit: g / m 2 , testing basis (standard code) GB / T453-1989) performance: ordinary paper 82.8, similar nanostructure surface paper 48.6; printing surface strength (measurement unit: m / s, testing basis (standard code) GB / T2679.16-1997 ): Ordinary pa...
Embodiment 2
[0014] Weigh 0.5 g of Nanda brand silica gel 703, 704, and 705 at a ratio of 0.5:0.5:1, and 100 ml of ethyl acetate. Completely dissolve 0.5 g of Nanda brand silica gel weighed in the above ratio in 100 ml of ethyl acetate. Then, at room temperature, soak ordinary paper in the above solution for 15 seconds, take it out and dry it at low temperature (50 degrees) or dry it naturally at room temperature to obtain super-hydrophobic, self-cleaning nanostructure surface paper. The specific measurement results are as follows: the super-hydrophobic angle is 157 degrees; it has the functions of writing, printing, copying and printing of ordinary paper; moisture-proof (surface absorption weight, unit of measurement: g / m 2 , testing basis (standard code) GB1540-1989) performance: ordinary paper 21.3, similar nanostructure surface paper 11.6; Paper 2.00.
Embodiment 3
[0016] Nanda brand silica gel 703, 704, 705 weighed 0.5 g according to the ratio of 0.5:0.5:1, and 100 ml of n-butyl acetate. Completely dissolve 0.5 g of Nanda brand silica gel weighed in the above ratio in 100 ml of n-butyl acetate. Then, at room temperature, soak ordinary paper in the above solution for 12 seconds, take it out and dry it at low temperature (50 degrees) or dry it naturally at room temperature to obtain superhydrophobic, self-cleaning nanostructure surface paper. The specific measurement results are as follows: the super-hydrophobic angle is 155 degrees; it has the functions of writing, printing, copying and printing of ordinary paper; moisture-proof (surface absorption weight, unit of measurement: g / m 2 , testing basis (standard code) GB1540-1989) performance: ordinary paper 21.3, similar nanostructure surface paper 12.0; Paper 2.02.
