Problems solved by technology

[0002] At present, the paper used for publishing, printing, news, office, etc. has the application properties of printable, writable, copyable, and printable. However, ordinary paper has insufficient hydrophobicity and is easy to be damp. After being damp, the strength will decrease, which will affect the printability. , Writable, copyable, printable performance
After searching, it has not been found that a layer of nanometer thickness and nanostructure particle surface is prepared on ordinary writable, printable, and printable paper, so that it not only has the writable, reproducible, printable, and printable functions of ordinary paper, It also has super-hydrophobic and self-cleaning properties; the printing surface strength is more than double that of similar products; the paper stretch rate is reduced by more than one-third; moisture-proof, durable and suitable for human observation, soft optical performance paper reports

Embodiment 1

[0012] Weigh 0.5 g of Nanda brand silica gel 703, 704, and 705 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 pap...

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: plain paper 21.3, similar nanostructured surface paper 11.6; transverse stretch rate (measurement unit: %, testing basis (standard code) GB459-1989): plain paper

[0015] 2.75, similar nano paper 2.00.

Embodiment 3

[0017] 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.

Abstract

An ultrahydrophobic self-cleaning paper with nano surface structure is made up by using silica gel (703,704, or 705), ethyl acetate, n-butyl acetate and banana oil to prepare an ultrahydrophobic self-cleaning nano layer on the surface of ordinary paper. Its advantages are high impressionability and writability, high water-proof and self-cleaning function.

Description

technical field [0001] The invention relates to industrial and civilian paper, in particular to super-hydrophobic and self-cleaning nanostructure surface paper used for publishing, printing, news and office. Background technique [0002] At present, the paper used for publishing, printing, news, office, etc. has the application properties of printable, writable, copyable, and printable. However, ordinary paper has insufficient hydrophobicity and is easy to be damp. After being damp, the strength will decrease, which will affect the printability. , Writable, copyable, printable performance. After searching, it has not been found that a layer of nanometer thickness and nanostructure particle surface is prepared on ordinary writable, printable, and printable paper, so that it not only has the writable, reproducible, printable, and printable functions of ordinary paper, It also has super-hydrophobic and self-cleaning properties; the printing surface strength is more than double...
