Embodiment 1

[0014] A method for making carbon paper, comprising the steps of:

[0015] In the first step, mix 2g of chlorinated polyethylene, 2g of ethylene, 7g of orthosilicate, 2g of barium sulfate, 3g of aniline, 4g of bentonite, 12g of sodium phosphate, 3g of beeswax and 2g of calcium chloride, and put them into a high-pressure reactor with a pressure of 100mpa. , reacted for 1 hour.

[0016] The second step is to take it out and cool it, and grind it to a particle size of 100 microns.

[0017] The third step is to irradiate under ultraviolet light for 1 day.

[0018] The fourth step, add 2g of indigo for mixing, then add lead chloride and ethanol to fully dissolve.

[0019] The substance obtained in the fifth step and the fourth step is evenly applied on the non-woven fabric, dried in the shade, and obtained.

Embodiment 2

[0021] A method for making carbon paper, comprising the steps of:

[0022] In the first step, mix 12g of chlorinated polyethylene, 8g of ethylene, 13g of orthosilicic acid, 10g of barium sulfate, 7g of aniline, 13g of bentonite, 16g of sodium phosphate, 9g of beeswax and 5g of calcium chloride, and put them into a high-pressure reactor with a pressure of 137mpa , reacted for 9 hours.

[0023] The second step is to take it out and cool it, and grind it to a particle size of 200 microns.

[0024] The third step is to irradiate under ultraviolet light for 2 days.

[0025] The fourth step, add 3g of indigo for mixing, then add lead chloride and ethanol to fully dissolve.

[0026] The substance obtained in the fifth step and the fourth step is evenly applied on the non-woven fabric, dried in the shade, and obtained.

Embodiment 3

[0028] A method for making carbon paper, comprising the steps of:

[0029] In the first step, mix 11g of chlorinated polyethylene, 3g of ethylene, 10g of orthosilicic acid, 3g of barium sulfate, 6g of aniline, 5g of bentonite, 14g of sodium phosphate, 4g of beeswax and 4g of calcium chloride, and put them into a high-pressure reactor with a pressure of 127mpa , reacted for 5 hours.

[0030] The second step is to take it out and cool it, and grind it to a particle size of 170 microns.

[0031] The third step is to irradiate under ultraviolet light for 1-2 days.

[0032] The fourth step, add 3g of indigo for mixing, then add lead chloride and ethanol to fully dissolve.

[0033] The substance obtained in the fifth step and the fourth step is evenly applied on the non-woven fabric, dried in the shade, and obtained.

Abstract

Disclosed is a carbon paper manufacturing method. The method includes the following steps that 2-12 g of chlorinated polyethylene, 2-8 g of ethylene, 7-13 g of metasilicic acid, 2-10 g of barium sulfate, 3-7 g of aniline, 4-13 g of bentonite, 12-16 g of sodium phosphate, 3-9 g of beewax and 2-5 g of calcium chloride are mixed uniformly and put in a high pressure reactor, the pressure is 100-137 mpa, and the reaction time lasts one to nine hours; a product obtained in the former step is taken out, cooled and ground until the particle size reaches 100-200 micrometers; the product is irradiated for one to two days under an ultraviolet lamp; 2-4 g of indigo blue is added for mixing, and then lead chloride and ethyl alcohol are added and fully dissolved to obtain a substance; and the obtained substance is uniformly smeared on non-woven fabrics to be dried in the shade so as to obtain carbon paper. According to the method, burdening is simple, the obtained carbon paper is not prone to fading, and colors are not prone to contaminating hands during usage.

Description

technical field [0001] The invention belongs to the field of materials, in particular to a method for making carbon paper. Background technique [0002] Carbon paper is a common office product, but its surface is often easy to decolorize, and hands are easy to rub the paint on it and need to wash hands frequently. Moreover, pigments usually have powder, which can also affect respiratory health. Contents of the invention [0003] The object of the present invention is to provide a method for making carbon copy paper, which is not easy to rub against the hands during use, reduces inhalable powder, has a simple production method, and can preserve the copied handwriting for a long time. [0004] The technical solutions adopted are: [0005] A method for making carbon paper, comprising the steps of: [0006] The first step, chlorinated polyethylene 2-12g, ethylene 2-8g, orthosilicate 7-13g, barium sulfate 2-10g, aniline 3-7g, bentonite 4-13g, sodium phosphate 12-16g, beeswax...
