Abstract

The invention discloses carbon paper. The carbon paper comprises the following components: 2-17g of chlorinated polyethylene, 2-5g of polyethylene, 7-9g of poly-p-phenylenedimethanol, 2-6g of magnesium nitrate, 3-5g of carborundum, 4-9g of organic bentonite, 2-5g of calcium chloride and 2-5g of indigo blue, wherein the granularity of the 3-5g of carborundum is 100-200 microns. A manufacturing method comprises the following steps: uniformly mixing the chlorinated polyethylene, 2-5g of polyethylene, the poly-p-phenylenedimethanol, the magnesium nitrate, the organic bentonite and the calcium chloride to obtain a mixture, and putting the mixture into a high-pressure reaction kettle; cooling the taken mixture and grinding; carrying out insolation under the blazing sun; adding 2-5g of indigo blue, mixing, then adding alcohol, and fully dissolving; uniformly smearing substances obtained in the fifth step on a piece of paper, and drying in the shade so as to obtain the carbon paper. The carbon paper disclosed by the invention has the beneficial effects that the batching is simple, the obtained carbon paper is not easy to fade, the color is not easy to contact with the hands during use, and the hands do not need to be washed frequently; and the manufacturing method is simple, and rewritten words can be stored for long time.

Description

technical field [0001] The invention belongs to the field of materials, in particular to a carbon copy paper and a manufacturing method thereof. Background technique [0002] Carbon paper is a common office product, but its surface is often easy to decolorize, and the paint on it is easy to rub on the hands, so it needs to be washed frequently.
