Problems solved by technology

[0002] Copying refers to writing with carbon paper sandwiched between two or several sheets of paper. Several copies can be written at a time. Excessive force during the copying process causes other sheets placed below to be copied, and due to long-term multiple copying , causing the strength of the rewritten part to decrease, affecting the copying effect, and making the copy unclear

Abstract

The invention discloses high-strength carbon paper which is prepared from the following raw materials in parts by weight: 7 to 9 parts of sodium carboxymethylcellulose, 5 to 8 parts of titanium dioxide, 12 to 15 parts of polyamine polyepoxide resin, 3 to 5 parts of polyethylene glycol, 3 to 4 parts of sodium benzoate, 4 to 6 parts of borax, 13 to 18 parts of aramid fiber, 6 to 8 parts of light calcium carbonate, 6 to 7 parts of styrene-butadiene latex, 3 to 5 parts of coniferyl alcohol, 7 to 8 parts of sodium bicarbonate, 7 to 11 parts of corn starch, 4 to 6 parts of fatty acid, 6 to 8 parts of benzotriazole and 12 to 16 parts of pigment. The high-strength carbon paper disclosed by the invention has the advantages of clearness in duplication, good duplication effect, high strength of duplication area and no decoloring.

Description

technical field [0001] The invention relates to the technical field of office supplies, in particular to a high-strength copying paper. Background technique [0002] Copying refers to writing with carbon paper sandwiched between two or several sheets of paper. Several copies can be written at a time. Excessive force during the copying process causes other sheets placed below to be copied, and due to long-term multiple copying , causing the strength of the rewritten part to decrease, affecting the copying effect, and making the copy unclear. Contents of the invention [0003] In order to solve the above existing problems, the present invention provides a high-strength copying paper with clear copying, good copying effect, strong copying area, and no discoloration. [0004] The technical solution adopted by the present invention to solve the above-mentioned technical problems is: a kind of high-strength carbon copy paper, comprising the raw materials of the following weight...
