Abstract

The invention discloses a writing duplicating paper. The writing duplicating paper is prepared from 6-10 parts by weight of sodium carboxymethylcellulose, 14-22 parts by weight of melamine formaldehyde resin, 3-9 parts by weight of carboxylic butadiene-styrene latex, 4-8 parts by weight of kaolin, 1-3 parts by weight of sodium saccharin, 2-4 parts by weight of magnesium chloride, 7-9 parts by weight of mica, 5-9 parts by weight of bamboo charcoal powder, 2-4 parts by weight of soybean oil, 7-10 parts by weight of aluminum sulfate, 6-8 parts by weight of polyethylene glycol, 2-7 parts by weight of hydroxypropyl methyl cellulose, 3-5 parts by weight of benzotriazole, 3-8 parts by weight of aliphatic acid, 4-9 parts by weight of p-phenylenediamine, 2-6 parts by weight of boric acid and 2-5 parts by weight of honey. The writing duplicating paper has the advantages of smooth writing, tensile resistance and difficult paper jam.

Description

technical field [0001] The invention relates to a writing and copying paper. Background technique [0002] One of the four great inventions in ancient China, papermaking, together with the compass, gunpowder, and printing, provided a material and technological foundation for the prosperity of ancient Chinese culture. The invention of paper ended the complicated history of bamboo slips and slips in ancient times, and greatly promoted the spread and development of culture. Nowadays, paper is indispensable for office work in society, but the existing office paper is generally weak in strength and easy to fold, resulting in unsmooth writing. When printing, it may even cause paper jams, resulting in a lot of resources and time. on waste. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the problem to be solved by the present invention is to provide a copy paper for writing, which is smooth for writing, has a certain degree of tensile resistance,...
