Abstract

The invention discloses paper pulp and a high-bulk energy-saving environment-friendly card prepared from the same. The paper pulp is prepared from the following components in percentage by weight: 1 to 10 percent of bleached sulfate softwood pulp, 30 to 70 percent of bleached sulfate hardwood pulp, 20 to 50 percent of chemithermomechanical pulp, and 10 to 30 percent of alkaline peroxide mechanical pulp. The invention also provides the copperplate card prepared from the paper pulp and other components. The paper made with the paper pulp is high in bulk, the gram weight of the paper is effectively controlled to be in a certain range, the paper pulp is prevented from being put into production excessively, and the defibrination energy consumption of a paper machine is reduced correspondingly, so that the effects of environment friendliness and energy saving are effectively achieved.

Description

technical field [0001] The invention relates to papermaking technology, in particular to a paper pulp and a high-bulk energy-saving and environment-friendly copper plate card prepared therefrom. Background technique [0002] Art Board is a high-grade printing cardboard made of base paper coated with white paint, and the weight is above 200gsm (inclusive). It is mainly used for printing the cover of high-grade books and periodicals, color pictures, various exquisite commodity advertisements, samples, commodity packaging, trademarks, etc. Art Board was once translated as art card (literal translation) in my country in the 1930s. Because when this kind of paper was used to print exquisite famous paintings in Europe, the printing plates corroded by copper plates were used for printing. Therefore, according to the convention of naming by purpose, the art paper used for copperplate printing is called copperplate (printing) card. In the printing industry in mainland China, colle...
