Copper plate card and preparation method thereof

Abstract

The invention provides a copper plate card, which comprises base paper, a ground coating and a surface coating, wherein the ground coating and the surface coating are coated on both sides of base paper in sequence; the preparation raw material for base paper comprises chemical pulp, mechanical pulp, wet-end chemicals, an inner sizing agent and a surface sizing agent, and the chemical pulp accounts for 20 to 80 parts by weight, and the mechanical pulp accounts for 10 to 30 parts by weight; the ground coating comprises pigment accounting for 60 to 100 parts by weight and an adhesive accounting for 10 to 17 parts by weight; and the surface coating comprises pigment accounting for 70 to 100 parts by weight and an adhesive accounting for 8 to 15 parts by weight. The invention also provides a preparation method of the copper plate card. The copper plate card and the preparation method select and use the mechanical pulp in a suitable proportion, reduce the utilization of the chemical pulp, save natural resources such as forest, water and the like, are beneficial to environmental protection, and ensure the quality; in addition, the bulk of the energy-saving environment-friendly copper plate card with high hard fold quality is controlled within 0.95 to 1.05cm<3> / g, the folding endurance of obtained paper is good, the coating quantity on the both sides are concordant approximately, the remaining effect of printing ink on the paper surface is excellent, and the color of ink is bright.

Description

technical field

[0001] The invention belongs to the field of pulp mixture, in particular to a copper plate card and a preparation method thereof. Background technique

[0002] With the rapid development of the times, ordinary paper on the market has become more and more difficult to meet the requirements of many customers at home and abroad. Customers hope to have personalized requirements, and they all hope to have higher pursuit of quality to meet specific demand. For high-quality copperplate cards, it is necessary to increase the paper folding strength to a higher level, and the production materials are more energy-saving and environmentally friendly, fully meeting the quality requirements of post-processing. Therefore, in order to meet the needs of this part of customers in the market, we have specially developed copperplate cards with high folding resistance, quality, energy saving and environmental protection.
