Problems solved by technology

Its disadvantages: First, with the expansion of the scale of wood utilization industries such as papermaking, and the reduction of the area of ​​global industrial forests, wood resources for papermaking are gradually scarce, and it is necessary to develop high wood utilization rates, especially the development of inorganic raw materials to replace organic wood fiber raw materials Second, with the needs of social development, papermaking products need to develop new products with safety and anti-counterfeiting functions in addition to the original conventional products to meet the special needs of the society; third, papermaking is a high energy-consuming industry, and among them The beating of papermaking raw materials is the most energy-consuming process in the industrial chain. It is difficult to beating and consumes a lot of energy. The average power consumption per ton of pulp is 300-315kwh. A strategic issue that urgently needs to be resolved

Abstract

The invention relates to a method for preparing enamel paper. Through the addition of cellulase, the preparation method effectively reduces energy consumption of pulping and improves pulp quality; a mineral fiber ingredient is used to replace wood fiber so as to save wood resource and simultaneously reduce production cost; and the prepared enamel paper has anti-counterfeit function.

Description

technical field [0001] The invention relates to a method for preparing coated paper. Background technique [0002] At present, the coated base paper is generally made of wood fiber. Among them, high-grade products, such as coated paper, are made of bleached chemical wood pulp of coniferous wood or hardwood bleached chemical wood pulp; Bleached chemical wood pulp of leaf wood or bleached chemical wood pulp of broad-leaved wood, plus a small amount of semi-chemical thermomechanical pulp, the coated base paper is filled with inorganic pigments, and the ash content of the base paper after burning (ISO1762: 2001) is average 10-20%. Its disadvantages: First, with the expansion of the scale of wood utilization industries such as papermaking, and the reduction of the area of ​​global industrial forests, wood resources for papermaking are gradually scarce, and it is necessary to develop high wood utilization rates, especially the development of inorganic raw materials to replace org...
