Embodiment 1
[0020] A method for preparing matte coated paper, comprising the following steps:
[0021] (1) Base paper preparation: Mix coniferous wood pulp and reed pulp at a mass ratio of 1:10 to obtain a mixed pulp, add 5% starch by mass and 8% calcium sulfate by mass to the mixed pulp, and perform PFI grinding and beating , and then carry out papermaking and drying to obtain base paper;
[0022] (2) Preparation of coating: the coating is made of the following components in parts by weight: sizing material 70, starch 12, dispersant 1, flake zinc powder 3, flake sericite powder 3, spherical calcium carbonate 1; The mass ratio of flaky zinc powder, flaky sericite powder, and spherical calcium carbonate is 3:3:1;
[0023] (3) Coating: The coating prepared in step (2) is coated with a double-sided film coater, dried with hot air after coating, and then finished with a four-roll double-sided soft-tight calender , that is.
[0024] Further, the number of beating revolutions of the PFI mill...
