Embodiment Construction
[0017] A preparation method of tipping paper base paper, comprising the following steps:
[0018] (1) The coniferous wood pulp and the hardwood pulp are beaten and mixed evenly to obtain tipping pulp, and the weight ratio of the softwood pulp to the hardwood pulp is 1:0.8;
[0019] (2) Mix calcium carbonate, nano-titanium dioxide, and sodium hydroxide solution at a weight ratio of 1:0.5:10, then put them into a closed high-pressure reactor, and keep warm at 120°C for 24 hours. After cooling and filtering, use the obtained solid Washing with distilled water, and then drying at 100°C for 10 hours to obtain tipping paper filler;
[0020] (3) Add the tipping paper filler, sizing agent and retention aid described in step (2) successively to the tipping paper slurry described in step (1) and mix evenly, and then after forming, drying and calendering The tipping paper base paper is obtained after the treatment, and the weight ratio of the tipping paper slurry, the tipping paper fill...
