Embodiment 1

[0025] The coniferous fully bleached academic pulp, broadleaf fully bleached chemical wood pulp, cotton pulp, and broadleaf BCTMP pulp that are beaten to appropriate beating degrees are prepared into 9000 kg of mixed pulp according to the above weight ratio 10:70:10:10; the beating degree (Beating degree): softwood fully bleached chemical wood pulp 20~30°SR; broadleaf fully bleached chemical wood pulp 20~30°SR; cotton pulp 40~50°SR; broadleaf BCTMP 40~50°SR. Add 800kg of calcium carbonate filler and appropriate AKD, PAE and PAM additives (about 2kg in total) to make paper stock, and the paper stock is dehydrated by fourdrinier wire, pressed, dried and calendered, coiled and finished to obtain 10,000 kg of wallpaper base paper. The online concentration is 0.6%, the pH of the online slurry is 7.5; the calendering conditions: pressure and pressure are applied. The pulp-to-net speed ratio is about 0.99; the basis weight of the prepared wallpaper base paper is 80g / m 3 ; Moisture i...
