Embodiment Construction

[0025] The present invention will be further described in conjunction with specific embodiments.

[0026] A method for producing wallpaper base paper, comprising the steps of:

[0027] Step A: 30-40 parts by mass of chemically bleached softwood pulp, 10-20 parts by mass of chemically bleached softwood pulp, 10-20 parts by mass of chemically bleached bamboo fiber pulp, 8-15 parts by mass of polyester fiber pulp and 20-30 parts by mass of bleached recycled pulp is mixed into pulp; among them, the degree of knocking of chemically bleached softwood pulp, chemically bleached softwood pulp, and chemically bleached bamboo fiber pulp is controlled between 30-40°SR, and polyester fiber pulp It is obtained by adding water to polyester fibers and beating them through a beater for half an hour to one hour, and the length is controlled between 15 and 35mm.

[0028] Step B: adding 8-15 parts by mass of inorganic fillers and 1-8 parts by mass of chemical additives to the beater to form base...
