Abstract
The invention discloses a method for preparing higher-quality paper from waste compound paper source recycled paper pulp. The higher-quality paper is prepared by the following steps of: preparing waste compound paper source recycled paper pulp or/and sizing agent doped with polyvinyl alcohol fiber into paper; directly impregnating the paper on a paper machine into a colloid addition agent; and drying the mixture on the paper machine by a drying cylinder; or/and adding the colloid addition agent in a waste compound paper source recycled paper pulp blending tank in advance before making paper. The higher-quality paper is characterized by comprising the parameters that the burst index (kPa.m<2>/g) is more than 2.2, the tensile index (N.m/g) is more than 20, the tear index (mN.m<2>/g) is more than 4.0, the Cobb value [(60s)m<2>/g] is less than 30 and the fixed quantity (m<2>/g) is 30-100; and the varieties of the higher-quality paper comprise kraft paper, wrapping paper, non-setting adhesive base paper, glazed paper and base paper for laminating.
