Embodiment Construction

[0013] The coated paper provided by the present invention and its manufacturing method will be further described in detail below in conjunction with the accompanying drawings.

[0014] Please also refer to figure 1 and figure 2 , The invention provides a method for manufacturing coated paper and the prepared coated paper. Described coated paper manufacturing method comprises the following steps:

[0015] In the first step, a mixed pulp is provided.

[0016] The mixed pulp includes chemical-mechanical pulp and chemical pulp. The chemical mechanical pulp refers to bleached chemical thermal mechanical pulp (Bleached Chemical Thermal Mechanical Pulp, BCTMP). The chemical pulp refers to pulp obtained by chemically dissociating plant fibers. The mass percentage of the chemical-mechanical pulp in the mixed pulp is 10%-30%, preferably 15%-30%. The mass percentage of the chemical pulp in the mixed pulp is 70%-90%. In this embodiment, the chemical pulp includes bleached broadlea...

Abstract

The invention relates to a coating paper manufacturing method, which comprises the following steps of: providing mixed paper pulp which comprises 10 to 30 mass percent of chemical-mechanical pulp; manufacturing the mixed paper pulp to obtain body paper; and coating surface coating on at least one surface of the body paper to form a surface coating layer, and thus obtaining the coating paper, wherein the surface coating comprises paint; the paint comprises calcium carbonate and porcelain clay; the mass ratio of the calcium carbonate to the porcelain clay is (40-60):(60-40); and the radius-thickness ratio of the porcelain clay is 15 to 40. The invention also provides the coating paper manufactured by adopting the method.

Description

technical field [0001] The invention relates to papermaking technology, in particular to a kind of coated paper with high bulk and its manufacturing method. Background technique [0002] In recent years, the demand for high bulk paper has been increasing. Bulk refers to the volume of paper per unit mass, which determines the air permeability, absorbency, rigidity and strength of paper. The higher the bulk, the lighter the paper is at the same thickness. By increasing the bulk of the paper, the quality of the printed matter can be reduced without changing the number of pages, making it easy to carry and carry. In addition, for paper with high bulk, because of its light weight under the same thickness, it can reduce the use of pulp and reduce the energy consumption of transporting paper, so it has great advantages in saving resources and protecting the environment. There is a particularly strong demand for lightweight paper for books and printing. [0003] One of the metho...
