Abstract

The invention discloses a manufacturing method of high-bulk coating printing paper. In the method, high proportion chemical pulp is adopted for coating body paper, light calcium carbonate is used as filler, and high bulk is achieved. A door roller coating machine is used for coating the body paper, and the coating paint adopts plastic paint with a given proportion and a hollow structure, so that the bulk of the coat and the formed paper brightness can be effectively improved. Meanwhile, a soft calender is used for pre-calendering and polishing the coated body paper, so that the fineness of the paper surface is greatly improved while the thickness of the original paper is maintained. The bulk of the high-bulk coating printing paper manufactured through the method is 1.3 to 1.5 cm<3> / g and is far better than that of the ordinary copper paper and light coating paper; and meanwhile, the surface of the paper is smooth and fine, so that printed patterns are full and rich in color, image dots are clear and strong in three-dimensional impression, and the paper is applicable to top-grade color printing.

Description

technical field [0001] The invention relates to a method for manufacturing high-bulk coated printing paper, which belongs to the technical field of papermaking. Background technique [0002] In recent years, the demand for high bulk printing papers has been increasing. The light weight of high-bulk paper not only maintains the thickness and opacity of the original paper, but also can use low-weight high-bulk paper of the same thickness to replace high-weight ordinary double-adhesive paper during printing, which is not only convenient for readers, but also can reduce paper pulp consumption, saving energy and reducing environmental pollution load. [0003] At present, high-bulk printing papers on the market are mainly uncoated light offset papers, and domestic paper companies have not yet developed high-bulk coated printing papers. In order to fill this gap in the market, and from the perspective of saving resources and protecting the environment, China Metallurgical Paper Y...
