Abstract

The invention relates to a method for producing coating light-weight super-sensitive paper. The super-sensitive base paper is subjected to coating processing; the coating process adopts a 1,760mm coating machine, the speed is 150m/min, the single-sided coating quantity is 15g/m, and the after-coating loose depth is 1.4cm/g; and coatings comprise pigment and a rubber latex adhesive. The pigment is white titanium pigment and porcelain clay specially treated, and the rubber latex adhesive is a mixture of styrene butadiene rubber latex and starch. The surface of the base paper of the invention is not calendered and finished, and the flock paper with natural and native texture is formed on a mesh; on the premise of ensuring the printing effect, the coating light-weight super-sensitive paper produced by the method has the advantages of fewer processing steps, increasing natural and native texture of the paper, high loose depth, strong stereo aesthetic feeling, less reflected light, no dazzling, and soft and comfortable vision. Moreover, the method has the advantages of easy production and low production cost.

Description

technical field [0001] The invention relates to a special paper manufacturing process, in particular to a production method of coated light supersensitive paper. Background technique [0002] We know that papermaking is one of China's four great inventions. Papermaking technology is usually made of fiber raw materials through beating, batching, and papermaking. The performance of paper depends on the type and use of paper. The raw material configuration, The manufacturing method and process technology are different. At present, there are hundreds of varieties of paper, and only packaging paper accounts for 37% of the total packaging materials. Paper has steadily developed from information paper to packaging paper and other industries, varieties, and purposes. As it improves, so does functionality. At present, most of the domestic packaging and decoration papers are made of cardboard or coated cardboard, boxboard, etc., which are of low grade and poor quality, and do not ha...
