Abstract

The invention discloses a formula and a production method of high-bulk color card paper. The formula comprises, by mass, 30-40% of needle leaves, 60-70% of broad leaves, 50-60% of pattern card waste paper, 40-50% of mechanical pulp, 1.2-2.0% of starch, 2.0-8.0% of a dye, 0.1-0.15% of a retention aid, 1.0-1.5% of AKD, 1.0-2.0% of spray starch, 1.0-3.0% of a leavening agent, surface gelatin and a surface reinforcing agent. The production method specifically comprises the following steps: 1, preparation of a surface pulp; 2, preparation of a core pulp: mechanical pulp treatment, pattern card waste paper treatment and mixing treatment; and 3, papermaking treatment. The color card paper has the advantage of high folding resistance, high bulk, high paper surface flatness, high color stability and high texture.

Description

technical field [0001] The invention relates to the technical field of color cardboard and its preparation process, in particular to a high-bulk color cardboard formulation and a preparation method thereof. Background technique [0002] Color cardboard is a design style that designers and printers are constantly seeking to make their works stand out. Many times color cardboard can make them icing on the cake. This kind of high-quality paper product is soft to the touch, gorgeous in appearance, and the finished product is more noble and pleasing to the eye. There are many kinds of color cardboard, each with its own characteristics, and its grade is higher than that of ordinary paper. It mainly produces high-end packaging boxes, cards, handbags, greeting cards, etc. [0003] The current color cardboard still has the problems of unsatisfactory folding endurance, paper bulk, paper surface flatness, color stability and texture. Contents of the invention [0004] The object o...
