Abstract
The invention provides coated paper. The coated paper comprises raw paper and a surface coating formed on the surface of the raw paper; paper pulp for making the raw paper contains the following pulp in part by absolute dry mass: 15 to 30 parts of long fiber pulp, 65 to 85 parts of short fiber pulp, and 0 to 10 parts of mechanical pulp; the pulping freeness of the long fiber pulp is 300 to 400 milliliters, the pulping freeness of the short fiber pulp is 280 to 360 milliliters, and the pulping freeness of the mechanical pulp is 260 to 360 milliliters; and a filler is added into the paper pulp, and the absolute dry mass ratio of the paper pulp to the filler is 100: (6-15). Glue is coated on the surface of the coated paper and can well retain on the surface of the coating and form a membrane, so that the glue is further prevented from permeating to the raw paper, and the coated paper has good box mounting performance.
Description
Technical field
The present invention relates to a kind of coated paper.
Background technology
In the manufacturing process of technique carton, due to the out-of-shape of box, cannot automated production be adopted, box can only be mounted by manual.The glue mounting box is generally PVA acetal glue, and solid content is 6-15%, and viscosity is at more than 1200cps.Mount box paper used except will meeting general hectographic printing and requiring, also will meet the requirement of mounting box, otherwise finished product yield can be brought low, the problem that cost is high.Owing to mounting box glue moisture used up to more than 85%, and paper is mainly made up of fiber, can absorb the moisture content in glue.If paper absorbs the excessive velocities of water in glue, easily occur mounting box loosely, cannot the problem such as re-posted; If it is too slow that paper absorbs moisture content, then printing can be affected.Good mount box performance to ensure that it has, processing producer requires that the gel time of paper is more than 90 seconds.
Summary of the invention
In view of this, be necessary to provide a kind of coated paper effectively solved the problem.
A kind of coated paper, it comprises body paper, is formed at the coating on body paper surface, and containing the fine slurry of length, fluff pulp and mechanical pulp in the paper pulp of this body paper of manufacturing paper with pulp, the absolute dry mass number that wherein each slurry is planted is respectively: long fine slurry 15-30 part, fluff pulp 65-85 part, mechanical pulp 0-10 part; Above-mentioned three kinds of slurries are planted through defibrination process, and wherein the defibrination freedom of long fine slurry is 300-400ml, and the defibrination freedom of fluff pulp is 280-360ml, and the defibrination freedom of mechanical pulp is 260-360ml; Be added with filler in this paper pulp, wherein the absolute dry mass of paper pulp, filler is than being 100:(6-15).
Coated paper of the present invention, by adjusting slurry kind, wet end furnish, stock freeness, the slurry filling content of body paper, thus makes the air permeability of body paper lower than 600ml/min, the gel time of corresponding coated paper 120 seconds and more than.Glue application, in this coated paper surface, can rest on coating surface and film forming preferably, prevents glue further to body paper infiltration, thus has and good mount box performance.
Detailed description of the invention
Coated paper of the present invention, it comprises body paper and is formed at the coating on body paper two sides.
Generally speaking, the coating aperture of coated paper is significantly less than the aperture of body paper: the pore diameter range of body paper is 0.2-10 μm, and the pore diameter range of coating is 0.01-0.2 μm.The compactness of body paper directly affects the absorption of moisture content in its effects on surface coating (coating of general coated paper for printing is all water paints) and adhesive (starch in formulation for coating material, latex etc.), and then affects the absorption of glue.
If the gas permeability of body paper is too high, fast to the moisture absorption in coating, then the adhesive in coating removes moisture content and infiltrates into original paper layer together, thus cause coating porosity good, and then very fast to the absorption of glue.So, glue can not film forming well, cannot mount box smoothly; If now strengthen glue use amount to improve this problem, coated paper can be caused again to absorb water too much and be out of shape, cause mounting box bad.
If the gas permeability of body paper is lower, comparatively slow to the moisture absorption in coating, the adhesive in coating rests on coating surface and film forming preferably, then can stop glue preferably further to body paper infiltration, thus has and good mount box performance.
The air permeability of body paper is by the impact of starching the factors such as kind, wet end furnish, defibrination power, slurry filling (ash).If when the air permeability of body paper controls lower, paper machine dehydration difficulty, thus affect the speed of a motor vehicle of paper machine.In order to promote the running efficiency of paper machine, wish that the air permeability of body paper can control in high bit.But when body paper air permeability is higher, too fast to the moisture absorption of coating, thus affect into the gel time of paper.The air permeability of body paper of the present invention lower than 600ml/min, the gel time (glue is coated on the conjunctiva time on coated paper surface) of corresponding coated paper 120 seconds and more than.
Manufacture paper with pulp this body paper paper pulp in containing long fine slurry, fluff pulp and mechanical pulp, wherein the absolute dry mass number of each slurry kind is respectively: long fine slurry 15-30 part, fluff pulp 65-85 part, mechanical pulp 0-10 part.
Above-mentioned three kinds of slurries are planted through defibrination process, control defibrination freedom by adjustment defibrination power, and wherein the defibrination freedom of long fine slurry is 300-400ml, and the defibrination freedom of fluff pulp is 280-360ml, and the defibrination freedom of mechanical pulp is 260-360ml.
The air permeance resistance of long fine slurry is 40-100s/100ml, and the air permeance resistance of fluff pulp is 10-30s/100ml, and the air permeance resistance of mechanical pulp is 12-35s/100ml.
