Abstract
The invention provides coated paper, which comprises raw paper and coatings formed on two surfaces of the raw paper. Paper pulp for the preparation of the raw paper contains the following slurries of: by weight, 30-80 parts of bleached sulfate hardwood pulp, 0-30 parts of the bleached softwood pulp, 0-30 parts of bleached chemical mechanical pulp and 0-30 parts of alkaline peroxide mechanical pulp. The ash content in the raw paper is 5%-20% by weight. The paint for coating the coating layer contains matt flake china clay. By adjusting the kind and ratio of the raw paper slurries, the ash content of the raw paper to control the roughness and bulkness of the raw paper, the coated paper provided by the invention has an elegant paper color, a concavo-convex feel and a thick loose height. Furthermore, by the addition of matt flake china clay into the paint for coating the coating layer, a high coating seal performance is obtained with fewer coating weight, and the printing effect of the coated paper is good.
Description
Technical field
The present invention relates to a kind of art paper.
Background technology
Art paper is the text paper of processing with body paper coating whitewash, is mainly used in the Commdity advertisement, sample, commodity packaging, trade mark of front cover and the illustration of the senior books and periodicals of printing, colored picture, various finenesses etc.The client has relatively high expectations to art paper, requires the paper look of art paper simple and elegant, and feel is concavo-convex, the height bulky, and seal back mass colour light, and present art paper can't satisfy client's demand.
Summary of the invention
In view of this, be necessary to provide a kind of art paper that effectively addresses the above problem.
A kind of art paper; It comprises body paper and is formed at the coating on body paper two sides; Make the slurry kind that contains in the paper pulp of this body paper and respectively starch the mass fraction of planting and be: the BRATSK of 30-80 part; The bleached sulphate softwood pulp of 0-30 part, bleached chemical wood mechanical pulp of 0-30 part and the APMP of 0-30 part; The quality percentage composition of ash content is 5%-20% in this body paper; Be coated with in the coating of this coating and contain inferior mating plate shape china clay.
Art paper of the present invention is controlled the roughness and the bulk of body paper through kind and the proportioning of the slurry of adjustment body paper, the modes such as content of ashes of body paper, makes the paper look of art paper simple and elegant, and feel is concavo-convex, highly bulky; Add inferior mating plate shape china clay in the coating of this external coating coating, under less coating weight condition, obtain higher coating closed performance, make halftone paper printing respond well.Art paper of the present invention can reach the rerum natura demand of artistic art paper.
The specific embodiment
Art paper of the present invention, it comprises body paper and is formed at the coating on body paper two sides,
The paper pulp that makes this body paper adopts mixed pulp to manufacture paper with pulp and makes; The mass fraction that the slurry kind that contains in this mixed pulp and each slurry are planted is: the BRATSK of 30-80 part (LBKP); The bleached sulphate softwood pulp (NBKP) of 0-30 part, the bleached chemical wood mechanical pulp (BCTMP) of 0-30 part and the APMP (APMP) of 0-30 part.
This LBKP slurry has used Acacia (ACACIA), Eucalyptus, and the tiger slurry waits the slurry kind of high bulk, so that body paper reaches higher bulk.
The slurry of this body paper of manufacturing paper with pulp is added with filler, makes the ash content percentage composition in this body paper be controlled at 5%-20%.The slurry of this body paper of manufacturing paper with pulp adopts the ternary retention system, and (specifically used CATION to keep auxiliary agent, its addition is 0.1-0.3 kilogram/ton paper; Anion keeps auxiliary agent, and its addition is 0.1-0.3 kilogram/ton paper; Weak anionic keeps auxiliary agent, and its addition is 1.0-3.0 kilogram/ton paper), guarantee that total retention rate is 70%-90%, the ash content retention rate is 40%-70%; In addition, add internal sizing agent alkenyl succinic anhydride (ASA) and internal sizing agent alkyl ketene dimer (AKD) simultaneously; The slurry of this body paper of manufacturing paper with pulp also is added with starch, and the addition of starch is 6-12 kilogram/ton paper; For the lower body paper of grammes per square metre (below 80gs m), need to add dry strength agent, so that guarantee suitable tensile strength, guarantee the smooth operation of the section of coating.
The dust point of body paper is 0-5ppm, to satisfy the outward appearance basic demand of high-grade paper.
Crucial rerum natura major control roughness and bulk for body paper.The control of roughness is mainly through the kind and proportioning of regulating slurry and the pressure that reduces paper machine calecder section.The adjusting of bulk mainly be through regulating slurry kind and proportioning, reduce the pressure of the ash content of coal and reduction paper machine calecder section in the body paper.
For roughness, require the dual character basically identical, control two surface roughness relative differences in principle in 10%, the roughness that body paper is every is more excellent to be 5-9 μ m.
For bulk, different body paper grammes per square metres have different requirement, low grammes per square metre (below the 120gsm), and its bulk requires to reach 1.30cm
3More than/g reaches; Higher body paper grammes per square metre (120gsm and more than), its bulk require to reach 1.20cm
3/ g requires paper machine operation personnel that paper machine press polish section pressure is put gently in the control of bulk more than reaching, and bulk can reach higher data like this, so that satisfy the coating requirement of back segment.
Be coated with in the coating of this coating and contain calcium carbonate, inferior mating plate shape china clay, adhesive and coating additive, wherein the mass ratio of calcium carbonate, inferior mating plate shape china clay, adhesive is (40-90): (10-40): (8-14).This coating additive can contain the rheology modification agent, dispersant, and antifoaming agent etc., its each material adds in right amount.The key point of this Design of Coatings Formulation is to add inferior mating plate shape china clay, makes it under less coating weight condition, obtains higher coating closed performance.
Art paper of the present invention requires less coating weight, makes it have concavo-convex feel, and the assurance paper has just been endured property; Require two sided coatings amount basically identical; Control two sided coatings amount relative difference makes the ink absorption on its two sides consistent in 5%, reduces the difference of two sides on printing effect.Said every finishing coat coating weight is 8-20g/m
2, total coating weight is 16-40g/m
2, under the condition that guarantees certain bulk, along with the rising of grammes per square metre, coating weight progressively improves.
Art paper after the coating is without press polish, to guarantee the speciality of bulky.
The rerum natura of art art paper also need satisfy the performance of printing effect, i.e. printing ink retention effect on paper except basic physical properties demands such as bulk; Show as special outstanding of seal back glossiness; The mass colour light, the general seal back glossiness that requires is at least more than 40, owing to used less coating weight; Must use the very high formulation for coating material of coating closure, this is that artistic art paper is different from one of important difference of common art paper.In addition, it is high that the roughness of artistic art paper is wanted, and deflection is excellent, and feel is concavo-convex, and the paper look simple and elegant, be rich in strong art atmosphere, and common art paper do not have this generic request, and this also is that artistic art paper is with respect to the important difference of common art paper another one.
Art paper of the present invention is controlled the roughness and the bulk of body paper through kind and the proportioning of the slurry of adjustment body paper, the modes such as content of ashes of body paper, makes the paper look of art paper simple and elegant, and feel is concavo-convex, highly bulky; Add inferior mating plate shape china clay in the coating of this external coating coating, under less coating weight condition, obtain higher coating closed performance, make halftone paper printing respond well.Art paper of the present invention can reach the rerum natura demand of artistic art paper.
Come the present invention is specified through embodiment below.
