Abstract
The invention discloses a production method for high-bulk packing board, which is characterized in that during preparing the pulp required by linings and cores, mechanical pulp is added into the waste paper pulp for preparing the linings and the cores during pulp mixing, and the binder formed by mixing starch and reinforcing agent is added to the mesh part of a paper machine during compounding the paper pulp layers, so as to compound the paperboard. The invention has the advantages that compared with the white cardboard processed through traditional method, the high-bulk packing board, (mainly the white cardboard) processed through the method has high bulk, (namely less quantitative property under the same thickness or high thickness under the same quantitative property), high interlayer strength, high printing applicability and excellent deflection, reduces the fiber consumption, reduces the consumption of the wood, and facilitates the protection of the environment and resources.
Description
Technical field
The present invention relates to the production method of cardboard in the paper-making industry, relate in particular to a kind of production method of high bulk packing board.
Background technology
Along with The development in society and economy, the demand of paper and manufactured goods thereof is increasing, but the forest reserves are limited, the finiteness of forest tree resource and demand growing particularly thorny.Along with the fast development of China's paper industry, the increasing rapidly of paper total output, the supply problem of paper making raw material resource becomes the biggest problem of puzzlement China paper industry development.
At present, product external packagings a lot of on the market all adopt carton package, and art post paperboard is a kind of packing board of large usage quantity owing to strong abundant, the quantitatively big packing that is widely used in product.But because the Quantitative Comparison of art post paperboard is big, cause the amount ratio of slurry such as in the production process of art post paperboard paper pulp bigger, the consumption of its corresponding fibre resources is also bigger, is unfavorable for the protection of environment and resource.And if simple reduction is quantitative, can cause the indexs such as thickness and deflection of art post paperboard to descend, do not meet instructions for use.
Summary of the invention
Technical problem to be solved by this invention provides a kind of under the prerequisite that guarantees properties of product, the production method of the high bulk packing board that its Quantitative Comparison is little in the same thickness.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: a kind of production method of high bulk packing board, and concrete production process is:
(1), prepares the required slurry of surface layer, lining, sandwich layer and bottom respectively through size degradation, screening, purification, flotation, hot dispersion, bleaching and defibrination;
(2), with the slurry of lining and sandwich layer when mixed stock tank mixes slurry, add bulk>=2.0m toward the secondary stock that is used for preparing lining and sandwich layer respectively
3The mechanical pulp of/g; And mix and form the required mixed pulp of each layer; Wherein in the mixed pulp of lining: the weight percentage of mechanical pulp is 30～70%, the weight percentage of chemical pulp and secondary stock is 30～70%, and in the mixed pulp of sandwich layer: the weight percentage of mechanical pulp is 35～80%, the weight percentage of chemical pulp and secondary stock is 20～65%;
(3), prepare qualified coating through dissolving, blending, reaction and filtration treatment;
(4), the slurry that will be used to prepare each pulp layer delivers to the moulding of manufacturing paper with pulp of paper machine with approach system, prepares surface layer, lining, sandwich layer and bottom respectively;
(5), each pulp layer is carried out compound tense; After the wet end of paper machine adds by the starch binding agent that mixing forms with reinforcing agent, is combined into cardboard, to cardboard squeeze, dried; WATER REPELLENT TREATMENT is carried out on the surface of facings and bottom respectively then; On surface layer and bottom, coat the coating for preparing again respectively and form face coating layer and primary coat layer of cloth, at last cardboard is carried out press polish, cut paper and choosing reason, produce qualified high bulk packing board.
When the described mixed slurry of step (2); Toward the described mechanical pulp of secondary stock interpolation that is used for preparing bottom; And mix and form the required mixed pulp of bottom, wherein in the mixed pulp of bottom: the weight percentage of mechanical pulp is 15～30%, the weight percentage of chemical pulp and secondary stock is 70～85%.
Described reinforcing agent is a polyacrylamide.
Compared with prior art; Advantage of the present invention is to compare with the art post paperboard that conventional method processing obtains through the high bulk packing board (mainly referring to art post paperboard) that this method processing obtains; Its bulk high (promptly thickness is high under quantitative little identical in other words quantitative conditions under the same thickness condition), and interlaminar strength is high, printing adaptability is high, deflection good, and fiber consumption is few; Reduced consumption, helped the protection of environment and resource timber.
