Abstract
The invention discloses a processing method of black-core playing card paper, which is characterized in that in the pulping process of base paper, black dyes are added in core pulp, and simultaneously trivalent aluminate is added simultaneously and stirred uniformly. The processing method has the advantage of improving affinity of the black dyes and wood fiber in the core pulp due to adding the black dyes and the trivalent aluminate into the core pulp simultaneously, leading the black dyes in the core pulp not to flow into water in the process of paper making and forming of a paper machine, avoiding a wite section of the paper machine from being polluted and ensuring that only the core layer in the processed playing card paper is black. In addition, the method has simple processing, is suitable for large-batch production and has lower production cost.
Description
Technical field
The present invention relates to the processing method of a kind of cardboard in the paper-making industry, especially relate to a kind of processing method of block-core playing card paper.
Background technology
Playing card receive extensively liking of people as a kind of instrument of entertainment, the Along with people's growth in the living standard, and the sales volume of playing card constantly increases, and the quality requirement of playing card is also improved constantly.At present; High-grade playing card on the market mainly are black core playing card; Its advantage is light tight; Be not easy cheating, and the body paper of present this playing card is bonded with carbon black glue mixing water by two one-side coated papers mainly, its processing technology is complicated, loss is big, cost is high, output is little and mainly rely on import.
Summary of the invention
Technical problem to be solved by this invention provides a kind of processing method of processing simple, with low cost and the block-core playing card paper that can produce in batches.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: a kind of processing method of block-core playing card paper is in the pulping process of body paper, in core slurry, adds black dyes, adds trivalent aluminium salt simultaneously and stirs, and the whole machining process process is:
(1), goes out the required corresponding slurry of surface layer, face lining, sandwich layer, end liner layer and bottom through size degradation, screening, purification, flotation, hot dispersion, bleaching and defibrination Processing of Preparation;
(2), the black dyes that in the mixed stock tank of center stock, adds relative core slurry oven dry stock 1～10%; In this mixed stock tank, add the trivalent aluminium salt and abundant the stirring more than 10 minutes of relative core slurry oven dry stock 1～10% simultaneously, the pH value of this mixed stock tank is controlled between 6.0～7.0;
(3), prepare appear coating layer and the required coating of primary coat layer of cloth through dissolving, mediation, reaction and filtration treatment;
(4), the slurry that will be used to prepare each slurry layer delivers to the moulding of manufacturing paper with pulp of paper machine with approach system, prepares separate surface layer, face lining, sandwich layer, end liner layer and bottom;
(5), be compounded to form cardboard with carrying out press dewatering between each slurry layer; And cardboard carried out dried; The coating that coating prepares on surface layer then forms the face coating layer; The coating that coating prepares on bottom forms the primary coat layer of cloth, at last the cardboard after the coating is carried out surface waterproofing processing, surface treatment, cut paper and choosing reason and produces qualified block-core playing card paper.
Described core slurry is secondary stock or wood pulp.
Described trivalent aluminium salt is the mixture of aluminum sulfate or aluminum sulfate and other trivalent aluminium salt.
Described black dyes is black basic-dyeable fibre or black SULPHUR DYES.
Compared with prior art, advantage of the present invention is owing in the core slurry, added black dyes and trivalent aluminium salt simultaneously, has improved the affinity of xylon in black dyes and the core slurry; Make the black dyes in the core slurry in the paper machine making forming process, can not flow in the water; Avoided web part of paper machine contaminated, guaranteed that it is black that the playing card paper that processes becomes to have only in the paper sandwich layer one deck, and this method processing is simple; Be fit to produce in enormous quantities, production cost is lower.
Description of drawings
Fig. 1 is the vertical section structure sketch map of block-core playing card paper of the present invention.
The specific embodiment
Embodiment describes in further detail the present invention below in conjunction with accompanying drawing.
Embodiment one: a kind of processing method of block-core playing card paper, and its concrete process is following:
(1), going out surface layer 1, face lining 2, sandwich layer 3, end liner layer 4 and bottom 5 required corresponding wood pulp, deinking slurry, secondary stock, deinkings through size degradation, screening, purification, flotation, hot dispersion, bleaching and defibrination Processing of Preparation starches and wood pulp;
(2), in the mixed stock tank of sandwich layer 3 secondary stocks, add the black basic-dyeable fibre of relative secondary stock oven dry stock 5%, in this mixed stock tank, add the aluminum sulfate of relative secondary stock oven dry stock 6% simultaneously and fully stir more than 10 minutes, the pH value that makes this mixed stock tank is 6.7;
(3), through dissolving, mediation, reaction and the filtration treatment preparation required coating of coating layer 10 and primary coat layer of cloth 50 of appearing;
(4), the slurry that will be used to prepare each slurry layer delivers to the moulding of manufacturing paper with pulp of paper machine with approach system, prepares separate surface layer 1, face lining 2, sandwich layer 3, end liner layer 4 and bottom 5;
(5), be compounded to form cardboard with carrying out press dewatering between each slurry layer; And cardboard carried out dried; The coating that coating prepares on surface layer 1 then forms face coating layer 10; The coating that coating prepares on bottom 5 forms the primary coat layer of cloth, at last the cardboard after the coating is carried out surface waterproofing processing, surface treatment, cut paper and choosing reason and produces qualified block-core playing card paper.
The black sandwich layer of processing the block-core playing card paper that obtains through said method is carried out blackness detect, the data result that detection obtains is: whiteness: 39.6, ruddiness :-0.2, blue light :-2.0.
Embodiment two: a kind of processing method of block-core playing card paper, and its concrete process is following:
