Description
Technical field
The present invention relates to a kind of preparation method of waterleaf paper for velcanized fiber, belong to pulp technology for making paper.
Background technology
Vulcan fibre is one of most important speciality paper of China, and flintiness is very high, claims vulcanized fiber paper (indurated paper), hard steel cardboard again.The vulcan fibre papery is hard, has excellent elasticity, ABRASION RESISTANCE, corrosion resistance, heat resistance, mechanical strength, insulating properties and machining moulding performance, very easily is suitable for various machinings, like cutting, boring, sticking folded, punching out and grinding etc.It is that to adopt slaine-liquor zinci chloridi that cellulose is had violent swollen and a gel characteristic be finishing agent, to the steel body paper handle, range upon range of making.
Vulcan fibre production procedure at present mainly contains batch (-type) vulcan fibre production line and serialization vulcan fibre production line.In the vulcanized fiber board production technology that batch (-type) and continous mode are produced, there is following defective:
(1) be prone to moisture absorption and deformation, vulcan fibre is in the higher environment of humidity, and meeting flexural deformation loses original planarization;
(2) rough surface, moist one-tenth degree is not enough;
(3) be prone to fade, fade, waterleaf paper for velcanized fiber uses organic direct dyes, and washing, light fastness is not ideal enough.
In order to improve the performance of vulcan fibre, solve the shortcoming that present vulcan fibre exists qualitatively, must adjustment raw material---steel body paper inherent quality.Because the particularity that vulcan fibre is produced, require to contain in the steel body paper alkali matter, resin, metal fillings and other and chip and impurity the zinc chloride reaction.Therefore, only use a spot of organic direct dyes to paint in the production process of steel body paper at present, can't use any filler, and the high pollution of organic dyestuff price is serious.
Summary of the invention
The technical problem that the present invention will solve provides a kind of preparation method of waterleaf paper for velcanized fiber, uses the vulcan fibre surface of body paper preparation of the present invention to be fine and close oxidized metal fibrage, and the vulcan fibre surface is moist; Do not fade; No color differnece, water imbibition is low, and is difficult for getting damp; Weatherability, heat resistance and light fastness all improve a lot, and the tightness of vulcan fibre, tensile strength and planarization are greatly improved.
For solving the problems of the technologies described above, the technical scheme that the present invention taked is: a kind of preparation method of waterleaf paper for velcanized fiber, comprise the preparation of top layer waterleaf paper for velcanized fiber and the preparation of interlayer waterleaf paper for velcanized fiber, and the preparation of top layer waterleaf paper for velcanized fiber may further comprise the steps:
(1) pulping: utilize hydrabrusher that the cotton pulp dregs of rice are carried out pulping and handle, institute's water is a running water;
(2) making beating: the slurry that step (1) the is obtained processing of pulling an oar;
(3) slurry that step (2) is obtained imports joins in the stock tank, and evenly adds inorganic pigment;
(4) slurry that step (3) is obtained imports and adds running water in the mixing pit and dilute;
(5) import in the header box after the slurry screening that step (4) is obtained and the removal of impurities, adding retention agent continuously in header box obtains top layer waterleaf paper for velcanized fiber paper pulp;
(6) copy paper, make the top layer waterleaf paper for velcanized fiber, and store the plain boiled water of this generating step.
The preparation of interlayer waterleaf paper for velcanized fiber may further comprise the steps:
(1) pulping: utilize hydrabrusher that the cotton pulp dregs of rice are carried out pulping and handle, institute's water is a plain boiled water;
(2) making beating: the slurry that step (1) the is obtained processing of pulling an oar;
(3) slurry that step (2) is obtained imports and adds plain boiled water in the mixing pit and dilute;
(4) copy paper, make the interlayer waterleaf paper for velcanized fiber.
The addition of inorganic pigment is 2～7.5% of an over dry stock quality in the step (3).
During preparation melanic epipedon waterleaf paper for velcanized fiber, inorganic pigment is the compound of iron oxide black and iron oxide green, and the mass ratio of iron oxide black and iron oxide green is 10:3.
When preparing green top layer waterleaf paper for velcanized fiber, inorganic pigment is the compound of iron oxide green and iron oxide black, and the mass ratio of iron oxide green and iron oxide black is 58:15.
When preparing white top layer waterleaf paper for velcanized fiber, inorganic pigment is a titanium dioxide.
When preparing brick-red waterleaf paper for velcanized fiber, inorganic pigment is an iron oxide red.
During preparation large red waterleaf paper for velcanized fiber, in joining stock tank, evenly add the iron oxide red of over dry stock quality 2%, and in joining stock tank, evenly add direct fast scarlet, directly the addition of fast scarlet is 1 of over dry stock quality～2 ‰.
Retention agent is the PAMC aqueous solution in the step (5), and the mass concentration of the PAMC aqueous solution is 2 ‰.
The addition of PAMC is 2/10000ths to 5/10000ths of an over dry stock quality.
Plain boiled water: plain boiled water contains inorganic pigment for the top layer waterleaf paper for velcanized fiber prepares the water that produces in the step in the process (6).
Retention: become the pigment content of paper and the ratio of the amount of pigment of adding.
Over dry slurry: the slurry that refers to dewatered drying to constant weight.
Adopt the beneficial effect that technique scheme produced to be: during the waterleaf paper for velcanized fiber of production of the present invention top layer, use inorganic pigment, the inorganic pigment light resistance is stronger; Covering power is better, and strong coloring force can play good colouring effect; And inorganic pigment has played the effect of filler again in waterleaf paper for velcanized fiber; Make body paper fine and smooth more, the present invention has reduced production cost, has reduced environmental pollution.
Use the vulcan fibre surface of body paper preparation of the present invention to be fine and close oxidized metal fibrage; The vulcan fibre surface is moist, does not fade no color differnece; Water imbibition is low; And be difficult for getting damp, weatherability, heat resistance and light fastness all improve a lot, and the tightness of vulcan fibre, tensile strength and planarization are greatly improved.
The white fibre body paper whiteness that the inventive method makes can reach more than 95 degree; The disposable retention of iron oxide red is 80～85% when preparing brick-red waterleaf paper for velcanized fiber, and the final retention of iron oxide red can reach more than 95%.
The plain boiled water that produces in the preparation process of overlay paper directly is used in the preparation process of lining paper, can make waste water reuse, reduces the pollution to environment, and can improve the retention of inorganic pigment again.
