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, also known as vulcanized fiber paper (indurated paper), hard-steel cardboard.Vulcan fibre papery is hard, has the shaping performance of excellent elasticity, ABRASION RESISTANCE, corrosion resistance, heat resistance, mechanical strength, insulating properties and machining, is very easily suitable for various machining, as cut, boring, sticky folded, punching and grinding etc.It adopts the slaine-liquor zinci chloridi having violent swollen and a gelation properties to cellulose to be finishing agent, processes, stacked obtained to steel body paper.
Current vulcan fibre production procedure 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 defect:
(1) easy 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 inadequate;
(3) easily 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, solving the shortcoming that current vulcan fibre exists qualitatively, must raw material be adjusted---steel body paper inherent quality.Due to the particularity that vulcan fibre is produced, require can not to contain in steel body paper alkali matter, resin, metal fillings and other the chip reacted with zinc chloride and impurity.Therefore, only use a small amount of organic direct dyes to paint in the production process of current steel body paper, any filler cannot be used, and the high pollution of organic dyestuff price is serious.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of preparation method of waterleaf paper for velcanized fiber, the vulcan fibre surface using body paper of the present invention to prepare is dense oxide metallic fibrous layer, vulcan fibre surface is moist, do not fade, no color differnece, water imbibition is low, and not easily gets damp, weatherability, heat resistance and light fastness all improve a lot, and the tightness of vulcan fibre, tensile strength and planarization are greatly improved.

(4) copy paper, obtained interlayer waterleaf paper for velcanized fiber.
In step (3), the addition of inorganic pigment is 2 ~ 7.5% of over dry stock quality.
When preparing 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 coat waterleaf paper for velcanized fiber, inorganic pigment is titanium dioxide.
When preparing brick-red waterleaf paper for velcanized fiber, inorganic pigment is iron oxide red.
During preparation large red waterleaf paper for velcanized fiber, in pond with slurry, evenly add the iron oxide red of over dry stock quality 2%, and evenly add Photooxidative Degradation of Direct Fast Scarlet in pond with slurry, the addition of Photooxidative Degradation of Direct Fast Scarlet is 1 ~ 2 ‰ of over dry stock quality.
In step (5), retention agent is the cationic polyacrylamide aqueous solution, and the mass concentration of the cationic polyacrylamide aqueous solution is 2 ‰.
The addition of cationic polyacrylamide is 5/20000 to ten thousand/10000ths of over dry stock quality.
Plain boiled water: plain boiled water is the water produced in step (6) in the waterleaf paper for velcanized fiber preparation process of top layer, containing inorganic pigment.
Retention: become the pigment content of paper and the ratio of the amount of pigment added.
Over dry slurry: refer to the slurry of dewatered drying to constant weight.
The beneficial effect adopting technique scheme to produce is: during production top layer waterleaf paper for velcanized fiber of the present invention, use inorganic pigment, inorganic pigment light resistance is stronger, covering power is better, and strong coloring force, can play good colouring effect, and inorganic pigment serves again the effect of filler in waterleaf paper for velcanized fiber, make body paper finer and smoother, present invention reduces production cost, decrease environmental pollution.
