The content of the invention
It is an object of the invention to provide a kind of industrial wiping paper high with physical property intensity and preparation method thereof.
To reach above-mentioned purpose, present invention employs following technical proposal：A kind of industrial wiping paper of the present invention, the work
The slurry of industry cleansing tissue is made by not floating straw pulp and not floating bamboo pulp, wherein the quantification of 15g/m of the wrapping paper2-20g/m2, make
Paper wet strength agent content is the 1.0%-2.5% of the oven dry stock, and auxiliary agent content is the 0.3%-1.25% of the oven dry stock.
Further, the brightness of the industrial wiping paper is 20-50%ISO, and tensile index is 32-47Nm/g, tear
Index is 15-20mNm2/ g, burst index is 1.2-2.0KPam2/ g, folding strength is 80-100 times.
Further, the slurry is made up of the following component of percentage by weight：
Straw pulp 30%-50% is not floated,
Bamboo pulp 50%-70% is not floated.
The preparation method of industrial wiping paper of the present invention, comprises the following steps：
(1) self-control is not floated straw pulp and does not float bamboo pulp and mixed in stock tank, make slurry uniform；
(2) slurry after mixing passes sequentially through stock tank, low dense fiberizer, straw pulp after decker, concentration and starches tower after kowtowing,
Slurry after being beaten；
(3) wet strength agent for papermaking is added in stock tank into paper machine stock tank to slurry obtained by step (2), makes to be well mixed；
(4) into slurry obtained by step (3), addition auxiliary agent enters header box, makes to be well mixed；
(5) by slurry obtained by step (4) on paper machine successively through fan pump, wet end, blanket portion press section, drying section, coil paper
Machine and high-speed cutter post-processing, are made industrial wiping paper.
Further, in step (2), mashing is beaten in low dense fiberizer, and defibrination rotating speed is 10000-
20000r/min, beating consistency is less than 10%；Beating degree is 20-40 ° of SR, and weight in wet base is 7-10g, and water retention value is 110-150%.
Further, in step (5), the slurry from header box flow into wet end when online concentration be 0.1-1.0%,
Wet end is 50-200 mesh.
Further, in step (3), described wet strength agent is water-soluble cationic thermosetting resin, described water-soluble
Property cation thermosetting resin be polyamide polyamine epoxy nitrogen propane PPE, polyamide epoxy atmosphere propane PAE or oligomeric through polyimide resin
At least one of PHA.In working practice, it is found that the wet strengthening effect of PPE and PAE resin is better than PHA resins, but PHA trees
Fat it is cheap, and commercial resin concentration is high compared with first two, therefore increase PHA resin demands can also reach PPE and PAE intensity
Effect, and cost is also lower.
Further, in step (4), the auxiliary agent is methylpropene sodium sulfonate, is a kind of white as paper making intensifier
Color crystalline powder, it is soluble in water, ethanol and dimethyl sulfoxide are slightly soluble in, insoluble in other organic solvents.
Further, in step (5), the rotating speed of the paper machine is 200-400m/min.
Beneficial effect：Safety and environmental protection of the present invention, dry and wet intensity is high, and tear index and folding strength are higher, and physical property is strong
Degree is high.
Compared with prior art, the invention has the advantages that：
(1) cell membrane of wheat straw fiber is relatively thin, is easily broken under the mechanism of mashing, wire-dividing broom purification and fibrillating
Comparatively fast, adhesion is higher between fiber, and adhesion close relation is all higher into paper tensile index and burst index between fiber, but
Be due to wheat straw fiber (straw pulp) average length it is shorter, the tear index and folding strength into paper are very low；Bamboo pulp fiber (bamboo
Slurry) average length it is longer, the tear index and folding strength into paper are higher.
(2) will not float straw pulp and do not float bamboo pulp by a certain percentage be well mixed after be beaten so that bamboo pulp fiber passing through
Wire-dividing broom purification evenly after mashing is crossed, microfibre is isolated, then paper making additive is added, the slurry finally obtained
Drainage capacity is greatly increased, the reduction of the beating degree of slurry, when beating degree is relatively low, its into paper every physical index compared with bamboo pulp
It is high.
(3) wet strength agent water-soluble cationic thermosetting resin, is added in paper pulp, because resin positive charge with negatively charged
Hydroxyl and cellulosic hydroxy that the adsorption reaction of the fiber of lotus and wet strength agent contain form the combination of hydrogen bond, adsorb fiber surface
Substantial amounts of wet strengthening resin.When paper page drying position, influenceed by dryer temperature, intermolecular hydrogen bonding dehydration.Polycondensation occurs for resin simultaneously
Effect, now resin be changed into the state for being not used in water, it is and interface-cross-linked into can not be entirely water destruct in string
Resin network structure, therefore swollen of the fiber not by water is protected, make paper that there is wet strength, while also assigning the dry strength of paper.
(4) because of low weight paper after wetting, how many pairs of the combination ratio of the self-strength of fiber and single fiber intertwined point
Less, intensity now is mainly reflected in the collective effect effect of wet strength agent and auxiliary agent, while because of wet strength agent for the influence of wet strength
Polycondensation and auxiliary agent attract, the retention of wet strengthening resin and auxiliary agent is improved, thus the dry and wet intensity of page improve,
This is one of the reason for auxiliary agent improves intensity.The two of reason are after auxiliary agent and wet strengthening resin adapted, the flocculation phenomenon of slurry compared with
To be obvious, the drainage rate of slurry is faster than the drainage rate that non-adding assistant is starched, therefore auxiliary agent has retention filtrating aid function with wet strength agent to slurry,
Because being kept to fiber fines, and fiber fines are adsorbed with substantial amounts of wet strengthening resin, so also just improving wet strengthening resin
Retention.
