Description

A kind of enhanced degradable waterproof paper of bismuth hydroxide modifying aramid fiber pulp insulating properties
Technical field
It is enhanced the present invention relates to pulp technology for making paper, more particularly to a kind of bismuth hydroxide modifying aramid fiber pulp insulating properties Degradable waterproof paper.
Background technology
Paper fibre has very strong hydrophily, most of after generally untreated page soaks through water Fibre strength can lose, or even directly crush.In order to meet the development need of people's life requirement and modern industrial technology, paper Application field is increasing.Waterproof paper is widely used in fields such as product packaging, packagings for foodstuff, with the increasingly increasing of environmental consciousness By force, people are more and more stronger for the waterproof paper demand of environment-friendly type degradable.
《The synthesis of high-effect inexpensive wet strength agent and its application in waterproof body paper》Be have studied in one text high-effect low The synthesis technique and its service condition in waterproof body paper of cost polyamides polymeric amine epichlorohydrin wet strength agent PAE resin and into Paper quality, the resin is obvious to the potent fruit of humidification of paper, is a kind of excellent wet strength agent, and the waterproof paper being made of it has good Good wet strength, so that the quality of waterproof paper is improved, water resistance enhancing.Waterproof body paper is mainly by fibre in article Dimension element is prepared, even if the specific additive such as admixture wet strength agent, sizing agent, itself biodegradable is still very It is prominent, under given conditions, by certain hour, waterproof paper still can with degradable, but its waterproof effect have it is certain Limitation, have PP waterproof papers in the market, PP is coated on paper surface using certain special process, there is paper Good water resistance, because PP is petroleum chemicals, its stability is higher, it is difficult to it is biodegradable, harm is caused to environment.This Being accomplished by us coat one layer of good water-proof effect and with can give birth in shaping paper surface while paper applies potent fruit strengthening Thing is degraded the waterproof membrane of effect, the performance of waterproof paper is improved, while the addition difference in functionality type composition before paper shaping, makes to give birth to Thing degraded waterproof paper has other surcharges, improves the market competitiveness.
The content of the invention
The object of the invention is exactly to make up the defect of prior art, there is provided a kind of bismuth hydroxide modifying aramid fiber pulp insulation The degradable waterproof paper of performance enhancement.
The present invention is achieved by the following technical solutions：
The enhanced degradable waterproof paper of a kind of bismuth hydroxide modifying aramid fiber pulp insulating properties, by the raw material system of following weight portion Prepare into：Kp softwood pulp 38-40, hardwood pulp 55-60, PAE resin 1.5-1.6, aluminium polychloride 1.5-1.7, alkane Base ketene dimer 0.2-0.25, distillation appropriate amount of water, WPC 4.2-4.5, beeswax 4-4.5, konjaku glucomannan 1.8-1.9, glycerine 0.1-0.12, Tween 80 0.08-0.09, nylon 11 powder 9-10, bismuth hydroxide 2-3, cation polypropylene Acid amides 2-2.5, Fanglun slurry cake 12-14, diatomite 7-8.
The enhanced degradable waterproof paper of a kind of bismuth hydroxide modifying aramid fiber pulp insulating properties, by walking in detail below Suddenly it is made：
（1）By kp softwood pulp, hardwood pulp mix, add beater in, be subsequently adding PAE resin, aluminium polychloride, Alkyl ketene dimer and appropriate distilled water are beaten, and control pulp density for 3.9-4.2%, beating degree in 38-400SR, Slurry is obtained；
（2）The 10-12 times of distilled water measured will be added in PAMC, dispersed with stirring uniformly adds nylon 11 powder afterwards End, bismuth hydroxide, add Fanglun slurry cake after being stirred 40-60 minutes with 300-400 revs/min of speed, continue to stir 20-30 points Clock, obtains modifying aramid fiber pulp；
（3）Konjaku glucomannan is dissolved in the 10-12 times of distilled water measured, 80-90 DEG C is heated to, will be molten after stirring 30-40 minutes It is stand-by that liquid is cooled to room temperature；WPC is dissolved in the 10-12 times of distilled water measured, stirring to composition dissolving after with it is above-mentioned Solution mixes, and adds glycerine, Tween 80, is heated to 75-80 DEG C, and stirring adds beeswax after 60-80 minutes, under high speed agitator Stirred 50-60 minutes with 1000-1200 revs/min of speed, obtain maceration extract；
（4）By step（2）The product for obtaining is added to step jointly with remaining residual components（1）In the slurry for obtaining, stirring is equal It is dehydrated and squeezing shaping by the wet end in paper machine after even, is then dried by drying chamber and be made paper, then by press polish Hot press extrudes paper, and paper finally is immersed in into step（3）30-40 seconds in the maceration extract for obtaining, at 50-55 DEG C after taking-up Under dry 24-36 hours and obtain final product.
It is an advantage of the invention that：The present invention first compounds PAE resin, alkyl ketene dimer etc., is added to paper pulp In preparation, it is possible to increase the bond strength between paper pulp fiber and fiber, network-like crosslinking knot is formed on fiber interface Structure, the activity between limitation fiber hinders fibrous absorbent swollen, reduction change in size, therefore improves the wet strength of paper, while Compounding composition dispersing and dissolving infiltrates into the surface and inside of fiber in slurry, and polycondensation forms high molecular polymer, further carries The intensity of paper high；It has been modified konjaku glucomannan by the collective effect of WPC and beeswax, maceration extract has been obtained Impregnated by body paper, one layer of degradable film can be formed in paper surface after drying, with good hydrophobic anti- Aqueous energy, while having good mechanical property, tensile strength is excellent with elongation at break, further increases the strong of paper Degree, the product being made is biodegradable, and water resistance is excellent, safety non-toxic.
Present invention addition bismuth hydroxide is added in Fanglun slurry cake, mixes with slurry, improves Fanglun slurry cake with wood pulp Associativity, and the capacitivity for being made paper is enhanced, so as to improve the breakdown voltage value of paper, obtain insulating properties Very big raising；The product excellent insulation performance that the present invention is made, is adapted to routine office work printing, duplicates, and be made of it File is waterproof and dampproof, easily preserves, biodegradable using environmental protection formulae.
