Description

Paper tube adhesive and production method thereof
Technical field
The invention belongs to tamanori technical field, be specifically related to paper tube adhesive and production method thereof.
Background technology
Paper tube (paper tuber) sticks with glue agent and is commonly called as paper tube adhesive, paper web glue etc., is a kind of special-purpose adhesive making various paper tube, fiber drum, paper can and relevant paper product.The deformable sheet materials such as paper, cloth, plastic film, tinsel, conventional paper web (paper tube) reels bundled, makes paper tube core web-like finished product.These paper webs are generally roll with kraft paper or other raw material paper machinery, be bonded, and tamanori used is called paper web glue.
Along with the fast development of China's economy, paper tube is increasing in the requirement in daily necessities, weaving, light industry, packaging, leather etc. field.As reel package paper tubes such as toiler roll inner core paper web, weaving spool, cloth, paper product, leather, plastics film etc.Paper tube (cylinder) glue that tradition is commonly used mainly contains gelatin, pasted starch (comprising Sumstar 190 and treated starch), polyvinyl formal liquid (107) tackiness agent, polyvinyl acetate emulsion (white glue with vinyl), PVA solution etc.Wherein gelatin, starch adhesive because bonding strength is low, staging life shortly do not use substantially; The maximum shortcoming of polyvinyl alcohol adhesive is exactly poor water resistance, and paper tube compressive strength increases with the shelf-time and significantly declines, and improves, but still can not meet the demands although can obtain part after acetalation; The water tolerance of polyvinyl acetate emulsion is all better than front several tackiness agent, but the compressive strength of low, the bonding rear paper tube of initial bonding strength and creep resistance difference are its main drawbacks.The paper tube adhesive of development of new meets the demand in market.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of initial bonding strength good, just the sticky time is short, and bonding strength is high, mobility and excellent storage stability, bonds without the paper tube adhesive of the premium propertiess such as warpage, the invention still further relates to the production method of this paper tube adhesive.
The production method of paper tube adhesive of the present invention, comprises the steps:
1) get the raw materials ready: the starting material preparing following weight part: vinyl-acetic ester 32-38 part, mangrove bark 8-10 part, polyvinyl alcohol 7-9 part, ethylene glycol 2-3 part, polyacrylamide 0.5-1.5 part, dibutyl phthalate 0.5-1.5 part, emulsifying agent 0.5-1.5 part, Potassium Persulphate 0.5 part, pure water 110-130 part;
2) to the process of mangrove bark:
1. autoclaving: by mangrove bark chopping or after pulverizing, put into pressure pan, be forced into 20-30MPa, make its pressure uniform, and keep 10-20min, recover normal pressure;
2. steam explosion: steam explosion tank put into by material step 1. obtained, burstpressures 3.0-3.5Mpa, the dwell time maintains 150-200s;
3. decoct, decolour: material step 1. obtained the heavy pure water such as to add and decocts 2 times, each 1 hour, obtains extracting solution, filters, united extraction liquid, filtrate is concentrated into the medicinal extract that relative density is 1.30 (surveying when 70 DEG C); Add activated carbon decolorizing in medicinal extract, filter;
3) add a small amount of water in retort, be warming up to 60 DEG C, stir 0.5h, then add polyvinyl alcohol, polyacrylamide, emulsifying agent and purified water remainder;
4) continue to be warming up to 90-95 DEG C, keep until polyvinyl alcohol all dissolves;
5) be cooled to 69-71 DEG C, filter, add 3/4 Potassium Persulphate, and slowly drip vinyl-acetic ester;
6) temperature 69-71 DEG C is kept, reaction 6-7h;
7) temperature is risen to 85-90 DEG C, add remaining 1/4 Potassium Persulphate, reaction 0.5-1h;
8) be cooled to 75 DEG C, add step 2) the mangrove bark filtrate that obtains, reaction 1-2h;
9) be cooled to 55 DEG C, add dibutyl phthalate and ethylene glycol, stir 0.5h, be cooled to room temperature, filtration, discharging.
Step 1 of the present invention) described in get the raw materials ready, the starting material of preferred following weight part: vinyl-acetic ester 35 parts, mangrove bark 10 parts, polyvinyl alcohol 8 parts, ethylene glycol 2.5 parts, polyacrylamide 1 part, dibutyl phthalate 1 part, emulsifying agent 1 part, Potassium Persulphate 0.5 part, pure water 120 parts; The preferred fresh mango skin of described mangrove bark.
Step 2) described in the preferred 3-5% of activated carbon dosage (w/v).
Step 5) described in add Potassium Persulphate, preferably a small amount of repeatedly, described slow dropping vinyl-acetic ester, preferably at least drips 1h.
The invention still further relates to the paper tube adhesive adopting aforementioned production method to obtain, is the even thickness glue of oyster white.
Compared to existing technology, the invention has the advantages that:
1, the paper tube adhesive that the present invention obtains is the product of the novel high-performance be made up of high molecular polymer, has initial bonding strength good, and just the sticky time is short, and bonding strength is high, mobility and excellent storage stability, and bonding is without premium propertiess such as warpages.Currently available products is generally 3-4 month storage period, product chambers of the present invention is gentle put more than 6 months not stratified, never degenerate.
2, the present invention does not use the material such as W-Gum and thickening material, but adds the performance that mangrove bark improves product.The fiber of mangrove bark have good thickening effectiveness, but the fiber in mangrove bark vegetable cell is bondd by lignin, not easy fracture, product can be caused to lump, precipitation, the present invention adopts steam explosion, under high temperature, high pressure steam effect, cellulose crystallity improves, and the polymerization degree declines, and hemicellulose fraction is degraded, lignin softens, horizontal strength of connection declines, even softening plastic, when being full of the material sudden pressure reduction of pressure steam, gas play in hole is expanded, produce " explosion " effect, partly can peel off lignin, and raw material is torn as fiber fines.By such process, the Mierocrystalline cellulose in mangrove bark can be utilized well.Add plant constituent in product, meet environmental protection, natural theory.
3, the paper tube adhesive that the present invention obtains is applicable to various high, medium and low all kinds of paper tube machinery production and application, also can be used for fiber drum and produces, replace the paper tube such as white glue with vinyl, polyvinyl alcohol bonding glue.The paper tube intensity made is high, stiffness good, not embrittlement, and the paper tube using the present invention adhesion-molded increases by 35%, more than 45% than prior art respectively in hardness, intensity.Meanwhile, glued membrane moisture resistivity is good, improves more than 35% compared to existing technology, can meet the requirement of various paper tube moisture resistivity completely.Can not only significantly improve hardness and the intensity of paper tube, can greatly reduce costs again, be a kind of novel low-cost, the high-performance paper tube adhesive that replace traditional paper tube adhesive.
