Description
Technical field
The present invention relates to a kind of adhesive tape body paper, it is brown that this paper has higher dried wet physical strength, color, is suitable for producing adhesive tape.The invention still further relates to the production method of this adhesive tape body paper, especially utilize pin, wealthy wood fiber raw material, adopt the technology of DDS low energy consumption displacement cooking, oxygen delignification, hydrogen peroxide bleaching explained hereafter adhesive tape body paper.
Background technology
Need use a kind of adhesive tape to be used for blocking or are bonding in industries such as automobile, house fitting-up, packing.Adhesive tape in the market mainly contains plastic adhesive tape and paper substrate adhesive tape, and the page of producing the paper substrate adhesive tape requires to have certain physical intensity, water repelling property, ageing-resistant performance, with the ordinary production in the guarantee adhesive tape processing process and the product quality of adhesive tape.Produce satisfactory adhesive tape body paper, generally need to use full needlebush sulfate wood pulp, production cost height.
The applicant applied for the patent of invention of title " method for producing Chinese red pine chemical pulp ", and application number is 200710035263.6, and the applying date is on June 26th, 2007, and this patent application document has been introduced a kind of masson pine DDS displacement cooking method.
The applicant also applied for the patent of invention of title " a kind of production of stretched paper bag ", and application number is 2007100349737, and the applying date is on May 17th, 2007, and this patent application document has been introduced a kind of production of stretched paper bag.
The production method that Chinese patent application CN200410093808.5 discloses a kind of shrunk adhesive tape rough paper on May 11st, 2005 adopts 100% bleaching needlebush kp softwood pulp, pull an oar through sticking shape mode, the pulping beating degree is 45 ° of SR～55 ° SR, wet strength agent for papermaking puts in the pulp storage tank, pulping carries out wet strength agent for papermaking to be handled, last paper machine is copied paper, wet crepe, dry, batch, and make wet strong crepe paper, the interior apparatus for coating of the machine of introducing subsequently carries out permeability-reducing admixture glue coating processed, dry, finished product, batch and make shrunk adhesive tape rough paper, its surface has significantly fine and closely woven, irregular wrinkle lines effect, percentage elongation is 10%-15%, wet strength is about 20-30%, and have good barrier performance, satisfied the instructions for use of wrinkle adhesive tape product.Yet the disclosed adhesive tape base paper production method of this patent application document all uses softwood pulp, the production cost height; The PAE-LT wet strengthening agent causes the production cost height up to 5-10% (to oven dry stock, wet strengthening agent is by 100%), and the broken that produces in the process of manufacturing paper with pulp is high-leveled and difficult to handle because of wet strength, has limited the use of this production method; Adopt sticking shape mode to pull an oar, the beating degree height not only causes energy consumption higher, also influences the performance of product.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of have low energy consumption, low pollution, paper physical intensity height on the aforementioned techniques basis, can utilize broad-leaved wood fiber raw material and wood machining residues raw pulp, help the cleaning pulping paper method of comprehensive utilization of resources, the adhesive tape body paper that obtains with its production method has the wet strength than the high level cadre, be difficult for broken end in body paper dipping, the coating process, the adhesive tape quality of producing is better, satisfies instructions for use.
In order to solve the problems of the technologies described above, the invention provides the raw materials for production and the production technology of adhesive tape body paper are improved, the product of production reaches following technical indicator: fracture length 〉=6.0km, tensile strength 〉=1.5kN/m, moisture content 7%～10%, tightness 〉=0.62g/cm
3, wet strength 〉=0.33kN/m, whiteness 17%～25%.
In order to obtain the former paper product of above-mentioned adhesive tape, production method of the present invention comprises following content: wood fiber raw material, adopt the low energy consumption displacement cooking, sieve is washed in sealing, oxonium base delignification, the little wood pulp that floats of hydrogen peroxide bleaching explained hereafter, float the disposed slurry whiteness at 19%～27% (ISO), paper with 100% primary wood pulp through joining slurry, be to pull an oar under 2.5%～4.5% the condition at slurry concentration, beating degree is 26～32 ° of SR, weight in wet base is 10.5～15g, and the making beating disposed slurry is through desanding, condiment, fine screen, wet end dehydration moulding, squeezing, preceding dry, the back is dry, batch, packing forms the adhesive tape body paper.
Improvement project one as aforementioned production method, in basic production method, wood fiber raw material is the masson pine of using 50～60 weight portions, the leaf wood of 20～30 weight portions, the China fir side plate and/or the glued board industrial wood waste of 15～25 weight portions when producing the adhesive tape body paper.
As the improvement project two of above-mentioned production decision, in basic production method, in the condiment process, add paper weight percentage when producing the adhesive tape body paper and be 1%～8% PEA wet strength agent.
As the improvement project three of above-mentioned production decision, in basic production method, when producing the adhesive tape body paper, page compresses through stretching property device in dry run, can further improve the physical strength of page, improve the longitudinal stretching rate especially after, the paper tensile property is improved.
The wet strength agent of the present patent application is preferably polyamine epichlorohydrin resin (be called for short PAE resin), belongs to water-soluble, CATION, thermosetting resin, solid content: 12.5 ± 0.5%.Wet strength agent for papermaking such as also spendable Lauxite, melmac and polyamine.
Aforementioned adhesive tape body paper quantitatively, tensile strength, fracture length, paper whiteness, tightness, wet strength, all by pulping and paper-making industry concerned countries, portion or industry standard detection, be known technology.
Beneficial effect of the present invention is:
Since adopt low energy consumption displacement cooking, sealing wash sieve, oxonium base delignification, hydrogen peroxide bleaching, in dense technology, reduced the energy consumption in the pulping process, (AOX) reaches the purpose of cleaner production with the generation of dioxin noxious material to have reduced discharged waste water and organohalogen compounds; Because of adopting the cold boiling technology that spurts of DDS, oxonium base delignification, hydrogen peroxide bleaching are produced little wood pulp that floats, the Kappa number and the paper pulp yield of slurry have been improved, reduced in the production process damage to fiber, improved the intensity of chemical pulp, adopt specific beating process and page is vertically compressed processing with stretching property device, improved the physical strength of paper, under the prerequisite that keeps product high strength to require, can reduce beating degree, energy efficient improves the absorbent properties of paper following process, thereby improves the product quality of adhesive tape; Can mix the leaf wood paper pulp of more staple fibres, can enlarge the use amount of broadleaf on the one hand, make the wood fiber raw material source secure, on the other hand,, can improve the absorbent properties of adhesive tape body paper, improve product quality by adding leaf wood paper pulp; Especially can utilize relatively poor wood machining residues of wood fibre and small dimension wood raw material, can economize on resources, reduce production costs,, enlarge the scope of application of paper by improving the intensity of page.
