Description

High temperature hot-pressing type bedding paper and production method thereof
Technical field the present invention relates to a kind of industrial paper and production method thereof, especially a kind of high temperature hot-pressing type bedding paper and production method thereof that is used for the electronic circuit board manufacturing.
Background technology is used for electronics industry printed wire board manufacturing process, needs a kind of course in its hot pressing, to guarantee the normal manufacturing and the product quality of wiring board.In recent years, along with manufacturing develop rapidly of electronic circuit board and electronic circuit board continuous advancement in technology, the material that uses in the wiring board process from the consumption and qualitative demand more and more higher.Because of paper has surface of good flatness, air permeability, cleanliness factor, certain buffer capacity and resistance to elevated temperatures, the characteristic of low cost and reusable edible is subjected to the attention of electronic circuit board processing enterprise day by day.Because the paper as course has the special performances requirement, the at present domestic manufacturer that does not still have maturation, produce as the high temperature hot-pressing type bedding paper in the wiring board manufacture process, each wiring board manufacturer is mainly with varnish(ed) paper replacement high temperature hot-pressing type bedding paper or from external import high temperature hot-pressing type bedding paper, the former exists paper performance can not satisfy the quality requirement of wiring board course fully, access times are few, and the cost height influences the quality of wiring board; The latter exists price higher, and shortcomings such as paper source complexity, quality index are uneven, supply of material protection difference also directly influence the stable and production cost of wiring board quality.
Summary of the invention the object of the present invention is to provide and a kind ofly uses domestic raw material cheap and easy to get and every physical and chemical index reaches or near the high temperature hot-pressing type bedding paper and the production method thereof of external similar advanced product.
The present invention is achieved in that
1, adopting raw material is the sulfate wood pulp manufacturing of masson pine, China fir, leaf wood.Described leaf wood can be leaf woods such as maple, alder, gray gum.The proportioning of various raw materials in paper is: masson pine 50-65 weight portion, China fir 10-20 weight portion, leaf wood 20-35 weight portion.Perhaps the percentage by weight of each raw material can be: masson pine 50-65%, China fir 10-20%, leaf wood 20-35%, gross weight is 100%.
2, manufacture paper with pulp after mixing making beating with sulfate masson pine wood pulp, sulfate China fir slurry, sulfate hardwood pulp, its process conditions are as follows:
(1) slurry Kappa number: 28-32;
(2) slurry beating degree: 19-22 ° SR;
(3) online process conditions: (A) online concentration: 0.3-0.5%; (B) online pH value: 6.5-8.5;
(4) squeezing process condition: one presses: 2.0kgf/cm 2Two press: 2.2kgf/cm 2Three press: 2.4kgf/cm 2
(5) soft calendaring process conditions: nip pressure 1.5-3Kg/cm; Calendering temperature 80-120 ℃; Page moisture content 6-8% before the entrance pressure light.
The high temperature hot-pressing type bedding paper of Sheng Chaning quantitatively is 150-260g/m as stated above 2, moisture is 5-8%, tightness is 0.6-0.65, air permeability 〉=8um/Pa*s, water absorbent surface amount (Cobb) value 〉=250g/m 2, suction head 〉=28mm/10min, water soluble chloride content≤150mg/kg, water soluble sulfate content≤150mg/kg, water extract pH value 6.5-8.5.Can reach or the approaching QUALITY STANDARD of like product abroad.
Specific embodiment embodiments of the invention one: with masson pine wood chip, China fir wood chip, leaf wood wood chip, by 13 tons of 52: 20: 28 weight proportion modulation, after the Extended Delignification boiling, produce Kappa number and be 31.8 slurry, after washing, screening.Paper stock through making beating, net part forming, unipress, stage drying, soft calendaring ornamenting, batch, high temperature hot-pressing type bedding paper 6400kg that rewinding obtains the customer requirements specification.Production technology: beating degree 19-22 ° SR, the online concentration 0.4% of manufacturing paper with pulp; Squeezing: one presses 2.0Kgf/cm 2, two press 2.2Kgf/cm 2, three press 2.4Kgf/cm 2Soft calendaring technology: nip pressure 1.5-3Kgf/cm 2, 7% one-tenths paper roll water intaking of moisture content minute 6.8% before the calendering temperature 80-120 ℃, entrance pressure light; The high temperature hot-pressing type bedding paper product feature that makes: quantitatively be 158g/m 2, moisture is 6.8%, tightness 0.62g/cm 3, air permeability 12.5um/Pa*s, water absorbent surface amount (Cobb) value 308g/m 2, suction head 29mm/10min, water soluble chloride content 63mg/kg, water soluble sulfate content 96mg/kg, water extract pH value 8.3.
In order to make the recycle of papermaking resource energy, production method of the present invention can be equipped with new wood pulp with the useless high temperature hot-pressing type bedding paper after using and manufacture paper with pulp jointly, useless high temperature hot-pressing type bedding paper generally is not more than 20% with the weight ratio of new wood pulp, but the ratio of new each raw material of wood pulp in becoming paper is with all identical with new wood pulp.
Embodiments of the invention two: with masson pine wood chip, China fir wood chip, leaf wood wood chip, by 13 tons of 55: 18: 27 weight proportion modulation, after the Extended Delignification boiling, produce Kappa number and be 30.6 paper pulp, after washing, screening, the useless high temperature hot-pressing type bedding paper of processing after using with the via line plate is mixed with paper stock for 1.2 tons.Paper stock through making beating, net part forming, unipress, stage drying, soft calendaring ornamenting, batch, high temperature hot-pressing type bedding paper 7500kg that rewinding obtains the customer requirements specification.
Production technology: beating degree 19-22 ° SR, the online concentration 0.4% of manufacturing paper with pulp; Squeezing: one presses 2.0Kgf/cm 2, two press 2.2Kgf/cm 2, three press 2.4Kgf/cm 2Soft calendaring technology: nip pressure 1.5-3Kgf/cm 2, moisture content 6.9% before the calendering temperature 80-120 ℃, entrance pressure light, become the paper roll water intaking to divide 6.8%; The high temperature hot-pressing type bedding paper product feature that makes: quantitatively be 158g/m 2, moisture is 6.8%, tightness 0.63g/cm 3, air permeability 12.8um/Pa*s, water absorbent surface amount (Cobb) value 306g/m 2, suction head 28mm/10min, water soluble chloride content 75mg/kg, water soluble sulfate content 92mg/kg, water extract pH value 8.2.Because production process is used the delignified sulfate wood pulp of the degree of depth; Adopt advanced top net former assistant formation, through the soft press-polishing machine surfacing, good product quality, especially paper surface flatness, air permeability, cleanliness factor and resistance to elevated temperatures index satisfy the requirement that wiring board is produced, belong to domestic initiation, heat transfer property is good, and elasticity is big, and access times reach 3-6 time.I have mended domestic blank by the high temperature hot-pressing type bedding paper wad of company's exploitation, to domestic industry technical paper market important influence.
Masson pine among the present invention, China fir, leaf wood are domestic timber varieties of trees commonly used, fast growth, and resource is plentiful, and it is domestic that raw material of the present invention can be based on, cheap and easy to get.
The invention has the beneficial effects as follows: raw material sources are based on our country, and production cost is lower, use in processing In the journey, the wiring board steady quality can all be recycled after the use, can effectively reduce in the wiring board production process Cost. To promoting process for cleanly preparing, protection of the environment, developing a circular economy, improve product specification and have Important meaning.
