Abstract
The invention provides a buffer paper and a manufacturing process thereof. A size mixture of mercerization wood pulp, softwood pulp and hardwood pulp is used as a fibrous raw material, accessory ingredients such as a wet strength agent/an organic silicon emulsion and an intensifier are added. The method comprises the following manufacturing procedures: feeding materials, pulping, performing pulp grinding, mixing the accessory ingredients, molding on a screen, squeezing, drying, reeling, slitting, and packaging, thereby obtaining the buffer paper. The buffer paper has the advantages of better dry and wet strength, breathability, pressure resistance and high-temperature yellow stain resistance, as well as excellent buffering performance, long service life and the like at high temperature and high pressure, and has better marketability.
Description
Technical field
The present invention relates to a kind of buffering paper and manufacture craft thereof.
Background technology
Buffering paper papery softness, good permeability have shock-absorbing capacity preferably, and available buffer pressure, evenly pressure transmission, reduction alternating temperature speed, uniformly transfer heat are that one of padded coaming commonly used in the circuit board is produced in hot pressing.The shock-absorbing capacity of buffering paper directly influences the quality of hot pressing circuit board.But because the restriction of manufacture craft, material performance etc. cushions paper in the market and still has following problem: moisture is too high or water imbibition is too strong in the buffering paper, and being subjected to after the hot pressing easily, large tracts of land adheres on the substrate; The easily jaundice after the hot pressing of high temperature buffering paper of buffering paper, embrittlement, deformation, the paper resistance to pressure is poor, causes its shock-absorbing capacity to reduce, and circuit board damage, service life shorten.
Along with development of science and technology, people propose requirements at the higher level to the shock-absorbing capacity of buffering paper under the elevated temperature heat pressure condition.And the resistance to pressure of traditional buffering paper, the shock-absorbing capacity under the High Temperature High Pressure are superior inadequately, also have very big room for promotion.
Summary of the invention
The technical problem to be solved in the present invention is, improve at the deficiency on the existing buffering linking technology made of paper, make the buffering paper that resistance to pressure is good, water imbibition is moderate, intensity is high, xanthochromia, deformation are not little under the High Temperature High Pressure of this buffering paper, shock-absorbing capacity is good, more can satisfy market demand.
The technology used in the present invention solution is:
Buffering paper and manufacture craft thereof, it is by the feedstock production of following parts by weight:
160 ~ 180 parts of mercerization wood pulps
240 ~ 260 parts of softwood pulps
75 ~ 85 parts of hardwood pulps
14 ~ 18 parts of wet strength agents
15 ~ 18 parts of organic silicon emulsions
4 ~ 8 parts of reinforcing agents
4 ~ 8 parts in aluminum sulfate
Its manufacture craft flow process is as follows:
Auxiliary agent-go up net forming-squeezing-oven dry-reel-cut-pack feeds intake-pulping-defibrination-sneaks into.
Each raw materials in part by weight is: 170 parts of mercerization wood pulps, 250 parts of softwood pulps, 80 parts of hardwood pulps, 16 parts of wet strength agents, 16 parts of organic silicon emulsions, 6 parts of reinforcing agents, 5 parts in aluminum sulfate.
The active ingredient of described wet strength agent is thermosetting resin, preferred PPE wet strength agent.
Described reinforcing agent active ingredient is modified starch, preferred quaternary ammonium alkyl cationic starch.
Described buffering paper quantitatively be 300 ± 10g/ ㎡, thickness is 0.9 ± 0.05mm, moisture is 8 ± 2%.
With 2% reinforcing agent paper is sprayed before also comprising the laggard drying cylinder of squeezing in the described manufacture craft flow process.
Traditional buffering paper adopts softwood pulp to manufacture paper with pulp mostly, and the softwood pulp fiber is thick, long, and the Unit Weight fiber number is few, and the crosspoint is few, the buffering paper intensity height that makes, but tightness is big, and porosity is low, and gas permeability is poor, and hot buffering effect is restricted; And on the other hand, the aperture of the buffering paper hole that softwood pulp makes is big, and thermal conductivity factor increases, and hot shock-absorbing capacity is influenced.Hardwood pulp fiber finer, weak point, the Unit Weight fiber number is many, and the crosspoint is many, and the buffering paper tightness that makes is little, the porosity height, good permeability, but suction simultaneously and phenomenon of losing water are serious, be subject to influences such as ambient humidity, temperature, its moisture instability, and then influence its shock-absorbing capacity.The mercerising wood pulp has good chemical stability.Therefore, this process adjustments is by adopting the technology of manufacturing paper with pulp jointly of three kinds of wood pulps, makes tightness, porosity, buffering paper that average pore size is moderate, and its dried wet strength, air permeability, water absorbing properties are good, more can satisfy the market demand of hot pressing buffering paper.
Advantage of the present invention and beneficial effect:
1. the buffering paper of selecting for use the mercerization wood pulp of hardwood pulp that the thick long softwood pulp of fiber and fiber finer lack and good stability to manufacture paper with pulp jointly and make has good dried wet strength, gas permeability.
2. the buffering paper that adopts the technology of slurry Inner applying glue and top sizing combination to make has good dried wet strength, resistance to pressure, still can have good shock-absorbing capacity under the High Temperature High Pressure.
3. use organic silicon emulsion as water repellent agent, reduce water absorption rate and the percentage of water loss of buffering paper, stable buffering paper moisture in transportation, storage and use, and has good chemical stability, elasticity, make buffering paper under High Temperature High Pressure, still have intensity, air permeability, resistance to pressure, flexibility preferably, increase its service life.
