Description

A kind of preparation method of the extraordinary thin page base material of plant fiber/glass base
Technical field
The invention belongs to technical field of preparation of specialty paper, are related to a kind of system of extraordinary thin page base material of plant fiber/glass base Preparation Method.
Background technique
The extraordinary thin page base material of plant fiber/glass base is to prepare plant fiber/glass base sound-absorbing and flame-retardant thin sheet material original Material is made of being manufactured paper with pulp by the way of wet papermaking by a certain percentage as plant fiber and glass fibre, to be dipped into gluing It can assign substrate certain intensity after knot agent, easy to produce and use.Plant fiber/thin sheet material of glass base sound-absorbing and flame-retardant is one Kind there are the building decoration materials of sound-absorbing and flame retarding function, it be using the extraordinary thin page base material of plant fiber/glass base as raw material, The maceration extracts such as fire retardant, mill base are impregnated, its good anti-flammability and dicoration is assigned, is used cooperatively with metal piercing ceiling, Acoustic(al)absorbent is collectively constituted, there is good sound absorption.Therefore plant fiber/thin sheet material of glass base sound-absorbing and flame-retardant is applied to Many fields, such as music hall, meeting room, stadium etc..
Since the country at present starts late to the research of plant fiber/glass base sound-absorbing and flame-retardant thin sheet material, although carrying out Some basic research, also make some progress, but there is also many problems during production practices, especially with state Outer product compares, and that there are tightnesses is big for domestic sound-absorbing and flame-retardant product, and bulk is poor, and flexibility is poor, and brittleness is big, and easy moisture absorption etc. lacks Point, high-end plant fiber/thin sheet material of glass base sound-absorbing and flame-retardant rely on imitated and import for a long time.
Summary of the invention
To overcome above-mentioned the deficiencies in the prior art, the object of the present invention is to provide a kind of plant fiber/glass base special type is thin The preparation method of page base material improves the flexibility of substrate, reduces tightness, improves bulk, keeps plant fiber/glass base special type thin Page base material has better paper sense, better absorbent properties.
To achieve the above object, the technical solution adopted by the present invention is that:
A kind of preparation method of the extraordinary thin page base material of plant fiber/glass base, comprising the following steps:
Step 1, the pre-treatment of commercial chemistry pulpboard: taking appropriate pulpboard to impregnate in water after a certain period of time, will with fluffer Fiber is separated into uniform fibrous suspension, and slurry is filtered, wrung out, equilibrium water conten is spare；
Step 2, fiber dispersion: the glass fibre of certain mass and water are placed in fluffer, and dispersing agent is added, discongests After 2w turns, slurry obtained in step 1 is added, then discongests 1w and turns, obtains the mixing slurry of glass and plant fiber；
Step 3, body paper are manufactured paper with pulp: the evenly dispersed mixing slurry of fiber in step 2 being copied in pattern and takes forming of manufacturing paper with pulp on device；
Step 4, maceration extract are prepared: being taken appropriate binder and plasticizer mixing and water adding to dilute to obtain maceration extract, increased in maceration extract Modeling agent mass concentration is 0.25%-1.5%, binder mass concentration is 2%~10%；
Step 5, body paper dipping: the body paper shaped in step 3 being laid flat in the maceration extract of step 4 and is impregnated, and is guaranteed former Paper is flooded completely, dip time 5-120s；
Step 6, it is dry: the l Water Paper page of step 5 being put into drying box and is dried.
Further, the commercial chemistry pulpboard is one of needlebush pulpboard, leaf wood pulpboard or bamboo pulp plate.
Further, in the step 1 commercial chemistry pulpboard soaking time be 4h or more, fiber suspension concentration 6%, The slurry equilibrium water conten time is at least for 24 hours.
Further, manufacture paper with pulp the quantification of 40-45g/m of body paper of forming in the step 32, content of glass fiber 30- 35%, plant fiber content is 65-70%.
Further, 0.005% that dispersant dosage is glass fibre and water quality is added in the step 2.
Further, drying temperature is 130-150 DEG C in the step 6, drying time 4-5min.
Further, the plasticizer includes AFG type plasticizer, AFE type plasticizer or RRJ type plasticizer.
Further, maceration extract is prepared using AFG type plasticizer in the step 4, plasticizer mass concentration is in maceration extract 0.75%, binder mass concentration is 5%；Step 5 dip time is 30s.
Further, maceration extract is prepared using AFE type plasticizer in the step 4, plasticizer mass concentration is in maceration extract 0.5%, binder mass concentration is 6%；Step 5 dip time is 60s.
Further, maceration extract is prepared using RRJ type plasticizer in the step 4, plasticizer mass concentration is in maceration extract 1%, binder mass concentration is 7%；Step 5 dip time is 15s.
The beneficial effects of the present invention are:
Firstly, the present invention by the way that dispersing agent is added when fiber disperses, can make glass fibre evenly dispersed in water, protect Demonstrate,prove the uniform of the extraordinary thin page base material appearance of plant fiber/glass base and performance, avoid fiber dispersion it is uneven caused by under performance Drop；
Secondly, adjusting plant fiber/glass base paper by with different fibrous raw materials are copied and quantifying, guarantee dry in dipping The extraordinary thin page base material of plant fiber/glass base is quantitatively less than 50g/m after dry2；
Finally, impregnating plasticizer to it while body paper impregnates binder, weaken the hydrogen bond knot between plant fiber It closes, weakens the effect combined between fiber, improve the flexibility of substrate, reduce tightness, improve bulk, make plant fiber/glass The tightness of the extraordinary thin page base material of fine base is less than 0.265g/cm3, bulk is greater than 3.77cm3/ g, tensile strength are not less than 13N/ 15mm makes the extraordinary thin page base material of plant fiber/glass base have better paper sense, and better absorbent properties make it easier to receive Glue.The brittleness that material can also be improved simultaneously, is not easily broken it in construction, more adapts to the demand of production and living.
