Abstract
The invention discloses a preparation method for ultra-fine glass fiber chopped strands in the papermaking industry. The ultra-fine glass fiber chopped strands are prepared by chopping glass fiber into be stands in 4-25 micrometers, and putting the stands into a water solution according to the mass ratio of 1:(0.05-20) for sufficient dispersing for 0.5 to 30 minutes through ultrasonic dispersion equipment. Since the glass fiber is a brittle material, and elongation at break is small, the flexibility is relatively low or the brittleness is relatively high. Therefore, how to well disperse the ultra-fine glass fiber chopped strands and avoid harms on the ultra-fine glass fiber is a technological difficulty, the ultrasonic dispersion technology is adopted for efficiently dispersing the ultra-fine glass fiber chopped strands, the dispersing effect is good, and the original properties of the glass fiber cannot be impacted. The ultra-fine glass fiber chopped strands with high dispersing performance, provided by the invention, can be used in the papermaking industry and for paper making, and paper made by using the method is high in tensile strength and has improved folding strength, while the tearing index is basically unchanged.
Description
Technical field
The present invention relates to the preparation field of glass fibre, more particularly to a kind of ultra-fine fibre glass for paper industry
The preparation method of chopped strand.
Background technology
In paper industry, the range of choice of extraordinary paper material is very extensive, and wherein glass fibre is as inorganic
The Typical Representative of non-metallic fibers, because its tool is different from the property of string and other synthetic fibers, is gradually subject to
The extensive concern of paper industry, becomes the new raw material of Development and Production special paper products.And in the last few years, with national economic development
With social progress, no matter in industrial production or daily life, people are to the species of new material and the demand of function also not
Disconnected expansion.Glass fibre is one of Inorganic Non-metallic Materials new function material and structural material, and its main component is two
Silica, contains the oxide of other big materials many, such as calcium, boron, sodium, magnesium, aluminium etc. simultaneously.Common glass fibre appearance is in
Transparent and smooth is cylindric, and its section is in complete circle, diameter typically from several microns to twenties meters micron,
Every bundle fiber precursor is made up of hundreds of even thousands of monofilament. because glass fibre is fragile material, extension at break very little,
Therefore its flexibility is less or fragility is larger, therefore all-glass paper only needs to aborning disperse and can not use common beating process
Processed, it is individual for therefore how carry out good dispersion not hurting thin glass fiber by ultra-fine fibre glass chopped strand again
Technological difficulties.
Ultrasonic wave dispersion refers to liquid as medium, by ultrasonic wave " cavitation " effect in a liquid, by liquid
Particle carries out disperseing the process with de-agglomerated.Ultrasonic technology, as a kind of physical means and instrument, can produce each in a liquid
Plant extreme condition, this phenomenon is referred to as phonochemistry effect, related ultrasonic device is then referred to as the (letter of ultrasonic acoustic chemical device
Claim " phonochemistry equipment ").Ultrasonic wave dispersing apparatus are a kind of applications of phonochemistry equipment, can be used for water process, the dispersion of solid-liquid system,
The de-agglomerated of particle, promotion solid-liquid reaction and other effects in liquid.
Content of the invention
The purpose of the present invention is to overcome deficiency of the prior art, provides a kind of ultra-fine fibre glass for paper industry
The preparation method of chopped strand, ultra-fine fibre glass chopped strand is carried out good dispersion and does not hurt thin glass again by the method
Fiber, is effectively disperseed to ultra-fine fibre glass chopped strand using ultrasonic dispersion technique, and dispersion effect is good and does not affect
The original performance of glass fibre, can be used for paper industry ultra-fine fibre glass chopped strand produce the tensile strength of paper,
Folding strength increases, and tear index is kept essentially constant.
For solving above-mentioned technical problem, the present invention provides a kind of ultra-fine fibre glass chopped strand for paper industry
Preparation method, using glass fibre through being chopped into 4～25 microns of precursor, is 1:0.05～20 according to mass ratio, is placed at water
Fully dispersed and prepared through dispersion 0.5-30min in ultrasonic wave dispersing apparatus in solution.
Preferably, described glass fibre is alkali-free glass fibre or medium-alkali glass fibre and high-strength glass is fine
Dimension.
As another preferably, the ultrasonic wave dispersing apparatus frequency range of described employing: 15khz～60khz, conventional frequency:
20kh, every unit nominal power is 1500w, 2000w or 3000w, or said units are applied in combination.
Compared with prior art advantages of the present invention is as follows: because glass fibre is fragile material, extension at break very little, therefore
Its flexibility is less or fragility is larger, and therefore all-glass paper can not be processed with common beating process aborning, therefore
How carry out good dispersion not hurting thin glass fiber by ultra-fine fibre glass chopped strand is a technological difficulties again, this
Bright using ultrasonic dispersion technique, ultra-fine fibre glass chopped strand is effectively disperseed, dispersion effect is good and does not affect glass
The original performance of fiber.Can be used for the ultra-fine fibre glass chopped strand of paper industry using the high dispersive performance of present invention preparation
The tensile strength of paper producing, folding strength increase, and tear index is kept essentially constant.
Specific embodiment
Embodiment 1
Glass fabric adopts the g75 Weave type electronic-grade glass yarn that Chongqing Polycomp International Corporation produces (single
Fibre diameter be 9um, line density be 68.7tex) for raw material be cut into 4.5mm about be chopped move precursor, juxtaposition is in aqueous；
It is ultrasonic wave dispersing apparatus using the single groove ultrasonic cleaning machine tm1012 that Wuxi Environmental Protection Technology Co., Ltd produces,
It is 28khz using ultrasonic frequency, disperses 20 minutes, thus be obtained that there is the ultra-fine glass that high dispersive performance can be used for paper industry
Glass fiber chopped strand.
Because glass fibre is fragile material, extension at break very little, therefore its flexibility is less or fragility is larger, therefore glass fibers
Dimension paper can not be processed with common beating process aborning, therefore how to carry out ultra-fine fibre glass chopped strand good
It is a technological difficulties that good dispersion does not hurt thin glass fiber again, and the present invention adopts ultrasonic dispersion technique fine to superfine glass
Dimension chopped strand is effectively disperseed, and dispersion effect is good and does not affect the original performance of glass fibre.Using present invention preparation
High dispersive performance can be used for the tensile strength of paper of ultra-fine fibre glass chopped strand production of paper industry, folding strength
Improve, and tear index is kept essentially constant.
