[Industrial Field of Application] The present invention relates to a method for manufacturing glass paper using a neutral papermaking method using ultrafine glass fiber as the main raw material. After 50 parts of glass fiber and polyvinyl alcohol binder were disintegrated with water under neutral conditions at a concentration of 0.5 to 2.0% for 5 to 10 minutes, 1 to 1 of polyethylene glycol alkyl phenyl ether type nonionic surfactant was added.
The present invention relates to a glass paper production method characterized by adding a 20 ppm concentration solution, dispersing it at a concentration of 0.01 to 0.1%, and making paper with a basis weight of 50 to 100 g/m 2 . Glass fibers include ultrafine glass fibers with an average fiber diameter of 0.2 to 2.6 μm and fiber lengths of 5 mm to 2.5 μm.
There is chopped strand glass fiber with a fiber diameter of 6 μm to 20 μm. Among these, glass paper manufactured using the wet papermaking method (water-based papermaking method) using ultrafine glass fibers as the main raw material is used for applications such as high-performance air filters or battery separators, heat insulation materials, and sound-absorbing materials.

When producing glass paper using the wet papermaking method using ultra-fine glass fibers, glass has a hydrophobic surface, so its dispersion in water is significantly lower than that of hydrophilic pulp fibers. It has been difficult to produce glass paper with good texture and suitable for practical use using papermaking methods. Therefore, in the past, “INDUSTRIAL AND

As can be seen in "Pulp Symposium Abstracts", pages 9-19 (1984), glass paper was manufactured by a wet papermaking method using sulfuric acid acidic water (pH 3.2 or less). However, the method of manufacturing glass paper using acidic sulfuric acid has problems in terms of work safety and corrosiveness of the equipment, so the present invention was arrived at as a result of intensive research into wet papermaking methods using neutral conditions. .

When manufacturing ultrafine glass fibers using the wet papermaking method,
The concept of disaggregation → dispersion → paper making is important. Ultrafine glass fibers are flocculent, and in order to produce glass paper using the wet papermaking method, the first important point is how effectively to disintegrate the fibers. In other words, if the ultrafine glass fibers are insufficiently disintegrated and undisintegrated fiber bundles remain, even if they are dispersed and made into paper using the conventional sulfuric acid water solution, the formation of the glass paper will be good and it will not be suitable for practical use. cannot be manufactured. Therefore, we investigated how to effectively disintegrate these ultrafine glass fibers. That is, as an ultra-fine glass fiber, the product name Manville 106 (0.54~0.68μ
mφ) (manufactured by Manville) and 20 g of water in TAPPI
Put it in a disintegrator (manufactured by Kumagai Riki Kogyo Co., Ltd.) and disintegrate it for a predetermined period of time.
After diluting the sample with water to give a % concentration, it was collected in a 500 ml graduated cylinder and visually judged (Table 1). Furthermore, chopped strand glass fiber (6mm,
The disintegration state when 2 g of Manville 106 (0.54 to 0.68 μm φ) was mixed with 20 g of Mannville 106 (0.54 to 0.68 μm φ) and disintegrated in the same manner is also shown. For comparison, Table 1 shows the results of a similar disintegration treatment using sulfuric acid acid water (PH2.5) instead of water.

を中性にて行なうことの可能性を鋭意検討した。[Table] As a result, the same state of disintegration can be obtained in a shorter time when disintegrated in neutral conditions than in the conventional acidic sulfuric acid solution, and the disintegration speed can be further accelerated by adding chopped strand glass fibers. It turned out that. The preferred amount of chopped strand glass fibers is 10 to 50 parts per 100 parts of ultrafine glass fibers. If it is less than 10 parts, it will take a long time to disintegrate, and if the
If it exceeds 50%, the ratio of ultrafine glass fibers decreases, which increases the gap and decreases the collection rate of fine particles, which is not preferable. The next step is dispersion and paper making.Glass fibers inherently have extremely poor dispersion in water, so even if ultra-fine glass fibers are separated into individual fibers by effective disintegration, they will quickly aggregate in neutral water. Conventionally, sulfuric acid water was used for dispersion and paper making. However, the use of sulfuric acid acid water poses problems in terms of operational safety and corrosiveness of the equipment, so the possibility of performing dispersion and paper making in neutral conditions was investigated.

も何等支障はない。[Means and effects for solving the problem] As a result, if a polyvinyl alcohol binder is added during disintegration of glass fibers, and then an aqueous solution of a polyethylene glycol alkyl phenyl ether type nonionic surfactant is used during dispersion, It has been found that it is possible to produce glass paper similar to dispersion and paper making using sulfuric acid water. As a polyethylene glycol alkyl phenyl ether type nonionic surfactant,
Types using octyl groups, nonyl groups, etc. as alkyl groups can be used. The concentration of the aqueous solution used is 1 to 20 ppm, preferably 5 to 10 ppm. If the concentration of the aqueous solution is less than 1 ppm, the dispersion ability will be weak and it will not be possible to produce glass paper with good formation that is suitable for practical use. On the other hand, even if the concentration is higher than 20 ppm, a significant improvement in the dispersion effect cannot be obtained, which is uneconomical and undesirable. It has also been found that when glass paper for air filters, for example, is produced with neutrality, the filter performance is improved compared to when it is produced with acidic sulfuric acid. This is presumed to be because glass fibers are less damaged when glass paper is manufactured using neutrality. In the present invention, it is necessary to use a polyvinyl alcohol binder to ensure the strength of the glass paper, but it is also necessary to use a water repellent or an inorganic filler such as talc or TiO 2 to ensure water repellency. There is no problem in using it as an internal addition or impregnation.

(0.54-0.68μmφ) (manufactured by Manville) 10g, trade name Manville 108A (0.69-1.1μmφ) (manufactured by Manville) 4g, chopped strand glass fiber (6mm, 9μmφ) (manufactured by Asahi Fiberglass) 6

After adding and disintegrating for 7 minutes, the specified concentration (1.0
Add a polyethylene glycol nonyl phenyl ether type nonionic surfactant aqueous solution 8 of the trade name Neugen EA160 (manufactured by Dai-ichi Kogyo Seiyaku Co., Ltd.) adjusted to ~20 ppm), and add the inversion type of trade name SV-538A (manufactured by Shimazaki Manufacturing Co., Ltd.). The mixture was stirred in an agitator for 5 minutes. The basis weight of the glass paper used to obtain this liquid is approximately 75g/m 2
Add the Neugen EA160 aqueous solution that was collected and adjusted to the specified concentration as described above to bring the total volume to 4,
After stirring for another 3 minutes in an inverted agitator, a self-made round JIS type hand paper machine (wire mesh area 0.0191 m 2 , wire mesh opening)
Glass paper was made using 75mesh). In addition to this wet paper, the product name is Dijitsu EY (manufactured by Goo Kagaku Co., Ltd.).
After water-repellent treatment using a wax emulsion-based water repellent, glass paper for air filters was produced by drying with a cylinder dryer, and the formation was visually determined. The performance of this glass paper was evaluated using a self-manufactured flat sheet filter testing device. Comparative Example 1 used an aqueous solution of polyethylene glycol nonyl phenyl ether type nonionic surfactant (trade name: Neugen EA160) whose concentration was adjusted to 0.5 ppm. Example 6 As a surfactant, trade name Nitsusan Nonion

The results are shown in Table 2, and the formation of the glass paper for air filters wet-made in neutral conditions was not changed at all compared to the conventional glass paper produced in sulfuric acid conditions. In addition, the main performance of an air filter is expressed by the DOP smoke (dioctyl phthalate, particle size 0.3 μm) collection rate and pressure loss, and the desirable air filter performance is to meet a certain standard of DOP smoke collection rate as low as possible. This is achieved through pressure loss, but glass paper for air filters manufactured in neutral condition
HEPA filter standard, i.e. 0.3μm particle size.
Although the DOP smoke collection rate of 99.97% or higher is fully satisfied, the glass paper for air filters manufactured with acidity was below this standard.
