本発明は硝子短繊維用バインダー並びに硝子短繊維マツ
、トの製造方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a binder for short glass fibers and a method for producing short glass fibers.
硝子短賓維マットは遠心法、火焔法等によって製造され

、硝子短繊維はバインダーの含む未硬化の固型分によっ
て互に軽く結合され、硝子短繊維マット（生マットと云
う）から形成される。Glass short fiber mats are manufactured by adding a binder to short glass fibers produced by centrifugal method, flame method, etc., depositing them on a moving perforated conveyor to a predetermined thickness, and binding the short glass fibers with a binder. be done.
In the production equipment, the binder is added to the short fibers in a state containing a large amount of water to the short glass fibers, which are kept at a high temperature in a high temperature atmosphere immediately after being produced. Since the binder is heated by the high-temperature atmosphere and short glass fibers, most of the moisture contained in the binder is evaporated, and the short glass fibers are lightly bonded to each other by the uncured solid content of the binder. It is formed from mats (referred to as raw mats).

れるが、熱硬化性樹脂を使用した生マットは可使用時間
の短かく且つ得られた製品に柔軟性がない等の欠点があ
る。The raw mat is sent to the next processing step and used as raw material for various products. For example, by heating a green mat while pressing it between a pair of molds, ceiling panels, heat insulating materials for vehicles, etc. are manufactured. When thermoplastic resin is used as a binder,
If the resulting product is used at high temperatures, it will undergo plastic deformation, so thermosetting resins are exclusively used as binders, but green mats made with thermosetting resins have a short usable life and are advantageous. There are disadvantages such as the lack of flexibility in the manufactured products.
生マットは製造直後連続的に加工工程に送られることも
あるが、包装後、別工場に送られ使用されることも多い
。この場合製造から艮時間経過量ると生マットが劣化し
、劣化性マ、ットを使用すると、強度の充分大きい製品
が得られなくなったシ層間剥離が生じたシする。Raw mats are sometimes sent to continuous processing immediately after production, but are often sent to another factory for use after being packaged. In this case, the green mat deteriorates over time after its manufacture, and if a degradable mat is used, delamination occurs, making it impossible to obtain a product with sufficient strength.
生マットが劣化することなく、充分強度の大きい製品の

用時間の長い生マットの開発が強く要望されているが、
今迄このような生マットは知られていなかった。The elapsed time from the production of the raw mat to the use of the raw mat to obtain a product with sufficient strength without deterioration of the raw mat (
The shelf life of raw mats varies depending on the storage conditions of the raw mats, but it is usually about a few days, so raw mats need to be produced in small quantities according to the amount of use, packed and transported. If the storage period becomes too long due to a malfunction in the processing process, etc., raw mats become unusable, and there is a strong demand for the development of raw mats with a longer usable life.
Until now, such raw mats were unknown.
本発明者はかかる命題を解決する為検討を重ねた結果、
主成分としての熱硬化性樹脂及び副成分としての熱可塑
性樹脂とを水性媒体中に溶解又は分１散せしめてなる′
水性バインダーを使用することにより極めて好適な結果
の得られることを見出し、本発明として提案したもので
ある。As a result of repeated studies to solve this proposition, the present inventor found that
A thermosetting resin as a main component and a thermoplastic resin as a subcomponent are dissolved or dispersed in an aqueous medium.
It has been found that extremely favorable results can be obtained by using an aqueous binder, and the present invention has been proposed.
以下詳述するように、本発明のノ々イングーを使用する
ことにより生マットの可使用時間を大巾に延長すること
ができる。何故このような効果が得られるのか充分明ら
かでないが、およそ次のようなメカニズムによるものと
考えられる。As will be described in detail below, by using the Nono Ingu of the present invention, the usable life of the green mat can be greatly extended. Although it is not fully clear why such an effect is obtained, it is thought that it is due to the following mechanism.
本発明においては熱硬化性樹脂と熱可塑樹脂とを溶解又

ーによって形成された被膜は、熱可塑性樹脂で被覆され
た熱硬化性樹脂微粒によって構成され、このため熱硬化
性樹脂の重合反応が抑制され、可使用時間が大となるも
のと思われる。In the present invention, an aqueous medium in which a thermosetting resin and a thermoplastic resin are dissolved or dispersed is used. These resins have a relatively low degree of polymerization, and when both resins are mixed homogeneously and the binder of the present invention is applied to short glass fibers and the water is evaporated, a film similar to the mixture of both resins is formed. It is formed. Both resins are mixed in extremely small amounts, and the thermoplastic resin is heated to high temperatures and partially melts or softens, so that the film formed by the binder is a thermosetting resin coated with the thermoplastic resin. It is composed of fine resin particles, which is thought to suppress the polymerization reaction of the thermosetting resin and extend the usable life.
本発明のバインダーを使用することにより生マットの可
使用時間を大ならしめる効果が得られる他、さらに生マ
ットを使用して得られた硬化製品は、肌触りも軟かく、
復元性も良好であるという予期せぬ効果を併せ有するこ
とが判明した。By using the binder of the present invention, not only can the usable life of the raw mat be extended, but also the cured product obtained using the raw mat is soft to the touch.
It was found that it also has the unexpected effect of good restorability.
このような効果の得られる理由はおよそ次のように考え
られる。本発明のバインダーを使用して得られた硬化製
品を構成する硝子短繊維の表面は軟かい熱可塑性樹脂で
被覆されているため、硝子短繊維が取扱中、或は加工中
に折損することが少い。このため硬化製品加工中、或は
取扱中に硝子短繊維の折損による短かい切断物が発生し
難い。The reason why such an effect is obtained is considered to be approximately as follows. Since the surface of the short glass fibers constituting the cured product obtained using the binder of the present invention is coated with a soft thermoplastic resin, the short glass fibers are unlikely to break during handling or processing. Few. Therefore, short pieces are less likely to be cut due to breakage of short glass fibers during processing or handling of the cured product.
そして硬化製品中に混在する短かい切断物よ、肌を刺激
する主要原因であシ、本発明のバインダーを使用した場
合、この短かい切断物が非常に少ないので、軟かい肌触
シが得られるものと思われる。Short cut pieces mixed in cured products are a major cause of skin irritation, but when using the binder of the present invention, there are very few short cut pieces, resulting in a soft texture. It seems likely that it will be possible.
又その理由は詳らかでないが、本発明バインダーを使用
して得られた低密度の断熱材を圧縮梱包し、た場合、従
来バイシダーを使用した場合に比し、復元率が向上する
効果も得ることができた。Although the reason is not clear, when the low-density heat insulating material obtained using the binder of the present invention is compressed and packed, the recovery rate is improved compared to when conventional bi-cedar is used. was completed.

加熱することによシ製造される。In the present invention, a thermosetting resin is used as the main component of the binder, and a thermoplastic resin is used as a subcomponent.
A binder obtained by dissolving or dispersing these resins in an aqueous medium is added to short glass fibers immediately after being produced in a short glass fiber manufacturing apparatus.

Moreover, the heat resistance temperature of the obtained product decreases. When the weight ratio is 90 or more, the usable life of the green mat is short, and the obtained product has no flexibility, and the restorability of the product is reduced when it is compressed and packed.

After allowing this raw mat to pass for 5 days, 7 days, and 10 days, Example 1
Glass fiber mats with a thickness of 20% and a density of 48% were produced under the same conditions as above. No delamination was observed in the mats molded after 5 or 7 days, but delamination was observed in the mats molded after 10 days.

A raw mat was produced by applying 10 pieces per mold. Use this raw mat for 5 days, 10 days,
After 20 days, 25 days, and 30 days had elapsed, short glass fiber mats with a thickness of 20% and a density of 48% were produced by pressing and heating for 220,003 minutes using a pair of molds for 5 to 25 days. For the mats that were molded after 30 days had passed, no peeling between the eyebrows was observed.Also, for the mats that were molded after 30 days had passed, slight peeling between the eyebrows was observed, but there was no practical problem.
