Description

本発明はガラス繊維チョプドストランドマット等のガラス繊維製マットなど、ガラス繊維不織布の製造に利用されるポリエステル樹脂組成物及びこれを用いたガラス繊維製マットに関する。 The present invention relates to a polyester resin composition used for producing a glass fiber nonwoven fabric, such as a glass fiber mat such as a glass fiber chopped strand mat, and a glass fiber mat using the same.

従来ガラス繊維製マットの結合剤で固体粉末の商品として、ビスフェノールＡにエチレンオキサイドを付加したものにフマール酸を反応させた化合物、イソフタール酸とフマール酸とグリコールを反応させたエステル等があった。しかし固体粉末は親水度が高く、１００ｇ／ｍ２、２００ｇ／ｍ２のガラスマットの生産には固体粉末が流れ落ち、無駄が多く、又そうでないものは固体粉末の軟化点が低く貯蔵中に塊状となってブロッキング現象を起こしたりしていた。 Conventionally, as a product of solid powder with a binder of a glass fiber mat, there are a compound obtained by reacting fumaric acid with bisphenol A added with ethylene oxide, an ester obtained by reacting isophthalic acid, fumaric acid and glycol. However, the solid powder has high hydrophilicity, and the production of glass mats of 100 g / m 2 and 200 g / m 2 has a lot of waste and the waste of the solid powder. Otherwise, the solid powder has a low softening point and becomes a lump during storage. Blocking phenomenon.

本発明は上述のガラス繊維チョプドストランドマット等のガラス繊維製不織布の製造に使用できる結合剤である。ガラス繊維製マット等を製造する場合にガラス繊維の交点に効率的に付着するガラス繊維結合剤組成物及びこれを用いて形成されたガラス繊維製マットを提供することを目的とする。 This invention is a binder which can be used for manufacture of nonwoven fabrics made from glass fibers, such as the above-mentioned glass fiber chopped strand mat. An object of the present invention is to provide a glass fiber binder composition that efficiently adheres to the intersection of glass fibers when producing a glass fiber mat or the like, and a glass fiber mat formed using the same.

本発明は上記目的を達成するため鋭意検討した結果、芳香族酸（テレフタル酸、イソフタール酸、オルソフタル酸など）不飽和脂肪族酸（マレイン酸、フマ−ル酸、イタコン酸など）の少なくとも一種必要に応じて脂肪酸、脂環族酸の少なくとも一種及びポリオ−ル（ネオペンチルグリコ−ル、エチレングリコ−ル）などを主成分とする樹脂である。
ポリエステル樹脂粉末に粒径２０ｎｍ以下の微細酸化珪素、ポバ−ル、デンプン、片栗粉餅粉の少なくとも一種、を１％以下存在させた組成物及びこの組成物を用いて製造したマットである。 As a result of intensive studies to achieve the above object, the present invention requires at least one of aromatic acids (terephthalic acid, isophthalic acid, orthophthalic acid, etc.) and unsaturated aliphatic acids (maleic acid, fumaric acid, itaconic acid, etc.). Depending on the above, it is a resin mainly composed of at least one of fatty acid, alicyclic acid and polyol (neopentyl glycol, ethylene glycol).
A polyester resin powder is a composition produced by using 1% or less of fine silicon oxide having a particle size of 20 nm or less, poval, starch, or starch powder of starch, and a mat produced using this composition.

本発明の組成物はガラス繊維の交点に効率的に付着する。得られたマットは良好な接着状態である。又本組成物は貯蔵中に塊状になるブロッキング現象を起こさなく、ガラス繊維に散布したとき、ガラス繊維層を抜けて下に落ちる量が少ない。また本発明品は従来からあるパウダ−接着剤に比べ軟化点が低いため接着時の加熱温度を低くすることができ、エネルギ−の節約ができる。 The composition of the present invention efficiently adheres to the intersection of glass fibers. The resulting mat is in good adhesion. In addition, the present composition does not cause a blocking phenomenon that becomes a lump during storage, and when sprayed on glass fibers, the amount that falls through the glass fiber layer is small. Further, since the product of the present invention has a lower softening point than conventional powder adhesives, the heating temperature at the time of bonding can be lowered, and energy can be saved.

本発明は上記の成分を有するポリエステルテル樹脂である。これら樹脂は１００〜３００μ粒径に粉砕する。樹脂の軟化点は５０〜７０度である。
この粉砕した樹脂に２０μ以下の微細酸化珪素、ポバ−ル、デンプン、片栗粉、餅粉の少なくとも一種を１％以下混合し均一に分散させて得られる。なおかたくり粉、餅粉もデンプンの一種であるこの組成物をガラス繊維上に散布し加熱して接着させる。 The present invention is a polyester tellur resin having the above components. These resins are pulverized to a particle size of 100 to 300 μm. The softening point of the resin is 50 to 70 degrees.
This pulverized resin is obtained by mixing at least 1% of fine silicon oxide of 20 μm or less, poval, starch, starch starch, and starch powder and uniformly dispersing them. Further, this composition, which is also a kind of starch and starch cake, is sprayed on glass fiber and heated to adhere.

イソフタール酸、フマール酸、マレイン酸、ネオペンチルグリコールで合成したポリエスに微細酸化珪素、かたくり粉を添加して親水性、ブロッキング防止性などをテストした結果は表１に示す。 Table 1 shows the results of testing the hydrophilicity and anti-blocking property by adding fine silicon oxide and hard powder to polyester synthesized with isophthalic acid, fumaric acid, maleic acid and neopentyl glycol.

得られた組成物（Ｎｏ１〜Ｎｏ３）及び市販品をガラス繊維上に散布し、１５０℃〜１７０℃で加熱、加圧しマットを作成した。得られた結果は表２に示す。 The obtained compositions (No1 to No3) and commercially available products were sprayed on glass fibers, and heated and pressurized at 150 ° C to 170 ° C to create a mat. The results obtained are shown in Table 2.
