Abstract
Description
本発明は、柔軟性、伸び性および成形時の流動性に優れた液晶ポリマー組成物に関する。 The present invention relates to a liquid crystal polymer composition excellent in flexibility, extensibility, and fluidity during molding.
サーモトロピック液晶ポリマー（以下、液晶ポリマーまたはＬＣＰと略称する）は、耐熱性、高強度、耐薬品性、寸法精度、低吸水性等に優れているため、各種用途にその使用が拡大しつつある。 Thermotropic liquid crystal polymer (hereinafter abbreviated as liquid crystal polymer or LCP) is excellent in heat resistance, high strength, chemical resistance, dimensional accuracy, low water absorption, etc., and therefore its use is expanding in various applications. .
特にパーソナル・コンピューターや携帯電話、スマートフォン、自動車等の電気・電子分野においては、部品の高集積度化、小型化、薄肉化、低背化が急速に進んでおり、これに伴う樹脂部材の薄肉化が求められている。そこで、液晶ポリマーはその優れた成形性、すなわち薄肉流動性が良好であり、かつバリが出ないという他の樹脂にない特徴を生かして、その使用量が大幅に増大している。 In particular, in the electrical and electronic fields such as personal computers, mobile phones, smartphones, automobiles, etc., there is a rapid increase in the degree of integration, miniaturization, thinning, and low profile of parts. Is required. Therefore, the amount of the liquid crystal polymer used is greatly increased by taking advantage of its excellent moldability, i.e., thin-walled fluidity, and no characteristics of other resins such as no burrs.
しかし、液晶ポリマーは分子構造が剛直であるが故に柔軟性や伸び性に劣るといった欠点がある。電気・電子分野で重要な部品の１つであるコネクタ部品においては、部品同士の接続に嵌合が必要であるため、柔軟性や伸び性も求められる。材料評価の観点では、引張強度と引張破断伸びの積である抗張積が１つの基準となり、強度と伸びを兼ね備えた、抗張積の大きい液晶ポリマーが求められている。 However, since the liquid crystal polymer has a rigid molecular structure, it has a drawback of being inferior in flexibility and extensibility. In connector parts that are one of the important parts in the electric / electronic field, fitting is required for connection between the parts, so flexibility and stretchability are also required. From the viewpoint of material evaluation, the tensile product, which is the product of tensile strength and tensile elongation at break, is one criterion, and a liquid crystal polymer having a high tensile product that has both strength and elongation is required.
特許文献１には、靱性に優れた液晶ポリエステルアミド樹脂組成物について記載されている。しかし、特許文献１に記載の樹脂組成物は成形加工温度ならびに溶融粘度が高いため、成形加工性が不十分であるといった課題があった。 Patent Document 1 describes a liquid crystal polyesteramide resin composition having excellent toughness. However, since the resin composition described in Patent Document 1 has a high molding process temperature and melt viscosity, there is a problem that the moldability is insufficient.
特許文献２には、引張物性に優れた液晶ポリマー組成物として、液晶ポリマーにエポキシ基含有エチレン共重合体および表面無処理のガラス繊維を含有させた組成物が提案されている。しかしながら、特許文献２に記載の液晶ポリマー組成物は、表面無処理のガラス繊維を含有することによって溶融粘度が高くなり、引張伸びの改善が不十分であるといった課題があった。 Patent Document 2 proposes a composition in which an epoxy group-containing ethylene copolymer and non-surface-treated glass fibers are contained in a liquid crystal polymer as a liquid crystal polymer composition having excellent tensile properties. However, the liquid crystal polymer composition described in Patent Document 2 has a problem that the melt viscosity is increased by containing glass fibers having no surface treatment, and improvement in tensile elongation is insufficient.
本発明の目的は、流動性および機械強度を損なうことなく、柔軟性および伸び性が改良された液晶ポリマー組成物を提供することにある。 An object of the present invention is to provide a liquid crystal polymer composition having improved flexibility and extensibility without impairing fluidity and mechanical strength.
本発明者らは、液晶ポリマーの柔軟性および伸び性の改善について鋭意検討した結果、液晶ポリマーに、エポキシ基含有エチレン共重合体および板状充填材を含有させることにより、流動性および機械強度を損なうことなく柔軟性および伸び性が改善されることを見出し、本発明を完成させるに至った。 As a result of intensive investigations on the improvement of flexibility and elongation of the liquid crystal polymer, the inventors of the present invention have improved fluidity and mechanical strength by adding an epoxy group-containing ethylene copolymer and a plate-like filler to the liquid crystal polymer. The present inventors have found that the flexibility and extensibility can be improved without impairing the present invention, and have completed the present invention.
すなわち本発明は、液晶ポリマー１００重量部、エポキシ基含有エチレン共重合体１〜３０重量部、および板状充填材１〜３０重量部を含有する液晶ポリマー組成物を提供する。 That is, the present invention provides a liquid crystal polymer composition containing 100 parts by weight of a liquid crystal polymer, 1 to 30 parts by weight of an epoxy group-containing ethylene copolymer, and 1 to 30 parts by weight of a plate-like filler.
本発明の液晶ポリマー組成物は、流動性および機械強度を損なうことなく、柔軟性および伸び性に優れるため、接続に嵌合等が求められる部品や小型化および薄肉化が求められる部品の成形用樹脂として好適に用いることができる。 The liquid crystal polymer composition of the present invention is excellent in flexibility and extensibility without impairing fluidity and mechanical strength, and therefore, for molding parts that require fitting or the like for connection or parts that require miniaturization and thinning. It can be suitably used as a resin.

<Bending strength, flexural modulus>
A strip-shaped bending test piece (length 127 mm × width 12.7 mm × thickness 3.2 mm) was produced under the same conditions as those of the molded piece used for measuring the deflection temperature under load. The bending test was performed in accordance with ASTM D790 using a INSTRON 5567 (universal testing machine manufactured by Instron Japan Company Limited) at a test speed of 1.3 mm / min and a span distance of 50 mm. .
〈Ｉｚｏｄ衝撃強度〉
荷重たわみ温度測定に用いた試験片と同じ試験片を用いて、試験片の中央を長さ方向に垂直に切断し、ノッチを付けた。長さ６３．５ｍｍ、幅１２．７ｍｍ、厚さ３．２ｍｍの短冊状試験片を得、ＡＳＴＭ Ｄ２５６に準拠して測定した。
<Izod impact strength>
Using the same specimen as the specimen used for measuring the deflection temperature under load, the center of the specimen was cut perpendicularly in the length direction to give a notch. A strip-shaped test piece having a length of 63.5 mm, a width of 12.7 mm, and a thickness of 3.2 mm was obtained and measured according to ASTM D256.
表１に示す通り、エポキシ基含有エチレン共重合体および板状充填材を含有する実施例１〜５の液晶ポリマー組成物は、比較例１、比較例２、比較例４および比較例５の液晶ポリマー組成物と比較して、流動性および機械強度を損なうことなく、低弾性率化による柔軟性の改善、および伸びが向上することが理解される。 As shown in Table 1, the liquid crystal polymer compositions of Examples 1 to 5 containing an epoxy group-containing ethylene copolymer and a plate-like filler are the liquid crystals of Comparative Example 1, Comparative Example 2, Comparative Example 4 and Comparative Example 5. It is understood that the improvement in flexibility and the elongation are improved by lowering the elastic modulus without impairing the fluidity and mechanical strength as compared with the polymer composition.
比較例３の液晶ポリマー組成物は、柔軟性に優れるものの、溶融粘度が高く流動性が劣るものであった。 Although the liquid crystal polymer composition of Comparative Example 3 was excellent in flexibility, it had high melt viscosity and poor fluidity.
また、実施例１〜５の液晶ポリマー組成物は、比較例１〜５の液晶ポリマー組成物と比較して抗張積が大きく、強度と伸びのバランスの良い材料であることが理解される。 In addition, it is understood that the liquid crystal polymer compositions of Examples 1 to 5 are materials having a large tensile product and a good balance between strength and elongation as compared with the liquid crystal polymer compositions of Comparative Examples 1 to 5.
