【発明の属する技術分野】
本発明は、紫外線吸収能を有するα, β−不飽和カルボン酸エステル、光安定化能を有するα, β−不飽和カルボン酸エステル、及び芳香族ビニル化合物をラジカル反応条件下でオレフィン系樹脂に反応させて得られる変性オレフィン系重合体を含むオレフィン系樹脂組成物に関する。
本発明はまた、上記オレフィン系樹脂組成物を含有する、成形性、耐候性、紫外線吸収性、表面外観が良好で、農業用フィルム、建材、包装袋等の長期間の耐候性が要求される用途において特に有用な熱可塑性樹脂組成物に関するものである。
【0002】
【従来の技術】
外装用建材や建材用化粧シート、農業用フィルムや食品包装フィルム等の材料としては、透明性、二次加工性、耐白化性及び耐候性等の性能をバランス良く有する塩化ビニル系樹脂が従来より広く用いられている。しかしながら、塩化ビニル系樹脂は、焼却時に塩化水素等のガスを発生し、焼却炉によっては炉材の損傷を引き起こすことがある等の問題があり、その代替品としてオレフィン系樹脂を使用する例が見られるようになっている。
オレフィン系樹脂は、低コストで機械的強度、耐熱性、耐油性等に優れ、かつ透明性等の外観にも優れているため、各種の成形法で成形されて、フィルム、繊維、成形品などの広範囲な用途に使用されているが、建材用、農業用シートまたはフィルム分野といった長期間の耐候性が要求される分野では、オレフィン系樹脂に加えて、紫外線吸収剤や光安定剤等の各種の添加剤が使用される。
【0003】
しかしながら、このような添加剤の分子量は、基材であるオレフィン系樹脂に比べて相対的に小さく、また樹脂との相溶性が不十分なものも多いため、成形中にこれらが揮散してしまい十分な耐候性改良効果が得られなかったり、そのブリードやプレートアウトによる加工設備、特にロールの汚染やその汚染の転写等による製品外観の不良等の問題があった。
特に、長期間の使用を前提とする建材用化粧シート等の用途においては下地の印刷層の保護を目的として多量の紫外線吸収剤が配合されるので、これらの問題の解決は重要である。
【0004】
これを解決するため、特開昭63−227575号公報において、分子内に重合性不飽和基を有する紫外線吸収剤を樹脂の製造時に添加して共重合体とすることにより、樹脂骨格に紫外線吸収剤を導入する方法が提案されている。しかしながら、この方法はアクリル系の樹脂やメタクリル系の樹脂については有効であるが、チーグラー・ナッタ触媒等のいわゆる配位アニオン触媒を用いて製造されるオレフィン系樹脂の場合は、紫外線吸収剤自体がこのような触媒に対して触媒毒して作用するため、重合反応が進行しなくなる等の問題があり、この手法を適用することは困難であった。
【0005】
そこで、オレフィン系樹脂については、分子内に不飽和基を有する紫外線吸収剤をポリプロピレン系樹脂とラジカル反応条件下で溶融混練して樹脂中に紫外線吸収剤を導入する方法が提案されている(特開平8−208765号公報)。しかしながら、この方法によっても耐候性が不十分な場合があり、特にポリオレフィン系樹脂に多く用いられるヒンダードアミン系光安定剤を配合した場合は、そのプレートアウトについては改良効果が見られないのみならず、耐候性についても改良効果が不十分であった。
【0006】
プレートアウトやブリードについてはヒンダードアミン系光安定剤とエチレンとの共重合体である重合体型光安定剤を用いると一定の改良効果が得られるものの、耐候性については依然不十分なものであった。
一方、特開平7−11031号公報には、上記のような反応性を両者ともに有する紫外線吸収剤と光安定剤とをポリプロピレン系樹脂に反応させることが提案されているが、反応性が低く、残留する未反応の紫外線吸収剤や光安定剤のため、プレートアウトやブリード等の問題は十分には解決されてはいない。
【0007】
【発明が解決しようとする課題】
本発明は、上述のような問題点のない、成形性、ブリード、プレートアウト( ロール汚れ) 、耐候性、及び透明性に優れたオレフィン系樹脂組成物及びこれに基づく耐候性の良好な熱可塑性樹脂組成物を提供することを目的としている。
【0008】

【0011】
【発明の実施の形態】
以下、本発明を詳細に説明する。
(1)オレフィン系樹脂組成物の各成分
成分(A):オレフィン系樹脂
本発明の組成物の原料として用いるオレフィン系樹脂は、炭素原子数2〜12、好ましくは2〜8のα−オレフィンの単独重合体又はそれらを主成分とする共重合体である。これらのα−オレフィンの具体例としては、エチレン、プロピレン、1−ブテン、1−ヘキセン、3−メチル−1−ブテン、3−メチル−1−ペンテン、4−メチル−1−ペンテン、3,3−ジメチル−1−ブテン、4,4−ジメチル−1−ペンテン、3−メチル−1−ヘキセン、4−メチル−1−ヘキセン、4,4−ジメチル−1−ヘキセン、5−メチル−1−ヘキセン、アリルシクロペンタン、アリルシクロヘキサン、アリルベンゼン、3−シクロヘキシル−1−ブテン、ビニルシクロプロパン、ビニルシクロヘキサン、2−ビニルビシクロ[2.2.1]−ヘプタンなどを挙げることができる。これらのα−オレフィンは1種類を用いても、また、2種以上を用いても差し支えない。
【0012】
これらのα−オレフィンのうちで好ましいものとしては、エチレン、プロピレン、1−ブテン、1−ヘキセン、3−メチル−1−ブテン、3−メチル−1−ペンテン、4−メチル−1−ペンテン、3−メチル−1−ヘキセン等であり、エチレン、プロピレン、1−ブテン、3−メチル−1−ブテン又は4−メチル−1−ペンテンが更に好ましい。
上記のようなオレフィン系樹脂の中でもプロピレン系樹脂、即ちプロピレン単独重合体及びプロピレンを主体とする他のα−オレフィンとの共重合体が特に好ましく、具体的にはアイソタクティックポリプロピレン、シンジオタクティックポリプロピレン、プロピレン−エチレン共重合体、プロピレン−ブテン共重合体等が挙げられる。また、これらのプロピレン系樹脂を混合して用いることもできる。
【0013】
成分(B):紫外線吸収能を有するα , β−不飽和カルボン酸エステル
成分(B)の紫外線吸収能を有するα, β−不飽和カルボン酸エステルとしては、紫外線吸収性を示す官能基を1個以上分子中に有するα, β−不飽和カルボン酸エステルであれば特に限定されることなく使用できるが、紫外線吸収性を示す官能基としては2−(2’−ヒドロキシフェニル)ベンゾトリアゾール基、又は2−ヒドロキシベンゾフェノン基が好ましく、特に着色性等を考慮すると2−(2’−ヒドロキシフェニル)ベンゾトリアゾール基が好ましい。
例えば本発明に用いるのに好適なベンゾトリアゾール基を含有するα, β−不飽和カルボン酸エステルは下式(1)により表わされるものである。
【0014】

【0015】
上記式(1)において置換基R1 、R2 及びR3 の少なくとも1つは、α, β−不飽和カルボン酸エステル基を有する置換基であり、残りの基は水素、炭素原子数1〜10の直鎖状、分岐状もしくは環状の脂肪族炭化水素基、アルコキシ基、もしくは芳香族炭化水素基、又はハロゲン原子である。また置換基R2 及びR3 の位置は、ヒドロキシル基に対してオルト位、メタ位、パラ位のいずれでもよく、また置換基R1 の位置も特に限定はされない。
【0016】
α, β−不飽和カルボン酸残基の代表的な例としては例えば、アクリル酸、メタクリル酸等のモノカルボン酸の残基やマレイン酸、フマル酸等のジカルボン酸の残基が挙げられ、中でもアクリル酸及びメタクリル酸の残基が好ましい。なおジカルボン酸の残基の場合、そのエステル結合の数はモノエステル及びジエステルのどちらでもよい。
【0017】
このような紫外線吸収能を有するα, β−不飽和カルボン酸エステルの具体例としては、2−ヒドロキシ−4−(2′−メタクリロイルオキシエトキシ)ベンゾフェノン、2−ヒドロキシ−4−(2′−アクリロイルオキシエトキシ)ベンゾフェノン、2−(2′−ヒドロキシ−5′−メタクリロイルオキシエトキシフェニル)ベンゾトリアゾール、2−(5′−アクリロイルオキシエトキシ−2′−ヒドロキシフェニル)ベンゾトリアゾール等が挙げられる。
【0018】
成分(C):光安定化能を有するα , β−不飽和カルボン酸エステル
成分(C)の光安定化能を有するα, β−不飽和カルボン酸エステルとしては、光安定化能を示す官能基を1個以上分子中に有するα, β−不飽和カルボン酸エステルであれば特に限定されることなく使用しうるが、光安定化能を示す官能基としてはピペリジン環を有するものが好ましく、特に下記式(2)で示される構造式を有する、いわゆるヒンダードアミン系化合物が好ましい。
【0019】
【化2】
【0020】
上記式(2)において置換基R4 は水素原子又は炭素原子数1〜4のアルキル基又はアルコキシ基であり、R5 はα, β−不飽和カルボン酸エステル基を有する置換基である。
α, β−不飽和カルボン酸残基としては、上記(B)成分の項で例示したものと同様のものが好適に使用できる。特に好ましいものはアクリル酸及びメタクリル酸の残基である。

【0022】
成分(D):芳香族ビニル化合物

【0023】
(2)オレフィン系樹脂組成物の組成
本発明のオレフィン系樹脂組成物の原料となる混合物中の各成分の配合量としては、(A)成分のポリオレフィン樹脂の使用量を100重量部としたとき、(B)成分の紫外線吸収能を有するα, β−不飽和カルボン酸エステルの配合量は、0.1〜20重量部、好ましくは0.5〜15重量部の範囲、(C)成分の光安定化能を有するα, β−不飽和カルボン酸エステルの配合量は、0.1〜20重量部、好ましくは0.5〜15重量部の範囲、また、(D)成分の芳香族ビニル化合物の配合量は、0.1〜50重量部、好ましくは0.5〜30重量部の範囲である。
【0024】
(B)成分又は(C)成分の配合量が0.1重量部未満の場合は、添加の目的である紫外線吸収能や耐光安定性が不足する。一方、これらの配合量が20重量部を越えても、その増量に見合う効果の向上は見られず、逆にこれらがブリード等の原因となる可能性が大きくなり好ましくない。
(D)成分の配合量が0.1重量部未満では、(B)成分や(C)成分の(A)成分との反応性が低下してしまい、未反応物の残留が起きやすくなる。一方、これを50重量部を越えて配合した場合は、ポリオレフィン樹脂の柔軟性が阻害されたり、得られる組成物の透明性が悪化することがあるので、やはり好ましくない。
【0025】
なお、(B)成分の紫外線吸収能を有するα, β−不飽和カルボン酸エステルと(C)成分の光安定化能を有するα, β−不飽和カルボン酸エステルとの配合量比は、(B)成分/(C)成分の重量比で1/99〜99/1の範囲とするのが好ましく、特に10/90〜90/10の範囲であるのが好ましい。この量比が上記の範囲を外れた場合は、オレフィン系樹脂組成物やこれを含む熱可塑性樹脂組成物、及びこれらから得られる成形体の紫外線吸収能や耐候性が不十分となる傾向が著しくなる。
【0026】
また、(B)成分の紫外線吸収能を有するα, β−不飽和カルボン酸エステルと(C)成分の光安定化能を有するα, β−不飽和カルボン酸エステルとの合計量に対する(D)成分の芳香族ビニル化合物の配合量は、(D)成分/((B)成分+(C)成分)の重量比で1/99〜99/1の範囲、好ましくは10/90〜90/10の範囲である。(D)成分の芳香族ビニル化合物を添加しなかったり、その含有量や含有割合が低すぎると、(A)成分であるオレフィン系樹脂への(B)成分の紫外線吸収能を有するα, β−不飽和カルボン酸エステルや(C)成分の光安定化能を有するα, β−不飽和カルボン酸エステルの反応性が低下して、未反応物が組成物中に残留しやすくなり、これを含む組成物等を成形加工する際に、ロールが汚れたり、ブリードアウトによって成形品の外観が悪化することが多い。
【0027】
(3)ラジカル発生剤
上述の各成分を含有する混合物をラジカル反応条件下で反応させて本発明のオレフィン系樹脂組成物を得るための用いるラジカル発生剤としては、例えばt−ブチルヒドロパーオキシド、クメンヒドロパーオキシド、2,5−ジメチルヘキサン−2,5−ジヒドロパーオキシド、t−ブチルパーオキシベンゾエート、ベンゾイルパーオキシド、ジクミルパーオキシド、1,3−ビス(t−ブチルパーオキシイソプロピル)ベンゼン、ジブチルパーオキシド、メチルエチルケトンパーオキシド、過酸化カリウム、過酸化水素等の有機及び無機過酸化物、2,2′−アゾビスイソブチロニトリル、2,2′−アゾビス(イソブチルアミド)ジハライド、2,2′−アゾビス[2−メチル−N−(2−ヒドロキシエチル)プロピオンアミド]、アゾジ−t−ブタン等のアゾ化合物、及びジクミル等の炭素ラジカル発生剤等が例示できる。これらのラジカル発生剤は、(B)成分の紫外線吸収能を有するα, β−不飽和カルボン酸エステルや(C)成分の光安定化能を有するα, β−不飽和カルボン酸エステルの種類や反応条件に応じて適宜選択すればよく、また2種以上を併用してもよい。このラジカル発生剤は有機溶剤等に溶解して用いることもできる。
【0028】
ラジカル発生剤の使用量としては、上記オレフィン系樹脂100重量部に対して0.01〜30重量部、好ましくは0.05〜10重量部の範囲とするのが良い。ラジカル発生剤の使用量が0.01重量部未満では、(B)成分や(C)成分の(A)成分への付加量が低下して未反応物が残留しやすくなるので好ましくない。一方30重量部を越えて使用すると、例えばポリプロピレン系樹脂では主鎖の切断による劣化が進行し、ポリエチレン系樹脂ではゲル化が著しくなるなど、オレフィン系樹脂が本来有する性質を著しく損なうため、やはり好ましくない。
【0029】
(4)オレフィン系樹脂組成物の調製
本発明のオレフィン系樹脂組成物は、上述の各成分をラジカル反応条件下で反応させて調製されるが、その調製に際しては、溶融混練法、溶液法、及び懸濁法等の方法が特に限定することなく使用できる。好ましい調整方法は溶融混練法である。
溶融混練法に用いる混練機としては、ラボプラストミル、一軸または二軸押出機等の押出機、横型二軸多円板装置、横型二軸表面更新機等の横型二軸撹拌機、ダブルヘリカルリボン撹拌機等の縦型二軸撹拌機等が挙げられる。溶融混練の温度は、ラジカル発生剤からラジカルが生成し、かつオレフィン系樹脂が溶融状態になる温度であれば特に限定されないが、用いるオレフィン系樹脂の劣化防止を考慮すれば300℃以下が好ましい。混練時間は、0.1〜10分、好ましくは0.5〜5分の範囲とするのがよい。
【0030】
各配合成分及びラジカル発生剤の添加方法としては、予め(A)成分のオレフィン系樹脂とその他の成分を一括混練してドライブレンドとする方法、(B)〜(D)成分又はラジカル発生剤のいずれかと(A)成分のオレフィン系樹脂とをドライブレンドしておいて、これを溶融混練する途中で残る成分を添加する方法、あるいは溶融状態となった(A)成分のオレフィン系樹脂にその他の配合成分とラジカル発生剤とを添加混合する方法等がある。
【0031】
なお、混練時の粘度調節や反応効率向上を目的としてキシレン等の有機溶剤を、例えばオレフィン系樹脂100重量部に対して0.1〜5重量部程度添加してもよい。また未反応物や添加した溶剤等を除去するために、前記の混練機や撹拌機の内部を、例えば0.1〜10mmHg(絶対圧)程度の減圧にしてもよい。また溶液法においては、沸点が100℃以上のハロゲン置換または非置換の芳香族炭化水素系の溶剤、例えばクロルベンゼン、キシレン等に各成分を溶解し、通常80〜120℃程度の温度で、2〜8時間程度反応させる方法を用いることができる。
【0032】
(5)熱可塑性樹脂組成物
上記のようにして調製されるオレフィン系樹脂組成物は、その紫外線吸収能と光安定化能を活かして、他の熱可塑性樹脂に添加して組成物として用いることができる。
用いることができる熱可塑性樹脂としては、オレフィン系樹脂、スチレン系樹脂、塩化ビニル系樹脂等が挙げられる。中でも、オレフィン系樹脂が好ましく、特にポリエチレン、ポリプロピレン、エチレン−プロピレン共重合体、エチレン−ブテン共重合体、エチレン−酢酸ビニル共重合体、エチレン−アクリル酸共重合体が好ましい。熱可塑性樹脂組成物中の本発明の上記オレフィン系樹脂組成物の含有量は、熱可塑性樹脂と本発明のオレフィン系樹脂組成物との合計量を100重量%とした時に、0.1〜50重量%であるのが好ましく、0.5〜30重量%であるのが更に好ましい。
【0033】
またこの熱可塑性樹脂組成物には、目的に応じて各種の添加剤、例えば酸化防止剤、中和剤、増核剤、滑剤、流動性改良剤、離型剤、充填剤、無機フィラー、着色剤等を、本発明の効果を損なわない範囲で添加してもよい。
上記の熱可塑性樹脂組成物は、熱可塑性樹脂の成形に通常用いられる成形方法、即ち押出成形法、射出成形法、圧縮成形法、カレンダー加工法などにより所望の形状に成形できる。また、この組成物をTダイ成形、インフレーション成形等して得られるフィルム又はシートは、耐候性、紫外線吸収性、表面外観が良好であるので、農業用フィルム、建材、包装袋等の長期間の耐候性が要求される用途に用いるのに特に好適である。
【0034】

BACKGROUND OF THE INVENTION
The present invention relates to an α, β-unsaturated carboxylic acid ester having ultraviolet absorbing ability, an α, β-unsaturated carboxylic acid ester having light stabilizing ability, and an aromatic vinyl compound as an olefin resin under radical reaction conditions. The present invention relates to an olefin resin composition containing a modified olefin polymer obtained by reaction.
The present invention also requires the long-term weather resistance of agricultural films, building materials, packaging bags, etc., containing the olefin resin composition, having good moldability, weather resistance, ultraviolet absorption, and surface appearance. The present invention relates to a thermoplastic resin composition that is particularly useful in applications.
[0002]
[Prior art]
As materials for exterior building materials, building material decorative sheets, agricultural films, food packaging films, etc., vinyl chloride resins that have a balance of performance such as transparency, secondary processability, whitening resistance, and weather resistance have been conventionally used. Widely used. However, vinyl chloride resins generate hydrogen chloride and other gases during incineration, which may cause damage to furnace materials depending on the incinerator. Examples of using olefin resins as an alternative are It can be seen.
Olefin-based resins are low in cost, excellent in mechanical strength, heat resistance, oil resistance, etc., and also have excellent appearance such as transparency, so they are molded by various molding methods, such as films, fibers, molded products, etc. In fields where long-term weather resistance is required, such as for building materials, agricultural sheets or films, in addition to olefinic resins, various types such as UV absorbers and light stabilizers are used. The additives are used.
[0003]
However, the molecular weight of such additives is relatively small compared to the base olefin resin, and many of them have insufficient compatibility with the resin. There were problems such as insufficient weather resistance improvement effects, processing equipment due to bleed and plate-out, particularly defective product appearance due to contamination of the roll and transfer of the contamination.
In particular, in applications such as decorative sheets for building materials that are assumed to be used for a long period of time, a large amount of an ultraviolet absorber is blended for the purpose of protecting the printed layer of the base, so it is important to solve these problems.
[0004]
In order to solve this problem, in Japanese Patent Laid-Open No. 63-227575, an ultraviolet absorber having a polymerizable unsaturated group in the molecule is added during the production of the resin to form a copolymer, whereby the resin skeleton absorbs ultraviolet rays. A method of introducing an agent has been proposed. However, this method is effective for acrylic resins and methacrylic resins. However, in the case of an olefin resin produced using a so-called coordination anion catalyst such as a Ziegler-Natta catalyst, the ultraviolet absorber itself is used. Since such a catalyst acts as a catalyst poison, there is a problem that the polymerization reaction does not proceed, and it is difficult to apply this method.
[0005]
Therefore, for olefin resins, a method has been proposed in which an ultraviolet absorber having an unsaturated group in the molecule is melt kneaded with a polypropylene resin under radical reaction conditions and the ultraviolet absorber is introduced into the resin (special feature). (Kaihei 8-208765). However, the weather resistance may be insufficient even by this method, especially when blended with a hindered amine light stabilizer often used in polyolefin resin, not only the improvement effect is not seen for the plate-out, The effect of improving weather resistance was also insufficient.
[0006]
With regard to plate-out and bleed, when a polymer-type light stabilizer that is a copolymer of a hindered amine light stabilizer and ethylene is used, a certain improvement effect is obtained, but the weather resistance is still insufficient.
On the other hand, in Japanese Patent Laid-Open No. 7-11031, it has been proposed to react a polypropylene resin with an ultraviolet absorber and a light stabilizer both having the above-described reactivity, but the reactivity is low. Due to the remaining unreacted UV absorber and light stabilizer, problems such as plate-out and bleeding are not sufficiently solved.
[0007]
[Problems to be solved by the invention]
The present invention is an olefin resin composition excellent in moldability, bleed, plate-out (roll dirt), weather resistance, and transparency, and thermoplastic having good weather resistance based on the above, without the above-mentioned problems. The object is to provide a resin composition.
[0008]

[0009]
Further, the gist of the present invention is that the (A) component olefin resin is a propylene resin, the above olefin resin composition, and the component (B) is an α, β-unsaturated carboxylic acid ester having ultraviolet absorbing ability. Those having a benzotriazole group, in particular, the component (B) also exist in the above-mentioned olefin resin composition, which is a 2- (2′-hydroxyphenyl) benzotriazole derivative.
[0010]
Another gist of the present invention resides in the olefin-based resin composition in which the α, β-unsaturated carboxylic acid ester having the light stabilizing ability of the component (C) is a hindered amine compound. It exists also in the above-mentioned olefin resin composition obtained by melt-kneading a mixture containing (A) to (D) in the presence of a radical generator.
Furthermore, another gist of the present invention is a thermoplastic resin composition containing a thermoplastic resin and the olefin resin composition, wherein the total amount of the thermoplastic resin and the olefin resin composition is determined. A thermoplastic resin composition having a content of the olefin resin composition of 0.1 to 50% by weight and a film or sheet made of this thermoplastic resin composition when the content is 100% by weight. Yes.

[0054]
[Table 1]
[0055]
[Table 2]
[0056]
(4) Evaluation of results
The following points are clear from the above examples and comparative examples.
1) When component (D) is not included (Production Example 3 → Comparative Example 1, Production Example 4 → Comparative Example 2), even if a reactive UV absorber or light stabilizer is used, the reaction does not occur. Since the amount of these additions is small, the ultraviolet transmittance is insufficient, and the remaining unreacted materials cause poor roll dirt and haze.
2) In the case where either one of component (B) or component (C) is not contained (Production Example 5 → Comparative Examples 3-5, Production Example 6 → Comparative Example 6, Production Example 7 → Comparative Example 7), the weather resistance (Comparative Examples 3, 4, 6, and 7) are insufficient. When the amount of the polymeric light stabilizer capable of preventing roll contamination is increased while covering this (Comparative Example 5), haze deteriorates.
In Comparative Examples 6 and 7, which do not contain an ultraviolet absorber, there is no ultraviolet absorbing ability.
3) As an olefin-based resin composition, one is prepared by kneading a non-reactive UV absorber (Production Example 8) and the other is a non-reactive light stabilizer (Production Example 9), and is thermoplastic. In the example (Comparative Example 8) in which these were used in combination at the stage of the resin composition, roll contamination occurred.
[0057]
