Description

本発明は、特定のアクリル酸エステル系ゴム強化樹脂と特定のヒンダードアミン系光安定剤を含有してなる樹脂組成物を押出成形してなる耐溶剤白化性に優れる建材用押出成形品に関するものである。 The present invention relates to an extruded product for building materials having excellent solvent whitening resistance obtained by extrusion molding a resin composition containing a specific acrylic ester rubber-reinforced resin and a specific hindered amine light stabilizer. .

従来から、雨樋やデッキ材、あるいは床材といった建材分野においては、必要とされる物性、特に成形性、さらに経済性の点で優れた性能を有する熱可塑性樹脂として、塩化ビニル樹脂(PVC)が多用されている。但し、PVCは耐候性に劣るため太陽光が直接当たるような用途では、耐候性樹脂材料であるAES樹脂やASA樹脂等への代替が近年進んできている。 Conventionally, in the field of building materials such as rain gutters, deck materials, and flooring materials, polyvinyl chloride resin (PVC) is a thermoplastic resin that has excellent properties in terms of required physical properties, especially moldability and economy. Is frequently used. However, since PVC is inferior in weather resistance, replacement with AES resin, ASA resin, or the like, which is a weather resistant resin material, has been progressing in recent years in applications where sunlight is directly applied.

しかし、住宅の耐久年数の延長等によりこれらAES樹脂やASA樹脂等に要求される耐候性のレベルが年々高くなってきているため、これらの樹脂成分中にMMA成分を導入する試みがなされているが、単純にMMA成分を導入しただけでは耐候性の向上は認められるものの、溶剤の種類によってはその付着により容易に表面の白化が発生し商品価値を著しく損なうという欠点を有していた。 However, since the level of weather resistance required for these AES resins and ASA resins has been increasing year by year due to the extension of the durable years of homes, attempts have been made to introduce MMA components into these resin components. However, although the weather resistance can be improved by simply introducing the MMA component, it has the disadvantage that the surface is easily whitened due to the adhesion depending on the kind of the solvent and the commercial value is remarkably impaired.

上記欠点の解決策として、AES樹脂やASA樹脂に対してポリオレフィン系樹脂やナイロン樹脂あるいはPBT樹脂等の結晶性樹脂を混合することが考えられるが、スチレン系樹脂はこのような結晶性樹脂との相溶性に劣るため、成形品の外観が著しく損なわれる、あるいは層剥離現象が発生する等の不具合が発生するという欠点を有している。

As a solution to the above drawbacks, it is conceivable to mix a crystalline resin such as polyolefin resin, nylon resin or PBT resin with AES resin or ASA resin. Since the compatibility is inferior, the appearance of the molded product is remarkably impaired, or a defect such as a delamination phenomenon occurs.

The present invention will be described in detail below.
The acrylic acid ester rubber-like polymer constituting the acrylic acid ester rubber reinforced resin (A) in the present invention is an acrylic acid ester type monomer such as methyl acrylate, ethyl acrylate, butyl acrylate, and 2-ethylexyl acrylate. It is a rubber-like polymer obtained by polymerizing other monomers such as butadiene, styrene, silicon and the like as a main component. As the polymerization method, an emulsion polymerization method is generally used, but other polymerization methods such as a solution polymerization method and a bulk polymerization method, or any combination thereof may be used depending on the purpose.

また、本発明においては、シアン化ビニル系単量体および(メタ)アクリル酸エステル系単量体と共に必要に応じて他の共重合可能な単量体、例えば、スチレン、α−メチルスチレン、o−メチルスチレン、m−メチルスチレン、p−メチルスチレン、α−メチル−p−メチルスチレン、ハロゲン化スチレン、エチルスチレン、p−イソプロピルスチレン、p−t−ブチルスチレン、2,4−ジメチルスチレン、ジビニルベンゼン等の芳香族ビニル系単量体、N−フェニルマレイミド、N−シクロヘキシルマレイミド等のマレイミド系単量体、アクリル酸、メタクリル酸等の不飽和カルボン酸等を使用することも可能である。
Examples of the (meth) acrylate ester monomer constituting the acrylate ester rubber-reinforced resin (A) in the present invention include methyl (meth) acrylate, ethyl (meth) acrylate, propyl (meth) acrylate, and butyl (meth) ) Acrylate, 2-ethylexyl acrylate and the like, and examples of the vinyl cyanide monomer include acrylonitrile, methacrylonitrile, ethacrylonitrile, fumaronitrile, etc. it can.

これらアクリル酸エステル系ゴム強化樹脂(A)を構成するアクリル酸エステル系ゴム状重合体が5重量%未満では十分な強度が得られず30重量%を超えると成形性が大幅に低下する。
また(メタ)アクリル酸エステル系単量体が30重量%未満では十分な耐候性が得られず、90重量%を超えると成形性の低下がする。シアン化ビニル系単量体5重量%未満では十分な強度が得られず、30重量%を超えると初期着色や熱安定性の低下等の不具合が発生する。さらに共重合可能な他のビニル系単量体が60重量%を超えると十分な耐候性が得られないため好ましくない。
また、上記アクリル酸エステル系ゴム強化樹脂(A)のメルトフローレイト(220℃、10kg荷重:ASTM D-1238に準拠)は、5g/10分〜30g/10分の範囲であることが必要である。メルトフローレイトが5g/10分未満、あるいは30g/10分を超えると押出成形性が著しく損なわれるため好ましくない。
When the acrylate ester rubber-like polymer constituting the acrylate ester rubber-reinforced resin (A) is less than 5% by weight, sufficient strength cannot be obtained, and when it exceeds 30% by weight, the moldability is greatly lowered.
Further, if the (meth) acrylic acid ester monomer is less than 30% by weight, sufficient weather resistance cannot be obtained, and if it exceeds 90% by weight, the moldability is lowered. If it is less than 5% by weight of the vinyl cyanide monomer, sufficient strength cannot be obtained, and if it exceeds 30% by weight, problems such as initial coloring and deterioration of thermal stability occur. Furthermore, if the copolymerizable other vinyl monomer exceeds 60% by weight, it is not preferable because sufficient weather resistance cannot be obtained.

If the melt flow rate is less than 5 g / 10 minutes or more than 30 g / 10 minutes, the extrusion moldability is remarkably impaired.

上記アクリル酸エステル系ゴム強化樹脂(A)は、アクリル酸エステル系ゴム状重合体の存在下に(メタ)アクリル酸エステル系単量体、シアン化ビニル系単量体および共重合可能な他のビニル系単量体を重合してなるグラフト重合体単独または該グラフト重合体と、(メタ)アクリル酸エステル系単量体、シアン化ビニル系単量体および共重合可能な他のビニル系単量体を重合してなる共重合体との混合物であってもよく、最終的に得られるアクリル酸エステル系ゴム強化樹脂(A)としての各種成分が上記の組成割合であればよい。

該ヒンダードアミン光安定剤(B)の分子量が600未満では造粒あるいは成形の際に加熱されることにより、容易に蒸散してしまうため金型汚染の発生や十分な耐候性が得られない等の不具合が発生し、また分子量が1500を超えても、単位重量あたりのアミン濃度が低下するため耐候性が低下する不具合が発生する。
また、該ヒンダードアミン光安定剤(B)は、アクリル酸エステル系ゴム強化樹脂(A)100重量部に対して0.1〜5重量部の範囲で配合されるものであり、0.1重量部未満ではその効果が得られず、また5重量部を超えると金型汚染のために外観不良となり易いため好ましくない。
When the molecular weight of the hindered amine light stabilizer (B) is less than 600, it is easily evaporated when heated during granulation or molding, so that mold contamination or sufficient weather resistance cannot be obtained. Even if a malfunction occurs and the molecular weight exceeds 1500, the amine concentration per unit weight is lowered, so that the weather resistance is degraded.
Moreover, this hindered amine light stabilizer (B) is mix | blended in the range of 0.1-5 weight part with respect to 100 weight part of acrylic ester rubber-reinforced resin (A), 0.1 weight part If it is less than 5, the effect cannot be obtained, and if it exceeds 5 parts by weight, the appearance is likely to be poor due to mold contamination, which is not preferable.

本発明においては、さらに上記ヒンダードアミン光安定剤(B)に加えてバルク重合法により製造されたABS樹脂(C)1〜10重量部を添加することにより、さらに耐溶剤白化性を改良することができる。但し、その添加量が増えると耐候性が低下する傾向があるため、その添加量は10重量部が上限である。 In the present invention, the solvent whitening resistance can be further improved by adding 1 to 10 parts by weight of the ABS resin (C) produced by the bulk polymerization method in addition to the hindered amine light stabilizer (B). it can. However, since the weather resistance tends to decrease as the addition amount increases, the upper limit of the addition amount is 10 parts by weight.

更に上記樹脂組成物には顔料、染料、酸化防止剤、熱安定剤、紫外線吸収剤、帯電防止剤等を必要に応じて添加することができる。 Furthermore, pigments, dyes, antioxidants, heat stabilizers, ultraviolet absorbers, antistatic agents, and the like can be added to the resin composition as necessary.

また、上記樹脂組成物の押出成形に用いる成形機に特に制限は無く、通常の単軸あるいは2軸の押出機を使用することが可能であり、更に適当な構造の押出機を使用することにより、シート状押出成形品、フィルムあるいはパイプ等の異型押出成形品、または他の熱可塑性樹脂とを2層以上の多層構造で共押出成形してなる共押出成形品を成形することも可能である。また押出成形時の加工温度については特に制限はないが、加工性の観点から160〜240℃の範囲であることが好ましい。 Moreover, there is no restriction | limiting in particular in the molding machine used for extrusion molding of the said resin composition, It is possible to use a normal single-screw or a twin-screw extruder, and also by using an extruder of a suitable structure. It is also possible to form a sheet-like extrusion molded article, a profile extrusion molded article such as a film or a pipe, or a coextrusion molded article obtained by co-extrusion molding with another thermoplastic resin in a multilayer structure of two or more layers. . Moreover, there is no restriction | limiting in particular about the processing temperature at the time of extrusion molding, However, It is preferable that it is the range of 160-240 degreeC from a viewpoint of workability.

上記にて得られた建材用押出成形品は、例えば雨樋、窓枠、屋根材、壁材、床材、シート材等の各種建材用途に好適に使用することができる。 The extruded product for building materials obtained above can be suitably used for various building materials such as rain gutters, window frames, roof materials, wall materials, floor materials, sheet materials and the like.
