Definitions
- the present invention relates to a thermoplastic acrylic resin composition containing glass having a specific average particle diameter, and a molded body obtained by molding the thermoplastic acrylic resin composition.
- a glass material is used for the top sheet member of the solar cell.
- the glass topsheet member has good dimensional stability and flame retardancy, but there is a limit to weight reduction, and the solar cell module may be damaged when subjected to an impact. For this reason, replacement of a conventional glass topsheet member with a topsheet member made of a composite material using resin as a matrix material has been studied. When the top sheet member is replaced with a composite material, it is necessary to maintain the translucency of the composite material at the same level as that of the matrix resin in order to maintain the photoelectric conversion efficiency of the solar cell. Moreover, when using a composite material as a solar cell top sheet, it is necessary to heat laminate together with a top sheet, a sealing material, and a photovoltaic cell.
- Patent Document 1 proposes a method of dispersing glass fibers and fine particles having a refractive index difference of 0.01 or less in a transparent resin.
- a cured resin is used as the transparent resin and a thick molded body is produced, the glass material settles due to the specific gravity difference between the resin and the glass material in the composite before curing, and the cured In the later material, it is difficult to make the glass exist uniformly.
- Patent Document 2 proposes a method of dispersing flaky glass having an average particle diameter of 5 to 50 ⁇ m in a thermoplastic resin. However, since the glass used in this method has a small average particle size, the resulting molded article has insufficient translucency.
- Patent Document 3 proposes a method of dispersing glass beads having an average particle diameter of 1 to 10 ⁇ m in a thermoplastic resin. However, since the glass used in this method has a small average particle size and a spherical shape, multiple scattering is likely to occur in the resulting molded body, and the translucency may be lowered.
- Patent Document 4 discloses a composition in which glass flakes and mica using a rubber-reinforced polystyrene resin as a matrix are dispersed. However, since rubber is dispersed in the matrix, thermal expansion is large and rigidity is also lowered. Therefore, it is not sufficient as a top sheet for a solar cell. Further, in the material system disclosed in the example of Patent Document 4, the total light transmittance is about 70% at the maximum, and the translucency is not sufficient. Further, Patent Document 5 proposes a glass flake or glass fiber and a composite material having a refractive index difference of 0.015 or less between an aromatic polycarbonate and an aromatic polycarbonate resin. The rigidity and transparency are sufficient, but the weather resistance is not sufficient because aromatic polycarbonate is used as the matrix material.
- An object of the present invention is to provide a thermoplastic acrylic resin composition that is light-transmitting, reduced in warpage due to temperature change, and further excellent in weather resistance.
- the inventors of the present invention have incorporated a glass having a specific refractive index difference with respect to a matrix resin made of a thermoplastic acrylic resin with a specific average particle diameter into the thermoplastic acrylic resin, thereby translucent. It has been found that the occurrence of warpage due to temperature change is reduced, and further, a thermoplastic acrylic resin composition having excellent weather resistance can be obtained. That is, the present invention contains 0.1 to 50 parts by mass of glass (B) with respect to 100 parts by mass of thermoplastic acrylic resin (A), and the refractive index difference between thermoplastic acrylic resin (A) and glass (B).
- thermoplastic resin composition having an absolute value of 0.08 or less and an average particle size of glass (B) of 100 to 2,000 ⁇ m, and a softening temperature measured according to ASTM D648 is 80 ° C. or more
- this invention is a molded object obtained by shape
- this invention is a top sheet member of the solar cell whose YI value (yellowness degree) after the weather resistance test using the said molded object is 20 or less. Furthermore, this invention is a solar cell module using the said molded object.
- thermoplastic acrylic resin composition of the present invention has a light-transmitting property, the occurrence of warpage due to temperature change is reduced, and gives a molded article having excellent weather resistance.
- the molded body of the present invention is suitable as a top sheet member of a solar cell because it is translucent and the occurrence of warpage due to temperature change is reduced, and it is excellent in weather resistance.
- thermoplastic acrylic resin (A) used in the present invention is not particularly limited as long as it is a transparent thermoplastic acrylic resin.
- examples of the thermoplastic acrylic resin (A) include an acrylic resin and an MS resin copolymerized with styrene. These may be used alone or in combination of two or more. In these, since it is easy to adjust the absolute value of a refractive index difference with glass (B) to 0.08 or less, acrylic resin and MS resin are preferable and acrylic resin is more preferable.
- the acrylic resin is a known acrylic resin and is obtained by polymerizing (meth) acrylic acid ester.
- (meth) acrylic acid esters include methyl (meth) acrylate, ethyl (meth) acrylate, butyl (meth) acrylate, cyclohexyl (meth) acrylate, phenyl (meth) acrylate, and (meth) acrylic.
- examples include benzyl acid, 2-ethylhexyl (meth) acrylate, 2-hydroxyethyl (meth) acrylate, and (meth) acrylic acid. These may be used alone or in combination of two or more. Of these, methyl (meth) acrylate is preferred.
- the acrylic resin is preferably a resin containing 10 to 100% by mass of a methyl methacrylate unit because of good light transmittance, heat resistance, mechanical properties, moldability, and weather resistance.
- a resin containing 50 to 100% by mass of methyl methacrylate units is more preferable.
- Resins containing 10% by mass or more of methyl methacrylate units are 10 to 100% by mass of methyl methacrylate units and 0 to 90% by mass of other monomer units from the viewpoint of ensuring excellent optical properties and light resistance.
- It is preferably composed of 50 to 100% by mass of methyl methacrylate units, more preferably 0 to 50% by mass of other monomer units, and 70 to 100% by mass of methyl methacrylate units, More preferably, it is composed of 0 to 30% by mass of a monomer unit.
- Examples of other monomers that are raw materials constituting other monomer units include, for example, methyl acrylate, ethyl acrylate, butyl acrylate, cyclohexyl acrylate, phenyl acrylate, benzyl acrylate, 2-acrylate Acrylic acid esters such as ethylhexyl; Methacrylic acid esters such as ethyl methacrylate, butyl methacrylate, cyclohexyl methacrylate, phenyl methacrylate, benzyl methacrylate; Vinyl acetate; Styrene, p-methylstyrene, ⁇ -methylstyrene, vinylnaphthalene, etc.
- Aromatic vinyl monomers such as acrylonitrile and methacrylonitrile; ⁇ , ⁇ -unsaturated carboxylic acids such as acrylic acid, methacrylic acid, and crotonic acid; N-ethylmaleimide, N-cyclohexylmaleimide Maleimide compounds such as And the like. These may be used alone or in combination of two or more.
- the molecular weight of the thermoplastic acrylic resin (A) is preferably from 50,000 to 200,000, and preferably from 60,000 to 150,000, as measured by GPC in the case of a molding material to be molded by heating and melting.

Abstract
Description
本願は、2011年1月7日に、日本に出願された特願2011-001906号に基づき優先権を主張し、その内容をここに援用する。
トップシート部材を複合材料に置き換える場合、太陽電池の光電変換効率を保持するために、複合材料の透光性をマトリクスの樹脂と同程度に保つことが必要である。また、複合材料を太陽電池トップシートとして使用する場合には、トップシート、封止材、太陽電池セルとあわせて熱ラミネートを行う必要がある。しかし、ラミネート時に150℃程度の温度が加わるため、熱膨張の低減とトップシートの剛性確保が必要である。これらの特性が低い場合には、ラミネート時に反りや太陽電池セルのわれなどが発生してしまうため、好ましくない。
例えば、特許文献1では、透明樹脂中に屈折率差が0.01以下の屈折率差を有するガラス繊維や微粒子を分散させる方法が提案されている。しかしながら、透明樹脂として硬化樹脂を使用しており、厚みのある成形体を作製する際には、硬化前の複合化において、樹脂とガラス材料との比重差によってガラス材料が沈降してしまい、硬化後の材料において、ガラスを均一に存在させることが困難である。特に、微粒子やフレーク状のガラス材料を使用して、ガラス材料が均一に分散した厚みのある成形体を作製することは困難であった。
また、特許文献2では、熱可塑性樹脂中に平均粒径5~50μmのフレーク状ガラスを分散させる方法が提案されている。しかしながら、この方法で用いているガラスは平均粒径が小さいため、得られる成形体の透光性が充分ではない。
また、特許文献3では、熱可塑性樹脂中に平均粒径1~10μmのガラスビーズを分散させる方法が提案されている。しかしながら、この方法で用いているガラスは平均粒径が小さく、球状であるため、得られる成形体内で多重散乱が生じ易く、透光性が低下するおそれがある。
また、特許文献4では、ゴム強化ポリスチレン樹脂をマトリクスとしたガラスフレークやマイカを分散させた組成物が開示されているが、マトリクスにゴムが分散されているため、熱膨張が大きく、剛性も低下してしまい、太陽電池用トップシートとしては、十分でない。また、特許文献4の実施例で開示されている材料系では、全光線透過率が最大でも70%程度であり、透光性も十分でない。
また、特許文献5では、芳香族ポリカーボネートと芳香族ポリカーボネート樹脂との屈折率差が0.015以下のガラスフレークもしくはガラス繊維と複合材料が提案されている。剛性や透明性は十分だが、マトリクス材料として芳香族ポリカーボネートが使用されているため、耐候性が十分でない。
即ち本発明は、熱可塑性アクリル樹脂(A)100質量部に対してガラス(B)0.1~50質量部を含有し、熱可塑性アクリル樹脂(A)とガラス(B)の屈折率差の絶対値が0.08以下であり、ガラス(B)の平均粒径が100~2,000μmである熱可塑性樹アクリル脂組成物であって、ASTM D648に準じて測定した軟化温度が80℃以上である、請求項1記載の熱可塑性アクリル樹脂組成物である。ガラス(B)はアスペクト比が15以上であるフレーク状が好ましい。また本発明は、前記熱可塑性アクリル樹脂組成物を成形して得られる成形体である。
更に本発明は、前記成形体を用いた耐候性試験後のYI値(黄色度)が20以下である太陽電池のトップシート部材である。
さらに本発明は、前記成形体を用いた太陽電池モジュールである。
本発明の成形体は、透光性、温度変化による反りの発生が低減され、さらに、耐候性に優れることから、太陽電池のトップシート部材として好適である。
熱可塑性アクリル樹脂(A)としては、例えば、アクリル系樹脂、スチレンが共重合されたMS樹脂が挙げられる。これらは、1種を単独で用いてもよく2種以上を併用してもよい。
これらの中では、ガラス(B)との屈折率差の絶対値を0.08以下に調整し易いことから、アクリル系樹脂、MS樹脂が好ましく、アクリル系樹脂がより好ましい。
(メタ)アクリル酸エステルとしては、例えば、(メタ)アクリル酸メチル、(メタ)アクリル酸エチル、(メタ)アクリル酸ブチル、(メタ)アクリル酸シクロヘキシル、(メタ)アクリル酸フェニル、(メタ)アクリル酸ベンジル、(メタ)アクリル酸2-エチルヘキシル、(メタ)アクリル酸2-ヒドロキシエチル、(メタ)アクリル酸が挙げられる。これらは、1種を単独で用いてもよく2種以上を併用してもよい。
これらの中では、(メタ)アクリル酸メチルが好ましい。
メタクリル酸メチル単位を10質量%以上含有する樹脂は、その優れた光学特性及び耐光性を確保する観点から、メタクリル酸メチル単位10~100質量%、他の単量体単位0~90質量%で構成されることが好ましく、メタクリル酸メチル単位50~100質量%、他の単量体単位0~50質量%で構成されることがより好ましく、メタクリル酸メチル単位70~100質量%、他の単量体単位0~30質量%で構成されることが更に好ましい。
これらは、1種を単独で用いてもよく2種以上を併用してもよい。
熱可塑性アクリル樹脂(A)の質量平均分子量が5万以上であれば成形体の強度や耐久性が向上し、20万以下であれば流動性等の成形時の加工性が向上する。
ガラス(B)の平均粒径が100μm以上であれば成形体の透光性が良好となり、2,000μm以下であれば成形体の成形性が良好となる。
ガラス(B)のアスペクト比が15以上であれば成形体の透光性が良好となり、1,000以下であれば成形体の成形性が向上し、マトリクス樹脂中での均一分散が困難とならない。
アスペクト比は、上記平均粒径の値をガラス(B)の平均厚さの値で除することにより求めた。ガラス(B)の平均厚さは、ハイロックス社製 デジタルマイクロスコープ KH-3000によりガラス(B)30個の測定を行い、その単純平均により求めた。
ガラス(B)は、市販品として、日本板硝子社製フレーク状ガラス「ガラスフレーク」等を用いることができる。
熱可塑性アクリル樹脂(A)100質量部に対してガラス(B)の含有量が0.1質量部以上であれば成形体の透光性が良好となり、50質量部以下であれば成形時の加工性が低下しない。
また、熱可塑性アクリル樹脂組成物には、必要に応じて、公知の安定剤、添加剤等を添加してもよい。
押出成形により板状、フィルム状の成形体を得るには、Tダイ等の押出機を用いて押出した溶融樹脂を、冷却ロールで冷却しながら引取る方法が挙げられる。
尚、実施例中の「部」及び「%」は、それぞれ「質量部」及び「質量%」を示す。
ヘイズメーター(NDH2000:日本電色工業社製)を用い、D65光源にて、耐候性試験前後の試験片の全光線透過率(Tt)を測定した。本発明では、Ttを透光性の指標として用いる。

(d)平均厚み測定
ガラスフィラー(B)の平均厚みは、ハイロックス社製 デジタルマイクロスコープ KH-3000を用い、ガラスフィラー(B)30個の測定を行い、その単純平均により求めた。
