【発明の属する技術分野】
本発明は、建材用樹脂組成物に関し、詳しくは、オフィスビル、一般住居などの壁装材、パーティション、キャビネット、オフィス家具、天井、床材などに使用される塩化ビニル系の建材用樹脂組成物に関する。
【0002】
【従来の技術】
従来より、塩化ビニル系の建材用樹脂組成物は公知である。例えば、ゴム弾性を付与して釘打ちによる水漏れを防止する様に改良された組成物として、ポリ塩化ビニルに、加硫ゴム屑粉、不飽和ポリエステル樹脂、フタル酸系可塑剤を配合してなる組成物が提案されている(例えば特許文献1参照)。
【0003】
【特許文献1】
特開昭52−66554号公報
【0004】
ところで、情報技術の発達により、我々の身の回りには、多くの情報関連機器システムが機能している。これらの機器からは電磁波ノイズが発生しており、機器の誤作動、故障などのトラブルが多発している。現状の居住空間内では、これらの電磁波ノイズによるトラブルを解消する方策が不充分であり、この問題を解決する技術が待たれていた。
【0005】
【発明が解決しようとする課題】
本発明は、上記実情に鑑みなされたものであり、その目的は、電磁波ノイズを吸収し得る建材用樹脂組成物を提供することにある。
【0006】
【課題を解決するための手段】
すなわち、本発明の要旨は、塩化ビニル系樹脂に、少なくとも、可塑剤と平均粒径30〜0.01μmの黒鉛および/またはカーボンブラックを配合して成る建材用樹脂組成物であって、可塑剤の配合割合が塩化ビニル系樹脂と可塑剤の合計に対して5〜50重量%であり、黒鉛および/またはカーボンブラックの配合割合が組成物全体に対して5〜40重量%であることを特徴とする建材用樹脂組成物に存する。
【0007】
【発明の実施の形態】
以下、本発明を詳細に説明する。本発明の建材用樹脂組成物は、塩化ビニル系樹脂に可塑剤と黒鉛および/またはカーボンブラックを配合して成る。
【0008】
塩化ビニル系樹脂としては、塩化ビニルの単独重合体の他、塩化ビニルを主成分とする他の共重合可能な単量体との共重合体など、塩化ビニルを主な構成単位とする樹脂が挙げられる。共重合可能な単量体としては、例えば、エチレン、プロピレン、アクリロニトリル、酢酸ビニル、マレイン酸またはそのエステル、アクリル酸またはそのエステル、メタクリル酸またはそのエステル等が挙げられる。
【0009】
可塑剤としては、ジ−2−エチルヘキシルフタレート、ジヘキシルフタレート、ジイソノニルフタレート、ジブチルフタレート等のフタル酸エステル系可塑剤、ジオクチルアジペート、ジイソデシルアジペート、ジオクチルセバケート、ジブチルセバケート等の脂肪族二塩基酸エステル系可塑剤、トリクレジルフォスフェート、トリアリールフォスフェート等のリン酸エステル系可塑剤の他、ポリエステル系可塑剤、トリメリット酸エステル系可塑剤、エポキシ系可塑剤などが挙げられる。これらの可塑剤は2種以上を併用してもよい。可塑剤の配合割合は、塩化ビニル系樹脂と可塑剤の合計に対して5〜50重量%であり、好ましくは10〜40重量%である。可塑剤の配合割合が5重量%未満の場合は、得られる樹脂組成物が硬くなり過ぎるため、成形加工後に応力が加わった際に簡単に割れが生じる。また、50重量%を超える場合は、軟らかくなり過ぎて腰が無くなり、建材としての機能を発揮し得ない。
【0010】
黒鉛およびカーボンブラックの平均粒径は、30〜0.01μmであり、好ましくは20〜0.05μmである。平均粒径が30μmを超える場合は、塩化ビニル系樹脂への均一分散性が劣るため、得られる樹脂組成物の成形加工が難しくなる。また、平均粒径が0.01μm未満の場合は、保管時などに空気中の水分により凝集現象が起こり、塩化ビニル系樹脂への均一分散が出来なくなるため、得られる樹脂組成物の成形加工が難しくなる。なお、上記の平均粒径は、顕微鏡により1000個程度の粒子を観察測定し、それから算出した平均値を意味する。
【0011】
黒鉛および/またはカーボンブラックの配合量は、組成物全体に対して5〜40重量%であり、好ましくは7〜30重量%である。これらの配合量が5重量%未満の場合は、電磁波ノイズ吸収性の指標である比誘電率と誘電正接値が小さくなり、電磁波ノイズの吸収性が劣り、充分な効果を発揮し得ない。一方、配合量が40重量%を超える場合は、得られる樹脂組成物が硬くなり過ぎるため、成形加工後に応力が加わった際に簡単に割れが生じ、建材としての機能を発揮し得ない。
【0012】
本発明の建材用樹脂組成物には、必要に応じ、塩化ビニル系樹脂に通常添加される安定剤、難燃剤、ブロッキング防止剤、充填剤、分散剤、着色剤などを適宜添加してもよい。
【0013】
本発明の建材用樹脂組成物は、例えば、スーパーミキサー、バンバリーミキサー等で前記の各成分を混合し、カレンダーロール、押出機などにより、任意の厚さに成形加工され、各種用途の建材として使用される。
【0014】
【実施例】
以下、本発明を実施例により更に詳細に説明するが、本発明は、その要旨を超えない限り、以下の実施例に限定されるものではない。
【0015】
<評価試験方法>
(1)比誘電率および誘電正接:
(株)関東電子応用開発社製の空洞共振器摂動法誘電率測定装置を使用し、電磁波周波数2.0〜4.0ギガヘルツ(GHz)の比誘電率および誘電正接を測定した。充分な電磁波ノイズ吸収効果が得られるためには、比誘電率が5.0以上、誘電正接が0.05以上であることが必要である。
【0016】
(2)硬さ:
JIS K 6301 A型によるスプリング式硬度計で硬さを測定した。硬さが70未満であると軟らか過ぎて腰がなくなり、建材として機能しなくなる。また、硬さが95以上であると硬くなり過ぎて、折り曲げ等の応力が加わると割れが生じる。従って、建材用途における硬さの適正範囲は70〜94と考えられる。
【0017】
実施例1〜4及び比較例1〜5
スーパーミキサーにより、表1及び表2に示す配合物を5分間攪拌混合した後、表面温度が160℃のミルロールで7分間混練し、厚さ0.6mmのシートを作成した。なお、比較例5は、可塑剤量が少なく成形加工時に樹脂粘度が高くなり、樹脂の発熱温度が高くなるため、樹脂加工時の熱分解を防止する安定剤(エポキシ化大豆油、Ba−Zn系安定剤)を、他のものより増量した。
【0018】
上記のシートを4枚重ね、温度180℃、面圧1Kg/cm2 のプレス機で5分間加圧し、厚さ2mmのシートを得た。ただし、比較例1に示す配合は、黒鉛の平均粒径が小さ過ぎて粒子の凝集が発生し、比較例2に示す配合は、カーボンブラックの平均粒径が大き過ぎ、何れも、これらの粒子が均一に分散せず、評価に供するシートが得られなかった。評価試験の結果を表3及び表4に示す。
【0019】
【表1】
【0020】
【表2】
【0021】
【表3】
【0022】
【表4】
【0023】
実施例1〜4では比誘電率が5.0以上、誘電正接が0.05以上あり、2.0〜4.0GHzにおける電磁波ノイズの吸収に効果がある。また、建材用途として適性範囲(70〜94)の硬さである。
【0024】
一方、比較例3は、黒鉛の添加量が3重量%と少ないため、比誘電率、誘電正接共小さく、2.0〜4.0GHzにおける電磁波ノイズの吸収効果を充分に発揮しえない。比較例4は、カーボンブラックの添加量が43重量%と多いため、硬さが96と硬く、折り曲げ等の応力により簡単に割れてしまう。
【0025】
【発明の効果】
本発明によれば、パソコン等の情報関連機器から発生する電磁波ノイズの吸収効果に優れ、オフィスビル、一般住居などの壁層材、パーティション、キャビネット、オフィス家具、天井、床材などに好適な建材用樹脂組成物が提供される。[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a resin composition for building materials, and more particularly, to a resin composition for vinyl chloride-based building materials used for wall coverings of office buildings, general dwellings, etc., partitions, cabinets, office furniture, ceilings, flooring materials and the like. About.
[0002]
[Prior art]
BACKGROUND ART Conventionally, vinyl chloride-based resin compositions for building materials have been known. For example, as a composition improved to impart rubber elasticity and prevent water leakage due to nailing, blending polyvinyl chloride, vulcanized rubber dust, unsaturated polyester resin, and phthalate plasticizer The following composition has been proposed (for example, see Patent Document 1).
[0003]
[Patent Document 1]
JP-A-52-66554
By the way, due to the development of information technology, many information-related equipment systems are functioning around us. Electromagnetic noise is generated from these devices, and troubles such as malfunctions and failures of the devices occur frequently. In the current living space, measures for solving the problems caused by these electromagnetic noises are insufficient, and techniques for solving this problem have been awaited.
[0005]
[Problems to be solved by the invention]
The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a resin composition for building materials capable of absorbing electromagnetic wave noise.
[0006]
[Means for Solving the Problems]
That is, the gist of the present invention is a resin composition for building materials comprising a vinyl chloride resin and at least a plasticizer and graphite and / or carbon black having an average particle size of 30 to 0.01 μm. Is 5 to 50% by weight based on the total of the vinyl chloride resin and the plasticizer, and the compounding ratio of graphite and / or carbon black is 5 to 40% by weight based on the whole composition. And a resin composition for building materials.
[0007]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the present invention will be described in detail. The resin composition for building materials of the present invention is obtained by blending a plasticizer and graphite and / or carbon black with a vinyl chloride resin.
[0008]
Examples of the vinyl chloride resin include, in addition to a vinyl chloride homopolymer, a resin containing vinyl chloride as a main structural unit, such as a copolymer with another copolymerizable monomer having vinyl chloride as a main component. No. Examples of the copolymerizable monomer include ethylene, propylene, acrylonitrile, vinyl acetate, maleic acid or its ester, acrylic acid or its ester, methacrylic acid or its ester, and the like.
[0009]
Examples of the plasticizer include phthalate plasticizers such as di-2-ethylhexyl phthalate, dihexyl phthalate, diisononyl phthalate, and dibutyl phthalate; aliphatic dibasic esters such as dioctyl adipate, diisodecyl adipate, dioctyl sebacate, and dibutyl sebacate. Other examples include a phosphate plasticizer such as a plasticizer, tricresyl phosphate, and triaryl phosphate, as well as a polyester plasticizer, a trimellitate plasticizer, and an epoxy plasticizer. Two or more of these plasticizers may be used in combination. The mixing ratio of the plasticizer is 5 to 50% by weight, preferably 10 to 40% by weight, based on the total of the vinyl chloride resin and the plasticizer. When the compounding ratio of the plasticizer is less than 5% by weight, the obtained resin composition becomes too hard, so that cracks easily occur when stress is applied after molding. On the other hand, if it exceeds 50% by weight, it becomes too soft and loses its stiffness, failing to exhibit its function as a building material.
[0010]
The average particle size of graphite and carbon black is 30 to 0.01 μm, preferably 20 to 0.05 μm. When the average particle size exceeds 30 μm, the uniform dispersibility in the vinyl chloride resin is inferior, so that the molding process of the obtained resin composition becomes difficult. When the average particle size is less than 0.01 μm, agglomeration occurs due to moisture in the air during storage and the like, and uniform dispersion in the vinyl chloride resin cannot be performed. It becomes difficult. In addition, the said average particle diameter means the average value which observed and measured about 1000 particles with a microscope, and calculated from it.
[0011]
The compounding amount of graphite and / or carbon black is 5 to 40% by weight, preferably 7 to 30% by weight, based on the whole composition. When the amount of these components is less than 5% by weight, the relative permittivity and the dielectric loss tangent value, which are indicators of electromagnetic wave noise absorption, become small, electromagnetic wave noise absorption is poor, and no sufficient effect can be exhibited. On the other hand, if the compounding amount exceeds 40% by weight, the resulting resin composition becomes too hard, so that when a stress is applied after the molding process, the resin composition is easily cracked and cannot function as a building material.
[0012]
In the resin composition for building materials of the present invention, if necessary, stabilizers, flame retardants, anti-blocking agents, fillers, dispersants, coloring agents and the like which are usually added to vinyl chloride resins may be appropriately added. .
[0013]
The resin composition for building materials of the present invention is, for example, a mixture of the above components in a super mixer, a Banbury mixer, etc., is formed into a desired thickness by a calender roll, an extruder, etc., and is used as a building material for various applications. Is done.
[0014]
【Example】
Hereinafter, the present invention will be described in more detail with reference to examples, but the present invention is not limited to the following examples unless it exceeds the gist of the present invention.
[0015]
<Evaluation test method>
(1) Dielectric constant and dielectric loss tangent:
The relative permittivity and the dielectric loss tangent at an electromagnetic wave frequency of 2.0 to 4.0 gigahertz (GHz) were measured using a cavity resonator perturbation method dielectric constant measuring device manufactured by Kanto Electronics Application Development Co., Ltd. In order to obtain a sufficient electromagnetic wave noise absorption effect, it is necessary that the relative dielectric constant is 5.0 or more and the dielectric loss tangent is 0.05 or more.
[0016]
(2) Hardness:
The hardness was measured with a spring-type hardness tester according to JIS K6301 A type. If the hardness is less than 70, it is too soft and loses its stiffness and does not function as a building material. On the other hand, if the hardness is 95 or more, it becomes too hard, and cracks occur when stress such as bending is applied. Therefore, it is considered that the appropriate range of the hardness in the building material application is 70 to 94.
[0017]
Examples 1-4 and Comparative Examples 1-5
The blends shown in Tables 1 and 2 were stirred and mixed by a super mixer for 5 minutes, and kneaded with a mill roll having a surface temperature of 160 ° C. for 7 minutes to form a sheet having a thickness of 0.6 mm. In Comparative Example 5, since the amount of the plasticizer was small and the resin viscosity was high during molding and the heat generation temperature of the resin was high, stabilizers for preventing thermal decomposition during resin processing (epoxidized soybean oil, Ba-Zn System stabilizer) was increased over the others.
[0018]
Four of the above sheets are stacked, at a temperature of 180 ° C. and a surface pressure of 1 kg / cm 2. For 5 minutes to obtain a sheet having a thickness of 2 mm. However, in the composition shown in Comparative Example 1, the average particle diameter of graphite was too small, causing aggregation of the particles, and in the composition shown in Comparative Example 2, the average particle diameter of carbon black was too large. Was not uniformly dispersed, and a sheet for evaluation could not be obtained. Tables 3 and 4 show the results of the evaluation test.
[0019]
[Table 1]
[0020]
[Table 2]
[0021]
[Table 3]
[0022]
[Table 4]
[0023]
In Examples 1 to 4, the relative dielectric constant is 5.0 or more and the dielectric loss tangent is 0.05 or more, which is effective in absorbing electromagnetic noise at 2.0 to 4.0 GHz. In addition, the hardness is in a suitable range (70 to 94) for use as a building material.
[0024]
On the other hand, in Comparative Example 3, since the amount of graphite added was as small as 3% by weight, the relative dielectric constant and the dielectric loss tangent were both small, and the effect of absorbing electromagnetic noise at 2.0 to 4.0 GHz could not be sufficiently exhibited. In Comparative Example 4, since the added amount of carbon black was as large as 43% by weight, the hardness was as high as 96 and easily broken by stress such as bending.
[0025]
