Description
本発明は、樹脂の２成分混合薬液による飽和膨潤量を予測する方法に関する。 The present invention relates to a method for predicting the saturation swelling amount of a resin two-component mixed chemical.
樹脂の１成分薬液による飽和膨潤量の予測については、Floryの著書（非特許文献１）に記されているが、２成分混合薬液における飽和膨潤量の予測は殆ど行われてはいない。
飽和膨潤量は、耐薬品性試験の必須項目であり、樹脂部品の製品設計において極めて重要である。特に、結晶性樹脂は耐薬品性が求められる箇所に多く用いられることから、結晶性樹脂の飽和膨潤量が必要とされる場合が多い。２成分混合薬液による飽和膨潤量は、単純に、それぞれの薬液１成分での飽和膨潤量にそれぞれの混合比を乗じて合算した値で推定しようとしても、実際の飽和膨潤量から著しく外れ、どの混合比の場合に飽和膨潤量が最大になるかを予測することはできない。そのため、実際に混合比の異なる混合薬液で浸漬試験を繰り返し実施する必要があり、多大の時間と手間を必要とすることから、効率的な予測手段が求められている。 The saturation swelling amount is an essential item for chemical resistance tests, and is extremely important in the product design of resin parts. In particular, since a crystalline resin is often used in a place where chemical resistance is required, a saturation swelling amount of the crystalline resin is often required. The amount of saturation swelling due to a two-component chemical solution is simply different from the actual saturation swelling amount even if it is estimated by simply multiplying the saturation swelling amount of each chemical component by the mixing ratio. In the case of the mixing ratio, it cannot be predicted whether the saturation swelling amount will be maximized. Therefore, it is necessary to repeatedly perform the immersion test with mixed chemical solutions having different mixing ratios, and a great amount of time and labor are required, so an efficient prediction means is required.
樹脂を任意比率で混合された２成分からなる混合薬液に浸漬したときの飽和膨潤量は、式(1),(2),(3)から計算的に求めることができる。
また、結晶性樹脂においては、結合点間のモノマー単位数を、ラメラ晶に挟まれた非晶部の平均厚みを結晶格子における分子鎖軸方向でのモノマー単位の長さで除したものとすることにより、結合点となる主鎖分岐点が殆ど無いかもしくは僅かな樹脂においても計算式を応用することができる。
The saturated swelling amount when the resin is immersed in a mixed chemical solution composed of two components mixed at an arbitrary ratio can be calculated from equations (1), (2), and (3).
In the crystalline resin, the number of monomer units between bonding points is obtained by dividing the average thickness of the amorphous part sandwiched between lamella crystals by the length of the monomer unit in the molecular chain axis direction in the crystal lattice. Therefore, the calculation formula can be applied even to a resin having few or few main chain branch points as bonding points.
１成分薬液による飽和膨潤量の式を拡張することで導いた、次の式(1),(2),(3)を用いることにより、２成分混合薬液による飽和膨潤量を計算で求めることができる。ここで、飽和膨潤量とは、薬液に浸漬した樹脂へ浸透した薬液の飽和重量のことであり、浸漬前の樹脂重量に対して百分率で表すことができる。
３成分以上の混合薬液においても、それぞれの薬液１成分での飽和膨潤量が１番多い成分と２番目に多い成分に対して本発明を実施することにより、近似的に飽和膨潤量を予測することができる。
By using the following formulas (1), (2), and (3) derived by expanding the formula for the amount of saturated swelling due to a one-component chemical, the amount of saturation swelling due to a two-component mixed chemical can be calculated. it can. Here, the saturated swelling amount refers to a saturated weight of the chemical liquid has penetrated into the resin soaked in the chemical, it is table Succoth a percentage relative to the resin weight before immersion.
Even in a mixed chemical solution of three or more components, the saturated swelling amount is approximately predicted by carrying out the present invention for the component having the largest saturated swelling amount and the second largest component in each chemical solution component. be able to.
ここで、ν1，ν2，ν3は膨潤した樹脂における体積分率を表し、
ν1は混合薬液の第一成分の飽和膨潤体積分率、
ν2は混合薬液の第二成分の飽和膨潤体積分率、
ν3は樹脂の飽和膨潤体積分率である。

χ12は混合薬液の第一成分と第二成分との相互作用パラメータ、
χ13は混合薬液の第一成分と樹脂との相互作用パラメータ、
χ23は混合薬液の第二成分と樹脂との相互作用パラメータである。
ｎは結合点間のモノマー単位数である。
ｕ1は混合薬液における第一成分の体積分率である。
Here, ν 1 , ν 2 , and ν 3 represent volume fractions in the swollen resin,
ν 1 is the saturation swelling volume fraction of the first component of the mixed chemical solution,
ν 2 is the saturation swelling volume fraction of the second component of the mixed chemical solution,
ν 3 is the saturated swelling volume fraction of the resin.
χ 12 , χ 13 , χ 23 represent Flory-Huggins interaction parameters,
χ 12 is the interaction parameter between the first and second components of the mixed drug solution,
χ 13 is the interaction parameter between the first component of the mixed chemical and the resin,
χ 23 is an interaction parameter between the second component of the mixed chemical solution and the resin.
n is the number of monomer units between the bonding points.
u 1 is the volume fraction of the first component in the mixed chemical solution.
また、χ13及びχ23は、樹脂を第一成分だけの薬液及び第二成分だけの薬液にそれぞれ浸漬したときの飽和膨潤量を実際に測定することで、式(4)及び(5)からそれぞれ計算的に求めることができる。 Further, χ 13 and χ 23 are obtained from the equations (4) and (5) by actually measuring the saturation swelling amount when the resin is immersed in the chemical solution containing only the first component and the chemical solution containing only the second component, respectively. Each can be calculated computationally.
χ12は蒸気圧測定から求めることができる。また、これらの値は既に文献に示されている値を用いてもかまわない。
また、樹脂を第一成分だけの薬液及び第二成分だけの薬液にそれぞれ浸漬したときの飽和膨潤量に加えて、任意のある一つの混合比率ｕ1で混合した二成分混合薬液に浸漬したときの飽和膨潤量を実測することで、式(4)及び(5)からそれぞれ求めたχ13及びχ23の値を用いて、式(1)、(2)、(3)からχ12を計算的に求めることができる。
χ 12 can be obtained from vapor pressure measurement. Also, these values may be values already shown in the literature.
Moreover, in addition to the saturated swelling amount when the resin is immersed in the chemical solution of only the first component and the chemical solution of only the second component, when the resin is immersed in a two-component mixed chemical solution mixed at any one mixing ratio u 1 Using the values of χ 13 and χ 23 obtained from equations (4) and (5), respectively, calculate χ 12 from equations (1), (2), and (3) Can be obtained.
結晶性樹脂は結晶部と非晶部の積層構造から成るが、結晶部を形成するラメラ晶は相互にタイモレキュールで結ばれており、ラメラ晶に挟まれた部分（タイモレキュールを含む）が非晶部である。そこで、結晶部を、架橋構造を持つ非晶性樹脂における高分子の結合点と同等とみなすことで、結晶性樹脂についても、結合点間のモノマー単位数ｎを決めることができ、飽和膨潤量を予測することができる。 The crystalline resin is composed of a laminated structure of crystal and amorphous parts, but the lamellar crystals that form the crystal part are connected to each other by thyme liqueur, and the part sandwiched between lamella crystals (including thymolecule) Is an amorphous part. Therefore, by regarding the crystal part to be equivalent to the bonding point of the polymer in the amorphous resin having a cross-linked structure, the number n of monomer units between the bonding points can be determined for the crystalline resin, and the saturation swelling amount Can be predicted.
結晶性樹脂においては、樹脂の非晶部のみが２成分の薬液によって膨潤するので、非晶部の割合を求める必要がある。例えば、密度法で結晶化度を測定することで、非晶部の割合を求めることができる。
ラメラ晶と非晶部で形成される積層構造における非晶部の平均厚みは、例えば小角Ｘ線散乱から求めることができる。
ほとんどの樹脂の結晶構造は解析され、文献に結晶格子の長さとモノマー数が示されており、分子鎖軸方向でのモノマー単位の長さを知ることができる。
非晶部の厚みを結晶格子における分子鎖軸方向でのモノマー単位の長さで除することにより、両端が結晶部に組み込まれた非晶部中の部分鎖のモノマー単位数ｎを決めることができる。
In the crystalline resin, only the amorphous part of the resin is swollen by the two-component chemical solution, so it is necessary to determine the ratio of the amorphous part. For example, the ratio of the amorphous part can be obtained by measuring the crystallinity by the density method.
The average thickness of the amorphous part in the laminated structure formed by the lamellar crystal and the amorphous part can be obtained from small angle X-ray scattering, for example.
The crystal structure of most resins has been analyzed, and the literature shows the length of the crystal lattice and the number of monomers, so that the length of the monomer unit in the molecular chain axis direction can be known.
By dividing the thickness of the amorphous part by the length of the monomer unit in the molecular chain axis direction in the crystal lattice, the number n of monomer units of the partial chain in the amorphous part in which both ends are incorporated in the crystal part can be determined. it can.
上述のパラメータを用いて、樹脂の非晶部における各成分の体積分率を式(1),(2),(3)から計算的に求めることにより、２成分からなる混合薬液に浸漬したときの飽和膨潤量が求まる。 When the volume fraction of each component in the amorphous part of the resin is calculated from the equations (1), (2), and (3) using the above parameters, and when immersed in a mixed chemical solution consisting of two components Is obtained.
