Description

  The present invention relates to a foaming ethylene-α-olefin copolymer, a foaming resin composition, and a foam.

Foams made of an ethylene-α-olefin copolymer are excellent in flexibility and heat insulating properties, and thus are used in various applications such as buffer materials and heat insulating materials. As a method for producing a foam made of such an ethylene resin, an ethylene resin and a thermally decomposable foaming agent are melt-mixed at a temperature at which the thermally decomposable foaming agent is not decomposed and molded into a sheet. A method is known in which ionizing radiation is applied to the sheet to crosslink the sheet, and then the sheet is heated to a temperature equal to or higher than the decomposition temperature of the thermally decomposable foaming agent.
As one of ethylene-α-olefin copolymers, a copolymer polymerized using a metallocene catalyst is known. An ethylene-α-olefin copolymer polymerized using a metallocene catalyst is excellent in mechanical strength such as impact strength and tensile strength. Therefore, when a foam having the same mechanical strength as that of a conventional foam is produced using the ethylene-α-olefin copolymer, a foam having a higher expansion ratio than that of the conventional product can be obtained. It is expected to be possible. However, an ethylene-α-olefin copolymer polymerized using a metallocene catalyst has a high extrusion load during extrusion and a low melt tension and swell ratio. Was demanded.

  In contrast, recently, a novel metallocene catalyst has been investigated, and a crosslinked foamed resin composition and a crosslinked foam using an ethylene-α-olefin copolymer polymerized by the catalyst and improved in molding processability are provided. Proposed.

(the unit of melt complex viscosity is Pa · sec. The unit of the angular frequency is rad / sec.), Based on the temperature-time superposition principle, for each melt complex viscosity-angular frequency curve at each temperature (T), The shift factor (a _T ) at each temperature (T) obtained when superposed on the melt complex viscosity-angular frequency curve of the coalescence is obtained, and each temperature (T) and the shift factor at each temperature ( _T ) are obtained. From (a _T ), a first-order approximate expression (formula (I) below) of [ln (a _T )] and [1 / (T + 273.16)] is calculated by the method of least squares. Next, Ea is obtained from the slope m of the linear expression and the following expression (II).
ln (a _T ) = m (1 / (T + 273.16)) + n (I)
Ea = | 0.008314 × m | (II)

  The melt complex viscosity-angular frequency curve is measured using a viscoelasticity measuring device (for example, Rheometrics Mechanical Spectrometer RMS-800 manufactured by Rheometrics), and usually geometry: parallel plate, plate diameter: 25 mm, plate interval: 1. It is performed under the conditions of 5 to 2 mm, strain: 5%, angular frequency: 0.1 to 100 rad / sec.

The winding speed is increased during the MT measurement, and the MT value at the time of fracture is expressed by the following empirical formula (2) with respect to the MFR.
MT = αexp (βMw) (2)
It is reported by the literature (D. Ancierno et al. Journal of Rheology, 29 (3), 323-334 (1985)). Also, the relational expression between Mw and MFR is empirically expressed by the formula (3)
Mn = A + Blog (MFR) (3)
Can be expressed in the literature (Mortimer et al. Journal of Applied Polymer Science, 8, 839-847 (1964), etc.). When these equations are combined, MT is empirically determined using MFR. C ・ MFR ^D (C and D are constants) (4)
It can be expressed by. Although C and D vary depending on the ratio of the transition metal compound described below, the values of C and D can be regarded as almost constant if the polymerization conditions other than the hydrogen concentration are substantially the same. In this example, the ethylene and 1-hexene concentrations are slightly different from one example to another, but the density is almost the same as around 920 kg / m ^3, so the polymerization conditions other than the hydrogen concentration can be said to be almost the same. Therefore, from the data in the examples, the transition metal compound (A): transition metal compound (B) = 12.5: 1 and the MT and MFR plots of the examples in which the polymerization conditions other than the hydrogen concentration were made almost constant. Using Microsoft Excel, fitting was performed using equation (4), and 30% of the C value obtained at the time of fitting was added to the C and D coefficient portions of the fitting result to obtain the right side. Significant figures were two decimal places. Similarly, the transition metal compound (A): transition metal compound (B) = 12.5: 1 and the MT and MFR plots of the examples in which the polymerization conditions other than the hydrogen concentration were made almost constant were similarly (4 ), And the left side was obtained by subtracting 30% of the absolute values of C and D obtained at the time of fitting from the C and D coefficient parts of the fitting result.

If the melt tension is too small, the expansion ratio may be reduced. The melt tension preferably satisfies the relational expression (1) ′ between MFR and MT, more preferably the relational expression (1) ″ between MFR and MT, and even more preferably (1) ′ ″. Relational expressions (1) ′, (1) ″, and (1) ′ ″ are obtained by adding and subtracting 30% of the value of C when the right and left sides of relational expression (1) are derived, respectively. It was derived in exactly the same way except that it was changed to 20%, 15% and 10%.

6.93 × MFR ^−0.59 <MT <9.34 × MFR ^−0.59 (1) ″
7.33 × MFR− ^0.59 <MT <8.94 × MFR− ^0.59 (1) ″ ′

The melt tension was obtained by extruding molten ethylene-α-olefin copolymer from an orifice having a diameter of 2.095 mm and a length of 8 mm at a temperature of 190 ° C. and an extrusion speed of 0.32 g / min. -The filamentous ethylene-α-olefin copolymer was cut from the start of the take-up at the tension when taking the α-olefin copolymer into a filament at a take-up rate of 6.3 (m / min) / min. It is the maximum tension until. In addition, the melt tension can be changed by, for example, the pressure of ethylene during polymerization in the production method described later. When the pressure of ethylene during polymerization is lowered, the melt tension of the ethylene-α-olefin copolymer is increased. Become. The melt tension can also be increased by carrying out prepolymerization under appropriate conditions.

Moreover, from a viewpoint of raising the mechanical strength of the foam obtained, Preferably it is 3.5 / 1000C or less, More preferably, it is 3.0 / 1000C or less, More preferably, it is 2.5 / 1000C or less. Further, the N _LCB can be changed in the production method described later, for example, depending on the concentration of the electron donating compound or the use ratio of the transition metal compound (A1) and the transition metal compound (A2). It can also be controlled by carrying out prepolymerization.

N _LCB has a carbon atom number of 5 or more, assuming that the total area of all peaks observed at 5 to 50 ppm is 1000 from a ¹³ C-NMR spectrum measured by a carbon nuclear magnetic resonance ( ¹³ C-NMR) method. It is obtained by determining the area of the peak derived from the methine carbon to which the branch is bonded. The peak derived from methine carbon to which a branch having 5 or more carbon atoms is bonded is around 38.2 ppm (Reference: Scientific Document “Macromolecules”, (USA), American Chemical Society, 1999, Vol. 32, p. 3817-3819 ). Since the position of the peak derived from methine carbon to which a branch having 5 or more carbon atoms is bonded may vary depending on the measuring device and the measuring conditions, the standard is usually measured for each measuring device and measuring conditions. decide. In the spectrum analysis, it is preferable to use a negative exponential function as the window function.

On the other hand, lnα (t) is a value calculated as the slope of lnα (t) between t _h seconds and t _h +0.5 seconds, where t _h is the time at which the rise starts from a constant value.
In the linear region until strain hardening occurs, σ ₁ (t) = σ _0.1 (t), and α (t) shows a constant value. When strain hardening occurs, σ ₁ (t) deviates from the linear region and becomes a non-linear region, and α (t) increases from a constant value.

  The measurement of the viscosity-time curve σ (t) of the molten resin is performed using a viscoelasticity measuring device (for example, ARES manufactured by TA Instruments). Note that the measurement is performed in a nitrogen atmosphere.

Here, k1 is the slope of lnα (t) between the time t between t _h +0.5 seconds and t _h +1.0 seconds, and k2 is between the time t between t _h seconds and t _h +0.5 seconds. The slope of lnα (t). That is, the elongational viscosity nonlinear index elongational viscosity nonlinear index ratio k1 / k2 is a large value when sufficient strain hardening is exhibited even in a high strain region, and a small value when strain hardening is insufficient in the high strain region. Become. Although the conventional ethylene-α-olefin copolymer has insufficient strain hardening in the high strain region, the more preferable ethylene-α-olefin copolymer in the present invention is surprisingly even in the high strain region. High strain hardening characteristics.
In the present invention, the reason for the extensional viscosity nonlinear index ratio is unknown, but the dependence of MFR is strong, and when the measured data is plotted to examine the tendency, the horizontal axis is ln (MFR), and the vertical axis is k1 /. It was found that the straight line is a very good approximation when k2. As for the relational expression of Expression (6), all data of the example plotted with the horizontal axis as MFR and the vertical axis as k1 / k2 are fitted with y = Aln (x) + B using Microsoft Excel. 20% of the value of the coefficient B obtained at the time of fitting is added to the coefficient B of the approximate expression with respect to the approximate expression k1 / k2 = 0.3465 × ln (MFR) +1.0531 obtained by The lower limit was derived by subtracting the upper limit. Equations (6) ′ and (6) ″ were derived in exactly the same manner as Equation (6) except that the 20% of the absolute value of B was changed to 15% and 10%, respectively.
