【発明の属する技術分野】
本発明は、ポリプロピレン等のポリオレフィンをはじめとする熱可塑性樹脂の成形品の耐白化性の改良された組成物の製造方法に関する。さらに本発明は、耐熱性、剛性、靭性、ガスバリアー性を改良すると共に表面硬度にも優れた成形品に好適な組成物の製造方法に関する。
【0002】
【従来の技術】
通常、ポリオレフィン等の熱可塑性樹脂は必要以上の応力あるいは衝撃を加えた場合、光の波長以上のサイズでクレーズを発生し、白化する。具体的には熱可塑性樹脂を指などで折り曲げたり、延伸したり、破壊したりした場合、容易に白化する。
ポリプロピレン(PP)あるいはポリエチレン(PE)、ナイロン(NY)等にゴム成分を添加した系などではとくにその現象が顕著に現れる。
【0003】
さらに、ポリプロピレン等のポリオレフィンをはじめとする熱可塑成樹脂の成形品は、その表面の硬度が十分とはいえず、成形品とした後の2次加工において、硬質樹脂でコーティングしたり、電子線架橋などで表面処理することなどが従来から提案されている。しかし、熱可塑性樹脂の熱成形に際して同時に表面硬度を改良することは、成形工程の短縮と、成形コストの低下のため望まれている。
【0004】

The present invention relates to a method for producing a composition with improved whitening resistance of a molded article of a thermoplastic resin including polyolefin such as polypropylene. Furthermore, this invention relates to the manufacturing method of a composition suitable for the molded article which was excellent in surface hardness while improving heat resistance, rigidity, toughness, and gas barrier property.
[0002]
[Prior art]
Normally, when a stress or impact more than necessary is applied to a thermoplastic resin such as polyolefin, crazing occurs at a size greater than the wavelength of light and whitens. Specifically, when the thermoplastic resin is bent with a finger or the like, stretched, or broken, it easily whitens.
This phenomenon is particularly noticeable in systems such as polypropylene (PP), polyethylene (PE), nylon (NY), and other rubber components.

Furthermore, molded products of thermoplastic resins such as polyolefins such as polypropylene cannot be said to have sufficient surface hardness, and they can be coated with a hard resin in the secondary processing after forming the molded product, Conventionally, it has been proposed to perform surface treatment by crosslinking or the like. However, it is desirable to improve the surface hardness at the same time as thermoforming a thermoplastic resin because of shortening of the molding process and reduction of molding cost.

Molding conditions Cylinder temperature: 200 ° C, mold temperature: 40 ° C, cooling time: 20 seconds Shape of injection molded product Vertical X width X thickness (mm) 125X13X3.2
The physical properties of this injection molded product were measured. The results are shown in Table 1.
However, the measurement was based on the following method.
(1) Flexural modulus (FM) (MPa): A test piece having a thickness of 1/8 inch was prepared and measured according to ASTM C790 under conditions of 51 mm span and 20 mm / min bending speed.
(2) Izod (IZ) (J / m); A test piece (rear notch) having a thickness of 1/4 inch was prepared and measured at 23 ° C. in accordance with ASTM D256.
(3) Martens hardness (1 / mm): Create a test piece having a thickness of 1/8 inch, perform with a load of 5 grams, measure the width of the scratches a total of 5 times, and calculate the reciprocal of each, The average value was obtained.
(4) JIS A hardness: Measured according to JIS K6301 using a test piece having a thickness of 1/8 inch.
(5) Oxygen transmission coefficient (cc · mm / m 2 · d · MPa): Measured at 23 ° C. and humidity 0% RH using a film having a thickness of 500 μm in accordance with the JIS K7126B method.
(6) Dynamic hardness DH2 (mN / μm2); Shimadzu Corporation, using a microhardness meter, the indenter is a triangular pyramid indenter, and the indenter is inserted into the sample until the load reaches 9.8 mN at 1.42 mN / sec. After holding for 5 seconds, unloading,
The penetration amount after removing the load was D, the test load was P, and the indenter constant α = 3.8854, and the dynamic hardness DH2 = α (P / D2) was obtained.

The melt kneading temperature was as follows. Examples 1 to 6 and Comparative Example 1 are 170 ° C., Examples 7 and 2 are 170 ° C., Examples 8 and 3 are 230 ° C., and Example 9 is 170 ° C.
(7) Tensile test In accordance with ASTM D638, measurement was performed at 23 ° C. and a crosshead speed of 50 mm / min using an ASTM IV test piece.
[0021]
Moreover, the following was utilized for the thermoplastic resin.
NA-11 is the following compound.

Examples 10 to 13 and Comparative Examples 5 to 7
The thermoplastic resin produced by the present invention is excellent in whitening resistance even when stretched or bent, and can enhance the value of the product.
The whitening resistance was evaluated by stretching the tensile test specimen ASTMIV at a chuck speed of 50 mm / min until breaking, and visually evaluating the degree of whitening of the test specimen after measurement.
