Embodiment 1
[0064] Polybutene (melt flow rate is 0.62 g / 10 min, density is 0.9105 g / cm 3 ) And antioxidants, processing stabilizers, nucleating agents and open agents, wherein the main antioxidant is four [β- (3,5-di-tert-butyl-4-hydroxyphenyl) propionic acid] pentaerythritol ester, The addition amount is 1600 ppm; the complementary oxygen is three (2,4-di-tert-butylphenyl) phosphite, the addition amount is 3200 ppm; the processing stabilizer is calcium stearate, the amount of 500 ppm is added; the nucleating agent is 3790, the amount of addition is 900 ppm; the opening agent is an oleic acid amide, the amount is 1000 ppm (the above is based on the polybutenylene per gram). The above composition was added to the kneading machine, the cylinder temperature was 190 ° C, the screw rotational speed 40R / min. After the mixer extruded granulation, it was produced into a film product, and the product performance was shown in Table 1.
Embodiment 2
[0066] Polybutene (melt flow rate is 0.62 g / 10 min, density is 0.9105 g / cm 3 ) And antioxidants, processing stabilizers, nucleating agents and open their auxiliaries, wherein the main antioxidant is β- (3,5 di-tert-butyl-4-hydroxybenzene) propionate octadol ester, add The amount is 2400 ppm; the complementary oxygen is three (2,4-di-tert-butylphenyl) phosphite, the amount of addition is 2400 ppm; the processing stabilizer is zinc stearate, the addition is 400 ppm; the nucleating agent is 20e The amount of addition is 800 ppm; the opening agent is a mustard amide, the amount is 500 ppm (the above is based on polybutene per gram). The above composition was added to the mixer, the cylinder temperature was 195 ° C, and the screw speed was 50 R / min. After the mixer extruded granulation, it was produced into a film product, and the product performance was shown in Table 1.
Embodiment 3
