The case of the bowling hole providing apparatus 60 includes 30 to 69.8 wt% of polypropylene, 20 to 35 wt% of inorganic filler, 10 to 25 wt% of rubber, 0.1 to 5 wt% of compatibilizer and 0.1 to 5 wt% of scratch resistance And has a DL value of 0.2 or less by the Erichsen method, a flexural modulus of 1000 to 2100 MPa, and an Izod impact strength of 16 to 40 KJ / m < 2 >. The polypropylene is preferably block copolypropylene, and may further comprise homopolypropylene or random polypropylene. The block copolypropylene preferably has a flexural modulus (FM) of 1000 to 2100 MPa and a room temperature Izod impact strength of 16 to 40 KJ / m 2, which is excellent in rigidity and improves impact properties .

The homopolypropylene preferably has a flexural modulus of 1270 to 2350 MPa and an Izod impact strength of 2 to 6 KJ / m 2 at room temperature, and exhibits an excellent stiffness although it lacks impact properties as compared with block copolypropylene. The random polypropylene preferably has a bending modulus of elasticity of 680 to 980 MPa and an Izod impact strength of 2 to 40 KJ / m 2 at room temperature. The random polypropylene has a stiffness lower than that of the block copolypropylene, but has excellent impact properties.

The content of the inorganic filler is preferably 20 to 35 wt%. If the content of the inorganic filler is less than 20 wt%, the flexural modulus is lowered. If the content of the inorganic filler is more than 35 wt%, the impact resistance may be lowered. The inorganic filler is preferably at least one selected from the group consisting of talc, glass fiber, mica, calcium carbonate, wollastonite, barium sulfate, clay and magnesium sulfate whisker, and calcium sulfate whisker.

When the content of the rubber is less than 10 wt%, the impact resistance is lowered. When the content of the rubber is more than 25 wt%, the flexural elasticity may be lowered. have. The rubber is preferably at least one selected from ethylene octene rubber (EOR), ethylene butene rubber (EBR), ethylene propylene rubber (EPR), and SEBS.

If the content of the compatibilizing agent is less than 0.1 wt%, sufficient scratch resistance is not exhibited. If the amount of the compatibilizing agent is more than 5 wt%, the flexural modulus and impact resistance There is a problem of deterioration.

The compatibilizing agent may contain 0.1 to 10 wt% of maleic acid or maleic anhydride, 99.9 to 90 wt% of polypropylene and / or polyethylene.

The scratch resistant material is preferably polydimethylsiloxane having a content of 0.1 to 5 wt%. If the content is less than 0.1 wt%, the scratch resistance is insufficient, and when the content is more than 5 wt%, the flexural modulus may decrease.

If the melt index is less than 0.2 g / 10 min (ASTM D1238, 2.16 kg, 230 ° C), there is a high possibility of occurrence of defects such as gel. If the melt index exceeds 150 g / 10 min (ASTM D1238, 2.16 kg, 230 ° C) And the impact resistance is deteriorated.

The polyolefin resin composition is preferably a composite resin composition having a melt index of 3 to 40 g / 10 min (ASTM D1238, 2.16 kg, 230 DEG C), more preferably 7 to 35 g / 10 min (ASTM D1238, 2.16 kg, 230 [deg.] C). If the melt index is less than 3 g / 10 min (ASTM D1238, 2.16 kg, 230 ° C), there is a high possibility of appearance failure at the time of injection. If the melt index exceeds 40 g / 10 min (ASTM D1238, 2.16 kg, 230 ° C) The injection pressure is not normally applied to the molded article, and defects such as sinks and burrs may occur in the molded article.
