The present disclosure provides a resin composition for a golf ball cover. The resin composition includes a thermoplastic polyurethane resin including 55 to 70 parts by weight of a polyol, 30 to 40 parts by weight of an isocyanate, and 0.2 to 0.4 parts by weight of a polysiloxane. The polysiloxane includes at least one hydroxyl group or a carboxyl group in the terminal alkyl group. The polyol and the isocyanate constitute a silicone-free thermoplastic polyurethane resin, and the polysiloxane and the isocyanate constitute a thermoplastic polyurethane resin that includes silicone in the main chain, thereby improving the scuff resistance and slip property required for a golf ball cover.

Resin composition for golf ball cover

Golf ball

The present invention relates to a coating composition for covering golf balls. More particularly, the present invention relates to a matte coating composition mixed with a synthetic fatty acid resin derived from dehydrated castor oil. According to the present invention, a golf ball having a matte surface can realize a uniform and fine matte appearance and ensure a field of vision to enable high-precision hitting, faithfully express desired marks of various colors, characters and patterns applied thereto, and prevent surface yellowing caused by exposure to ultraviolet rays over a long period of time.

Coating composition for golf balls

An exhaust gas after-treatment device for a diesel engine is provided. The exhaust gas after-treatment device comprises an oxidation treatment unit having a diesel oxidation catalyst (DOC), an adsorption treatment unit having a diesel particulate filter (DPF), and a discharge unit for discharging exhaust gas that is filtration-treated through the oxidation treatment unit and the adsorption treatment unit, wherein the DOC of the oxidation treatment unit is provided with a baffle on the front thereof for even diffusion-introduction of exhaust gas.

Exhaust gas after-treatment device for diesel engine

A fitting portion structure of a device for post-processing exhaust gas in an agricultural operation vehicle is provided. The device is arranged in parallel to the lengthwise direction of an engine at the upper portion of an exhaust manifold of the engine, an exhaust gas inlet is coupled to the exhaust manifold or to a turbo charger and a flange pipe which are located at the lower portion of the exhaust gas inlet, and a fixing means is arranged between the engine and the device to support the load of the device. The fixing means includes a frontal bracket arranged between a cylinder head on the front side of the engine and a DPF canning of the device, and a rear bracket arranged between a cylinder head on the rear side of the engine and a flange coupling portion of the flange pipe.
