Problems solved by technology

[0004] However, despite the above-mentioned advantages of polyurethane, since polyurethane is a polymer sensitive to temperature changes, changes in low and high temperature conditions caused by seasonal changes may change its physical properties
Therefore, even if you hit with the same strength, there will be a part of the number of spins and recovery characteristics that will change due to changes in the season or the surrounding environment.

Abstract

The present invention provides a resin composition for a golf ball cover, wherein, since the resin composition for the golf ball cover according to the present invention minimizes changes in physical properties due to temperature changes and improves restitution characteristics, the resin composition for the golf ball cover may reduce performance deviations of a golf ball due to seasonal temperature changes and may improve a spin rate of the golf ball.

Description

technical field [0001] The present invention relates to a resin composition for a golf ball cover. Background technique [0002] There has been research and development of a golf ball that allows a golfer to impart a large amount of spin to the ball at impact, is less prone to wear and has greater carry distance even after repeated hits. Generally, a golf ball consists of a core and a cover surrounding the core. In particular, the cover of a golf ball is a portion that is directly hit, and its hardness, abrasion resistance, and scuff resistance are important, and physical properties such as excellent hit recovery characteristics, flexibility, and softness are also required. [0003] Recently used materials for golf ball coverings include urethane cast by a casting method, in which urethane has excellent elasticity, provides a good hitting feeling at the time of hitting the ball and increases the number of spins of the golf ball, making the golf ball fly more Far. In addit...
