Abstract
The invention provides a composition for a color golf ball cover layer using a thermoplastic polyurethane resin and a method for manufacturing the color golf ball cover layer. The composition, according to the invention, for the color golf ball cover layer contains 1-10 parts by weight of a toning master batch, which is obtained through deployment of a white pigment, colored pigments and a heat stabilizer in a thermoplastic polyurethane resin and through extrusion molding, and 0.5-5 parts by weight of a lubricant relative to 100 parts by weight by the thermoplastic polyurethane resin. The pigments are taken as the master batches to perform deployment, so the pigments are easy to deploy, and injection molding can be performed; and an obtained color golf ball can improve visibility of the golf ball when golf athletics is performed, psychological stability based on personal color preference and an athletics force brought by the psychological stability can be achieved.
Description
technical field [0001] The present invention relates to a composition for a colored golf ball cover (golf ball cover, cover layer, outer layer) and a method for producing the colored golf ball cover. More specifically, a composition for a colored golf ball cover in which a plurality of pigments are blended as a masterbatch in a thermoplastic polyurethane (TPU) resin, and a method for producing the colored golf cover. Background technique [0002] In general, a golf ball with good performance should fly farther, and should have excellent spin rate (spin rate), control when hitting the iron. Common golf ball manufacturing companies use ionomer resin or thermosetting polyurethane as the composition of the golf ball cover. [0003] The above-mentioned ionomer resin has excellent durability and repulsion, and therefore, is most commonly used as a golf ball cover composition. In addition, it is relatively easy to mix color pigments, and golf ball covers of various colors can be ...
