Practice golf ball core

Abstract

The invention discloses a practice golf ball core. The practice golf ball core comprises the following raw materials by weight: 100 parts of rubber, 26 parts of ethyl diamine, 38 parts of light calcium carbonate, 7 parts of zinc oxide, 3 parts of stearic acid, 0.8 part of water-like peroxide, 20 parts of ground starch and 10 parts of ultra-high molecular weight polyethylene. A preparation method for the practice golf ball core comprises the following concrete steps: adding the raw materials at 35 DEG C, working the raw materials until the temperature of the raw materials rise to 70 DEG C, pouring the raw materials out and rolling the raw materials on a roller six times; collecting the rolled raw materials together, dividing the rolled raw materials into six slices, carrying out standing in a standing chamber for 8 h and then carrying out strip cutting and hot press molding; and finally, carrying out sulfuration at 145 to 155 DEG C for 420 to 400 s, removing edges of the sulfurized ball core after completion of sulfuration, then carrying out standing until the ball core is cooled and successively carrying out grinding, cleaning and drying. The beat resistance of the practice golf ball core is improved by about 10% while the resilience of the practice golf ball core is increased by 5%; and the practice golf ball core is energy-saving and environment-friendly and has long service life.

Description

technical field [0001] The invention relates to a golf ball, in particular to a golf practice ball center. Background technique [0002] At present, the formula of the center of the golf practice ball is: rubber, ethylenediamine, light calcium carbonate, zinc oxide, stearic acid and aqueous peroxide, the impact resistance of the center made by this formula is still not enough, and The ball is thrown away directly after use, causing waste. Contents of the invention [0003] The object of the present invention is to provide an energy-saving and environmentally-friendly golf practice ball center with higher impact resistance, better elasticity, energy-saving and environmental protection, and long service life, so as to solve the problems raised in the above-mentioned background technology. [0004] To achieve the above object, the present invention provides the following technical solutions: [0005] A golf practice ball center, the raw materials in parts by weight include:...
