Because of this, the industrial design and innovation of environmentally friendly (enVironmenta丨friendly) has been widely used in various technical fields and industrial production industries, and it has become the development of material technology in the future. Golf has been popular all over the world. "In highly developed or developed countries, especially", the main consumables in this sport, the demand for a golf year is billions. At present, existing golf balls are mainly made of materials that are difficult to be naturally decomposed. The more the wind moves toward the wind, the more harmful it is to the global environment. Especially in the driving range or the official playing field, the more natural golfing environment is more popular with golf enthusiasts. For example, the most popular golf sports area is mainly seaside, lakeside and forest. Wait. However, this trend makes the golf ball after use very difficult to recycle or completely unrecyclable, and is largely discarded in wilderness, lakes, forests, etc., which not only destroys the environment for many years, but is also more likely to be eaten by animals and endanger life. In order to solve the damage caused by golf waste to the natural environment and animals 201249912, there are related manufacturers to make golf balls with hydrolyzable materials such as polyvinyl alcohol (PVA/PVOH), in order to solve the problem of environmental damage.

Please greatly reduce the harm to the environment. Please refer to the first figure, which is a first application example of the elastic material of the present invention, which is made of an elastic material of the invention and comprises a golf ball 10 of one layer construction, golf of the embodiment The ball comprises a body 11 which adjusts the ratio of the biodegradable plastic, the rubber and the compatibilizer to provide the desired hardness and elastic properties of the body 11 in an embodiment of the one-layer construction. 'The main body 11 can be a solid sphere. Please refer to the second figure, the golf ball manufacturing method can include the following steps: Start 91: According to hardness and elasticity requirements Select the appropriate biodegradable plastic, rubber, and compatibilizer types and proportions. Mixing 92: After selecting the appropriate biodegradable plastic, rubber, and compatibilizer types and ratios, 'put the materials in appropriate proportions. It is mixed into 201249912 a mixed elastic raw material, and further additives such as modifier, filler or toner can be added in the kneading step." Raw material curing 93: After mixing, the mixed elastic raw material is solidified to form a homogeneous elastic state in a solid state. The raw material, in this step, the homogeneous elastic raw material may be granulated or granulated, or plated by a press plate. Forming 94: The homogeneous elastic plastic material is heat-formed into a body 11 of a suitable shape, which may be formed by injection molding (a granulated homogeneous elastic material may be used) or hot press forming (a press plate, granulation or not may be used) The homogeneous elastic material of a specific shape is formed into various shapes. Among them, injection molding is suitable for homogeneous elastic raw materials with better fluidity after melting. For example, those with better fluidity (about 30% rubber content) are suitable for injection molding, and those with insufficient fluidity can be formed by hot pressing (about 15 〇/〇). The rubber content of the golf ball may be formed by hot pressing using the homogeneous elastic plastic material directly to form an integrally formed golf ball 10, and the design of the hot pressing die may be directly after the hot pressing. A plurality of recesses (for example, 336 recesses) are formed on the surface of the golf ball 10, thereby reducing wind resistance and improving the feeling of use. If a double-layer golf ball 10A' is to be produced as shown in the third figure, the package described below can be implemented. In step 95, the double-layer golf ball 1A is composed of a main body 11A and an outer layer 12 stacked one by one from the inside to the outside. Covering 95: After completing a main body 11A, one of different material types or ratios is selected. The elastic material is coated on the outside of the main body 11 to form an outer layer 12'. The main body 11 and the outer layer 12 having different hardness and elasticity are pressed together by a process such as hot pressing. The golf ball 10A of the layer. The golf ball 10 having a double layer is relatively softer and more elastic than the golf ball 10 of the single layer, so that it has a fast rotation speed and a speed of 201249912 degree. The ball is used. The outer layer 12 of the double-layered golf ball 1A is generally thinner than the main camera 11A. It is also possible to repeatedly coat the 95 steps to form a golf ball of two or more layers.
