General amateur m golf balls are more like two-piece round golf balls that can achieve a long flying distance and two Η golf balls have recently been exclusively on the market. The invention is to solve the problem that the traditional wire-wound golf ball can only achieve a relatively short flying distance and the main purpose of the present invention is to provide a wire-wound golf ball with a good hitting j and equal to two pieces. The long flight distance of the golf ball can be achieved. The huge and other advantages and advantages of the wire-wound golf ball of the present invention are described in the following and refer to FIG. 5. FIG. 0 will become apparent to those skilled in the art Brief description of the formula (please read the precautions on the back before filling this page) This paper size is applicable to the Chinese National Standard (CNS) A4 Grid (210X: mmm) A7 B7 V. Description of the invention (4) Figure 1 is a cross-sectional view illustrating a specific example of the wire-wound golf ball of the present invention < ·-, Summary of the invention According to the present invention, the above purpose has been By increasing the center diameter of the linear golf ball and changing the center, M controls the amount of rotation to be formed, and increases the flying angle M to increase the flying distance. That is, the present invention provides a wire-wound golf ball including a center composed of a vulcanized molded article of a rubber composition, a linear rubber layer formed on the center, and a coating material coated on the linear rubber layer, The diameter of the center is 30 to 35min, and the initial load is 10kg and the final load is 30kg. Invention ^ Detailed Printed by the Employee Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs (please read the precautions on the back before filling out this page) This center can be used, for example, to allocate 5 to 8 0 (preferably 15 to 50) weight Parts of thermoplastic resin are used as fillers to adjust the hardness, 2 to 1 2 (preferably 8 to 10) parts by weight of sulfur, 1 to 4 (preferably 1 to 2) parts by weight of vulcanization accelerator and 10 to 150 (Preferably 50 to 120) parts by weight of the weight modifier, and if necessary, 3 to 10 (preferably 5 to 9) parts by weight of the vulcanized rib agent (K on K) 0 0 parts by weight of the rubber shall prevail , M to obtain a rubber composition, and this rubber composition is obtained by vulcanization molding. In the present invention, the diameter of the center is adjusted to 30 to 35mm, and the strain formed between the initial load (10 kg) and the final greedy load (30 kg) is 1.2 to 2.5 mm, and the wire winding is achieved The reason for the large flying distance of the golf ball while maintaining a good sense of hitting is not clear, but it is considered as follows: It is believed that the diameter of the center through the adjustment is 30 to 35mm, and the initial load of this paper size is suitable for the Chinese national skid Standard (CNS) A4 specifications (210 X 2Θ7 mm) 4 A7 B7 Printed by the Employee Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economy V.

Description of invention (6) As mentioned above, when the center is adjusted by 5 to 8 0 (preferably 15 to 50) Parts of thermoplastic resin are used as stabilizers to adjust the hardness with K, 2 to 12 (preferably 8 to 10) parts by weight of sulfur, 1 to 4 (preferably 1 to 2) parts by weight of vulcanization accelerator, and 10 to ] 50 (preferably 50 to 120) parts by weight of the weight modifier, and if necessary, 3 to 10 (preferably 5 to 9) parts by weight of the vulcanized rib agent (K 1 0 0 parts by weight of the rubber) The rubber composition is composed of vulcanized molded articles. The vulcanization is usually carried out under pressure, under heating at 140 to 170 ° (preferably 150 to 160) for 5 to 30 minutes (preferably 10 to 20 minutes). The rubber used as the center is not particularly limited, and polybutadiene (especially high cis-polybutadiene) with high resilience performance is preferred. It is preferable to use high cis polybutadiene or a rubber containing high cis polybutadiene in the preparation of the rubber composition used as the center. The thermoplastic resin is not particularly limited, and high molecular weight polyolefins such as high styrene resin, high molecular weight polyethylene, high molecular weight polypropylene, etc., or mixtures thereof are preferably used. Printed by the Employee Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs (please read the precautions on the back before filling in this page) Thermoplastic resin to adjust hardness. The thermoplastic resin is used to adjust the hardness of the center, and the amount of the rubber is 5 to 80 parts by weight, preferably 15 to 50 parts by weight, based on the above-mentioned K100 parts by weight of rubber. When the amount of the thermoplastic resin is less than the above range, the hardness of the center cannot be increased sufficiently. Therefore, the hardness becomes the same as that of a general center, and thus cannot provide the desired effect. On the other hand, when the amount of the thermoplastic resin is greater than the above range, the hardness becomes too high, and therefore, the hitting feeling becomes the paper standard applicable to the Chinese National Standard (CNS) Α4 specification (210X297 mm) 6 A7 32S232 — B7 5. Description of the invention (7) Defective, and the processability during rubber kneading also becomes poor. (Please read the precautions on the back before filling in this page) As mentioned above, the amount of sulfur M 0 0 parts by weight of rubber shall be 2 to 12 parts by weight, preferably 8 to 10 parts by weight. When the amount of sulfur is smaller than the above range, the degree of vulcanization becomes low, and therefore, the hardness required for the center cannot be easily obtained. On the other hand, when the amount of sulfur is larger than the above range, the hardness of the center becomes too high, and therefore, the desired effect cannot be obtained. Examples of vulcanizing rib agents include metal oxides (e.g. zinc oxide, magnesium oxide, etc.) and higher fatty acids (e.g. stearic acid, palmitic acid, oleic acid, lauric acid, etc.). This vulcanization rib agent is preferably used for smooth vulcanization, but it is not necessary. The vulcanization accelerator can be any of the vulcanization accelerators that can be used for general sulfur vulcanization, and typical examples thereof include thiazole vulcanization accelerators, such as 2-hydrothiophenyl benzophazole, dibenzo 1 «_yl disulfide , Etc .; bis sulfonamide vulcanization accelerators, such as tetramethyl dihydrocarbon sulfonamide monosulfide, tetramethyl dihydrocarbon sulfonamide disulfide, etc .; sulfenamide sulfide accelerators, such Ν-cyclohexyl-2-benzoxazolylsulfenamide, etc., but not limited to the above. Printed by the Employee Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economy. The curing rib agent and curing accelerator can be formulated according to the amount of sulfur to be formulated. The amount of vulcanization aid Μ 1 0 0 parts by weight of rubber shall prevail, preferably 3 to】 0 parts by weight, especially 5 to 9 parts by weight, the amount of vulcanization accelerator Μ 1 0 0 parts by weight of rubber, It is preferably from 1 to 4 parts by weight, especially from 2 to 2 parts by weight: When the amount is less than the above range, sulfur vulcanization cannot proceed sufficiently. On the other hand, when the amount is larger than the above range, the hardness of the center becomes too high, resulting in a poor hitting feeling. Examples of weight adjusters include barium sulfate, clay, calcium carbonate, and oxide. 7 The paper size is applicable to the Chinese National Standard (CNS) Α4 specification (210X297 mm) A7 B7 5. Invention description (8) Silicon filler, etc., and The amount is as described above, based on 100 parts by weight of rubber, preferably 0 to 150 parts by weight, particularly 50 to 120 parts by weight. When the amount of the weight adjusting agent is smaller than the above range, the weight of the center becomes small, and an appropriate weight of the golf ball cannot be obtained. On the other hand, when the amount of the weight adjusting agent is larger than the above range, the weight of the center becomes large, and therefore, the weight of the ball exceeds the standard value. For the rubber composition used as the center, antioxidants and the like can be added in addition to the above-mentioned components. The structure of the golf ball of the present invention will be described with reference to the drawings. Fig. 1 is a cross-sectional view illustrating a specific example of the wire-wound golf ball of the present invention. In the figure], 1 is the center, 2 is the linear rubber layer, and 3 is the covering material. The center 1 is composed of a vulcanized molded article of a rubber composition, and the diameter of the center is 30 to 35 m πι. Furthermore, the strain of the center formed between the initial greedy load (10 k g) and the final load 〇 0 k g) is in the range of 1.2 to 2.5 m πι. The linear rubber layer 2 is made by winding the linear rubber center, and the so-called wire winding S system is composed of the center and the linear rubber layer 2c. Printed by the Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economy Note on the back and then fill out this page) As for the linear rubber used to form the linear rubber layer 2, the linear rubber that has been used so far can be used. For example, those obtained by vulcanizing a rubber composition (in which sulfur, ribbed rib agent, vulcanization accelerator, antioxidant, etc. are formulated in natural rubber, or natural rubber and synthetic polyisoprene) can be used -The linear rubber layer 2 is covered by the cladding material 3, and 3a is a cavity placed on the cladding material 3, and if necessary, an appropriate number of cavities 3a can be provided according to the required characteristics.
