Description
本創作關於一種高爾夫球結構，特別是關於一種包含能夠提升高爾夫球的操控性與耐用性的熱塑性聚氨酯組合物的高爾夫球結構。The present invention relates to a golf ball structure, and more particularly to a golf ball structure comprising a thermoplastic polyurethane composition capable of improving the handling and durability of a golf ball.
隨著時代的進步，為了保持自身健康的水平，全世界皆掀起一股運動的熱潮。依據經濟部統計處的資料顯示，體育用品產值可高達新臺幣418億元。而在各式運動中，由於高爾夫球本身的運動強度較低，適於學習的人口層面廣，且高爾夫球可結合商務交流並作為一種社交活動，因此，高爾夫球的相關用品極具商機。With the advancement of the times, in order to maintain the level of their own health, the world has set off a wave of sports. According to the statistics of the Statistics Department of the Ministry of Economic Affairs, the output value of sports goods can reach as high as NT$41.8 billion. In all kinds of sports, because the golf ball itself has low exercise intensity, the population suitable for learning is wide, and the golf ball can be combined with business communication and as a social activity. Therefore, golf related articles are highly profitable.
目前市售之高爾夫球可具有單層或多層結構，而具有多層結構的高爾夫球可依照場地、所使用的球桿與打者的習慣等不同因素，提供不同組成的高爾夫球。因此，具有多層結構的高爾夫球相較於單層結構的高爾夫球具有較大的開發潛力。在具有多層結構的高爾夫球中，由於高爾夫球的表層直接與球桿接觸，因此高爾夫球的表層為影響其功能性的重要因素之一。Currently commercially available golf balls may have a single layer or a multi-layer structure, and golf balls having a multi-layer structure may provide golf balls of different compositions depending on factors such as the venue, the club used and the habit of the hitter. Therefore, a golf ball having a multi-layer structure has a large development potential compared to a golf ball having a single-layer structure. In a golf ball having a multi-layer structure, since the surface layer of the golf ball is directly in contact with the club, the surface layer of the golf ball is one of important factors affecting its functionality.
現今高爾夫球的表層主要為離子聚合型樹脂層，例如：杜邦 TM(DU PONT)公司所生產的沙林®樹脂 (Surlyn ®)。由於Surlyn ®具有良好的反彈性、耐用性與加工性，因此被廣泛地作為高爾夫球表層。然而Surlyn ®因為具有較大的硬度，其經過較大角度的球桿揮擊後，產生的後旋轉速有限，相應降低切球的功效。因此，當使用Surlyn ®作為表層結構的高爾夫球被擊上果嶺後，較容易出現滾動現象，亦即該高爾夫球產生不停球的現象，且該高爾夫球的表層結構容易受損，導致需要時常更換新的高爾夫球。因此，有必要開發一種能夠提升高爾夫球的操控性與耐用性的高爾夫球結構。 Today the major golf ball surface ionic polymeric resin layer, for example: DuPont TM (DU PONT) ® produced by the company sarin resin (Surlyn ®). Because Surlyn ® has a good bounce, durability and processability, it is widely used as golf ball cover. However, because the Surlyn ® has a larger hardness, after it passes through a large angle swing the club, the speed of rotation produced limited, a corresponding reduction in chipping effect. Therefore, when using Surlyn ® surface structure as a golf shot on the green, the more prone to rolling phenomenon, namely the phenomenon of the golf ball produces non-stop, and the surface structure of the golf ball is easily damaged, resulting in the need Change new golf balls from time to time. Therefore, it is necessary to develop a golf ball structure capable of improving the handling and durability of a golf ball.
鑒於上述問題，本創作之目的為提供一種高爾夫球結構，藉由提升高爾夫球的操控性與耐用性，以改善上述習知技術所產生的問題。In view of the above problems, the object of the present invention is to provide a golf ball structure which improves the problems caused by the above-mentioned conventional techniques by improving the handling and durability of the golf ball.

步驟S11、S12與S13中，分別先將多異氰酸酯與多元醇組合物混合，並加熱反應以獲得預聚物。其中，以莫耳數5：1的比例混合第一多異氰酸酯與第一多元醇組合物後，使其反應並獲得第一預聚物；以莫耳數4：1的比例混合第二多異氰酸酯與第二多元醇組合物後，使其反應並獲得第二預聚物；以莫耳數3：1的比例混合第三多異氰酸酯與第三多元醇組合物後，使其反應並獲得第三預聚物。其中，第一多異氰酸酯、第二多異氰酸酯與第三多異氰酸酯可為相同或不同；第一多元醇組合物、第二多元醇組合物與第三多元醇組合物可為相同或不同。In steps S11, S12 and S13, the polyisocyanate is first mixed with the polyol composition, and the reaction is heated to obtain a prepolymer. Wherein the first polyisocyanate and the first polyol composition are mixed in a molar ratio of 5:1, and then reacted to obtain a first prepolymer; the second most mixed in a molar ratio of 4:1. After the isocyanate and the second polyol composition, the reaction is carried out to obtain a second prepolymer; the third polyisocyanate and the third polyol composition are mixed in a molar ratio of 3:1, and then reacted and A third prepolymer is obtained. Wherein, the first polyisocyanate, the second polyisocyanate and the third polyisocyanate may be the same or different; the first polyol composition, the second polyol composition and the third polyol composition may be the same or different .
步驟S21、S22與S23中，分別將獲得的預聚物與擴鏈劑組合物混合，並進行擴鏈反應以獲得聚氨酯。其中，以莫耳數6：4的比例混合第一預聚物與第一擴鏈劑組合物，使其反應並獲得第一聚氨酯；以莫耳數5：3的比例混合第二預聚物與第二擴鏈劑組合物，使其反應並獲得第二聚氨酯；以莫耳數4：2的比例混合第三預聚物與第三擴鏈劑組合物，使其反應並獲得第三聚氨酯。其中，第一擴鏈劑組合物、第二擴鏈劑組合物與第三擴鏈劑組合物可為相同或不同。In steps S21, S22 and S23, the obtained prepolymer and the chain extender composition are respectively mixed and subjected to a chain extension reaction to obtain a polyurethane. Wherein, the first prepolymer and the first chain extender composition are mixed in a molar ratio of 6:4, reacted to obtain a first polyurethane; and the second prepolymer is mixed at a molar ratio of 5:3.

The properties of the polyurethane composition can be controlled by adjusting the ratio of the first polyurethane, the second polyurethane to the third polyurethane. Since the polyisocyanate and chain extender composition are hard segments, the hard segment forms a crystalline region due to intermolecular forces, and the properties are brittle and hard, while the polyol composition belongs to a soft bond segment, which absorbs stress to maintain high The shape of the molecule is more flexible. Therefore, when the polyurethane composition is required to have a high hardness, more hard segments can be mixed to increase the hardness. Therefore, the thermoplastic polyurethane composition contained in the golf structure of the present invention can adjust the mixing ratio according to different needs, so that the creation can be used as a golf ball structure with wide application.

表3為根據表2的配方進行耐打與耐切性測試的結果。耐打測試係利用美國ADC炮擊測試機進行測試。而耐切測試係使用台灣自製高爾夫球打擊機，於桿面60度時進行測試。其中，由耐打測試可知，相較於僅能承受250下與300下的配方2與配方3，配方1可承受500下以上仍未破裂，因此配方1具有較佳之耐打性。而由耐切性測試中可知，相較於僅能承受35下與40下的配方2與配方3，配方1維持100下以上時才出現裂痕，因此配方1具有較佳之耐切性。Table 3 shows the results of the resistance test and the cut resistance test according to the formulation of Table 2. The resistance test was conducted using the US ADC bombardment tester. The cut-resistant test was carried out using a Taiwan-made golf hitting machine at 60 degrees on the face. Among them, it can be seen from the resistance test that the formulation 1 can withstand more than 500 times without breaking, as compared with the formulation 2 and the formulation 3 which can only withstand 250 and 300, and therefore the formulation 1 has better resistance to abrasion. From the endurance test, it can be seen that the formulation 1 has better cut resistance than the formulation 2 and the formulation 3 which can only withstand 35 and 40, and the formulation 1 is maintained at 100 or more.
接續上述較佳實施例，在本創作之一更佳實施例中，將配方1的熱塑性聚氨酯混合物與聚醚胺組合物進行物理混摻，其混摻的重量比如表4所示。Following the preferred embodiment described above, in a preferred embodiment of the present invention, the thermoplastic polyurethane blend of Formulation 1 was physically blended with the polyetheramine composition, and the weight of the blend was as shown in Table 4.

如表4所示，其中，聚醚胺組合物可選自聚醚胺類、多異氰酸酯、或其組合。聚醚胺組合物較佳地為聚醚胺(Jeffamine ®D-4000，polyetheramine，分子量4000)、聚醚胺(Jeffamine ®T-4000，polyetheramine，分子量4000)、MDI或其組合。此外，進行完成品1與完成品2之性質測試，其測試結果如表5所示。 As shown in Table 4, wherein the polyetheramine composition may be selected from the group consisting of polyetheramines, polyisocyanates, or combinations thereof. The composition is preferably a polyether amine is a polyether amine (Jeffamine ® D-4000, polyetheramine , molecular weight 4000), the polyether amine (Jeffamine ® T-4000, polyetheramine , molecular weight 4000), the MDI or combinations thereof.

表5為根據表4的配方進行反彈係數COR測試與耐切性測試的結果。反彈係數COR測試係利用美國ADC炮擊測試機進行測試。而耐切測試係使用台灣自製高爾夫球打擊機，於桿面60度時進行測試。如表5所示，其中，相較於未添加聚醚胺組合物的完成品1，完成品2可使含有其之高爾夫球的反彈係數及耐切性有明顯之提升。Table 5 shows the results of the rebound coefficient COR test and the cut resistance test according to the formulation of Table 4. The rebound coefficient COR test was tested using the US ADC bombardment tester. The cut-resistant test was carried out using a Taiwan-made golf hitting machine at 60 degrees on the face. As shown in Table 5, the finished product 2 can significantly improve the rebound coefficient and the cut resistance of the golf ball containing the same as the finished product 1 to which the polyetheramine composition is not added.
於實務上，將配方1的熱塑性聚氨酯混合物與聚醚胺組合物進行物理混摻後，所獲得的完成品2的塑膠粒即可作為商業販售產品。消費者購買所述塑膠粒後，可藉由各種塑膠粒的加工方式進行使用，例如：使用射出成型機將所述塑膠粒進行射出成型。其中，因為各種塑膠粒的加工方式皆包含加熱，因此於加工製程中，所述塑膠粒會因為溫度上升，在射出成型機內快速反應，並產生交聯 (cross-link)的情況。當溫度上升後，所含有的MDI會與聚醚胺的胺基 (-NH 2)反應，形成聚脲 (polyurea)，使所述塑膠粒形成性質更為強韌的聚氨酯-聚脲 (polyurethane-polyurea)的形式。 In practice, after the thermoplastic polyurethane mixture of Formulation 1 and the polyetheramine composition are physically blended, the obtained plastic pellet of Finished Product 2 can be used as a commercial product. After the consumer purchases the plastic granules, the plastic granules can be processed by various processing methods, for example, the plastic granules are injection molded using an injection molding machine. Among them, since the processing methods of various plastic granules include heating, in the processing process, the plastic granules rapidly react in the injection molding machine due to temperature rise, and cross-linking occurs. When the temperature rises, the MDI contained will react with the amine group (-NH 2 ) of the polyetheramine to form polyurea, which makes the plastic particles form a more rigid polyurethane-polyurea. The form of polyurea).
接續上述實施例，使用射出成型機將完成品2製成高爾夫球，並與市售高爾夫球進行分析比較。Following the above embodiment, the finished product 2 was made into a golf ball using an injection molding machine, and analyzed and compared with a commercially available golf ball.

如第3圖所示，球心內層100可選用BR人造膠及添加物，控制溫度於約160~170℃，進行熱壓成型，並將尺寸研磨至直徑35~42 mm。中間層200係選用離子型樹脂 (IONOMER RESIN)，控制溫度於約170~180 ℃，進行第二層射出成型，其射出厚度為0.5~2 mm。外層300係選用完成品2的塑膠粒，控制溫度於約180~220 ℃，進行表層射出成型，其射出厚度為0.1~1.5 mm。此外，實施例二可做為高爾夫練習球或比賽球。由於實施例二製程較為複雜，但其具備有緩衝效果的中間層，因此較佳地，實施例二可做為高爾夫比賽球。As shown in Fig. 3, the inner core layer 100 can be made of BR artificial glue and additives, and the temperature is controlled at about 160-170 ° C for hot press forming, and the size is ground to a diameter of 35 to 42 mm. The intermediate layer 200 is made of an ionic resin (IONOMER RESIN), and the second layer is injection-molded at a controlled temperature of about 170 to 180 ° C, and has a thickness of 0.5 to 2 mm. The outer layer 300 is made of plastic pellets of finished product 2, and the temperature is controlled at about 180-220 ° C for surface injection molding, and the thickness of the injection is 0.1 to 1.5 mm. In addition, the second embodiment can be used as a golf practice ball or a game ball. Since the process of the second embodiment is relatively complicated, but it has an intermediate layer with a buffering effect, it is preferable that the second embodiment can be used as a golf game ball.

如表6所示，將實施例三，亦即自有品牌VPLUS的練習球，與原設計Surlyn ®外皮練習球進行上述測試。可得知，使用熱塑性聚氨酯組合物作為外層的實施例三，其之各種手感與耐打性皆有明顯提升。此外，將其與市面上同等級練習球，例如：知名高爾夫品牌Bridgestone的練習球，進行比較。可知，實施例三的壓縮程度及表面硬度較低，因此可改善傳統練習球打擊手感過硬的問題，且亦不因為壓縮程度低，而導致反彈係數下降，仍保持高反彈係數以維持飛行距離。同時，實施例三使用60球桿以40 m/s速度進行耐打測試，於擊球100次後並無發現表面受損，可知其可達到柔軟又耐切的效果。此外，實施例三經過ADC炮擊測試以160 f/s速度連續打擊下，可承受至少500次以上撞擊，代表其具有良好的耐用性。因此可知，實施例三之搭配方式不論是手感、耐打性不僅優於傳統Surlyn ®外層練習球，且手感、距離皆優於市面上同等級知名品牌。 As shown in Table 6, the third embodiment, i.e., its own brand VPLUS practice balls, to perform such tests with the original design Surlyn ® sheath practice balls. It can be seen that in the third embodiment using the thermoplastic polyurethane composition as the outer layer, various hand feelings and resistance to abrasion are significantly improved. In addition, compare it to the same level of practice balls on the market, such as the ball of the famous golf brand Bridgestone. It can be seen that the compression degree and the surface hardness of the third embodiment are low, so that the problem of the traditional practice ball hitting hard feeling can be improved, and the rebound coefficient is not lowered due to the low degree of compression, and the high rebound coefficient is maintained to maintain the flight distance. At the same time, in the third embodiment, the 60-ball was used for the resistance test at a speed of 40 m/s, and no surface damage was observed after hitting the ball 100 times, and it was found that it could achieve a soft and cut-resistant effect. In addition, the third embodiment can withstand at least 500 impacts after being continuously struck by the ADC bombardment test at a speed of 160 f/s, indicating that it has good durability. Thus it is seen, according to a third embodiment with a way of either feel resistance, resistance to fight not only the outer layer of Surlyn ® is superior to the traditional practice balls, and feel, better than the market are from the same class of well-known brands.
實施例四之球心內層100的直徑為38.5 mm、中間層200的厚度為1. 35 mm且外層300厚度為0.8 mm，因此可得球體的直徑為42.8 mm成品。其與市售之高爾夫球產品分別進行上述測試，測試結果如表7所示。The core inner layer 100 of the fourth embodiment has a diameter of 38.5 mm, the intermediate layer 200 has a thickness of 1.35 mm, and the outer layer 300 has a thickness of 0.8 mm, so that the spherical body has a diameter of 42.8 mm. The above tests were carried out separately from the commercially available golf products, and the test results are shown in Table 7.

如表7所示，將實施例四，亦即自有品牌VPLUS的比賽球與原設計Surlyn ®外皮比賽球比較後可得知，使用熱塑性聚氨酯組合物作為外層的實施例四，其之手感與表面耐切性皆有明顯提升。此外，與知名高爾夫品牌Titleist PRO V1、PRO V1x的兩種比賽球進行比較。可知，實施例四可降低整顆球的壓縮，使得打者擊球時的手感提升，亦不會因為壓縮較多而減少飛行距離 (COR)。同時，實施例四相較於知名品牌更為柔軟，其可於短距離揮擊時產生更強力後旋，以增加落地時停球性，減少滾動。此外，實施例四球使用60球桿以40 m/s速度進行耐打測試，於擊球100次後並無發現表面受損，可知其可達到柔軟又耐切的效果。因此可知，實施例四之此搭配方式不論是手感、耐切性皆優於傳統Surlyn ®外層比賽球，且在手感、距離、耐切性，皆優於市面上同等級知名品牌。 As shown in Table 7, the fourth embodiment, i.e., the own brand VPLUS original game ball game ball sheath Surlyn ® comparison with the known design, a thermoplastic polyurethane composition as the outer layer of the fourth embodiment, which is the feel and The surface cut resistance is obviously improved. In addition, it is compared with the two game balls of the famous golf brands Titleist PRO V1 and PRO V1x. It can be seen that the fourth embodiment can reduce the compression of the whole ball, so that the feel of the hitter when hitting the ball is improved, and the flight distance (COR) is not reduced because of the more compression. At the same time, the fourth embodiment is softer than the well-known brands, which can produce a stronger back spin when swiping in a short distance, so as to increase the ball stopping when landing, and reduce rolling. In addition, the fourth ball of the example was subjected to a resistance test at a speed of 40 m/s using a 60-ball, and no surface damage was observed after hitting the ball 100 times, and it was found that it was soft and cut-resistant. Thus understood, according to a fourth embodiment of this embodiment with both feel, cut resistance properties are superior to the conventional Surlyn ® outer ball game, and the touch distance, cut resistance properties, are better than the same level of well-known brands on the market.
