Benefits of technology

The invention is about a new golf ball design that uses a fast chemical reaction to create a polyurethane cover. The cover is made by injection molding the materials and can contain recycled polyurethane. The ball has a seamless cover layer with a consistent microscopic and molecular structure distribution. The invention also includes a method for making the golf ball and a process for recycling the materials. The golf ball has a flexible cover layer with a Shore D hardness in the range of 20-95 and a flex modulus in the range of 5-310 kpsi. The invention also includes a blend of polyurethane and ionomer, and a golf ball with a fast-chemical-reaction-produced layer. The technical effects of the invention include improved durability, flexibility, and a more efficient manufacturing process.

Problems solved by technology

When polyurethane covers are made by conventional methods, such as by casting, a substantial amount of time and energy are required, thus resulting in relatively high cost.

example 1

[0065] A polybutadiene golf ball core having a diameter of 1.545″, a PGA compression of about 65 and a coefficient of restitution of about 0.770 was obtained. A dimpled cover having a thickness of 0.0675″ was reaction injection molded over the core. The cover comprised Bayflex MP 10000 resin (Bayer). The resulting ball had a PGA compression of 78, a COR of 0.720 and a Shore D cover hardness of 39. The ball met standard durability tests and had an excellent scuff resistance rating of 1. It is expected that this cover also has an excellent cut resistance rating.

example 2

(Prophetic)

[0066] A golf ball core formed from high cis polybutadiene, zinc diacrylate, zinc oxide, zinc stearate, and peroxide initiator is obtained. The core has a diameter of 1.49″.

[0067] The core is covered with a 0.04″ thick mantle layer of RIM polyurethane which has a plaque Shore D hardness of 58, namely Bayflex® 110-50 unfilled (Bayer Corp.). The mantle layer is covered with a 0.055″ thick dimpled outer cover layer of Iotek 8000, 7510 and 7030, and a whitener package. The formulation and properties of the golf ball are shown below on Table 1.

example 3

(Prophetic)

[0068] A golf ball core formed from high-cis polybutadiene, zinc diacrylate, zinc oxide, zinc stearate and peroxide imitator is obtained. The core has a diameter of 1.49″.

[0069] The core is covered with a 0.040″ thick mantle layer of RIM polyurethane having a plaque Shore A hardness of about 90, namely Bayflex® MP 10000 unfilled (Bayer Corp.). The mantle layer is covered with a 0.055″ thick dimpled outer cover layer of Ex 1006 and 1007 (Exxon Corp.) and Iotek 7030 (Exxon Corp.). The formulations and properties of the golf ball are shown below in Table 1.

Abstract

Disclosed herein is a golf ball comprising fast-chemical-reaction-produced component, such as a component which comprises a reaction injection molded polyurethane material. A process of making a golf ball by forming at least one core and / or cover component of the ball by mixing two or more reactants that react and form a reaction product with a flex modulus of 5-310 kpsi in a reaction time of about 5 minutes or less, the component having a thickness of at least 0.01 inches and a demold time of 10 minutes or less is disclosed. In one preferred form of the invention, excess polyurethane from forming golf ball covers is recycled by using it to form golf ball cores.

Description

CROSS REFERENCES TO RELATED APPLICATIONS [0001] The present application is a continuation application of U.S. patent application Ser. No. 09 / 040,798, filed on Mar. 18, 1998.STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT [0002] Not Applicable BACKGROUND OF THE INVENTION [0003] 1. Field of the Invention [0004] The invention relates generally to golf balls, and more particularly to golf balls which contain a fast-chemical-reaction-produced component, such as a core and / or cover layer. [0005] 2. Description of the Related Art [0006] Golf balls comprise, in general, three types. The first type is a multi-piece wound ball wherein a vulcanized rubber thread is wound under tension around a solid or semi-solid core, and thereafter enclosed in a single or multi-layer covering of a tough, protective material. A second type of a golf ball is a one-piece ball formed from a solid mass of resilient material which has been cured to develop the necessary degree of hardness to provid...
