Golf Ball Paint Composition for Abrasion Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The surface paint film layer of golf balls lacks sufficient abrasion resistance, which affects the durability and performance of the balls, particularly in terms of spin rate stability and durability during repeated impacts.
Innovation Solution
A golf ball paint composition using an acrylic polyol with a weight-average molecular weight of 30,000 to 120,000 and a hydroxyl value of at least 120 mgKOH/g, combined with a polyisocyanate, such as hexamethylene diisocyanate, to achieve an elastic work recovery of 70% or more, enhancing the paint film's elastic strength and self-repairing ability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the paint film layer is made soft to improve spin rate stability, then the spin rate stability is improved, but the abrasion resistance deteriorates
Solution Approach 1:
The patent changes the chemical composition parameters of the polyol (using acrylic polyol with specific hydroxyl value and molecular weight) and controls the NCO/OH ratio to achieve optimal elastic work recovery (70% or more). This parameter optimization allows the paint film to simultaneously achieve softness for spin rate stability and high abrasion resistance through enhanced self-repairing ability.
Solution Approach 2:
The patent creates a composite urethane paint system combining acrylic polyol with polyisocyanate in specific proportions (NCO/OH ≥ 1.00). This composite material structure enables the paint film to exhibit both the softness needed for spin rate stability and the durability required for high abrasion resistance, resolving the contradiction between these two properties.
2Ease of manufacture
If conventional polyol is used to simplify the paint composition, then the ease of manufacture is improved, but the abrasion resistance deteriorates
Solution Approach 1:
The patent specifies precise parameter ranges for the acrylic polyol (hydroxyl value ≥ 120 mgKOH/g, molecular weight 30,000-120,000) and controls the NCO/OH ratio to achieve optimal elastic work recovery. These parameter specifications ensure high abrasion resistance while maintaining relatively simple paint composition and manufacturing processes.
3Strength
If the elastic work recovery is increased to improve self-repairing ability, then the abrasion resistance is improved, but the paint composition complexity increases
Solution Approach 1:
The patent achieves high elastic work recovery (70% or more) by optimizing specific parameters: using acrylic polyol with hydroxyl value ≥ 120 mgKOH/g and molecular weight 30,000-120,000, and controlling the NCO/OH ratio ≥ 1.00. These targeted parameter adjustments achieve the desired self-repairing ability without requiring complex multi-component formulations.
Solution Approach 2:
The patent employs a relatively simple two-component urethane paint system (acrylic polyol and polyisocyanate) that achieves high elastic work recovery and abrasion resistance through optimized composition ratios, avoiding the need for complex multi-component formulations while maintaining high performance.
