AI Technical Summary
Existing adhesive compositions for rubber composites, particularly in tire manufacturing, often rely on resorcinol-formaldehyde (RF) components, which are harmful to human health and require costly management and disposal. Additionally, these compositions may lack sufficient adhesive strength and processability.
The development of an eco-friendly adhesive composition comprising a latex, polyurethane, an amine-based adhesion promoter, and a water-containing solvent, with a specific viscosity range of 2.50 to 3.00, to enhance adhesive strength and coating processability while avoiding RF components.
The proposed adhesive composition achieves excellent adhesive strength, proper pick-up, and improved manufacturing processability, while being environmentally friendly and reducing post-treatment costs.
