Abstract

The invention relates to a water-based adhesive suitable for bonding leather and non-polar plastic substrates. The adhesive is compounded from various raw materials, and the raw materials include VAE emulsion, water-based binder, water-based polyurethane emulsion, water-based Rubber emulsion, water-based terpene resin emulsion and surfactant. This environmentally friendly water-based adhesive is suitable for bonding between different leather materials and non-polar plastic substrates such as PP and PE. It has good initial tack and final tack, and has an open time that can adapt to high-speed gluing machines. No pollution, no mildew, can be widely used in the field of packaging.

Description

Technical field [0001] The invention relates to a water-based adhesive and a preparation method thereof, in particular to an environmentally-friendly water-based adhesive with excellent initial and final viscosity suitable for leather-plastic substrates and a preparation method thereof. Background technique [0002] As the concept of protecting the environment and cherishing resources has become more and more popular, more and more attention has been paid to environmentally friendly factors such as high solid content, solvent-free, water-based, light curing and energy-saving technologies such as low-temperature curing and waste recycling. Continuously increase research and development efforts. In the field of flexible packaging, solvent-free adhesives and water-based adhesives are mainly used in the composite production of flexible packaging in developed countries in Europe and America. At present, more than 95% of my country's flexible packaging production uses solvent-based ad...
