Abstract

The invention provides a high-performance polyurethane adhesive. The high-performance polyurethane adhesive is prepared from a component A and a component B; after the component A and the component Bare uniformly mixed in a mass ratio of 5 to 1, the high-performance polyurethane adhesive is obtained. Compared with the traditional high-performance polyurethane adhesive, the high-performance polyurethane adhesive provided by the invention has a wide application range, can be coated at a high concentration (50 percent), is suitable for an aluminized film, an aluminum foil, boiling in water and the like, and has a good appearance effect after use; an adhesive disk is long in service life and meets the requirements of energy saving and environmentally friendly upgrading and updating.

Description

technical field [0001] The invention relates to the technical field of composite film flexible packaging, in particular to a high-performance polyurethane adhesive. Background technique [0002] The adhesive is suitable for the bonding of different materials, different thicknesses, different specifications, and different components. Polyurethane adhesives have excellent low temperature resistance, water resistance, oil resistance and flexibility, and have high bonding strength, and are widely used in industries such as synthetic leather and composite films. However, the existing polyurethane adhesives cannot satisfy the adhesion of various materials at the same time, and can only be used in a targeted manner, especially for flexible packaging materials. At present, there is no polyurethane adhesive that can simultaneously meet the requirements of various flexible packaging materials, and different flexible packaging materials must be added. The components are used to achiev...
