Abstract

The invention provides a water and oxygen-barrier adhesive, and a preparation method and a use method thereof. The water and oxygen-barrier adhesive comprises a component A, a component B and a component C; wherein the component A includes, by weight, 90-100 parts of hydroxy-terminated polyurethane prepolymer, 26-35 parts of ethyl acetate, and 9-12 parts of butyl acetate; the component B includes,by weight, 95-100 parts of isocyanate-terminated prepolymer and 21-29 parts of ethyl acetate; and the component C includes, by weight, 4-8 parts of a catalyst, 82-90 parts of filler and 9-13 parts ofan organic silicon coupling agent. The adhesive has great water and oxygen-barrier effect. The preparation method is simple. When being used as an adhesive for an aluminum-plastic composite tape, theadhesive can improve the water and oxygen-barrier effect of the tape and prolongs the service life of the aluminum-plastic adhesive tape.

Description

technical field [0001] The invention belongs to the technical field of adhesives, and relates to an adhesive, a preparation method and a use method, in particular to a water and oxygen blocking adhesive, a preparation method and a use method. Background technique [0002] In recent years, my country's wire and cable and communication industries have developed rapidly. However, wires and cables will deteriorate due to water absorption in a humid environment, resulting in signal distortion, so wires and cables are required to have good water resistance. Because the aluminum-plastic composite tape can greatly improve the waterproof performance of the optical cable, and has the advantages of good shielding effect, low cost, light weight, and easy transportation, it has been widely used in the cable industry. [0003] The aluminum-plastic composite tape is generally composed of aluminum foil and polyester film, wherein the aluminum foil and polyester film are laminated with an a...
