Abstract

The invention provides a flame-retardant and water-resistant ultraviolet curing adhesive. The ultraviolet curing adhesive is prepared from, by weight, 10 to 20 parts of an allyl chloroacetate ionization modified hydroxyl-terminated nano-hybrid hyperbranched polymer, 30 to 40 parts of cinnamic acid modified hyperbranched polytetrahydrofuran, 1 to 3 parts of 16,17-epoxypregnenolone acetate, 3 to 5 parts of (R)-limonene oxide modified 2,4,6-tri(4-aminophenyl)-1,3,5-triazine and 1 to 3 parts of a photoinitiator. The invention also discloses a preparation method of the flame-retardant and water-resistant ultraviolet curing adhesive. The ultraviolet curing adhesive disclosed by the invention is good in comprehensive performance, relatively low in brittleness, high in weather resistance, water resistance, flame retardance, ultraviolet resistance and cold and hot impact resistance, high in bonding strength, long in service life and high in economic value, social value and ecological value.

Description

technical field [0001] The invention relates to the technical field of glue, in particular to a flame-retardant and water-resistant UV-curable glue and a preparation method thereof. Background technique [0002] In recent years, with the development of the times, the improvement of people's aesthetic concepts and the continuous improvement of various industry standards, higher requirements have been put forward for the glue used for bonding between different objects, not only requiring high bonding strength, but also It is also required to have sufficient toughness, fast curing speed and environmental friendliness. It is in this situation that UV-curable adhesives have come into people's sight, and its appearance has attracted widespread attention. [0003] UV light curing adhesive is to add a photoinitiator to the resin. After absorbing the high-intensity ultraviolet rays in the ultraviolet light curing equipment, active free radicals are generated, thereby initiating poly...
