The invention discloses a preparation method of an
ultraviolet-cured acrylic ester hot-melt pressure-sensitive
adhesive. The
ultraviolet-cured acrylic ester hot-melt pressure-sensitive
adhesive for an
adhesive tape is in the form of a non-
solvent 100-percent
hot melt adhesive, is mainly prepared from an acrylic ester series
polymer, a photo-initiator component binding to a main chain of the
polymer, and a tackifying resin which is adopted as required, can be cured rapidly under the
radiation of
ultraviolet C (the
wavelength is 190 to 280 nanometers), has
high heat resistance characteristic at the temperature of 120 to 140 DEG C, can be applied to industrial adhesive tapes, can be taken as a bonding agent for automobile heating components, has the characteristics of nontoxicity, safety,
skin affinity and adjustable
glass transition temperature, and can be applied in the field of sanitary and medical products. The ultraviolet-cured acrylic ester hot-melt pressure-sensitive adhesive can be coated under a high
gram weight and at a high speed on the aspect of
coating implementation; the problems of
solvent explosion danger,
solvent discharge and
odor in the solvent type
acrylic acid series pressure-sensitive adhesive are solved.
