A kind of ultraviolet cured adhesive, comprise the raw material of following parts by weight: aromatic urethane acrylate 10 ~ 30 parts, aliphatic urethane acrylate 15 ~ 40 parts, esters of acrylic acid reactive thinner 20 ~ 50 parts, light trigger 4 ~ 10 parts and sulfur alcohol compound 1 ~ 5 part.
The urethane acrylate synthesized by aromatic isocyanate is called aromatic urethane acrylate, the urethane acrylate obtained by aliphatics and alicyclic isocyanate is called aliphatic urethane acrylate, the CN966J75 (aliphatic urethane acrylate) of such as Sartomer, CN965 (aliphatic urethane acrylate), CN972 (aromatic urethane acrylate) etc., 6363 (aromatic urethane acrylate) of Kening Co., Ltd, 6008 (aliphatic urethane acrylates), 6010 (aliphatic urethane acrylates) etc., the 6120F-80 (aromatic urethane acrylate) of Changxing company, 6146-100 (aromatic urethane acrylate), 615-100 (aliphatic urethane acrylate) etc.,
On the basis of technique scheme, the present invention can also do following improvement.
Further, described esters of acrylic acid reactive thinner is a kind of or several arbitrarily mixture in tetrahydrofuran (THF) acrylate, N,N-DMAA or Isosorbide-5-Nitrae butylene glycol diacrylate.
Further; described light trigger is 2-hydroxy-2-methyl-1-phenyl-acetone, 1-hydroxy cyclohexyl phenylketone, 2-benzyl-2-dimethylamino-1-(4-morpholinyl phenyl)-1-butanone, two (2; 4,6-trimethylbenzoyl) phenylphosphine oxide, isopropyl thioxanthone, benzophenone, a kind of or several arbitrarily mixture in o-benzoyl yl benzoic acid methyl esters.
Further, described sulfur alcohol compound is n-dodecyl mercaptan or tertiary lauryl mercaptan.
Preparation method of the present invention is specific as follows:
By aromatic urethane acrylate 10 ~ 30 parts, aliphatic urethane acrylate 15 ~ 40 parts, esters of acrylic acid reactive thinner 20 ~ 50 parts, light trigger 4 ~ 10 parts and sulfur alcohol compound 1 ~ 5 part add in stirrer successively, being evacuated to vacuum tightness is-0.08 ~-0.05MPa, stir 0.5 ~ 2 hour in 500 ~ 1000 revs/min, stir, naturally hang to room temperature, pack.
The invention has the beneficial effects as follows: adopt a kind of ultraviolet cured adhesive with high elongation rate and low elastic modulus of the present invention, solve the shortcoming that Conventional UV optic-solidified adhesive elongation is low and Young's modulus is high, and condensate performance is excellent, bonding reliability is high, applied widely.
