The solvent acrylate pressure sensitive adhesive with different thickness are prepared by solution polymerization using soft monomer 2-ethylhexyl acrylate,hard monomer functional mono-mer acrylic acid and solvent ethyl acetate as raw materials.The effects of different functional mon-omer concentrations on the performance of acrylate pressure-sensitive adhesive are investigated.The results show that when the thickness of the adhesive layer is 30 μm,and the concentration of acrylic acid is 10.96%,the maximum peel strength of the acrylate is 2 730.5 gf·(25 mm)-1at 180°.When the thickness of the adhesive layer is 30 μm,and the acrylic acid concentration is 5.80%,the maximum initial adhesive strength of the ring is 16.559 N·(25 mm)-1.When the thickness of the adhesive layer is 20 μm and the acrylic acid concentration is 8.45%and 10.96%,the displacement is 0.5 mm with good adhesion.Therefore,when the thickness of the adhesive layer is 30 μ m and the concentration is 8.45%,the comprehensive performance of the acrylate pressure sensitive adhesive is better.
