Abstract
The invention relates to a reactive-type plasticizer-free SIS hot-melt pressure-sensitive adhesive. The reactive-type plasticizer-free SIS hot-melt pressure-sensitive adhesive comprises the following components in parts by weight: 23-39 parts of thermoplastic elastomer, 4-10 parts of a first functional polymer, 5-30 parts of a second functional polymer, 15-34 parts of a first tackifier, 15-30 parts of a second tackifier, 41-80 parts of a third tackifier, 0.5-2 parts of an anti-aging agent, 0.5-1 part of an antioxidant and 0.5-1 part of a light stabilizer. Since the formula system is free of small-molecule plasticizer and when the formula system is compounded with HDPE polymer sheets, the phenomenon that the plasticizer is dispersed in the polymer sheets cannot be caused and thus the reduction in the tensile property of the sheets and the loss in the property of the adhesive can be effectively avoided.
