HOT-MELT ADHESIVE COMPOSITION WITH EXCELLENT HEAT AND COLD RESISTANCE |
摘要 |
<p>The present invention provides a hot melt adhesive composition comprising an epoxy-modified block copolymer obtained by epoxidizing a carbon-carbon double bond of a conjugate diene component in a block copolymer having a polymer block (A) comprising mainly a vinyl aromatic compound and a polymer block (B) comprising mainly a conjugate diene compound in one molecule, a paraffin wax having a melting point of 40 to 100 DEG C, a tackifier and an antioxidant. The hot melt adhesive composition of the present invention is well compatible with a paraffin wax and a tackifier because it has an epoxy group which is a polar group in a molecule. Further, the hot melt adhesive composition has excellent heat resistance and cold resistance because of a combination of the epoxy-modified bloc copolymer as a base polymer with paraffin wax, and while the melt viscosity is low, the heat resistance is high.</p> |
