PROBLEM TO BE SOLVED: To obtain a sticky sealing material capable of being peeled or removed in a state of interfacial failure, and excellent in hermetically sealing properties, buffering properties and regulating properties, and further to provide a method for sealing a trim material for interior decoration of a door by which an interferential tap tone between the trim material for the interior decoration of the door and the inner panel face of the door is prevented, the damping properties of the trim material for the interior decoration is improved, and the noise caused by the leakage of wind is prevented. SOLUTION: This sticky sealing material comprises (A) 100 pts.wt. block copolymer composed of a polystyrene and a polyolefin, (B) 50-300 pts.wt. tackifier, (C) 50-400 pts.wt. inorganic filler, (D) 5-20 pts.wt. antifoaming agent and (E) 100-700 pts.wt. softener. The sealing material is coated on the trim material for the interior decoration of the door or the inner panel face of the door, and the trim material for the interior decoration of the door is tightened together with the inner panel face of the door so that the sticky sealing material may be compressed in a space. The sticky sealing material is also stuck to the inner panel face side of the door or the trim material side for the interior decoration of the door, and when the trim material for the interior decoration of the door is removed, exhibits the adhesion in a state in which the sealing material is peelable. |
