PURPOSE:To provide an antivibration rubber sheet which is small in repulsion when it is bent, can be wound without afraid of blocking, which sheet is utilized while being wound around a refrigerant piping in a room air conditioner or car air conditioner. CONSTITUTION:An adhesive layer is formed on one side of a rubber sheet 1, while a soft blocking preventive paint 2 serving as primer for adhesive agent is formed on the other side. As a viscous layer, the adhesive agent alone or the adhesive agent applied to a core in the form of a double-sided tape is used. As the adhesive agent, acrylic adhesive agent 3 is preferably used in view of excellent heat resistance and wet resistance. By applying the blocking preventive paint 2 on the surface, the rubber sheet 1 is free from blocking characteristic, stickiness, and dirt for hands. Acryl, vinyl acetate, vinyl chloride alone and their copolymer resin is adapted to the blocking preventive paint, so that closability to the acrylic viscous agent 3 is improved and repulsion is reduced through its softness. |
