Title
(EN) ADHESIVE TAPE
(FR) RUBAN ADHÉSIF
(JA) 粘着テープ
Abstract
(EN)
[Problem] To provide an adhesive tape which can reduce a hammering noise or a rubbing noise, can prevent an object covered with the adhesive tape from staining caused by the contamination by dust or dirt or the intrusion of water or an oil, has durability against puncture or abrasion, and can be bent easily after objects are tied to each other with the adhesive tape. [Solution] An adhesive tape which is provided with a base material comprising 100 parts by mass of polyvinyl alcohol, an elastomer in an amount of 10 to 100 parts by mass relative to 100 parts by mass of the polyvinyl alcohol, and a plasticizer in an amount of 10 to 100 parts by mass relative to 100 parts by mass of the polyvinyl alcohol, wherein the elastomer contains an acrylonitrile monomer unit and at least one monomer unit selected from the group consisting of a chloroprene monomer unit, a butadiene monomer unit and an isoprene monomer unit, and the damping value in a sound adsorption test on the adhesive tape is 2 dB or more.

L'invention fournit un ruban adhésif qui permet de réduire un bruit de tapotement ou de griffure, qui permet d'inhiber la souillure d'un objet à revêtir par contamination par des poussières et des saletés, et par infiltration d'une eau ou d'une huile, qui possède une durabilité vis-à-vis des piqûres et des griffures, et qui se plie facilement après liaison de l'objet à revêtir. Plus précisément, l'invention concerne un ruban adhésif qui possède un substrat contenant 100 parties en masse d'un polychlorure de vinyle, et un élastomère à raison de 10 à 100 parties en masse ainsi qu'un plastifiant à raison de 10 à 100 parties en masse, pour 100 parties en masse dudit polychlorure de vinyle. Ledit élastomère contient une unité monomère d'acrylonitrile, et au moins une unité monomère choisie parmi une unité monomère de chloroprène, une unité monomère de butadiene et une unité monomère d'isoprène. La valeur d'atténuation lors d'un essai d'absorption acoustique dudit ruban adhésif, est supérieure ou égale à 2dB.
