Adhesive sheet for tire

Abstract

A pressure-sensitive adhesive sheet for a tire which has a base material and a pressure-sensitive adhesive layer, wherein said pressure-sensitive adhesive layer comprises a hot-melt type adhesive composition and further satisfies the following pressure-sensitive adhesion characteristics (A) and (B): (A) it exhibits a value of 7 N / 25 mm or more in terms of the pressure-sensitive adhesion strength to a SBR plate at 5 DEG C, and (B) it exhibits a value of 7 N / 25 mm or more in terms of the pressure-sensitive adhesion strength to a SBR plate at 40 DEG C. The above pressure-sensitive adhesive sheetexhibits a high pressure-sensitive adhesion strength to a tire in a wide range of temperature region and has a good pressure-sensitive adhesion strength also to a studless tire.

Description

technical field The present invention relates to an adhesive label for tires that has strong adhesion to tires in a wide temperature range and has good adhesion even to non-studded tires. Background technique In the past, stickers for tires called tire display trademarks, etc., were well known. In order to convey tire information and increase customers' desire to buy, it will have the manufacturer, brand, model (width, curvature, rim ratio), and usage of the tire marked on it. The sticky label of the tire display part such as precautions, etc., is pasted around the tire including the ground and used. That is to say, the adhesive label for tires generally uses a film with an aluminum vapor deposition layer as a support, and contains an adhesive layer mainly composed of rubber-like resin or alkyl acrylate resin on the support. constitute. In addition, it is also disclosed that polypropylene is used as the main component as the surface substrate, and a white film composed of...

Problems solved by technology

In addition, since the mold release agent used in the manufacture of tires adheres to the surface of the tire to some extent, there is also a problem that the adhesive labels for tires that have already been attached tend to peel off during storage or transportation of the tires.
