Embodiment 1

[0156] In a reaction device with a thermometer, a stirrer, a reflux condenser, and a nitrogen inlet pipe, 30 parts by mass of 2EHA, 30 parts by mass of BA, 25 parts by mass of EA, 15 parts by mass of VAc, and 3.5 parts by mass of AAc , 0.2 parts by mass of HEA and 100 parts by mass of ethyl acetate were copolymerized in the presence of a polymerization initiator (azobisisobutyronitrile), and a reaction containing an acrylic polymer with a weight average molecular weight of 980,000 was obtained. liquid.

[0157] To the obtained reaction solution, 2 parts by mass (1.9 parts by mass with respect to 100 parts by mass of the solid content of the acrylic polymer) of a polyisocyanate crosslinking agent, 4.4 parts by mass (with respect to 100 parts by mass is 4.2 parts by mass) of the triazole-based ultraviolet absorber 1 to prepare an acrylic adhesive 1 .

[0158] On one side of a low-density polyethylene resin film (thickness 50 μm), apply an acrylic adhesive at room temperature (2...

Embodiment 2～18、 comparative example 1

[0161] Acrylic adhesives were prepared according to the formulations described in Table 1, and adhesive films 2 to 13 and 14 to 19 were produced in the same manner as in Example 1 using this acrylic adhesive.

Abstract

The present invention provides an adhesive film for protecting an automobile wheel, which has a base layer and an adhesive layer, and which is characterized in that the adhesive layer is formed of an acrylic adhesive that contains a (meth)acrylic polymer that has at least a repeating unit derived from a monomer having a crosslinkable functional group and a repeating unit derived from a (meth)acrylic acid alkyl ester having 1-14 carbon atoms, a crosslinking agent and an ultraviolet absorbent. This adhesive film for protecting an automobile wheel exhibits sufficient adhesion when an automobile is transported or displayed, and is able to be easily removed even after outdoor exposure, while being not susceptible to leaving adhesive residue.

Description

[technical field] [0001] The present invention relates to an adhesive film for automobile hub protection. [Background technique] [0002] During transportation and storage of automobiles, water may infiltrate automobile hubs such as aluminum wheels from the outside, and as a result, disc brakes may be rusted. Therefore, bonding of an adhesive film to the surface of the hub to prevent water from entering the inside of the hub has been performed. [0003] For such an adhesive film for wheel hub protection, it is required to maintain an adhesive force to the extent that it can maintain a bonded state until the delivery of the car. No adhesive residue occurs on the surface. [0004] In addition, in recent years, automobiles have been transported over long distances before delivery or exhibited outdoors for a long time. If the conventional adhesive film is used to protect the hub of the automobile, the adhesive film may become difficult to maintain. Peeling, or adhesive residu...
