Definitions

  • a temperature-sensitive adhesive tape is known as an adhesive tape whose adhesive force can be reversibly controlled by heat (see, for example, Patent Document 1).
  • the conventional temperature-sensitive adhesive tape has a problem that the environmental load when producing the adhesive tape is large because the adhesive layer is formed of a temperature-sensitive adhesive containing an organic solvent.
  • the side chain crystalline (meth) acrylic polymer of this embodiment is a polymer obtained by polymerizing a (meth) acrylate having a linear alkyl group having at least 16 carbon atoms.
  • Examples of the (meth) acrylate having a linear alkyl group having 16 or more carbon atoms constituting the side chain crystalline (meth) acrylic polymer include cetyl (meth) acrylate, stearyl (meth) acrylate, and eicosyl (meth) acrylate. And (meth) acrylates having a linear alkyl group having 16 to 22 carbon atoms, such as behenyl (meth) acrylate, and these may be used alone or in combination of two or more.
  • (Meth) acrylate means acrylate or methacrylate. This is the same for other (meth) acrylates.
  • polar monomers include ethylenically unsaturated monomers having a carboxyl group such as acrylic acid, methacrylic acid, crotonic acid, itaconic acid, maleic acid and fumaric acid; 2-hydroxyethyl (meth) acrylate, 2-hydroxypropyl Examples thereof include ethylenically unsaturated monomers having a hydroxyl group such as (meth) acrylate and 2-hydroxyhexyl (meth) acrylate, and these may be used alone or in combination of two or more.
  • Each of the above-mentioned monomers is, for example, 20 to 100 parts by weight of (meth) acrylate having a linear alkyl group having 16 or more carbon atoms, and 0 to 70 parts by weight of (meth) acrylate having an alkyl group having 1 to 6 carbon atoms. It is preferable to polymerize the polar monomer at a ratio of 0 to 10 parts by weight.
  • a reactive fluorine compound can be further polymerized to the side chain crystalline (meth) acrylic polymer of the present embodiment.
  • the releasability due to the reactive fluorine compound is added, and therefore the peelability of the pressure-sensitive adhesive layer can be improved.
  • Examples of commercially available reactive fluorine compounds include “Biscoat 3F”, “Biscoat 3FM”, “Biscoat 4F”, “Biscoat 8F”, “Biscoat 8FM” manufactured by Osaka Organic Chemical Industry Co., Ltd., Kyoeisha Chemical Co., Ltd. “Light Ester M-3F” manufactured by the same company.
  • the weight average molecular weight of the side chain crystalline (meth) acrylic polymer is preferably 450,000 or more, more preferably 1,000,000 or more.
  • the upper limit of the weight average molecular weight of the side chain crystalline (meth) acrylic polymer is preferably 3 million or less, but is not limited thereto.
  • the weight average molecular weight is a value obtained by measuring by gel permeation chromatography (GPC) and converting the obtained measurement value to standard polystyrene. Examples of the measurement solvent for GPC include tetrahydrofuran (THF).
  • the above-described monomer polymerization is preferably performed by bulk polymerization. Thereby, an adhesive composition can be made into the state which does not contain an organic solvent.
  • the bulk polymerization is preferably performed while irradiating UV. Thereby, the monomer can be polymerized in a relatively short time. Therefore, the side-chain crystalline (meth) acrylic polymer of this embodiment is obtained by adding a photoradical initiator, which will be described later, to a monomer containing a (meth) acrylate having a linear alkyl group having at least 16 carbon atoms. It is preferable that the polymer is polymerized by bulk polymerization while irradiating.
  • the term “monomer” is not limited to an acrylic monomer, but includes a reactive fluorine compound and the like as long as it includes a (meth) acrylate having a linear alkyl group having at least 16 carbon atoms. is there.
  • the polymerization temperature in the bulk polymerization is preferably 30 to 60 ° C.
  • the polymerization time is preferably 30 seconds to 5 minutes.
  • the intensity of UV is preferably 10 to 100 mW / cm 2 (365 nm).
  • the polymerization conditions are not limited to the polymerization conditions described above as long as the side chain crystalline (meth) acrylic polymer can be synthesized.
  • the pressure-sensitive adhesive composition preferably has the largest total content of side chain crystalline (meth) acrylic polymer and (meth) acrylic monomer.
  • an adhesive composition will contain a side chain crystalline (meth) acrylic polymer and a (meth) acryl monomer as a main component, As a result, the outstanding coating property and adhesive physical property can be exhibited.
  • the ratio of the side chain crystalline (meth) acrylic polymer is 5 to 40% by weight with respect to the total of 100% by weight of the side chain crystalline (meth) acrylic polymer and the (meth) acrylic monomer. It is preferable to polymerize the monomers described above.
  • a film-like air blocking member on the surface of the coating film made of the pressure-sensitive adhesive composition.
  • UV can be irradiated and hardened

  • the application of the temperature-sensitive adhesive tape of the present embodiment is not particularly limited.
  • an adhesive tape in a field that requires low odor and low toxicity and is required to be used in a high temperature environment. Can be suitably used.
