  In the dust removal apparatus for the above purpose, as a basic characteristic of the elastic body portion of the dust removal adhesive roll, it is necessary to have an excellent dust removal capability for removing dust by contact. Further, it is required to have sufficient durability against repeated use, and to remove residual deposits such as dust that cannot be removed by transfer by simple cleaning. Furthermore, it is desirable that a special transfer sheet is not required and the range of selection of the transfer sheet is wide. In addition, it is an essential requirement not to adversely affect the electric circuit board or the like that is the object of dust removal.

  However, in the conventional dust removing device, when using a material such as butyl rubber, acrylic rubber, nitrile rubber, or the like, or a thermoplastic elastomer, polyurethane, or the like as described in Patent Document 1 as the elastic body portion of the dust removing adhesive roll, Any of the above materials can prevent adverse effects on electrical circuit boards, etc., but comprehensively satisfy the above other requirements, that is, dust removal capability, durability, ease of cleaning, and transfer sheet selectivity. Even if is used, it cannot be obtained.

  For example, in the case of the above synthetic rubber, generally, a vulcanizing agent or a vulcanization accelerator is added, and heat and pressure are applied to obtain an elastic body. As the vulcanizing agent, sulfur or organic peroxide is generally used. In this case, it reacts with multiple bonds in the molecule of the material, and an intermolecular bond mediated by added sulfur or peroxide is newly created. By this reaction, the molecular weight of the material increases, and the elasticity and strength of the rubber are dramatically improved accordingly. A rubber having a reduced amount of vulcanizing agent can be obtained by controlling the amount of the vulcanizing agent used. Since this rubber is sticky on the surface, it has conventionally been used as a dust-removing adhesive roll. However, since the vulcanizing agent is a volatile component, the vulcanizing agent is lost due to a change with time, and as a result, aged deterioration such as surface hardening or fragility occurs. If cured, the ability to follow the unevenness of the substrate is lost and the adhesiveness is lost, resulting in a reduction in dust removal capability. On the other hand, when it is desired to soften the hardness in advance, it is necessary to reduce the vulcanizing agent. In this case, however, it becomes a highly adhesive rubber and cannot be used as a dust removing adhesive roll. When polyurethane is used for dust-removing adhesive rolls, the hardness and adhesiveness are controlled using isocyanate instead of the vulcanizing agent, but there are problems such as aging as described above, and sufficient durability is obtained. Absent.

  In addition, the above conventional dust removal adhesive roll requires a cleaning agent such as a dedicated organic solvent according to the material of the elastic body part to remove the remaining deposits such as dust, and sticks to the transfer sheet. Since it is easy, as described in Patent Document 1, there is a problem that it is necessary to adjust and select components of the pressure-sensitive adhesive on the surface of the transfer sheet.

An adhesive roll is provided. In the dust removal pressure-sensitive adhesive roll of the present invention, the elastic body portion is composed of an olefin polymer gel, so that the requirements for dust removal capability, durability, ease of washing, and transfer sheet selectivity are comprehensively satisfied. Can do.

  The polymer gel is a gel in which a polymer is crosslinked to form a three-dimensional network structure, and the solvent is absorbed in the inside to swell. Therefore, the polymer gel is a substance having both intermediate properties of solid and liquid. It is cross-linked by a covalent bond by a chemical reaction, does not dissolve unless it breaks the structure, and is chemically stable. Therefore, it is easy to wash, and the range of selection of the transfer sheet is wide. Moreover, since there are few factors which cause aged deterioration like said synthetic rubber, it is excellent in durability. On the other hand, moderate adhesiveness can be obtained, and ultra-low hardness can be easily realized. Therefore, a dust removal adhesive roll excellent in followability to the unevenness of the substrate can be realized by taking advantage of the properties. As a result, the dust removal capability which is not seen in the conventional dust removal roller is shown. The above features have been experimentally confirmed by the inventors.

  In a second aspect, the present invention is characterized in that in the dust-removing adhesive roll of the first aspect, polyethylene gel or polystyrene gel is used as the olefin polymer gel. With such a configuration, the elastic body portion can be manufactured at low cost using a material that is generally easily available.

  In a third aspect, the present invention is characterized in that in the dust removing adhesive roll according to the first or second aspect, a handle is attached to the core portion in order to enable manual rotation. With such a configuration, dust can be removed by manually rotating the dust removal adhesive roll on the electric circuit board or display board. Dust can be removed flexibly, and a wider range of substrates can be targeted for dust removal.

  In a fourth aspect, the present invention includes the dust removal adhesive roll according to the third aspect and an adhesive transfer sheet, and the dust removal while the outer peripheral surface of the elastic body portion is in contact with the surface of the transfer sheet. There is provided a dust removing device characterized in that an adhesive roll is rotated to allow dust attached to the outer peripheral surface to adhere to the transfer sheet. Dust and the like adhering to the dust removing adhesive roll can be finally attached to the transfer sheet and removed. In the present invention, since the range of selection of the transfer sheet is wide, a transfer sheet that is low in cost, excellent in durability, and easy to manufacture can be selected according to the purpose.

  In a fifth aspect, the present invention provides a dust removing pressure-sensitive adhesive roll according to the first or second aspect and a cylindrical shape configured to be rotatable around an outer peripheral surface having an adhesive transfer sheet and having a central axis as a rotation axis. A cylindrical transfer roll, and adheres to the outer peripheral surface of the elastic body portion by rotating the dust removing adhesive roll and the transfer roll while bringing the outer peripheral surface of the elastic body portion into contact with the surface of the transfer sheet. The present invention provides a dust removing device, wherein the dust is adhered to the transfer sheet. With such a dust removing device, it is possible to automatically perform dust removing work on a substrate to be dust removed. Since the range of selection of the transfer sheet is wide, a transfer sheet that is low in cost, excellent in durability, and easy to manufacture can be selected according to the purpose.
