Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to an adhesive dust removing roll that rolls on a surface of, for example, a carpet and collects and removes dust attached to the surface.

[0002]

[Prior art]

 A conventional adhesive dust removing roll is, for example, a long laminated film as shown in a cross-sectional view in FIG. 3 and a core material 5 of the patterned roll shown in FIG. Was wound in this way. In FIG. 3, reference numeral 2 denotes a substrate, which is generally paper. One side is coated or laminated with a polyethylene film 3 to form a back-coated paper, and the polyethylene side 3 is coated with a silicone resin or silicone wax to form a release surface 4, which is adhered to the opposite side of the back-coated paper. Agent 1 was applied.

[0003] The roller is used as a tool that can collect and remove dust such as carpets, floors and tatami mats while rolling the roller, and when the sticky surface is covered with the collected dust, the part is peeled off. If it is cut and removed, it can be used continuously. The part to be peeled off at this time has a release agent layer on the back surface of the film, so that it can be easily peeled off from the new pressure-sensitive adhesive surface inside.

[0004]

[Problems to be solved by the invention]

 Originally, it is difficult for the adhesive to adhere to the surface of polyethylene. However, if the roll is made into a roll of 10 to 20 meters as described above, linear pressure is applied to the surface of the polyethylene, and the adhesive is adhered to the surface of the polyethylene. The agent is transferred and becomes difficult to peel off, making it unsuitable as a dust removal roll. Therefore, as described above, in the conventional product, it was necessary to coat the surface of the polyethylene with silicon resin or silicone oil by post-processing to improve the peelability of the adhesive. Therefore, the present invention aims to provide a more economical adhesive dust removing roll by eliminating this trouble.

[0005]

[Means for Solving the Problems]

 That is, in the present invention, a long laminated film having a pressure-sensitive adhesive layer formed on the opposite surface of a back-coated paper coated on one side with polyethylene blended with a lubricant as a release surface is used, for example, with paper with the pressure-sensitive adhesive layer on the outside. An adhesive dust removal roll characterized by being wound around a core material such as a tube. The lubricant used in the present invention is preferably a fatty acid amide-based lubricant.

As described above, the adhesive dust removing roll according to the present invention physically removes the lubricant bleeding on the surface of the polyethylene resin due to poor compatibility between the lubricant blended with the polyethylene resin and the polyethylene resin. It utilizes the effect and has a three-layer structure consisting of an adhesive layer, paper, and polyethylene resin. As with the conventional product, the surface of polyethylene is coated with silicone resin or silicone oil by post-processing, There is no need for a four-layer structure consisting of layers, paper, polyethylene resin, silicone resin or silicone oil layer.

[0007]

[Embodiment of the invention]

 FIG. 1 is a cross-sectional view showing the configuration of the adhesive film used for the adhesive dust removing roll according to the present invention. In FIG. 1, 2 is a substrate, 3 is a polyethylene blended with a lubricant, and 1 is an adhesive layer. The long film with this structure wound around the core member 5 of the patterned roll shown as an example in FIG. 2 with the adhesive surface 1 on the outside is the adhesive dust removing roll according to the present invention.

[0008] As the base material of the adhesive film used in the adhesive dust removing roll according to the present invention, various papers used in the conventional adhesive roll can be used. Examples of various papers include kraft paper, high-quality paper, pure white paper, medium-quality paper, roll paper, art paper, paper-change, cardboard, Kent paper, parchment, and the like. Above all, high quality paper and pure white paper are generally used as polyethylene processed paper. As the polyethylene resin for back-coating the paper, either high-density polyethylene or low-density polyethylene (such as LLDPE) can be used, but rather high-density polyethylene is preferred.

[0009] Lubricants to be blended with the polyethylene resin include hydrocarbons such as liquid paraffin, higher fatty acids such as distilled stearic acid, fatty acid amides such as stearamide, palmitic amide and erucamide, butyl stearate, Ester-based compounds such as ethyl palmitate and other various compounds may be used, and fatty acid amides are preferred in the present invention.

Examples of the fatty acid amide-based lubricant include commercially available products such as “Amide AP-1” (stearic acid amide 70 + palmitic acid amide 30 [Nippon Hydrogen Industry]) and “Diamid L-200” (erucic acid amide [ Nippon Hydrogen Industry], “Amide-E” (erucamide (Nitto Chemical Industry)), “Amide-O” (oleic amide 91 + stearic amide 6 + linolenic amide 3 (Lion Armor)), “Alpha -P-10 "(erucamide (Nippon Oil & Fats Co., Ltd.)) and the like.

The polyethylene resin film blended with the lubricant used in the present invention can be molded while simultaneously blending the lubricant when the polyethylene resin film is extruded and molded with a film T-die. The blending ratio of the lubricant is in the range of 0.5 to 5.0% (weight) with respect to the polyethylene resin. If the proportion of the lubricant is less than 0.5%, the releasing effect due to the bleeding of the lubricant is reduced, and if it exceeds 5.0%, the bleed lubricant transfers to the adhesive and deteriorates the adhesiveness, which is not preferable. . When erucamide such as "Diamid L-200" (Nippon Hydrogen Industry), "Amide-E" (Nitto Chemical Industry), "Alpha-P-10" (Nippon Yushi Kogyo) or the like is used as a lubricant. About 0.5 to 1.5% is preferable.

As the pressure-sensitive adhesive, a pressure-sensitive adhesive that is conventionally used for a pressure-sensitive adhesive dust removal roll may be used. That is, it is a generally used rubber-based hot-melt (hot-melt) pressure-sensitive adhesive.

[0013]

【Example】

 Embodiment 1 FIG. When extruding and molding a high-density polyethylene resin film with a T-die for film, molding was performed while simultaneously blending "Diamid L-200" = erucamide, a main component (Nippon Hydrogen Industries), as a lubricant. At this time, the blending ratio of the lubricant was 1.0% (weight) with respect to the polyethylene resin. An adhesive layer was formed on the opposite surface of the obtained long film, and the laminated film was wound around a paper tube with the adhesive layer facing outward to form an adhesive dust removing roll. The release effect of this adhesive rubbing roll was comparable to that of the conventional silicone resin or silicone wax coated by the bleeding of the lubricant blended with the polyethylene resin.

Embodiment 2 Adhesive dust removal was carried out in the same manner as in Example 1 except that "Amide AP-1" = stearic amide 70 + palmitic amide 30 (Nippon Hydrogen Industries) was used as a lubricant at 1.5% (by weight) based on polyethylene resin. As a result of producing the roll, the same release effect as in Example 1 was obtained.

[0015]

[Effect of the invention]

 Since the adhesive dust removing roll according to the present invention has the above-described configuration, it is difficult to perform post-processing by applying a silicone resin or silicone oil as a release agent to the polyethylene surface of the polyethylene back-coated paper as in the conventional product. Therefore, it is possible to provide an economically excellent adhesive dust removing roll.
