術上の諸問題に対処する。[Industrial Field of Application] The present invention can be applied to a variety of applications such as repair work for external walls and repair and reinforcement work for concrete structures. This occurs due to excessive injection of epoxy resin, injection leakage, dripping, etc. The present invention relates to a construction method and an epoxy remover for efficiently removing resin contaminated by adhesion or adhesion of epoxy resin to other objects. In addition, epoxy resins are widely used not only in the construction industry, but also in civil engineering, the aircraft industry, the shipping industry, etc., as adhesives and coating agents, and address various problems in repair technology.

ら、講じられていない。[Prior Art] Conventionally, when epoxy resin has hardened and adhered, it has been removed by damaging the material by scraping it off with physical force due to its strong adhesive force. Due to aging, it becomes yellowed and contaminated, which is often seen as an undesirable result of construction work, especially in terms of maintenance of preserved buildings. Furthermore, during chemical anchor construction, dams, bridge piers, etc., and tunnel construction, the surrounding areas are unsightly due to leakage and outflow of epoxy resin, and no technical measures have been taken to remove the leakage.

500 cc was mixed into 10 liters of the composition of 2). We developed a method for removing epoxy resin by wiping the epoxy resin-adhered surface after the heat treatment process with a cloth impregnated with the solution of the present invention using a solution composed of the above-mentioned mixture balance.

Apply it for 7 seconds, then peel off the softened epoxy resin using a jig such as a leather scraper. After that, the remaining epoxy resin can be completely removed by impregnating the solution of the present invention with a cloth or cloth.

(1) The above effect is an example of the epoxy resin removal work carried out during the renovation work of NTT Kanazawa Hospital in Kanazawa City, Ishikawa Prefecture (completed in February and March 2016), and even after one year has passed, there is still discoloration and fading in the surrounding area where it was removed. There are no such situations. (2) In early April of H2, stainless steel fittings were attached to chemical anchors (
During the installation work (stainless steel SUS304 anchor with epoxy resin encapsulated in it), epoxy resin leaked when inserting the anchor. After 17 hours, remove it by following the process described above. It has already been more than 360 days since the removal work, and the results are good, with no discoloration, fading, or yellowing, despite the fine irregularities in the stone. (3) Experimental materials Ina Seito semi-magnetic tile, Kanebo NSC epoxy resin KBKE615 Part A: Part B Mixing ratio A:B = 2:1 Tile with the above epoxy resin A:B = 2:1 specified ratio After mixing, stirring, and applying, a removal test was attempted after 43 hours. A moist air blower blows hot air at about 85°C onto the epoxy resin-coated surface of the tile of the test piece, and after 6 seconds, the resin surface is removed with a skin plow or the like, and then wiped off with work gloves impregnated with the solution of the present invention. Completed in just 1 minute. The construction m2 was 0.2 m2.
