Problems solved by technology

However, in the above-mentioned solvent-based normal temperature curing repairing agent, the volatilized solvent odor is not only annoying during curing, but also has problems in terms of safety and sanitation due to the volatilization of the solvent.
In addition, it takes time to achieve drying and curing. In addition, as the solvent in the repairing agent volatilizes with drying and curing, the repaired part (formed body, thickened part) is easy to shrink and deform (be thinner). In one repair operation, it cannot Repair (restore) to desired shape, there is a problem that the repair operation must be repeated

manufacture example 1

[0095] Production Example 1: Production of a prepolymer containing terminal NCO

[0096] In the presence of tin octoate, 73.9 parts by weight of polypropylene ether triol (polypropylene ether triol) with an average molecular weight of 7000, 14.6 parts by weight of polypropylene ether diol (polypropylene ether diol) with an average molecular weight of 3000 and 12.5 parts by weight of 4,4'-Diphenylmethane diisocyanate was reacted at 80°C for about 2 hours to obtain a terminal NCO-containing prepolymer with a terminal NCO content of 3.07% and a viscosity of 30,000 cps / 20°C.

manufacture example 2

[0097] Production example 2: Production of latent curing agent (powder coating amine)

[0098] Mix 76.9 parts by weight of 1,12-dodecanediamine (melting point 71°C) with a central particle diameter of about 8 μm and 23.1 parts by weight of ultrafine titanium oxide with a central particle diameter of about 0.02 μm, and mix in Hi-X Compounding treatment was performed in a machine (manufactured by Nisshin Engineering Co., Ltd.), thereby obtaining 100 parts by weight of powder coating amine with a central particle diameter of about 8 μm.

manufacture example 3

[0099] Production Example 3: Production of one-component heat-curable composition

[0100] With a pressure-resistant explosion-proof mixer (chemista-la), make the prepolymer 41.5 parts by weight of the terminal NCO, the polyisocyanate compound (former MDI) 15.4 parts by weight of the manufacture example 1, the latent curing agent (powder) of the manufacture example 2 10.5 parts by weight of body coating amine), 23.1 parts by weight of black toner, and 9.5 parts by weight of filler (ground calcium carbonate) were mixed and dispersed to obtain a one-component heat-curable composition.

Abstract

A shoe bottom repair agent for mending a shoe sole or heel that is free from solvent evaporation problems, and that can be cured within a short period of time, substantially free from any deformation shrinkage accompanying the curing, and that realizes repair to a desired shape through one-time repair work. There is provided a shoe bottom repair agent consisting of a one-component thermosetting composition comprising as main ingredients a terminal isocyanate having urethane prepolymer and / or a polyisocyanate compound and a latent curing agent. This shoe bottom repair agent is free from, experienced in the use of solvent base shoe bottom repair agents, safety and sanitation problems such as odor and inflammation by solvent evaporated at the time of curing as well as cured matter thickness reduction of a mended part caused by solvent evaporation. With the use of this shoe bottom repair agent, damaged shoe bottom portion can be mended to a desired shape through one-time repair work. Short-time curing can be effected by heating. Further, before heating, there is substantially no viscosity increase and no surface film is formed to thereby avoid adhesion of a film resulting from surface drying to a spatula. Therefore, the repair surface can be finished smoothly and neatly.

Description

technical field [0001] The present invention relates to a shoe sole repair agent for repairing worn parts, damaged parts, missing parts, etc. of soles and heels of shoes, and a shoe sole repair kit using the shoe sole repair agent. Background technique [0002] As a method of repairing shoe soles, a method of repairing by adhering a crescent-shaped or semicircular rubber plate that becomes thicker toward the outer peripheral side with an adhesive to the heel portion of the shoe sole is widely used. However, the wear of the heel portion varies depending on the walking posture and the usage time of the shoes. Therefore, there is a problem that the sole cannot be repaired to an optimal state with respect to the finished rubber plate of the same shape. [0003] Therefore, recently, as a method of repairing the sole, mainly the heel part, it has been proposed to install a mold frame (take a mold plate) around the heel, inject a two-component reaction type such as epoxy resin, pol...
