Description

[Detailed Description of the Invention] This invention relates to a putty for woodworking, and more specifically, it is used for array stripping of wood, core stripping, doweling, reinforcement to enable driving of nails into the end face of particle board, and dead joints. , crack filling structure adhesion, etc. (hereinafter also simply referred to as array stripping, etc.)
This article relates to a method for repairing wood that can be used for.

Traditionally used putty for wood repair (for example, the putty with the trade name Epostastek) is made by mixing a hardening agent with an epoxy base ingredient and making a putty.
I was taking advantage of this. However, since this does not match the color tone with the wood, attempts have been made to supplement the putty with coloring agents (for example small amounts of pigments or dyes). This trial method had the disadvantage that the amount of coloring agent used was extremely small compared to the total amount of putty, which resulted in uneven mixing, making it impossible for on-site carpenters to easily mix and obtain colored putty in the desired color. .

On the other hand, it has been considered to add wood flour to the colored putty to increase its weight, but when wood flour is added, the coloring agent gets into the wood flour and the colored putty becomes more and more unevenly colored.

Therefore, the present invention provides a method for increasing the amount of wood putty by mixing wood flour when an amateur such as a carpenter mixes a base agent and a hardening agent to produce wood putty at the site.
To provide a method for simultaneously obtaining a means for matching the color tone of a colored putty to the target wood, easily obtaining a product without color spots, and performing high-quality repair.

Examples will be described below. First, as is generally known, open the package of the putty-like base ingredient and hardening agent, and cut out the required amount into equal amounts (or amounts according to the manufacturer's specified ratio). Next, knead these well.
Prior to or during this kneading, colored wood flour is mixed in (the amount is approximately equal to the base ingredient). When the kneading is finished, the desired colored putty has been produced. This colored putty can be used in the same way as general woodworking putty. For example, after filling the repair hole,
It hardens in 2 hours, reaches practical hardness after 5 hours, and is 24
It will harden completely after some time. Once cured, it can be processed in the same way as wood.

Next, as for the method for coloring the wood flour, the wood flour can be uniformly colored very easily by simply adding a paste of dye or pigment to the wood flour and mixing the mixture as desired. The wood in this case is easily colored even by fine particles or large wood particles such as those produced in sawmills. If the base resin or hardener is colored, the coloring density of the wood flour should be made slightly thinner considering the degree of coloring, and if the mixing ratio of the base resin and hardener is to be larger than the equal amounts of each, adjust the coloring density in advance. It is best to keep it thin. If you want to reduce the mixing ratio of wood flour, it is better to make the color darker.

As described above, in the present invention, colored putty is prepared by mixing the main ingredient of epoxy putty, a hardening agent, and wood flour. This has the advantage of making it possible to fill in the missing parts and improve the quality of the wood. Of course, the part filled with the above-mentioned colored putty has the advantage that the color tone corresponds to the color tone of the wood due to the presence of the colored wood flour. In addition, it is malleable and easy to work with immediately after mixing, but there is no thinning after filling, and after hardening, it exhibits properties similar to wood, making it possible to process with saws and hooks. . It also has the advantage of discoloring over time, just like wood.

Furthermore, according to the present invention, since the wood flour acts as an extender, there is an economical effect that a large amount of colored putty can be produced with a small amount of base ingredient and hardening agent.

Furthermore, according to the present invention, the wood flour is colored in advance, and the production of the colored putty simply involves adding a main ingredient, a hardening agent, and
This can be done simply by mixing a predetermined amount of wood flour, so for example, a carpenter at a construction site can easily produce a small amount of colored putty and use it immediately. There are some features that can be used. In this case, even if the color of the wood to be repaired is dark (light), in the method of the present invention, the color of the wood powder is different from the color of the putty created by mixing the base resin and hardening agent. Considering the different characteristics and the fact that the wood flour is added before curing, it is possible to simply add wood flour one after another and mix it into the above-mentioned soft putty to match the color tone of the wood to be repaired. This has the effect of color adjustment work, where you can gradually deepen (lighten) the color tone of the colored putty without spotting, and change the color of the putty so that it approaches the color of the corresponding wood. It is extremely useful for carpenters to use.

Claims (1)

[Claims] 1 Wood flour to be mixed into the putty made by mixing the main ingredient of an epoxy putty, a hardening agent, and the above-mentioned main ingredient and hardening agent in a predetermined amount, and by mixing the wood flour. In order to adjust the color of the putty to the standard wood color, prepare in advance wood powder colored in a dark or light color that is different from the color of the putty, and when repairing wood, use the main agent and , and a hardening agent in the amount necessary for repair in a predetermined ratio, and before the putty hardens, the wood powder is added to the putty so that the color of the putty changes according to the color intensity of the repaired area. This method of repairing wood is characterized by adding only the required amount to change the color of putty to a degree of color matching that of the repaired area, and adhering the putty to the repaired area of the wood before hardening and curing there.
