JPS60120770A - Production of colored putty for repair of wood - Google Patents

Abstract

PURPOSE:To obtain a putty having the desired color by simple in situ mixing, by mixing a main epoxy putty component with a hardener in a specified ratio and mixing the resulting mixture with woodmeal, which is colord so as to give standard wooden color, in a quantity giving the desired degree of coloration. CONSTITUTION:A container contg. a main epoxy putty component and a container contg. a hardener are opened and they are mixed in equal quantities or in quantities specified by makers. The mixture is thoroughly kneaded. During kneading, there is mixed woodmeal which is colored so that the putty is colored to standard wooden color. The colored woodmeal is used in a quantity giving a colored putty having the desired degree of coloration. The putty can be used for dovetail joint of wood, doweling, repair which enables nails to be hammered into the edge of particle board and for filling and bonding dead knots and cracks.

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 processing, dowel processing, reinforcement to enable driving of nails into the end surface of particle board, row parts,
The present invention relates to a method for producing a colored putty for repairing wood, which can be used for crack-filling, structural adhesion, etc. (hereinafter also simply referred to as array patching, etc.).

Conventionally used wood repair putty (for example, putty with the trade name Evostick) is made by mixing a hardening agent with an epoxy base ingredient to create a putty.

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 encapsulated.

Therefore, the present invention provides an opportunity for amateurs such as carpenters to mix the main ingredient and hardening agent to produce wood putty.
A colored putty for wood repair that simultaneously provides a means of increasing the amount by mixing wood flour and a means of matching the color tone of the colored putty to the target wood, and also allows the product to be easily obtained without inclusions. The aim is to provide a manufacturing method for this.

Examples will be described below. First, it is kneaded to make it known to the general public. 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 a repair hole, it hardens in 2 hours, reaches practical hardness after 5 hours, and is completely hardened after 24 hours. Once cured, it can be processed in the same way as wood.

Next, the above-mentioned means for coloring wood flour is such that the wood flour can be uniformly colored very easily by simply adding a linear dye or pigment to the wood flour and mixing it as desired. In this case, even if the wood powder is fine, even large wood powder such as that produced in a small sawmill can easily be colored. If the base agent or curing agent is colored, the coloring density of the wood flour should be made a little thinner considering the degree of coloring.
Also, if you want to reduce the amount, 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 that the missing parts can be captured and the quality of the wood can be improved. Of course, the area 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 immediately after mixing, making it easy to work with, but after filling, the meat does not become thin.
Furthermore, after hardening, it exhibits properties similar to those of wood, making it possible to process it with a saw or plane. 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 colored putty can be produced by simply mixing the main ingredient, hardening agent, and wood flour in a predetermined amount. Another feature is that, for example, a carpenter at a construction site can easily produce the small amount of colored putty he or she needs and use it immediately. In this case, even if the target wood has a dark tone, it is possible to darken the color of the unevenly colored putty by simply adding and mixing wood powder one after another to match the target wood's tone. There are also some really useful color adjustment effects.

Claims (1)

[Claims] Prepare the main ingredient of epoxy putty, hardening agent, and wood powder.
Moreover, the wood flour is colored in advance so that when the main ingredient, hardening agent, and wood flour are mixed in the predetermined amounts, the color of the putty formed by the mixing becomes a standard wood color. When mixing these three components, the base agent and hardening agent are selected in a predetermined proportion, while the amount of wood flour is adjusted to match the degree of coloring of the colored putty to be inserted. 1. A method for producing colored putty for wood repair, which comprises selecting a putty and producing a putty having a degree of coloring that meets a request.
