Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an aluminum sash repair material for filling and repairing surface scratches on an aluminum sash.

Since aluminum sashes are essentially made of aluminum itself, they are extremely susceptible to scratches.

For this reason, various methods are used to harden the surface or form a protective film on the surface, but since the product is long, the surface may be It is not possible to prevent scratches to a large or small extent from occurring on the surface of the surface of the surface of the surface of the surface of the surface of the surface of the surface of the surface of the surface of the surface of the surface of the surface of the surface of the surface.

In the case of colored aluminum sashes, which have become increasingly popular these days, the surface scratches are even more noticeable, and as a countermeasure to this problem, a method is used to fill the surface scratches with putty, let it dry, and then apply a paint of the same color on top of it. ing.

However, such work wastes labor and time, increases costs, and poses a major problem in terms of profit and profit.

In view of this situation, the inventors of the present invention have conducted various tests and researches, and have found that a solid type product that can perform the steps of filling with putty, drying, applying paint, and drying in one step required by conventional repair methods. A repair material can be obtained, and the present invention is provided based on this.

The aluminum sash repair material of the present invention is a mixture of sticky wax, resin, and a coloring material that is the same color as the aluminum sash to be coated, and can be applied simply by filling it into the scratches on the surface of the aluminum sash. This makes it possible to repair scars with simple work.

Examples of the present invention will be described in detail below.

The aluminum sash repair material of the present invention is a mixture of adhesive wax, natural or synthetic resin, and a coloring material of the same color as the aluminum sash to be coated.The wax, resin, and coloring material are as follows. It is.

(1) Wax In order to fill the surface scratches of the aluminum sash with mineral, animal, or vegetable wax, microcrystalline wax, beeswax, wooden wax, etc., which have sticky properties, are used.

It is also desirable to add a portion of carnauba wax, candelilla wax, montan wax, etc., which becomes glossy when lightly rubbed after application.

The blending ratio of wax is preferably within the range of 25 to 50%, most preferably 40 to 50%.

(2) Resin This resin is used in combination with the wax to further strengthen its adhesiveness, and must be compatible with the wax used.

Rosin, terpene resin, petroleum resin, coumaron resin, etc. are used as resins that satisfy this requirement.

The blending ratio of the resin is desirably within the range of 5 to 20%; if the blending ratio is too high, the writing quality of the repair agent will be impaired and the ability to fill scars will be deteriorated.

The most desirable blending ratio is around 10%, and the total amount of wax and resin is preferably 40 to 60%.

(3) Coloring material The same color as the aluminum sash to be repaired. For example, use aluminum powder for silver-colored aluminum sashes, use aluminum powder and bronze powder for gold-colored aluminum sashes, and use amber color. In the case of aluminum sashes, aluminum powder, bronze powder and black pigment (
Carbon black, iron black) is used.

The blending ratio of the colorant is preferably within the range of 20 to 30%.

To produce the repair material of the present invention from such wax, resin, and coloring material, the wax and resin are first melted in a mixer equipped with a heating stirring device such as a heating furnace, and then the coloring material is added and the mixture is sufficiently heated. Stir.

In this case, in order to adjust the viscosity during molding, a suitable filler material such as talc, calcium carbonate, precipitated barium sulfate, etc. may be added.

After stirring, this mixture is sufficiently kneaded with a roll or the like and molded into the desired shape and dimensions.

Next, test examples regarding aluminum sashes in three colors: silver, gold, and amber will be explained.

Example of blending wax, resin, and coloring material in each test example (
weight%) are as shown in the table below.

Microcrystalline wax, which is a wax,
Beeswax, montan wax, carbana wax and terpene resin are heated and melted at 100 to 120°C in a heated seconder according to each formulation example, and aluminum powder as a coloring agent and aluminum powder are added to the mixture according to each formulation. Bronze powder or carbon blank, talc as a filler material, and precipitated barium sulfate are added and stirred thoroughly.

Next, these ingredients are taken out, kneaded several times using two rolls, and then cooled to room temperature.

Next, each cooled material is placed in an extruder with a diameter of 11 to 1
It was extruded into a 2 mm hexagonal rod shape and formed into a stick shape with a total length of 100 mm.

Cut the tip of each repair material into a conical shape and apply it to the surface scratches of each silver, gold, and amber aluminum sash so that it is well filled, and wipe off the part of the repair material that protrudes from the scratches with soft paper. Completed the repair.

As a result of cycle tests of aluminum sashes of various colors repaired with the repair material of the present invention under conditions of temperature -5°C to 40°C and humidity 30 to 90% RH, changes such as falling off of the repair material and discoloration were observed. It has been found that it can withstand a very long period of time.

As is clear from the above, according to the present invention, the scratches on the surface of an aluminum sash can be repaired in a way that makes them inconspicuous by the simple operation of filling the scratches on the surface of the aluminum sash. transportation personnel,
Any aluminum sash dealer or aluminum sash installer can repair the damage.

The aluminum sash repair material of the present invention has enhanced adhesion due to the compatibility of wax and resin, and has a strong adhesion to aluminum sashes and a great repair effect. Since no repair material is used at all and it consists of 100% solids, there is no shrinkage of the applied repair material and the finish is good, and there is no environmental pollution caused by organic solvents.

In addition, the aluminum sash can be coated for a long period of time to prevent corrosion of the aluminum sash, and the cost of the aluminum sash can be reduced.

Claims (1)

[Claims] 1. Mix adhesive wax, a resin compatible with wax to strengthen the adhesiveness of the wax, and a coloring material of the same color as the aluminum sash to be coated without using an organic solvent, Kneaded and molded aluminum sash repair material.
