Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fitting material provided with a paper adhering surface for adhering paper such as shoji paper to an aluminum profile.

[0002]

2. Description of the Related Art Conventionally, there has been a tendency to use an aluminum alloy frame as a frame material for indoor fittings. However, even if shoji paper is pasted on the aluminum alloy frame material with starch paste, the glue will form a frame material. There is a problem that the paper does not penetrate and peels off in a wet state. Therefore, the pretreatment is performed with a paint or an adhesive using an organic solvent.

On the other hand, in recent years, it has been desired to improve the pollution of the indoor environment and the working environment, and the use of the organic solvent is being regulated, so that the organic solvent cannot be used easily.

[0004]

SUMMARY OF THE INVENTION In view of the above points, the present invention has an object to develop a fitting material capable of sticking shoji paper on an aluminum surface by using a treating agent containing no organic solvent. .

[0005]

According to the first aspect of the present invention, a water-soluble emulsion containing an acrylic resin as a main component is mixed with magnesium carbonate to form a coating layer formed on an aluminum profile. If the fitting material provided on the paper sticking surface of the above is used, the shoji paper can be easily stuck to the aluminum profile with ordinary starch paste, and the replacement can be easily performed so that it does not come off for a long time. can do. Further, since no organic solvent such as toluene or n-butanol is used, contamination of the working environment can be prevented, the environment is friendly, and the human body can be processed safely.

The mixing ratio of magnesium carbonate does not matter, but if it is less than 5 parts by weight, the starch paste cannot be applied to the aluminum profile, and if it exceeds 20 parts by weight, the viscosity of the emulsion is lowered and the aluminum profile is reduced. 5 to 20 parts by weight is desirable because it is difficult to process into.

According to a second aspect of the present invention, a water-soluble emulsion containing a urethane resin as a main component is provided with a coating layer formed of a treating agent in which magnesium carbonate is mixed, on the surface of the aluminum profile paper to be adhered. In the case of a fitting material that has been used, shoji paper can be easily attached to an aluminum profile with a common starch paste, and the attachment can be easily replaced so that it will not come off for a long period of time. Further, since no organic solvent such as toluene or n-butanol is used, contamination of the working environment can be prevented, the environment is friendly, and the human body can be processed safely.

[0008] In the invention according to claim 3 of the present invention, magnesium carbonate is more effective when used as a fitting material which is a treating agent in an amount of 5 to 20 parts by weight with respect to 100 parts by weight of the water-soluble emulsion. The shoji paper can be attached to the paper, it can be easily replaced, and it can be maintained without peeling for a long time.

According to the fourth aspect of the present invention, the aluminum profile is a fabric material or a fitting material which is an alumite treatment material, so that the treatment agent can be applied more easily and effectively. it can.

The acrylic resin may be any, but for example, polymers such as acrylic acid ester, methacrylic acid ester and acrylonitrile, that is, polyacrylic acid ester, polymethacrylic acid ester, vinyl acetate, styrene, vinyl ether, etc. are typical. Examples thereof include non-acrylic copolymers and the like. Urethane resin is not limited, but for example, water-based urethane paint,
A water-based urethane adhesive is mentioned, and a curing agent needs to be added to the water-based urethane adhesive. The curing agent is not limited, but isocyanate is preferable. Magnesium carbonate can be used, but in order to process the treated surface into a smooth surface,
The particle size is preferably 75 μm or less. In addition, it is preferable to add a dispersant for improving work efficiency and quality control. The dispersant is not limited, and examples thereof include sodium polyacrylate and acrylic acid ester copolymer. Further, a pigment may be appropriately added if necessary.

As the treating agent, for example, 5 to 20 parts by weight of magnesium carbonate (particle diameter of 75 μm or less is 99% or more) is mixed with 5 to 20 parts by weight of the acrylic resin water-soluble emulsion or urethane resin water-soluble emulsion. Can be obtained by In the case of urethane resin adhesive emulsion, with respect to 100 parts by weight of the emulsion,
It is desirable to mix 5 parts by weight of the curing agent. It should be noted that the mixing can be easily performed by using a paint roll or the like that can be mixed by applying a shearing force so that the magnesium carbonate is sufficiently dispersed during the mixing. Further, water is appropriately added for viscosity adjustment, and a pigment is appropriately added for coloring. Next, the obtained treating agent, aluminum dough material or anodized aluminum material, curtain flow coater, roll coater or by spraying or the like, the paper stuck surface by applying 30g / m ² ~100g / m ² formed directly To do.

Paper such as shoji paper can be pasted by directly applying starch paste to the fitting material having the paper pasting surface on the paper pasting surface. Regardless of the paper to be stuck, various shoji papers such as shoji paper, manila hemp, rayon, vinylon, pulp-containing shoji paper, and plastic adhesive shoji paper can be used.

EXAMPLES The present invention will be described in detail below based on examples. The present invention is not limited to these examples.

Table 1 shows the formulation of the aluminum profile treating agent according to the present invention. Examples 1, 2, 3, 4, 5 are formulations in which an aqueous urethane coating and 5 to 25 parts by weight of magnesium carbonate are added, and Examples 6 and 7 are formulations in which an aqueous urethane adhesive and 10 or 20 parts by weight of magnesium carbonate are added. Comparative Examples 1 and 2 are formulations containing no magnesium carbonate. The water-based urethane paint is Aqualetan 625 manufactured by Kansai Paint Co., Ltd., the water-based urethane adhesive is JW-6430 manufactured by Nippon Fuller Co., magnesium carbonate is light magnesium carbonate manufactured by Kyowa Chemical Industry Co., Ltd., and the dispersant is manufactured by Toagosei Co., Ltd. A-6330 (sodium acrylate maleic acid copolymer), titanium oxide commercially available as a reagent, and HFB-70 (aliphatic polyisocyanate) manufactured by Nippon Fuller Co., Ltd. were used as a curing agent.

[Table 1]

Table 2 shows the results of comprehensive judgment of the stability of the treating agent, the coating property on the aluminum profile, the adhesion with the aluminum profile, the adhesive property of the shoji paper, and the resistance to moist heat. The adhesiveness with the aluminum profile is as follows: after coating the aluminum profile with a treatment agent and drying, 100 squares are engraved in a 1 cm square of the sample surface, and adhesive tape is applied to it to remove it. A test for examining the subsequent surface condition was conducted, and 100/100 means that the coating film was not peeled out of 100 squares. When the blending ratio of magnesium carbonate was 20 parts by weight as in Example 4, the paintability was slightly deteriorated, and when it was 25 parts by weight as in Example 5, the paintability was poor and the shoji paper did not adhere. From this, it was considered that 5 to 20 parts by weight of magnesium carbonate is desirable. Further, as in the case of Examples 6 and 7, the water-based urethane adhesives also had very good shoji paper adhesiveness by incorporating a curing agent. With the formulations containing no magnesium carbonate as in Comparative Examples 1 and 2, the shoji paper adhesion was extremely poor.
