Abstract

PURPOSE:To obtain an artificially patinated embossed roofing material having a bluish-green fine appearance by treating the surface of a sulfurized embossed copper roofing material with a mixed aqueous soln. contg. chemicals for corroding copper sulfide and a patina forming agent. CONSTITUTION:The finely uneven surface 3 of an embossed copper roofing material 2 is blackened by sulfurization, and the blackened surface is coated with a mixed aqueous soln. 5 contg. chemicals consisting of copper nitrate and sodium chloride for corroding copper sulfide 4 and a patina forming agent such as NH4Cl. The copper sulfide 4 is corroded with the chemicals and peeled, and the patina forming agent forms artificial patina 8 on the copper surface. The surface of the material 2 is then coated with acrylic clear laquer as usual so as to prevent the peeling of the patina 8. Thus, the desired artificially patinated embossed roofing material is obtd.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to the four methods of roofing materials, which are artificial roofing materials having a suspicious appearance.

[Seishun technique]

Since then, green lF has been artificially generated on the surface of the rope boards, and artificial roofing materials have been used for 4!8! To do this, the shrine roofing material is immersed in backwater such as salt water, water, etc., then pulled up, drained of the liquid, dried indoors, and artificially grown. , Table 1 Method of manufacturing by painting clear on the surface of the roof, or after spraying copper roofing material VC green g liquid in dots, drying to generate an artificial stain on the surface, and then painting with clear. The method of doing so is helpful. However, the former method suffers from artificial patina on the entire surface of the soil and the natural patina. -A10, which has a black and white color like the one shown in the picture above, cannot be rinsed, and when using the latter method, artificial spots such as ',', and 'A' are deposited on the copper color. C
It looked like a snake, but it was unnatural and a far cry from its natural green color.

[Purpose of the invention]

The present invention has been made in view of the above points, and is similar to natural greenery.1. The object of the present invention is to provide a method for producing rainbow-like artificial greenery + R41 bamboo material that can be used for one song and one shift.

[Disclosure of 1 pJ of light] In other words, the method for manufacturing the Nijiposu roofing material of the present invention includes sulfurizing the surface of the Nijiposu roofing material in which unevenness is not formed on the surface. This sulfurization treatment is 1tZc! 1
1a store 4 was removed, 2) for Table 1, a mixed aqueous solution of a drug that traces 1 accent ratio (4) and a nuisance generating agent (5) complete treatment, and sulfurization. Where Jlj r! ! The sulfurized steel (4) rots, rots and becomes rusty due to the accumulation of water-soluble insects (16) in the recesses (6) of the bean root material (2), and the steel roofing material (2). The convex part (7) is! Heart/Detection is low 3
The black part of the 41st part of the Nijiposu 6) is white and the black part of the convex part (7) of the 8th part of the Nijiposu part 6) is the black part of the 41st part of the Nijiposu. It has achieved k things.

Below 4. Yuan tsu 1 is shou, blood is 1 and 1 yen is described. The Nijipos net roofing material 2j has a pattern of unevenness: 3) shaped like 1 over the entire uir, and this Nijiposu net roofing material'2

Thereafter, the Nijipos steel roofing material (2) is pulled up from the liquid 15) and dried. At that time, in order to prevent the peeling of the artificial greenery W18) on the surface, a shield is applied to the surface of the roofing material (2), such as acrylic, uretashi, melasian, nitrocellulose, al + A rainbow-like artificial green roofing material is obtained by applying a clear coating such as a clear material such as a paint.

However, when the sulfurized copper roofing material (2) is immersed in the mixed aqueous solution (5), the copper sulfide (4) on the surface peels off into very fine dots, and the black copper sulfide 14) surface peels off. Fine dots of copper undercoat appear on the surface of the roof, which will be greened with the green W-generating solution. By using embossed steel roofing material (2) with unevenness (3) formed on the surface, The mixed aqueous solution (5) tends to accumulate in the fourth part 16), and the mixed aqueous solution g (

) occurs in the color group, but it does not occur much in the convex part (7), and in the fourth part (6)! Artificial rainbow-like green that approximates the natural green back where the white color and the black tone of the protrusions (7) harmonize well #
Roofing material can be obtained. In addition, since the surface is embossed, the artificial greenery (8) is difficult to peel off from the surface due to the anchoring effect due to the mechanical catch on the surface of the table [m]. Because the forest W(8) is generated, the artificial forest t18) part will not peel off due to friction etc. during transportation.

〔Effect of the invention〕

As described above, in the present invention, the surface of the embossed steel roofing material is sulfurized, and the surface of the sulfurized copper roofing material is treated with a mixed aqueous solution of a cross-linking agent and a green backing agent that corrode the sulfurized steel. The four parts of the emboss are specially treated with a mixed aqueous solution to form an artificial green back on the four parts, and the black color of sulfurized steel remains on the convex part, resulting in a natural color that harmonizes well with the bright white color of the concave part of the rainbow boss and the black of the convex part. It is possible to obtain a rainbow-like artificial patina roofing material that approximates the green fVc, and it is possible to reduce the product I[IfI direct by 1%.
