JPS61163976A - Gold bronze powder paint - Google Patents

Abstract

PURPOSE:To enable pure gold decorations to be prepd. by a simple method without particular limitation to materials to be used, by using a paint obtd. by dispersing gold bronze powder in lacquer consisting of a special fluororesin and celluloses. CONSTITUTION:Gold bronze powder is dispersed in lacquer consisting of a special fluororesin contg. hydroxyl and carboxyl groups and celluloses. Examples of the celluloses are ethylcellulose and cellulose acetate butyrate. Particularly, ethylcellulose having an ethoxy content of 48-49.5% and cellulose acetate butyrate having an acetyl content of 2.0-2.8%, a butyryl content of 50-53% and a hydroxy content of 1.5-1.8% are preferred.

Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a gold powder paint that can be used for decorating the surface of metal products with gold powder, for writing patterns and letters on lacquerware, and as pure gold manicure.

(Prior Art) Conventionally, the surface of metal products has been decorated with gold leaf or plating. Another 1! ! As for the kind.

There was a method of writing on finely ground gold powder with glue and writing on it with a brush, or a method of writing with patterns, in which a pattern was drawn in advance with lacquer and then sprinkled with gold powder to create the pattern.

(Problems to be solved by the invention) In traditional technology, processing techniques differ depending on the characteristics of the material, and there was no simple pure gold decoration technique that could be applied to any material. Further, in particular, the technique of writing patterns on lacquerware with single letters does not necessarily allow the gold powder to be stably fixed on the object to be decorated, and there is a problem in that the gold powder deteriorates over a long period of time.

(A child actor for solving the problem) The present invention uses a gold powder paint containing a gold powder paint mixed with a special fluorocarbon resin having a hydroxyl group and a carboxyl group in one molecule and a lli element. This solves the problems mentioned above.

In other words, fluorocarbon resins generally lack gloss, are opaque, have poor adhesion, and often require high-temperature baking;
A fluorinated resin was invented that is a copolymer of fluorinated ethylene, cyclohexyl vinyl ether, and vinyl nitrates having hydroxyl and carboxyl groups, and is transparent and glossy, can be cured at room temperature, and has excellent light resistance.
44083) By adding cellulose to the right fluorine resin, it dries at room temperature, is light stable, transparent, and glossy, and is also excellent against copper, brass, aluminum, stainless steel, wood, etc. A clear lacquer with excellent adhesion was invented (Japanese Patent Application Laid-open No. 43068/1983).

One of the present inventions is that gold powder is blended with this lacquer clear to create a gold powder paint.

Note that examples of cellulose that can be made into lacquer include ethyl cellulose and cellulose acetate phthalate.

In particular, ethyl cellulose has an ethoxy content of 48 to 49.5.
%, suitable cellulose acetate butyrate has an acetyl content of 2.0 to 2.8%, a butyl content of 50 to 53%, and a hydroxyl content of 1.5 to 1.8% (Example) 1) Fluorine resin for special paints with hydroxyl and carboxyl groups in the molecule (Lumiflon LF40 manufactured by Asahi Glass Co., Ltd.)
0) 100 parts, cellulose acetate butyrate (EAB551-0 manufactured by East Yan Yudak Co., Ltd.) as a cellulose
．． 2) Mix and dissolve 50 parts of butyl acetate as a solvent to make a transparent lacquer clear. I! 100 parts of this rough car clear along with 1 part of additives! Place it in a rustic mortar, add 10 parts of gold powder, and grind it thoroughly with a pestle to make gold powder paint.

In addition, it is used after being diluted with a solvent such as butyl acetate or ethyl acetate at the time of application.

(2) Right: To give an example of painting with gold powder paint, after thoroughly washing the surface of a brass product, dilute the gold powder paint with a solvent, apply it to one surface with a brush, etc., and dry. To make the surface more glossy, it is recommended to apply a gold powder paint, then dilute a lacquer clear consisting of a special fluorocarbon resin and cellulose 2 to 3 times with a lattice paint, and apply with air spray.

(effect) The effects of the present invention are as follows.

(+) It has become possible to manufacture pure gold*m products using a simple method without having to select H materials.

(2) The gold powder can be stably fixed on the object to be decorated, and since the gold powder itself is used to the 7-Fun resin, it does not change in quality even after a long period of time.

Claims (1)

[Claims] A gold powder paint in which gold powder is mixed and dispersed in a lacquer made of a special fluorocarbon resin that has hydroxyl and carboxyl groups in its molecules and cellulose.
