Description

  The present invention is an architectural composition applied to a wall or ceiling of a building, and an object of the present invention is to provide a coloring method for an architectural composition in which a colorful color is obtained in the composition.

Conventionally, finishing construction has been performed on the interior and exterior of a building by applying or spraying a composition obtained by mixing a cement-based material with a sand and other materials as a coating material (hereinafter collectively referred to as coating). ing. The cement-based material and sand are white or gray, and when used as they are, the color becomes surface, so that they are colored as necessary.
The above-mentioned coloring is mainly composed of cement, sand, etc., and if necessary, water retention agent, early strengthening agent, extender, thickener, antifreezing agent, antifoaming agent, antifungal agent, surfactant, etc. A small amount of admixture was added, and at the same time, a colorant was mixed, and they were stirred for a predetermined time to produce a coating material.

In addition, although organic materials and inorganic materials are used for the colorant, the organic materials contain volatile organic substances that are harmful to the human body, such as formalin. This causes factors such as sick house syndrome, and the internal and external environments are contaminated.
The amount of volatile organic substances has been reduced by dispersing the above organic substances in water and emulsifying or increasing the boiling point. However, they are limited and have reached an area that is harmless to the human body. Absent.
In addition, organic materials generally have a significant deterioration and have a drawback that the color fades early after construction.

On the other hand, the inorganic material has not been able to produce a coloring effect due to the particle size problem and the order and time of mixing and stirring.

Hereinafter, it explains in full detail based on an Example.

  Cement is known as a slaked lime-based material, but Portland cement, white cement, magnesia cement, mixed cement, and the like are employed as the cement that has been generally used. Preferably, slaked lime-based materials such as white cement, ordinary Portland cement or reinforced Portland cement are used.

  The slaked lime is usually referred to as lime, and is obtained by applying water to digested lime produced by baking limestone at about 900 to 1200 ° C. It is a white powder that is paste-like when kneaded with water, and when left standing, has the property of being changed to insoluble lime carbonate and cured by carbon dioxide in the atmosphere.

  The sand is river sand, mountain sand, washed sea sand, etc., and particularly porous sand is preferable. Moreover, the thing of the particle size of about 0.02 mm-0.2 mm is used.

As the inorganic colorant, additive pigments having a particle diameter of about 0.2 μm to 1.5 μm, such as triiron tetroxide and titanium oxide, are used.
By setting it as the said particle size, it becomes possible to adapt with the said slaked lime type material and sand.

The cement as the slaked lime material is mixed with the inorganic colorant and stirred for a certain time.
Cement is 10 to 75% by weight, inorganic colorant is 0.1 to 0.5% by weight, and stirring is performed for 60 to 120 minutes.
By the mixing and stirring, the inorganic colorant penetrates deeply into the cement particles, and the cement is colored.

On the other hand, the inorganic colorant is mixed into the sand and stirred for a certain time.
Sand is 10 to 75% by weight, inorganic colorant is 0.1 to 0.5% by weight, and stirring is performed for 60 to 180 minutes.
By the mixing and stirring, the inorganic colorant penetrates deeply into the sand particles and the sand is colored.

The above mixed and stirred materials are further mixed and stirred.
Therefore, the mixed state is 10 to 75% by weight of sand, 10 to 75% by weight of cement, and 0.1 to 0.5% by weight of inorganic colorant. Mix and stir for 30-120 minutes and apply the finished material to building walls, ceilings, and the like.
