Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a multicolored paint that can be applied in one coat to create a multicolored pattern.

Conventionally, multi-colored paints include combinations of two or more different types of vehicles, such as a combination of an oil-based colored dispersed phase and an aqueous dispersion medium, or a combination of an aqueous colored dispersed phase and an oil-based dispersion medium. As a result, many of them are multi-colored.

However, in this case, the combination must be selected taking into account the affinity and incompatibility of the precepts to be mixed with each other, and this is subject to certain restrictions. There was some regret about the lack of freedom of choice.

In addition, many of the conventional multicolored paints were generally inferior in coating film stability, weather resistance, storage stability, and painting workability.

The object of the present invention is to provide a single-coat multicolor paint, which can be made into a variety of colors by using a single and arbitrary polymer or varnish as a vehicle, and which also has the above-mentioned film stability and weather resistance. The object of the present invention is to provide an improved multi-coating paint that has excellent properties such as painting workability and exhibits a unique design with unevenness and thickness in the coating film.

Therefore, the present invention provides a plurality of types of colored floc coarse grains having mutually different colors, which are made by kneading one or more types of powder particles containing pigments with a fibrillating polymer and organically bonding them into a floc-like shape. The subject matter is a multicolored paint characterized by being mixed with a certain amount of a predetermined vehicle.

To manufacture such a multicolored paint, first of all, the powder and granular materials that serve as the pigment and the fibrillating polymer are essential ingredients, and preferably, an increased amount of powder such as aggregate and filler is added to these to a predetermined amount. By kneading under the following conditions, the above-mentioned fibrillating polymer is fibrillated, and the powder and granules are organically bonded through the fiber network structure to form a floc-like mass, and the floc-like mass is then shaped into a desired size. The flocs are crushed to produce coarse colored flocs.

Then, the multiple types of colored floc coarse grains with different colors made in this way are mixed with a certain amount of a general vehicle commonly used as a coating film-forming material in the required mixing ratio, and the desired amount is obtained. Get multicolored paint.

Examples of pigments used in the production of colored coarse grains include titanium oxide, carbon, phthalocyanine blue, Bengara,
Iron oxide, ocher, or any other material may be used.

Further, as fillers and aggregates, any powder or granules having a particle size of about 500 μm or less, such as calcium carbonate, silica sand, clay, talc, and glass powder, are generally used.

On the other hand, fibrillating polymers become stringy and form a fine web-like fiber network by applying a predetermined external force such as shearing force, compression force, or stretching force at a predetermined temperature. It has the property of surrounding and organically bonding other substances, that is, powder and granules, and is generally preferable, for example, unfired fluorine-containing resin made by emulsion polymerization called fine powder. , olefin resins, derivatives of olefin resins, polyamide resins, and the like.

Further, more specifically, the above-mentioned fluororesin is, for example, 4
Examples include ethylene fluoride, ethylene tetrafluoride-67 fluoropylene copolymer, ethylene tetrafluoride-perfluoroalkyl vinyl ether copolymer, ethylene trifluoride chloride, and vinylidene fluoride.

This fibrillating polymer is generally kneaded in powder form with other powders such as pigments, but it can also be used as an aqueous suspension.

The kneading may be carried out using a blender, a ribbon blender, etc., and in order to fibrillate the polymer as quickly and well as possible, the temperature should be at room temperature or higher, particularly preferably at 80°C.
It is desirable to knead at a temperature of about 170°C.

The amount of the fibrillating polymer added to the pigment or other powder may be determined as appropriate within the range that allows a flocculent mass with the desired properties to be obtained after kneading, but it is generally 100 parts by weight of the powder. It is desirable to use the amount within the range of about 0.1 to 20 parts by weight.

If the amount is too small, it will be difficult to obtain good organic bonding of the powder, and if it is too large, the cost disadvantage will increase.

Generally preferred properties of floc-like lumps are that the entire powder or granule material is organically bonded, easily deforms plastically when lightly squeezed with a fingertip, and easily torn into small pieces when pulled lightly with a fingertip. It is in a state where it can be granulated.

The size of the colored floc particles produced by crushing the floc-like lumps is appropriately determined in relation to the multicolored pattern to be expressed on the painted surface.

The same applies to the mixing ratio of coarse grains of colored flocs having mutually different colors.

The size of general floc coarse particles is 1~20mrILφ
It is done to a certain extent.

When the colored floc coarse particles are mixed, the vehicle component can be one or a mixture of two or more of all the materials conventionally used as paint film-forming materials.

For example, varnish, resin emulsion or latex can be used.

The most suitable vehicle may be selected in relation to the properties expected of the coating film.

The colored flock coarse particles and the vehicle component may be kneaded by, for example, a vacuum machine, or may be carried out using paint rolls whose roll spacing is adjusted so that the colored flock coarse particles are not crushed. , or any other kneading means can be employed.

Needless to say, various additives such as an anti-sag agent, a dryer, and the like may be added as necessary during this crosstalk.

The multicolored paint of this invention is mainly applied to the interior and exterior of buildings by spray painting, troweling, etc.; In addition to being able to form an amorphous multicolored pattern, this coating film has a unique design appearance with a thick and uneven surface.

Also, since the multicolored paint of this invention can be made into multiple colors with a single vehicle component, almost any type of polymer or varnish can be used as the vehicle.
It is possible to easily produce multi-colored paints of all kinds, whether water-based or oil-based.

In addition, since the vehicle component is impregnated inside the colored block coarse particles and is completely integrated with it, the stability of the coating film is extremely excellent, and the coloring block coarse particles and vehicle component are completely integrated. Since there is no possibility that the components will be compatible with each other,
It has good shelf life and excellent storage stability.

Moreover, since the colored floc coarse particles are themselves in the form of flocs, there is little rebound from the surface to be coated even when high-pressure spray coating is applied, and the coating workability is extremely good.

Next, examples of this invention will be shown.
