Embodiment

[0123] Hereafter, although an Example demonstrates this invention more concretely, this invention is not limited to these Examples. In addition, "part" and "%" in the following example represent "part by mass" and "% by mass", respectively.

[0124] [coated board]

[0125] On the slate board (600×900×3mm), the coating amount is 100g / m 2 "EP シーラーtransparency" (manufactured by Kansai Paint Co., Ltd., water-based acrylic emulsion-based sealer) was roller-coated and dried to obtain a coated panel.

[0126] [Primer coating]

[0127] Primer paint (X-1): "Ales Aqua Gloss White" (manufactured by Kansai Paint Co., Ltd., acrylic resin-based water-based paint).

[0128] [Add paint with colored paint particles]

[0129]

manufacture example 1

[0131] 285 parts by mass of deionized water and 1 part by mass of "Newcol 707SF" (Note 1) were added to a four-necked flask with a capacity of 2 liters, and nitrogen substitution was performed, followed by maintaining at 85°C. 3% parts of the pre-emulsion (preemulsion) formed by emulsifying the components of the following composition were added thereto; 123 parts by mass of the initiator aqueous solution obtained by dissolving 3 parts by mass of ammonium persulfate in 120 parts by mass of deionized water Of these, 41 parts by mass were added dropwise to the flask over 4 hours after 20 minutes after the addition was completed.

[0132]

[0133] After completion of the dropwise addition, it was further kept at 85° C. for 2 hours, then the temperature was lowered, and the pH was adjusted with aqueous ammonia when it reached 40 to 60° C. to obtain an emulsion (a1) with a solid content of 55%. The average particle diameter of the emulsion (a1) was 175 nm, and pH was 8.3.

manufacture example 2

[0137] 285 parts by mass of deionized water and 1 part by mass of "Newcol 707SF" (Note 1) were added to a four-necked flask with a capacity of 2 liters, and nitrogen substitution was performed, followed by maintaining at 85°C. 3% of the pre-emulsion obtained by emulsifying the components of the following composition, and 123 parts by mass of an initiator aqueous solution obtained by dissolving 3 parts by mass of ammonium persulfate in 120 parts by mass of deionized water were added thereto. 41 parts by mass, and 20 minutes after the addition was completed, the remaining pre-emulsion and ammonium persulfate aqueous solution were dripped into the flask over 4 hours.

[0138]

[0139] After the dropwise addition was completed, it was further kept at 85°C for 2 hours, and then the temperature was lowered to 40˜60°C. Next, the pH was adjusted with aqueous ammonia to obtain an emulsion (a2) with a solid content of 55%. The average particle diameter of the emulsion (a2) was 180 n...

Abstract

The invention provides a stone pattern coating forming method for reproducing stone pattern with visible granite spots by painting composition. The method comprises the steps of (1) forming a first spot patterned coating on a surface to be coated and (2) forming a second spot patterned coating on the first spot patterned coating, wherein the chromatic aberration delta E between at least one spot pattern obtained in the first step and at least one spot pattern obtained in the second step equals to 15.

Description

technical field [0001] The invention relates to a method for forming a stone-like texture coating film and a coated article coated in a stone-like texture. Background technique [0002] In recent years, as the interior and exterior decoration materials of buildings, it is generally preferred to present stone-like grains with the appearance of natural stones such as granite (also known as Mikage stone). Granite is generally a rock with relatively coarse grains, and its color is, for example, black, brown, white, Wide range of colors such as russet or green. [0003] Conventionally, many paint compositions and coating methods capable of forming a coating film having a stone-like appearance have been proposed in order to create a stone-like texture by painting. [0004] For example, Patent Document 1 describes a construction method of a natural stone grain coating material as follows: a primer material containing aggregates of a specific average particle size in a synthetic re...
