Embodiment
[0073] Hereinafter, although an Example is given and this invention is demonstrated in more detail, this invention is not limited to these Examples.
[0074] 〔Manufacture of resin composition (masterbatch)〕
[0075] The resin compositions of Examples 1 to 3 and Comparative Examples 1 to 2 were manufactured by the following methods.
[0076]
[0077] Aluminum paste (trade name (model): "5422NS", manufactured by Toyo Aluminum Co., Ltd., 500 g of solid content) was dispersed in 2 L of mineral spirits to obtain a dispersion liquid. This dispersion liquid was filtered and washed to obtain aluminum flake particles. Next, the aluminum flake particles, 3 g of deionized water, and 3 g of γ-aminopropyltriethoxysilane (trade name (model) "KBE-903", manufactured by Shin-Etsu Chemical Co., Ltd.) were dissolved in 60 g of isopropanol to obtain a treatment solution, which was put into a commercially available kneader mixer. Furthermore, these were kneaded in the said kneader mixer for ...
Embodiment 2
[0080] The deionized water contained in the above-mentioned treatment solution was set to 1 g, and γ-aminopropyltriethoxysilane was set to 1 g, except that, the same method for producing a resin composition as in Example 1 was implemented, whereby A resin composition (masterbatch) is produced.
Embodiment 3
[0082] The deionized water contained in the above-mentioned treatment solution was set to 25 g, and γ-aminopropyltriethoxysilane was set to 25 g, except that, the same method for producing the resin composition as in Example 1 was implemented, whereby A resin composition (masterbatch) is produced.
[0083]
[0084] The aluminum flake particles contained in the dispersion obtained by dispersing the above-mentioned aluminum paste (trade name (model number): "5422NS", manufactured by Toyo Aluminum Co., Ltd., 500 g of solid content) in mineral spirits without using the above-mentioned coupling Instead of kneading the treatment solution of the agent, an aluminum flake particle dispersion having a solid content of 55% by mass was prepared from the dispersion. Next, the above-mentioned aluminum flake particle dispersion (solid content 400g) was mixed with the same ABS resin as in Example 1 to obtain a mixture, and the same extruder as in Example 1 was used to obtain the same extrud...
