Environment-friendly antibacterial finger painting pigment containing nano-silver modified silicon dioxide colored composite microspheres

The invention relates to the field of pigments, and discloses an environment-friendly antibacterial finger painting pigment containing nano-silver modified silica colored composite microspheres, which comprises 3-7% of nano-silver modified silica colored composite microspheres, 9-17% of modified starch, 7-14% of edible sodium chloride, 5-10% of edible glycerol and the balance of water. Nano-silver modified silicon dioxide colored composite microspheres are added into the finger painting pigment. The nano-silver modified silicon dioxide colored composite microspheres instead of a traditional powder pigment or color agent are added into the finger painting pigment, so that the finger painting pigment is environment-friendly and non-decolorizing, and has excellent antibacterial performance. 本发明涉及颜料领域，公开了一种含纳米银修饰二氧化硅彩色复合微球的环保抗菌手指画颜料，包括：纳米银修饰彩色二氧化硅复合微球3～7%，变性淀粉9～17%，食用氯化钠7～14%，食用甘油5～10%，余量水。本发明在手指画颜料添加纳米银修饰二氧化硅彩色复合微球。本发明将纳米银修饰二氧化硅彩色复合微球代替传统粉末颜料或色素加入到手指画颜料中，不仅赋予手指画颜料环保且不脱色的功能，而且还使其具有优异的抗菌性能。
