AI Technical Summary
Existing silver-loaded inorganic antibacterial agents have insufficient dispersibility in ABS resin matrix, limited antibacterial long-term effect, are prone to discoloration, and have insufficient compatibility with cosmetic media. This results in unstable antibacterial performance of mascara bottle bases, which cannot meet high hygiene standards and appearance requirements.
Mesoporous silica is used as a carrier for silver active materials. Through modification with silane coupling agents, combined with organic antibacterial additives and color change inhibitors, the composition ratio and processing technology are optimized to achieve uniform dispersion and long-term sustained release of antibacterial agents in ABS resin, inhibit color change, and ensure the antibacterial performance and appearance stability of the material.
It achieves an antibacterial rate of over 99.2% and a long-lasting effect retention rate of 97% with low antibacterial agent addition. The material has excellent appearance quality, good mechanical properties and processing performance, and meets the high standards required for cosmetic packaging.
