钢琴黑PMMA材料的影响因素研究
Study on key factors influencing the piano-black-colored PMMA material
摘要
Abstract
This study investigates the effects of toner type,toughening agents,and lubricants on the mechanical properties and surface aesthetics,specifically gloss and blackness,of polymethyl methacrylate(PMMA).The influence mecha-nism of toughening agents on blackness is also analyzed.The results indicate that PMMA formulated with a self-devel-oped organic black pigment exhibits superior blackness and gloss compared to carbon black-based formulations,achieving a more pronounced piano black effect.Among the tested toughening agents,the transparent agent(M-270)significantly enhances the material's toughness while preserving its high-gloss,deep-black appearance.At a PMMA/M-270 mass ra-tio of 90/10,the impact toughness increases by nearly 40%relative to neat PMMA.Lubricants were found to moderate-ly affect mechanical performance,with ethylene bis-stearamide demonstrating the best overall balance of properties.关键词
