摘要
研究了防火涂料基料树脂聚丙烯酸酯玻璃化转变温度、相对分子质量、乳胶粒径与炭化层结构以及防火性能之间的联系。研究结果表明,基质树脂玻璃化转变温度越低,乳胶粒子的平均粒径越小,防火涂料的耐火性能就越好;选用相对分子质量6.8万左右的基料树脂能得到泡孔分布均匀、整体强度较好的炭化层结构,并且防火涂料耐火性能也较好。
The relationships between the glass transition temperature, molecular weight and particle diameter of the resin binder of polyacrylate latex, structures of the carbonized layers and the fire - retardant properties were studied. Results showed that with the decrease of the glass transition temperature and the size of the latex particles of the resin binder, the fire - retardant properties were improved. Additionally, when the molecular weight was about 68 000, a carbonized layer with well - distributed inner bubbles and high overall strength was formed, and the fire- retardant properties were also good.
