摘要:
利用有机硅憎水剂对珍珠岩进行憎水改性处理,并将改性后的珍珠岩分别与聚乙烯醇(PVA)、脲醛树脂(UF)以及三聚氰胺脲醛树脂(MUF)进行填充复配制得三种复合材料,采用标准试验方法测定了三种憎水改性复合材料的密度、燃烧性能、烟密度、氧指数、导热系数等相关特性参数,考察了不同配比下的材料的导热性能和燃烧性能。结果表明,改性处理后珍珠岩复合材料的阻燃性能均有效增强,且表现出一定的协同效应。采用PVA的复合材料密度最低,为185.8kg/m3;导热系数最低,为0.046w/m·k;烟密度仅10%;受热分解慢。而采用UF和MUF时其复合材料均表现出良好的阻燃特性,MUF复合材料氧指数达到了52.5%。
Abstract:
Firstly, the hydrophobic medication of perlite was carried out by organosilicon hydrophobic agent. Secondly, three composites were prepared by filling the composition of the hydrophobically modified pearlite with polyvinyl alcohol (PVA), urea-formaldehyde resin (UF), and melamine urea formaldehyde resin (MUF) respectively. Thirdly, properties of the three hydrophobically modified composites materials, including density, combustion performance, smoke density, oxygen index, and thermal conductivity, were determined by standard test methods, and the thermal conductivity and combustion properties of materials with different ratios were also investigated. The results indicated that the flame retardancy of a the modified pearlite composite materials was improved, showing some synergistic effect. The composite material with PVA is lowest density and thermal conductivity, being 185.8kg/m3 and 0.046w/m·k respectively, with a smoke density of only 10% and a slow heating decomposition. While composite materials with UF and MUF showed good flame retardancy, with the latter claiming an oxygen index of 52.5%.
