Abstract

The polymeric composites material considered as one of the most isolated materials, but they have a good mechanical flexibility. The main idea of modifying these materials to be one of the applicable materials in environmental aspects. Reducing the temperature inside buildings by coating them with the modified materials will give very good results in decreasing the electrical power used. In this study, polymeric composites material were prepared a by hand- layup technique from epoxy resin (EP) as a matrix and Copper (Cu) powder with average diameter (240.91 nm) as fillers with different weight percentage (5%, 15%,25%, 35%, and 45%) to resin. Glass transition temperature and Hardness testing were investigated. The results show the maximum Glass transition temperature (Tg) of (EP/Cu) composites were the value (58.949°C) at (65%EP + 35%Cu). Increase hardness with Copper concentration increase, and it has maximum values of (83.9) for (55%EP + 45%Cu). This composite can be used in the coating surfaces and floors to match the temperature of our country warm in summer.

铜添加剂对环氧树脂玻璃化转变温度和硬度的影响

高分子复合材料被认为是最孤立的材料之一，但它们具有良好的机械柔韧性。主要思想是对这些材料进行改性，使其成为环境方面的应用材料之一。通过涂覆改性材料来降低建筑物内部的温度，将在减少电力使用方面取得非常好的效果。本研究以环氧树脂(EP)为基体，以平均直径(240.91 nm)的铜粉(Cu)为填料，分别以树脂的重量百分比(5%、15%、25%、35%和45%)为填料，采用手工铺层法制备了高分子复合材料。研究了玻璃化转变温度和硬度测试。结果表明:(EP/Cu)复合材料在(65%EP + 35%Cu)时的最高玻璃化转变温度(Tg)为58.949℃;硬度随铜浓度的增加而增加，(55%EP + 45%Cu)硬度最大值为(83.9)。该复合材料可用于涂层表面和地板，以配合我国夏季温暖的温度。
