Abstract

Abstract In this work, the results of investigations of polyurethane materials were presented. Innovative materials based on polyurethane-polyisocyanurate (PUR/PIR) foam were obtained. Different types of additives (flame retardants, aerogels – additives that decrease thermal conductivity) are used in the composition of PUR/PIR foam. Foams are a type of composite composed of two phases: continuous (polyurethane polymers) and dispersed (composed of gases). All samples have been tested for thermal parameters: thermal conductivity, specific heat, and thermal diffusivity. Then they have been compared with each other and with a reference sample (RS) without additives. Based on the research, it was shown that innovative insulation materials were characterized by thermal conductivity λ in the range of 0.0254–0.0294 W/(m · K). The thermal properties of foams depending on the type and chemical composition of the material. Depending on the used substrates, their molar ratio, type, synthesis conditions, modifying agents and catalysts, a different polyurethane material is obtained.

聚氨酯-聚异氰脲酸酯(PUR/PIR)新型保温板热性能实验研究

本文介绍了聚氨酯材料的研究结果。以聚氨酯-聚异氰脲酸酯(PUR/PIR)泡沫为基础研制了新型材料。不同类型的添加剂(阻燃剂，气凝胶—降低导热性的添加剂)用于PUR/PIR泡沫的组成。泡沫是一种由两种相组成的复合材料:连续相(聚氨酯聚合物)和分散相(气体组成)。所有样品都进行了热参数测试:导热系数，比热和热扩散系数。并与不添加添加剂的标准样品(RS)进行对比。研究结果表明，新型保温材料的导热系数λ在0.0254 ~ 0.0294 W/(m·K)范围内，泡沫材料的热性能取决于材料的类型和化学成分。根据所用底物、它们的摩尔比、类型、合成条件、改性剂和催化剂的不同，可以得到不同的聚氨酯材料。
