発泡プラスチック断熱材の燃焼性状に関する基礎的研究: コーンカロリーメータ試験による燃焼性状と材料組成に関する考察

摘要

JIS A 9511に示されている5種類の断熱材について、コーンカロrnリーメータ試験による燃焼性状に関する検討を行った。rn（1）燃焼性状に関する知見rn①市販品である発泡プラスチック断熱材を対象とした試験結果からrnの知見rn1. 同種断熱材では、概ね単位質量あたりの発熱量は一定であったが、rn燃焼する過程で性状が異なる場合があり、その原因としては、断熱rn材の材料組成が関与している。%This paper is intended to study on combustibility of the cellular plastics insulation material, and the following points were examined.rn1. Obtaining a quantitative knowledge on combustibility of various cellular plastics insulation material by cone calorimeter method.rn2. Clarifying necessary information on the cellular plastics insulation material for the cause pursuit when there is a difference like combustibility.rnIn conclusion, the following knowledge is obtained for this study.rn1. In the same cellular plastics insulation, the total heat release for each unit mass was roughly constant. However combustibility might be different because of the process of burning, and it is thought that the material composition of the cellular plastics insulation takes part as the cause.rn2. In cellular plastics insulation except rigid urethane foam, the grasp of combustibility is roughly possible by considering informationrnon the material composition from MSDS and information on thermal behavior from document.rn3. In rigid urethane foam, to understand combustibility in detail, it is necessary to clarify the factor that contributes to combustibility.rnResult of examination, the nurate index and the kind of the foaming agent contribute as the factor.
