建筑绝热用石墨改性挤塑聚苯乙烯泡沫板的应用及标准解读

挤塑聚苯乙烯泡沫塑料板是一种绝热性能优异、性价比较高的保温材料，其多项性能指标优于其他建筑保温材料。随着我国建筑防火要求的提高，新型保温材料的涌现，市场竞争愈发激烈，挤塑聚苯乙烯泡沫塑料板的市场份额被侵占压缩。为了保有市场份额，应对新材料的冲击与建筑防火要求的提高，研究机构和企业研制出石墨改性挤塑聚苯乙烯泡沫塑料板。本文基于JC/T 2627—2021《建筑绝热用石墨改性挤塑聚苯乙烯泡沫板（GXPS）》标准制定过程，介绍了石墨改性挤塑聚苯乙烯泡沫塑料板的主要性能指标及应用方向，同时指出了该产品当前仍面临的问题，希望为后续研究及相关标准的制定提供参考。

Application and Standard Interpretation of Graphite?modified Extruded Polystyrene Foam Boards for Thermal Insulation of Building

Rigid extruded polystyrene foam boards are superior to other building insulation materials in many properties. They have excellent thermal insulation performance and a high ratio of performance to price. With an improvement in the fire protection standard for buildings， there a lot of new materials developed and emerged， resulting in a heavy competition of market. The market share of rigid extruded polystyrene foam boards has been occupied and reduced greatly. In order to maintain a market share and cope with the impact of new materials and the improvement of fire protection standard， graphite?modified extruded polystyrene foam boards have been developed by various research institutions and enterprises. Based on the development of JC/T 2627? 2021 “Graphite modified extruded polystyrene （GXPS） foam board for thermal insulation of building”， this paper introduced the main requirements for performance and application directions of GXPS boards and pointed out the product problems. This paper is expected to provide references for the subsequent research as well as the development of relevant standards.
