Abstract

Abstract:

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.

Key words: graphite modification, rigid extruded polystyrene foam board, performance introduction, standard research
