Problems solved by technology

[0003] At this stage, rigid polyurethane foam is most commonly used as external wall insulation materials. How to improve its thermal insulation performance has always been a question that people think about; using phase change energy storage that absorbs or releases phase change latent heat during the phase change process Technology has also gradually entered people's field of vision. The so-called phase change energy storage material is a material that can maintain its own temperature within a specific temperature range and store or release heat by changing its physical state; Adding phase-change energy storage materials to rigid polyurethane foam can reduce the thermal conductivity of the material and improve the thermal insulation effect of the material, but the addition of phase-change energy storage materials greatly increases the fire risk of rigid polyurethane materials. Therefore, it is urgent There is a need for a new type of polymer material with improved flame retardant performance without reducing the thermal insulation performance of the material itself or even improving it.
