Preparation process of graphene PU foam thermal insulation integrated board
By using fractional online mixing and high-shear dispersion technology, graphene is divided into A and B components and mixed online with polyurethane foam. This solves the dispersion and chemical compatibility problems of graphene-modified polyurethane foam, achieving performance improvement and stable production, especially improvements in compressive strength and thermal conductivity.

Abstract
本发明属于轻质建筑材料领域，具体涉及一种石墨烯PU泡沫保温一体板的制备工艺，包括浆料制备工段、网笼与聚乙烯板组装工段、浇注工段、蒸压养护工段、聚氨酯灌装工段以及成品打包工段，其中在聚氨酯灌装工段中，将石墨烯原料分为A料和B料，将黑料供给管路和白料供给管路都分为主流路和支流路，A料与部分黑料、B料与部分白料在支流路内在线预混成母料，再连同主料经高压混合灌装至混凝土胚体内，制得保温一体板，这种部分主料在线预混的方式，有效降低了混合的副反应风险，同时不影响主体黑料与白料的原始状态，而且A料锚固于硬段，B料分散于软段，形成跨相纳米网络，有效提高了保温一体板的力学、保温等性能。
