Abstract

The invention discloses a functionalized graphene modified polypropylene wood-plastic plate and a preparation method thereof. The functionalized graphene modified polypropylene wood-plastic plate comprises the six steps: preparing ethanediamine modified graphene oxide, preparing cyanuric chloride grafted graphene oxide, preparing pentaerythritol borate, preparing borate-triazine grafted graphene oxide, preparing functionalized graphene and preparing the functionalized graphene modified polypropylene wood-plastic plate. The grafted borate, triazine and cyclodextrin functional groups can achieve a synergistic effect during flame retardance, under the synergistic effect of the three functional groups, the effects of heat insulation, oxygen resistance and smoke suppression can be achieved, and the flame retardance of the polypropylene wood-plastic plate is remarkably enhanced; in addition, borate, triazine and cyclodextrin groups grafted on the surface of the graphene oxide can effectively improve the compatibility of the graphene oxide and polypropylene, the problem that graphene is prone to agglomeration in the polypropylene wood-plastic plate is solved, and escape of polypropylene thermal degradation products can be slowed down due to the high specific surface area of the graphene; and the thermal stability of the polypropylene material is improved.

Description

technical field [0001] The invention relates to the technical field of flame-retardant wood-plastic panels, in particular to a functionalized graphene-modified polypropylene wood-plastic panel and a preparation method thereof. Background technique [0002] In recent years, wood-plastic panels have been widely used in decorative panels due to their good environmental protection, plasticity, and processability, showing the advantages of simple installation and convenient construction. Specific application fields include polypropylene wood-plastic panels, polyethylene wood-plastic panels As its application becomes more and more extensive, the requirements for wood-plastic materials in industrial production and practical applications are also getting higher and higher. However, traditional wood-plastic materials have poor mechanical strength and low flame-retardant efficiency in production and practical applications. and other shortcomings. [0003] The traditional method to so...
