Abstract

The invention relates to a preparation method and application of a flame-retardant coated fabric based on graphene oxide. The preparation method comprises the following steps: firstly immersing a cotton fabric in a graphene oxide aqueous dispersion to obtain a graphene oxide-coated cotton fabric, then immersing the graphene oxide-coated cotton fabric in a DMAEMA solution, carrying out ultravioletillumination to obtain a graphene oxide/PDMAEMA-coated cotton fabric, and finally, immersing the graphene oxide/PDMAEMA coated cotton fabric into ultrasonically treated hexagonal boron nitride nanosheet dispersion liquid to prepare the graphene oxide/PDMAEMA/hexagonal boron nitride sandwich-shaped layered nano-coating flame-retardant cotton fabric. The graphene oxide/PDMAEMA/hexagonal boron nitride sandwich-shaped layered nano-coating flame-retardant cotton fabric can be used for preparing a large-area fire early-warning sensor. The large-area fire early-warning sensor prepared from the flame-retardant coated fabric based on graphene oxide can realize large-area sensing, and is short in alarm time.

Description

technical field [0001] The invention belongs to the technical field of fire early warning sensors, and relates to a preparation method and application of a graphene oxide-based flame-retardant coating fabric, in particular to a graphene oxide / PDMAEMA / hexagonal boron nitride sandwich layered nano-coating resistance Preparation method of burning cotton fabric and its application in fire early warning sensor. Background technique [0002] With the continuous development of the country, the society's demand for lightweight materials is increasing, especially in the fields of construction, decoration, transportation, furniture, cables and electrical equipment. However, many common lightweight materials are highly combustible, such as polymer foams, wood, textiles, etc., and when the ignition temperature exceeds 300-500 °C, they will burn violently and the flame will spread rapidly. This easily leads to a considerable number of fire accidents every year. Fire accidents not only ...
