Abstract

The present invention relates to graphene-containing composite polyurethane foam, and the polyurethane foam contains graphene; the graphene is introduced in the form of a carbon nanostructure composite; and the carbon nanostructure composite comprises the graphene and SP3 hybrid structure carbon. Through use of the specific carbon nanostructure composite, the purpose of achievement of compounding of polyurethane only by simple mixing of the carbon nanostructure composite and a polyether polyol and then polymerization with a polyisocyanate, the step of compounding of the carbon nanostructure composite is omitted, the process is simple, and the foam is in seamless connection with equipment in the prior art.

Description

technical field [0001] The invention belongs to the field of polymer materials, and specifically relates to a composite polyurethane foam containing graphene, a preparation method and an application. The composite polyurethane foam containing graphene has a far-infrared function and can be used to make pillows, mattresses, cushions, Cushions, sofas, waist protectors, insoles, bras, car seats, toilet seat cushions or hand warmers emit far infrared rays to play a health care function. Background technique [0002] The full name of polyurethane is polyurethane, which is a general term for macromolecular compounds containing repeated carbamate groups in the main chain. It is formed by addition polymerization of organic diisocyanate or polyisocyanate and dihydroxy or polyhydroxy compounds. [0003] CN104892886A discloses a rigid urethane foam with low smoke emission and its preparation method and application. The polyurethane foam is prepared from a composition comprising polyis...
