preparation example Construction

[0104] The invention provides the preparation method of the polyurethane foam containing graphene structure, comprises the steps:

[0105] A substance containing a graphene structure and non-carbon, non-oxygen, and non-hydrogen elements is introduced into the polyether polyol to prepare a polyurethane foam containing a carbon nanostructure.

[0106] The graphene structure of the present invention is preferably introduced in the form of a mixture, which preferably includes non-graphene structure components, such as amorphous carbon components.

[0107] The present invention provides a product, containing the polyurethane foam described in any one of the above technical solutions, or the polyurethane foam prepared by the preparation method described in any one of the above technical solutions; the product preferably includes pillows, mattresses, cushions, Cushions, sofas, waist supports, insoles, bras, car seats, toilet seats or hand warmers.

[0108] The polyurethane foam prov...

Embodiment 1

[0115] A compound containing carbon nanostructure obtained by the following method:

[0116] (1) Mix corn cob cellulose and ferrous chloride at a mass ratio of 1:1, stir at 150°C for 4 hours, and dry until the moisture content of the precursor is 10wt%, to obtain the precursor;

[0117] (2) In a protective atmosphere, raise the temperature of the precursor to 170°C at a rate of 3°C / min, hold for 2 hours, then program the temperature to 400°C, hold for 3 hours, then raise the temperature to 1200°C, hold for 3 hours to obtain the crude product; the procedure The heating rate is 15°C / min;

[0118](3) At 55-65°C, the crude product was pickled with 10% sodium hydroxide solution and 4wt% hydrochloric acid, and then washed with water to obtain a composite containing carbon nanostructures.

[0119] The composite of the carbon nanostructure prepared in Example 1 was subjected to Raman spectrum detection, and the results showed that the peak height ratio of the G peak and the D peak wa...

Embodiment 2

[0122] The corn cob cellulose in Example 1 is replaced by reed cellulose.

[0123] The composite of carbon nanostructures prepared in Example 2 was detected by Raman spectroscopy, and the results showed that the G peak and D peak height ratios were 4.8;

[0124] The first non-carbon, non-oxygen, and non-hydrogen element content determination method is used to detect that the composite containing carbon nanostructures mainly contains Si, Ca, Al, Fe, Mg, and S elements.

Abstract

The invention relates to composite polyurethane foam containing graphene. The polyurethane foam contains a graphene structure and non-carbon non-oxygen non-hydrogen elements. According to the invention, a specific carbon nanostructured compound is selected and used, so compounding of p-polyurethane is realized through simple mixing of the specific carbon nanostructured compound with polyether polyol and polymerization of the obtained mixture with polyisocyanate; so the step of compounding of the carbon nanostructured compound is omitted, process is simple, and seamless linkage with conventional equipment is realized.

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...
