Embodiment 1

[0049] A graphene composite material for a fuel-saving ambulance, comprising: 5% graphene material, 85% mineral powder, 5% additive, and 5% binder. Wherein graphene or graphene oxide powder is prepared by mechanical exfoliation; mineral powder contains iron, zinc, copper, cobalt; additive contains polyisobutylene amine, n-butanol; binder contains polyvinyl alcohol, the above bonding The agent contained 0.03% polydimethylsiloxane and 0.07% cobalt acetylacetonate hydrate.

[0050] A kind of preparation method of the graphene composite material that is used for fuel-saving ambulance, its concrete steps are as follows:

[0051] (1) Weigh the negative ion powder raw material, mix it with graphene or graphene oxide evenly, grind it through a grinder for 5 minutes to form a fine sand powder, separate the heavy metal through magnetic separation, and sieve to obtain the graphene material. The above negative ion The body includes the following raw materials in parts by weight: 20 parts...

Embodiment 2

[0057] A graphene composite material for a fuel-saving ambulance, comprising: 5% graphene material, 85% mineral powder, 5% additive, and 5% binder. Wherein graphene or graphene oxide powder is prepared by mechanical exfoliation; mineral powder contains iron, zinc, copper, cobalt; additive contains polyisobutylene amine, n-butanol; binder contains polyvinyl alcohol, the above bonding The agent included 0.05% polydimethylsiloxane and 0.05% cobalt acetylacetonate hydrate.

[0058] The preparation method of the graphene composite material in this embodiment is consistent with the steps in Example 1, and a block-shaped graphene composite material is obtained.

Embodiment 3

[0060] The raw material of graphene composite material in this embodiment is consistent with embodiment 2.

[0061] The preparation method of graphene composite material in the present embodiment is consistent with other steps in embodiment 2, difference only is: in step (1), add grinding aid, its addition is 0.03% of negative ion powder weight, this grinding aid It includes propylene oxide and 2-mercaptobenzimidazole, and its weight ratio is 2.3:0.7. When the two are added to the grinding process, the mechanical energy is used to combine with the surface layer of the graphene structure, which can not only improve the infrared radiation rate of graphene, but also link Part of the negative ions stay on the surface of graphene, which weakens the link between negative ions and graphene, and the negative ions are released more easily, which shortens the time required for the release of negative ions after the block structure contacts gasoline to improve oil quality, and achieves fu...

Abstract

The invention provides a graphene composite material used for fuel-saving ambulances, which belongs to the technical field of energy saving, and includes a matrix and a graphene material dispersed in the matrix, the matrix is ​​mineral powder, and the graphene material is loaded with negative ions; the graphene The composite material is a massive porous structure with a pore size less than 10 microns. The preparation method comprises mixing at least one binder with at least one additive, graphene powder, and mineral powder, and then performing compression molding to immobilize and disperse the graphene material in the mineral powder matrix. The graphene composite material in the present invention can provide negative ions to improve fuel combustion efficiency and power output, reduce fuel consumption per 100 kilometers after use, reduce carbon deposits in auto parts, reduce waste gas emissions, and lighten tail gas odor; the preparation method can avoid graphene Agglomeration maintains high infrared radiation rate, increases product anion release, shortens release reaction time, reduces product surface roughness and friction coefficient, enhances product wear resistance, and has low production cost.

Description

technical field [0001] The invention belongs to the technical field of energy saving, and in particular relates to a graphene composite material used for fuel-saving ambulance vehicles and a preparation method thereof. Background technique [0002] As my country's motor vehicle emission regulations become increasingly stringent, the cleanliness of vehicle fuels has an increasingly prominent impact on vehicle emissions. Affected by the refining process, the content of olefins and aromatics in gasoline in my country is relatively high, which is easy to generate carbon deposits in the engine's fuel nozzles, intake valves, and combustion chambers, resulting in insufficient combustion of gasoline for vehicles and increased exhaust emissions. energy, and the exhaust gas has caused environmental pollution. [0003] The internal combustion of automobile engines will emit harmful gases, mainly CO, HC compounds, nitrogen oxides (nitrogen monoxide and nitrogen dioxide), and people have...
