preparation example Construction

[0028] A kind of preparation method of graphene concentrated poly glue, comprises the following steps:

[0029] ① Measure graphene, dual-soluble surfactant, and non-ionic surfactant according to the volume ratio, and sequentially add volatile ethanol, propanol, etc., which are more than 1 times the total volume of the first three and whose boiling point is lower than 100 °C, in a closed container. Environmentally friendly dispersant, stir and mix evenly to make graphene dispersion;

[0030] ② Put the graphene dispersion liquid formed in ① into a pressure-resistant and temperature-resistant non-metallic container, and heat it with microwave. Due to the strong ability of graphene nanosheets to conduct electricity, conduct heat and absorb microwaves, it preferentially heats up and magnetizes rapidly, and the volatile dispersant with low boiling point on its surface and surrounding gasification forms bubbles, and the dual-soluble surfactant with high boiling point is in each graph...

Embodiment 1

[0032] The preparation of embodiment 1 graphene concentrated poly glue

[0033] ① Measure 200 ml of graphene, 300 ml of polyethylene glycol dual-soluble surfactant, 500 ml of fluorocarbon nonionic surfactant and 1000 ml of anhydrous ethanol volatile dispersant. Add anhydrous ethanol, graphene, fluorocarbon and polyethylene glycol in order to the airtight container, and stir evenly to form a neutral graphene dispersion;

[0034] ②Add the neutral graphene dispersion formed in ① into a temperature-resistant and pressure-resistant non-metallic airtight container, heat it with microwaves and keep the temperature at 90-100°C until the volatile diluent is completely evaporated and gasified to form a highly dispersed graphene Nano foam poly glue. In this step, the surface of the graphene is heated up, the volatile diluent on the surface is gradually evaporated and gasified, and the dual-soluble dispersant and the non-ionic surfactant on the surface are gradually concentrated to form ...

Embodiment 2

[0037] Embodiment 2 Graphene poly glue nanofoam

[0038]The graphene condensed poly glue prepared according to the method of embodiment 1 is added the water dilution of 1000-10000 times (volume multiple), and then the inert gases such as diluent and nitrogen, carbon dioxide are injected into the foam generator and mixed to form a highly dispersed, High-activity, high-wetting, high-conductivity, and high-stability nano-graphene polyfoam. The nano-graphene polyplastic foam is used for foam drilling, foam cementing, foam acidification, foam acid fracturing, foam fracturing, foam oil flooding, foam gas extraction, foam drainage, foam cleaning, foam fire extinguishing, etc. in oil and gas fields.

Abstract

The invention discloses a graphene concentrated polymer glue. The graphene concentrated polymer glue is composed of a graphene nano-sheet inner core, a dual-soluble surface active coating, a non-ionic surface active colloid, and the like. The volume ratio of the graphene nanosheet core is 10-30%, the volume ratio of the dual-soluble surface active coating film is 20-50%, and the volume ratio of the nonionic surface active colloid is 20-70%. The graphene concentrate has unique properties such as high dispersion, high activity, high wetting, high conductivity, high penetration, high adsorption, high foam, high specific surface, high corrosion resistance, high wear resistance, and is safe and environmentally friendly. It can be diluted with high times of oil, water, gas, acid, lye, emulsion, paint, cement slurry, resin, etc.
