Embodiment 1

[0040] Example 1: Synthesis of polyurethane foam (porous PU) with a porous skeleton.

[0041] At room temperature, 100g of propylene glycol polyether 3000 (Jurong Ningwu New Material Development Co., Ltd.), 100g of MDI (Huntsman Chemical Trading Co., Ltd.) , 1g methyl silicone oil (Sinopharm Group Chemical Reagent Co., Ltd.), 0.5g triethylenediamine (Sinopharm Group Chemical Reagent Co., Ltd.), 0.2g stannous octoate (Sinopharm Group Chemical Reagent Co., Ltd.), 6g water, 10g nano calcium carbonate (Shanghai Crystal Pure Biochemical Technology Co., Ltd.) and 10g of graphene oxide (Shanghai Crystal Pure Biochemical Technology Co., Ltd.) were mixed and stirred for 2 minutes, and the mixture in the container was left to stand for 10 minutes. After it was foamed and hardened for 2 hours, it was washed with acetone Finally, according to the weight-volume ratio of 1g:5mL, the foam was placed in 1mol / L hydrochloric acid ethanol solution for 2h, and 200g of polyurethane foam (porousPU)...

Embodiment 2

[0042] Example 2: Synthesis of polyurethane foam (porous PU) with a porous skeleton.

[0043]At room temperature, 200g of propylene glycol polyether 3000 (Jurong Ningwu New Material Development Co., Ltd.), 200g of MDI (Huntsman Chemical Trading Co., Ltd.) , 10g methyl silicone oil (Sinopharm Chemical Reagent Co., Ltd.), 2g triethylenediamine (Sinopharm Chemical Reagent Co., Ltd.), 2g stannous octoate (Sinopharm Jingchun Biochemical Technology Co., Ltd.) and 100g graphene oxide (Shanghai Jingchun Biochemical Technology Co., Ltd.) were mixed and stirred for 5 minutes, and the mixture in the container was left to stand for 10 minutes. The weight-to-volume ratio of 1g:5mL put the foam in 2mol / L hydrochloric acid ethanol solution for 2h, take it out and dry it to get 400g of polyurethane foam (porousPU) with a porous skeleton.

Embodiment 3

[0044] Embodiment three: cross-linking of graphene oxide and polyurethane foam.

[0045] Submerge 100g of the polyurethane foam (porous PU) with a porous skeleton obtained in Example 1 into 200mL of graphene oxide solution with a concentration of 4mg / mL, add 10mL of ethylenediamine, squeeze continuously to remove air bubbles, and react at 80°C 8h, after washing and drying with water, 105g of graphene oxide-polyurethane composite foam (porous PU@rGO) was obtained.

Abstract

The invention discloses a graphene oxide-polyurethane composite foam, a preparation method and application thereof. Specifically, at room temperature, polyether polyol, polyisocyanate, foam stabilizer, triethylenediamine, stannous octoate, water, nano-calcium carbonate and graphene oxide were first synthesized into A polyurethane foam with a porous skeleton, and then immersing the obtained polyurethane foam with a porous skeleton in a graphene oxide solution, adding a crosslinking agent, performing a crosslinking reaction, washing and drying to obtain a graphene oxide-polyurethane composite foam. Compared with ordinary polyurethane, the graphene oxide-polyurethane composite foam of the present invention has higher adsorption efficiency, stronger hydrophobicity and lipophilicity and mechanical properties, and has more advantages in oil storage and transportation and water surface / underwater oil pollution treatment. It causes secondary pollution to the environment, and the raw materials are easy to obtain and the preparation is convenient, so it can be used for large-scale industrial production.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a novel graphene oxide-polyurethane composite foam material, its preparation method, and its application in oil-water separation and oil storage and transportation. Background technique [0002] With the development of modern industry, people's living standards are improving day by day, and with it, the living environment has also undergone great changes. The development of industry has undoubtedly made a huge contribution to the development of the economy, but due to the lack of reasonable planning and management of some enterprises, their industrial production process has caused serious environmental pollution, especially the pollution of water resources. The daily discharge and sudden leakage accidents of crude oil, refined oil and organic chemicals have caused serious threats to people's health, life safety and the natural environment. The treatment met...
