Embodiment 1

[0037] (1) Dried the fresh bamboo and pulverized it with a pulverizer, and sieved to obtain bamboo powder with a mesh size of less than 100. The obtained bamboo powder was placed in a high-temperature tube furnace, and calcined at 550° C. for 1 hour to obtain bamboo charcoal powder. Take 0.3 g of bamboo powder and add it into a glass vessel, then place it in a polytetrafluoroethylene-lined stainless steel reaction kettle filled with 3 mL of concentrated nitric acid, and then move it into an oven at 120 °C for 3 h. After taking out, the acid is washed away with distilled water to obtain modified bamboo charcoal powder;

[0038] (2) Add 20 g aluminum nitrate (Al(NO 3 ) 3 •9H 2 O) Dissolve in 200 ml of deionized water, gradually add ammonia water (c=1 mol / L) dropwise to the solution while stirring at room temperature, stop the dropwise addition when pH=8, filter with suction, and obtain a precipitate. The precipitate was redissolved in 200 mL of deionized water, peptized by a...

Embodiment 2

[0045] (1) Dried the fresh bamboo and pulverized it with a pulverizer, and sieved to obtain bamboo powder with a mesh size of less than 100. The obtained bamboo powder was placed in a high-temperature tube furnace and calcined at 650 °C for 3 h to obtain bamboo charcoal powder. Take 0.3 g of bamboo powder and add it to a glass vessel, then place it in a polytetrafluoroethylene-lined stainless steel reaction kettle filled with 3 mL of concentrated nitric acid, and then move it into an oven at 120 °C for 5 h. After taking out, the acid is washed away with distilled water to obtain modified bamboo charcoal powder;

[0046] (2) 20 g aluminum nitrate (Al(NO 3 ) 3 •9H 2 O) Dissolve in 200 ml of deionized water, gradually add ammonia water (c=1 mol / L) dropwise to the solution while stirring at room temperature, stop the dropwise addition when pH=8, filter with suction, and obtain a precipitate. The precipitate was redissolved in 200 mL of deionized water, peptized by adding 0.41 ...

Embodiment 3

[0053] (1) Dried the fresh bamboo and pulverized it with a pulverizer, and sieved to obtain bamboo powder with a mesh size of less than 100. The obtained bamboo powder was placed in a high-temperature tube furnace and calcined at 850 °C for 4 h to obtain bamboo charcoal powder. Take 0.3 g of bamboo powder and add it to a glass vessel, then place it in a polytetrafluoroethylene-lined stainless steel reaction kettle filled with 3 mL of concentrated nitric acid, and then move it into an oven at 120 °C for 7 h. After taking out, the acid is washed away with distilled water to obtain modified bamboo charcoal powder;

[0054] (2) Add 20 g aluminum nitrate (Al(NO 3 ) 3 •9H 2 O) Dissolve in 200 ml of deionized water, gradually add ammonia water (c=1 mol / L) dropwise to the solution while stirring at room temperature, stop the dropwise addition when pH=8, filter with suction, and obtain a precipitate. The precipitate was redissolved in 200 mL of deionized water, peptized by adding 0...

Abstract

The invention belongs to the technical field of polymer composite material synthesis, relates to the preparation of a carbon fiber-polyurethane porous foamed material, and especially relates to a preparation method and applications of a Mg / Al / C fiber-polyurethane foamed material. The preparation method comprises the following steps: preparing a Mg / Al / C fiber material, subjecting the Mg / Al / C fiber material to hydrophobic modification, mixing hydrophobic Mg / Al / C fibers, polyether polyol NJ-330, a foaming agent, a foam stabilizer, and a catalyst at a room temperature under stirring, adding toluene diisocyanate, and carrying out one-step foaming method to obtain the foamed material. Vinyl triethoxysilane is used to carry out hydrophobic modification on the Mg / Al / C fiber material; the Mg / Al / C fiber powder is uniformly dispersed into a foamed material, the oil absorbing performance, anti-aging property, and thermal stability of the foamed material are enhanced, and the comprehensive performance of the foamed composite material is improved. Trichloromethane is taken as the adsorption object, and the test results show that the foamed material has a good oil absorbing and eliminating effect, so the foamed material can be used to process petroleum leakage, organic solvent pollution, and the like, the operation is simple, and the adsorption rate is high.

Description

technical field [0001] The invention belongs to the technical field of polymer composite material synthesis, and relates to the preparation of carbon fiber-polyurethane porous foaming material, in particular to a preparation method and application of a Mg / Al / C fiber-polyurethane foaming material. Background technique [0002] With the continuous development of the world's industry, oil field leakage, oil tanker oil leakage, oil pipeline rupture, large chemical factories, chemical raw material warehouses and other chemical raw material centralized storage accidents have caused serious pollution of rivers and oceans and brought immeasurable damage. ecological disasters and economic losses. The entry of oil and solvents into the water body will not only reduce dissolved oxygen, lead to deterioration of water quality, death of aquatic organisms and marine feeding birds, but also threaten the development of offshore fisheries, aquaculture, tourism, etc. Therefore, it is imperati...
