Carbon microsphere/magnesium borate whisker hybrid reinforced carbon foam material and preparation method thereof
The invention discloses a carbon microsphere/magnesium borate whisker hybrid reinforced carbon foam material which comprises the following components in percentage by mass: 20%-23% of phenolic microspheres, 70%-77% of a carbon nanotube modified resin matrix and 5%-10% of magnesium borate whiskers. The invention also discloses a preparation method of the carbon foam material. The preparation method specifically comprises the following steps: preparing a carbon nanotube suspension; preparing a hydroxymethyl phenol solution; preparing a carbon nanotube modified resin matrix; carrying out coupling reaction on the magnesium borate crystal whiskers to obtain coupled magnesium borate crystal whiskers; and carrying out ultrasonic stirring, injection molding and curing on the phenolic microspheres, the carbon nanotube modified resin matrix and the magnesium borate whiskers, and carrying out carbonization treatment on the obtained phenolic foam composite material to obtain the carbon microsphere/magnesium borate whisker hybrid reinforced carbon foam material. The carbon foam material prepared by the method disclosed by the invention is light in weight, excellent in mechanical property and excellent in electromagnetic shielding performance in an X wave band, and meets the requirements of industrial and commercial electronic products.
