One of the ways to reduce the duration of impregnating the reentry vehicles thermal insu-
lation blankets is the viscosity reduction of the binding substance by means of dispersing
the carbon nanotubes in it under the ultrasonic treatment. The article considers the re-
sults of investigating the behaviour of nanosuspension with the carbon nanotubes con-
centration at a level of 0,02 % from the bakelite lacquer LBS-4 mass when varying the
duration of the ultrasonic treatment and the relaxation time. According to the experi-
mental findings we have developed a mathematical model of model of the behavior of
binding substance. It is shown experimentally and analytically that ultrasonic nanomodi-
fication of the formaldehyde binding substance LBS-4 by carbon nanotubes does not ex-
ert a considerable impact on the viscosity of the substance.
Keywords:
