|Description:||For the first time influence of the carbon nanotubes obtained by catalyst synthesis in pseudoliquid layer and activated and non-activated carbon nanotubes obtained in high-tension discharge plasma on the mechanical-and-physical and pr otective properties of coating on the base of modified alkyd and epoxy primers was investigated. Carbon nanotubes injection methods in the form of suspension in polar (acetone, cyclohexanone, butanol-1, ethyl cellosolve) and non-polar ( o-dimethylbenzene) solvents for alkyd primers and in the form of suspension in Р -5 А solvent and curing agent for epoxy primer were examined. In all cases the carbon nanotubes suspension in curing agent and solvent was produced by previous dispersion in cell ultrasonic bath during 15 minutes with further mixture during 20 minutes on laboratory dissolver with milling mixer. The investigation showed that modification of the alkyd primer Belakor with carbon nanotubes suspension in polar solvents increases primer properties to a greater degree than carbon nanotubes suspension in non-polar solvents. For epoxy primers it was determined that modification with carbon nanotubes suspension in solvents is more effective than in curing agent. The modification of epoxy primer with carbon nanotubes suspension in curing agent decreases coating properties in many cases, probably because of functional groups adsorption on the surface of carbon nanotubes, which results in under-cured coatings; it can be seen from decreasing hardness, and consequently, protection properties.|
