▎ 摘  要

NOVELTY - A composition of crystallographic modifier of metals comprises pentene; 35-40% 2,4,4-trimethyl sulfonate; 1.5-2% acrylate copolymer; 5-10% zinc dialkyl phythiophosphate; 5-10% calcium sulfonate; 1-1.5% 2.6-di-tert.-butyl-4-methyl-phenol; 20-25% hydrogenated decene homopolymer; 5-10% saturated aliphatic hydrocarbons, such as trimethylolpropane trioleate; and metal nanoparticles, preferably 1-1.5% silver nanoparticles. USE - A composition of crystallographic modifier of metals for lubrication of four-stroke, two-stroke engines, combustion and compression engines, gearboxes and reduction motors, bearings, cold chamber and air conditioning systems, and in all equipment where movement is found and consequent friction between surfaces. metal of all types and alloys. ADVANTAGE - The composition results in a product which with its synergistically combined actives uses the common lubricant as a medium, which when catalyzed by the temperature generated by the friction migrates to the surface of the metals, creating an extremely strong protective barrier. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of composition of crystallographic modifier of metals which involves charging reactor with 30% hydrogenated decene hompolymer formulation under agitation of greater than or equal to 110 rpm, adding all 2,6-di-tert.-butyl-4-methyl-phenol under stirring, heating until to 60 degrees C, after total solubilization for approximately 40 minutes, adding remaining (70%) hydrogenated decene homopolymer, stirring until homogenization, for approximately 20 minutes, adding zinc dialkyl phythiophosphate, mixing well for approximately 20 minutes, adding all calcium sulfonate slowly under stirring and maintaining at 90 degrees C for approximately 20 minutes, slowly adding all the acrylate copolymer continuing with stirring for approximately 30 minutes until complete homogenization, and lowering temperature to 60 degrees C and stirring speed to 100 rpm, initiating the addition of all metallic nanoparticles, such as graphene, zinc, sulfur, and/or silver, slowly continuing with stirring, and lowering temperature to 30 degrees C, followed by quality control and storage and/or filling.
