The invention discloses a lubricating oil special for a motorcycle engine, and belongs to the technical field of lubricating oil. The lubricating oil is obtained through a reaction carried out on 80 parts to 90 parts of base oil, 2 parts to 5 parts of abrasion resistance agents, 5 parts to 10 parts of corrosion resistance agents, 2 parts to 5 parts of cleaning factors, 5 parts to 15 parts of antioxidant, 1 part to 3 parts of metal deactivator and 8 parts to 12 parts of viscosity modifier. The base oil is composed of 30 parts to 40 parts of PAO and 40 parts to 50 parts of naphthenic base oil. The cleaning factors are any one of metal-based sodium or metal-based calcium or metal-based magnesium. The invention further discloses a preparing method of the lubricating oil. According to the lubricating oil special for the motorcycle engine, the cost of the base oil is controlled, and the better viscosity index and the high abrasion resistance performance can be ensured at the same time; viscous black carbon mud particles wrapped on engine parts can be effectively removed through matched addition of auxiliaries, the service life of the engine is prolonged, the equipment maintenance cost is reduced, and the clean abrasion protection mode is provided for the motorcycle engine. The preparing method of the lubricating oil is simple in steps, environmentally friendly, and easy to implement.

The present invention is directed to polymer blend compositions for use as viscosity modifiers comprising at least two ethylene-based copolymer components. The viscosity modifiers described herein comprise a first ethylene-based copolymer having an ethylene content of from about 44 to about 52 wt % and / or a heat of fusion of from about 0 to about 15 J / g and a second ethylene-based copolymer having an ethylene content of from about 68 to about 75 wt % and / or a heat of fusion of from about 40 to about 65 J / g. The invention is also directed to lubricant compositions comprising a lubricating basestock and a polymer blend of the invention.

The invention provides an aluminum button and a preparation method thereof. The aluminum texture effect of the button is improved through simultaneous adjustment and mutual cooperation of the button blank and the finish paint of the button, specifically, for the button blank, a certain amount of FX-218 flexible resin liquid is matched with an unsaturated resin base material, and meanwhile, methylethyl ketone, cobalt salt and a viscosity modifier are matched to prepare the button blank; for the finish paint, polyurethane resin and acetate fiber resin are used as main components in the main paint; electroplating silver paste of a certain specification is added, then a leveling agent and a solvent are matched to be combined with the button blank, the aluminum texture effect can be improved,the aluminum oxide effect similarity of 90% or above can be achieved, the firmness combination of the button blank and finish paint is optimal, and meanwhile, the aluminum button meets the industrialstandard requirements for abrasion resistance, washing resistance, solvent resistance and the like.
