Description

Technical Field

[0001] The invention belongs to the technical field of lubricating products for magic cube care, and specifically relates to a magic cube lubricating additive composition and a preparation method thereof. Background Art

[0002] The Rubik's Cube in the usual sense refers to the three-dimensional Rubik's Cube in a narrow sense. The three-dimensional Rubik's Cube is usually a cube and is made of elastic hard plastic. The conventional racing method is to scramble the Rubik's Cube and then restore it in the shortest time. The Rubik's Cube in a broad sense refers to all kinds of geometric shapes that can be scrambled and restored by rotation. The friction between the contact surfaces of the Rubik's Cube during rotation will reduce the rotation speed of the Rubik's Cube, so the Rubik's Cube lubricant came into being.

[0003] The main function of the Rubik's Cube Lubricant is to reduce the friction when the Rubik's Cube is turned, so that the Rubik's Cube can turn more smoothly and quickly. ‌ Rubik's Cube Lubricant can effectively reduce the friction between the parts of the Rubik's Cube, reduce the rotation resistance, and improve the operability and reaction speed of the Rubik's Cube‌.

[0004] Conventional Rubik's Cube lubricants have an insignificant and short-lasting lubrication effect, which means that the Rubik's Cube needs to be lubricated frequently during use, but the lubrication effect is not obvious, resulting in wear of the contact surface caused by friction, affecting the user experience; and there are only a few types of Rubik's Cubes that are applicable to the lubricant, so it is not universal.

[0005] Chinese patent CN201511010386.5 discloses a new type of long-lasting Rubik's Cube lubricant, which is used for the lubrication and maintenance of the Rubik's Cube. During the rotation of the Rubik's Cube, the long-lasting Rubik's Cube lubricant can evenly flow to the internal contact surface of the Rubik's Cube and form a protective oil film between the friction surfaces to avoid direct contact between the two relatively moving bodies; however, the lubricant still cannot prevent the Rubik's Cube from drying out during use. Summary of the invention

[0006] The technical problem to be solved by the present invention is to provide a magic cube lubricating additive composition, which improves the durability and smoothness of lubricating oil, has a significant effect, and increases the recovery smoothness and stability of the magic cube.

[0008] Furthermore, it also includes 0.5-1% of polyalkyl methacrylate, 0.5-1% of polydimethylsiloxane and 0-1% of oleyl alcohol.

[0009] Furthermore, the base lubricant oil is water-based base oil.

[0010] Furthermore, the extreme pressure agent is one or a combination of sulfurized fatty acid esters, molybdenum disulfide extreme pressure agent, tricresyl phosphate, alkyl phosphite, and ferric chloride.

[0011] Furthermore, the anti-wear agent includes oxidized nano-graphene powder, dialkyl zinc dithiophosphate, tricresyl phosphate, borate and dialkyl molybdenum dithiocarbamate.

[0012] Further, the preparation method of the anti-wear agent is as follows: adding graphene oxide powder to a dimethylacetamide solution, stirring, adding a silane coupling agent, heating and stirring, centrifuging, washing, and drying to obtain modified graphene oxide, and then dispersing it in water, ultrasonically dispersing it, adding hydrazine hydrate, reacting at 80-90° C. for 40-60 minutes, and obtaining a modified graphene solution; Zinc dialkyl dithiophosphate, tricresyl phosphate, borate and molybdenum dialkyl dithiocarbamate are added into the modified graphene solution and stirred to prepare an anti-wear agent.

[0013] Furthermore, the dispersant includes one or more of dimethyl silicone oil, cationic polyacrylamide, calcium sulfonate and monovinyl succinimide.

[0014] Furthermore, the surfactant includes one or more of alkylbenzene sulfonate, alkylphenol salt and petroleum sulfonate.

[0015] The method for preparing a magic cube lubricating additive composition of the present invention is characterized by comprising the following steps: (1) Take base lubricating oil, extreme pressure agent, anti-wear agent, dispersant and surfactant and weigh them for preparation; (2) Preheat the base oil to 25-35°C, add half of the dispersant, and stir and mix in a mixer to form a base liquid of lubricating oil; (3) Add an appropriate amount of additives to the base liquid of the lubricating oil in step (2) and stir evenly; (4) Add extreme pressure agent, anti-wear agent, surfactant and remaining general dispersant to the mixer and mix them with the base fluid thoroughly to make the additives evenly distributed in the lubricating oil; (5) pouring the mixture of step (4) into an ultrasonic stirrer for ultrasonic stirring, controlling the stirring temperature to 50-70°C and the stirring time to 15-20 min; (6) The mixed lubricating oil is cooled to room temperature, and then impurities are removed through a filter to obtain a pure lubricating oil composition.

[0016] The beneficial effects of the present invention are: 1) The lubricating additive composition of the present invention has the dual effects of lubrication and maintenance, improves the durability and smoothness of lubricating oil, has significant effects and outstanding performance, reduces the friction coefficient to 0.05-0.15, and the wear rate is <0.01%; 2) The lubricating additive composition of the present invention can prevent the occurrence of dryness during the use of the Rubik's Cube, increase the smoothness and stability of the restoration of the Rubik's Cube, and increase the restoration speed of the Rubik's Cube by 15%-35%; 3) The use of the lubricating additive composition of the present invention can reduce direct contact between the contact surfaces of the Rubik's Cube, reduce wear and tear, protect the Rubik's Cube for a long time, and maintain the stable feel of the Rubik's Cube for a long time.
