The invention provides a solvent-free long-chain alkane siloxane copolymer and a preparation method thereof, and the copolymer is obtained by carrying out polymerization reaction on high-molecular-weight long-chain olefin, other monomer compounds with unsaturated bond structures and polysiloxane with silicon-hydrogen bonds in a solvent-free state. The polymer obtained through the reaction is matched with different types of resin, the functional master batch can be prepared through processing, internal stress can be reduced, equipment abrasion can be reduced, internal and external lubrication can be enhanced, the service life can be prolonged, comprehensive cost can be greatly reduced, and production efficiency can be improved. The processed and formed material is smooth and moist in surface and good in hand feeling, and the material is endowed with certain waterproof, antifouling and scratch-resistant properties. The material has outstanding advantages in application in the rubber and plastic industry. 本发明提供一
