Abstract

The invention belongs to the technical field of wear-resistant materials, and specifically discloses a composite wear-resistant material for sucker rod elevators and a preparation method thereof. The wear-resistant material includes the following raw materials in parts by weight: 15-20 parts of kaolin, 2-3 parts of carbonized Boron, 2-3 parts of silicon carbide, 2-3 parts of silicon nitride, 55-70 parts of rubber, 1-2 parts of graphene, 3-5 parts of carbon fiber, 3-4 parts of antioxidant, 1-2 parts of coupling agent, 1 to 2 parts of crosslinking agent, and 3 to 5 parts of modifier. The wear-resistant material of the present invention has good mechanical properties, high temperature resistance and wear resistance. The sucker rod elevator made of this material can replace the existing metal elevator, and change the hard clamping of the traditional metal elevator into a soft one. Clamping makes up for the defects of the existing metal elevators, avoids knocking, bumping, smashing and other damage to the sucker rod during the lifting and lowering operation of the sucker rod, thereby prolonging the service life of the sucker rod.

Description

technical field [0001] The invention relates to the technical field of wear-resistant materials, in particular to a composite wear-resistant material for sucker rod elevators and a preparation method thereof. Background technique [0002] The elevator is an essential tool for oil drilling operations. When carrying out drilling operations, sucker rod elevators must be used for lifting and lowering the sucker rod. The traditional sucker rod elevators are mostly made of metal. In the process of use, if the staff is negligent, there may be accidents of knocking, bumping and smashing the sucker rod, causing damage to the sucker rod and affecting the use of the sucker rod life. Contents of the invention [0003] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a composite wear-resistant material for sucker rod elevators and a preparation method thereof, which are used to make up for the defects of existing metal e...
