Abstract

The invention belongs to the technical field of wear-resistant materials, and discloses a wear-resistant composite material with a high friction coefficient and a preparation method thereof. The wear-resistant composite material is mainly technically characterized by comprising the following raw materials in parts by weight: 10-30 parts of high-density polyethylene, 30-50 parts of ultra-high molecular weight polyethylene, 10-20 parts of cross-linked rubber powder, 0.1-0.5 part of an antioxidant 1010, 5-20 parts of inorganic powder, and 1-5 parts of carbon black. According to the wear-resistant composite material with the high friction coefficient, provided by the invention, all the components are mixed into pellets by using an internal mixer, then, the compression molding is carried out, and the machinability of the high-density polyethylene, the wear resistance of the ultra-high molecular weight polyethylene, and the high friction coefficient of the cross-linked rubber powder are fully utilized, so that the composite material with a high dynamic friction coefficient, good wear resistance and higher strength is obtained; the wear-resistant composite material with the high friction coefficient is prepared by adopting an internal mixing technology, and leftover materials can be recycled, so that environment friendliness is achieved.

Description

technical field [0001] The invention belongs to the technical field of wear-resistant materials, and in particular relates to a wear-resistant composite material with a high friction coefficient used in a bridge shock-absorbing and isolating device and a preparation method thereof. Background technique [0002] Seismic isolation, in literal terms, is to isolate the effects of earthquakes. Its essence and purpose is to isolate the structure as much as possible from ground movements that could cause damage. Shock absorption, literally, means reducing seismic energy. Its essence and purpose is that under the action of moderate earthquakes, major earthquakes and strong earthquakes, the energy-dissipating elements first enter the energy-dissipating working state, generate greater damping, dissipate a large amount of earthquake energy input into the structure, and quickly attenuate the dynamic response of the structure. And the main structure does not appear obvious inelastic de...
