Abstract

The invention discloses a conductive wear-resistant quakeproof equipment pad material and a preparation method thereof and belongs to the technical field of preparation of pad materials. The conductive wear-resistant quakeproof equipment pad material is made from TPU (thermoplastic polyurethane), stainless steel powder, graphite powder, an antioxidant, a dispersant, nano titanium carbide, nano tungsten carbide, and tungsten powder by: mixing, extruding, cooling, pelletizing and other steps; by using the preparation method herein, tensile strength and elongation of the material can be significantly improved; the material of the invention is widely applicable to precision instrument pads, equipment pads producing static electricity by friction and the like.

Description

technical field [0001] The invention belongs to the technical field of foot pad material preparation, and in particular relates to a conductive wear-resistant shockproof equipment foot pad material and a preparation method thereof. Background technique [0002] Rubber has good comprehensive properties, such as high adhesion to metal, mechanical properties, fatigue properties, aging resistance, and low heat generation. Rubber foot pad materials are used in various industries, but rubber foot pad material foot pads The anti-shock effect is poor, the vibration equipment is noisy, and the rubber and plastic material foot pads are easy to cause static electricity accumulation in the equipment due to insulation, causing safety hazards, and there is no double insurance if the ground wire is completely conducted by the equipment ground wire. Therefore there is an urgent need for a high-performance conductive wear-resistant shockproof equipment foot pad material. [0003] The Chines...
