Abstract

Provided are a composite material-based elastic suspender and a preparation method thereof. The elastic suspender comprises the following raw materials of: in parts by weight, 54-92 parts of polypropylene, 8-22 parts of nano nitrile rubber powder, 8-22 parts of activated aluminum hydroxide, 10-16 parts of mica powder, 0.02-0.16 part of 3-glycidyl etheroxy propyl trimethoxy silane, 0.08-0.24 part of N-aminoethyl-gamma-aminopropyltriethoxysilane and 0.02-0.16 part of N-(beta-aminoethyl)-gamma-aminopropyl trimetoxy(triethoxy) silane. The defect that a suspender with a tensile strength of less than 80 MPa and an impact toughness of less than 92 J in the prior art is far from adapting to occasions with high requirements for tensile strength and impact toughness is overcome effectively.

Description

technical field [0001] The invention relates to the technical field of elastic slings, in particular to an elastic sling based on composite materials and a preparation method. Background technique [0002] In material handling machinery, wire ropes are often used for lifting, pulling, tensioning and carrying. The steel wire rope is generally twisted into strands by multi-layer steel wires, and then centered on the rope core, a certain number of strands are twisted into a helical shape. However, in actual use, the steel wire rope is prone to defects such as non-shock absorption, corrosion, aging, and electrical conductivity, which can easily cause safety hazards. At the same time, the overall steel wire rope is relatively bulky, and it is easy to scratch the hanging object, which affects the shape of the hanging object. aesthetics. [0003] Since the first synthetic fiber sling was successfully used in the field of industrial hoisting in the United States in 1955, it has be...
