Abstract

The invention discloses a high-strength cold-resistant aramid fiber synchronous belt which comprises a synchronous belt framework and a synchronous belt rubber sheet attached to the outer face of the synchronous belt framework in a wrapping mode. The synchronous belt rubber sheet is prepared from the following raw materials in parts by weight: 10-15 parts of aramid short fibers, 2-4 parts of phosphorus pentoxide, 1-3 parts of polyphosphoric acid, 6-8 parts of 2-acrylamido-2-methylpropanesulfonic acid, 60-70 parts of methyl vinyl phenyl silicone rubber, 2-5 parts of an initiator, 3-5 parts of a coupling agent, 3-5 parts of nano boron fibers, 10-20 parts of an inorganic filler and N-(N-(2-acrylamido-2-methylpropanesulfonic acid)). 2 to 5 parts of 4-cyano-3-trifluoromethylphenyl) methacrylamide, 10 to 20 parts of a polyether polyamide elastomer and 1 to 3 parts of an anti-aging agent. The invention further discloses a preparation method of the high-strength cold-resistant aramid fiber synchronous belt. The high-strength cold-resistant aramid fiber synchronous belt is high in strength, sufficient in cold resistance, good in aging resistance and heat resistance and long in service life.

Description

technical field [0001] The invention relates to the technical field of synchronous belts, in particular to a high-strength cold-resistant aramid fiber synchronous belt and a preparation method thereof. Background technique [0002] The synchronous belt is an annular belt with equidistant teeth on the inner peripheral surface. When rotating, the power is transmitted through the meshing of the belt teeth and the tooth grooves of the gears. Synchronous belt combines the advantages of belt drive, chain drive and gear drive. It has the advantages of high transmission efficiency, accurate transmission ratio, wide transmission ratio range, stable transmission, small force on the shaft, low noise, energy saving, etc. It is widely used in Textile, machine tools, tobacco, communication cables, light industry, chemical industry, metallurgy, instrumentation, food, mining, petroleum, automobiles and other industries of various types of mechanical transmission. [0003] The main rubber m...
