Abstract

The invention discloses a ternary alloy hyperacoustic motor frictional material of the fire resistance resin modified polyphenyl ester, which solves the low friction coefficient problem, the low impact strength problem, the low abradability problem and the bad processability problem of the prior hyperacoustic motor. The invention is made by 5-25% politef, 5-20% fire resistant resin and the rest polyphenyl, which can also add one or a plurality of 10-35% fortifying fiber, 1-15% metal powder and 1-15% ceramic powder. The invention keeps all the advantages of the present polyphenyl ester plastic alloy hyperacoustic motor frictional material, which is provided with the high friction coefficient, the good abradability, the low noise, the high hardness and the high impact strength.

Description

technical field [0001] The invention relates to a polyphenylene ester (scientific name is polyphenylene p-hydroxybenzoate)-based friction material for an ultrasonic motor, more precisely a polyphenylene ester composite material modified by blending plastics and fillers. Background technique [0002] At present, the commonly used friction materials for ultrasonic motors mainly include sticky friction materials, sticky coating friction materials, coating friction materials and powder metallurgy sintered oily metal friction materials. However, these materials generally have shortcomings such as small friction coefficient, high wear rate, and unstable operation, which cannot fully meet the requirements of ultrasonic motors. The application number is ZL200410043602.1, and the invention name is "polyphenylester plastic alloy ultrasonic motor friction material". It has the characteristics of large stall torque, high speed and low noise; but relatively speaking, it still has a frict...
