Problems solved by technology

In terms of the composition of friction materials, a single fiber has some disadvantages as a reinforcing material, such as: carbon fiber has good performance, but its cost is high, which limits its promotion; glass fiber cannot be well infiltrated with the matrix binder due to its smooth surface. Therefore, the combination effect of the two is not ideal; the steel fiber is prone to rust and failure.

Abstract

The invention relates to a high-strength friction-resistant material for blowers. The high-strength friction-resistant material for blowers comprises a friction-resistant material matrix and a high-strength system, wherein the high-strength system accounts for 17-19 wt% of the friction-resistant material matrix. The friction-resistant material matrix comprises the following components in parts by weight: 21-23 parts of polyetheretherketone, 9.2-9.4 parts of carbon fiber, 132-134 parts of anhydrous ethanol, 6.1-6.3 parts of magnesium oxide, 7.2-7.4 parts of magnesium chloride, 1.7-1.9 parts of lecithin, 6.5-6.7 parts of sodium bicarbonate, 6.4-6.6 parts of sodium sulfoxylate formaldehyde, 1.7-1.9 parts of butyl rubber and 6.5-6.7 parts of ethylene-vinyl acetate copolymer. The impact strength, mechanical properties, friction factor, high temperature resistance and antistatic property of the friction-resistant material can be enhanced.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a high-strength friction material for a fan. Background technique [0002] Friction materials are mainly used in sports machinery and equipment to play the role of braking, transmission, steering, deceleration, parking, etc. Any mechanical equipment and various vehicles that do relative motion must be equipped with braking or transmission devices. As a key part of the braking or transmission device, the friction material mainly uses its own good tribological properties to convert the kinetic energy during braking into energy mainly heat energy in the form of friction, so as to achieve the effect of braking. , its main function is to absorb and transmit power through friction. For example, brake pads absorb kinetic energy and clutch plates transmit power, etc., which can ensure the safe and reliable operation of moving parts. [0003] At present, material c...
