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 discloses a method for preparing a wind power generation friction drag material. First a mixture of polyetheretherketone, carbon fiber and copper fiber is scattered in absolute ethyl alcohol and then copolymer of magnesium oxide, silicon oxide, lecithin, sodium bicarbonate, sodium sulfoxylate formaldehyde, butyl rubber and ethylene / vinyl acetate is added; heating and stirring are performed, an obtained mixed material undergoes ball milling and drying, finally an obtained dried product undergoes die pressing and heat treatment, and the wind power generation friction drag material is obtained. According to the wind power generation friction drag material, reinforced modification is performed on polyetheretherketone through the introduction of the fibers, and the wind power generation friction drag material has excellent mechanical properties and abrasion resistance.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a preparation method of a friction material for wind power generation. Background technique [0002] Wind power generation is the power generation method with the most mature technology, the most large-scale development conditions and the most promising prospects for commercialization among new energy sources. Because it is non-polluting and renewable, it is known as "clean energy", and it will be one of the key industries in the future. The current cost of power generation is close to that of conventional power generation methods. my country's proven wind energy reserves are about 3226GW, of which the available wind energy is about 253GW, and many wind power plants have been established. However, due to the expensive equipment of wind turbines, the harsh working environment, it is inconvenient to disassemble and repair some key parts on site, and the desig...
