Abstract
The invention provides a method for preparing a yaw friction plate of a wind driven generator from tetra-needle like zinc oxide whiskers. The yaw friction plate is prepared from the following raw materials in part by weight: 5 to 8 parts of adhesive, 20 to 28 parts of reinforcing fiber, 15 to 32 parts of abrasive, 9 to 15 parts of lubricating agent and 25 to 40 parts of regulator, wherein the adhesive is one or a combination of more of phenolic resin, nitrile -butadiene rubber modified phenolic resin and silicon modified phenolic resin; the reinforcing fiber is one or a combination of more of a copper-cotton fiber, an organic fiber and a mineral fiber; the abrasive is one or a combination of more of zirconium silicate, iron black, barium sulfate and calcium carbonate; the lubricating agent is one or a combination of more of an inorganic lubricating agent, an organic lubricating agent and metal sulphide; and the regulator is one or a combination of more of tetra-needle like zinc oxide whiskers, magnesium oxide and friction powder. In the method, the unique tetra-needle like three-dimensional structures of the tetra-needle like zinc oxide whiskers are uniformly distributed in a matrix material so as to isotropically improve physical properties of the material and endow the material with various unique functional characteristics. Therefore, the overall performance of the friction plate is changed, the friction noise is radically eliminated and the strength of the material is improved.
Description
Technical field the present invention relates to new energy field, particularly the preparation method of wind driven generator yaw friction plate.
Background technology is along with development of global economy, also develop rapidly of new forms of energy industry, and wherein wind energy more and more is subjected to the attention of countries in the world as a kind of renewable energy source of cleaning, and wind energy market also develops rapidly.Aerogenerator is the power machine that wind energy is converted to mechanical energy, and what it utilized is natural energy resources, does not have fuel problem, also can not produce radiation or atmospheric pollution, has now become the emphasis of new forms of energy development.
During wind turbine power generation, need adjust the direction of blade, with the vanes fixed of aerogenerator direction, so that wind wheel obtains maximum wind energy towards the wind-force maximum because of the change of wind-force direction.Yaw system plays a part to adjust the blade of wind-driven generator direction, and the driftage friction plate is a main accessory of yaw system.Because wind-power electricity generation developed rapidly in recent years in China, the power of generator promotes to 3MW, 5MW from 0.75MW, 1.5MW, and this friction plate that just requires to go off course not only has good braking effect, and also will be arranged long work-ing life, high compression strength, no friction noise.The primary structure of driftage friction plate is cakingagent, fortifying fibre, abrasive, lubricant and necessary conditioning agent at present, and the present ubiquitous problem of this friction plate influences complete machine and normally uses for serious for friction noise.
Summary of the invention the purpose of this invention is to provide the method that a kind of four acicular type zinc oxide crystal whisker prepares the wind driven generator yaw friction plate, and the driftage friction plate of this method preparation has improved the overall performance of matrix material, and emphasis solves the friction noise problem.
Material used in the present invention is formed as following weight percent: tackiness agent 5-8, fortifying fibre 20-28, abrasive 15-32, lubricant 9-15, conditioning agent 25-40, tackiness agent wherein comprise the one or more combination of resol, nbr modified phenolic resins, silicon modified phenolic resins; Fortifying fibre comprises the one or more combination of copper cotton fibre, organic fibre, mineral fibre; Abrasive comprises the one or more combination of zirconium silicate, iron oxide black, barium sulfate, lime carbonate; Lubricant comprises the one or more combination of inorganic lubricant, organic lubricant, metallic sulfide; Conditioning agent is the one or more combination of four acicular type zinc oxide crystal whisker, magnesium oxide, friction powder.
The present invention compared with prior art, its advantage is: the solid four needle-like three-dimensional structures of utilizing the four acicular type zinc oxide crystal whisker uniqueness, be implemented in the uniform distribution in the body material, thereby isotropically improve the physicals of material, give the functional performance of the multiple uniqueness of material simultaneously.As wear-resisting, enhancing, vibration damping, anti-skidding, noise reduction, suction ripple, performance such as anti-aging, antistatic, antibiotic, to change the overall performance of friction plate, eliminate friction noise fully, improve the intensity of material simultaneously.
