Description
Technical field
The invention belongs to technical field of polymer materials, be specifically related to a kind of preparation method of friction resistance material used for wind power generation.
Background technology
Wind-power electricity generation is the most ripe, the on the largest scale exploit condition of technology and can the generation mode of commercialized development prospect in new forms of energy.Because it is pollution-free, renewable, being described as " the clean energy ", is one of industry of giving priority to of future world, generation current cost and conventional power generation usage mode close.The wind energy content that China has been verified is about 3226GW, wind energy wherein can be utilized to be about 253GW, established Duo Zuo wind power plant.But because of the apparatus expensive of aerogenerator, work under bad environment, on-the-spot inconvenience carries out detachable maintaining to some vital parts, and design requires the work characteristics such as long service life.Rotational inertia due to wind power generator impeller will be far longer than the rotational inertia of generator, and " generator " has stopper to can't resolve problem, so drift stop is mounted on impeller, instead of on generator.The device of impeller, once after installing, as long as have " wind ", will rotate, if when exceeding cut-out wind speed, will stall or deceleration, otherwise will driving.But how " stall or deceleration " is a problem that must solve, and the brake facing therefore for impeller arises at the historic moment.Impeller turn degree unhappy (blower fan of 600 kilowatts is generally 27 revs/min) therefore slow down or stall time temperature can not acutely raise, the polyether-ether-ketone matrix requirement as blower fan friction resistance material caking agent that can meet under this operating mode for this reason, and the most of dependence on import of friction resistance material on current China blower fan.
Friction resistance material is mainly used in movable machinery and equipment, plays braking, transmission, turns to, slows down, the effect such as parking, and any mechanical means of doing relative motion and various vehicle all must be installed and brake or transmission mechanism.As the critical piece on braking or transmission mechanism, friction resistance material mainly utilizes self good tribological property, be energy based on heat energy by kinetic energy during braking to frictionally, thus reaching the effect of braking, its topmost function absorbs by rubbing and transmits power.As brake facing absorbs kinetic energy and clutch disc transmission power etc., can ensure that moving parts works safely and reliably.
At present, material composition design remains the main direction of studying of friction resistance material, and the method adopted in experimental study is diversified, and its object is also for the purpose of the properties strengthening New Friction Material.Along with the fast development of science and technology, the development of novel material, must promote that friction resistance material has multiple choices in technique and formulating, thus develops the friction resistance material that can adapt to and meet different operating mode.In friction resistance material moiety, Single Fiber as some shortcoming of strongthener, such as: carbon fiber properties is good, but cost is higher, limits popularization; Glass fibre due to smooth surface, can not well and matrix binder infiltrate, thus both is undesirable in conjunction with effect; Steel fiber easily gets rusty the problems such as inefficacy.At present, assorted fibre strengthens and becomes the first-selection of investigator, for example glass fibre and steel fiber, carbon fiber is used to mix with copper fiber and steel fiber and carbon fiber etc. in Semi-metal Friction Materials, utilize the advantage of different fiber, properties can be met simultaneously, develop the friction resistance material that cost performance is high.Therefore, assorted fibre enhancing friction resistance material is still one of modern research direction.
