Abstract
The present invention provides embedding self-lubricating composite material. The composite material is suitable to be used under a temperature ranging from room temperature to 300DEGC, has excellent resistance against extreme pressure, and is composed of a metal substrate and a solid lubricant paste embedded into the metal substrate. The present invention is characterized in that the solid lubricant paste can be embedded in the holes, the grooves or the concave parts in other forms of the substrate; cohesive material contained in the solid lubricant paste is processed by chemical modification; two kinds of solidifying agents are adopted, and solid and liquid are mixed thoroughly; therefore, the solid lubricant after solidification has a high intensity and good transitivity. The embedding self-lubricating composite material is applicable to the lubrication of rubbing pairs under the conditions of overweight load, low speed, large dust capacity, corrosive media, etc.; the application of the present invention in the large-scale mechanical equipment of building, the smelting of colored iron and steel, the petrochemical industry, architecture and other industries can conspicuously reduce friction and abrasion, and greatly prolong the service life of the mechanical equipment.
Description
The present invention relates to mosaic self-lubricating composite material of a kind of high temperature resistant anti-extreme pressure and preparation method thereof.
Because the requirement of special producing technology, some key equipment of large industrial enterprise must move under very abominable operating mode, for example Lian Gang converter, electric furnace, the rotary kiln of nonferrous smelting, electric furnace, scraper plate chain conveyor, the horizontal revolving kiln of cement manufacturing etc.Because equipment is heavy, the envrionment temperature height, dust is many (also to contain acid attack gas CO, SO in the air that has
2Deng), that gives equipment lubricatedly brings a lot of problems.So far, domestic above-mentioned enterprise major part is still continued to use traditional oil, grease lubrication, but in fact these operating modes have exceeded use range oily, fat, and the heavy wear of bearing and other friction pair very easily takes place, and cause equipment to be stopped transport.For the continuous operation that guarantees to produce, except that just requiring in design to install the multiple devices wheel repaiies, also dropped into a large amount of servicemans, spare parts and energy consumption are serious.
The objective of the invention is in order to solve industry big machineries such as metallurgy, building materials, petrochemical complex heavy wear problem during operation under overweight load, lower velocity, high temperature, big Dust Capacity and corrosive medium, reduce the energy and a large amount of losses of starting material that cause thus, a kind of mosaic self-lubricating composite material and preparation method thereof is provided.
Mosaic self-lubricating composite material is a kind of high temperature resistant anti-extreme pressure solid lubricant.Its constitutional features is boring or a fluting on the surface of friction of metal substrate, embeds the solid lubricant lotion with good self-lubricating property then.It is strong that inlaid material has supporting capacity, use temperature height (normal temperature～300 ℃), characteristics such as shock resistance is good, and is strong to severe environment adaptability such as dust, corrosive gases, the width of cloth shine, and friction durability is long.Can be made into bearing, lining, slide plate (ring), the use of guide plate component such as (rails).Available metal substrate has bronze, brass, cast iron etc.It can use separately, realizes oil-free lubricatoin, also can and use with grease.Inlaid material replaces oil, grease lubrication, has overcome latter's oil film and has broken easily, causes the disadvantage of component rapid wearing.Be particularly useful for heavy duty, low speed intermittence or the continuous operating mode of moving down, can prolong service life of equipment significantly, stop greasy leakage.
The present invention is made up of the solid lubricant lotion of metal substrate and embedding metal substrate.
The solid lubricant lotion is a binding agent with the F44 novolac epoxy, and end carboxyl liquid fourth eyeball 40 is the binder modification agent, and pyromellitic acid dianhydride and Tetra hydro Phthalic anhydride are solidifying agent, graphite, tetrafluoroethylene and MoS
