Description
Technical field
The invention belongs to field of new, relate to a kind of alternative virgin iron pear wood and prepare stern journal bearing of ship, substitute iron/copper-base powder metallurgy oil-containing sliding bearing material and prepare the field electromechanical equipment sliding surface bearing such as food, medical treatment, weaving, substitute redwood and ox bone and prepare artificial rock wood of high-grade automotive upholstery and preparation method thereof.
Background technology
At present, human exploitation for forest, oil and all kinds of mining depositses has been arrived mad stage with predation; Dig environmental pollution, climatic deterioration and the secondary disaster of bringing and adopt unrest for the excessive and random lumbering of forest and for the unrest of oil and mineral reserve, beaten alarm bell to the mankind already; So people begin to consider how to reduce the degree of dependence for forest, oil and all kinds of mining depositses.Although being effective utilization of forest and agricultural biomass (comprising forestry and bamboo logging residue, saw lumber residuum, industrial wood waste and agricultural crop straw, shell, reed stalk etc.), the rise of the industries such as wood-based plate brought into play very large effect, but wood-based plate is from being fabricated onto use, because the release of free formaldehyde, most artificial boards all exist problem of environmental pollution to some extent, and by volume valency, catchpenny industry professional etiquette and management mode so that the production technology of the sector and goods are basic and high-quality, the industrial application of high added value for no reason at all.
Rock wood is because its material is firmly heavy, tough, light is gorgeous, anti-corruption, anti-moth are gained the name, all make the virgin iron pear wood countries in the world as the water lubricated ship tail bearing important materials is for simplifying the parts of bearings structure, avoiding lubricating oil that river seawater matter is polluted having made distinctions won on the battlefield.Yet China is used for the main dependence on import of rock wood that stern journal bearing of ship is made, and is not only expensive, and have the defective such as anisotropy because the virgin iron pear wood is the same with other natural timber, and quality product often also is difficult to assurance.So scientific and technical personnel have developed the water lubricating bearing material take the lamination bakelite as representative, attempt to substitute the virgin iron pear wood, but still there is anisotropy in the lamination bakelite, causes use procedure to pay the cost of blood.
In addition, be widely used at present copper base or ferrous based powder metallurgical sintering antifriction material that the field electromechanical equipments such as food, medical treatment, weaving are made with sliding surface bearing, saved the fuellers such as malthoid, lubricating cup because utilizing its porosity characteristic to contain self-lubricating oil; No matter but copper base or ferrous based powder metallurgical agglomerated material, it is high not only to rely on metal mineral reserves and petroleum product, price fully, and also can bring more or less pollution to food, medicine and fabric.
Moreover, bring out accommodating and medium-to-high grade automobile comfort to people, be installed in the panel board, handle, saucer, panel of wheel house etc., its material mostly is greatly ox bone, redwood etc., and the costliness of rare, the price of resource is known by everybody.
Can innovate a kind of green manufacturing technique, the forest and agricultural biomass of high-quality clean utilization cheapness is prepared material as the virgin iron pear wood, firmly heavy as the ox bone, tough, light is gorgeous, wear-resisting, isotropy, color is adjustable, artificial rock wood with self-lubricating property, be used for substituting the stern journal bearing of ship that the preparation of virgin iron pear wood adapts to the water lubricating environment, substitute the power metallurgical oil-retaining material for sliding bearing and prepare food, medical treatment, the field such as weaving electromechanical equipment is with sliding surface bearing that need not immersion lubrication oil, substitute ox bone, redwood prepares the panel board of automobile cab, handle, saucer and panel etc., allow people's future life, when enjoying the high performance-price ratio treatment, reduce to a certain extent for forest, the degree of dependence of oil and all kinds of mining depositses? the present invention has answered matrix material and this problem demanding prompt solution of biomass field of functional materials for certain by careful design and test.
