Abstract
The invention discloses a nylon polymer piece water lubricated bearing for ships. Caprolactam is taken as a main component, nanometer level silicon dioxide and titanium dioxide are added into the raw materials, and each component and the usage percentage (weight) thereof are as follows: 94.3-96.5 of caprolactam, 0.3-0.5 of sodium hydroxide, 0.4-0.6 of toluene di-isocyanate, 0.4-0.6 of a molybdenum disulfide, 0.4-0.6 of graphite, 0.6-1.0 of nano-silicon dioxide, 0.2-0.5 of nano-titanium oxide, 0.2-0.4 of scandium oxide, and 1.0-1.5 of zero twist fiberglass yarn. The bearing is used as ship bearing or bushing, each component develops a synergic effect in polymerization, and the density, hardness and wear resistance of the polymer piece are improved, thus improving the performance of the products and prolonging the service life. Furthermore, the polymer piece has the advantages of smooth surface, small friction coefficient, absence of metal powder, lubrication with water only and a wide application.
Description
Technical field
The present invention relates to a kind of bearing for ship, particularly is the water lubricating bearing for ship of material with the nylon polymerization member.
Background technique
Stern bearing peculiar to vessel, rudder bearing and other muff are important boats and ships component, to pressure-bearing, wear-resisting, anticorrosive strict demand arranged.Domesticly used manufacturings such as lignumvitae, bus alloy, white metal in the past, in the application with oil lubrication, the cost of production height, raw material are restricted, are easy to generate pollution.The back is cost an arm and a leg by external import rubber steel part, and deficiency is also arranged on the performance.Recently domestic developing strengthens the resin bearing, Chinese patent ZL991145682 discloses a kind of firm and tough casting of modified nylon for ship, composition based on nylon 6, add glass fibre, rare earth powder and metal powder, technical having made marked progress, but because the powder particles that adds is trickle inadequately, and glass fibre does not limit yet, cause the nylon of making to water foundry goods and be easy to generate bubble, shrinkage porosite, organize fine and closely wovenly inadequately, the surface is smooth inadequately, and wear resistance and tenacity are not good enough, also need in the application, thereby its application is restricted with oil lubrication.
Summary of the invention
The objective of the invention is to overcome the deficiency that existing nylon waters foundry goods, provide a kind of usability good, the life-span is long, with water lubrication, and the nylon polymerization member water lubricating bearing for ship of applied range.
Technological scheme of the present invention is: nylon polymerization member water lubricating bearing for ship, raw materials used is main component with the caprolactam, contain sodium hydroxide, toluene di-isocyanate(TDI), molybdenum disulfide, graphite and glass fibre and rare earth powder, its improvements are: add nano silicon and nano titanium oxide in the raw material, described glass fibre is non-twist glass fiber, described rare earth powder is a scandium oxide, more than the weight percentage of each component in the raw material total amount be:
Caprolactam 94.3～96.5
Sodium hydroxide 0.3～0.5
Toluene di-isocyanate(TDI) 0.4～0.6
Molybdenum disulfide 0.4～0.6
Graphite 0.4～0.6
Nano silicon 0.6～1.0
Nano titanium oxide 0.2～0.5
Scandium oxide 0.2～0.4
Non-twist glass fiber 1.0～1.5
The total amount of above component is 100%.
Described non-twist glass fibre filament diameter is 0.05～0.1mm, and length is 2～10mm.
Nylon polymerization member of the present invention has added nano level silica and titanium dioxide, and it is fine and closely woven that the polymerization part is organized, and can not produce bubble, shrinkage porosite, has improved density, hardness, tenacity and wear resistance, thereby improves product usability and working life.Add scandium oxide rare earth powder and tiny non-twist glass fiber, can make the polymerization part Paint Gloss, strengthen hardness and toughness, friction factor is little, and metal-containing powder not in the polymerization part, only needs in the application with water lubrication, cooling, needn't avoid polluting applied range with oil.Added nanometer particle, rare earth material and glass packing produce synergy in the polymerization part, avoid producing in the polymerization part impurity, damaged, guarantee constant product quality.
Embodiment
Further specify the present invention below by embodiment.
Each amounts of components is listed as follows among the embodiment 1～3:
Each embodiment's operating process is: get component 1,4,5,6,7,8,9 fully put into the head pot after the mixing, the fusion of heating, when reaching 60 ℃, open the vacuum pump suction filtration, behind the decompression dehydration, stop to vacuumize, two pots of vents are opened (two pots of connections), when treating that pot inner pressure returns to barometric pressure, add component 2 toward the head pot, continue to vacuumize, anhydrous and the impurity until fused solution stops vacuum pump and oven, opens head pot top cover, drop into component 3 rapidly, after shaking, immediately fused solution is injected in the mould that is preheating to 165 ℃, carry out the centrifugal polymerization casting, 15～20min finishes polymerization, and the demoulding promptly gets nylon polymerization member behind heat-treatment of annealing again.This polymerization part carries out machining by drawing, makes bearing for ship.
Claims (2)
1, a kind of nylon polymerization member water lubricating bearing for ship, raw materials used is main component with the caprolactam, contain sodium hydroxide, toluene di-isocyanate(TDI), molybdenum disulfide, graphite and glass fibre and rare earth powder, it is characterized in that: add nano silicon and nano titanium oxide in the raw material, described glass fibre is non-twist glass fiber, described rare earth powder is a scandium oxide, more than the weight percentage of each component in the raw material total amount be:
