Description
Technical field: the present invention relates to a kind of bearing materials, particularly a kind ofly be used for that screw shaft of ship holds and the modified thermoplastic resin bearing materials of rudder bearing.
Background technology: monomer cast nylon (MC nylon) also claims monomer cast nylon, chemical name is a hexanolactam, be a kind of engineering plastics of excellent property, but the MC nylon of non-modified exists wear resistance in actual applications and self lubricity is not good enough, wear rate is big, dimensional stability and the not high shortcoming of thermostability.Limited the widespread use of MC nylon products.Along with the development of modern science and technology and practical application, people have higher requirement to the MC nylon material, so, the research of the various modifications of MC nylon is become heat subject.
Engineering plastics use 2003 (9), 63-66 has introduced " present Research of modified cast mylon and development trend ", the nylon nano matrix material of wherein mentioning the exploitation of U.S. RTP plastics compounding company is to adopt a kind of special compounding method, adds the organic clay mixture of 3%-5% in nylon.The shock strength of this matrix material and nylon 6 are approaching, and heat-drawn wire can improve 53%, and tensile strength has improved 63%.Plastics industry 2003 (12), 31-65 has introduced " research of MC nylon/nano calcium carbonate composite material optimal preparation technology ", by adding nano-calcium carbonate, makes tensile strength of material reach 73.3MPa, and tension set is 33.3%.Chinese patent application CN1323848 has introduced a kind of rare earth modified cast mylon preparing process, and its base-material is a MC nylon, chemistry hexanolactam by name, and its tensile strength is 100Mpa, water-absorbent 0.07%, notched Izod impact strength 570KJ/m
2, frictional coefficient 0.10.
Bearing for ship is very high to material requirements, requirement possesses very high compressive strength, higher resistance to impact shock, wear resistance is good, and frictional coefficient is low, along with the development of material industry, adopt organic materials alternative metals material to become a kind of trend, the main dependence on import of modified resin bearing for a long time, main body entrance be Canada " match dragon " bearing for ship, cost is very high.In order to reduce cost, Chinese patent 98122098.3 has been introduced " a kind of method and prescription thereof for preparing high molecular oil-imprenated bearing ", but from its test data, its bearing capacity, wear resistance and frictional coefficient are also undesirable.
Summary of the invention: the purpose of this invention is to provide a kind of have high bearing capacity, high abrasion resistance, modified thermoplastic resin bearing materials that frictional coefficient is little.Technical scheme of the present invention is: modified thermoplastic resin bearing materials, and the weight part of its moiety is:
Hexanolactam 100
Nano grade carbon black 1-3
High temperature oil 2-4
Sodium hydroxide 0.12-0.5
αYang Hualv 0-2
Rare earth 0.02-0.2
Toluene diisocyanate 0.3-0.5
Above-mentioned rare earth is one or more of lanthanide series rare-earth elements or its compound.The particle diameter of carbon black is 20-40nm.
Its preparation technology is: fusing base-material hexanolactam, add nano grade carbon black, high temperature oil, αYang Hualv, rare earth respectively by proportioning then in good time, make its thorough mixing, after adding catalyzer sodium hydroxide, vacuumize, dewater, add the polymerizing agent toluene diisocyanate, carry out the thermopolymerization moulding again, heat-treat at last, further improve intensity and impelling strength.
The invention has the beneficial effects as follows: the additive of nano material has been selected nano grade carbon black for use, when increasing oil absorbency, improved the performance of material greatly, the adding of rare earth simultaneously, improved the over-all properties of material greatly, shock strength, wear resistance obtain to improve, frictional coefficient and water-absorbent reduce, and particularly the compressive strength of bearing materials and modulus of compression significantly improve.Compressive strength reaches 133Mpa, and modulus of compression reaches 3580Mpa.Cost of the present invention also is significantly less than imported product, fully can import substitutes and participate in the competition of world market.
