Description
The present invention relates to a kind of hexanolactam that is used to make stern bearing of ship is the polymkeric substance of base-material.
Existing stern bearing of ship, its lubricating system have two kinds of oil lubrication and water lubricatings, the wherein stern bearing of oil lubrication, must dispose stern shaft seal gland on the structure, it is the stern tube shaft structure complicated not only, and be difficult to guarantee no-leak, harm naval vessel disguised and contaminative and contaminate environment; For this reason, the stern bearing of water lubricating is paid attention to for people day by day, both can avoid the waters to suffer oil pollution, can improve the naval vessel disguise again; But the gordian technique of Water Lubricated Stern Tube Bearing System is the selection of bearing materials, in early days, select for use rock wood as the stern bearing material, it is respond well, but can't tie up and continue along with the exhausted day by day of this timber resources, generation and the rubber-supporting bearing of usefulness, though price is not high, but its supporting capacity is lower, easy wearing out, thereby also is difficult to obtain to be extensive use of.
Along with development of technology, stern bearing adopts macromolecular material, paid attention to by the people, wherein Canada's match dragon (THORDON) bearing company has obtained than much progress, still aspect the research non-metallic elastic material, it is not enough that the type stern bearing is still disliked at aspects such as resistance to impact shock and elongation at break, physical strengths, especially its abrasion characteristic is relatively poor, and is bigger to the damage of naval vessel stern tube shaft, then is the anxious improved problem for the treatment of.
The objective of the invention is to provide a kind of improved high-molecular material for stern bearing of ship, it can adapt to the water lubricating operating mode, have high impulse strength and elongation at break and physical strength again, have excellent friction wearing character and low-temperature performance to satisfy particular surroundings and bad working environments requirement.
For achieving the above object, high-molecular material for stern bearing of ship includes the caprolactam monomer (A) of 95～60% (weight percentage), long-chain activator (B) with 5～40% (weight percentage), and add (A) and (B) 0.23～0.30% (weight percentage) sodium hydroxide of total amount, 0.02～0.05% (weight percentage) nucleating agent that adds (A) total amount again, and add (A) and (B) 2～3 (weight percentage) oil cpd of total amount.
Long-chain activator (B) can be polyether-type or polyester type, and nucleating agent can be phthalocyanine blue or carbon black, and oil cpd can be pure machinery oil, white oil or diffusion pump oil and adds tensio-active agent.
Caprolactam monomer of the present invention is the base-material of block interpolymers, its long-chain activator can account for block interpolymers, directly cause the anionoid polymerization of hexanolactam, the segmented copolymer of synthesis of caprolactam/polyethers or polyester, this multipolymer is provided the intensity of material by the hexanolactam hard segment, rigidity, modulus, fusing point, degree of crystallinity etc., and provide the impact of material by polyethers or soft polyester segment, flexible, low-temperature performance etc., the characteristics that high-molecular material for stern bearing had couple hardness with softness, the sodium hydroxide of its interpolation then can be selected the polymerization degree of its consumption control material, so that it is under the different operating condition, keep the stable of product properties, the adding of nucleating agent then can improve the normal temperature performance of material, the interpolation of its oil cpd, can reduce the frictional coefficient of material, reduce wearing and tearing, and improve the wear resistance of material simultaneously stern tube shaft, reduce water-intake rate, improve product size stability, also can improve the heat-drawn wire of bearing, thereby make it become the ideal material of stern bearing of ship.
Below in conjunction with embodiment and accompanying drawing thereof the present invention is described in further detail.
Fig. 1 is the schema of the embodiment of the invention.
Fig. 2 is the schema of further embodiment of this invention.
High-molecular material for stern bearing of ship of the present invention includes:
Base-material, caprolactam monomer (A), content are 95～60% (percetages by weight), it is Technical grade white powder or flaky crystal body, feel oiliness, the organic solvent such as soluble in water or ethanol;
The long-chain activator includes polyether-type long-chain activator or polyester-type long-chain activator, is breast White is block, moisture-sensitive, and the long-chain activator forms block interpolymers, and it directly causes base-material in oneself The anionic polymerisation of amide monomer, the segmented copolymer of synthesis of caprolactam/polyethers or polyester, this Kind of copolymer provides the intensity of high-molecular material for stern bearing of ship, just by the caprolactam hard segment Degree, modulus, fusing point, degree of crystallinity etc., and the shock resistance of material is provided by polyethers or soft polyester segment Property, pliability, cryogenic property etc., thereby, make the multiblock of caprolactam/polyethers or polyester Thing has the advantages that to couple hardness with softness;
The content of long-chain activator is to the impact (dry state) of EVA mechanical property, and is as shown in the table:From table, can know and find out, along with the increase of long-chain activator content in EVA, material Hardness and hot strength reduce, and elongation at break and impact strength strengthen; Obviously, naval vessel stern tube shaft Hold and use macromolecular material, can utilize the long-chain activator to provide the addition of soft chain segment to regulate, in the hope of reaching To the required optimum performance of actual condition;
The content of long-chain activator is as shown in the table to the impact of EVA hot property:
From table, can know and find out, along with soft segment content increases, the fusing point of block interpolymers, crystallization Degree reduces gradually, namely introduce soft chain segment after, shared part of rate of caprolactam descends copolymer degree of crystallinity Reduce, caprolactam crystallization solid particles is converted to decentralized photo by continuous phase, has lost supporting role; Along with increasing of soft chain segment, sub-chain motion and the easier realization of interchain slippage, therefore, its dimension card is softening Point also constantly reduces;
Sodium hydroxide, its addition are 0.23～0.30% (weight percentage) of caprolactam monomer (A) and long-chain activator (B) total amount, and the Working environment humidity of the visual preparation of its consumption is chosen.
Nucleating agent, can select phthalocyanine blue or carbon black for use, its addition is 0.02～0.05% (weight percentage) of caprolactam monomer (A) total amount, the spherocrystal diameter of caprolactam polymerization body can reduce with the increase of nucleating agent addition, the particle diameter of nucleating agent then should be controlled and be not more than 10 μ m, the adding of phthalocyanine blue can improve the normal temperature performance of high-molecular material for stern bearing of ship; When taking carbon black when doing nucleating agent, can be mixed with black color paste together with HMPA and use, the ratio of the two is that carbon black is that 1 HMPA is 3;
