Description
Technical field
The present invention relates to a kind of model engineering plastic and production technique thereof, relate in particular to a kind of production technique of nano oxidized samarium modified MC nylon slide block.
Background technology
MC nylon is take hexanolactam as main raw material, under normal pressure, and a kind of model engineering plastic that forms by anionoid polymerization.MC nylon is the various metals material such as instead of copper, aluminium, iron and steel and be widely used in the industries such as weaving, rubber, petrochemical industry, steel rolling, mining machinery, automobile, elevator, lifting machine just progressively.But with the metallographic phase ratio, also there are the shortcomings such as intensity, modulus and heat-drawn wire are lower, water-intake rate is larger, and dimensional stability is relatively poor in MC nylon.
In recent years, active to the research of modified MC nylon both at home and abroad.Common method of modifying mainly is carbon fiber or glass fibre enhancing, particles of inorganic material filling, with other polymkeric substance copolymerization, add organism etc.
The tough-increased and reinforced modification method of plastics is more, and traditional method has blend, copolymerization, use toughner etc.The Inorganic Fillers Filled matrix usually can reduce the goods cost, improve rigidity, thermotolerance and dimensional stability, however the decline that often brings shock strength and tension set.In hard plastic, add the caoutchouc elasticity particle, can improve shock strength, but tensile strength descends.In macromolecular material, add fortifying fibre, can increase substantially its tensile strength, but particularly often to some extent decline of tension set of shock strength.Adopt in recent years liquid crystalline polymers to the original position composite strengthening of macromolecular material etc., the stretching of matrix material and shock strength are all made moderate progress, but elongation at break still descends to some extent.Traditional method of modifying all is that performance take the expendable material aspect is as cost, when increasing the impelling strength of material, the correlated performances such as its tensile strength, rigidity but descend, and when the tensile strength that increases material, rigidity, its toughness is variation but, and attend to one thing and lose sight of another real the genus.
Summary of the invention
The present invention provides a kind of production technique that increases simultaneously the nano oxidized samarium modified MC nylon slide block of toughness and intensity in order to overcome the above problems.
Technical scheme of the present invention is: comprise masterbatch hexanolactam 100 weight parts, nano oxidized samarium 0.5-1.0 weight part, promotor sodium hydroxide 0.12-0.2 weight part, solidifying agent TDI0.3-0.7 liter, solid lubricant molybdenumdisulphide, graphite, boron nitride are respectively 2-3 weight part, 0.5-0.8 weight part, 0.3-0.5 weight part, and concrete production stage is as follows:
1) heating mould: the bed die of mould and patrix are evenly smeared releasing liquid and respectively heating, when treating that the bed die temperature is 145 ℃-180 ℃, when the patrix temperature is 175 ℃-220 ℃, the patrix of mould is installed on the bed die, begin cast;
2) pan feeding: masterbatch hexanolactam 100 weight parts are dropped into molten-bath, connect valve tube and thermometric, the heating and melting still, to below 120 ℃ the hexanolactam of melting begin to vacuumize, the interior pressure of molten-bath this moment is negative pressure 0.08MPa-0.1MPa, close vacuum pump, open purging valve, pull out valve tube, inject nano oxidized samarium 0.5-1.0 weight part, promotor sodium hydroxide 0.12-0.2 weight part, solid lubricant molybdenumdisulphide 2-3 weight part, graphite 0.5-0.8 weight part, boron nitride 0.3-0.5 weight part, connect valve tube, restart vacuum pump and vacuumize and be not less than 1min, the molten-bath temperature maintains 155 ℃-170 ℃;
3) curing molding: the activated molecule with in the solidifying agent TDI injection molten-bath of 0.3-0.7 liter, inject from the die casting mouth, open simultaneously whizzer, centrifugation time is controlled at less than 1-5min, close the whizzer power supply, until the whizzer floral disc is static do not turn after, open the depanning of mold heated case;
4) internal stress is processed: the slide block blank of curing molding is immersed in the water heating vessels, make it in boiling water more than the digestion 3h;
5) mechanical workout: the slide block blank naturally cooling that will process through internal stress, after the blank temperature is cooled to envrionment temperature, by technical specifications machine-shaping.
The advantage of product of the present invention is: nano oxidized samarium particle surface active atomic is many, can combine closely with matrix, and consistency is relatively good.When being subjected to external force, nano oxidized samarium particle is difficult for breaking away from matrix, and because the interaction of stress field produces a lot of little distorted areas in matrix, absorbs a large amount of energy.This can cause matrix yielding again just so that product of the present invention can transmit the external stress of bearing preferably, consumes a large amount of striking energys, thereby obtains to increase simultaneously the effect of toughness of products of the present invention and intensity.
The density of product of the present invention is less only to be 1/7 of steel, and the monomer cast nylon slide block weight of equal volume only is 1/7 of steel casting wheel, and manual assembly is comparatively convenient; High, the good toughness of physical strength, the metal slide blocks such as replacement cast steel that can safety satisfy the requirement of product on using; Abrasion performance, non-skid property are good, and under equal conditions, its friction durability than steel, the high 4-5 of iron doubly; Self-lubricating effect is relatively good, not only saves cost but also saved the man-hour of wasting owing to refueling without hand oiling, and single monomer cast nylon slide block price is cheap more than the steel casting wheel, can bring huge economic benefit to enterprise.
The technique of product of the present invention is taked the centrifugal casting technology, be that mould is placed on the floral disc that is positioned at heating container, floral disc is by the high speed electric machine travel, during cast, open motor, drive floral disc and mould and rotate together, like this, eliminated the internal porosity of product, overcome the steel casting slide block because of its internal porosity and the product quality problem that defective causes such as be mingled with.
