Abstract
The invention relates to an organic polymer composite material, more specifically, in particular to self-lubricating abrasion-resistant injection-molding grade nylon 66 and a preparation technology thereof. The self-lubricating abrasion-resistant injection-molding grade nylon 66 comprises the following components according to weight ratio: 49.5-90% of nylon 66, 1-35% of graphite powder, 0.3-1.5% of antioxidant, 0.1-3.0% of heat stabilizer, 0.1-2.8% of coupling reagent, 0.1-3.0% of HMW (high molecular weight) silicone oil and 0.3-5.5% of other auxiliaries. The self-lubricating abrasion-resistant injection-molding grade nylon 66 provided by the invention has the characteristics of environment friendliness and freeness from halogen; better self-lubrication and abrasion resistance are obtained on a basis of keeping the comprehensive properties of original filled nylon 66; meanwhile, a mold releasing operation is automatically carried out in the process of injection-molding or extruding finished products, so that a releasing agent is unnecessary; and the raw and auxiliary materials as well as production equipment are all domestic, so that the production cost and raw material cost are largely lowered, therefore the comprehensive competitive power of products is well improved.
Description
Technical field
The present invention relates to a kind of organic polymer composite, more particularly, relate to a kind of self-lubricating abrasion-resistant injection nylon 6 dragon 66 and manufacture craft thereof.
Background technology
Nylon 66 is to use at present one of maximum several engineering plastics, be widely used in the component of making various machineries, automobile, chemical industry, electronics and electrical means, his fusing point is higher, have good physical and mechanical property and wear resistance and self lubricity, be particularly suitable for high strength or wear-resisting product, these Comprehensive Characteristics are that other plastics are not available.But present society technology develop rapidly, make rapid progress, the product innovation new invention pours out, relate to requirement for picture and can effectively significantly reduce frictional coefficient, the stronger component of while starting material self wear resistance, the plurality of advantages of common nylon 66 allows the designer favor very much, but but above-mentioned shortcoming allows people's headache very much.The starting material with above-mentioned functions that provide in the market, or nylon 12 these classes are expensive, or add the additive material of the such costliness of tetrafluoroethylene, cause equally material cost high, like this, also require the relative starting material of starting material and production cost lower.Therefore, launched nylon 66 is carried out composite modified research.And Europe/Japan etc. developed country has started all restrictions of foreign imported product for various reasons at present, has set up a series of barrier, wherein to the material Halogen-free requirement of electric equipment products, is exactly one of them.Simultaneously, owing to containing many cyclophanes cyanogen in the more releasing agent, this also is the composition of strict restriction in present many environmental requirements, in order to ensure safety, the most direct way is exactly the easily demouldings of starting material itself, do not need to use releasing agent, the present technique invention produces in order to solve above-mentioned technical barrier.
Summary of the invention
The object of the invention is to effectively overcome the defective of prior art, self-lubricating abrasion-resistant injection-class graphite-filled nylon dragon 66 raw materials that a kind of environmental protection are provided and have good self lubricity and wear resistance.
Technical scheme provided by the invention is as follows: a kind of self-lubricating abrasion-resistant injection-class graphite-filled nylon dragon 66 of the present invention is made of nylon 66:49.5-90%, Graphite Powder 99: 1-35% by weight following composition; Antioxidant: 0.3-1.5%; Thermo-stabilizer: 0.1-3.0%; Coupling agent: 0.1-2.8%; High molecular silicone oil: 0.1-3.0%; Other auxiliary agents: 0.3-5.5%.
Self-lubricating abrasion-resistant injection-class graphite-filled nylon dragon of the present invention 66 Production Flow Charts are: first the graphite powder was placed 6 hours after mixing ten minutes under the 50 degree left and right sides conditions in proportion more naturally with coupling agent, in mixer, mixed 10 minutes with high molecular silicone oil after nylon 66 oven dry, then with antioxidant, thermo-stabilizer and other auxiliary agents proportionally after the weighing in mixer low speed mixing 10 minutes, vacuumize at the uniform velocity mixing extrusion through cord wood parallel equidirectional two-screw forcing machine in the screw combinations situation that medium tenacity is sheared again, the water cooling bracing pelletizing makes self-lubricating abrasion-resistant injection-class graphite-filled nylon dragon 66 materials through screening and dewatering.
The present invention has effectively overcome the defective of prior art, has the following advantages:
A kind of self-lubricating abrasion-resistant injection-class graphite-filled nylon dragon 66 of the present invention and manufacture craft thereof, environment friendly non-halogen, on the basis of the over-all properties that keeps original filled nylon-6 6, also possess preferably self lubricity and wear resistance are arranged, simultaneously in injection moulding or the voluntarily demoulding when extruding finished product, do not need to use releasing agent, raw and auxiliary material and production unit all adopt domestic, production cost and material cost reduce greatly, the good like this synthesized competitiveness that improves product.
Embodiment
Below be the most preferred embodiment of self-lubricating abrasion-resistant injection-class graphite-filled nylon dragon 66 raw materials of the present invention, therefore do not limit protection scope of the present invention.
Embodiment one, and a kind of self-lubricating abrasion-resistant injection-class graphite-filled nylon dragon 66 is provided, and is made of by weight nylon 66:69.4% following composition; High molecular silicone oil: 2.4%; The electrically conductive graphite powder: 25%, antioxidant: 1.0%; Thermo-stabilizer: 1.2%; Silane coupling agent: 0.5%; Other auxiliary agents: 0.5%;
First the electrically conductive graphite powder was placed 6 hours after mixing ten minutes under the 50 degree left and right sides conditions in proportion more naturally with silane coupling agent, the 85 degree oven dry of nylon 66 usefulness mixed in mixer 10 minutes with high molecular silicone oil after three hours, then with antioxidant, thermo-stabilizer, other auxiliary agents proportionally after the weighing in mixer low speed mixing 10 minutes, mixer adopts low speed mixing, paddle should with the barrel gap less than 0.5 centimetre, the supplementary material mixed effect should visual various particles and powder substantially even, do not have obvious agglomerate or gather; Twin screw extruder uses 40 length-to-diameter ratios, and medium tenacity is sheared, extracting vacuum, the screw rod slow speed of revolution that remains a constant speed; Adopt water cooling bracing pelletizing mode, namely make self-lubricating abrasion-resistant injection-class graphite-filled nylon dragon 66 materials through screening and dewatering.
