Abstract
The invention relates to an organic polymer composite, in particular to special nylon-6 plastic for gears, which comprises, by weight, 6.45-85.5% of polyamide, 3.5-25% of cross-linking anti-wear agent, 5-30% of fibers, 0.1-2.5% of antioxidant, 0.3-2.4% of heat stabilizer, 0.3-5.5% of dioctyl-phthalate and 0.5-5.5% of activated carbon. The injection molding level self-lubricating special polyamide6 plastic for gears is low in noise and resistant to abrasion and especially applicable to gear production. Gears made from the special nylon-6 plastic have the characteristics of capability of eliminating noise when used with metal gears and further have better self-lubricating performance and abrasion-proof performance and cannot generate scraps due to abrasion, thereby being longer in service life.
Description
Technical field
The present invention relates to a kind of organic polymer composite, more particularly, relate to a kind of gear special-purpose nylon 6 plastics.
Background technology
Plastics are also divided into wide usage plastics and engineering plastics, mainly are that the popularity of purposes defines, and like PE, PP low price, can be used on the machine of multiple different kenels and produce.Engineering plastics then price are expensive, but raw material stability and physics rerum natura are all good a lot, and generally speaking, it has rigidity and toughness two specific characters simultaneously.Nylon 6 is to use one of several kinds of maximum engineering plastics at present; His amide group has polarity; In his structure, has well-set hydrogen bond; Make that the fusing point of nylon 6 is higher, have good physical and mechanical property and wear resistance and self lubricity, these comprehensive characteristics are that other plastics are not available.But the water-absorbent of common nylon 6 is big, and shock strength is on the low side before the suction, and suction back rigidity declines to a great extent again, shortcoming such as size instability simultaneously, thus limited the application of nylon 6, and then dwindled downstream industry design engineer's selection leeway again.Therefore, launched nylon 6 is carried out composite modified research.
Nylon 6 of the present invention is primarily aimed in gear, and gear is applied in those big machineries in the factory mostly, and the gear of being produced on the market now can make a noise when work; Simultaneously; If the time is used of a specified duration, also can decrease owing to long friction can cause having between the gear lubricant effect of certain wearing and tearing while gear between gear and the gear will cause the machinery and equipment running in the factory dumb like this; That have even cause decommissioning; Even as more exchange device can cause product not to be completed, can be a very serious problem so also for factory brings no small pointing out to producing streamline.
Summary of the invention
In order to overcome up the defective of technology, the present invention provides a kind of can produce the gears of different sizes in a large number fast through injection molding way, and has gear special-purpose nylon 6 plastic raw materialss preferably.
Technical scheme provided by the invention is following: a kind of gear special-purpose nylon 6 plastics of the present invention, by following composition by weight forming nylon 6:45-85.5%, crosslinked anti-wear agent: 3.5-25%; Fiber: 5-30%, inhibitor: 0.1-2.5%; Thermo-stabilizer: 0.3-2.4%; DOP: 0.3-5.5%, gac: 05.-5.5%.
The gear special-purpose nylon 6 plastics-production flow processs of a kind of low-noise, self-lubricated wear-resisting injection molding of the present invention are: at first nylon 6 and DOP are reacted in organic liquid reflection medium; The conjugate solutions of preparation nylon 6 adds crosslinked anti-wear agent, fiber, inhibitor and stirring again in conjugate solutions, mixed 20 minutes; Form nylon 6 emulsions; The adding of these reagent can make it to have self-lubricating property and wear resisting property, and carry out removal of impurities with gac so that the chemical property of nylon 6 plastics and physicals change; In nylon 6 emulsions that form, add thermo-stabilizer after the removal of impurities; Make the median size of the dispersed phase drop of this nylon 6 maintain 5～100um, and solidify nylon 6 emulsions, obtain solid nylon 6; Then solid nylon 6 being placed temperature again is that 120 ℃ the independent temperature control of screw rod band is penetrated and carried out injection moulding in the injection moulding machine of chewing, and can obtain gear special-purpose nylon 6 plastics.
The advantage of nylon 6 special for low-noise, self-lubricated wear-resisting injection molding gear dragon 6 plastics of the present invention: nylon 6 of the present invention is specially adapted for the manufacturing of gear; And the gear of this material produce has with metal gear the characteristic that can effectively abate the noise when shared; Self lubricity and wear resistance are preferably arranged simultaneously; Can not consider to be worth doing, thereby can provide than the long life because of the wearing and tearing dry linting.
Embodiment
Below be the most preferred embodiment of gear special-purpose nylon 6 plastic raw materialss of the present invention, therefore do not limit protection scope of the present invention.
Embodiment one, provides a kind of nylon 6 special for low-noise, self-lubricated wear-resisting injection molding gear dragon 6 plastics, by following composition by weight forming nylon 6:70.5%, crosslinked anti-wear agent: 8.5%; Fiber: 12.5; Inhibitor: 0.8%; Thermo-stabilizer: 1.8%; DOP: 2.7%, gac: 3.2%.
At first nylon 6 and DOP are reacted in organic liquid reflection medium, the conjugate solutions of preparation nylon 6, the crosslinked anti-wear agent of adding, fiber, inhibitor also stir in conjugate solutions again; Mixed 20 minutes, and formed nylon 6 emulsions, and carry out removal of impurities with gac; In nylon 6 emulsions that form, add thermo-stabilizer after the removal of impurities; Make the median size of the dispersed phase drop of this nylon 6 maintain 5～100um, and solidify nylon 6 emulsions, obtain solid nylon 6; Then solid nylon 6 being placed temperature again is that 120 ℃ the independent temperature control of screw rod band is penetrated and carried out injection moulding in the injection moulding machine of chewing, and can obtain gear special-purpose nylon 6 plastics.
The above; Be merely embodiment of the present invention; But protection scope of the present invention is not limited thereto; Any those of ordinary skill in the art are in the technical scope that the present invention disclosed, and variation or the replacement that can expect without creative work all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
