Description
Technical field
The present invention relates to a kind of gear, a kind of high abrasion ultra-toughness environmental-protection fire-resistant nylon gear is more particularly to.
Background technology
Nylon has a good combination property, including mechanical property, heat resistance, wear resistance, chemical proofing and from
Lubricity, and coefficient of friction is low, has certain anti-flammability, it is easy to process, because nylon has nontoxic, light weight, excellent machinery
Intensity, wearability and preferable corrosion resistance, therefore it is widely used in replacing the metals such as copper in machinery, chemical industry, instrument, automobile etc.
Bearing, gear, pump leaf and other parts are manufactured in industry.Molten polyamide has intensity very high after being spun into silk, mainly does and synthesizes
Fiber simultaneously can be used as medical suture
It is self-lubricating nylon truly, and fluid lubrication systems are formd in casting cycle so that oily nylon
Bearing service life is significantly improved, and reaches 25 times of 6 times of the bearing life of common nylon 6 and phosphor bronze bearing life！Oily nylon
The lubricant for including will not be lost in, adsorbs and exhaust, it is not required that add again.Lubricant has greatly widened Buddhist nun in oily nylon
The use scope of dragon, particularly to part that some can not lubricate.
But existing nylon gear uniquely relies on the limited anti-flammability of nylon itself, and the nylon gear one for improving
As mechanical strength it is not high, wearability is bad, and tensile strength is typically all in below 100MPa, therefore, it is necessary to provide a kind of resistance to
Grind the fire-retardant nylon gear of high-ductility.
The content of the invention
For the problem present on, the present invention provide it is a kind of with high abrasion, ultra-tough, epipodium environment friendly flame-retardant nylon tooth
Wheel.
The present invention realizes that the scheme of above-mentioned purpose is：A kind of high abrasion ultra-toughness environmental-protection fire-resistant nylon gear, the chassis
Composition includes：
In the present invention, SiO2 is added in polyamide as reinforcement, and SiO2 has stronger as inorganic material in itself
Anti-wear performance, is added in polyamide, can reinforcing material anti-wear performance, part energy can be absorbed when material is clashed into again
Amount, prevents the strand of polyamide material to be directly broken, and improves shock resistance, stretching and the fracture property of material.Resistance can be ensured
After combustion agent is added, the overall performance of material will not be reduced.The addition of technology chlorate can be with the hydrogen bond action in polyamide, master
If the addition of metal ion can reduce crystallinity, increase viscosity, with more preferable toughness, the presence of slaine makes in polyamide
Amorphous area formed be rigidly connected, greatly strengthen the mechanical property of polyamide.
Further, the polyamide is graft-polyamide.
Further, the grafted monomers of the graft-polyamide are polyolefin elastomer.
Polyolefin elastomer has more preferable compatibility with polyamide, is that polyamide is grafted with polyolefin elastomer
It is larger with intensity after grafting rate higher, and grafting, be conducive to the raising of the performance of final products.
Further, the fire retardant is triphenyl phosphate, TDE, antimony oxide, the compounding of montmorillonite
Thing.
Further, in the fire retardant by mass percentage：Triphenyl phosphate 15%~25%, TDE
35%~45%, antimony oxide 10~15%, balance of montmorillonite.
The decomposition temperature of polyamide is higher, typically all using aromatic fire retardant, but aromatic fire retardant meeting
In material surface Cheng Shuan, in the combustion process of polyamide, drip phenomenon is had, it is existing using drippage can be substantially reduced after montmorillonite
As TDE is used alone can also produce black smoke, the generation of black smoke can be greatly reduced after addition antimony oxide, right
During afterwards, first low-temperature burning when, triphenyl phosphate is decomposed, and the then decomposition of TDE reaches close in temperature
After 400 DEG C, antimony oxide part, montmorillonite have started fire retardation, therefore, the fire retardant of present invention compounding has broader temperature
Degree scope on probation, can play more preferable fire retardation, and due to being compounded using different materials, not only during fire-retardant
Black smoke, drip phenomenon will not be produced, and with limited oxygen index higher, fire resistance is more preferably.
Further, the metal chlorination salt is the mixture of lithium chloride and gallium chloride.
Further, the lithium chloride and the mol ratio of gallium chloride are 1:1.2~1.5.
Can be with the toughness of reinforcing material, if single use lithium chloride can be polyamide although lithium chloride is used alone
In the most of destruction of hydrogen bond, can substantially reduce the performance of material on the contrary, and use the proportioning that the present invention provides lithium chloride and
Gallium chloride lithium ion and potassium ion are acted synergistically, and can strengthen toughness, and the internal structure for not destroying polyamide is can guarantee that again, are caused
Performance reduction.
Further, the SiO2It is fibrous SiO2, SiO2Length be 200~300 μm, draw ratio be 50~80.
When material is impacted or is rubbed, if the length of SiO2 crosses conference with draw ratio to cause to be easy to fracture,
Extracted out in the base equivalent to SiO2, form larger defect, and if length and the smaller SiO2 that can cause monomer of major diameter
It is relatively thick, directly space can be formed in intrinsic silicon, the raising of material property is unfavorable on the contrary.
Beneficial effects of the present invention are：
(1) compound flame retardant, will not only produce black smoke, drip phenomenon during fire-retardant, and with pole higher
Limited oxygen index, fire resistance is more preferably；
(2) lithium chloride of rational proportion and gallium chloride lithium ion and potassium ion synergy, can strengthen toughness, and can protect
Card does not destroy the internal structure of polyamide, causes performance to reduce.
(3) SiO2 is added in polyamide as reinforcement, can reinforcing material anti-wear performance, can be subject in material again
Portion of energy is absorbed during shock, prevents the strand of polyamide material to be directly broken, improve shock resistance, stretching and the fracture of material
Performance.
