Description
Technical field
The present invention relates to a kind of organic polymer composites, are to be related to a kind of low friction high lubrication Buddhist nun more specifically
Imperial 66 material manufacture crafts.
Background technique
Nylon66 fiber is most one of several engineering plastics of current application, is widely used in the various machinery of production, automobile, change
The components of work, electronics and electric device, his fusing point is higher, has good physical and mechanical property and wearability and moistens certainly
Slip, particularly suitable for high-intensitive or wear-resisting product, these Comprehensive Characteristics are not available for other plastics.But present society skill
Art rapid development, makes rapid progress, and new product new invention pours out, for friction system can effectively be greatly reduced as being related to requirement
Number, while the stronger components of raw material itself wearability, the plurality of advantages of common nylon 66 allow designer to favor very much, but on
State disadvantage but very troublesome.Currently on the market provided by raw material or nylon 12 with the above function this
Class is expensive, or expensive additive material as addition polytetrafluoroethylene (PTFE), and it is high to also result in material cost,
In this way, the raw material and lower production costs that also require raw material opposite.Therefore, expand nylon66 fiber is carried out it is composite modified
Research.And developed country, Europe/Japan etc. has started for various reasons to the various limitations of foreign imported product at present, if
A series of barrier is found, wherein being exactly one of them to the material Halogen-free requirement of electric equipment products.Simultaneously as more
Containing polycyclic fragrant cyanogen in release agent, this is also the ingredient strictly limited in current many environmental requirements, in order to ensure safety, most directly
The method connect is exactly that raw material itself are easy demoulding, does not need to use release agent, this technology invention is exactly to solve above-mentioned skill
Art problem and generate.
Summary of the invention
It is an object of the invention to effectively overcome the defect of the prior art, provides a kind of environmentally protective and have excellent
Self-lubrication and wearability high 66 material of lubricated nylon of low friction.
Technical solution provided by the invention is as follows: a kind of high 66 material of lubricated nylon of low friction of the invention, is by following
Ingredient is by weight composition, nylon66 fiber: 85-95%, graphite powder: 3-15%；Antioxidant: 0.1-1.0%；Heat stabilizer:
0.1-1.0%；Coupling agent: 0.1-1.0%；High molecular weight silicone oil: 0.1-2.0%；Other auxiliary agents: 0.3-5.5%.
The high 66 material production procedure of lubricated nylon of low friction of the present invention is: first by graphite powder and coupling agent press than
Example mixes under the conditions of 50 degree or so places 6 hours naturally again ten minutes later, with high molecular weight silicone oil mixed after nylon66 fiber drying
It is mixed 10 minutes in material machine, after then proportionally being weighed with antioxidant, heat stabilizer and other auxiliary agents in batch mixer
Mixed on low speed 10 minutes, then taken out through building block system parallel equidirectional two-screw extruder in the screw combinations that moderate strength is sheared
High 66 material of lubricated nylon of low friction is made by screening and dewatering in vacuum at the uniform velocity mixing extrusion, water cooling bracing pelletizing.
The present invention effectively overcomes the defect of the prior art, has the advantage that
A kind of high 66 material manufacture craft of lubricated nylon of low friction of the invention, environment friendly non-halogen are keeping original filling Buddhist nun
On the basis of the comprehensive performance of dragon 66, it is also equipped with preferable self-lubrication and wearability, while being molded or squeezing out finished product
When can voluntarily demould, do not need to use release agent, raw and auxiliary material and production equipment be all made of it is domestic, production cost and raw material at
Originally it substantially reduces, improves the synthesized competitiveness of product well in this way.
Specific embodiment
It is the most preferred embodiment of high 66 material of lubricated nylon of low friction of the present invention below, does not therefore limit this hair
Bright protection scope.
Embodiment one provides a kind of high lubricated nylon 66 of low friction, is made of by weight following component, nylon66 fiber:
89%；High molecular weight silicone oil: 1.3%: electrically conductive graphite powder: 8.0%, antioxidant: 0.6%；Heat stabilizer: 0.4%；Silane
Coupling agent: 0.2%；Other auxiliary agents: 0.5%；
First electrically conductive graphite powder is mixed under the conditions of 50 degree or so in proportion with silane coupling agent natural again ten minutes later
Place 6 hours, nylon66 fiber mixes 10 minutes with high molecular weight silicone oil after drying three hours with 85 degree in batch mixer, then with resist
Oxidant, heat stabilizer, other auxiliary agents proportionally weigh after in batch mixer mixed on low speed 10 minutes, batch mixer use low speed
Mixing, paddle should be with barrel gaps less than 0.5 centimetre, and supplementary material mixed effect should visually various particles and powder be substantially equal
It is even, without obvious agglomerate or gather；Double screw extruder uses 40 draw ratios, and vacuum is extracted in moderate strength shearing, and screw rod is kept
The at the uniform velocity slow-speed of revolution；Using water cooling bracing pelletizing mode, high 66 material of lubricated nylon of low friction is obtained by screening and dewatering.
