Abstract
The invention discloses a kind of high-strength wearable injection-level nylon and preparation methods, are grouped by each group of following weight percent content:Nylon 8 9~94%, anti-wear agent 1~10%, reinforcing agent 0.1~0.5%, antioxidant 0.1~0.5%.Each component mixes 2 after five minutes in high-speed mixer, through double screw extruder reactive extrursion to obtain the final product.Compared with the auxiliary agents such as currently used addition PTFE, molybdenum disulfide improve the wear-resisting method of nylon, material of the present invention has higher mechanical performance, and coefficient of friction is substantially reduced, and density reduces；Meanwhile the performance of material of the present invention can compare favourably with MC nylon, be suitble to injection, hence it is evident that processing efficiency is improved, it is cost-effective.
Description
Technical field
The present invention relates to a kind of using nylon as the composite material and preparation method of matrix, specifically a kind of high-strength wearable
Injection-level nylon and preparation method, belong to field of material technology.
Background technology
There is highly polar amide groups in nylon main chain, the hydrogen bond between amide groups enhances intermolecular combination power, easily makes knot
Structure crystallizes, so high mechanical strength, has good oil resistant, wear-resisting property, be widely used in fretting wear field.But
The highly polar of nylon makes it have more serious stick-slip in friction process, thus friction stability is poor, at the same with PTFE,
POM is compared, and the coefficient of friction of nylon is bigger than normal, and as running at high speed, the wear-resistant material high with intensity requirement is used with limitation.
In order to further improve the wear-resisting property of nylon, current main approach is the solid wear resistants auxiliary agents such as addition PTFE, molybdenum disulfide,
Or performance is high, wear-resisting MC nylon.And these antiwear assistants are to be dispersed in resin with graininess in process
In, and additive amount is larger, reduces the intensity of nylon material, hence it is evident that improve the density of material, and the process of MC nylon
Complexity, efficiency is low, of high cost, therefore further improves the mechanical performance and wear-resisting property of injection-level nylon, to expanding nylon material
Expect that the application range in fretting wear field has great importance.
The content of the invention
The purpose of the present invention is to solve current nylon as wear-resistant material there are it is above-mentioned the defects of and deficiency, provide one
Kind intensity is high, small nylon material of coefficient of friction and preparation method thereof.
To achieve these goals, the present invention adopts the technical scheme that：
Using nylon as matrix, the polymeric lubricant different from polytetrafluoroethylene (PTFE) (PTFE) is antiwear assistant, during this law is bright
Increase reactive functionality in the macromolecule of main chain as response type reinforcing agent, by blending, twin-screw reactive extrursion obtains machinery
Performance is high, the small nylon material of coefficient of friction.
High-strength wearable injection-level nylon material of the present invention is made of nylon base resin, anti-wear agent, reinforcing agent, antioxidant,
The incorporation of each constituent is respectively:Nylon 8 9~94%, anti-wear agent 1~10%, reinforcing agent 0.1~0.5%, antioxidant 0.1
~0.5%.
Further, the nylon is PA66, PA6 or its mixture, and the relative viscosity of nylon is 2.0-3.2, preferably
For 2.4.Anti-wear agent is polysiloxane block copolymers.Reinforcing agent is alkene and the copolymer of maleic anhydride.Antioxidant is to be obstructed
One or more kinds of mixtures in phenolic antioxidant, phosphite ester kind antioxidant, compound nantokite.
Further, anti-wear agent is the organosiloxane of silicon Han Liang≤10% and the copolymer of polyolefin.
Further, reinforcing agent is the alternate copolymer of the ethylene maleic acid acid anhydride of maleic anhydride Han Liang≤70%.
To achieve these goals, another technical solution for taking of the present invention is：
A kind of preparation method of high-strength wearable injection-level nylon, includes the following steps：
(1) reinforcing agent and antioxidant by high speed mixer are kneaded uniformly, are then mixed object and nylon, anti-wear agent
It is kneaded together and uniformly obtains premix.
(2) melt blending in double screw extruder is sent into premix, in 250-280 DEG C of extruding pelletization, screw speed is
200-400rpm。
The present invention compared with prior art, has the advantage that and is essentially consisted in feature：
(1) present invention uses polysiloxane block copolymers as anti-wear agent, not only with the excellent profit certainly of polysiloxanes
Slip and non-stick, while have better compatibility with nylon, experiment proves, compared with PTFE, is total to using polysiloxane block
Polymers can more obviously reduce the coefficient of friction of nylon as the anti-wear agent of nylon, solve the stick slip problems of nylon.
(2) there is the maleic anhydride of high-content, and maleic anhydride is polymerizeing in the alternate copolymer of alkene and maleic anhydride
On the main chain of object, therefore it is easy to react in extrusion with the end amido of nylon, significantly improves the molecular weight of nylon, simultaneously
The collateralization degree of nylon is improved, so as to significantly improve the intensity of nylon and toughness.
(3) compared with tradition is modified, the mechanical performance of injection molding nylon is further improved by the above method, reduces friction
Coefficient, and the density of material reduces by 10%, plays the role of loss of weight, while injection molding nylon is replaced in fretting wear field
For MC nylon, it will be apparent that shaping efficiency is improved, it is cost-effective.
(4) preparation method is simply easy to operate, each to expect that section temperature cooperates, and saves the time and good product effect is made.
