Description
Technical Field
The invention belongs to the technical field of engineering plastics, and particularly relates to a high-modulus high-conductivity carbon fiber reinforced material, and a preparation method and application thereof.
Background
Polyphenylene Sulfide (PPS) materials are widely used in the fields of aerospace, rail transit, electronic appliances, and the like, because of their excellent self-flame retardance, heat resistance, excellent rigidity, fatigue resistance, and the like. PPS also has its obvious disadvantages. The PPS molecular chain has high rigidity, low intermolecular force and high fluidity in a molten state, so that the PPS molecular chain is easy to overflow a die in the injection molding and compression molding processes, and the subsequent production and processing are puzzled. Meanwhile, the PPS material has over high rigidity and insufficient toughness, and can not meet the design requirements in some special application fields.
The prior art often modifies PPS to achieve desirable properties. Fiber reinforcement is currently the more common modification means in PPS modification. Fibrous fillers, because of their very excellent mechanical properties and their fibrous morphology with high aspect ratio, tend to give excellent mechanical properties by mixing the fibrous filler with the matrix material, but PPS materials of higher strength and modulus, high conductivity, still cannot be obtained by fiber reinforcement alone.
Disclosure of Invention
The invention aims to provide a high-modulus high-conductivity carbon fiber reinforced material, and a preparation method and application thereof. The high-modulus high-conductivity carbon fiber reinforced material has lower resistance, can realize excellent conductivity, has good mechanical property, wear resistance and conductivity stability, and can effectively prolong the service life of the material while maintaining higher conductivity.
In order to achieve the above purpose, the present invention adopts the following technical scheme: the high-modulus high-conductivity carbon fiber reinforced material comprises the following components in parts by weight: 30-75 parts of PPS resin, 15-40 parts of chopped carbon fiber, 15-45 parts of nylon 66 resin, 1-5 parts of molybdenum disulfide, 1-5 parts of carbon nano tube, 1-5 parts of dispersing agent, 5-15 parts of compatilizer and 1-5 parts of additive.
Preferably, the high-modulus high-conductivity carbon fiber reinforced material comprises the following components in parts by weight: 40-50 parts of PPS resin, 30-35 parts of chopped carbon fiber, 25-30 parts of nylon 66 resin, 2-3 parts of molybdenum disulfide, 2-3 parts of carbon nano tube, 2-3 parts of dispersing agent, 8-10 parts of compatilizer and 2-3 parts of additive.
Preferably, the PPS resin has a linear structure, and the melt index under 5kg test conditions at 316 ℃ is 150-1800g/10min. Further preferably, the PPS resin has a melt index of 220 to 500g/10min at 316℃under 5kg test. Melt index test criteria are according to ISO1133-1:2011.
preferably, the chopped carbon fibers have a fiber length of 4-8mm. The chopped carbon fiber is obtained by performing surface sizing treatment on the surface of the chopped carbon fiber by one or more of a polyurethane type surface treating agent, an epoxy resin surface treating agent and a polyamide surface treating agent sizing agent, wherein the weight percentage of the surface-coated surface treating agent is 1-3wt%.
Preferably, the nylon 66 resin has a relative viscosity of 80-180ml/g. The relative viscosity test criteria were as follows: ISO307-2017.
Preferably, the high modulus and high conductivity carbon fiber reinforced material at least comprises one of the following (1) to (5):
(1) The carbon nano tube is one or more of single-wall carbon nano tube and multi-wall carbon nano tube;
(2) The granularity of the molybdenum disulfide is 15000-20000 meshes;
as a solid lubricant, the molybdenum disulfide can effectively reduce the friction coefficient of the surface of the material, but the research of the invention discovers that the molybdenum disulfide is compounded with carbon fibers, so that the friction coefficient of the surface of the material can be reduced, and the friction loss of the material can be greatly reduced. The carbon fiber can improve the surface hardness of the material in the friction process, reduce the initial friction loss, gradually graphitize along with the friction, form a graphite layer on the surface of the material to play a role of lubrication, but gradually fall off along with the continuous friction, and gradually damage the surface of the material. The existence of molybdenum disulfide can play a good lubricating role, the time of carbon fiber graphitization is delayed, and after graphitization, a graphite layer is less prone to falling off, so that the friction loss is reduced.
(3) The dispersing agent is a compound of montan fat and hyperbranched polyester; wherein, the mass ratio of the montan fat to the hyperbranched polyester is 1: (1-3).
(4) The compatilizer is one or more of maleic anhydride grafted polypropylene, maleic anhydride grafted ethylene-octene copolymer, maleic anhydride grafted ethylene-propylene-butadiene and maleic anhydride grafted acrylonitrile-butadiene-styrene copolymer;
(5) The additive is at least one of an antioxidant and a lubricant.
Preferably, the high modulus and high conductivity carbon fiber reinforced material at least comprises one of the following (1) and (2):
(1) The antioxidant is at least one of 2,4, 6-tri-tert-butylphenol, 2' -methylenebis (4-methyl-6-tert-butylphenol), pentaerythritol tetrakis [ beta- (3, 5-di-tert-butyl-4-hydroxyphenyl) propionate ] and tris (nonylphenyl) phosphite or tris (2, 4-di-tert-butylphenyl) phosphite;
(2) The lubricant is at least one of N, N' -ethylene bis-stearamide, stearic acid, calcium stearate, stearate and erucamide.
The preparation method of the high-modulus high-conductivity carbon fiber reinforced material comprises the following steps:
s1, uniformly mixing all components except PPS resin and chopped carbon fiber in a formula amount, and then extruding, cooling and granulating to obtain semi-finished plastic particles;
s2, uniformly mixing the semi-finished plastic particles obtained in the step S1 with the PPS resin with the formula amount, adding the chopped carbon fiber for mixing, extruding, cooling and granulating to obtain the high-modulus high-conductivity carbon fiber reinforced material.
Preferably, the temperature of the extrusion, cooling and granulating steps in the steps S1 and S2 is 160-260 ℃.
The application of the high-modulus high-conductivity carbon fiber reinforced material in the preparation of aerospace, rail transit and electronic and electric products.
The simple chopped carbon fiber conductive material is characterized in that the carbon fibers are fibrous in the material, the fiber orientation direction is consistent with the flow direction of the melt, so that the carbon fibers can form good conductive paths in the orientation direction and have good conductivity, but the carbon fibers cannot form perfect passing in the vertical orientation direction, so that the difference between the conductivity in the vertical orientation direction and the conductivity in the parallel direction is large, and the conductive material is disadvantageous in the practical use process. Although the carbon nanotubes have a longer length-diameter ratio, the carbon nanotubes have certain flexibility, can be wound and bent in a resin matrix, and cannot be oriented along with the flow direction of a melt, and the phenomenon can greatly reduce resistance differences in different directions. The invention effectively solves the problems of orientation effect and healing permeation effect of single chopped carbon fiber conductive material through the compounding action of the chopped carbon fiber, the carbon nano tube and the dispersing agent.
Compared with the prior art, the invention has the following beneficial effects:
(1) The invention selects chopped carbon fiber, carbon nano tube, molybdenum disulfide and dispersant to compound and modify PPS resin, so that the prepared material has excellent mechanical property and lower friction loss, and can realize excellent conductivity and higher resistance stability.
(2) According to the invention, PPS resin and nylon resin are selected as matrix resin, so that a PPS/PA alloy system with adjustable fluidity is obtained, materials with different fluidity can be specifically designed aiming at different working conditions, and phenomena of flash and lack of glue of the PPS resin material in the forming process are improved.
(3) The invention improves the processing technology, so that the components can be fully mixed, and various fillers can be fully dispersed in matrix resin, thereby further improving the mechanical property, conductive property, wear resistance and other properties of the prepared material.

TABLE 4 Performance test results
From the experimental data in table 4, it can be known that the high modulus and high conductivity carbon fiber reinforced material prepared by the embodiment of the invention has higher young's modulus, realizes better material rigidity, has smaller surface resistance, can have higher conductivity, higher conductivity stability and lower friction loss, wherein the young's modulus can be kept in the range of 14350-21650 MPa, the surface resistance parallel to the melt flow direction can be realized in the range of 250-852 Ω, the surface resistance perpendicular to the melt flow direction can be realized in the range of 316-1005 Ω, the conductivity stability can be realized in the range of 70.0-86.8%, and the friction loss can be realized in the range of 1.33-2.78%. Meanwhile, the invention can adjust the weight parts of PPS resin and nylon 66 resin according to actual needs to obtain materials with different fluidity.
From the experimental results of the examples and comparative example 1, it can be known that when the carbon nanotubes are replaced by the same amount of chopped carbon fibers, the prepared carbon fiber material has higher surface resistance, which respectively reaches 3525Ω and 7520Ω, and the conductivity stability reaches only 46.9%; in comparative examples 2 to 3, only a single chopped carbon fiber or carbon nanotube is added, and the mixture is compounded with molybdenum disulfide and a dispersing agent, so that the surface resistance and friction loss are both high, and the conductivity stability is reduced; the molybdenum disulfide is absent in the comparative example 4, and the prepared material has lower surface resistance, lower conductive stability and higher friction loss, wherein the reason for the lower surface resistance is probably because the carbon nano tube is added into the system, and the addition of the carbon nano tube can effectively reduce the surface resistance; the lack of the dispersant component in comparative example 5 resulted in a significant increase in frictional loss possessed by the material and poor conductive stability.
The above embodiments are merely illustrative of the principles of the present invention and its effectiveness, and are not intended to limit the invention. Modifications and variations may be made to the above-described embodiments by those skilled in the art without departing from the spirit and scope of the invention.
