Technical field
The invention belongs to technical field of polymer materials, be specifically related to a kind of wear-resisting fiber glass reinforced polypropylene mixture and preparation method thereof
Background technology
because the plastic material light weight is inexpensive, employed a lot of component all are made of plastic on the automobile at present.In the prior art; Two kinds of materials of glass fiber enhanced nylon engineering plastics that the component that some of automobile are had relatively high expectations to wear resistance all adopt polyoxymethylene perhaps to be added with tetrafluoroethylene are usually processed; But costing an arm and a leg of these two kinds of materials; Under the increasing situation of present automobile industry's cost pressure, market in urgent need is sought a high-abrasive material cheaply and is substituted polyoxymethylene and nylon.Polypropylene material is cheap, if can in the cost controlled range, improve the wear resistance of polypropylene material, and this wear-resisting polypropene is applied to make the automobile wear parts, for reducing the automobile making cost with of great advantage
Summary of the invention
technical problem to be solved by this invention is to overcome that the automobile wear parts uses polyoxymethylene or the too high problem of nylon engineering plastic manufacturing cost more in the prior art, and a kind of wear-resisting fiber glass reinforced polypropylene mixture with low cost is provided.
the present invention also will provide a kind of preparation method of above-mentioned wear-resisting fiber glass reinforced polypropylene mixture.
The 3rd purpose of the present invention is that above-mentioned wear-resisting fiber glass reinforced polypropylene mixture is applied to make on the automobile wear parts.
For solving above technical problem, the present invention takes following technical scheme:

Wherein, the number-average molecular weight of said tetrafluoroethylene is 10 4 ～10 6 Between.
preferably, said polyacrylic melt flow rate(MFR) is 0.01～100 g/10min, further, said Vestolen PP 7052 can be selected from the COPP of HOPP or ethene molar content≤10% or both mixtures.
preferably, said thermo-stabilizer is one or more the combination in phenols thermo-stabilizer, amine thermo-stabilizer, phosphorous acid ester type thermal stabilizing agent and the calixarene kind thermo-stabilizer.
preferably, said lubricant is one or more the combination in metallic soap series lubricant agent, Triple Pressed Stearic Acid complex ester series lubricant agent and the amides lubricant.
preferably, said interfacial compatibilizer is one or several the mixture in high-density polycthylene grafted maleic anhydride, grafted low density polyethylene maleic anhydride, linear low density polyethylene grafted maleic anhydride, ethylene propylene copolymer grafted maleic anhydride, POE grafted maleic anhydride and the polypropylene grafted maleic anhydride.
preferably, said short glass fiber is an alkali free glass fibre.
The concrete preparation process of above-mentioned wear-resisting fiber glass reinforced polypropylene mixture is following:
add screw extrusion press with Vestolen PP 7052, thermo-stabilizer, lubricant, interfacial compatibilizer, tetrafluoroethylene from the main spout that is arranged in screw extrusion press one end, carry out melt blending; Short glass fiber is added the screw extrusion press from the side spout of said main spout 1/3 ~ 2/3 screw extrusion press length of distance, and after other components were carried out melt blending, extruding pelletization obtained said polypropylene composite; The length-to-diameter ratio of said screw extrusion press is 35 ~ 56:1.
further, the processing temperature for preparing above-mentioned polypropylene composite is 170 ℃ ~ 240 ℃.
the present invention preparation and wear-resisting fiber glass reinforced polypropylene mixture be fit to very much be used for making the component of on the automobile wear resistance being had relatively high expectations.
Because the enforcement of above technical scheme, the present invention compared with prior art has following advantage:
the present invention is through adding the tetrafluoroethylene of short glass fiber and specified molecular weight in the processing formula of Vestolen PP 7052 system; Can guarantee under the situation that other mechanical properties of material do not descend and cost of manufacture is lower, effectively the wear resistance of RPP composite materials.Tensile strength>=the 60MPa of product of the present invention, modulus in flexure>=6000MPa, normal temperature (23 ℃) notched Izod impact strength>=10KJ/m 2 , heat-drawn wire (1.80MPa)>=140 ℃, frictional behaviour can reach the wear-resisting grade of A1 of the wear-resisting standard D45 1010 of Aeolus-Citron Automobile Company Ltd.
The preparation method of polypropylene composite of the present invention has simple to operate, the characteristics that material property guarantees easily.
