Fast development along with automotive industry, PP material is widely used as bumper, inside gadget, dashboard, body of vehicle light etc. because its over-all properties is more excellent, cost is lower, be easy to the advantages such as processing, but, how to overcome aforesaid defect, that acquisition has concurrently is high-strength, the PP of high-ductility performance, realizing toughness reinforcing enhancing simultaneously, is the large problem perplexing in the industry, is also the important development direction of PP material simultaneously.
Summary of the invention
For solving the deficiencies in the prior art, the object of the invention is to overcome the defect of prior art, provide a kind of and realize and strengthen toughness reinforcing PP material simultaneously, a kind of preparation method of this PP material is provided simultaneously.
In order to realize above-mentioned target, the present invention adopts following technical scheme:
A kind of PP of toughness reinforcing enhancing, it is characterized in that, comprise that the parts by weight of following component and each component are: 100 parts of polypropylene, EVA15-30 part, POE8-20 part, calcium carbonate 5-15 part, bismaleimides 3-10 part, lubricant 1-4 part, stablizer 1-3 part, antioxidant 3-6 part, fire retardant 0.5-2 part, tinting material 0-5 part.
Aforementioned calcium carbonate is nano-calcium carbonate, and median size is 20-100nm.
Aforementioned lubricants is a kind of in paraffin, Magnesium Stearate, polyethylene wax.
Aforementioned antioxidant is a kind of in antioxidant 1010, oxidation inhibitor PS802.
Aforementioned fire retardant is phosphorus flame retardant.
Aforementioned tinting material is a kind of in carbon black, red iron oxide, lemon yellow, titanium table basket.
In addition, the preparation method of a kind of toughness reinforcing enhancing PP, is characterized in that, comprises the steps:
S1, according to the weight ratio of toughness reinforcing enhancing PP claimed in claim 1, take each component, send into premixing machine, at 800-1500 rev/min of lower high-speed mixing 10-20 minute, obtain Preblend;
S2, by the Preblend feeding twin screw extruder of step S1 gained, body temperature is 160 ℃, district's temperature is 180 ℃, two district's temperature are 200 ℃, three district's temperature are 205 ℃, engine speed is 300 revs/min;
S3, extrusion moulding, cooling, through tablets press pelletizing, obtain the PP of toughness reinforcing enhancing.
Usefulness of the present invention is: enhancing Toughened PP of the present invention adopts polypropylene as matrix resin, EVA, POE and calcium carbonate are as main properties-correcting agent, not only solved the poor shortcoming of strength of PP, but also the impact strength of material is improved greatly, be applicable to the engineering plastic materials and parts of automotive field.
