Abstract
The invention discloses a reinforced toughened anti-aging PP/nano-calcium carbonate composite material, consisting of (weight parts) PP resin 100, composite coupling agent 2-30, long glass fibers 2-30, composite toughener 5-40, nano-fillers 5-40, composite antioxidants 0.2-2, and processing aids 0.5-5. This composite material not only retains the original fine performances of polypropylene resin, but also improves markedly the physical and mechanical properties, thermal aging properties by using nanomaterial/new antioxidant synthetic modification technology. This invention also discloses the preparation method for reinforced toughened anti-aging PP/nano-calcium carbonate composite material.
Description
Technical field:
Patent of the present invention belongs to the polymer composite field, relate to a kind of nano polypropylene resin composite materials and preparation method thereof, the present invention has increased the range of application of acrylic resin, have good economic benefit and social benefit, be specially enhancing toughening anti-aging polypropylene alkene/nano calcium carbonate composite material and preparation method thereof.
Background technology:
Acrylic resin (PP) is a kind of thermoplastic resin, it is a kind of crystal polymer thing of compound with regular structure, have good thermotolerance, electrical insulating property,, low, the raw material of erosion resistance, density is easy to get, over-all properties is good and be widely used, in general-purpose plastics, get the only inferior and PE of consumption, be to increase the fastest kind that gets in the general-purpose plastics, be widely used in fields such as automobile, electronics, toy, military project, household electrical appliance, machinery, chemical industry at present; Yet virgin pp material at low temperature poor toughness, intensity and hardness is lower, loss of properties on aging has limited acrylic resin and must apply, modern science and technology get many-sided, the very high over-all properties of demand for development macromolecular material tool, and single acrylic resin is difficult to satisfy these performance requriementss.Utilize existing macromolecular material to carry out blending and modifying and prepare these high performance materials, can not only overcome single polymers material shortcoming in one aspect, and for the exploitation of product innovation also be a kind of be simple and direct economic again approach.Because polypropylene molecule is nonpolar crystal type material, be difficult to compatiblely with polar polymer or inorganic enhancing packing material, therefore utilize a certain polymkeric substance or certain mineral filler that polypropylene is carried out difficulty of modification ratio.
Summary of the invention:
The deficiency of aspect of performances such as the plain polypropylene resin is big in intensity, toughness, molding shrinkage in order to overcome, loss of properties on aging, patent of the present invention is with brand-new enhancing, toughness reinforcing, anti-aging and nanometer composite technology, integrated use is in the acrylic resin modification, the application of particularly novel anti-aging system, material modified physical and mechanical properties and thermal-oxidative aging property are all significantly improved again, make this novel material all be better than existing plain polypropylene resin at every aspect of performance.
The objective of the invention is that deficiency at the acrylic resin aspect of performance provides that a kind of molding shrinkage is low, intensity big, good toughness, good weatherability, enhancing toughening anti-aging polypropylene alkene/nano calcium carbonate composite material that ageing-resistant performance is good.
Another object of the present invention provides the method that a kind of flow process is simple, continuous, production efficiency is high, constant product quality prepares above-mentioned polypropylene/nano calcium carbonate composite material.
Nano polypropylene modified resin complexes of the present invention is made up of PP resinoid 100 weight parts, composite coupler 2-30 weight part, roving glass fiber 2-30 weight part, composite toughing agent 5-40 weight part, nano-composite material 5-40 weight part, composite antioxidant 0.2-2 weight part, processing aid 0.5-5 weight part.
The PP resinoid is one or both the composition in Co-polypropylene, the homo-polypropylene; Composite coupler is for increasing the material of nano-calcium carbonate consistency between acrylic resin, as titanate coupling agent, aluminic acid ester cpds, silane coupling agent or several compositions; Roving glass fiber is the alkali-free roving glass fiber; Composite toughing agent is one or more the composition among EPDM, POE, SBS, EVA, the EPR; The composition of one or more that nanoparticle is a median size in the lime carbonate of 10-200nm, mica powder, kaolin; Non-N half Hinered phenols of composite antioxidant, monothioester class, stupid and triazole species are as UV-531, UV-326, UV-327, UV-328, UV-5411, UV-2908, UV-P, photostabilizer 770, UV-3346,1010,168,619,626,1076,7024,7072 etc. composition.
Embodiment:
The present invention strengthens the preparation method of toughening anti-aging polypropylene alkene/nano calcium carbonate composite material, and the first step roving glass fiber and nano-calcium carbonate add composite coupler to be handled; Roving glass fiber and nano-composite material 5-40 weight part, composite antioxidant 0.2-2 weight part, the processing aid 0.5-5 weight part of second step with PP resinoid 100 weight parts, after handling mixes through high-speed stirring; The 3rd step was sent into said mixture in the twin screw extruder through the feeder of delicate metering, under the conveying and shearing action of screw rod, fully fusion, compound, through head extrude, tie rod, cooling, pelletizing, packing at last.
