Abstract
The invention discloses a kind of preparation method of high-impact automobile bumper material.It is characterized in that the bumper material includes the component of following parts by weight：Polypropylene：90 98 parts, toughener：1 10 parts, inorganic filler：10 15 parts, nucleator：0.1 2 parts, antioxidant：0.3 1.5 parts, coupling agent：0.1 1 parts, 0.1 2 parts of lubricant, other auxiliary agents：12 parts.In the present invention, trans-polyisoprene or sarin resin are added in polypropylene as toughener, using microporous foam technology, can not only reduce the density of finished product, and its impact resistance can be improved.
Description
Technical field
The invention belongs to polymeric material field, and in particular to a kind of environmental protection, high-impact, light fretting map car insurance
Thick stick material and preparation method thereof.
Technical background
Bumper is installed on automobile front and back end, not only with decoration functions, more importantly absorb and relax foreign impacts power,
Protect vehicle body protection vehicle body and the safety device of occupant safety function.Many years ago, bumper be based on metal material, with
Longitudinal beam is riveted or welded together, and has one section of larger gap with vehicle body, it appears that very unsightly.But plastics and gold
Belong to that material is compared with light weight, performance is good, preparation technology is simple, impact resistance, corrosion-resistant, energy consumption is low, can be processed into U.S.
The advantages that seeing profile, wherein polypropylene modified material constantly adapts to the requirement of various bumper materials, progressively replaces
Other bumper materials, the bumper produced using polypropylene modified material have been accounted for 70%, have turned into material for vehicle bumper
Main flow.
The bumper material using polypropylene as matrix is both needed to add toughener to improve the toughness of material, impact strength at present
And shrinkage factor is reduced, publication number CN102558803A Chinese patent discloses a kind of automobile bumper material and its preparation side
Method, this method improve the impact strength of material as toughener using the common elastomer (POE) of ethylene-octene, reduce shaping and receive
Shrinkage.Publication number CN103102592A Chinese patent disclose a kind of modified polypropylene material for bumper and its
Preparation method, using styrene-butadiene-styrene as toughener in a kind of embodiment of this method, at 23 DEG C
Under notch impact strength up to 40KJ/m2.Simultaneously because continuous improvement of the people for environmental consciousness, material are meeting power
Light while learning performance, energy-conservation has been increasingly becoming industrial design and development trend.
The content of the invention
It is an object of the invention to provide a kind of preparation method of high-impact bumper, especially a kind of guarantor of fretting map
Dangerous thick stick, there is the features such as excellent shock resistance, ageing-resistant and light.
A kind of preparation method of high-impact bumper, it is characterised in that be made up of by weight following components：Poly- third
Alkene：90-98 parts, toughener：1-10 parts, inorganic filler：10-15 parts, nucleator：0.1-2 parts, antioxidant：0.3-1.5 parts,
Coupling agent：0.1-1 parts, lubricant 0.1-2 parts, other auxiliary agents：1-2 parts.
The toughener is one or both of trans-polyisoprene, sarin resin；The inorganic filler is carbon
One or more in sour calcium, talcum powder, kaolin, montmorillonite, mica, calcium sulfate crystal whiskers, glass fibre；The nucleator is
One or more in benzoic acid cadmium, bismuth salicylate, titanium oxalate；The antioxidant is antioxidant 1010, antioxidant 1076, antioxygen
One or more in agent 626, antioxidant 618, antioxidant 1035；The coupling agent is silane coupler (such as KH-550, KH-
560th, KH-570 etc.), aluminate coupling agent (such as SG-Al821, DL-411, ASA), titanate coupling agent (such as TMC-101,
TMC-105 etc.) in one or more；The lubricant is one kind in calcium stearate, zinc stearate, ethylene bis stearamide
It is or a variety of；Other auxiliary agents are ultraviolet-resistant absorbent benzophenone (UV-9) and toner etc..
Wherein, the polypropylene can be the polypropylene that plain polypropylene can also be high fondant-strength.
Wherein, this bumper is a kind of microporous foam bumper.
Wherein, preparation process includes：
1) raw material mixes：Polypropylene, trans-polyisoprene, sarin resin, inorganic filler, anti-is weighed by quality proportioning
Oxygen agent, coupling agent, lubricant and other auxiliary agents, put into mixer and 3-5 minutes are stirred by mixed at high speed；
2) raw material is kneaded：The raw material mixed is put into double screw extruder, is granulated after melting extrusion, afterwards grain
Material parks 24h in an oven；
3) it is injection moulded：The pellet being kneaded is put into injection, goes out bumper semi-finished product through melt injection, is injected
Machine temperature is 180-220 DEG C；
