A kind of highstrenghtpiston
Technical field
The present invention relates to the plastics field, specifically, the present invention relates to a kind of highstrenghtpiston.
Background technology
The ABS(acrylonitrile-butadiene-styrene (ABS)) resin is important general synthetic resin, and main body is vinyl cyanide, divinyl and cinnamic blend or terpolymer, is a kind of tough and tensile and the thermoplastics of rigidity is arranged.Its purposes is very extensive, automotive industry is usually used in making automobile component such as dashboard, vehicle-body outer panel, inner trim panels, bearing circle, insulating board, door lock, collision bumper, vent-pipe etc., household electric appliances are usually used in making as refrigerator, televisor, washing machine, vacuum cleaner, food mixer, the housing of telephone set etc., be usually used in making as sanitary apparatus at architectural decoration, the swimming pool lining, tubing and pipe fitting etc. are in addition also for the manufacture of safety helmet, the motorcycle plate washer, heel, the snowfield sporting goods, toy, clock, casing of loudspeaker box, suitcase, button, daily necessities and nameplates such as minaudiere, advertising matters such as ornament.
Although ABS is widely used, because the characteristic of the molecular structure performance of ABS own, make ABS deficiency aspect intensity.
Summary of the invention
The object of the present invention is to provide a kind of highstrenghtpiston.
In order to realize purpose of the present invention, the invention provides a kind of highstrenghtpiston, comprise following components by part by weight:
Preferably, described interface coupling agent is one or more in γ-An Bingjisanyiyangjiguiwan (KH550), γ-glycidyl ether oxygen propyl trimethoxy silicane (KH560), γ-(methacryloxypropyl) propyl trimethoxy silicane (KH570), ABS grafting toxilic acid (ABS-g-MAH), styrene-maleic anhydride copolymer (SMA), polycthylene grafted maleic anhydride (LDPE-g-MAH), linear low density polyethylene grafted maleic anhydride (LLDPE-g-MAH), the Racemic glycidol ether type epoxy.
Preferably, described toughner is MBS (MBS), MBS, hydrogenated styrene/Butadiene) in the segmented copolymer (SEBS) one or more.
Preferably, described dispersed lubricant is one or more in glyceryl monostearate, Tristearoylglycerol, ethylene bis stearamide, the bimonthly osmanthus of ethylene acid amides, the two amine hydroxybenzenes of ethylene, lower molecular weight ionomer, ethylene-acrylic acid copolymer, the ethylene-vinyl acetate copolymer.
Highstrenghtpiston of the present invention has excellent intensity, can be widely used for automotive industry and be usually used in making daily necessities and advertising matters such as nameplate, ornament such as automobile component, household electric appliances, architectural decoration, safety helmet, motorcycle plate washer, heel, snowfield sporting goods, toy, clock, casing of loudspeaker box, suitcase, button, minaudiere.
Embodiment
Below the invention will be further described for the description by embodiment, but this is not to be limitation of the present invention, those skilled in the art are according to basic thought of the present invention, can make various modifications or improvement, but only otherwise break away from basic thought of the present invention, all within the scope of the present invention.
Embodiment 1
The ABS that take by weighing 600 grams are following dry 4 hours in 90 ℃, then with silicon-dioxide 80 grams, glass fibre 130 grams, γ-An Bingjisanyiyangjiguiwan 50 grams, MBS 50 grams and glyceryl monostearate 8 grams, in homogenizer, stirred 5 minutes with 1100 rev/mins, emit after treating evenly.To add length-to-diameter ratio (L/D) be in 40 the twin screw extruder mixing equal materials of spoon, the processing temperature of twin screw extruder: 180 ℃ of district's temperature, two district's temperature are 185 ℃, three district's temperature are 195 ℃, and four district's temperature are 210 ℃, and five district's temperature are 215 ℃, six district's temperature are 225 ℃, seven district's temperature are 235 ℃, and eight district's temperature are 240 ℃, and engine speed is 320 commentaries on classics/min; Through extruding back cooling check rod, air-dry pelletizing, namely prepare highstrenghtpiston of the present invention.
Embodiment 2
According to preparing the highstrenghtpiston with embodiment 1 identical mode, difference is not use silicon-dioxide.
Embodiment 3
According to preparing the highstrenghtpiston with embodiment 1 identical mode, difference is not use glass fibre.
Experimental example
Impact property is tested by the ISO180-93 requirement, tensile property by the ISO527-93 requirement test, condition is 50mm/min, bending property control ISO178-93 requires to test, condition is 2mm/min, the result is as follows:
