Become.
The preparation method of a kind of automobile external door handle processing modified plastic particles, comprises the following steps:
1) first corn straw is added in high mixer with bagasse mixture, polyethylene, polypropylene, filler and be blended, altogether
Mixed speed is 1200r/min, and the time is 40 minutes, and pressure is 1.74MPa；
2) to corn straw and the bagasse mixture after being blended, polyethylene, polypropylene, filler mixture in add even
Connection agent, dispersant, heat stabilizer, plasticizer, after mix homogeneously, join in double screw extruder, controls extrusion temperature 243
DEG C, melt processing moment of torsion 72N m, pelletize in comminutor.
The present invention first with undressed corn straw and bagasse by direct blending reinforced plastics, but reinforced effects
The best, and then consider corn straw and bagasse surface are carried out pretreatment: utilize potassium permanganate solution to corn straw with sweet
Bagasse carries out surface modification, reaches the purpose of reinforced plastics, but the plastic product of modification still suffers from tensile toughness and shock resistance
Property not enough problem.Then, the present invention is again through substantial amounts of experimentation, by by mass percentage by potassium permanganate
0.5%, maleic acid 4.5%, sodium lactate 3.8%, dimethyl siloxane 1.2%, Oleum Caryophylli 2%, remaining is deionized water preparation modification
Agent, is modified corn straw and bagasse processing, and modified corn straw and bagasse are to the mechanical property of plastics, warm
The performances such as performance, rheological property and water resistance all have the effect of greatly facilitating.Have studied again corn straw with bagasse not
Same proportioning, through the modified impact on plastics performance, result shows, the hot strength of the plastics of preparation is along with bagasse content
Increase in first increasing the trend reduced afterwards；When the mass ratio of corn straw Yu bagasse is 2.72:1, its hot strength
Reaching maximum 28.6MPa, its mobility under hot shearing effect now reaches optimal.
The invention has the beneficial effects as follows: automobile external door handle processing modified plastic particles prepared by the present invention, with poly-second
Alkene and polypropylene are primary raw material, are aided with several functions auxiliary agent and prepare, and the processing forming of this modified plastic particles is good, it add
The automobile external door handle that work is made has mechanical strength, wearability, weatherability, impact resistance and the coating of excellence, has aobvious
The economic benefit write and ecological benefits, its biological degradability is excellent, is burying in 100 days, and quality can reduce by 4.35%.
Detailed description of the invention
A kind of automobile external door handle processing modified plastic particles, is made up of following component: corn straw by weight
With bagasse mixture 15, polyethylene 56, polypropylene 40, filler 27.6, coupling agent 1, dispersant 1.2, heat stabilizer 1.3, increasing
Mould agent 1.1；Described filler is mixed by precipitated calcium carbonate, sodium bentonite, nano-attapulgite, Lotus Root Starch.
Further, described corn straw is pressed 2.72:1 mass ratio with bagasse mixture by corn straw and bagasse
Mixing, described corn straw with bagasse through pretreatment: corn straw is become powder, so with bagasse mixture mixed grinding
After add in modifying agent, at 68-70 DEG C with 300r/min rotating speed stir, after react 1 hour, filter, washing, drying, i.e.
Can；Described modifying agent is made up of following component by mass percentage: potassium permanganate 0.5%, maleic acid 4.5%, sodium lactate 3.8%,
Dimethyl siloxane 1.2%, Oleum Caryophylli 2%, remaining is deionized water.
Further, described filler is pressed the mixing of 20:3 mass ratio by precipitated calcium carbonate, nano-attapulgite.
Further, described coupling agent is aluminate coupling agent with modified amido silane coupler by 8:1 mass ratio system
Become.
Further, described heat stabilizer is that calcium stearate is mixed by 20:1 mass ratio with epoxy resin.
Further, described plasticizer is that epoxy soybean oil mixes system with olive oil by 12:1 mass ratio at 85 DEG C
Become.
The preparation method of a kind of automobile external door handle processing modified plastic particles, comprises the following steps:
1) first corn straw is added in high mixer with bagasse mixture, polyethylene, polypropylene, filler and be blended, altogether
Mixed speed is 1200r/min, and the time is 40 minutes, and pressure is 1.74MPa；
2) to corn straw and the bagasse mixture after being blended, polyethylene, polypropylene, filler mixture in add even
Connection agent, dispersant, heat stabilizer, plasticizer, after mix homogeneously, join in double screw extruder, controls extrusion temperature 243
DEG C, melt processing moment of torsion 72N m, pelletize in comminutor.
By Experimental comparison's difference corn straw and the impact on plastic tensile intensity of the bagasse proportioning:
| Corn straw: bagasse | 1:1 | 2:1 | 2.72:1 | 3:1 | 4:1 |
| Hot strength/MPa | 13.4 | 22.1 | 28.6 | 24.8 | 10.5 |
Table 1
As shown in Table 1, along with the increase of the addition of corn straw, plastic tensile intensity first raises and reduces afterwards, and follow-up jade
The increase of rice straw can cause the hot strength of plastics to strongly reduce, and works as corn straw: the mass ratio of bagasse is 2.72:1
Time, plastic tensile intensity reaches maximum.
