Description
Technical field
The present invention relates to technical field of polymer materials, more particularly, to a kind of high-toughness polypropylene material and its preparation side
Method.
Background technique
The spies such as polypropylene (PP) material has low density, excellent in mechanical performance, processing performance good and environmental protection is easily recycled
Point has become one of the most frequently used, most rapid plastics variety of development in general-purpose plastics at present.The glass transition of polypropylene material
Temperature is higher, and be those semi-crystalline materials, not high, initial contraction rate that there are low-temperature flexibilities and post-shrinkage ratio it is bigger than normal, rigidity not
The disadvantages of sufficient, generallys use addition inorganic particle and is filled modification to PP material, in the prior art to improve its material stiffness
And dimensional stability, but it is poor etc. special due to the particle characteristics of inorganic particle and with the dispersion associativity of organic PP material
Property, addition usually will increase the brittleness of polypropylene material, be affected to the toughness of polypropylene material.
Coumarone indene resin also known as tonka-bean tung oil tree rouge are thermoplastic resin, and resistance to acid and alkali, resistance to ag(e)ing, heat resistance are good, tool
There is excellent service performance, is applied in multiple fields.Since coumarone indene resin has excellent reinforcing effect, usually quilt
As reinforcing agent, tackifier, but the disadvantages of its existing simultaneously property is crisp, coumarone indene resin also easily aggregates into the lump for being difficult to crush i.e.
Agglomeration, but can be realized after coumarone indene resin and the good combination of polypropylene material realization more excellent compared with inorganic particle MODIFIED PP material
Good material stiffness and dimensional stability, and as the coumarone indene resin of organic thermoplastic to the toughness of polypropylene material
Influence toughness or low-temperature flexibility smaller or even that polypropylene material can be improved.
Summary of the invention
The purpose of the present invention is in view of the shortcomings of the prior art, providing a kind of polypropylene (PP) material modified with coumarone indene resin
Material, to obtain good toughness especially low-temperature flexibility and high rigidity and dimensional stability.
The present invention solves the technical solution that above-mentioned technical problem uses are as follows: a kind of high-toughness polypropylene material, by poly- third
Olefine resin, coumarone indene resin, ethylene-octene copolymer and LDPE resin composition, the acrylic resin, coumarone indene resin,
The weight part ratio of ethylene-octene copolymer and LDPE resin are as follows:
Acrylic resin 50 ~ 90%
Coumarone indene resin 5 ~ 15%
Ethylene-octene copolymer 5 ~ 15%
LDPE resin 5 ~ 15%.
Further, the acrylic resin is the hybrid resin for being copolymerized PP, homopolymerization PP, the weight of copolymerization PP, homopolymerization PP
Amount part is compared for 1:1 ~ 2.
Further, it at 75 ~ 135 DEG C is solid coumarone resin that the coumarone indene resin, which is softening point,.
A kind of preparation method of the high-toughness polypropylene material, comprising the following steps:
(1) by above-mentioned weight part ratio be on the waiting list including copolymerization PP, homopolymerization PP, coumarone indene resin, ethylene-octene copolymer and
The raw material of LDPE resin, and the raw material being on the waiting list is sufficiently mixed uniformly using high mixer, obtain even mixing；
(2) premix that step (1) obtains is placed in double screw extruder by double screw extruder melting shear-mixed, taken out
Grain obtains pellet；
(3) after the pellet that step (2) obtains being removed moisture removal using 80 DEG C of 2 h of conditions drying, it is poly- to obtain high tenacity of the invention
Propylene material.
Further, controlling the double screw extruder extrusion temperature is 190 ~ 210 DEG C, screw speed is 350 ~
400r/min, vacuum degree are -0.06 ~ -0.10MPa.
The ethylene-octene copolymer (POE) is good thermoplastic elastomer (TPE), can with its tenacity-increased profax (PP)
Obtain good resultant effect；When carrying out toughening to different PP blends due to POE, all it is easy to get to the lesser dispersed phase of partial size
With relatively narrow particle diameter distribution, partial size is smaller, and distribution is narrower, and blend impact property is better and blend can be in lower bullet
Brittle-ductile transition is presented when elastomer content, copolymerization PP can be used as a compatilizer and play compatible work to whole system in the present invention
With compatilizer and auxiliary toughener can be played the role of simultaneously in homopolymerization PP/POE co-mixing system, so that POE is in PP system
Middle dispersibility is more preferable, and then preferably realizes the functionality of POE；Since the present invention is without inorganic particles such as talcum powder, but with
Cost is relatively low, and the coumarone-indene resin of steady sources makes PP material obtain more excellent material stiffness and ruler as modified feedstock
Very little stability；PE, which is added, in the present invention on a small quantity in co-mixing system can reduce the content of toughener POE, and the addition of PE is played
The effect of auxiliary toughening, to improve rigidity, while can reduce cost, in conclusion the present invention be it is a kind of have it is good
The toughness especially comprehensive performances such as low-temperature flexibility and high rigidity and dimensional stability polypropylene material.
