Description
Technical field
The invention belongs to technical field of polymer materials, and in particular to a kind of modified polypropene and preparation method thereof.
Background technology
Polypropylene (PP) is one of fastest-rising kind in general thermoplastic resin, is widely used in industrial each
Individual field.It is as the important source material of blow molded product, and abundance is cheap, good processability, using quite varied.But
It is because its black brittleness, dimensional stability particularly notch sensitivity are poor, using receiving certain limitation.
The polypropylene material of copolymer type have relatively low heat distortion temperature (100 DEG C), low transparency, low-luster, it is low just
Property, but having stronger impact strength, polyacrylic impact strength increases with the increase of ethylene contents.Polyacrylic dimension
Card softening temperature is 150 DEG C.Because crystallinity is higher, the surface rigidity of this material and anti-scratch characteristic are fine.Polypropylene is not
There are problems that ESC.Generally, using addition glass fibre, metallic addition or the method for thermoplastic rubber to polypropylene
It is modified.Polyacrylic turnover rate MFR scopes are 1~40.Low MFR polypropylene material impact property is preferably but extension is strong
Degree is relatively low.For identical MFR material, wanting for the strength ratio homopolymer type of copolymer type is high.It is polyacrylic to shrink due to crystallization
Rate is at a relatively high, and generally 1.8~2.5%.And the direction uniformity of shrinkage factor is more far better than materials such as PE-HD.Add
30% glass additive can make shrinkage factor drop to 0.7%.The polypropylene material of homopolymer type and copolymer type all has excellent
Good resistance to water soak, antiacid caustic corrosion, antilysis.However, it is to aromatic hydrocarbon (such as benzene) solvent, chlorinated hydrocabon (carbon tetrachloride)
Solvent etc. is without resistance.Polypropylene also still has inoxidizability at high temperature unlike polyethylene.
The content of the invention
The present invention proposes a kind of modified polypropene, and not only toughness reinforcing shock resistance is good for the modified polypropene, and with good
Heat resistance.
The technical proposal of the invention is realized in this way：
A kind of modified polypropene, according to the number of parts by weight, including following raw material：
40~60 parts of COPP, 10~20 parts of HOPP, 10~20 parts of low density polyethylene (LDPE), phenolic resin 5
4~8 parts of~10 parts, 2~6 parts of Compatibilizer PP-g-MAH, 5~10 parts of filler and antioxidant.
Preferably, the filler is the mixture of talcum powder, titanium dioxide and mica powder.
Preferably, the antioxidant is phenol antioxidant or phosphoric acid ester antioxidant.
It is a further object to provide a kind of preparation method of modified polypropene, original is first weighed by weight ratio
Material, then by each raw material weighed it is well mixed after add to cooling after double screw extruder, extrusion, drying, pelletizing and produce modification
Polypropylene, wherein processing technology are：One 160~180 DEG C of area's temperature, two 210~220 DEG C of area's temperature, three area's temperature 210~220
DEG C, four 200~220 DEG C of area's temperature, five 200~210 DEG C of area's temperature, 300~500 revs/min of engine speed.
Present invention carries out a step elaboration：
Compatilizer of the present invention uses Compatibilizer PP-g-MAH without using traditional compatilizer POE-g-MAH, because
Inventor has found that PP-g-MAH is more beneficial for the shock resistance of phenolic resin RPP and heat-resisting by many experiments
Performance.
In some embodiments of the invention, it is found that filler uses the mixture of talcum powder, titanium dioxide and mica powder, can be with
Give full play to the lubrication filling effect of talcum powder, simultaneously because mica powder has netted Rotating fields, be more beneficial for polypropylene with it is low
Interaction between density polyethylene modification and crystal.
Beneficial effects of the present invention：
The present invention, as modifying agent, using PP-g-MAH as compatilizer, is added wherein using LLDPE
Phenolic resin, improves the impact strength and fire resistance of modified polypropene.
