Description
Technical field
The invention belongs to field of high polymer material modification, and in particular to a kind of polypropylene blending modified material and its system
Preparation Method.
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 features such as method of PP blending toughenings industrializes small investment, rapid easy and notable effect with it and extensively should
With.Blending Toughening Modification refers to that elastomer or other plastics are blended as modifying agent and PP, improves PP toughness with this.Often
Modifying agent is broadly divided into plastics, rubber or elastomer and several major classes of inorganic rigid particle.
It is too late to reach toughness reinforcing purpose using plasticized modifier of the plastics as PP, and the wear-resisting of material can be made
Property, dyeability etc. are largely improved, and price is more cheap.There is high density polyethylene (HDPE) using more
(HDPE), LLDPE (ILDPE), ethylene-vinyl acetate copolymer (EVA), polyvinyl chloride (PVC), polyamide
(PA) etc..But it is due to their poor compatibilities with PP, system is reached higher toughness, generally requires to increase modifying agent
Consumption adds compatilizer.PP and PE are crystalline polymers, do not form eutectic between them, but each crystallization,
Form the bad heterogeneous system of compatibility.
The content of the invention
The present invention proposes a kind of polypropylene blending modified material, and this is material modified, and there is rigid toughening effect to have shock resistance again
Performance.
The technical proposal of the invention is realized in this way：
A kind of polypropylene blending modified material, according to the number of parts by weight, including following components：
80~90 parts of polypropylene, 10~20 parts of polyethylene, 5~10 parts of iso-cyanuric acid triallyl ester, bulking agent 20~
0.2~0.6 part of 26 parts, 1~3 part of coupling agent, 1~10 part of filler and antioxidant；Wherein, bulking agent is by ethylene-acrylic acid
Methyl esters-GMA terpolymer is constituted with polyacrylic acid.
Preferably, the quality of ethylene-methyl acrylate-glyceryl methacrylate terpolymer and polyacrylic acid
Than for 80~90:10~20.
Preferably, polyethylene is one kind or several in high density polyethylene (HDPE), low density polyethylene (LDPE), linear low density of polyethylene
The mixture planted.
Preferably, coupling agent is titanate coupling agent.
Preferably, filler is one kind or several in calcium carbonate, silica, kaolin, talcum powder, barium sulfate, wollastonite
The mixture planted.
Preferably, antioxidant is phenolic antioxidant or phosphoric acid ester antioxidant.
, proportionally, will it is a further object to provide a kind of preparation method of polypropylene blending modified material
Cross-linking radiation is carried out after each component is well mixed, is placed into screw extruder, blending extrusion, blending temperature is 180 DEG C~
210 DEG C, that is, obtain product.
Cross-linking radiation method is referred to the refined equality of sieve 2016 and existed《Chinese Tissue Engineering Study》What magazines were delivered
The Radiation Crosslinking Method that entitled " present Research of ultra high molecular weight polyethylene crosslinking with radiation " is introduced.
Beneficial effects of the present invention：
1st, the present invention is improved between polypropylene and polyethylene using iso-cyanuric acid triallyl ester by cross-linking radiation
Compatibility, by ethylene-methyl acrylate-glyceryl methacrylate terpolymer and polyacrylic acid constitute it is mixed
On the premise of compound, being mutually bonded for incompatible thing is improved, the compatibility of blend is improved, and improves its mechanical property
Energy.
2nd, the present invention obtains polypropylene blending modified material using the method for PP and PE blending and modifyings.This is polypropene blended
Material modified surface gloss reduction, extinction effect are good, can be applied to the fields such as packaging, commodity and construction material.
