Description
Technical field
The invention belongs to polymer modification fields, more particularly to a kind of to replace being combined into for organic hydrazides based on alkyl
The polypropene composition of core agent.
Background technology
Polypropylene has many advantages, such as nontoxic, heat resistance, corrosion resistance, easy processing and inexpensive as general thermoplastic resin,
Numerous areas is had been widely used for, and is also constantly expanding new application.But the shortcomings that its certain performance, also limits
It is applied, for example its transparency is bad, intensity is undesirable etc..It is modified for disadvantage mentioned above, becomes and grinds in recent years
The hot spot studied carefully.Polypropylene nucleater type is various, and the function and effect of different types of Nucleating Agent on Pp are different.Nucleation at present
Agent is broadly divided into α nucleating agents and beta nucleater, and α nucleating agents can improve polypropylene rigidity, but can reduce its toughness, and beta nucleater
Polypropylene toughness can be improved, its rigidity can be but reduced, therefore, equilibrium modifiers polypropylene rigidity becomes emphasis with toughness.This hair
It is bright that a kind of composite nucleating agent and its polypropene composition application scheme being replaced hydrazides based on alkyl is provided, reach modified polypropene
The balance of performance.

LIG2 is the dicarboxylic acids and amides ligand that ligancy is m and n）.
Preferably, two hydrazides of decanedioic acid diethyl and NU-100, CaPi, WBG-2 are compound than being 1:1.
The present invention, which opens, discloses a kind of polypropene composition preparation method, it is characterised in that includes the following steps：According to the ratio, will
Polypropylene, composite nucleating agent, antioxidant are added in blender stir together, are uniformly mixed, then the addition of uniformly mixed material is double
It squeezes out, be granulated in screw extruder, polypropene composition is made；Double screw extruder barrel temperature is 180-240 DEG C, and screw rod turns
Fast 100-1000r/min.
Preferably, the composite nucleating agent of 0.001-10 parts by weight, 0.001-5 weights are mixed in the polypropylene of 100 parts by weight
Measure part antioxidant.
Preferably, the hybrid mode of polypropylene and composite nucleating agent, antioxidant uses common mechanical mixture.
In conclusion the present invention has the following advantages：The present invention is basic raw material with polypropylene, by the way that compound nucleation is added
Agent, antioxidant improve Mechanical Properties of PP；And there is antioxidant, service life is long.
