Abstract
The invention discloses a kind of composite nucleating agent based on phenyl substitution hydrazides and include the polypropene composition of the composite nucleating agent.The composite nucleating agent is mainly to replace the compound of acyl hydrazine and its derivative and beta nucleater for phenyl, and compound ratio is：50:1~1:50.Including the composite nucleating agent composition based on parts by weight of raw materials including following component：100 parts of polypropylene, 0.001 10 parts of composite nucleating agent, 0.001 5 parts of antioxidant.The present invention is by adjusting composite nucleating agent each group distribution ratio so that polypropene composition has good heat resistance and lower temperature resistance, excellent mechanical property；And there is antioxidant, service life is long.There is good application prospect in polypropylene application field, is of great significance to the exploitation of high-performance polypropylene material.
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 phenyl
Core agent and polypropene composition.
Background technology
Polypropylene has low relative density, nontoxic, heat resistance, corrosion resistance, electrical insulating property as general thermoplastic resin
It is excellent, heat distortion temperature is high, easy processing and it is inexpensive the advantages that, have been widely used for numerous areas, and also constantly expanding
New application.But the shortcomings that its certain performance, also limits its application, for example its transparency is bad, intensity is undesirable etc..Needle
Disadvantage mentioned above is modified it, becomes the hot spot of Recent study.Polypropylene nucleater type is various, different types of
The function and effect of Nucleating Agent on Pp are different.Nucleating agent is broadly divided into α nucleating agents and beta nucleater at present, and α nucleating agents can improve
Polypropylene rigidity, but its toughness can be reduced, and beta nucleater can improve polypropylene toughness, can but reduce its rigidity, therefore, put down
Weighing apparatus modified polypropene rigidity becomes emphasis with toughness.The present invention provide it is a kind of based on phenyl replace hydrazides composite nucleating agent and
Its polypropene composition application scheme, reaches the balance of modified polypropene performance.

The present invention adopts the following technical scheme that.
Phenyl substitution acyl hydrazine and its derivative has the following structure：
R in formula1Indicate saturation that carbon atom number is 0-30 either unsaturated fatty chain, unsaturated alicyclic ring or aromatic ring；Preferably,
Phenyl replaces hydrazide compound nucleating agent to use two hydrazides of decanedioic acid diphenyl.
Beta nucleater includes：Fused ring compound nucleating agent, amides nucleating agent, dicarboxylate nucleating agent, terres rares nucleation
Agent.
Preferably, the beta nucleater is amides nucleant agent N, N '-dicyclohexyl -2,6- naphthalene diamides（NU-100）；
Dicarboxylate nucleating agent calcium pimelate (CaPi)；Terres rares nucleating agent WBG-2（Its structure is, x and 1-x are compoundsWithIon ratio；LIG1
It is the dicarboxylic acids and amides ligand that ligancy is m and n with LIG2）.
Preferably, two hydrazides of decanedioic acid diphenyl 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.
