Description
Technical field
The present invention relates to feature masterbatch field, and in particular to a kind of functional agglomerate of raising polypropylene antistatic ability.
Background technology
Polypropylene（PP）It is a kind of thermoplastic resin by obtained in propylene polymerization, is a kind of nontoxic, odorless, tasteless milky white
Color high crystallinity polymer, with good flexural fatigue resistance, chemical stability.Polypropylene arc resistance is good, dielectric coefficient is high,
Breakdown voltage is high, can be used to make electrical apparatus insulation product or electrical accessorie etc..But as polyacrylic high-insulativity makes polypropylene
Antistatic behaviour it is poor, limit polypropylene further applying in terms of electricity.Chinese patent CN105111582A, patent name
A kind of anlistatig polypropylene material, discloses a kind of being added with using polythiophene or siloxanes as modified poly- the third of antistatic additive
Alkene material.But the polythiophene of powder or siloxanes directly add that dispersion effect is bad and easy conglomeration, so as to affect poly- third
The consistency of performance of alkene material, and the antistatic effect of the antistatic additive is general.
Master batch be by the modified chemical auxiliary agent uniform load of super quantity in vector resin obtained from granular aggregation.With
Directly add modified chemical auxiliary agent in product to compare：The dispersion effect of master batch makes well the performance of product uniform, the carrier of master batch
The compatibility of resin and product resin makes well the performance of the product of addition master batch lift effect more preferably, master batch using safety,
Complete function.
The content of the invention
Cause antistatic behaviour difference for the high-insulativity of polypropylene material and affect polyacrylic application, existing improvement gathers
The problem that the additive effect of the anlistatig powder of propylene is not added with, it is an object of the invention to provide one kind is added to polypropylene material
In functional agglomerate, hence it is evident that improve polypropylene material antistatic effect, while functional agglomerate uniformly divides in polythene material
Dissipate and ensure polypropylene material product propertiess uniformity.
The present invention provides following technical scheme：
A kind of functional agglomerate for improving polypropylene antistatic, is prepared from by the component of following weight portion：Vector resin 80～
100 parts, 15～20 parts of PA resin particles, 10～15 parts of active oxidation aluminium powder, 10～15 parts of clay, magnesium chloride 10～15 part, point
Powder is 0.5～0.7 part, coupling agent is 0.5～0.7 part, and wherein vector resin is acrylic resin.
The functional agglomerate of the present invention is good with the compatibility of polypropylene material as vector resin from acrylic resin, can make
Functional agglomerate is uniformly dispersed in polypropylene material, and contributing to enhanced feature master batch improves the anlistatig ability of polypropylene material.
PA resins are i.e. by the aliphatic polyamide resin of amido link-[NHCO]-couple together.PA resins and polypropylene crosslinking blending
Afterwards, the amido link in PA resins easily forms hydrogen bond between hydrone, realizes in acrylic resin surface or internal solid water
Effect, suppresses acrylic resin product to produce electrostatic because being excessively dried.Active oxidation aluminium powder is dispersed by functional agglomerate
Inside acrylic resin.The electrostatic charge that the excellent conductive performance of active oxidation aluminium powder can disperse polypropylene unnecessary in time.Together
When active oxidation aluminium powder, clay and magnesium chloride easily absorb water, especially under magnesium chloride wet condition absorb water deliquescence into six water crystallizations
Magnesium chloride, and decompose release water in drying or hot environment, so as to alleviate the degree of drying on acrylic resin surface, suppress
The generation of electrostatic.The surface of clay is presented the positive charge produced during certain elecrtonegativity can neutralize polypropylene in addition, keeps poly-
Propylene charge balance.So by the synergism of PA resins, active oxidation aluminium powder, clay and magnesium chloride, make addition functional
The polypropylene material of master batch has good antistatic property.Dispersant makes each component in functional agglomerate in acrylic resin
Dispersed, coupling agent is effectively improved active oxidation aluminium powder, the surface activity between clay, magnesium chloride and polypropylene material, carries
The performance of high polypropylene material is uniform and stable.
Used as a modification of the present invention, the dispersant is barium stearate.Barium stearate belongs to metallic soap salt, can be equal
Each component in even divergent function master batch.Barium stearate transmits electric charge, synergistic activity aluminium oxide inside polypropylene material simultaneously
Powder disperses charge effect.
Used as a modification of the present invention, the coupling agent is chelating titanate coupling agent.Chelating type titanium esters coupling agent
With good hydrolytic stability, show good coupled in polypropylene material.

Min, the temperature range that each section of double screw extruder are 160～210 DEG C, Jing after fully melting and be combined extrude granulating；
（3）By step（2）Gained granule sieves through the screen cloth of -15 mesh of mesh～+20.
First raw material is stirred in mixing and blending machine high speed, the consistency of performance of functional agglomerate is improved.By double
Screw extruder melts compound extruded into graininess, improves dispersed degree of the functional agglomerate in polypropylene material, has
Help the performance uniformity of polypropylene material.The particle diameter of functional agglomerate can pass through the screen cloth of -15 mesh of mesh～+20, both ensure work(
Energy master batch is dispersed in polypropylene material, avoids the excessive impact functional agglomerate of particle diameter molten in polypropylene material preparation again
Melt dispersion effect.
As a modification of the present invention, step（2）The temperature control of each section of middle double screw extruder is respectively：One section
160～185 DEG C, 185～195 DEG C of two-stage nitration, three sections 195～200 DEG C, four sections 200～205 DEG C, five sections 205～210 DEG C,
Six sections 200～205 DEG C, die head temperature be 200～205 DEG C.By the operation temperature of each section of double screw extruder of setting gradually
Rise, each dispensing dispersion electric charge in abundant release function master batch, with reference to water and lubrication dispersing characteristic improves functional agglomerate performance equal
It is even consistent.
As a modification of the present invention, step is being carried out（3）By step before screening granule（2）Gained granule exists first
Aeration-drying 2～4 hours at 160～170 DEG C, obtain the granule of dry tack free.So can be equal with promotion functions master batch surface texture
It is even, also allow for the long-term storage of master batch.
Beneficial effects of the present invention are as follows：
