Description
Technical field
The present invention relates to field of plastics processing, specifically a kind of preparation method of fluoro-containing plastic processing aid and application.
Background technology
In the extrusion moulding process of TPO, when being blow molded into film as used containing LLDPE LLDPE raw material, there is critical shearing rate.When the shearing rate of Screw Extrusion is lower than critical shearing rate, the film surface of blowing is smooth, along with the shearing rate of Screw Extrusion higher than critical shearing rate time, phenomenon that film surface there will be " shark skin ", Here it is there is melt fracture.
When adding fluorine-containing polymer processing aids (PPA) and adding in TPO, in the process extruded, through the interface that the PPA of particular design can move to polymkeric substance and equipment, form the coating of a layered low-surface energy on the surface of equipment.This coating is the effect that the processing of polymkeric substance serves lubrication, and the shearing force that polyolefine is subject in the molten state significantly reduces, and eliminates " shark skin " phenomenon of film surface, solves melt fracture problem.
Summary of the invention
The object of this invention is to provide a kind of function fluoropolymer additive and preparation method thereof.
The present invention is to solve in the extrusion moulding process of existing TPO, the problem of phenomenon that film surface there will be " shark skin ".
A kind of fluoro-containing plastic processing aid of the present invention, each material component is by weight: fluoropolymer 20-60 part, interfacial agent 20-60 part, thermo-stabilizer 15-30 part.
Described vinylidene fluoride (VDF), tetrafluoroethylene (TFE), R 1216 (HFP), trifluorochloroethylene (CTFE), trifluoro-ethylene (VF3), at least one of perfluoro (alkyl vinyl) ethers or the combination of at least two kinds, in combination, each component ratio is selected arbitrarily.
Described interfacial agent is the combination of at least one in polyester polyol, amphipathic nature block polymer, functional group modification polyoxyethylene glycol or at least two kinds, and in combination, each component ratio is selected arbitrarily; Described amphipathic nature block polymer is poly glycol monomethyl ether or polymethylmethacrylate.
Described thermo-stabilizer is magnesium oxide, boron nitride, aluminium nitride, silicon nitride, silicon carbide, and at least one in ceramic microsphere or the combination of at least two kinds, in combination, each component ratio is selected arbitrarily.
The preparation method of fluoro-containing plastic processing aid of the present invention, the method is: by interfacial agent, thermo-stabilizer in proportion part add in reactor, equitemperature reaches 120-140 Celsius when spending, add fluoropolymer, insulated and stirred 30min, fully mix, discharging, pulverize i.e. obtained finished product with pulverizer.
The structure of this finished product auxiliary agent is that fluoropolymer is coated on the surface of thermo-stabilizer by interfacial agent; The median size of auxiliary agent is 800um ~ 1800um.
Advantage of the present invention: when fluorine-containing polymer processing aids (PPA) of the present invention is added after in TPO, in the process extruded, PPA can move to the interface of polymkeric substance and equipment, the coating of a layered low-surface energy is formed on the surface of equipment, this coating is the effect that the processing of polymkeric substance serves lubrication, the shearing force that polyolefine is subject in the molten state significantly reduces, eliminate " shark skin " phenomenon of film surface, solve melt fracture, reduce die orifice buildup, improve light and the slickness of product, improve simultaneously and extrude output, reduce melt pressure.
The thermo-stabilizer that the present invention uses is a kind of chemical structure of uniqueness.
