Description
Technical field
The present invention relates to a kind of preparation method of fluoroplastic film PP Pipe Compound, PP Pipe Compound is used in particular for producing and has excellent weather resistance, hangs down a kind of fluorine plastic film of water vapour permeability, mechanical property excellence.
Background technology
Pvdf (PVDF) is important a member in the Fluroplast-4 family, but because mobile poor, so melt-processed is difficult, film forming is more difficult.On the other hand; Pvdf has outstanding high-low temperature resistant, resistance to chemical attack and weathering resistance; Excellent electrical insulating property has been applied to industry, civilian many fields, and these premium propertiess of pvdf satisfy the requirement of solar cell package backboard film protection tunic just.One of technical problem that the present invention will solve is: develop the film PP Pipe Compound of pvdf, with preparation high-performance polyvinylidene difluoride film, satisfy the solar cell industry demand.
Solar cell backboard be by the fluoroplastic film with work-ing life more than 25 years or coating as resist, with as high pressure resistant, the excellent insulation performance of basic unit sheet material (as gather, be called for short PET) to the benzene tricarboxylic acid glycol ester be composited.Because need be to carrying out Chip Packaging, protection and the insulation that photovoltaic transforms; Make it can carry out photoelectricity for a long time, expeditiously and transform, therefore require backboard have higher electrical insulation capability, water-fast, at a distance from wet, anti-ultraviolet, acid and alkali-resistance and cold-resistant thermal shocking property.The fluorine plastic film layer is the most critical rete that shields in the backboard.
At present, solar cell backboard uses the fluorine membrane preparation technology to grasp for American-European few countries, and formation is cornered the market, so fluorine film price is very high, and like PVF (being called for short PVF) film, commodity are called Tedlar, du pont company production.There is the film of the terpolymer (being called for short THV) of tetrafluoroethylene, R 1216 and vinylidene fluoride in Minnesota Mining and Manufacturing Company.U.S. Honeywell company adopts trifluorochloroethylene (CF
2CFCl)-ethene (CH
2CH
2) multipolymer (being called for short ECTFE) preparation fluorine film.Akema company has prepared polyvinylidene difluoride film, and commodity are called Kynar, and vapor transmission property is not good but its film blocks water.Compare with PVF, PVDF is many fluorine atoms on molecular structure, so PVDF is finer and close, more weather-proof than PVF, water vapor barrier property is better, the water vapour permeability of pure PVDF film have only condition of equivalent thickness the PVF film about 1/5.And THV and ECTFE raw materials cost are higher, are inappropriate for large-scale promotion.But also there is the film forming difficulty in pure PVDF raw material; Buckling deformation easily after the film forming; The high deficiency of percent thermal shrinkage; Therefore press for pure PVDF raw material is carried out modification, develop the solar cell backboard of a kind of high tensile, high water vapor rejection property, high-weatherability, low heat shrinkage and use the polyvinylidene difluoride film PP Pipe Compound.
Summary of the invention
The present invention is intended to through pvdf is carried out blending and modifying, obtains a kind of solar cell backboard with high tensile, excellent weather resistance, low water vapour permeability, low heat shrinkage and uses the polyvinylidene difluoride film PP Pipe Compound.
The preparation method who the present invention relates to the polyvinylidene difluoride film PP Pipe Compound is following: (representing with weight part)
Pvdf 50～85 weight parts, enhancing resin 5～30 weight parts, mineral filler 5～15 weight parts, nano-sized filler 5～15 weight parts, mobile properties-correcting agent 0.5～5 weight part, thermally-stabilised auxiliary agent 0.1～2 weight part; Be added in the mixing and blending machine; The rotating speed that at room temperature changes with PM 50～1000 mixed 10～40 minutes; Then through twin screw extruder under 170～230 ℃, melt extrude, cool off, dry, pelletizing, obtain the PP Pipe Compound particle.
The used fluorine resin of the present invention is a kind of pvdf or several kinds of pvdf, and its index is a molecular weight, and molecular weight is between 20～1,000,000.
The used enhancing resin of the present invention is one or more in esters of acrylic acid or the methyl acrylic ester resin, and its index is a molecular weight, and molecular weight is between 5～200,000.
The used mineral filler of the present invention is one or more in silicon-dioxide, titanium oxide, lime carbonate, permanent white, the zinc sulphide, and its particle size is between 1～100 micron.
The used nano-sized filler of the present invention is one or more in nanometer grade silica, the nanometer grade calcium carbonate, and its particle size is between 1～100 nanometer.
The used mobile properties-correcting agent of the present invention is one or more in phthalate, the phosphoric acid ester, and its index is a boiling point, and its boiling point is not less than 170 ℃.
The used thermally-stabilised auxiliary agent of the present invention is one or more in Hinered phenols, phosphorous acid esters, the organic tin.
The polyvinylidene difluoride film PP Pipe Compound that the present invention relates to, flow ability modifying agent improves the flowability of Fluroplast-4 greatly, can melt extrude and film forming.Strengthen resin and play plasticising, toughening effect simultaneously, improve the tear strength of film greatly.Under the strong shearing action of twin screw extruder, Nano filling can homodisperse, and the introducing of nano particle helps reducing the sharp water vapour permeability of transmittance of film.This PP Pipe Compound of experimental result proof can realize the balance of all performances such as thin film mechanical performance, excellent weather resistance and low water vapour permeability, low heat shrinkage; It is a kind of solar cell backboard resist mould material of excellent performance; After the production domesticization, price is far below imported product simultaneously.
