Abstract
The invention relates to the technical field of new film materials, in particular to a composite high temperature resistant release film. Compared with the prior art, the composite high temperature resistant release film is prepared by adopting a multilayer coextrusion composite technique, selecting polymethylpentene as the outer layer and selecting polyamide 66 as the inner layer comprising the range of layer 2-5, and by using a graft modification method, adding the modified special adhesive resin to glue PMP and PA66 perfectly. The prepared composite film synthesizes and strengthens the advantages of PMP and PA66 and reduces the influence of the disadvantages of PMP and PA66, thus being a new functional material with high physical strength, good high temperature resistance, high air tightness, low surface tension, low water absorption, low forming shrinkage and the like, can be used for replacing fluoroplastic films, and can be widely used in the fields of FPC printed wiring board , LED packaging, composite material moulding and the like. The composite high temperature resistant release film can replace the fluoroplastic in the fields with reducing cost and without influence of performances, and is a special functional material with high cost performance.
Description
Technical field
The present invention relates to the film new material technology field, particularly a kind of possess the release multi-functional complex fire resistant mould release membrance of heatproof.
Background technology
In the printing of FPC circuit board, LED encapsulation and composite material forming fields such as (air blowing, mold pressing, vacuum), demand is a to possess high temperature resistant release functional film simultaneously, common mould release membrance (as polyolefin such as PE/PP) heatproof can't meet the demands, the PET film causes operation to go up inconvenience because of rigidity is too high, thereby a lot of fluoroplastics of costliness of selecting are finished release function.
Summary of the invention
For solving existing defective of film and problem in the prior art, provide a kind of release multi-functional complex fire resistant mould release membrance of heatproof that possesses.
The technical scheme that the present invention is adopted for its technical problem of solution is: complex fire resistant mould release membrance of the present invention is made up of polymethylpentene and polyamide 66, adopt resin-bonding between polymethylpentene and the polyamide 66, adopt two-layer, three layers and five layers of three kinds of structural design, polymethylpentene comprises extrusion type and general unmodified type, and polyamide 66 comprises extrusion type and general unmodified type.
The invention has the beneficial effects as follows: compared with prior art, complex fire resistant mould release membrance film of the present invention adopts multi-layer co-extruded complex technique, the outer polymethylpentene (PMP) of selecting, internal layer is selected polyamide 66 (PA66), comprise two layers to five layers scope, way by graft modification, add improved special adhesion resin, PMP and PA66 perfection is bonding, the composite membrane of output comprehensively strengthens both advantage performances, reduce the weak tendency Effect on Performance, it is a high physical strength that has, high temperature tolerance, the high-air-tightness low surface tension, low water absorption, the new type functional material of multinomial advantages such as low molding shrinkage, can replace the application of fluorine plastic film in some field, the printing of extensive use FPC circuit board, LED encapsulation and composite material forming (are blown, mold pressing, vacuum) field such as, the present invention all can replace fluoroplastics in above-mentioned field, reducing cost and any sacrifice in performance not, is a specific function material that possesses high performance-price ratio.
The specific embodiment
Complex fire resistant mould release membrance film of the present invention mainly is made up of polymethylpentene and polyamide 66, polymethylpentene PMP comprises extrusion type and general unmodified type, polyamide PA66 comprises extrusion type and general unmodified type, other do not describe these two kinds of materials in kind is not included in, extrusion type is meant and comprises that two kinds of blown film and curtain coatings, general unmodified type refer to the injection moulding general field.Polymethylpentene, the English PMP that is called for short, PMP is a kind of special polyolefine material, because of its extremely-low density (0.83g/cm3, be minimum in the known plastic), high-temperature resistant (180 ℃ of the temperature that works long hours, short time can be to 200 ℃), low surface tension (reaching 24mN/m), chemical resistance (being insoluble to common solvent such as ethanol, acetone, the concentrated sulfuric acid, ammoniacal liquor, NaOH) and well-known near fluoroplastics, can make mould release membrance (paper), sheath, chemical container etc.
Polyamide 66 is a kind of engineering plastics of extensive use, and the English PA66 that is called for short uses with a long history.It is in recent years an emerging industry that PA66 is applied to make film.PA66 film and other high-temperature resistant membranes (PTFE, PET etc.) contrast has high cost performance, is an emerging industry that possesses the applications well prospect.
Adopt resin-bonding between the polymethylpentene of complex fire resistant mould release membrance film of the present invention and the polyamide 66, the outer polymethylpentene (PMP) of selecting, internal layer is selected polyamide 66 (PA66), comprises two layers to five layers three embodiment such as scope.
In first embodiment, the complex fire resistant mould release membrance adopts double-layer structure, ground floor adopts polymethylpentene and binder resin compound, and the second layer adopts polyamide 66 (PA66), and polymethylpentene and binder resin compound and polyamide 66 (PA66) are bonded together.
In second embodiment, the complex fire resistant mould release membrance adopts three-decker, and ground floor adopts polymethylpentene (PMP), and the second layer adopts binder resin, adopts polyamide 66 (PA66) for the third time.
In the 3rd embodiment, the complex fire resistant mould release membrance adopts five-layer structure, and ground floor and layer 5 adopt polymethylpentene (PMP), the second layer and the 4th layer of employing binder resin, and the 3rd layer is adopted polyamide 66 (PA66).
Comprehensive the foregoing description, complex fire resistant mould release membrance film of the present invention is by the way of graft modification, add improved special adhesion resin, PMP and PA66 perfection is bonding, the composite membrane of output comprehensively strengthens both advantage performances, reduces the weak tendency Effect on Performance, is a new type functional material with multinomial advantages such as high physical strength, high temperature tolerance, high-air-tightness, low surface tension, low water absorption, low molding shrinkages.
, but should be understood that under the situation that does not break away from relevant protection domain defined by the claims that those skilled in the art can make change and/or revise according to embodiments of the invention describing the present invention property and nonrestrictive description.
