Definitions
- the invention relates to a film and a preparation method thereof, and a method and a component thereof for applying the film, in particular to a polyolefin film used in the field of packaging, a preparation method thereof and a packaging method and assembly using the film.
- the packaging process is widely used in the fields of semiconductor devices, crystalline silicon cells, light-emitting semiconductor LEDs, organic light-emitting semiconductor OLEDs, display screens, etc., wherein a film for packaging is used for blocking packaging and protecting the functions of the packaged body.
- Polyolefin is a commonly used material for packaging films. Among them, ethylene-vinyl acetate resin and polyolefin elastomer are the two most commonly used materials in existing polyolefin packaging materials.
- EVA resin can be used as a sole material, agricultural film and hot melt adhesive.
- EVA with a high VA (vinyl acetate) content has a low melting point, generally below 90 °C.
- the film as a hot melt adhesive is usually made into a glue stick or a film before use. Users purchase glue sticks or films and use them according to their own processes.
- the content of vinyl acetate (i.e., VA) in the EVA resin is between 25% and 33%, the transparency is high, the light transmittance is higher than 90%, and it is also very soft.
- This range of EVA resin is very suitable as a laminated film in double glazing or a packaging film in a solar module, which can buffer the impact of the glass, and can also protect the photovoltaic cell in the solar cell module which is very brittle on the back side of the glass.
- this VA range of EVA resin has a melting point of 60-80 ° C, and its softening point is far below room temperature. It can not maintain dimensional stability and its own strength for a long time at room temperature, and must be cross-linked before long-term use.
- a thermal crosslinker For the purpose of crosslinking, a thermal crosslinker must be added to the EVA film for this type of application, usually an organic peroxide such as dicumyl peroxide (DCP) or tert-butyl-2-ethylhexyl carbonate. Butyl ester (TBEC) and the like.
- DCP dicumyl peroxide
- TBEC Butyl ester
- the EVA film with the cross-linking agent is placed between the glass of the double-glazing or the upper and lower sides of the cell after the solar module glass, and is heated to 135 ° C or higher while vacuuming, so that the EVA resin melts and fills the glass or the cell.
- the gap between the peroxides and the peroxide decomposition leads to cross-linking of the EVA resin.
- the degree of crosslinking of the EVA resin can be between 75% and 95%.
- the EVA film becomes a thermosetting material by cross-linking, and it is elastic but no longer melts, and it can maintain shape and strength forever.
- the commonly used EVA film has no cross-linking degree before use, and its dimensional stability is not good, and it is easy to overflow from the edge of the glass during heating to contaminate the processing equipment.
- a colored EVA film and a transparent EVA film are used together at the same time, due to poor dimensional stability, the interface between the color film and the transparent film is often unclear and the appearance is affected.
- a polyolefin elastomer that is, a POE resin, specifically refers to a copolymer of ethylene and butene, pentene, hexene or octene. It was originally invented by Dow Chemical Company of the United States and has a relatively narrow molecular weight distribution and uniform shortness. Branched-chain elastomeric copolymer of ethylene and octene.
- the ethylene chain crystalline region in the polyolefin elastomer acts as a physical crosslinking point, long-chain butene, pentane
- the olefin, hexene or octene forms an amorphous rubber phase which has both the elasticity of the rubber and the thermoplastic properties of the plastic; it is compatible with polyolefins, especially polyethylene and polypropylene, and is not unsaturated.
- the key is good in weather resistance, and it is used in a large amount for processing modified polyolefins, such as automotive parts for modified polypropylene.
- Polyolefin elastomers have a low melting temperature, usually between 50 ° C and 70 ° C, so they are rarely used alone.
- Patented CN103289582A describes a polyolefin elastomer which is formed by adding an organic peroxide after silane grafting to form a film which, upon use, decomposes the peroxide by heating to initiate a crosslinking reaction to improve the heat resistance of the polyolefin elastomer. Since the melting point of the polyolefin elastomer is very low, even in the case of adding a high melting point polyethylene or a crosslinking agent, the melting point of the elastomer portion is still very low, and the elastomer melts rapidly during heating. Very inconvenient or due to the low melting point, the transportation and storage temperatures are demanding, which limits its use.
- the melting point is low.
- the heating temperature of the solar photovoltaic cell assembly lamination process is generally between 135 ° C and 150 ° C, which is much higher than the melting temperatures of both.
- the film is gradually melted in the lamination, which is incapable of maintaining dimensional stability during the process, and the size and shape of the film before and after lamination are greatly changed.
- the most obvious example is that two layers of film smaller than glass are spilled from the periphery of the glass after lamination; or when one of the two films is colored, the interface between the two layers of film is ambiguous after lamination. , mutual penetration.
- Radiation crosslinking is a technical means for initiating a crosslinking reaction between long chains of high molecular polymer polymers by various radiations.
- ionizing radiation refers to rays such as alpha (alpha), beta (beta), gamma (gamma), X, and neutrons, which can ionize the species directly or indirectly (ie, An atom or molecule acquires or loses electrons and becomes an ion
- non-ionizing radiation such as visible light, ultraviolet light, sound radiation, heat radiation
- the lack of a close bonding force between the polymer polymer molecular chain and the chain causes the overall material to be deformed or destroyed when subjected to external forces and ambient temperature, which limits its application.
- a chemical bond or the like is formed between the long chains of the polymer polymer to improve the physical properties and chemical properties of the polymer, and is a very effective means for modifying the polymer.
- the radiation crosslinks the polymer itself does not physically contact the radiation generating device, and the shape of the polymer does not change before and after the reaction, but a crosslinking reaction has occurred inside the polymer.
- the polymer can directly crosslink the product in the radiation, and a crosslinking assistant can be added to the polymer to promote the efficiency of radiation crosslinking.
- non-ionizing radiation such as ultraviolet light has weak penetrating ability, limited curing depth, and photo-initiator must be added for UV curing. Therefore, partial cross-linking operation for high molecular polymers Difficult or inoperable; however, using an irradiation energy source capable of directly inducing a cross-linking reaction of a high-molecular polymer, such as ⁇ -ray, ⁇ -ray, X-ray, etc., since a photoinitiator is not required, the operation is more convenient, and partial crosslinking is realized. The effect is better.
- Radiation cross-linking is currently used in the production of heat-shrinkable tubes. It uses the plastic after radiation to have a shape-remembering ability due to cross-linking.
- the expanded plastic tube is expanded at room temperature to make it under heat. The ability to retract to the original shape.
