Detailed Description
It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present invention will be described in detail with reference to examples.
As analyzed in the background art, the problems of hole site bubbles, hole site splinters and high cost exist in the laminating process of the dual-glass assembly in the prior art, and in order to solve the problems, the invention provides the dual-glass assembly, the packaging method thereof and the electronic component.
In an exemplary embodiment of the present application, there is provided a method of encapsulating a dual glass assembly, the method comprising: laminating and laying the front layer of glass, the front layer of packaging adhesive film, the battery unit, the rear layer of packaging adhesive film and the rear layer of glass to obtain a laminated assembly, wherein the rear layer of glass is provided with an opening, the battery piece of the battery unit collects current through a bus bar, and the bus bar penetrates through the opening to be electrically connected with the junction box; filling the remaining part of the opening with a packaging material; and laminating the laminated assembly to obtain the double-glass assembly.
Adopt packaging material to carry out the lamination to the lamination subassembly after filling the remaining part of the trompil on the back layer glass to reduce the back layer encapsulation glued membrane and need to the volume that the trompil flows at the lamination in-process, and then reduced the risk that the glued membrane around the trompil is thin partially, further reduced the risk of battery piece fragment. On the other hand, back layer encapsulation glued membrane also can attenuate some relatively to the cost is reduced, simultaneously, trompil and back layer encapsulation glued membrane's synergism on the back layer glass are filled to the encapsulating material makes the trompil filled more abundant, thereby has reduced the hole site bubble, and is visible, adopts above-mentioned method of this application not only can reduce hole site bubble and hole site lobe of a leaf risk, can also reduce cost.
If the filling volume of the packaging material to the volume of the remaining part of the opening is too small, although the risk of breaking the battery piece can be reduced to a certain extent, the thickness of the rear-layer packaging adhesive film is reduced too little, and the cost reduction effect is not obvious. Preferably, when the filling volume of the packaging material is 5% -100% of the volume of the remaining part of the opening, the packaging material can be effectively filled in the remaining part of the opening, the risk of breaking the battery piece is reduced, the thickness of the rear-layer packaging adhesive film is reduced as much as possible, and therefore the cost is reduced.
In one embodiment of the present application, the encapsulating material is filled into the openings in granular form or in gel form.
The back glass of the laminated assembly faces upwards, and for the opening on the back glass, the packaging material can be filled into the opening in a granular form under the action of gravity, and the packaging material in a colloidal form can be filled into the opening under the action of gravity and fluidity. In the specific operation, the form of the packaging material can be selected according to the actual situation so as to conveniently fill the packaging material into the open hole.
The diameter of the opening on the back layer glass is about 3-4 cm, and the particle volume of the encapsulation material in the granular form is preferably 10-6mm3~104mm3Therefore, the particle volume of the single-particle packaging material is ensured to be smaller than the thickness of the conventional rear layer glass, and the rear layer packaging adhesive film at the opening position is not broken in the process of laminating the laminated assemblyThe crack is beneficial to controlling the filling density of the granular packaging adhesive film in the remaining part of the open pore, and if the volume of the particles of the packaging material is larger, the larger the pores formed among the particles of the packaging material after the open pore is filled, the more adverse to realizing the one-hundred-percent filling of the volume of the remaining part of the open pore, so that the reduction of the thickness of the rear layer packaging adhesive film is limited, and the drift of the particles of the packaging material is easily caused due to the too small volume of the particles of the packaging material in the granular form, thereby polluting the environment.
In one embodiment of the present application, the complex viscosity of the sealing material in a gel form is 300 pas to 105Pa · s, preferably 5200 to 9.26 × 104Pa·s。
The complex viscosity range of the encapsulating material is obtained by testing with a rheometer under the conditions of 160 ℃ and 0.5% deformation and the shearing frequency of 1 rad/s.
The packing material in the form of gel fills the opening by virtue of its fluidity, for example, it can be filled into the opening by glue filling. If the viscosity of the packaging material in the colloidal form is too large, the flowability of the packaging material is too small, so that the packaging material in the colloidal form is not favorable for being filled into the open pores, and if the viscosity of the packaging material in the colloidal form is too small, the flowability of the packaging material is too large, so that the packaging material at the open pores is easy to diffuse from the open pores to the periphery in the laminating process, the packaging material filled into the open pores is reduced, the buffering of the pressure applied to the open pores is not favorable, and the risk of breaking the battery piece at the open pores is still easy to cause. The preferred encapsulating material of the above viscosity both makes it easy to fill the opening and ensures its cushioning effect against the pressure to which the opening is subjected.
In an embodiment of the present application, the encapsulant is a cross-linking encapsulant or a non-cross-linking encapsulant, and the cross-linking encapsulant includes: 100 parts by weight of a first matrix resin, 0.01-2 parts by weight of peroxide, 0.02-3 parts by weight of cross-linking aid and 0.02-3 parts by weight of a silane coupling agent; preferably, the first matrix resin is selected from a copolymer of ethylene and any one or more of vinyl acetate, propylene, butene, pentene, hexene or octene; preferably the peroxide is selected from the group consisting of isopropyl t-butylperoxycarbonate, 2, 5-dimethyl-2, 5- (di-t-butylperoxy) hexane, 2-ethylhexyl t-butylperoxycarbonate, 1-bis (t-butylperoxy) -3,3, 5-trimethylcyclohexane, 1-bis (t-amylperoxy) cyclohexane, 1-bis (t-butylperoxy) cyclohexane, 2-bis (t-butylperoxy) butane, t-amyl peroxy 2-ethylhexyl carbonate, 2, 5-dimethyl-2, 5-bis (benzoylperoxy) -hexane, t-amyl peroxy carbonate, and mixtures thereof, Any one or more of tert-butyl peroxy-3, 3, 5-trimethylhexanoate; preferred co-crosslinking agents are selected from the group consisting of triallylisocyanurate, triallylcyanurate, trimethylolpropane triacrylate, trimethylolpropane trimethacrylate, pentaerythritol triacrylate, tris (2-hydroxyethyl) isocyanurate triacrylate, ethoxylated trimethylolpropane triacrylate, propoxylated trimethylolpropane triacrylate, ethoxylated glycerol triacrylate, propoxylated glycerol triacrylate, pentaerythritol tetraacrylate, ethoxylated pentaerythritol tetraacrylate, trimethylolpropane tetraacrylate, ditrimethylolpropane tetramethacrylate, propoxylated pentaerythritol tetraacrylate, 2,4, 6-tris (2-propenyloxy) -1,3, 5-triazine, tricyclodecane dimethanol diacrylate, trimethylolpropane triacrylate, propoxylated pentaerythritol tetraacrylate, 2,4, 6-tris (2-propenyloxy) -1,3, 5-triazine, tricyclodecane dimethanol diacrylate, trimethylolpropane triacrylate, and mixtures thereof, Any one or more of propylene glycol diacrylate, ethoxylated bisphenol A dimethacrylate, 2-butyl-2-ethyl-1, 3-propanediol diacrylate, diethylene glycol dimethacrylate, triethylene glycol dimethacrylate and polyethylene glycol dimethacrylate; preferably, the silane coupling agent is selected from any one or more of vinyltriethoxysilane, vinyltrimethoxysilane, vinyltri-tert-butylhydroperoxide, vinyltriacetoxysilane, vinyltris (beta-methoxyethoxy) silane, gamma-aminopropyltriethoxysilane, gamma-methacryloxypropyltrimethoxysilane, gamma-glycidoxypropyltrimethylsilane and 3-aminopropyltrimethylsilane; the non-crosslinked encapsulating material preferably comprises a silane-grafted second base resin, the grafting ratio of the silane-grafted second base resin is preferably 0.01-10%, and preferably 0.5-5%, the second base resin is preferably selected from one or more of PE, PP, EVA and POE, and the silane is preferably selected from one or more of vinyltriethoxysilane, vinyltrimethoxysilane, vinyltributyl peroxide, vinyltriacetoxysilane, vinyltris (beta-methoxyethoxy) silane, gamma-aminopropyltriethoxysilane, gamma-methacryloxypropyltrimethoxysilane, gamma-glycidoxypropyltrimethylsilane and 3-aminopropyltrimethylsilane.
The preferable composition of the packaging material is kept consistent with that of the rear layer packaging adhesive film as much as possible, so that the integration of the opening packaging material and the layer packaging adhesive film in the laminating process is facilitated, and the problems of cell fragment and hole position bubbles of the battery piece at the opening position are solved better. Wherein, the cross-linking type packaging material and the non-cross-linking type packaging material can be made into the granular packaging material.
In one embodiment of the present application, the melt index of the first matrix resin and the melt index of the second matrix resin are each independently 1 to 50g/10min, preferably 5 to 30g/10 min.
The melt index of the first matrix resin (second matrix resin) is too small, the flowability of the packaging material is too poor, the melt index of the first matrix resin (second matrix resin) is too large, the flowability of the packaging material is too good, and the flowability of the packaging material is too poor and too good, so that the integration of the packaging material and a rear-layer packaging adhesive film is not facilitated, therefore, the first matrix resin (second matrix resin) within the above melt index range is preferred, and the problems of cell fragment at the opening position and hole position air bubbles are further facilitated to be reduced.
In one embodiment of the present application, the melting points of the first matrix resin and the second matrix resin are each independently between 40 ℃ and 150 ℃.
If the melting point of the first matrix resin (the second matrix resin) is too low, the dual-glass assembly is easy to creep in the outdoor use process; if the melting point of the first matrix resin (second matrix resin) is too high, the first matrix resin is not melted during lamination, and the cell sheet may be crushed after pressurization. In order to enable the encapsulated dual glass assembly to have the capability of resisting thermal creep, the melting point of the first matrix resin (the second matrix resin) is preferably controlled to be 40-150 ℃.
In another exemplary embodiment of the present application, a dual glass assembly is provided, which is obtained by the encapsulation method described above.
By adopting the packaging method, the risk of breaking the battery piece in the laminating process of the laminated assembly is reduced, and the cost is reduced, so that the double-glass assembly has high quality and low cost.
