Description
Technical Field
The invention belongs to the technical field of packaging adhesive films, and relates to a multifunctional packaging adhesive film and a preparation method thereof.
Background
The packaging material plays roles of bonding protection and the like in the assembly, more and more battery pieces are used in the photovoltaic assembly, the performances of various battery pieces are different, and the requirements on packaging adhesive films are different; for example, the P-type cell needs a glue film with high PID resistance; the heterojunction cell with the circular welding strip needs an adhesive film with a non-slip surface, and the CIGS cell is not sensitive to heat and needs low-temperature lamination. The requirement on the packaging adhesive film is higher and higher, and the single-layer adhesive film or single material is difficult to meet the packaging requirement. The demand for adhesive films with multilayer structures and adhesive films prepared by blending various materials is increasing. With the increase of the required service life, the requirement on the attenuation of the peeling force of the packaging adhesive film is higher and higher, and the peeling force of the packaging adhesive film after the damp-heat aging needs to be maintained at a very high value. In the prior art, in order to improve the stripping force of the packaging adhesive film, a silane coupling agent is added as a first silane, and then other silane compounds are introduced as a second silane, but the addition of a large amount of second silane can reduce the crosslinking speed.
At present, there are many materials that can be used as the packaging adhesive film, such as ethylene-vinyl acetate copolymer (EVA), ethylene- α -olefin copolymer (POE), ethylene-methyl methacrylate copolymer (EMMA), ethyl-methacrylate copolymer (EMA), ethylene-acrylic acid copolymer (EAA), polyvinyl butyral (PVB), ionomer, etc., and the performances of various materials are different; the POE has the functions of high water resistance and PID resistance; EVA has the advantages of high light transmittance, high crosslinking speed and the like; PVB has large cohesive force and is suitable for BIPV building and the like. However, POE also has certain disadvantages, and with the MBB multi-master-grid technology, POE surface friction coefficient is small, polarity is low, and it is easy to cause cell pieces to slide, because POE polarity is small, it is easy to precipitate the auxiliary agent, resulting in short storage life, and POE crosslinking speed is slower than ethylene-vinyl acetate copolymer (EVA), which affects production efficiency. Meanwhile, the price of POE is much higher than that of EVA, which causes pressure on the cost of photovoltaic power generation. The conventional POE adhesive film has small stripping force, and the stripping force of the POE adhesive film is weak after moisture, heat and aging resistance. The reliability of the conventional packaging material EVA adhesive film can be increased to a certain extent, but the reliability problem cannot be ignored for the high-efficiency novel battery and the conventional packaging material EVA adhesive film, and the more severe requirement is provided for the packaging material.
CN110079244A A solar cell packaging material and a glue film formed by the packaging material, wherein the packaging material comprises the following components: A)66 to 99.5 wt.% of an ethylene copolymer, B)0.5 to 0.6 wt.% of an organic peroxide, C)0.1 to 3 wt.% of an alkoxysilane oligomer, and D) optionally 0 to 30 wt.% of further auxiliaries; wherein the sum of the weight percentages of the components is 100 percent; and the alkoxysilane oligomer is an alkoxysilane homopolymer, copolymer or mixture thereof having an average molecular weight of 300-2000 g/mol. The packaging adhesive film has the advantages of obviously improved volume resistivity and long-term adhesion to glass and a back plate, but the PID resistance of the packaging adhesive film needs to be further improved. However, the addition of the alkoxysilane oligomer of the present invention may reduce the crosslinking speed.
In addition, in the prior art, the matrix (except the auxiliary agent) used for each layer of the multi-layer adhesive film is a single material. In the actual production process of the product, the yield is low, and leftover materials cannot be recycled.
Therefore, it is necessary to develop a multifunctional adhesive packaging film with excellent anti-peeling force attenuation performance and anti-PID performance and a method for preparing the same, so as to meet the requirements of the adhesive packaging films with different functions.
