preparation example Construction

[0035] According to one embodiment, the preparation method may include: 50-100 parts by weight of at least one of homopolypropylene and copolymerized polypropylene, 0-50 parts by weight of inorganic filler, 15-25 parts by weight of 0.2-30 parts by weight of antioxidant, 0.5-20 parts by weight of toughening agent and 0.1-10 parts by weight of modified polymer are blended. This melt blending can be performed using known equipment such as a general mixer, a twin-screw extruder, a single-screw extruder, an open mill, an internal mixer, and the like. During the blending process, an appropriate amount of compatibilizer can be added as needed.

[0036] According to another embodiment, instead of the anti-ultraviolet auxiliary agent, the precursor of the anti-ultraviolet auxiliary agent can be blended with other components used to form the polypropylene composition, and then the precursor of the anti-ultraviolet auxiliary agent is blended under appropriate conditions (such as heating...

Abstract

The invention provides a polypropylene composition for a solar battery and a preparation method thereof, wherein the polypropylene composition for the solar battery comprises 50-100 parts by weight of at least one of homo-polymerized polypropylene and co-polymerized polypropylene, 0-50 parts by weight of inorganic filler, 15-25 parts by weight of anti-ultraviolet assistant, 0.2-30 parts of antioxidant, 0.5-20 parts by weight of plasticizer and 0.1-10 parts by weight of modified polymer. According to the invention, the polypropylene composition for the solar battery has good weather resistance, ultraviolet resistance and low-temperature impact resistance.

Description

technical field [0001] The invention relates to a solar cell device, in particular to a polypropylene composition for a solar cell and a preparation method thereof. Background technique [0002] With the frequent shortage of non-renewable energy such as coal and oil, energy issues have increasingly become a bottleneck restricting the development of the international society and economy. More and more countries have begun to implement the "Sunshine Plan" to develop solar energy resources and seek new impetus for economic development. In order to make solar cells get better applications, reduce the cost of solar cells, and improve the performance of solar cells has become the main task of related scientific research. At present, polyvinyl fluoride (PVF), polyethylene terephthalate (PET) and polyvinylidene fluoride (PVDF) films are mainly used in solar cell backplanes or insulating strips, and polyvinylidene fluoride (PVDF) films are mainly used in junction boxes. Phenyl ether...
