Example Embodiment

[0043] The second aspect of the invention provides a method of preparing a crosslinked PoE film, wherein the method comprises the steps of:

[0044] (1) After mixing the cross-linked POE composition, the molten extrusion process is performed by a twin screw extruder to obtain a crosslinked PoE composition A;

[0045] (2) The cross-linking POE composition A is thermocically filled with film, and the cross-linking PoE film is obtained after cooling to room temperature;

[0046] Among them, the cross-linking PoE composition is the cross-linking PoE composition according to the present invention.

[0047] In accordance with the present invention, in step (1), the molten extrusion comprises: the extrusion temperature is 80-120 ° C, preferably from 30 to about 10 ° C; the rotational speed is 30-300 r / min, preferably from 100 to 200r / MIN.

[0048] In accordance with the present invention, in step (2), the hot press forming conditions comprise: the thermal pressure temperature is 150-...

Abstract

The invention relates to the field of cross-linked POE products, and discloses a cross-linkable POE composition and application thereof, a cross-linked POE film and a preparation method and application thereof. The crosslinkable POE composition comprises a POE polyolefin elastomer, a peroxide cross-linking agent, an assistant cross-linking agent, a nitroxide free radical inhibitor and an antioxidant, wherein relative to 100 parts by weight of the POE polyolefin elastomer, the dosage of the peroxide cross-linking agent is 0.05 to 2 parts by weight, the dosage of the assistant cross-linking agent is 0.05 to 2 parts by weight, the dosage of the nitroxide free radical inhibitor is 0.05 to 1 part by weight, and the dosage of the antioxidant is 0.05 to 1 part by weight. The crosslinked POE composition is not prone to early crosslinking in the processing process and has excellent processing stability in the extrusion/casting process of the composition, and the long-term stability of a crosslinked POE film prepared from the crosslinked POE composition under the conditions of high temperature, high humidity and high ultraviolet radiation can be remarkably improved.

Description

technical field [0001] The invention relates to cross-linked POE products, in particular to a cross-linkable POE composition and its application, a cross-linked POE film and its preparation method and application. Background technique [0002] POE has become an excellent solar encapsulation film due to its excellent optical properties, chemical resistance, etc. During the use of the solar encapsulation film, especially at noon in summer, the maximum temperature of the solar module can reach above 80°C. Therefore, in order to improve the thermal stability of the solar encapsulation film at high temperature, a peroxide cross-linking method is usually used to prepare a cross-linked film to improve performance such as high temperature resistance. In addition, due to the long-term operation of the solar encapsulation film outdoors, the encapsulation film needs to withstand outdoor high temperature, high humidity and ultraviolet radiation for a long time, and the yellowing index ...
