Abstract

The invention discloses an insulating back panel of a solar photovoltaic cell. The insulating back panel is characterized by being prepared from the following raw materials in part by weight: 7-11 parts of acrylate rubber and / or ethylene acrylate rubber, 0.07-0.09 part of accelerant, 0.10-0.20 part of vulcanizing agent, 0.10-0.20 part of stearic acid and 1-7 parts of white carbon black or fluorous rubber. The invention also discloses a method for preparing the insulating back panel of the solar photovoltaic cell. The invention has the advantages of the reasonable formula of the raw materials,high insulating and ageing-resistant properties and high intensity. The preparation method is simple and reasonable; and the prepared insulating back panel of the solar photovoltaic cell is formed byan integral extrusion moulding process so as to effectively guarantee the service life of a photovoltaic cell component. The insulating back panel material of the solar photovoltaic cell can also be used as an insulating layer of various electric appliances.

Description

technical field [0001] The invention relates to an insulating board, in particular to an insulating backboard of a solar photovoltaic cell; the invention also relates to a preparation method of the insulating backboard of a solar photovoltaic cell. Background technique [0002] The production material and method of the traditional solar photovoltaic cell insulation backsheet is to paste the prefabricated fluoropolymer film, especially polyvinyl fluoride (PVF) film, on the polyester (PEF) substrate, typically on both sides of PET. The fluoropolymer film is attached to form a "sandwich" structure. The disadvantage is that such a backboard is easy to come off after being used outdoors for a long time, and the method of adding an adhesive layer to solve this problem not only increases the production steps, but also greatly increases the production cost. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a solar photovo...
