Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a high-performance protective film on the back of a photovoltaic module containing a silane coupling agent and a preparation method thereof, which solves the problem that the existing protective film on the back of a photovoltaic module has a short service life, is easy to wear, and cannot be used during use. Better protection of photovoltaic modules, due to long-term sunshine and high temperature, will damage the structure of the protective film on the back of the photovoltaic module, and the existing back protective film will produce air pockets when used, which is inconvenient to use

Abstract

The invention discloses a high-performance protective film on the back of a photovoltaic module containing a silane coupling agent and a preparation method thereof. The raw materials of the protective film include: 85%-95% of natural rubber and 3%-5% of polyolefin plastomer resin by weight. %, ethylene-vinyl acetate copolymer 5%-8% and polyethylene 2%-5%, S1, first confirm whether the workshop environment, raw materials, raw material pots, melt mixing machines and high and low pressure film blowing machines are clean and free of residues , and whether personal hygiene and protective facilities are all qualified; the invention relates to the technical field of high-performance protective films. The high-performance protective film on the back of the photovoltaic module containing a silane coupling agent and its preparation method solve the problem that the existing protective film on the back of the photovoltaic module has a short service life, is easy to wear, and cannot better protect the photovoltaic module during use. Long-term sunshine and high temperature will damage the structure of the protective film on the back of the photovoltaic module, and the existing back protective film will produce air pockets when used, which is inconvenient to use.

Description

technical field [0001] The invention relates to the technical field of high-performance protective films, in particular to a high-performance protective film on the back of a photovoltaic module containing a silane coupling agent and a preparation method thereof. Background technique [0002] According to the application, the protective film can be divided into digital product protective film, car protective film, household protective film, food fresh-keeping protective film and so on. With the popularity of digital products such as mobile phones in China, protective film has gradually become a general term for screen protective films, and its functions in the field of screen protective films are also varied. The material has experienced more than 5 years of development from the earliest PP material to the current popular AR material, and has gradually been accepted by the majority of mobile phone groups. Functionally speaking, the protective film is to put a film on the ph...
