Dealcoholized photovoltaic module sealant and preparation method thereof

The invention discloses a dealcoholized photovoltaic module sealant and a preparation method thereof. The photovoltaic module sealant is added with self-made multifunctional telechelic oligosiloxane and a modified siloxane tackifier, the molecular structure of a cross-linking agent is in a telechelic shape, and the cross-linking agent can well react with a main polymer; due to a certain molecular length and a partially hydrophilic structure, the situation that a cross-linked structure is dense after surface drying, water cannot enter the cross-linked structure, and deep curing is difficult to achieve can be prevented, and due to a stable benzene ring structure, the degraded activation energy can be improved, and the bonding strength of the sealant in a severe environment can be maintained; the molecular structure contains the tackifier of a multi-functional-group multi-silicon-oxygen chain link, so that the compatibility of a main polymer and other components can be improved, the adhesion with various base ma
