Preparation method of low-yellowing photovoltaic organic silicon adhesive

The invention discloses a preparation method of a low-yellowing photovoltaic organic silicon adhesive, and relates to the technical field of photovoltaic panel adhesives, in particular to a preparation method of a low-yellowing photovoltaic organic silicon adhesive which comprises the following components in parts by weight: 10-50% of a polydimethylsiloxane mixture, 40-55% of a nano light calcium carbonate filler, 5-10% of a curing agent, 1-5% of a curing agent, 1-5% of a curing agent, 1-5% of a curing agent, 1-5% of a curing agent and 1-5% of a curing agent. The adhesive comprises the following components in percentage by weight: 5-10% of viscosity modifier, 5-10% of light screening agent, 1.0-8% of cross-linking agent, 0.5-2% of coupling agent and 0.05-0.15% of mixed catalyst. According to the preparation method of the low-yellowing photovoltaic organic silicon adhesive, the nano light calcium carbonate filler, the activated heavy calcium carbonate and the titanium dioxide filler are added into a material t
