[0054] Target value of the coating amount of component A:

A double-sided adhesive double-coating compounding method with adjustable coating amount linkage according to claim 1, characterized in that: Perform a transfer coating test on B glue, and set a group of target values for the coating amount of B glue from 0.2 to 0.8 (g / m 2 ). Measure the rate η2 of the engraved gravure roll to the transfer coating roll corresponding to reaching the target value, and form a numerical corresponding table of the B glue coating amount value C B / the rate η2 of the engraved gravure roll to the transfer coating roll as the numerical source for subsequent retrieval or interpolation calculation; Coating amount value C of Adhesive B B / Experimental data of the rate η2 of the engraved gravure roll to the transfer coating roll: When the coating amount C of B glue B is 0.2 g / m 2 , the rate η2 of the engraved gravure roll to the transfer coating roll is η21; When the coating amount C of Adhesive B B is 0.3 g / m 2 , the rate η2 of the engraved gravure roll to the transfer coating roll is η22; When the coating amount C of B glue B is 0.4 g / m 2 , the rate η2 of the engraved gravure roll to the transfer coating roll is η23; When the coating amount C of Adhesive B B is 0.5 g / m 2 , the rate η2 of the engraved gravure roll to the transfer coating roll is η24; When the coating amount C of B glue B is 0.6 g / m 2 , the rate η2 of the engraved gravure roll to the transfer coating roll is η25; When the coating amount C of B glue B is 0.7 g / m 2 , the rate η2 of the engraved gravure roll to the transfer coating roll is η26; When the coating amount C of B glue B is 0.8 g / m 2 the rate η2 of the engraved gravure roll to the transfer coating roll is η27.
