s3: pouring a degradable polymer mixed with a composite-breaking composition containing discrete particles of a filler between a knitted fabric layer (7) and an EPE film (9) to form a second degradable polymer (8);
s4: pouring a degradable polymer mixed by a composite-breaking composition containing discrete particles of a filler between an EPE film (9) and a weaved cloth layer (11) to form a third degradable polymer (10);
s5: pouring the degradable polymer mixed by the composite-dissolving composition containing the discrete particles of the filler between the woven fabric layer (11) and the kraft paper coating layer (13) to form a fourth degradable polymer (12);
s6, pouring the degradable polymer mixed by the composite-breaking composition containing the discrete particles of the filler between the PE film (5) and the knitted fabric layer (7) to form a first degradable polymer (6);
s7, packaging and molding the dried and bonded PET film (1), the aluminum foil layer (3), the PE film (5), the knitted fabric layer (7), the EPE film (9), the knitted fabric layer (11) and the kraft paper film coating layer (13).
7. The preparation method of the heat-preservation disinfection antibacterial composite material as claimed in claim 6, wherein the preparation method comprises the following steps: the speed of the PET film (1) and the aluminum foil layer (3) passing through the drying tunnel is 60-100m/min, the length of the drying tunnel is 3-5m, the temperature in the drying tunnel is three sections, namely 50 ℃, 60 ℃ and 70 ℃, the speed of the aluminum foil layer (3) and the PE film (5) passing through the drying tunnel is 60-100m/min, and the time of putting the aluminum foil layer (3) and the PE film (5) into the drying room is 20-30 hours.
8. The preparation method of the heat-preservation disinfection antibacterial composite material as claimed in claim 6, wherein the preparation method comprises the following steps: the composite adhesive is prepared from glue, a curing agent and ethyl ester according to the weight ratio of 8-12: 1-3: 11-15 by weight percent.
