Solution in reactor carries out heating pressurization fusion, is taken out after fusion reaction 2-4h；
S6：Slurries prepared by step S5 carry out copy paper, and slurries are scooped up and uniformly spread out on gauze, then to copying on gauze
Paper carries out extruding and removes moisture removal, and the copy paper after extrusion forming is put in drying in dryer and obtains corrugated paper Bear-grudge, standby；
S7：Extracting corn starch 6-8 parts, sodium hydroxide 2-4 parts, water 40-55 parts, the stirring reaction 10-25min at 65-80 DEG C；Instead
Water 190-230 parts, polyethyleneimine 2-4 parts, tannin 4-6 parts, borax 1-2 parts and cornstarch 64-72 are added after having answered
Part, temperature control is obtained into sizing agent in 30-40 DEG C of stirring fully reaction 2-4h；
S8：Added at 30-40 DEG C in obtained sizing agent into step S7 titanium dioxide 5-8 parts, silica 3-6 parts and
Sodium polyphosphate 0.5-1.5 parts, are uniformly mixing to obtain mixing application agent；
S9：Mixing application agent made from step S8 is uniformly applied to corrugated paper Bear-grudge surfaces made from step S6, then will applying glue
Corrugated paper Bear-grudge afterwards carries out the corrugated paper of drying antibacterial and mouldproof.
3. the preparation method of the corrugated paper of antibacterial and mouldproof as claimed in claim 2, it is characterised in that the system of the oyster shell powder
Preparation Method is：The sodium hydroxide solution that the concentration for taking the weight such as oyster shell addition is 20-30% soaks 6-7h, then takes out washing
4 times, then dry, 150-200 targeted fine powders are ground into afterwards, are put in muffle kiln and 3.5- is dried at a temperature of 370-420 DEG C
4h, produce oyster shell powder.
4. the preparation method of the corrugated paper of antibacterial and mouldproof as claimed in claim 2, it is characterised in that in step S5 in reactor
At 135-155 DEG C, pressure is controlled in 40-45Kpa for reaction temperature control.
5. the preparation method of the corrugated paper of antibacterial and mouldproof as claimed in claim 2, it is characterised in that the drying temperature in step S6
Degree control is at 90-100 DEG C.
6. the preparation method of the corrugated paper of antibacterial and mouldproof as claimed in claim 2, it is characterised in that the drying temperature in step S9
Degree control is at 65-80 DEG C.
