fifthly, conveying the dried gypsum board to a cooling box to cool the gypsum board, wherein the cooling temperature of the cooling box is 15 ℃, conveying the cooled gypsum board out of the cooling box, conveying the cooled gypsum board into another film laminating machine after the cooled gypsum board is out of the cooling box, and bonding a buffer layer (5) on the outer side of a waterproof layer (4) in the film laminating machine;
and sixthly, the gypsum board with the buffer layer (5) bonded is packaged by packaging, and then the processing of the gypsum board can be completed.
2. The preparation method of the gypsum board with high compression resistance and high strength is characterized by comprising the following specific steps:
firstly, mixing the reinforcing strips (2) with gypsum slurry, uniformly spraying the slurry on a conveyor belt after mixing, discharging air bubbles in the slurry mixture through a vibration mechanism at the lower end of the conveyor belt, and scraping the surface of the gypsum slurry through a scraper;
secondly, primarily drying the gypsum slurry on the conveyor belt, and when the gypsum slurry is semi-dry, bonding the lower end of a film covering machine of the gypsum board through the conveyor belt, wherein when the gypsum board passes through the film covering machine, the waterproof layer (4) coated with the bonding layer (3) is bonded on the outer side of the gypsum board through the film covering machine;
thirdly, after the gypsum board is coated with the film, the gypsum board is cut off in equal length by a cutting device on the way of being transported to a dryer;
fourthly, the gypsum board is cut off and then enters a dryer, the interior of the dryer is dried, the drying temperature of the dryer is 200 ℃, the moisture remained in the gypsum board is dried in the dryer, and the bonding layer (3) can be dried, so that the bonding between the waterproof layer (4) and the base layer (1) is firmer;
fifthly, conveying the dried gypsum board to a cooling box to cool the gypsum board, wherein the cooling temperature of the cooling box is 15 ℃, conveying the cooled gypsum board out of the cooling box, conveying the cooled gypsum board into another film laminating machine after the cooled gypsum board is out of the cooling box, and bonding a buffer layer (5) on the outer side of a waterproof layer (4) in the film laminating machine;
and sixthly, the gypsum board with the buffer layer (5) bonded is packaged by packaging, and then the processing of the gypsum board can be completed.
