Referring to fig. 1 to 3, a method for manufacturing a plate material in an embodiment of a first aspect of the present invention includes the following steps:
s10, stirring raw materials to form slurry, wherein the raw materials comprise magnesium sulfate solution, light-burned magnesium oxide, strip wood chips 20, wood chip fibers, a modification reinforcing agent, a high-efficiency water reducing agent and a foaming agent. In order to ensure the structural strength of the formed slurry, the volume or mass ratio of the magnesium sulfate solution, the light-burned magnesium oxide, the strip wood chips 20, the wood chip fibers, the modification reinforcing agent and the high-efficiency water reducing agent is 90:100:25:3:2.2: 0.5-1. Adding magnesium sulfate solution into a stirrer, then sequentially adding a modification reinforcing agent and a high-efficiency water reducing agent, stirring, then adding light-burned magnesium oxide powder, uniformly stirring, then adding the strip wood chips 20 and the wood chip fibers, and finally adding a foaming agent to ensure that all raw materials can be uniformly stirred and mixed, particularly the strip wood chips 20 and the wood chip fibers can be uniformly distributed in the slurry. In the embodiment, the following mixture ratio is adopted: 90 kg of light-burned magnesium oxide (85 powder), 100 kg of magnesium sulfate solution (Baume degree is 29-30 degrees), 25 kg of strip sawdust, 3 kg of fine sawdust fiber, 2.2 kg of modification reinforcing agent, 0.5-1 kg of high-efficiency water reducing agent and a proper amount of foaming agent. Optionally, the length of the strip-shaped wood chips 20 is 12-16 mm, that is, the strip-shaped wood chips 20 with the length ranging from 12-16 mm are selected, the length of each strip-shaped wood chip 20 is not necessarily equal, and the strip-shaped wood chips 20 with the length enhance the overall strength and nail-holding power of the formed plate 10.
S20, pouring the slurry into a hopper, wherein a feed opening of the hopper is a wide variable opening, and the width of the feed opening is not less than two thirds of the width of the plate 10. Pouring the slurry on the template through a feed opening of the hopper, rolling the slurry on the template through a round roller after the slurry flows onto the template, so that the slurry is basically level, and then scraping the slurry by using a hard adhesive tape to further level the top surface of the slurry on the template; and (3) rolling by adopting a needle roller to form a plurality of blind holes which are uniformly distributed on the top surface of the sizing agent on the template, and finally laying a spacing layer 13, wherein the spacing layer 13 is attached to the top surface of the sizing agent on the template to form a supporting surface. Optionally, the spacer layer 13 is a fiberglass cloth. When the spacing layer 13 is laid on the top surface of the sizing agent on the template, the spacing layer 13 closes the blind holes, so that the blind holes form closed air holes 12, and after the plate 10 is formed, the air holes 12 have more excellent absorption and reflection functions on sound waves, so that the plate 10 can achieve a good sound insulation effect.
In some embodiments, step S20 is repeated at least once to reduce the thickness of each layer of slurry during forming, so that the flatness of the slurry during forming is more controllable, and in addition, more than two layers of air holes 12 can be formed to improve the sound insulation effect. In the present embodiment, step S20 is repeated once.
And S30, pouring the slurry onto the formwork, specifically, pouring the slurry onto the uppermost spacing layer 13 through a discharge opening of the hopper, wherein the spacing layer 13 plays a supporting role. And after the slurry is basically leveled by rolling the slurry by the round roller, the slurry is scraped by a hard adhesive tape so as to further level the top surface of the slurry on the template. In this embodiment, the thickness of the bottom layer slurry and the thickness of the top layer slurry are both 7mm, and the thickness of the middle layer slurry can be changed to manufacture the board 10 with different thicknesses. Each layer of slurry forms a component layer 11 after formation.
And S40, curing the template and then demolding. Specifically, the template is placed into a first-stage curing room for first-stage curing and then is demoulded, and during first-stage curing, the temperature of the first-stage curing room is raised, so that the moisture in the slurry can be removed, and the humidity of the slurry is reduced. As can be understood, the first-stage curing room has the functions of automatic heating, automatic heat mixing and automatic moisture removal. And (5) demoulding the blank after 20 hours of curing in a primary curing room.
And performing secondary curing on the demolded blank plates, specifically, stacking the blank plates and placing the stacked blank plates in a secondary curing room, and placing a layer of parting bead between every three blank plates, so that free moisture is conveniently discharged in the curing process of the plate 10, and the humidity of the blank plates is further reduced. It can be understood that the secondary curing room also has the functions of automatic heating, automatic heat mixing and automatic moisture removal. And continuously maintaining the embryonic plate in a secondary maintenance room for 5 days until the humidity of the embryonic plate is 13-15 ℃.
After the second-stage curing, double-side thickness-fixed sanding is carried out on the blank board subjected to the second-stage curing on a sanding production line, the thickness of the sanded blank board is 18-19 mm, the thickness of the board 10 after the sanding is finished is controlled to be 16mm, and the positive error and the negative error are 0.2 mm.
The sheet material 10 in the second embodiment of the present invention is manufactured by the above-described sheet material manufacturing method.
The board 10 contains a large number of strip-shaped wood chips 20, the volume of the strip-shaped wood chips 20 can reach 65-70% of the total volume of the board 10, the strip-shaped wood chips 20 and the wood chip fibers can effectively improve the nail holding performance of the board 10 and the biting force on a screw, in addition, the weight of the board 10 is also reduced due to the addition of the foaming agent, the board 10 is 25-30% lighter than a common glass magnesium board, the weight of each cubic meter of the board 10 is 700-750 kilograms, and the production and construction are convenient. It is worth mentioning that the strip-shaped wood chips 20 can be produced by breaking recyclable waste wood products, and most of the components can be degraded in the natural environment after the board 10 is discarded, thereby having environmental protection benefits.
In addition, as the plate 10 is rolled by the needle roller to form the air holes 12, the air holes 12 are uniformly arranged in the plate 10, and the plate has good heat insulation and sound insulation effects; moreover, the air holes 12 are formed inside the plate 10, and the surface of the plate 10 is smooth and easy to decorate and clean.
