Abstract: A method for manufacturing a biomass molded floor includes steps of: (1) preparing a PVC (polyvinyl chloride) board and a wood-plastic board, wherein a density of the wood-plastic board is in a range of 0.87-0.90 g/cm3; (2) coating an upper surface of the wood-plastic board with an adhesive, bonding the wood-plastic board with the PVC board, wherein an area of the wood-plastic board is in a range of 1000 mm×1200 mm-1000 mm×1800 mm; and (3) performing molding after bonding, wherein parameters of the molding are: temperature in a range of 35-40° C., pressure in a range of 10-12 MPa, time in a range of 50-60 s.

Abstract: A fireproof and waterproof biomass floor and a manufacturing method therefor. The floor comprises, in parts by weight, 80-95 parts of a wood fiber, 5-20 parts of an additive, and 0-1 part of a pigment. The additive comprises the following raw material components in percentage by weight: a metal oxide: 10-20 wt %; a hydrochloride: 10-20 wt %; a non-metal oxide: 5-10 wt %; a weak acid: 5-10 wt %; a sulfate: 1-2 wt %; a phosphate: 1-2 wt %; and water: 36-68 wt %. The manufacturing method comprises: mixing the wood fiber, the additive, and the pigment; flatly laying the obtained mixture on a base plate; performing die pressing, and standing for 3-10 days; performing demolding; subjecting the obtained demolded plate to edge cutting, drying, sanding, assembling, hot pressing, cutting, curing, slotting, and silent pad pasting on the back face. The floor has the advantages of being fireproof, ultralow in water absorption thickness expansion rate, and ultralow in formaldehyde release amount.

Abstract: A PVC rigid substrate, a preparation method therefor and a PVC rigid composite plate, wherein the PVC rigid substrate comprises the following raw materials in parts by weight: 40-50 parts of PVC, 75-150 parts of calcium carbonate, 0.6-1.0 parts of balance lubricant, 3.0-5.0 parts of stabilizer and 10-20 parts of CPVC. The PVC substrate has a high hardness, a very small heating size change rate which can be less than or equal to 0.05%. The impact resistance and toughness of a product may be greatly improved to facilitate the treatments that follow. Second, the PVC rigid composite plate has a high mechanical strength and a long service life; at the same time, the PVC rigid substrate can be prepared by using an extrusion method, which is very simple and easy to implement.
