A wood-plastic flooring structure convenient and quick to install comprises a supporting body, wood-plastic flooring unit bodies and rotatable buckles. Multiple parallel protruding guide rails are arranged on the supporting body in the length direction of the supporting body. Multiple inserting connecting grooves adjacent to the corresponding guide rails are evenly formed in the direction of the guide rails. Guide grooves are formed in the bottoms of the wood-plastic flooring unit bodies in the length direction of the wood-plastic flooring unit bodies and matched with the guide rails on the supporting body. The spliced sides where the wood-plastic flooring unit bodies are spliced with one another are provided with grooves in the long edge direction of the wood-plastic flooring unit bodies. Each rotatable buckle is in a T shape and comprises a horizontal clamping board and a vertical clamping board. Each horizontal clamping board is clamped in the grooves of the corresponding two adjacent wood-plastic flooring unit bodies. The bottom of each vertical clamping board is clamped in the corresponding inserting connecting groove in the supporting body. By the adoption of the provided wood-plastic flooring structure, the structural form that the supporting body and the wood-plastic flooring unit bodies are combined is adopted, dampness can be effectively prevented, installation is convenient and quick, and in the installation process, the labor cost and later maintenance cost can be saved.

The invention provides a making method of a substrate with a support. The making method comprises the following steps: forming the substrate, wherein the substrate comprises an effective zone for forming a device and an edge zone positioned at the periphery of the effective zone; forming a support plate in a shape corresponding to that of the edge zone of the substrate, wherein the support plate comprises a binding face matched with the substrate; binding and fixing the binding face of the support plate with the edge zone of the substrate. The making method has the benefits that the support plate is bonded with the substrate, so that the support plate has a function of reinforcing the edge of the substrate, and accordingly, can prevent the substrate from warping to a certain extent; the support plate and the substrate are bonded with one another and do not need to be disassembled. Compared with the mode of disassembling the bracket in the prior art, the making method can reduce the possibility that the substrate is damaged and broken.

The invention discloses a special low-warpage composite material for a notebook computer and a preparation method thereof. The composite material is prepared from the following main raw materials of PC (Polycarbonate) resin, ABS (Acrylonitrile Butadiene Styrene) resin, a flexibilizer, a fire retardant, an assistant fire retardant, a compatilizer, a wrapage preventing agent, an antioxidant and a processing aid. The preparation method comprises the following steps of: (1) firstly, placing the PC resin at 110-130 DEG C for drying for 2-4h; (2) uniformly mixing the dried PC resin with the ABS resin, the flexibilizer, the fire retardant, the assistant fire retardant, the compatilizer, the wrapage preventing agent, the antioxidant and the processing aid; and (3) fusing and extruding the mixed raw materials in the step (2) to prill to obtain a low-warpage composite material. The invention provides the special low-warpage composite material for a notebook computer, which is not easy to warp or deform and improves the product molding rate and the installing rate, and the preparation method thereof.
