[0012] Preferably, a first adhesive layer is provided on the bottom of the first fiberglass board, and a second adhesive layer is provided on the top of the second fiberglass board; an acid and alkali resistant layer is provided on the bottom of the second fiberglass board.

[0013] The present invention also provides a method for manufacturing a composite board suitable for outdoor use, characterized by comprising the following steps: placing a first fiberglass board and a second fiberglass board on the upper and lower sides of a PVC foam board respectively, pressing them with a hydraulic press to squeeze out the air bubbles in the middle, then trimming the first fiberglass board, the PVC foam board, and the second fiberglass board neatly, and sealing the edge strips on the outer side of the first fiberglass board, the outer side of the PVC foam board, and the outer side of the second fiberglass board using an edge sealing machine.

[0022] The preferred embodiments of the present invention are given below with reference to the accompanying drawings to illustrate the technical solution of the present invention in detail.

[0023] Example 1

[0024] like Figure 1 As shown, the composite board applicable to outdoor use in this invention includes a first fiberglass board 1, a PVC foam board 2, an edge banding strip 3, and a second fiberglass board 4. The PVC foam board 2 is located between the first fiberglass board 1 and the second fiberglass board 4, and the edge banding strip 3 is located on the outside of the first fiberglass board 1, the outside of the PVC foam board 2, and the outside of the second fiberglass board 4.

[0025] The present invention relates to a method for manufacturing outdoor composite panels, comprising the following steps: A first fiberglass board 1 and a second fiberglass board 4 are respectively placed on the upper and lower sides of a PVC foam board 2, and pressed using a hydraulic press to expel air bubbles from the center. The first fiberglass board 1, the PVC foam board 2, and the second fiberglass board 4 are then trimmed neatly. Edge sealing strips 3 are then sealed to the outer sides of the first fiberglass board 1, the PVC foam board 2, and the second fiberglass board 4 using an edge sealing machine. The pressure of the hydraulic press is controlled at approximately ten tons to prevent excessive pressure from deforming the composite panel, and insufficient pressure from preventing the air bubbles from being expelled.

[0026] The thickness of the first fiberglass board 1 and the second fiberglass board 4 are both 1mm to 2mm (preferably 1.5mm), and the thickness of the PVC foam board 2 is 11mm to 13mm (preferably 12mm). This way, the strength requirements are met with the least amount of material, resulting in low cost.

[0027] like Figure 2 As shown, the edge banding strip 3 has a U-shaped cross-section, which can cover the first fiberglass board 1, PVC foam board 2, and second fiberglass board 4, making it easy to assemble and disassemble, better fixing the first fiberglass board 1, PVC foam board 2, and second fiberglass board 4 together, and preventing water ingress.

[0028] The first fiberglass board 1, PVC foam board 2, edge banding strip 3, and the second fiberglass board 4 can be bonded together by injection molding, which can effectively prevent the three from separating.

[0029] The working principle of the composite board applicable to outdoor use in this invention is as follows: The first fiberglass board 1, PVC foam board 2, edge banding strip 3, and second fiberglass board 4 are all general standard parts or parts known to those skilled in the art. Their structure and principle can be obtained by those skilled in the art through technical manuals or conventional experimental methods. In use, the first fiberglass board 1 and the second fiberglass board 4 have strong weather resistance, operating between -196℃ and 300℃, and are sun-proof, making them suitable for outdoor use. The first fiberglass board 1 and the second fiberglass board 4 have strong chemical corrosion resistance, resisting strong acids, strong alkalis, aqua regia, and various organic solvents. They can withstand the effects of pharmaceuticals, rain, and snow, and are waterproof. The first fiberglass board 1 and the second fiberglass board 4 have high insulation performance, UV protection, and antistatic properties. They are not easily oxidized by ultraviolet light and have sun-proof properties, ensuring effective use. PVC foam board 2 uses polyvinyl chloride as the main raw material, with the addition of foaming agents, flame retardants, and anti-aging agents. It is extruded using specialized equipment to form a honeycomb mesh structure, resulting in a board with high strength and mechanical properties. Its elastic modulus can reach 1500-3000 MPa, making it less prone to deformation and preventing damage during transportation. The foam pores of PVC foam board 2 are closed, with a 95% sealing rate, preventing rainwater from seeping through and providing waterproofing.

[0030] Example 2

[0031] The structure of Example 2 is basically the same as that of Example 1, except that, as Figure 3 As shown, an elastic layer 5 is provided on the top of the first fiberglass board 1 to meet the elasticity requirements of the ping-pong ball, making the table surface less prone to damage and preventing noise when hit by the ping-pong ball.

[0032] The elastic layer 5 can be made of carbon fiber, which has the characteristics of high strength and high elasticity.

[0033] The elastic layer 5 can be made of natural rubber, artificial rubber, silicone, or plastic granules, and features low cost and high elasticity.

[0034] A waterproof paint layer 6 is provided on top of the elastic layer 5, which can be waterproofed and can be made into the desired color.

[0035] Example 3

[0036] The structure of Example 3 is basically the same as that of Example 1, except that, as Figure 4 and Figure 5As shown, a first adhesive layer 7 is provided on the bottom of the first fiberglass board 1, and a second adhesive layer 8 is provided on the top of the second fiberglass board 4. The adhesive layer can be glue or adhesive strip, which makes it convenient and firm to fix to the PVC foam board 2. An acid and alkali resistant layer 9 is provided on the bottom of the second fiberglass board 4. The acid and alkali resistant layer is made of epoxy resin modified acrylic resin, phenolic resin, acrylic resin and additives to prevent corrosion and improve service life.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics.
