Description

Composite board suitable for outdoor use and manufacturing method thereof Technical Field The invention relates to a composite board and a manufacturing method thereof, in particular to a composite board suitable for outdoor use and a manufacturing method thereof. Background At present, as introduced by patent No. 201821030306.1 and patent name "an outdoor SMC round table tennis table", patent No. 201520234109.1 and patent name "a novel table tennis table", patent No. 201220336966.9 and patent name "basketball stand for outdoor use", patent name 201820358807.6 and patent name "an SMC molded outdoor gas meter box", etc., the surfaces of these outdoor products are all made of SMC materials, the SMC materials are abbreviations of Sheet Molding Compound, that is, sheet molding compounds, the main raw materials are composed of GF (special yarn), UP (unsaturated resin), low shrinkage additives, MD (filler) and various auxiliary agents, and have excellent electrical insulation performance, mechanical properties, etc., but are difficult to manufacture, have low structural strength, are easy to deform, so that the transportation process is easy to damage, are not waterproof and sun-proof, are easy to be oxidized by ultraviolet, and cause poor use effect. Disclosure of Invention Aiming at the situation, the invention provides a composite board suitable for the outdoor and a manufacturing method thereof in order to overcome the defects of the prior art. The technical scheme is adopted to solve the technical problems, and the outdoor composite board is characterized by comprising a first glass fiber board, a PVC foam board, edge sealing strips and a second glass fiber board, wherein the PVC foam board is positioned between the first glass fiber board and the second glass fiber board, and the edge sealing strips are positioned on the outer sides of the first glass fiber board, the PVC foam board and the second glass fiber board. Preferably, the thickness of the first glass fiber board and the thickness of the second glass fiber board are 1mm to 2mm, and the thickness of the PVC foaming board is 11mm to 13mm. Preferably, the sectional shape of the edge banding is U-shaped. Preferably, the first glass fiber board, the PVC foam board, the edge banding and the second glass fiber board are bonded together in a hot melt mode through injection molding. Preferably, an elastic layer is provided on the first glass fiber board. Preferably, the elastic layer is made of carbon fiber.
