Abstract
The invention discloses a weather-resistant composite board, which takes a wood-plastic substrate as a base board, a weather-resistant layer is arranged outside the wood-plastic substrate, the wood-plastic substrate is sealed by the weather-resistant layer to prevent the wood-plastic substrate from contacting with the outside, thereby avoiding the aging of the wood-plastic substrate inside, improving the weather resistance of the composite board, preventing the weather-resistant layer from being influenced by the outside temperature, meanwhile, a steel structure layer is arranged outside the weather-resistant layer, the rigidity of the composite board is increased by the steel structure layer, a sealing layer is arranged outside the steel structure layer to further ensure the sealing property of the composite board and enhance the weather resistance of the composite board, a fireproof layer is arranged outside the sealing layer to effectively improve the fireproof property of the composite board and simultaneously effectively protect the sealing layer from being damaged, so that the weather-resistant structure of the composite board is not damaged, and the problem that the existing wood-plastic, poor weather resistance.
Description
Technical Field
The invention relates to the field of composite boards, in particular to a weather-resistant composite board.
Background
The composite board is a board formed by compounding a plurality of materials, and according to the difference of the materials, three types of composite boards are common at present: glass fiber reinforced plastic composite board, wood-plastic composite board and metal composite board. The above-mentioned composite materials are distinguished, but they all have more or less some drawbacks: compared with the prior wood-plastic composite board which has the advantages of poor high temperature resistance and aging resistance, complex processing technology, high cost and heavy material, the wood-plastic composite board has higher practicability, and the prior wood-plastic composite board is easy to be decomposed and deformed after long-term use and has poor weather resistance.
Disclosure of Invention
The invention mainly aims to provide a weather-resistant composite board, and aims to solve the problems that a wood-plastic composite board in the prior art is easy to decay and deform after being used for a long time and has poor weather resistance.
The technical scheme for solving the technical problems is as follows: the utility model provides a resistant composite board material of waiting, moulds the base plate including wood, it is provided with resistant layer to mould base plate both sides wood, resistant layer is back to resistant one side of moulding the base plate wood is provided with the steel structure layer, the steel structure layer is back to resistant one side on layer sets up the sealing layer, the sealing layer is back to one side on steel structure layer is provided with the flame retardant coating.
Further, the weather-resistant layer is made of a thermoplastic resin material.
Further, the steel structure layer is made of an aluminum alloy material.
Further, the steel structure layer is a honeycomb hole plate surface structure.
