Plastic composite board and preparation method thereof

Abstract

The invention relates to a plastic composite board and a preparation method thereof. The plastic composite board comprises a plastic outer layer, wherein a plurality of reinforcing rib boards are uniformly distributed on the plastic outer layer in a fusing manner, and the reinforcing rib boards and a plastic body in the plastic outer layer can form a whole in the fusing manner. The structural plastic composite board is adopted, the plurality of reinforcing rib boards are uniformly distributed on the plastic outer layer, the whole intensity of the plastic composite board is amplified, the plastic composite board is widely applied to building materials such as floor boards, ceilings, door plates, and wall decorative boards, and the structure is simple and reasonable.

Description

technical field [0001] The invention relates to boards for decoration and construction, in particular to a plastic composite board with anti-corrosion and environmental protection and a preparation method thereof. Background technique [0002] At present, the boards in architectural decoration or industrial applications generally use ordinary wooden plywood, aluminum-plastic board or other pure plastic boards. Since the wooden plywood is composed of multi-layer bonding, a large amount of industrial glue and paint must be used, which is prone to produce harmful substances such as formaldehyde. ; while the aluminum-plastic panel has good flatness, low price, good sound insulation and heat insulation effect, and more and more people pay attention to it, but it still has the following disadvantages: it is not fireproof, and the product size is limited, low hardness, easy to bond Defects cause glue opening, falling off, and poor weather resistance. Moreover, when the existing abo...

[0002] At present, the boards in architectural decoration or industrial applications generally use ordinary wooden plywood, aluminum-plastic board or other pure plastic boards. Since the wooden plywood is composed of multi-layer bonding, a large amount of industrial glue and paint must be used, which is prone to produce harmful substances such as formaldehyde. ; while the aluminum-plastic panel has good flatness, low price, good sound insulation and heat insulation effect, and more and more people pay attention to it, but it still has the following disadvantages: it is not fireproof, and the product size is limited, low hardness, easy to bond Defects cause glue opening, falling off, and poor weather resistance. Moreover, when the existing above-mentioned boards reach a certain length, the overall board surface is prone to deformation or distortion when they are stored for a long time or unreasonable, which causes inconvenience to use and increases construction difficulty.

[0003] The new wood-plastic board also adopts the following structural methods: 1), the plastic raw materials are mixed with fiber powder (such as wood powder or bamboo powder, etc.), and then pressed to form a board; 2), the plastic board is added with foam 3) The surface of the plastic board is pressed with wear-resistant layer, wood veneer, etc.; 4) The surface of the plastic board is covered with glass fiber. The above four structures cannot solve the internal structural defects of the plastic board. Effectively improve the strength of the plastic board
