Environmental-friendly thermoplastic circular tube composite board

Abstract

The invention discloses an environmental-friendly thermoplastic circular tube composite board. The environmental-friendly thermoplastic circular tube composite board comprises a composite circular tube layer and panel layers, the panel layers at fixed at both ends of the composite circular tube layer by heat bonding, the composite circular tube layer is provided with an inner circular tube layer and an outer circular tube layer, the inner circular tube layer is a high-melting-point material layer, and the outer tube layer is a low-melting-point material layer, both ends of the outer circular tube layer are heated by heat bonding to form large adhesive fillet ends, the large adhesive fillet ends are connected with the panel layers in an adhesive mode; the inner circular tube layer is the high-melting-point material layer, both ends of the inner circular tube layer are heated by heat bonding to form small adhesive fillet ends, the small adhesive fillet ends are provided with water expanding material layers; and filling layers are arranged in the water expanding materials. Compared with the prior art, the composite board provided by the invention has high sound insulation and waterproof performance, and can bear large pressure at the same time.

Description

technical field [0001] The invention relates to the field of composite panels, in particular to an environment-friendly thermoplastic circular tube composite panel. Background technique [0002] Honeycomb composite panels are widely used in the field of building materials due to their light weight and high strength. At present, the more mature honeycomb composite panels are mainly aluminum honeycomb, paper honeycomb and thermoplastic honeycomb, but the price and weight of aluminum honeycomb are high, the application cost is high, the strength of paper honeycomb is low, and the scope of application is small, while thermoplastic honeycomb panels have Recyclable, waterproof, corrosion-resistant and other characteristics, it is widely used in various material fields such as building materials, vans, automobiles, and decorations. However, the existing honeycomb panels have low strength and poor waterproof performance. Contents of the invention [0003] The present invention i...
