An environmentally friendly thermoplastic circular tube composite board

Abstract

The invention discloses an environmentally-friendly thermoplastic tubular composite plate, which comprises a composite circular tube layer and a panel layer, wherein the panel layer is fixed on both ends of the composite circular tube layer by heat bonding, and the composite circular tube layer is composed of The inner tube layer is a high melting point material layer, the outer tube layer is a low melting point material layer, and the outer tube layer is heated by heat bonding to form a large rubber tumor end, the large rubber tumor end is bonded to the panel layer; the inner circular tube layer is a high melting point material layer, and the inner circular tube layer is heated and heat-bonded to form a small rubber tumor end The inner side of the small rubber tumor is provided with a water-swellable material layer; and the water-swellable material is provided with a filling layer. Compared with the prior art, the composite panel of the present invention has strong sound insulation and waterproof performance, and can withstand a large pressure.

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...
