Problems solved by technology

At present, the more mature honeycomb composite panels are mainly aluminum honeycomb, paper honeycomb and thermoplastic honeycomb. Recyclable, waterproof, corrosion-resistant and other characteristics, widely used in various material fields such as building materials, vans, automobiles, decorations, etc.
However, the thermoplastic material itself has the disadvantages of being not resistant to ultraviolet rays and oxidation. It will age under long-term sunlight exposure, and various physical properties will be greatly reduced, which affects the service life and safety of thermoplastic honeycomb panels.

Abstract

The invention discloses an anti-ultraviolet honeycomb composite board. The honeycomb composite board comprises a honeycomb board core material, a honeycomb board panel and a honeycomb board panel basebottom film, wherein the honeycomb board panel is compounded together with the honeycomb board core material through the honeycomb board panel base bottom film; the honeycomb board panel is made of the following components in parts by weight: 40 to 100 parts of thermoplastic material, 0.5 to 1.5 parts of coupling agent, 0.5 to 2 parts of dispersing agent, 0.1 to 5 parts of ultraviolet light absorber and 0.1 to 5 parts of radical scavenger; the honeycomb board panel base bottom film is made of the following components in parts by weight: 90 to 100 parts of glass fiber cloth material, 0.5 to 1.5 parts of coupling agent, 0.5 to 2 parts of dispersing agent and 0.1 to 5 parts of quenching agent; the honeycomb board core material is made of the following components in parts by weight: 40 to 100 parts of thermoplastic material, 0.5 to 1.5 parts of coupling agent, 0.5 to 2 parts of dispersing agent, 0.1 to 3 parts of hydroperoxide decomposer and 0.1 to 3 parts of radical scavenger. In the honeycomb composite board, different light stabilizers are added, so that the honeycomb composite board has an ultraviolet absorption capability, the negative effect of ultraviolet radiation on the honeycomb composite board is lowered, and the service life of the honeycomb composite board is prolonged.

Description

technical field [0001] The invention relates to a composite board and a preparation method thereof, in particular to a honeycomb composite board with an anti-ultraviolet function and a preparation method thereof. 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 thermoplastic material itself has the disadvantages of being not resistant to ultraviolet ...
