Abstract

The invention provides a thermoplastic honeycomb wave-absorbing board and a preparation method thereof. The thermoplastic honeycomb wave-absorbing board comprises: a surface skin; a bottom skin; The bottom skin is attached to each other, and the wave-absorbing honeycomb core is prepared by blending wave-absorbing materials and engineering plastics. In the thermoplastic honeycomb wave-absorbing board of the present invention, the wave-absorbing honeycomb core is blended with wave-absorbing materials and engineering plastics, extruded continuously by an extruder, and formed into a hexagonal honeycomb core structure through a specific mold for the honeycomb core. Method By blending and doping a small amount of wave-absorbing materials, the wave-absorbing honeycomb core has good wave-absorbing properties. Compared with the traditional method of spraying or impregnating wave-absorbing coatings on the surface of the honeycomb core, it can reduce the amount of resin and solvent used, and the prepared The thermoplastic honeycomb wave-absorbing board has the effect of light weight and environmental protection, and has important commercial value.

Description

technical field [0001] The invention relates to the technical field of wave absorbing materials, in particular to a thermoplastic honeycomb wave absorbing plate and a preparation method thereof. Background technique [0002] At present, the honeycomb absorbing panel is made by spraying or dipping a certain amount of absorbing paint on the aramid honeycomb wall, and finally covering the upper and lower skins on the surface of the absorbing honeycomb. The prepared honeycomb panels have excellent absorbing properties and mechanical properties, but spraying or dipping absorbing coatings on the surface of the honeycomb cores have problems such as complicated procedures and environmental pollution. [0003] Based on the technical problems existing in the current honeycomb absorber, it is necessary to improve it. SUMMARY OF THE INVENTION [0004] In view of this, the present invention proposes a thermoplastic honeycomb wave absorbing board and a preparation method thereof, so as...
