Abstract

The invention provides a high-temperature-resistant thermoplastic honeycomb board. The high-temperature-resistant thermoplastic honeycomb board is formed by combining an upper panel, a lower panel anda middle honeycomb core board, wherein the honeycomb core board is provided with honeycomb units. The manufacturing raw materials of the honeycomb core board comprise a base material and a high-temperature-resistant additive; a proper ratio of the particle radius R of the high-temperature-resistant additive to the wall thickness D (mm) of the honeycomb units is set to be A, wherein A=R / D; and a ratio of a mass percentage W of the high-temperature-resistant additive in the preparation raw materials to the wall thickness D (mm) of the honeycomb units is set to be B, wherein B=W / D, so that the mechanical performance bending performance retention rate of the high-temperature-resistant thermoplastic honeycomb board at a temperature of 80 DEG C is 70% or above, and the high-temperature-resistant thermoplastic honeycomb plate can be used in a high-temperature environment.

Description

technical field [0001] The invention relates to a novel high-temperature-resistant thermoplastic honeycomb plate, in particular to a thermoplastic honeycomb plate with a retention rate of more than 70% of mechanical properties and bending properties at 80°C. Background technique [0002] As a basic material in daily life, panels are found in various environments such as our living, working, and transportation. Panel technology is also constantly developing towards energy saving, environmental protection and high efficiency. Porous panels including honeycomb panels are used as a The sandwich-like structure core material has light weight and excellent mechanical properties, and has been widely used in various fields such as automobile shipping and construction engineering. The core layer of the early sandwich panels was mostly paper honeycomb. The typical advantages of paper honeycomb sandwich panels are excellent high-temperature load-bearing performance and no attenuation o...
