Problems solved by technology

[0003] At the same time, the existing honeycomb panels also have some major problems: the combination of the honeycomb core and the panel is a T-shaped linear combination, which restricts the strength, stiffness and stability of the honeycomb panel
In addition, for the adhesive honeycomb panel, since the honeycomb core itself and the connection method between the honeycomb core and the panel are physically combined, its strength, service life and allowable working environment are largely restricted by the performance of the adhesive. In the frequent, high or low temperature working environment, the joint between the honeycomb core and the panel is easy to debond, resulting in the failure of the load during use, which is far below the yield limit of the material used, and the mechanical properties are low

Embodiment 1

[0019] The following combination figure 1 To further illustrate the present invention, a plastic honeycomb panel includes an upper panel 1, a plastic honeycomb core 2 and a lower panel 3, the upper and lower panels are PP plastic panels, and the plastic honeycomb core is made of PP material. Among them, the thickness of the upper panel is 1mm, the thickness of the lower panel is 1mm, and the thickness of the plastic honeycomb core is 15mm. The upper panel, the honeycomb core, and the lower panel are bonded into a three-layer structure by hot-melting. The temperature is set at 120°C. The pressure is set according to the line bonding between the honeycomb cores and the "T"-shaped bonding between the honeycomb core and the panel. The heating and pressing time is 18 minutes, during which a three-layer decorative material is formed by melting the material itself and curing under pressure.

Embodiment 2

Abstract

The invention relates to a plastic cellular board and a production method, the plastic cellular board comprises an upper panel, a lower panel and a plastic honeycomb core between the upper panel and the lower panel. A hot melting pressurization composite method is employed among the upper panel, the plastic honeycomb core and the lower panel for bonding to form a three-layer structure. Compared with the prior art, a step of using an adhesive can be saved, cracking and pull-off of the adhesive can be avoided due to infirm bonding and usage at high temperature, and the plastic cellular board has the functions of simple forming, sound absorption and heat insulation, and has the characteristics of light weight, environmental protection, recoverable performance and low cost.

Description

technical field [0001] The invention relates to a decorative panel in the fields of construction, furniture, automobile, aerospace and aviation, etc., in particular to a plastic honeycomb panel. Background technique [0002] Honeycomb panels have been widely used in aerospace, aircraft, trains, ships, construction and other fields due to their light weight, high strength, high rigidity, good sound attenuation and heat insulation, and good stability. Among them, the characteristics of plastic honeycomb panels are particularly prominent. It avoids the disadvantages of poor moisture resistance of paper honeycomb panels, heavy weight of stone honeycomb panels, and rusting of aluminum honeycomb panels when exposed to moisture. At the same time, it has the environmental protection requirements of recyclability. [0003] At the same time, the existing honeycomb panels also have some major problems: the combination of the honeycomb core and the panel is a T-shaped linear combination...
