Problems solved by technology

The inner hole medium of the honeycomb panel is air. Although each honeycomb unit is an independent space, there is no convection with the adjacent honeycomb unit, and there is a certain degree of heat preservation, but the inner space of the two panels in each unit space still produces convection. Therefore, its thermal insulation performance is relatively poor
The sound insulation performance is even worse, mainly relying on the two panels to play the role of sound insulation.
Therefore, these honeycomb panels are far from meeting the needs of modern engineering.
Filling the honeycomb core with insulating material can make up for the above deficiencies, but there is no industrialized continuous production process for filling the honeycomb with insulating material, thus hindering the popularization and application of this technology

Abstract

The continuous production process of honeycomb card board with stuffing includes the following steps: covering the lower facing layer to the stretched and settled honeycomb card core, filling light granular or powdered sound and heat insulating material into the honeycomb card core via constant vibration, scraping the upper surface of the honeycomb card core to eliminate excessive stuffing, covering the upper facing layer, and cutting. The present invention features filling the light granular or powdered sound and heat insulating material into the honeycomb card board. The stuffing is light porous material with certain adsorption and can speed the curing of the adhesive.

Description

technical field [0001] The invention relates to a continuous production process and a production device of a paper honeycomb panel with fillers. Background technique [0002] Honeycomb paperboard is made of honeycomb paper core coated with glue on both sides and compounded with a layer of paper or other panel materials. Many technical records including the patent publication number CN2518676 produce the production technology of honeycomb paperboard. The inner hole medium of the honeycomb panel is air. Although each honeycomb unit is an independent space, there is no convection with the adjacent honeycomb unit, and there is a certain degree of heat preservation, but the inner space of the two panels in each unit space still produces convection. Therefore, its thermal insulation performance is relatively poor. The sound insulation performance is even worse, mainly relying on the two panels to play the role of sound insulation. Therefore, these honeycomb panels are still far...
