Abstract

The invention discloses a high buffer insulating composite paperboard which comprises a honeycomb paperboard layer, wherein a barrier film I is attached to a honeycomb paperboard, a fiber fabric layer is arranged on the barrier film I, a barrier film II is arranged on the fiber fabric layer, the barrier film II is coated with an inorganic fiber coating I, and a polylactic acid-aliphatic polyester composite foaming board is arranged on the inorganic fibber coating I; an inorganic fiber coating II is arranged below the honeycomb paperboard, a polylactic acid-elastomer composite board is arranged below the inorganic fiber coating II, and the fiber fabric layer is filled with a nano composite suspension. The composite board disclosed by the invention has an excellent anti-impact buffering effect and a good insulating effect. Meanwhile, almost raw materials of the composite board are degradable materials, so that the composite paperboard has a good environment-friendly characteristic.

Description

technical field [0001] The invention relates to the field of environment-friendly composite honeycomb paperboard, in particular to a high-buffering and heat-insulating composite paperboard with excellent cushioning performance and heat insulation performance. Background technique [0002] In the field of plate preparation, especially in the field of high-end packaging plates, there are high requirements for the comprehensive performance of the plate. For example, the plate is required to have good mechanical properties to protect against the impact of external forces, and have good barrier properties to prevent internal packaging. Oxidation, good flame retardancy, etc. Although plastic panels have good and controllable properties, they are derived from petroleum resources and are difficult to degrade, which is likely to cause long-term pollution. Therefore, a variety of environmentally friendly boards have been developed, such as common wood-plastic boards, polylactic acid ...
