Abstract

The invention discloses a corrugated honeycomb composite cardboard, comprising a honeycomb cardboard surface layer and a corrugated cardboard bottom layer, wherein a buffer layer is disposed between the two layers. The honeycomb cardboard comprises the following components by weight: 30-50 parts of hardwood pulp, 0.8-2 parts of bamboo charcoal powder, 4-10 parts of straw, 1-2 parts of epoxy resin,0.1-0.5 parts of a toughening agent, 0.4-0.8 part of a sodium hydroxide solution, 0.5-0.8 part of carboxymethyl cellulose, 0.5-1 part of a preservative and 0.01-0.02 part of ammonium ferrous sulfate.The corrugated honeycomb composite cardboard perfectly combines the advantages of the honeycomb cardboard and the corrugated cardboard, and is greatly improved in shock-absorbing buffer performance at the same time; and the corrugated honeycomb composite cardboard is prepared from a composite plant fiber material containing the hardwood pulp, the bamboo charcoal powder and the straw, has low hygroscopic moisture content, small size change and stable product performance on the premise of low density and good cushioning performance, and totally meets requirements on the cushioning materials forpackaging.

Description

technical field [0001] The invention relates to a packaging cardboard, in particular to a corrugated honeycomb composite cardboard. Background technique [0002] In the field of packaging boards, high requirements are put forward for the cushioning properties of the boards. It is necessary for the packaging boards to remain undamaged under strong impact. Honeycomb paperboard and corrugated paperboard are the most widely used packaging materials in recent years. Honeycomb paperboard flat pressing High strength and bending strength, good impact resistance, but unsatisfactory edge compressive strength and peeling degree; corrugated cardboard has edge crushing strength, high peeling degree, low production cost, high degree of mechanization, but flat crushing strength and impact resistance Poor. [0003] With the improvement of packaging requirements, ordinary honeycomb paperboard or corrugated paperboard is difficult to meet the needs of customers, especially the packaging of so...
