Abstract

The invention relates to a heat insulation corrugated material and a preparation method thereof. The heat insulation corrugated material is composed of a surface layer, a core layer and a base layer. The surface layer and the core layer, and the core layer and the base layer are adhered by an adhesive. The heat insulation corrugated material is characterized in that: at least one layer of the adhesive between the surface layer and the core layer, and between the core layer and the base layer is the adhesive with a foaming function. The surface layer, the core layer and the base layer are adhered through the adhesive, under spray steaming of 90-120DEG C steam or heating, the adhesive layer with the foaming function blisters, and at the same time the adhesion firmness is not affected, or after a molded product is formed, then blistering is carried out under spray steaming of 90-120DEG C steam or heating. Compared with the prior art, the heat insulation corrugated material provided by the invention has the advantages of good heat insulation performance and the like.

Description

technical field [0001] The invention relates to a packaging material, in particular to a heat-insulating corrugated material and a preparation method thereof. Background technique [0002] After nearly 150 years of hard work around the world, corrugated cardboard technology has continued to deepen. The development of the existing corrugated cardboard industry has reached its limit, and the supply and demand of corrugated cardboard boxes are seriously oversupplied. The corrugated cardboard box industry has been ahead of the speed of economic development. As far as the country is concerned, there are too many equipments, fierce competition, low efficiency, and low technical threshold, which have led to a long-term serious surplus of corrugated boxes and a single product structure. [0003] Corrugated materials have always been used for low-end packaging. The level of scientific research and production technology is backward, the technical threshold is low, and the competition...
