Abstract

The invention relates to a preparation method of a high-strength type foaming and cushioning packaging material and belongs to the technical field of preparation of packaging materials. The preparation method provided by the invention is characterized in that bamboo pulp is taken as a main body and is subjected to pulping treatment and then fermentation modification; by virtue of fermentation treatment, internal pores of the material are greatly increased, and the specific surface area is increased; furthermore, by virtue of fermentation, bamboo pulp fibers are effectively decomposed and saccharified, and the formed saccharified liquid improves the gel network of the starch material, increases the expansion properties of the material, effectively increases the structure density of the gelmaterial and modifies the mechanical properties of the composite material; by performing pulping treatment on the bamboo pulp fibers, the fibers are cut off and are mutually extruded to generate a large number of fine fibers; and because the fine fibers contain a large number of hydroxyl groups, the hydrogen bonding degree among the fibers is effectively increased, the bonding strength among the fibers is effectively increased, the formed fiber network is richer, and the curl degree and the adhesive force of the fibers are effectively increased, thereby greatly increasing the mechanical properties of the material.

Description

technical field [0001] The invention relates to a preparation method of a high-strength foam cushioning packaging material, which belongs to the technical field of packaging material preparation. Background technique [0002] Cushion packaging materials have a relatively short life cycle and are often discarded after their job of protecting the product reaches the consumer. Therefore, from the perspective of protecting the environment, environmentally friendly cushioning packaging materials are the main direction of future development and research. For now, the research categories of environmentally friendly cushioning packaging materials mainly include: starch and degradable plastics, and plant fiber-based degradable cushioning materials. Due to the limitations of molding equipment and other aspects in domestic research on plant fiber foaming cushioning materials, chemical foaming agents are generally used. First, the foaming agent is evenly distributed in the material sys...
