Abstract

The invention discloses a degradable foam packing material. The packing material comprises the following ingredients in parts by weight: 100 parts of straw fiber, 80-86 parts of corn starch, 12-16 parts of silicon oxide powder, 24-28 parts of talcum powder, 10-16 parts of a plant fiber modifier, 5-9 parts of an organic silicon releasing agent, and 10-12 parts of a foaming agent, wherein the foaming agent is a reaction product of powdered aluminum and sodium hydroxide; the sodium hydroxide in the preparation process is a solution with the concentration of 4-6%.

Description

technical field [0001] The invention relates to the technical field of packaging materials, in particular to a degradable foam packaging material. Background technique [0002] With the gradual deepening of human's understanding of their own living environment and its influencing factors, people's awareness of environmental protection has rapidly increased. strict restrictions. At present, the cushioning packages of various industrial products in the world are mostly made of lightweight and convenient synthetic resin foam materials, such as expanded polystyrene (EPS), polyvinyl chloride (PVC) and the like. Due to the non-degradability of these materials, their waste has caused quite serious pollution to the environment. Moreover, the chlorofluorocarbon gas released by these materials during the production process has caused serious damage to the atmospheric ozone layer that humans are resistant to care. Over the years, people have been working tirelessly to find biodegrad...
