Abstract

The invention discloses a degradable foam packaging material and its preparation method. The packaging material comprises, by weight, 8-10 parts of degradable resin, 1-2 parts of a modifier, 2-3 parts of a foaming agent, 70-80 parts of vegetable fiber and 4-5 parts of inorganic powder. The preparation method comprises the following steps: 1, preparing raw materials according to the above formula; 2, drying the vegetable fiber; 3, carrying out ultrafine treatment on the vegetable fiber, and preparing a modified vegetable fiber composite base material; 4, carrying out low temperature high shearing on the modified vegetable fiber composite base material; 5, pre-foaming the modified vegetable fiber composite base material; 6, carrying out foaming extrusion on the modified vegetable fiber composite base material; and 7, cooling and fixing to obtain the degradable foam packaging material. The degradable foam packaging material has the advantages of high strength, good toughness, low density, economy, environmental protection and the like.

Description

technical field [0001] The invention belongs to a packaging material, in particular to a degradable foam packaging material and a preparation method thereof. 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 polyolefin foam materials, such as expanded polystyrene EPS, polyvinyl chloride PVC, etc. 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. For many years, people have been [0003] There is a tireless search for biodegradable, lightweight a...
