Abstract

The invention discloses a degradable foaming package material. The degradable foaming package material comprises, by weight, 40-75 parts of poly-beta-hydroxybutyrate, 8-16 parts of poly(butanediol succinate), 12-42 parts of modified plant fibers, 1-4 parts of foaming agents, 2-4 parts of inorganic powder and 1-6 parts of fusion agents. The modified plant fibers are obtained by drying plant fibers under 2-5MPa at the temperature of 220-240 DEG C under the protection of inert gases to achieve the water content of 3-5% and subjecting the plant fibers to 5-10 minutes of electromagnetic radiation under the protection of the inert gases after smashing. The degradable foaming package material has the advantages of high tensile strength, high elongation at break, high impact resistance, biodegradability, non-existence of environment pollution and the like, thereby being capable of replacing polyolefins-type foaming package materials.

Description

technical field [0001] The invention relates to raw packaging materials, in particular to a degradable foam packaging material. Background technique [0002] Plastics are widely used, such as plastic bottles, plastic packaging, plastic bags, etc. Many packaging materials in our lives are plastic products. 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, serious "white pollution" has been caused, which has brought huge pressure to the environment; moreover, polystyrene EPS uses non-renewable petrochemical resources as raw materials, and petrochemical resources are facing increasing energy shortages. crisis. Therefore, this is undoubtedly a material that is contrary to low-carbon economy and sustainable development, and it is urgent to seek a new, degradable and environmentally friendly ma...
