Abstract

The present invention relates to a novel electronic cushioning packaging material and a preparation method thereof. The preparation method comprises the following steps: (1) mixing and stirring polyvinyl alcohol and water; (2) adding cornstarch, potato starch, tapioca starch, ramie fiber and coir, continue stirring; (3) add phosphatidylcholine, potassium sorbate, sodium bicarbonate, azodicarbonamide, epoxidized soybean oil, dioctyl phthalate, glycerol and ethanol, Stir with a mixer; (4) Pour into a mold for pre-pressing; (5) Cold press with a cold press and keep the pressure for 30-60 minutes; (6) Put it into a hot press after drying; (7) ) into a cold press for cold pressing and shaping. The prepared new electronic cushioning packaging material has excellent cushioning performance and good elasticity. At the same time, its raw materials are made of natural degradable materials, which are environmentally friendly and pollution-free.

Description

technical field [0001] The invention belongs to the field of electronic materials, and relates to a novel electronic buffer packaging material and a preparation method thereof. Background technique [0002] Cushioning packaging materials, also known as shockproof packaging materials, occupy an important position in packaging materials, mainly to prevent product damage and reduce the impact of external forces. With the rapid development of economy and technology, the electronics industry has also made great progress, and the output has reached an unprecedented huge. At present, the cushioning packaging materials used for electronic products are mainly expanded polystyrene, but the degradation capacity of polystyrene It is very poor and will cause serious environmental pollution. If it is recycled, it will take a lot of manpower and material resources. Therefore, it is of great significance to realize sustainable development to research and develop a kind of electronic cushio...
