Embodiment approach

[0038] As an embodiment of the present invention, the weight average molecular weight of the ethyl methacrylate is between 10,000 and 50,000.

[0039] As an embodiment of the present invention, the foaming agent is azodicarbonamide, azobisisobutyronitrile, benzenesulfonyl hydrazide, dinitrosopentamethylenetetramine, diazophenylaminobenzene , urea, ammonium carbonate, sodium bicarbonate, ammonium chloride, or any mixture of several.

[0040] As an embodiment of the present invention, the modified plant fiber is obtained by modifying the plant fiber with alkyl succinic anhydride or alkenyl succinic anhydride and acylation treatment.

[0041] As an embodiment of the present invention, the alkyl succinic anhydride is selected from one or a combination of octyl succinic anhydride, dodecyl succinic anhydride, hexadecyl succinic anhydride, and octadecyl succinic anhydride.

[0042] As an embodiment of the present invention, the alkenyl succinic anhydride is selected from pentenyl su...

Abstract

The invention discloses a plant fiber foaming buffer packaging material, which is prepared from the following ingredients in parts by weight: polyvinyl alcohol resin, polyvinyl alcohol, modified plantfibber, epoxy propane, ethyl methacrylate, foaming agents, zinc oxide, sodium methyl silicate, slaked lime and polyethylene glycol. The plant fiber foaming buffer packaging material provided by the invention has the advantages that a specific formula is selected, so that the microstructure of the plant fiber is changed from the inside; the hole number and the uniformity of the foaming material ofthe buffer material are obviously improved; meanwhile, the mechanical property of the material is also improved.

Description

technical field [0001] The invention relates to a packaging material. More specifically, the present invention relates to a plant fiber foamed cushioning packaging material. Background technique [0002] EPS foam products are one of the main sources of environmental pollution. According to the "Circular Economy Promotion Law of the People's Republic of China", this product is facing elimination. However, EPS foam plastics are light in weight and flexible, and as a cushioning packaging material, there is no ideal substitute so far. [0003] At present, the main substitute is pulp molding cushioning packaging material, which uses pulp as raw material, which is formed by pulping, vacuum adsorption molding, and drying. Products are used in small electronic instruments, household appliances and other industries. However, the product is too dense, the impact resistance is poor, and the cushioning property is lower than that of EPS foamed plastic. Pulp with lots of wood. The...
