Degradable biomass fiber composite packaging product and preparation process thereof

Abstract

The invention belongs to the technical field of degradable packaging materials, and particularly relates to a degradable biomass fiber composite packaging product and a preparation process thereof. The degradable biomass fiber composite packaging product provided by the invention is prepared from the following components in parts by weight: 100 parts of straw powder; 30-50 parts of hemp fiber powder; 10 to 20 parts of starch; 6 to 12 parts of gamma-chloropropyl methyl diethoxy silane; 10 to 20 parts of polylactic acid; 20-40 parts of methacrylic acid epoxy resin; 4 to 10 parts of triethylene tetramine; 4-8 parts of ammonium bicarbonate; 3-6 parts of sodium abietate; the total amount of other auxiliaries is not more than 12 parts. The degradable biomass fiber composite packaging product is economical in cost, wide in raw material source and good in degradability, the degradation period in a conventional natural environment is 8-20 months, the packaging strength requirement is met, and long-term harm to the environment is not caused after the degradable biomass fiber composite packaging product is abandoned. The preparation process of the degradable biomass fiber composite packaging product provided by the invention has the advantages of simple steps, convenience in manufacturing and convenience in automatic batch production.

Description

technical field [0001] The invention belongs to the technical field of degradable packaging materials, and in particular relates to a degradable biomass fiber composite packaging product and a preparation process thereof. Background technique [0002] With the deepening development of modern industry and the rapid progress of the Internet economy and logistics system, the packaging industry is booming, and packaging materials are widely used in various industries. There are many types of packaging materials commonly used at present, including paper bags, cartons, wooden boxes and other materials, plastic packaging materials such as polyethylene, polypropylene, polystyrene, and other packaging materials such as metal, ceramics, and glass. Among them, although paper products and wood products have certain degradability, they are difficult to regenerate in a short period of time, which greatly limits large-scale use; materials such as metal, ceramics, and glass are difficult to...

Problems solved by technology

Among them, although paper products and wood products have certain degradability, they are difficult to regenerate in a short period of time, which greatly limits large-scale use; materials such as metal, ceramics, and glass are difficult to degrade, and are expensive, which limits large-scale use; Although there are many types of plastics and their prices are relatively low, plastic products are usually difficult to degrade. At present, waste plastic products are mainly disposed of in landfills, causing serious pollution to the environment.
