Degradable composite material containing coffee grounds and preparation method thereof

Abstract

The invention discloses a degradable composite material containing coffee grounds and a preparation method thereof. According to the technical scheme, coffee grounds, a natural adhesive material or an artificially synthesized water-soluble degradable high polymer material and a coagulator are included, during preparation, the raw materials are evenly mixed to form a mixture, and then the mixture is made into a required product shape through mechanical mold pressing or extrusion molding or manual molding, and finally, low-temperature baking curing or natural air-drying curing is carried out on the molded product. According to the scheme, both wet coffee grounds and dry coffee grounds can be utilized, the preparation method is simple and rapid, the fragrance of the coffee grounds can be reserved and utilized, meanwhile, processing and manufacturing are simple, energy is saved, environment friendliness is achieved, and the prepared composite material product is good in strength and can be degraded conveniently and rapidly.

Description

technical field [0001] The invention relates to the technical field of biomass waste recycling and degradable materials, in particular to a degradable composite material containing coffee grounds and a preparation method thereof. Background technique [0002] Coffee is one of the three major beverages in the world, but whether it is the coffee grounds discharged during the production of instant coffee or the coffee grounds generated in the coffee shop, its subsequent treatment is a problem. Dried coffee grounds account for more than 60% of the weight of coffee beans. According to public information, Starbucks alone produces more than 200 tons of coffee grounds every day. With the increase in the number of coffee drinkers in China and the popularity of more coffee shops, the amount of coffee grounds has also increased significantly. At present, most of the coffee grounds are discarded as garbage, which will not only cause waste of resources, but also cause a certain degree o...

Problems solved by technology

Although this application has expanded the recycling value of coffee grounds, there are still many problems: coffee grounds can be degraded, but polymer materials such as polypropylene and melamine are very difficult to degrade (polypropylene is also the main type of white pollution. Polymer, difficult to degrade under natural conditions)

Obviously such reuse is neither environmentally friendly nor economically beneficial (compared with coffee grounds, in wood powder, bamboo powder and rice husk powder, except for cellulose, lignin, the content of other components is very low, except for dry crushing , no other processing is necessary)
