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

preparation example Construction

[0033] A preparation method of a degradable composite material containing coffee grounds, comprising the following steps:

[0034] S1. Mix coffee grounds, natural adhesive material or artificially synthesized water-soluble degradable polymer material and coagulant to form a mixture;

[0035] S2. Making the mixture into the required product shape through mechanical molding or extrusion molding or manual molding;

[0036] S3. Baking and curing the formed product at a low temperature or drying it naturally.

Embodiment 1

[0038] Feed 1 kg of fresh wet coffee grounds (from Starbucks, with a moisture content of 48.5% in the test) into the blender, start stirring, and then feed 550 g (100 mesh) of food-grade gum arabic powder. The upper mold is molded into a cake shape with a diameter of 3 cm and a thickness of 1 cm. Dry at room temperature for 24 hours to fully harden and form. Weighing before and after hardening, it is calculated that the dry coffee grounds content in the finished product after full hardening is 46%. The finished product is stored at room temperature for 6 months, and it still has a strong coffee aroma. After testing, put the sample block into clean water at room temperature, and after 40 minutes, it will be completely dissociated.

Embodiment 2

[0040] Feed 500 grams of dried coffee grounds (wet coffee grounds from Starbucks, used after drying, test moisture content is less than 2%) into the mixer, start stirring, and then feed 300 grams of guar gum powder and paste glutinous rice glue 500 gram (commercially available), after completely mixing evenly, the material is taken out, and molded on a mold to form a block with a thickness of 2 cm * 2 cm * 2 cm. Heat and dry in a 50-degree oven for 5 hours, and then it can be completely hardened and formed. After hardening, it is weighed, and the content of dry coffee grounds in the finished product is calculated as 60%. The finished product has been placed in the car for 3 months, and it still has a pleasant coffee aroma. After testing, the finished product was soaked in water, and after 2 hours, the block disintegrated.

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...
