Problems solved by technology

The biodegradable plastics currently on the domestic market are mainly biodegradable plastics, which are biodegradable plastics made by blending general-purpose plastics such as polyethylene and polypropylene with degradable polymers such as starch. In the soil or directly under the action of sunlight and microorganisms, the high molecular weight polyolefin does not degrade, but only the starch mixed in it biodegrades, thus leaving ring-shaped cavities on the plastic products

Abstract

The invention discloses an environment-friendly degradable coffee shell fiber stirring rod. The invention also discloses a preparation method of the environment-friendly degradable coffee shell fiber stirring rod, which comprises the following steps: heating the seaweed gel powder to 60-70 DEG C, stirring until no water vapor is evaporated, adding the glycerol and the microcrystalline cellulose into the seaweed gel powder, and continuously stirring for 10-20 minutes to obtain a seaweed gel compound; adding coffee shell powder, corn bran powder, rice flour, cassava starch, glucose, polyvinyl alcohol and glycerol into the seaweed gel compound, and stirring in a water bath at 80-90 DEG C for 10-30 minutes at the stirring speed of 1000-2000r / min to obtain a coffee shell mixture; and extruding and granulating the coffee shell mixture, molding at 80-90 DEG C, cooling, pulling, cutting, drying and cooling to obtain the environment-friendly degradable coffee shell fiber stirring rod. The environment-friendly degradable coffee shell fiber stirring rod is degradable and does not cause harm to the ecological environment, and various physical and mechanical indexes can be close to or reach the performance of a common material.

Description

technical field [0001] The invention relates to the technical field of degradable materials, in particular to an environmentally friendly and degradable coffee shell fiber stirring rod and a preparation method thereof. Background technique [0002] Many countries around the world have the habit of drinking coffee. Disposable plastic coffee sticks and related products are also part of the largest plastic waste that is thrown away. Eventually, these discards will be carried by rain into creeks and then into the sea. These plastics The structure of polymer materials is very tight, and it generally takes 300-600 years to degrade in the natural environment, so a large number of these wastes pollute the environment all over the world. As people get used to using cheap plastic material products, plastic material waste will increase rapidly at a rate of about 15% per year, which will cause cumulative damage to the global environment. [0003] In order to reduce this kind of polluti...
