Detailed Description

The technical solution of the present invention is further illustrated by the following examples. The examples do not specify particular techniques or conditions, and are performed according to the techniques or conditions described in the literature in the art or according to the product specifications. The reagents or instruments used are not indicated by the manufacturer, and are all conventional products commercially available.

In the embodiment, the tea fiber can be purchased from the market or made by the self, the tea fiber is obtained from at least one of tea stalk, tea leaves or tea dust, and the tea stalk and the tea leaves are processed by the following processes: step 1: picking fresh tea leaves; step 2: drying fresh tea leaves in the sun or oven; and step 3: crushing the dried or baked tea leaves into powder, namely tea fibers by using a crusher, wherein the tea leaves comprise reusable tea stems and tea dust, and specifically, the tea stems and the tea dust can be one or the mixture of the two; preferably, the powdered tea fiber with 80-150 meshes is screened for standby. The raw materials are environment-friendly, can directly contact with food, the tea fibers have natural tea fragrance, are particularly suitable for producing tea-containing appliances, tea-brewing appliances or tea-sealing appliances, the toughness and strength of the product meet the requirements, the tea fiber content of the product is high, the product can be degraded in the natural environment, and particularly, the product can be directly used as a fertilizer for agricultural products, tea trees, grasslands and the like after being crushed after being used for 1 to 2 years. For convenience of comparison, the model of the die is a cylindrical can, and the die-casting product is not limited to the can, and other cups, gift boxes and the like only need to be replaced by corresponding dies.

Preparing a tea fiber product can, comprising the steps of:

step 1: weighing the components according to the table 1;

step 2: placing the tea fiber, the filler and other raw materials into a stirrer, stirring for 5-15 minutes to obtain a mixture after uniform stirring,

and step 3: putting the mixture into a die, heating to 160 ℃ in a die casting machine, adjusting the pressure to 175Mpa, carrying out die-casting molding, shaping for 20s, curing, taking out a product, and finishing and polishing to obtain the product;

and 4, step 4: and (6) packaging after detection and inspection.

Wherein the tea fiber is extracted from at least one of tea stem, tea leaf or tea dust; the filler is any one or combination of any more of calcium carbonate, dolomite, silica, mica, food-grade magnesium oxide and calcium silicate.
