Problems solved by technology

[0002] In recent years, drinking straws are used as disposable sanitary products in catering tools, and the market demand is very large. According to incomplete statistics, the plastic straws used in the world every year are more than 500,000 tons, and the traditional plastic straws are mainly made of polypropylene. (PP) is the raw material, which cannot be degraded after use; as the society pays attention to white pollution and the improvement of people's environmental awareness, in the near future, straws made of traditional plastics will be generally restricted by countries all over the world. , a wide range of sources of materials, easy to decompose after use without polluting the environment, and its performance is close to that of plastic straw replacement products will become the mainstream of future development

Embodiment 1

[0038] see figure 1 , a method for preparing a degradable biomass material provided by an embodiment of the present invention, which includes the following steps:

[0039] 1) Preparation of raw materials: According to weight percentage, take the following raw material components:

[0040] The main ingredient is 79-99% starch, the modified material is 0.5-1% gum arabic powder, and the filler is 0.1-20% calcium carbonate; wherein the starch is prepared from millet, corn, and cassava as raw materials, and its water content is lower than 5%.

[0041] 2) Component mixing:

[0042] Firstly, the above components are prepared into 100-300 mesh powder, and dried;

[0043] Weigh 1 / 3 of the total amount of starch, add all the gum arabic powder, and stir to mix;

[0044] Then gradually add the rest of the starch and all the calcium carbonate and stir and mix until it is completely added, so that the powder components are evenly mixed to form a colloidal mixture;

[0045] 3) Vacuum the...

Embodiment 2

[0055] The preparation method of the degradable biomass material provided in this example is basically the same as Example 1, the difference is:

[0056] The weight percent of each component in the step 1) is: main ingredient starch 80-90 percent, modified material gum arabic powder 1 percent, filler calcium carbonate 9-20 percent.

[0057] This embodiment provides a method for preparing a straw using the degradable biomass material, which is basically the same as that of Embodiment 1, except that it also includes the following steps:

[0058] 6) An elbow forming machine is prepared, and the pipe body of the continuous straw is subjected to an elbow indentation process to obtain a bendable straw in the middle;

[0059] The straw prepared by the above-mentioned method provided in this embodiment is basically the same as that in Example 1, the difference lies in that the middle part of the straw is provided with creases for bending the straw.

Embodiment 3

[0061] The preparation method of the degradable biomass material provided in this example is basically the same as Example 1, the difference is:

[0062] The weight percent of each component in the step 1) is: main ingredient starch 80, modified material gum arabic powder 0.5, filler calcium carbonate 19.5.

[0063] This embodiment provides a method for preparing a straw using the degradable biomass material, which is basically the same as that of Embodiment 1, except that it also includes the following steps:

[0064] 9) A scoop forming machine is prepared, and the cutting part of the tube body of the continuous straw is subjected to a scoop-shaped indentation process to obtain a scoop-shaped straw at one or both ends.

[0065] The straw prepared by the above method provided in this example is basically the same as that in Example 1, the difference is that the section of the straw at one or both ends is spoon-shaped.

Abstract

The invention provides a method for preparing a degradable biomass material. The method is characterized by comprising the following steps of: (1) preparing raw materials, namely weighing the following raw material components in percentage by weight: 79 to 99 percent of starch serving as a main material, 0.5 to 1 percent of arabic gum serving as a modified material and 0.1 to 20 percent of calcium carbonate serving as a filler; (2) mixing the components to form a gummy mixture; and (3) and standing the gummy mixture at a low temperature for later use. The invention also discloses a method for preparing a straw by using the material; and the method comprises the following steps of: (4) preparing a straw extrusion main machine and a circular die head which is matched with the main machine for use; (5) feeding the gummy mixture into the extrusion main machine to prepare a continuous circular hollow straw; and (7) cutting the prepared continuous straight straw into straw sections. The invention also provides the straw prepared by the method. The material provided by the invention has the advantages of complete degradation, scientific and rational method, high product performance and low cost.
