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

[0052] see figure 1 , a kind of preparation method of biomass degradable material provided by the embodiment of the present invention, it comprises the following steps:

[0053] 1) Preparation of raw materials: According to weight percentage, take the following raw material components:

[0054] Main material polybutylene succinate 40-60, modified polylactic acid 40-60, filler calcium carbonate masterbatch 0.1-20;

[0055] 2) Component mixing:

[0056] Firstly, the above components are prepared into 100-300 mesh powder, and dried;

[0057] Weigh the polybutylene succinate of 1 / 3 of the total amount, add all the polylactic acid, stir and mix;

[0058] Then add the remaining polybutylene succinate and all the calcium carbonate masterbatch gradually and stir and mix until it is completely added, so that the powder components are evenly mixed to form a modified polybutylene succinate mixed material;

[0059] 3) Vacuumize the modified polybutylene succinate mixture under low te...

Embodiment 2

[0071] The preparation method of the biomass degradable material provided by this embodiment is basically the same as that of Example 1, the difference is that:

[0072] The weight percentage of each component in the step 1) is: 40-50% polybutylene succinate as main material, 40-50% polylactic acid as modified material, and 1-10% calcium carbonate masterbatch as filler.

[0073] A method for preparing a straw using the biomass-degradable material provided in this embodiment is basically the same as in Example 1, except that it also includes the following steps:

[0074] 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;

[0075] 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

[0077] The preparation method of the biomass degradable material provided by this embodiment is basically the same as that of Example 1, the difference is that:

[0078] The weight percent of each component in the step 1) is:

[0079] The main material is polybutylene succinate 40, the modified polylactic acid, and the filler calcium carbonate masterbatch 20.

[0080] A method for preparing a straw using the biomass-degradable material provided in this embodiment is basically the same as in Example 1, except that it also includes the following steps:

[0081] 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.

[0082] 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 biomass degradable material preparation method. 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: 40 to 60 percent of poly(butylene succinate) serving as a main material, 40 to 60 percent of polylactic acid serving as a modified material and 0.1 to 20 percent of calcium carbonate master batch serving as a filler; 2) mixing the components to form a modified poly(butylene succinate) mixed material; and 3) standing the modified mixed material at a low temperature for later use. The invention also discloses a method for preparing a straw by using the material, which comprises the following steps of: 4) preparing a straw extruding main machine and a circular die head which is matched with the main machine for use; 5) feeding the modified poly(butylene succinate) mixed material into the extruding main machine to obtain a continuous circular hollow straw; and 7) cutting into straw sections. The invention also provides the straw which is prepared by the method. The material provided by the invention can be completely degraded; the method is scientific and rational and has high production efficiency; and a product has high performance and is low in cost.

Description

technical field [0001] The invention relates to biodegradable materials and products thereof, in particular to a method for manufacturing a degradable material using polybutylene succinate as the main material, and a straw prepared by using the material. Background technique [0002] In recent years, drinking straws have been used as disposable hygiene products in catering tools, and the market demand is very large. According to incomplete statistics, the annual plastic straws used in the world are more than 500,000 tons, and the traditional plastic straws are mainly polypropylene. (PP) is the raw material, which cannot be degraded after use; as the society pays attention to white pollution and people's environmental awareness increases, in the near future, straws made of traditional plastic will be generally restricted by countries all over the world. , a wide range of material sources, easy to decompose after use without polluting the environment, and the performance is cl...
