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

[0039] see figure 1 , a method for preparing a highly transparent degradable material provided by an embodiment of the present invention, which includes the following steps:

[0040] 1) Preparation of raw materials: According to weight percentage, take the following raw material components:

[0041] Main ingredients polypropylene resin 95~98, polystyrene resin 1~5, food grade benzoic acid 0.01~0.05; modified paraffin wax 0.1~0.5;

[0042] 2) Component mixing:

[0043] Firstly, the above components are prepared into 100-300 mesh powder, and dried;

[0044] Weigh 1 / 3 of the total amount of polypropylene resin, add all the food grade benzoic acid and modified paraffin, stir and mix;

[0045] Then gradually add the rest of the polypropylene resin and all the polystyrene resin and stir and mix until it is completely added, so that the powder components are evenly mixed to form a polypropylene resin modified mixture;

[0046] 3) Under low temperature conditions, the polypropylen...

Embodiment 2

[0058] The preparation method of the highly transparent degradable material provided by this embodiment is basically the same as that of Example 1, the difference is that:

[0059] Preferably, the weight percent of each component in the step 1) is: main material polypropylene resin 95-96%, modified material polystyrene resin 2-5, food grade benzoic acid 0.05, modified paraffin wax 0.2-0.5.

[0060] This embodiment provides a method for preparing a straw using the highly transparent and degradable material, which is basically the same as that of Embodiment 1, except that it also includes the following steps:

[0061] 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;

[0062] 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 provide...

Embodiment 3

[0064] The preparation method of the highly transparent degradable material provided by this embodiment is basically the same as that of Example 1, the difference is that:

[0065] The weight percent of each component in the step 1) is:

[0066] Main ingredients polypropylene resin 95, polystyrene resin 4.89, food grade benzoic acid 0.01; modified paraffin wax 0.1;

[0067] This embodiment provides a method for preparing a straw using the highly transparent and degradable material, which is basically the same as that of Embodiment 1, except that it also includes the following steps:

[0068] 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.

[0069] 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 i...

Abstract

The invention provides a preparation method of a high transparent degradable material. The preparation method is characterized by comprising the following steps of: 1) preparing raw materials: based on weight percent, weighing the following raw material components: 95-98 of polypropylene resin, 1-5 of polystyrene resin, 0.01-0.05 of food-grade benzoic acid and 0.1-0.5 of modified paraffin; 2) mixing the components to form a modified polypropylene resin mixing material; and 3) carrying out low-temperature standing on the modified mixing material for later use. The invention also discloses a method for preparing a suction tube by using the above materials. The method for preparing the suction tube comprises the following steps of: 4) preparing a suction tube extruding main machine and a round die head matched with the main machine; 5) feeding the modified mixing material in the extruding main machine to obtain a continuous round hollow suction tube; and 6) cutting the prepared continuous linear type suction tube to suction tube sections. The invention further provides the suction tube prepared by the method. The material provided by the invention is highly transparent and degradable, the method is scientific and reasonable, the production efficiency is high, the product property is good, and the cost is low.
