Example Embodiment
[0018] Example 1
[0019] The weight content of each raw material component in the biodegradable straw is:
[0020]
[0021] The preparation process of the biodegradable straw is as follows:
[0022] (1) Add 6.3 parts of bamboo powder to the high-speed mixer, set the temperature of the equipment to 80℃, and set the stirring speed to 500r / min. After turning on the equipment, slowly add 0.6 parts of aluminum titanium coupling agent from the feeding port and continue stirring After 10 minutes, turn off the equipment to form a bamboo powder pretreatment material.
[0023] (2) According to the set ratio, add 80 parts of PLA and 10 parts of PHA to the high-speed mixer. The mixing speed is set to 100r / min. After turning on the equipment, first add 2 parts of epoxy soybean oil, and then sequentially Add bamboo powder pretreatment material, lubricant and anti-hydrolysis agent, and continue to stir for 10 minutes to form a polylactic acid mixture.
[0024] (3) The polylactic acid mixture is add...
