Abstract

The invention discloses an antibacterial temperature-sensitive straw material and a preparation method thereof. The antibacterial temperature-sensitive straw material is prepared from the following raw materials in parts by weight: 100 parts of polypropylene resin, 12-28 parts of TPE, 10-25 parts of hemp stalk fibers, 0.5-2 parts of thermochromic powder, 8-14 parts of an antibacterial composition,0.8-1.5 parts of hydroxy propyl cellulose, 4-8 parts of calcium carbonate, 1-3 parts of polyethylene wax and 0.1-0.4 parts of polycaprolactam. The melt flow rate of the polypropylene resin is 20-32 g / 10 min, and the vicat softening point is greater than or equal to 145 DEG C. The prepared antibacterial temperature-sensitive straw material is good in antibacterial performance, long in antibacterial time, sensitive to temperature induction and simple in preparation method, has certain biodegradability, and is suitable for large-scale production and processing, and the preparation process is easy to operate.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to an antibacterial temperature-sensing straw material and a preparation method thereof. Background technique [0002] With the acceleration of people's life rhythm, the consumption of various liquid foods such as milk and beverages is increasing, and straws are generally used for such foods. Polypropylene resin is a crystalline polymer with a regular structure. It is a light milky white pellet. It is a non-toxic, odorless and light-weight thermoplastic resin. It has been widely used in the plastics industry and can be used to process plastic straws. However, the straws currently on the market still have the following problems: first, they have poor temperature resistance, and they are easy to become soft or deformed when encountering hot drinks; second, they have poor antibacterial properties; The temperature often burns the mouth because the temperature is too high. ...
