Embodiment 1

[0042] (1) Drying material: The antistatic agent should be fully dried before adding, and dried in a dryer with a set temperature of 70~80°C for 4 hours.

[0043] (2) Ingredients: prepared according to the following proportions: 95.9% synthetic resin PC+ABS raw materials, 0.9% glass carrier silver-based inorganic antibacterial agent, 2.5% polymer permanent antistatic agent, 0.2% antioxidant, 0.5% coupling agent.

[0044] (3) Stirring: The ingredients mixed in proportion are stirred evenly by a high-speed mixer within the temperature range of 190°C~230°C.

[0045] (4) Pelletizing: Extrude through a twin-screw granulator, pass through a cooling water tank and a blow dryer, and finally pelletize to obtain an antibacterial and antistatic plastic masterbatch.

[0046] (5) Injection molding: The prepared plastic masterbatch is set according to the base material to set various molding parameters such as mold temperature, pressure, time, etc., and the mold is used for injection moldi...

Abstract

The invention relates to an antibacterial and anti-static financial POS machine plastic casing and a preparation method thereof. The POS machine plastic casing comprises the following compositions: 95.8-96.8% of synthetic resin, 0.5-1.0% of glass carrier silver inorganic antibacterial agent, 2-2.5% of macromolecular permanent antistatic agent, 0.2% of antioxidant, and 0.5% of coupling agent. The preparation method comprises the steps of material drying, material matching as per the ratio, stirring, pelleting and injection molding, so as to prepare the POS machine plastic casing with the antibacterial and anti-static functions. The POS machine plastic casing is excellent in antibacterial and anti-static performance, has a simple structure, and is easy to manufacture and produce.

Description

technical field [0001] The invention relates to an antibacterial and antistatic financial POS machine plastic shell and a preparation method thereof. Background technique [0002] At present, the shell of financial POS machines used in medical institutions is frequently touched by users, and most of the users are patients, which leads to serious bacterial growth on the shell, which becomes the source of bacteria transmission, and ultimately affects the health of users. [0003] At the same time, the harm of static electricity to specific groups of people is far greater than that of ordinary people. For example, persistent static electricity can cause the pH value of human blood to increase, the amount of calcium excretion in urine to increase, and blood calcium to decrease. It is the most harmful to the health of pregnant women. The level of progesterone in pregnant women decreases, making them prone to fatigue, irritability and headaches; the elderly are more susceptible to...
