Embodiment 1

[0051] The preparation method of the liquid storage antibacterial material of the embodiment of the present invention comprises:

[0052] (1) Add zeolite to 18wt% NH at a solid-to-liquid ratio of 1:8g / mL 4 In Cl solution, soak for 6 hours at 50°C, clarify, remove the supernatant, and then add an equal volume of NH 4 The Cl solution was soaked at 95 °C for 1 h, and the filter residue was washed with distilled water after suction filtration, and the filter residue was dried at 100 °C to obtain NH 4+ type zeolite;

[0053] (2) NH 4+ Type zeolite was added to the Cu-containing 2+ and Zn 2+ In the mixed solution, react at a constant temperature at 20°C for 12h, and wash with deionized water after suction filtration until there is no Cu 2+ Filter out to obtain the zeolite antibacterial agent;

[0054] (3) Mix and melt the zeolite antibacterial agent, polypropylene and grafted polypropylene at a weight ratio of 2:1:0.5 at 150-250°C, extrude the spline in the extruder, and pelle...

Embodiment 2

[0060] The preparation method of the liquid storage antibacterial material of the embodiment of the present invention comprises:

[0061] (1) Add zeolite to 22wt% NH at a solid-to-liquid ratio of 1:12g / mL 4 In Cl solution, soak for 5 hours at 80°C, clarify, remove the supernatant, and then add an equal volume of NH 4 Digest the Cl solution at 100°C for 2 hours, wash the filter residue with distilled water after suction filtration, and dry the filter residue at 110°C to obtain NH 4+ type zeolite;

[0062] (2) NH 4+ Type zeolite was added to the Cu-containing 2+ and Zn 2+ In the mixed solution, react at a constant temperature at 80°C for 2h, and wash with deionized water after suction filtration until there is no Cu 2+ Filter out to obtain the zeolite antibacterial agent;

[0063] (3) Mix and melt the zeolite antibacterial agent, polypropylene and grafted polypropylene at a weight ratio of 2:1.2:0.7 at 150-250°C, extrude the splines in the extruder, and cut into pellets af...

Embodiment 3

[0069] The preparation method of the liquid storage antibacterial material of the embodiment of the present invention comprises:

[0070] (1) Add zeolite to 20wt% NH at a solid-to-liquid ratio of 1:10g / mL 4 In Cl solution, soak for 8 hours at 60°C, clarify, remove the supernatant, and then add an equal volume of NH 4 The Cl solution was soaked at 105°C for 1.5h, the filter residue was washed with distilled water after suction filtration, and the filter residue was dried at 105°C to obtain NH 4+ type zeolite;

[0071] (2) NH 4+ Type zeolite was added to the Cu-containing 2+ and Zn 2+ In the mixed solution, react at a constant temperature of 60 ° C for 4 h, and wash with deionized water after suction filtration until there is no Cu 2+ Filter out to obtain the zeolite antibacterial agent;

[0072] (3) Mix and melt the zeolite antibacterial agent, polypropylene and grafted polypropylene at 200°C according to the weight ratio of 5:3:1.5, extrude the sample in the extruder, an...

Abstract

The invention discloses a liquid storage antibacterial material and a preparation method thereof as well as a liquid storage antibacterial cup. The preparation method disclosed by the invention comprises the following steps: firstly, preparing an antibacterial agent into master batch; then adding the master batch into plastic and extruding and molding. According to the preparation method disclosedby the invention, the antibacterial agent and a plastic base material are prepared into the high-concentration antibacterial master batch and then the antibacterial master batch and the plastic are mixed and melted and then are subjected to injection molding on a plastic injection molding machine to prepare antibacterial plastic; the antibacterial agent is uniformly dispersed in a final product and has good dispersity; the problem that the dispersity of the antibacterial agent is poor, caused by a direction adding method, can be avoided; a production technology of an antibacterial plastic product is also optimized; furthermore, the antibacterial performance of the product is improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a liquid storage antibacterial material, a preparation method thereof, and a liquid storage antibacterial cup. Background technique [0002] Currently, urine collection within 24 hours is generally required for the examination of a patient's kidney function. The inspection items are also advanced from the initial extensive testing items such as blood urea nitrogen and creatinine to more detailed testing items such as 24-hour urine microprotein, 24-hour uric acid, and 24-hour electrolytes. However, there is currently no unified regulation on the containers used in the 24-hour urine testing items, and patients often prepare them by themselves. Therefore, the quality and cleanliness of the container have become the number one enemy of quality inspection. And in order to reduce the impact of preservatives on the test results, the use of preservatives has been cancelled. Th...
