Problems solved by technology

However, bacteria are extremely easy to multiply on the surface of the transparent plastic water storage container for storing water, which will cause the bacteria in the softened water stored in the water storage container to exceed the standard and produce peculiar smell, which will have a great adverse effect on the cleaning and sanitation of tableware
[0003] In response to the above problems, the current common measure is to add antibacterial materials to transparent plastics, such as zeolite-loaded silver and zinc oxide. However, although these antibacterial materials can improve the antibacterial performance of the surface of transparent plastic water tanks, they will also greatly reduce the life of the water storage container. Transparency, which is not conducive to observing the working conditions and subsequent maintenance of other parts in the water storage container

preparation example Construction

[0042] The preparation method provided by the embodiment of the present invention includes the step of mixing the raw materials and then performing granulation by a twin-screw extruder.

[0043] Further, the raw materials are mixed by mechanical stirring, the stirring speed is 100-400 rpm, and the stirring time is 2-5 min.

[0044] Further, during the granulation process of the twin-screw extruder, the temperature range is controlled at 160-240°C.

[0045] It depends on the type of transparent plastic particles:

[0046] When the transparent plastic particles are polypropylene or polyethylene terephthalate-1,4-cyclohexane dimethanol ester copolymer, the process parameters of the twin-screw extruder granulation are: the temperature of the first zone: 160-180℃ , the temperature of the second zone: 170-190℃, the temperature of the third zone: 180-200℃, the temperature of the fourth zone: 180-200℃, the temperature of the fifth zone: 180-200℃, the temperature of the sixth zone: 18...

Embodiment 1

[0053] This embodiment provides an antibacterial transparent material, the raw material of which is composed of transparent plastic particles PP and antibacterial agents 2-n-octyl-4-isothiazolin-3-one, 2-n-octyl-4-isothiazoline The weight ratio of -3-one to PP was 0.8:100.

[0054] The present embodiment also provides the preparation method of the above-mentioned antibacterial transparent material, and the steps are as follows:

[0055] Accurately weigh 2-n-octyl-4-isothiazolin-3-one and PP according to the above proportions and transfer to a high-speed mixer with a stirring speed of 100 rpm and a stirring time of 3 min. After stirring and mixing evenly, transfer to a twin-screw extruder. Machine feeding hopper ready for extrusion granulation;

[0056] The twin-screw extrusion granulation process parameters are as follows: the temperature of the first zone: 170 °C, the temperature of the second zone: 180 °C, the temperature of the third zone: 180 °C, the temperature of the fo...

Embodiment 2

[0059] This embodiment provides an antibacterial transparent material, the raw material is composed of transparent plastic particles PCTG and antibacterial agent polyhexamethyleneguanidine hydrochloride, and the weight ratio of polyhexamethyleneguanidine hydrochloride to PCTG is 1.0:100.

[0060] The present embodiment also provides the preparation method of the above-mentioned antibacterial transparent material, and the steps are as follows:

[0061] Accurately weigh the polyhexamethyleneguanidine hydrochloride and PCTG according to the above proportions and transfer them to a high-speed mixer. The stirring speed is 300 rpm and the stirring time is 4 min. grain;

[0062] The twin-screw extrusion granulation process parameters are as follows: the temperature of the first zone: 180 °C, the temperature of the second zone: 190 °C, the temperature of the third zone: 190 °C, the temperature of the fourth zone: 190 °C, the temperature of the fifth zone: 190 °C, the temperature of th...

Abstract

The invention relates to the field of high polymer materials, and provides an antibacterial transparent material, a preparation method thereof, a water storage container and a dish-washing machine. Raw materials of the antibacterial transparent material comprise transparent plastic particles and an antibacterial agent, and the antibacterial agent is one or more of polyhexamethylene guanidine hydrochloride, polyhexamethylene biguanide hydrochloride, isothiazolinone and a quaternary ammonium salt antibacterial agent. According to the invention, specific types of antibacterial agents, specifically at least one of polyhexamethyleneguanidine hydrochloride, polyhexamethylenebiguanide hydrochloride, isothiazolinone and quaternary ammonium salt antibacterial agents, are selected, so that the long-acting antibacterial effect is realized, and the light transmittance of the original transparent plastic particles is hardly reduced.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to an antibacterial transparent material and a preparation method thereof, a water storage container and a dishwasher. Background technique [0002] With the rapid development of the household appliance industry and the continuous improvement of the quality of life, dishwashers are becoming more and more popular. Among them, the transparent plastic water storage container in the dishwasher is to store the softened water for supplying the dishwasher to complete the washing work. However, bacteria are extremely easy to multiply on the surface of the transparent plastic water storage container that stores water, which will cause the softened water bacteria stored in the water storage container to exceed the standard and produce peculiar smell, which has a great adverse effect on the washing and hygiene of tableware. [0003] In view of the above problems, the usual measure a...
