Abstract

The invention relates to the technical field of automobile spare and accessory parts, specifically to a composite bacteriostatic agent for the interior of an automobile and a preparation method thereof. The preparation method for the composite bacteriostatic agent for the interior of the automobile comprises the following steps: allowing starch to react with sodium phytate so as to obtain starch-sodium phytate nanoparticles; subjecting the starch-sodium phytate nanoparticles to adsorption modification with diatomite so as to obtain modified starch-sodium phytate nanoparticles; and compoundingthe modified starch-sodium phytate nanoparticles with graphene modified amoxicillin so as to obtain the composite bacteriostatic agent for the interior of the automobile. The composite bacteriostaticagent for the interior of the automobile provided by the invention has long-acting bacteriostatic and antibacterial effects, can effectively inhibit the propagation of indoor bacteria, is free of toxic and side effects on the human body, and is environmentally-friendly.

Description

technical field

[0001] The invention relates to the technical field of auto parts, in particular to a composite antibacterial agent used in the interior of an automobile and a preparation method thereof. Background technique

[0002] With the development of social economy, automobiles have become a common means of transportation. When the vehicle is running, people often close the windows in order to improve the ride comfort, so that the interior of the automobile becomes a closed environment. They all gather on the surface of the car door, which is easy to produce peculiar smell, thus causing a large number of bacteria and germs (mite, staphylococcus, legionella, cold virus) to breed. These harmful substances, along with the air circulation in the car, enter the human body through breathing, causing Respiratory system infection, decreased body resistance, severe symptoms such as dizziness, fatigue, nausea, etc., especially for the elderly and children are particularly harmf...

Examples

preparation example Construction

[0019] The present invention also provides a kind of preparation method of the composite antibacterial agent used in automobile interior, comprising the following steps:

[0020] (1) dissolving starch in water, then adjusting the pH of the system to 5.3-6.1 to obtain a starch solution, adding sodium phytate to the starch solution, and stirring for 2-5 hours to obtain starch-sodium phytate nanoparticles;

[0021] (2) Calcining diatomite at 300-500°C for 1-4h to obtain calcined diatomite, then mixing the calcined diatomite, silane coupling agent and starch-sodium phytate nanoparticles in water, and Stirring and reacting at 60-80°C for 0.5-3 hours to obtain modified starch-sodium phytate nanoparticles;

[0022] (3) Ultrasonically disperse graphene oxide in ethanol for 15 to 30 minutes to obtain a graphene suspension, adjust the pH of the system to 7.6 to 8.5, and then add 1-(3-dimethylaminopropyl)-3-ethyl carbon Diimine, N-hydroxysuccinimide and amoxicillin are stirred and react...
