Description
Technical field
This application involves chopsticks field more particularly to a kind of antibiotic plastic chopsticks.
Background technology
Chopsticks are a kind of food fetching tools, and are convenient for carrying, but due to being not easy to keep dry after longer or cleaning
Only, surface easily grows bacterium, and when reusing, healthy and safe to user brings hidden danger.
Invention content
The present invention is intended to provide a kind of antibiotic plastic chopsticks, set forth above to solve the problems, such as.
A kind of antibiotic plastic chopsticks are provided in the embodiment of the present invention, including chopsticks ontology, which is characterized in that the chopsticks
Sub- ontology is equipped with antibacterial resin, and the antibacterial resin obtains antibacterial plastic concentrate to be first kneaded antiseptic and resin, then by antibacterial
Masterbatch and resin are kneaded, and obtain the antibacterial resin by the techniques such as being molded, squeezing out, the resin is acrylic resin, described
Antiseptic to carry silver zinc copper zeolite antibacterial agent, silver in the antiseptic, zinc, copper molar ratio be 3：1：2, the antiseptic grain size
It is 6 μm.
The technical solution that the embodiment of the present invention provides can include the following benefits：
The present invention is equipped with antibacterial resin on chopsticks ontology, has to Escherichia coli and staphylococcus glucose bacterium apparent
Bactericidal effect, simultaneously because the use of additive, the color changeable effect unobvious of the antibacterial resin, so as to solve set forth above ask
Topic.
The additional aspect of the application and advantage will be set forth in part in the description, and will partly become from the following description
It obtains significantly or is recognized by the practice of the application.It should be understood that above general description and following detailed description are only
It is exemplary and explanatory, the application can not be limited.
Description of the drawings
Using attached drawing, the invention will be further described, but the embodiment in attached drawing does not form any limit to the present invention
System, for those of ordinary skill in the art, without creative efforts, can also obtain according to the following drawings
Other attached drawings.
Fig. 1 is the production process figure of antibacterial resin of the present invention.
Specific embodiment
Here exemplary embodiment will be illustrated in detail, example is illustrated in the accompanying drawings.Following description is related to
During attached drawing, unless otherwise indicated, the same numbers in different attached drawings represent the same or similar element.Following exemplary embodiment
Described in embodiment do not represent and the consistent all embodiments of the present invention.On the contrary, they be only with it is such as appended
The example of the consistent device and method of some aspects being described in detail in claims, of the invention.
It is ubiquitous due to harmful levels of pathogens in production and living, very big threat is caused to people's health.Utilize sterilization
It is the effective way for preventing spread of germs that anti-biotic material, which inhibits and kill the growth of harmful bacteria, breeding,.Currently, anti-biotic material has been
Through being widely used in the daily production and life of people, such as applied in plastic product and sanitary ware.
Anti-biotic material is a kind of new material to microorganism with powerful killing ability or rejection ability, extensively should
For in people's daily life and industrial and agricultural development, at present, anti-biotic material more to refer to add certain antibacterial material --- it is anti-
Microbial inoculum, so as to the ability for making material that there is inhibition or killing is attached to its surface microorganism of itself, such as anti-bacteria ceramic, antibacterial
Metal, anti-bacterial fibre, antibiotic plastic etc..
Antiseptic is generally divided into organic antibacterial agent and inorganic antiseptic.Organic antibacterial agent is with organic acid, phenols, quaternary ammonium
The organic matters such as salt are the antiseptic of antimicrobial component, and inorganic antiseptic is mainly to be resisted using what the metals such as silver, copper, zinc had in itself
The metals such as silver, copper, zinc the methods of by physical absorption or ion exchange, are fixed on the surface or hole of porous material by bacterium ability
In road, it is then added into product and obtains the material with antibiotic property.Wherein, organic antibacterial agent effectively can inhibit to have and fall ill
Bacterium, mould result from breeding, quick, but there are stability it is poor, easily decompose, persistence is poor, toxicity is big the shortcomings of, for a long time
Using harmful；Inorganic antiseptic is the emphasis studied at present, has many advantages, such as hypotoxicity, heat resistance, persistence, is fine
The life product suitable antibacterial kind such as dimension, plastics, building materials.
In addition, zeolite is the crystalline aluminosilicate also known as molecular sieve of a kind of alkali or alkaline earth metal, structure is silicon
The three dimensional skeletal structure that oxygen tetrahedron and aluminum-oxygen tetrahedron share oxygen atom and form has larger specific surface area, due to bone
Aluminium in frame-oxygen tetrahedron electricity price is uneven, and to reach electrostatic equilibrium, the metal cations such as sodium, calcium must be combined in structure,
It can be partially or completely exchanged by other cations so that zeolite has very strong cation exchange capacity (CEC)；When preparing zeolite antibacterial agent, will boil
Stone is impregnated in solution, and the zeolite structured interior alkali or alkaline earth metal ion of silver ion displacement utilizes the antibiotic property of silver ion
It can so that zeolite has antibacterial ability.
It needs to improve however, existing Ag Loaded Zeolite Antimicrobial still has antibacterial ability, anti-tarnishing ability is not strong, stability
The problems such as poor.
Application scenarios one：
Embodiments herein is related to a kind of antibiotic plastic chopsticks, including chopsticks ontology, which is characterized in that the chopsticks sheet
Body is equipped with antibacterial resin, and the antibacterial resin obtains antibacterial plastic concentrate to be first kneaded antiseptic and resin, then by antibacterial plastic concentrate
