Description
Technical field
A kind of the present invention relates to antibiotic plastic technical field, more particularly to preparation method of nanometer silver antimicrobial plastics.
Background technology
In daily life, plastic is a lot, such as food pack, refuse bin, the cabinet of household electrical appliance, toilet
Facility, kitchen utensils etc., all easy breed bacteria, become the medium of disease propagation, therefore carry out antibiotic health care to such material
Processing tool is of great significance.Anti-biotic material is applied on anti-bacterial fibre, the eighties in 20th century, in Japan and Europe
Mei Deng developed countries start to occur in that antibiotic plastic.Antibiotic plastic is had started to for white goods, Communication Equipment, automobile system now
The aspect such as make, wherein favored using nanotechnology modified inorganic antiseptic people the most.This kind of antibacterial is super due to particle diameter
Carefully, the contact area with antibacterial is increased, while the cell wall that can penetrate antibacterial is entered in cell body, cell synzyme is destroyed
Activity, makes cell loss division growth ability and dead, so as to reach the purpose of antibacterial.
As the preparation of nano material and the preparation technology of antibacterial are closely related, and the performance of many antibacterial can be with
The reduction of the size of antibacterial particle and improve, so nanotechnology and antimicrobial technology close relation.Nanometer silver has very well
Chemical stability and biological non-toxicity, the effect of good bactericidal can be played using nanometer silver, by nano silver antimicrobials
With plastic resin homogeneous blend, plastic or plastic foil is made, antibacterial wide spectrum, the feature of long-acting, safety and stability can be become
Plastics.
Zeolite is a kind of natural nano-material, with multi-cellular structure feature.Using its architectural feature, using ion exchange
The displacement of the antibacterial metal ions such as silver ion can be entered zeolite micropore, make nano silver-carrying antiseptic by method.Nanometer silver zeolite is multiple
Antibacterial is closed as particle diameter is little, specific surface area big, there is larger surface energy, particle agglomeration phenomenon occurs easily, serious restriction
Its application in antibacterial product.Improve dispersibility of the nanometer silver zeolite complex antimicrobials in plastic substrate, it has also become grind
Study carefully the key problem in technology with exploitation antibacterial plastic product.
Content of the invention
Present invention seek to address that the deficiencies in the prior art, and a kind of preparation method of nanometer silver antimicrobial plastics is provided.
The present invention for achieving the above object, is employed the following technical solutions：A kind of preparation method of nanometer silver antimicrobial plastics, its
It is characterised by, comprises the following steps：First, antibacterial silver ion or its metal-oxide are assembled in by micropore using ion exchange method
In material nano Zeolite support, nanometer silver zeolite composite antibacterial material is obtained；Secondly, using surfactant to nanometer silver zeolite
Composite antibacterial material carries out surface modification treatment；Afterwards, it is 1 in mass ratio：5 ratio is by nanometer silver zeolite composite antibacterial material
Mix with powdered polypropylene matrix, add auxiliary agent and dispersant, decentralized processing is carried out using the method for vibromill, nanometer silver is made
Zeolite composite antibacterial plastic master batch；Finally, by nanometer silver zeolite composite antibacterial plastic master batch and polypropylene plastics in mass ratio 1：
10 ratio mix homogeneously, adds injection machine to carry out injection mo(u)lding, nanometer silver antimicrobial plastics is obtained.
The invention has the beneficial effects as follows：Method of the present invention using physical modification, with surfactant to nanometer silver zeolite
Composite antibacterial material is surface-treated, and forms one layer of coating film in particle surface, makes to reduce contact as far as possible between particle, to avoid
The generation of agglomeration, is to improve nanometer silver dispersibility in the base to lay a good foundation；Secondly, by vibromill bonus point
The method of powder carries out decentralized processing, that is, be initially charged dispersant, and the particle of dispersant forms big point by adsorbing macromolecular substances
Subchain, when particle is close, macromolecular chain can produce sterically hindered, there is provided space stability ultimate load is acted on, and then adopt vibromill
Method disperseed, material through the strong impact of abrasive media, shearing, grinding refinement, further disperse and mix, make powder
Dispersion of the body in polypropylene matrix reaches uniformly；The present invention has wide spectrum, efficient, long-acting anti-microbial property and good slow release
Performance, tensile strength, tensile modulus of elasticity, elongation at break and notch impact strength are improved.
Specific embodiment
With reference to embodiment, the invention will be further described：
The present invention provides a kind of preparation method of nanometer silver antimicrobial plastics, comprises the following steps：First, using ion exchange
Method is assembled in antibacterial silver ion or its metal-oxide in poromerics nano zeolite carrier, nanometer silver zeolite is obtained compound anti-
Bacterium material；Secondly, surface modification treatment is carried out to nanometer silver zeolite composite antibacterial material using surfactant；Afterwards, by matter
Amount is than being 1：Nanometer silver zeolite composite antibacterial material is mixed by 5 ratio with powdered polypropylene matrix, adds auxiliary agent and dispersant,
Decentralized processing is carried out using the method for vibromill, nanometer silver zeolite composite antibacterial plastic master batch is made；Finally, by nanometer silver zeolite
Composite antibacterial plastic master batch and polypropylene plastics in mass ratio 1：10 ratio mix homogeneously, adds injection machine to be molded into
Type, is obtained nanometer silver antimicrobial plastics.
Above the present invention is exemplarily described, it is clear that the present invention is implemented and is not subject to the restrictions described above,
