Abstract
The present invention proposes a kind of Antibacterial polypropylene composition, is prepared from by following raw material according to mass parts：100 parts of acrylic resin, 15~30 parts of filler, 0.5~1.2 part of antiseptic, 3~8 parts of toughener, 0.2~0.5 part of coupling agent, 0.1~0.3 part of antioxidant；Filler is nanomete talc powder；Antiseptic is with the attapulgite modified carrying silver antimicrobials for matrix；Toughener is styrene itaconic acid acrylic copolymer；Coupling agent is 3 aminopropyl triethoxysilanes；Antioxidant is antioxidant 1010 and antioxidant 618 according to mass ratio 1:1 mixture being mixed to get.A kind of Antibacterial polypropylene composition and preparation method thereof prepares carrying silver antimicrobials using modified attapulgite, have many advantages, such as that good dispersion, particle diameter distribution are uniform, stability is high and it is low to prepare cost, children dinning chair is prepared using Antibacterial polypropylene composition, the children dinning chair can reach more than 98% to the antibiotic rate of Escherichia coli, mould, three kinds of bacteriums of staphylococcus aureus.
Description
Technical field
The invention belongs to antibiotic plastic preparation field, more particularly to a kind of Antibacterial polypropylene composition and its preparation side
Method, application.
Background technology
In recent years, as the improvement of people's living standards, health and health consciousness constantly strengthen, plastic products are proposed
The articles for daily use of the requirement of antibacterial, particularly relation child health safety, such as children dinning chair, toy.Polypropylene is as general
One of most widely used kind in plastics, the study hotspot in antibacterial modified always antibacterial field is carried out to it.
The preparation of Antibacterial polypropylene composition, mainly by adding a certain amount of antiseptic in polypropylene granulation process
To realize.The species of antiseptic is a lot, mainly includes inorganic antiseptic, the major class of organic antiseptic two.Organic antibacterial agent has
Have the advantages that antibacterial speed is fast, scope is wide, but there is also poor heat resistance, easily ooze out, wash resistant, service life is not short, toxicity compared with
Greatly, wait not enough using harmful for a long time.Inorganic antiseptic has that antibacterial wide spectrum, security be good, heat-resist, durability
Good the advantages of, and it is easy to industrialization, the study hotspot as recent antibiotic plastic field.
Inorganic antiseptic is to be worth an obtained class using metal and its sterilizations of ion such as silver, copper, zinc or bacteriostasis
Antiseptic.In numerous inorganic antiseptics, silver has the advantages that broad-spectrum antibacterial property, sterilization of high efficiency, security performance are high so that
Silver-series antibacterial agent turns into the study hotspot in inorganic antiseptic.Silver-series antibacterial agent on the one hand can be with protein, enzyme equimolecular chela
Close or adsorb, hinder the eubolism of bacterium；Another aspect trace silver can activate the oxygen in air or water, produce activity
Oxonium ion, occurs oxidation reaction with bacterium and gas chromatography, causes the phosphodiester bond between the base in DNA to be broken,
The DNA replication dna of microbial cell is destroyed, plays a part of multiple inhibiting or eliminating bacteria, successfully overcoming organic antibacterial agent makes
The shortcomings of with short life, poor heat resistance, narrower application.
The attapulgite rich reserves of China, its storage capacity accounts for more than half of whole world gross storage capacity, its wide material sources,
It is with low cost.Attapulgite has unique chain layered crystal structure and special pore passage structure, interfacial property and larger
Specific surface area, becomes a kind of preferable carrier.But contain substantial amounts of impurity in attapulgite tcrude ore, such as montmorillonite,
Illite and carbonate etc., the absorption property of the presence influence attapulgite of impurity is, it is necessary to by purification and modification ability
Attapulgite is set to be used as high-grade sorbing material.
Therefore, to overcome the defect present in above technical scheme, the present invention propose a kind of Antibacterial polypropylene composition and
Its preparation method, application.
The content of the invention
It is an object of the invention to provide a kind of Antibacterial polypropylene composition with and preparation method thereof, application.
The present invention uses following technical scheme：A kind of Antibacterial polypropylene composition, is prepared by following raw material according to mass parts
