Abstract
The invention relates to the field of polymer compound processing, and specifically relates to a masterbatch and a manufacturing method. The sulfur antimicrobial masterbatch comprises a masterbatch matrix manufactured by a composite plastic material containing a sulfur material. The manufacturing method of the sulfur antimicrobial masterbatch comprises the following steps of: 1) mixing of the composite plastic material: the composite plastic material containing the sulfur material is put in a stirrer for stirring at a low temperature of less than 80 DEG C to obtain a mixed material; and 2) the extrusion granulation of the mixed material: the mixed material is added to a twin-screw extruder to be subjected to extrusion and granulation by low-temperature die head heat cutting to obtain the sulfur antimicrobial masterbatch. With the technical scheme, the masterbatch prepared by the invention has the advantages of low cost, small addition amount of an antimicrobial material, obvious antimicrobial effect, low-temperature preparation and the like.
Description
Technical field
The present invention relates to the macromolecular compound manufacture field, be specifically related to a kind of master batch and method of manufacture.
Background technology
The preparation of anti-biotic material, particularly antibiotic plastic, film and non-woven fabrics normally adopt and add the antiseptic-germicide realization.The antibacterial efficacy of antiseptic-germicide and goods usefulness are directly related.Antiseptic-germicide in the market mainly is divided into three major types: inorganic antiseptic, organic antibacterial agent and natural antibacterial agent.
1) inorganic antiseptic: the antibacterial ability that utilizes metals such as silver, copper, zinc; Through methods such as physical adsorption IXs; Antiseptic-germicide is processed on the surface that metals such as silver, copper, zinc (or its ion) is fixed on porous materials such as fluorite, silica gel, then it is joined the material that promptly obtains to have antibacterial ability in the corresponding articles.Metals such as mercury, cadmium, lead also have antibacterial ability, but harmful; Copper, nickel, brill plasma have color, and with influencing the attractive in appearance of product, zinc has certain bacterinertness, but its antibacterial strength is merely 1/1000 of silver ions.
Silver ion antimicrobial agent occupies dominant position in inorganic antiseptic.Silver ions class antiseptic-germicide is the most frequently used antiseptic-germicide, the fine powdered that is white in color, and heat resisting temperature can reach more than 1300 ℃.The carrier of silver ions class antiseptic-germicide has zirconium phosphate, zeolite, pottery, gac etc.Sometimes in order to improve synergy, add some cupric ions, zine ion again.But the cost of silver ion antimicrobial agent is higher.
Inorganic antiseptics such as zinc oxide, cupric oxide, primary ammonium phosphate, Quilonum Retard are arranged in addition.
2) organic antibacterial agent: the principal item of organic antibacterial agent has Vanillin or vanillal compounds, is usually used in the polyethylene kind food packaging film, plays anti-microbial effect.Also have anilid class, imidazoles, thiazoles, isothiazolones verivate, quaternary ammonium salt, two croak class, phenols etc. in addition.The security of organic antibacterial agent at present still under study for action.In general the organic antibacterial agent poor heat resistance is a little, hydrolysis easily, and validity period is short.
3) natural antibacterial agent: natural antibacterial agent is mainly from the extraction of natural phant, quantity seldom, the application in being unfavorable for producing in enormous quantities.
