Description
Technical field
The present invention relates to a kind of antibiotic paint that is used for frosting and preparation method thereof, and adopt this antibiotic paint to prepare the method for antibacterial plastic product.
Background technology
Consumption is big in daily life, use is wide for plastics, and those in use are vulnerable to harmful microbe with the position that human body, object frequently contact and pollute, and can constitute certain threat to people's health.Therefore, the development and application of antibiotic plastic has been set up green screen one for the protection human health, for improving environment for human survival, reduces disease, and the protection fitness-for-all has crucial meaning.The research work of antibiotic plastic starts from the eighties in 20th century, and in recent years, the antibiotic plastic of developed countries such as Japan, the U.S. and West Europe all grows a lot.Particularly Japanese, the application surface of antibiotic plastic is very wide, relates to many aspects such as household electrical appliances, food product pack, cultural goods, kitchen tackle, auto parts machinery and electric wire, again antibiotic plastic is applied in material of construction and the house decorative material now.
The antiseptic-germicide that the antibacterial effect of antibiotic plastic adopts with it has direct relation.Antiseptic-germicide is to extremely sensitive chemical ingredientss of microorganism such as some bacteriums, mould, fungi, yeast, makes an addition in the plastics, under traditional performance that does not change plastics and processing characteristics prerequisite, plays antibiotic effect.The antiseptic-germicide that is applied in the plastics can be divided into several big classes such as inorganic, organic, natural and compound.The one, inorganic antiseptic, mainly based on silver, copper, zinc plasma and some nano materials, for silver, copper, zinc metal, they mainly exist with ionic condition, combine with carrier by ion-exchange or other forms, owing to the strong binding ability at these metal ions and bacterium or mold activity center has antibacterial.The 2nd, organic antibacterial agent mainly contains fragrant aldehyde, vanillal compounds, quaternary ammonium salts and biguanides.In addition, methicillinum, alcohols, phenols, organo-metallic class, pyridine etc. also can be used as antiseptic-germicide, and dysentery bacterium, intestinal bacteria, streptococcus aureus etc. are all had the good sterilization effect.Antibiotic mechanism is that antiseptic-germicide combines with the surface of cell membrane negatively charged ion of bacterium, mould, or reacts with sulfydryl, destroys the synthesis system of protein and cytolemma, suppresses bacterium and mold propagates.The 3rd, natural antibacterial agent, mainly refinement from animals and plants, refining forming, as the extract of peppermint, Lemon Leaf etc., the chitosan that refines in crab and the shrimp etc.Chitosan be chitin take off the acetyl product, have stronger anti-microbial activity, its effective concentration value to intestinal bacteria, Bacillus subtilus and streptococcus aureus is 0.05%-0.1%.In addition, chitosan also has restraining effect to phytopathogen.The 4th, the inorganic-organic composite antibiotic agent is to be parent with the layered metal oxide, utilizes the interlayer insertion reaction, and silver complex or other organic antibacterial agents are inserted interlayer.Layered inorganic-organic antibacterial agent except that avoided painted bad, also have characteristics such as good stability, life-span length, antimicrobial efficiency height.
Antiseptic-germicide dispersed in plastics and with the consistency of plastics are keys of preparation antibiotic plastic.The preparation method of antibiotic plastic mainly contains at present: the one, and direct addition method directly adds antiseptic-germicide in the plastics, carries out forming process after mixing, and makes corresponding antibacterial plastic product.Direct addition method is simple to operate, the antiseptic-germicide addition can accurately be controlled, though being antiseptic-germicide macroscopic view in antimicrobial prod, shortcoming is uniformly dispersed, but the microscopic uniformity in plastic substrate is subjected to the restriction of material and antiseptic-germicide consistency and complete processing, antiseptic-germicide is distributed in the plastic substrate with coacervate usually, bad dispersibility, thereby anti-microbial property is relatively poor relatively.The 2nd, the antibacterial matrices method, by the twin screw extruder extruding pelletization, general concentration is 25 times or 50 times of antiseptic-germicide concentration in the antimicrobial prod with antiseptic-germicide and matrix resin (or the resin of excellent compatibility arranged with matrix resin).Material is through the shearing and the kneading of twin screw; again by processes such as moulding; improved the dispersiveness of antiseptic-germicide in antimicrobial prod; and improved consistency with matrix resin, and the antibacterial matrices that uses is particulate state, and no dust flies upward in the operation of moulding; reduced the pollution of production process; do not need during use antiseptic-germicide is carried out surface treatment, optimized the production technique of antibacterial plastic product, so antiseptic-germicide master batch refabrication antimicrobial prod is present antimicrobial prod main production methods.The 3rd, surperficial bonding method, this method and in-mold decoration processes are very approaching, and antiseptic-germicide is sprayed at the product molding die surface, and antiseptic-germicide is attached on product surface and forms antimicrobial prod during injection moulding.Sometimes also use the film or the thin slice that have added antiseptic-germicide to be placed on earlier in the forming mould, during injection moulding film or thin slice are attached on product surface formation antimicrobial prod.The 4th, laminating is prepared into antibiotic thin slice with antiseptic-germicide and plastics earlier, with the superimposed surface of plastic products of handling at needs of this thin slice, is hot pressed into required antimicrobial prod on laminating apparatus then.The 5th, post-treatment is handled, and it is to handle on the plastic component surface that post-treatment is handled, and makes it have anti-microbial property.The method that adopts has surperficial sputtering process and vacuum sputtering surface sputtering process at present.
Yet, adopt the example of complex antimicrobials less in the existing plastics, especially fail fully to study multiple antiseptic-germicide and exist the synergistic effect of germ resistance after compound, promptly several antiseptic-germicides compound back germ resistance and broad spectrum all are better than several antiseptic-germicides when using separately, and the simple arithmetic of anti-microbial effect adds and is worth; And among the preparation method of existing antibiotic plastic, it is big that direct addition method exists the antiseptic-germicide consumption, the shortcoming of bad dispersibility in plastic substrate; The antibacterial matrices method exists the antiseptic-germicide large usage quantity, the shortcoming of technology relative complex; Surface bonding method, laminating all exists the antiseptic-germicide layer and the bond matrix performance is poor; It is big that the post-treatment processing exists difficulty of processing, the high deficiency of equipment price.
Summary of the invention
The technical problem to be solved in the present invention is, provide a kind of raw material sources wide, be easy to prepare, anti-microbial property is good is used for antibiotic paint of frosting and preparation method thereof, simultaneously, provides a kind of method that adopts this antibiotic paint to prepare antibacterial plastic product.
Coat process complexity, antiseptic-germicide consumption defective how at antiseptic-germicide in the prior art, a kind of antibiotic paint that is used for frosting and preparation method thereof is provided, and adopts this antibiotic paint to prepare the method for germ resistance plastics.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of antibiotic paint that is used for frosting comprises ZnO, TiO
