Abstract
A broad-spectrum composite antibacterial agent for fabrics contains organosilicon-quaternary ammonium salt and silver chelating agent prepared by reaction of silver with ED3A. It is used in finishing fabric, terylene and sponge for higher antibacterial effect. Its advantages include high washing resistance, broad spectrum (staphylococcus, hay baciilus, colibacillus, etc.), and high effect (more than 90%).
Description
Technical field
The invention belongs to the chemical finishing agent field of textile, particularly a kind of broad-spectrum composite antibacterial agent that is used for antibacterial textile.
Background technology
U.S. Dow Corning company succeeded in developing organosilicon one quaternary ammonium salt antibacterial mildew inhibitor DC-5700 in 1972, test through more than 20 years, the DC-5700 of Dow corning is known as one of superior antibacterial agent in the present age by national defence, textile limit, and the molecular formula of the typical structure of organosilicon one quaternary ammonium salt is as follows:
On its structure, it can with cellulose fiber generation chemical bond, again can self polycondensation film forming, the fabric after the arrangement of organosilicon one quaternary ammonium salt has good antibacterial property, to the dittany bacterium, Escherichia coli, candida albicans and pseudomonas aeruginosa all have inhibit feature, and still, organosilicon one quaternary ammonium salt antiseptic belongs to non-release property, harmful bacterium that the meaning of non-release property can only be suppressed fiber itself generates, and is difficult to the skin that infected or untouchable position are produced bactericidal action; In addition, it is not good to the antibacterial effect of gram positive and negative bacterium.
The antibacterial action of silver ion is early approved by medical circle; but silver ion is unstable in air; easily oxidation is turned black; influence the outward appearance of fabric; in addition; the intermiscibility of silver ion and organosilicon one quaternary ammonium salt is very poor; the release of high concentration silver ion injures non-infected cells possibly; for improving this point; Chinese patent " ethylenediamine triacetic acid and N-acyl group ethylenediamine triacetic acid chelating agent " (CN1237975) discloses a kind of very good chelating agent; but this chelating agent is still unsettled in the normal state; be directly used in the whole oxidation stain problem that still exists of fabric fibre; if quaternary ammonium salt and silver ion can be combined, the universal and the effect of its sterilization will be more obvious.
Summary of the invention
Order of the present invention has and provides a kind of broad-spectrum composite antibacterial agent that durable antibiotic effect, antibiotic wide spectrum have bactericidal action concurrently that has.
Purpose of the present invention realizes by following scheme: broad-spectrum composite antibacterial agent, and it is the compound that comprises organosilicon one quaternary ammonium salt and silver-colored chelating agent; Described silver-colored chelating agent is that silver reacts the chelate that forms with ethylenediamine triacetic acid (ED3A); The weight proportion of above-mentioned organosilicon one quaternary ammonium salt and silver-colored chelating agent compound is 100: 10-1; Above-mentioned organosilicon one quaternary ammonium salt be structure as shown in the formula organic matter:
In the formula: R, R
1, R
2Be 1-4 carbon atom alkyl, R
3Be 8-22 carbon atom alkyl.
With the present invention clothes such as silk floss, terylene, sponge are carried out antibiotic finish, between the arrangement back weightening finish 0.05%-1%, its antibacterial effect only reduces about 10% through 50 washings, various bacteriums have been carried out antibacterial experiment, found that bacteriostasis rate to following bacterium is all more than 90%: staphylococcus, hay bacillus, Escherichia coli, tinea alba bacterium (fungi) melanomyces, Penicillium notatum, pseudomonas aeruginosa, Gram-negative, positive bacteria etc.
Specific embodiment
Embodiment 1: organosilicon one quaternary ammonium salt of selecting following molecular formula:
The alkyl of R-2-20 carbon atom in the formula, R
1The alkyl of-1～18 carbon atoms, R
2Hydrolyzable halogen atom, methoxyl group.
2% (weight) chelate solution of selecting silver and ethylenediamine triacetic acid (ED3A) is as silver-colored chelating agent, both mix with 100: 1 weight, with methyl alcohol is after solvent dilutes, cloth is handled, one soak one roll after, enter baker, the cloth after the antibiotic finish is promptly made in 120 ℃ of down oven dry.
Embodiment 2: organosilicon one quaternary ammonium salt of selecting following structure:
Select the chelate solution of the argentiferous 1% (W) that silver carbonate and ED3A reaction form, with above both in 100: 5 ratio mixing as the antibiotic finish of the fabric agent, cloth put in order by example 1 obtains antibiotic cloth.
Example example 3: have season silicon one quaternary ammonium salt and the weight proportion of silver-colored chelate be 100: 10, join dressing liquid by the method method of example 2, cloth is carried out antibiotic finish, method is the same.
Claims (4)
1. broad-spectrum composite antibacterial agent is characterized in that it is the compound that comprises organosilicon one quaternary ammonium salt and silver-colored chelating agent.
2. broad-spectrum composite antibacterial agent as claimed in claim 1 is characterized in that above-mentioned silver-colored chelating agent is the chelate of silver or silver ion and ethylenediamine triacetic acid (ED3A) reaction formation.
3. broad-spectrum composite antibacterial agent as claimed in claim 1, the weight proportion that it is characterized in that above-mentioned organosilicon one quaternary ammonium salt and silver-colored chelating agent compound is 100: 10-1.
4. broad-spectrum composite antibacterial agent as claimed in claim 1, it is characterized in that above-mentioned organosilicon one quaternary ammonium salt be structure as shown in the formula organic matter:
In the formula: R, R
1, R
2Be 1-4 carbon atom alkyl, R
3Be 8-22 carbon atom alkyl.
