Description
Technical field
The present invention relates to a kind of anti-biochemical protection composite and protective garment torn, belong to the functional composite material field with antibacterial functions.
Background technology
At present, conventional on the market protective garment is divided into isolated type protection clothes, permeability type and half permeability type protective garment usually.Conventional isolated type protection clothes have not wet thoroughly shortcoming, make the personnel's of dress physiology and psychology produce certain negative effect; Though permeability type and half breathable protective clothes are of a great variety, barrier propterty is generally lower, and limitation is big.Permeability type and half breathable protective are more superior with respect to isolation type and selective permeation protective garment comfortableness, but protective is relatively poor relatively.Now, people have added some sorbing materials in order to solve comfortableness and protective this a pair of contradiction that can not get both in the barrier layer of permeability type, half permeability type protective garment.The sorbing material that adds in permeability type protective garment and the half permeability type protective garment is the active carbon composition, and these compositions can reduce the ambient concentration of toxic agent simultaneously with the toxic agent adsorption preventing through skin infringement human body.Active carbon is present topmost sorbing material, but there is certain defective, and its physisorption exists the desorption phenomenon, and toxicant is all the time attached on the protective garment.In case protective garment is torn, toxic agent will be invaded skin.
New material, new technology, application of new have become current protective garment Development Trend.The biochemical protective garment of desirable high-performance should be able to effectively be isolated blood, body fluid, virus, bacterium etc. on the one hand, and prevents many chemical substance infiltrations, also allows water vapour molecule to pass through in a large number on the other hand simultaneously, has excellent protective and comfortableness.It is imperative to develop the biochemical protective garment of such high-performance.
Summary of the invention
The objective of the invention is, overcome the above-mentioned deficiency of prior art, a kind of anti-biochemical protective garment and preparation method thereof of tearing with antibacterial functions is provided.Technical scheme of the present invention is following:
A kind of have an antibacterial functions anti-torn biochemical protective garment preparation method, comprises the following steps:
(1) preparation nano magnesia;
(2) choose and a kind ofly anti-tear cloth, and it is carried out the waterproof oil-repellent finiss;
(3) with through the anti-cloth of tearing of waterproof oil-repellent finiss as outer supporting layer, and choose material as intermediate filter layer and nexine, between outer supporting layer and intermediate filter layer and nexine, add 5-25g/m
2Nano magnesia is prepared into biochemical protection composite with trilaminate material and nano magnesia through heat pressure adhesive;
(4) should biochemistry protection Composite Preparation become the Contiuum type protective garment, and carry out heat posted at seam crossing and close.
As preferred implementation; Protective garment preparation method of the present invention; Nano magnesia is to be primary raw material with magnesium chloride and ammoniacal liquor, is that dispersant is prepared from through the precipitation method with the polyethylene glycol, and concrete preparation method is: be in the magnesium chloride ethanol solution of 0.1-0.5mol/L in concentration; The volume ratio of adding and solution is that dispersant polyethylene glycol and the concentration of 0.04-0.1 is the acetum of 0.1-0.2mol acetic acid/L; Under 60 ℃ of constant temperatures, mix, and slow dropping ammonia and absolute ethyl alcohol mixed solution, make it generate white depositions; With processing white presoma after white depositions filtration that generates and the drying, its grinding and calcining are made nano oxidized magnesium dust; Prevent that tearing cloth is processed by terylene/polyvinyl blending; With polypropylene fibre melt spraying non-woven fabrics or polytetrafluoroethylcomposite composite film is intermediate filter layer, is nexine with material in the mesh.
The present invention provide simultaneously a kind of adopt that above-mentioned preparation method processes have an antibacterial functions anti-ly tear biochemical protective garment; This kind protective garment is a kind of Contiuum type protective garment of being processed by biochemistry protection composite; The biochemical protection of this kind composite is divided into three layers: outer supporting layer, intermediate filter layer, nexine is characterized in that outer supporting layer wherein is by processing through the anti-cloth of tearing of waterproof oil-repellent finiss; Between trilaminate material, be added with nano magnesia, addition is 5-25g/m
2
Provided by the inventionization protective garment and preparation method thereof is the degraded sorbing material with the nano magnesia, can not only adsorb toxic agent, and it is less or do not have the material of toxicity also can it to be degraded into toxicity, reduces the injury to wearer.Under the prerequisite that guarantees the biological protection effect; In order to improve degradation property and the bacteriostasis property of protective garment to chemical substance, the present invention has prepared nano magnesia through the precipitation method, and its degradation effect to the chemical substance paraoxon is obvious; When 5min, paraoxon has been degraded 99.19%.The nano magnesia of preparation added in the trilaminate material carries out laminate adhesive, so preparation have an antibacterial functions anti-ly tear biochemical protective garment.Adopt the biochemistry protection composite of method preparation of the present invention to have higher anti-tear resistance, laterally tear load between 150~190N, longitudinal tear load is between 140~170N.Biochemical protection composite all more than 94%, shows that it has good biocidal property to bacillus subtilis var bacterium, gold-coloured staphylococci and colibacillary bacteriostasis rate.The biochemical protective garment of the present invention preparation reaches as high as 100% to NaCl aerosol strainability, to microorganism X-174 bacteriophage pressure difference be 0 with 1.75kPa down the clump count of maintenance 5min be respectively 0 and 1.5.Explain and wearing the safety that this protective garment can guarantee the wearer.The thermal resistance mean value of biochemical protective garment is 0.22clo, and wet resistance mean value is at 33.82-36.9m
2Pa/W.Show that this biochemistry protective garment under the prerequisite that guarantees excellent biochemical protection effect, has improved wearer's comfortableness.
