Abstract
The invention discloses a preparation method for a biological source-based air purifying and filtering screen. The preparation method comprises the steps of baking, blending, stirring, melting extrusion, cooling, drawing and setting of materials; powder prepared from Chinese herbal medicines including solidago decurrens, lotus leaves, syzygium aromaticum and illicium verum, with high sterilizing power and wide antibiotic spectrum, is added in the blending link, so that the filter screen produced by weaving monofilaments has better purifying and sterilizing effects after being proved by severe tests.
Description
Technical field
The present invention relates to a kind of screen pack, particularly relate to a kind of biogenic base cleaning filtration screen of air and preparation method.
Technical background
Increasing research shows, air pollution has become the huge problem of facing mankind, brings direct or potential harm to the work of people and life.Current purification of air, mainly based on dedusting, even if be provided with sterilizing unit, also mainly adopts disinfection by ultraviolet light or with chemosterilant sterilization etc.But no matter carry out disinfection by physical method or chemical method, all larger excitant and harmfulness are produced to human body, and bactericidal effect is limited.Applicant is in production practices for many years, the air cleaning unit of continuous research and development environment-friendly and green, start with from the resourceful Chinese herbal medicine with better bactericidal effect, develop a kind of not only can dedusting but also the microorganism can killed in air, and the biogenic base air filter net to human non-toxic's side effect.
Summary of the invention
The object of this invention is to provide a kind of preparation method of biogenic base cleaning filtration screen of air.
The object of the invention is to be achieved through the following technical solutions:
(1) baking expects that spinning-grade plastic resin master batch (as polypropylene or polyethylene) is put into 50 DEG C of-100 DEG C of dryers dries;
(2) batching is greater than 25% of extract weight to the powdered active component content of the Extracts from Plant Recourses participating in batching, fineness of powder is the screen cloth of 0.065mm by aperture, the 3%-5% that plant source powdered extract presses plastic resin master batch weight adds, and its addition requires according to antimicrobial levels and the content of plant source powdered extract active component is selected;
(3) compound prepared by weight proportion stirs by stirring;
(4) melt extrude and well-beaten batching is put into plastic extruder by melt extruding monofilament after preheating, thawing, plasticizing, calculating, spray wire process, melt extruding filament temperature is 150 DEG C-320 DEG C;
(5) monofilament melt extruded is put into 30 DEG C of-40 DEG C of tanks and is cooled by cooling;
(6) cooled monofilament is put into hauling machine and is drawn by traction, and traction temperature is 95 DEG C-115 DEG C;
(7) monofilament drawn is put into forming machine and is shaped by sizing, and setting temperature is 95 DEG C-115 DEG C;
After implementing above-mentioned technological process, the biogenic airstrainer monofilament that the average diameter that the present invention relates to is 0.2mm can be obtained.Its ultimate strength is greater than 880CN, elongation at break 20%-50%;
Described plant source powder is made up of the Chinese herbal medicine of following weight portion: goldenrod 7-11 part, lotus leaf 15-21 part, cloves 9-14 part, Chinese anise 7-12 part.
Preferred: Chinese herbal medicine goldenrod 9 parts, 18 parts, lotus leaf, cloves 12 parts, Chinese anise 10 parts.
Preparation method
Being pulverized by said herbal medicine raw material is 60 orders, adds the ethanol water that appropriate concentration is 95%, soaks 40 hours; The solidliquid mixture ultrasonic assistant of process is extracted, ultrasonic temperature is 50 DEG C, supersonic frequency is 30kHz, ultrasonic wave extraction time is 40 minutes; Then by solidliquid mixture suction filtration under 30kPa vacuum condition, get filtrate decompression distillation under 30kPa vacuum, 45 DEG C of conditions, reclaim ethanol, obtain the mixture containing extract component and water; Evaporating, concentrating and drying is to powdery again, then pulverizes by adding technology requirement.
The characteristic of each Chinese herbal medicine
Herba Solidaginis extract: have different inhibitory action to staphylococcus aureus, pneumococcus, Pseudomonas aeruginosa and Shu Shi, sonne bacillus.
Lotus leaf ethanol extract: demonstrate stronger oxidation resistance, hydrogen peroxide can be eliminated significantly, peroxide decomposition is avoided to produce free radical, it contains a large amount of flavonoids and polyphenols, Lotus Leafextract is all inhibited to bacterium, yeast, mould, sour environment and alkaline environment comparatively remarkable.
Flos Caryophylli extract: the sterilization and disinsection effect with wide spectrum.
Chinese anise alcohol extract: similar to potassium salt of penicillin 20 units per ml to gram-positive bacterium (staphylococcus aureus, pneumococcus corynebacterium diphtheriae etc.) bacteriostasis, similar to streptomycin sulphate 50 units per ml to gramnegative bacterium (hay bacillus, Escherichia coli, comma bacillus and injury, paratyphoid, shigella dysenteriae etc.) bacteriostasis, the bacteriostasis of fungi is greater than to benzoic acid and the salicylic acid of 1%.
Beneficial effect of the present invention: disastrously enter in plastics to make monofilament by full and uniform for Chinese herbal medicine extract, there is lasting Antibacteria effect, and to human non-toxic's side effect, the filter applications be made up of monofilament is extensive, can be used for air-conditioning, air cleaner, air freshener, also can replace gauze etc.
Detailed description of the invention
Spinning-grade plastic resin master batch is put into 70 DEG C of dryers dry, plant source powdered extract fineness of powder is the screen cloth of 0.065mm by aperture, active component content should be greater than 25% of extract weight, add by 4% of plastic resin master batch weight, after the compound prepared by weight proportion is stirred, put into plastic extruder by after preheating, thawing, plasticizing, calculating, spray wire process, be 200 DEG C of extruded monofilaments in melt temperature, put into 35 DEG C of tanks to cool, put into hauling machine 100 DEG C time, carry out traction sizing.The preparation method of plant source powder is as follows, take Chinese herbal medicine goldenrod 90 grams, 180 grams, lotus leaf, cloves 120 grams, Chinese anise 100 grams, pulverizing is 60 orders, add the ethanol water that appropriate concentration is 95%, soak 40 hours, extract with ultrasonic assistant, ultrasonic temperature is 50 DEG C, frequency is 30kHz, extraction time is 40 minutes; Then by solidliquid mixture suction filtration under 30kPa vacuum condition, get filtrate decompression distillation under 30kPa vacuum, 45 DEG C of conditions, reclaim ethanol, obtain the mixture containing extract component and water; Evaporating, concentrating and drying is to powdery again, then pulverizes by adding technology requirement.
Experiment material Linyi City one Milk Products Plant, between powder connecting vehicle, air inlet has installed airstrainer of the present invention, every day connecing the east between powder (S1), south (S2), west (S3), north (S4), 4 places sample.Adopt 9cm plating medium, expose 15min, at 37 DEG C, cultivate 52h, calculate air bells laid clump count, Continuous plus 8 days.The sedimentation clump count recorded before not installing with airstrainer of the present invention is contrast (CK).
Airstrainer of the present invention is connecing the sterilization result between powder.Unit: individual/plate
After connecing and having installed airstrainer of the present invention between powder, drop into the settling bacteria of air in producing at continuous 8 days and gone detection, result as shown above.As can be seen from statistics, after airstrainer of the present invention has been installed, there is pole significant difference (P<0.01) with contrasting in air bells laid bacterium colony, namely airstrainer of the present invention has killing action clearly to the microorganism in environment.
