Abstract
The anti-bacterial mylon raw material is made by using (wt.%): 93.89-98.97 nylon 1010, adding 1-6 anti-bacterial agent and adding 0.02-0.05 acetous acid and 0.01-0.06 phosphorous acid in a polymerizer. After evacuation, charging carbondioxide gas, heating, dewatering, injection to mould band, dicing cutting and drying so as to form the nylon raw material mother particles which contain anti-bacterial agent uniformly. Said invented nylon raw material can be extensively used in prodn. of everyday use articles which possess good anti-bacterial function.
Description
The present invention relates to the production method that a kind of raw material of anti-bacteria nylon is the nylon master batch.
The nylon 1010 salt that is powdery is used preceding process polymeric kettle and comminutor granulation earlier usually, makes the nylon raw material that is beneficial to suitability for industrialized production, i.e. the nylon master batch.This master batch is made nylon sheet through hot press again, or nylon yarn is made in the wire drawing of process wire drawing machine, after through being processed into manufactured goods and medicine equipments such as toothbrush, though the product that this nylon raw material is made is nontoxic, but itself is not antibiotic yet, for example: with the tooth brush monofilament that this raw material is made, after brushing teeth once more, a large amount of assorted bacterium can breed on tooth brush monofilament, pollute the oral cavity when re-using and cause disease.
Therefore.The objective of the invention is: provide a kind of production method of raw material of anti-bacteria nylon, so that evenly contain antiseptic in the raw material master batch.
The present invention realizes that the method for purpose is to account for the nylon 1010 salt of overall weight 93.89-98.97%; add the antiseptic that accounts for overall weight 1-6% again; after being mixed; vacuum sucks in the polymeric kettle; add the inferior acetic acid that accounts for overall weight 0.02-0.05% again; account for the phosphorous acid of overall weight 0.01-0.06%; vacuumizing vacuum is 98.7KPa; charge into carbon dioxide 49.05KPa then; temperature is raised to 220 ℃; the still internal pressure is 1.177MPa, keeps venting after 1 hour, dewatering time 1-1.5 hour; normal pressure emptying 1 hour again when pressure reduces to zero; charge into discharging behind the carbon dioxide 931KPa again, again through the cold rinse bank casting; raw material of anti-bacteria nylon is made in the comminutor pelletizing after the drying.Described antiseptic is a sulfate, aluminum sulfate, zinc oxide, cupric oxide, alum, aluminium oxide, zinc sulfate.
Advantage of the present invention is: antiseptic can be evenly distributed in the nylon 1010 raw material, delivery of antimicrobials is evenly lasting, it is moderate that antiseptic and nylon are formed proportioning, do not influence the original physical performance of nylon, the product made from this nylon raw material that contains antiseptic has the effect of killing various assorted bacterium attached to it.And human body is free from side effects.Have wide range of applications, method is simple and practical.
Below in conjunction with embodiment method of the present invention is further described.
The selected antiseptic of the present invention is a sulfate, aluminum sulfate, zinc oxide, cupric oxide, alum, aluminium oxide, zinc sulfate are the product of selling on the market, be the powder shape, above-mentioned raw materials can be ground into the particle powder of particle diameter 0.5-1 micron, can in above-mentioned antiseptic, choose wantonly several.The glacial acetic acid that the present invention adds is the conditioning agent of molecular weight, and phosphorous acid adds as stabilizing agent.Machinery involved in the present invention, the product that is on the market to be sold as cold rinse bank, comminutor.
Embodiment 1:
Get the nylon 1010 salt that accounts for overall weight 93.89% and add zinc oxide and 3% (weight) zinc sulfate that accounts for overall weight 3%; after mixing; vacuum sucks in the polymeric kettle; in still, add the inferior acetic acid that accounts for overall weight 0.05% again; account for the phosphorous acid of overall weight 0.06%; vacuumized about 10 minutes; its vacuum is 98.7KPa; abundant then carbon dioxide 49.05KPa is raised to 220 ℃ with temperature, and the still internal pressure is 1.177MPa; keep venting after 1 hour; dewatering time 1-1.5 hour, normal pressure emptying 1 hour again when pressure reduces to zero, charge into carbon dioxide 981KPa again after; discharging; through the cold rinse bank casting, use the comminutor pelletizing again, make nylon raw material master batch of the present invention after the drying.
Embodiment 2:
Pulverulent nylon 1010 salt accounts for overall weight 98%; add again and account for the aluminum sulfate of overall weight 1% and 0.97% zinc oxide; after being mixed; vacuum sucks in the polymeric kettle; add inferior acetic acid again and account for 0.02% of overall weight, phosphorous acid accounts for 0.01% of overall weight, and vacuumizing vacuum is 98.7KPa; charge into carbon dioxide 49.05KPa then; be warmed up to 220 ℃, the still internal pressure is 1.177MPa, keeps venting after 1 hour; dewatering time is about 1 hour; emptying was 1 hour when pressure was zero, charged into discharging behind the carbon dioxide 981KPa again, again through the cold rinse bank casting; the nylon antibacterial matrices is made in the comminutor pelletizing after the drying.
Embodiment 3:
Nylon 1010 salt accounts for 96% (weight), adds the antiseptic that accounts for 3.96% (weight) again, and the antiseptic total amount is decided to be 100 unit of weights, zinc oxide accounts for 30 unit of weights, aluminum sulfate accounts for 30 unit of weights, and alum accounts for 25 unit of weights, and zinc sulfate accounts for 15 unit of weights.After both were mixed, vacuum sucked in the still, adds inferior acetic acid again and accounts for 0.02% (weight), and phosphorous acid accounts for 0.02% (weight).Finish all the other by embodiment 1 described scheme again and go on foot the poly-raw material of anti-bacteria nylon of the present invention of making.
Bactericidal effect of the present invention is significant, and is as follows through testing:
(1) test strain adopts Escherichia coli ATCC25922 strain,
(2) golden yellow staphylococcus ATCC6538 strain,
(3) test material: nutrient agar, physiological saline are prepared by national requirements standard " disinfection technology standard ",
(4) bactericidal assay method: take by weighing raw material of anti-bacteria nylon 1 gram is added in the 10ml sterilization physiologic dose brine pipe, behind 121 ℃ of 20 minutes high pressure sterilizations, add 10Cfu/ml, bacterium liquid 1ml, in 20 ℃-25 ℃ effect different times, the absorption aforesaid liquid is done to pour into to cultivate and is carried out count plate, and control group carries out count plate with the identical nylon 1010 (making master batch under the same conditions with pure 1010 nylon) that does not add antiseptic with above-mentioned method, calculates sterilizing rate.
(5) bactericidal assay results strain title effect killing rate % contrast in 7 hours bacterium liquid (cfu/ml) Escherichia coli 99.90 1.1 * 10
6Golden yellow 99.86 6 * 10
6Aureus strains title effect killing rate % contrast in 20 hours bacterium liquid (cfu/ml) Escherichia coli 99.99 5 * 10
6Golden yellow 99.94 4 * 10
