The antibacterial active carbon fiber is a polyester fiber adsorption material; a carbon and metal composite material coating is deposited on the surface of the porous polyester fiber material. The preparation process of the antibacterial active carbon fiber comprises the following steps: firstly, causing nitrogen to enter the free volume of the polyester fibers by an over-saturation foaming method; and then causing the nitrogen pressed into the free volume to expand through pressure reduction and temperature rise treatment to form lots of bubbles and fixing the shape of holes. The carbon and metal mixed target is deposited on the surface of the fiber material by a magnetron sputtering method.
Description
Technical field
The invention belongs to antibacterial environment protection field, particularly a kind of cost is low, adsorptivity is high and have carbon fiber and the manufacture method thereof of antibiotic resistance to mould activity.
Background technology
Active carbon (GAC) is a kind of porous charcoal through activation processing, has extremely strong adsorption capacity, the existing century-old history of its application in fields such as military affairs, chemical industry, environmental protection.Activated carbon fiber (being fibrous), is covered with micropore on fiber, it is higher several times to tens times in air than granular activated carbon to organic gas adsorption capacity, high 5～6 times in the aqueous solution, fast 100～1000 times of the rate of adsorption.In industrial his the superpower adsorption capacity of utilizing, remove to reclaim organic solvent, purify air, purify water.
Activated carbon fiber is a kind of high-tech product, only have in the world a few countries to produce, his goods can be the forms such as silk, paper, felt, cloth, traditional activated carbon fiber because of complex process and energy consumption height long in time limit, the market price is in 250,000/ton left and right, be tens times to twenties times of active carbon, seriously limited its market use amount.
And due to activated carbon fiber in use, also can adsorb microorganism, filtering adsorbing material is gone mouldy, can cause microbial contamination.
In order to overcome above-mentioned defect, the invention discloses a kind of manufacturing process simple, cost is low, has again antibiotic resistance to mould activated carbon fiber.This high-specific surface area, high added value, high-tech, oligosaprobic novel active material with carbon element have fabulous development prospect and wide application market.
Summary of the invention
Technical problem to be solved by this invention is: in prior art, in use, because easy generation of existence of microorganism gone mouldy, and the processing cost of active-carbon fibre material is too high for activated carbon fiber.
For solving this technical problem, the invention provides a kind of novel active carbon fibrous absorption material, be a kind of polyester fiber absorption filtering material, this porous polyester fibrous material surface deposition has the composite coating of carbon and metal.In composite coating, material with carbon element comprises graphite, carbon dust, and metal material comprises one or more in copper, silver, zinc, titanium, manganese, nickel, aluminium.
The present invention also provides a kind of preparation method of above-mentioned polyester fiber absorption filtering material, first adopt over-saturation foaming to prepare porous polyester fibrous material, by physical gas-phase deposite method, at porous polyester fiber surface, prepare the composite coating of one deck carbon and metal, this technique can complete in same equipment again.
Over-saturation foaming is prepared porous polyester fibrous material, and concrete operations are,
(1) utilize room temperature pressurization, under High Pressure, make gas fully infiltrate polyester fiber, gas is entered in the free volume of polyester fiber,
Macromolecular fibre kind is numerous, it is perforate base material that polyester fiber (as PET, PBT, PAR, TPEE etc.) is take in the present invention, preferred PET fiber wherein, PET itself is nontoxic, tasteless, and security is good, has good mechanical property, high temperature resistant, cryogenic property, oil, fat, alkali, olefin(e) acid and most of solvent are had to good patience, and transparency is high, there is uvioresistant ability;
Perforate gas has nitrogen, argon gas, carbon dioxide or uses two or more mists, preferred nitrogen of the present invention, and nitrogen thermodynamics, chemical property are all more stable, and nonhazardous effect, cost are low, free from environmental pollution,
In this step, high voltage control is at 6MPa-8MPa, and different pressure is different on the impact of the void density in porous fibre: pressure is larger, and fiber bubble density is larger, but simultaneously higher to requirements such as working condition, equipment,
Pressing time is also influential to bubble density, and the time of pressurization is longer, and the hole in the fiber obtaining is more, and power consumption also will be more, and general control was at 4 hours to 24 hours;
(2) rapid depressurization is to normal pressure, and then is down to negative pressure, wherein, the time from high pressure drop to " a negative atmospheric pressure ", be controlled in 10min, 7-10min is comparatively suitable;
(3) in coiling constant temperature oven, negative pressure (a negative atmospheric pressure) foaming, constant temperature oven temperature is 120 ℃-160 ℃, and foamed time is 10S-20S, and step (2), (3) can be carried out in same equipment,
Different blowing temperatures are influential to porous fibre hole density, and temperature is higher, and gas expansion is faster, and the hole density in polyester fiber also presents positive correlation and improves,
Step-down and hyperthermic treatment, make to be pressed into the gas expansion in free volume, forms a large amount of bubbles, and in Polyester Fibers fixing hole shape,
To sum up, by the foam process that then heats up with room temperature pressurization, can make foamed fibre, bubble structure is with the difference for the treatment of conditions, and is very different.In the situation that other process conditions are constant, in foamed fibre, bubble density increases along with the increase of pressure, pressing time, blowing temperature, foamed time respectively, and wherein foamed time is greater than after 10s, and bubble density is had no significant effect.
After tap operation finishes, by physical gas-phase deposite method, prepare being operating as of composite coating, adopt vacuum coating equipment, with magnetically controlled sputter method, the composite target material of carbon and metal is deposited in the top layer and hole of porous polyester fiber, concrete technology step is: (1) porous fibre is dry to be processed; (2) upper stove; (3) inflatable body; (4) plated film; (5) lower stove,
In step (3), plated film adopts magnetic-control sputtering coiling machine, and institute's inflatable body is methane, acetylene or both mists, and in step (4), volumetric flow of gas is 400～600SCCM, electric current: 6A～15A.
The composite target material of carbon and metal is the compressing hybrid target of material with carbon element and metal material, and preparation technology is: by material with carbon element and metal powder, after mixing in proportion, with cold static pressure technology, be pressed into bulk, and excision forming then, pressure is every square centimeter of 50-80 kilogram.The percentage by weight of carbon and metal be " 99.9% to 0.01% " to " 80% to 20% ", metal is selected from one or more in copper, silver, zinc, titanium, manganese, nickel, aluminium.
Beneficial effect of the present invention is: (1), when preparing porous polyester fibrous material, adopts nitrogen gas foaming, low without any toxic action and cost to people and animals, free from environmental pollution; (2) on porous polyester fiber, composite target material enters into hole by activated carbon loaded, has greatly increased the specific area of activated carbon, has strengthened its suction-operated; (3) Nanometer Copper is mixed in carbon dust, can make the composite obtaining there is long-acting antibiotic, mildew-resistant effect; (4) use the method for magnetron sputtering, the composite deposit of deposit carbon and metal, has reduced environmental pollution, has reduced production cost.
