Background technology
Along with the aggravation of environmental pollution, the various materials for gas filtration get more and more, and the ambient pressure thus brought also is increasing year by year.At present, from personal protection mask, filtering material for air purifying, to industrial dust removal bag and production line environment cleaning equipment filter material, it mostly is the micrometer fibers filtering material goods that non-degradable plastics are raw material such as polyethylene, polypropylene and Merlon, it is not good at if these disposable products process, it is possible to cause " white pollution " of a new round.
Poly butylene succinate has raw material as the industrial macromolecular material with complete biodegradable function and is easy to get, and cost is low, it is easy to the advantages such as biodegradation, and is widely used in the industry such as degradable cutlery box, degradable medical apparatus.Use the PBS plastic bag manufactured three months in general soil can be degradable, it can be used as raw material prepare nano-fiber material and be applied to field of Environment Protection and have broad prospects and huge social benefit.
Melting electrostatic spinning technology is the nano-fiber material preparation method grown up on the basis of electrostatic spinning technique in recent years, compared with electrostatic spinning technique, organic solvent is not used due to it, it is not related to recycling and the purification environmental-protection problem of a large amount of organic solvent, there is the advantages such as cost is low, productivity is high, energy-saving and cost-reducing.
Nano-fiber material prepared by melting electrostatic spinning technology is utilized to have homogeneity good, porosity is high, can directly obtain the advantages such as required nanofiber filtration material without base material, is applied to gas filtering material and has the clear superiority that vapour lock is little, filter efficiency high tradition is not available for micron filtration material.
Summary of the invention
Poly butylene succinate macromolecular material is combined by the present invention with melting electrostatic spinning technology, prepare the nano-fiber material of brand-new tool complete biodegradable unique advantage, and be applied to gas filtering material and prepare personal protection mask and air purifier.
The invention belongs to nanofiber and manufacture field, particularly to a kind of method preparing nanofiber filtration material for raw material with poly butylene succinate macromolecule.Concretely comprise the following steps: (1) is by poly butylene succinate heating to molten condition；(2) being extruded by screw extruder, extruder head is that micron arrives nanometer porous plate；(3) there is high voltage electric field between extruder head and reception plate, utilize electrostatic spinning technique to prepare nanofiber gas filtering material；(5) haze mask or air purifier are prepared using this material as filtering material.
Further, the melt temperature described in step (1) is at 110-250 DEG C.The number in the hole of the porous plate described in step (2) is 300-1000, and bore dia is 50 nanometers-20 microns.Extruder head and the high voltage electric field received between plate described in step (3) are 5 kilovolts to 200,000 volts, and extruder head and the distance received between plate are 1-100 centimetre.
Further, nanofiber filtration material of the present invention serves many purposes, the above-mentioned nanofiber filtration material preparation method according to mask and program can be processed into mask, this mask can be used in haze, anti-dust, under exceedingly odious weather condition, bad working environments when and wear when common protection.
Further, it is also possible to described nanofiber filtration material is processed into given size, for the filter element of air-conditioning or air purifier, or the filter element as air-conditioning or air purifier, or as making the material of haze screen window.
Usual melting electrostatic spinning technology is based on solution electrostatic spinning technique and develops.Compared with solution electrostatic spinning technique, the yield of melting electrostatic spinning technology of the present invention is higher and can solve the harm that in solution electrostatic spinning process, environment is caused by solvent volatilization.In melting electrostatic spinning process, melt by, after extruder head, moving to reception plate under the traction of high voltage electric field.Improving temperature makes melt viscosity reduce, and under identical voltage, the reduction (temperature rising) of melt viscosity, fibre diameter reduces.When melt viscosity is fixing, improves voltage and can effectively increase the pull strength of melt jet, then reduce fibre diameter, otherwise, fibre diameter increases.Meanwhile, when temperature and voltages keep constant, melt viscosity and fibre diameter are had a direct impact by the molecular weight of melt, improving the molecular weight of melt, the winding power between molecular melt chain strengthens, thus causing melt viscosity to increase and fibre diameter increase, otherwise, fibre diameter reduces.
The present invention is compared with conventional melt spinning, add high voltage electric field assembly, by high-tension electricity field force by spinning attenuation, the fiber prepared than traditional spining technology more carefully can reach nanometer scale, prepared fibrous material has higher porosity and specific surface area, has higher filter efficiency and less vapour lock as micro-nano granules filtering material.If under same filter efficiency, it is possible to saving raw materials for production, material therefor is the 10%-50% of conventional filter material.
Additionally, present invention employs biodegradable polymer succinic acid-butanediol ester (Poly (butylenesuccinate)), being commonly abbreviated as PBS, its molecular formula is HO-(CO-(CH2)2-CO-O-(CH2)4-O)n-H is a kind of biodegradable polymers synthesized by succinic acid (succinicacid) and BDO (butanediol), has cheap, and heat resistance and mechanical property are good, and the advantage such as processing characteristics excellence.Easily by the enzyme decomposition in the multiple-microorganism of nature or animal and plant body, metabolism, first microorganism corrodes the surface of polyester, then by the enzyme of microorganism secretion the ester bond in polyester being had an effect makes it be hydrolyzed, it is finally decomposed to carbon dioxide and water, is the polyester plastics of biological degradability that typically can be degradable.
