Abstract
The preparation process of tea polyphenol-base monofilament for air filter net includes the steps of stoving material, compounding material, stirring, smelting and extrusion, cooling, drafting and setting. Powdered tea polyphenol-based material extracted from tea and with powerful bacteriostasis and antibiosis functions in certain amount is added into polypropylene or polyethylene resin master batch, the mixture is produced into tea polyphenol-based plastic monofilament, and the monofilament is further woven into air filter net for air conditioner, air freshener and other air filtering product for improving air quality. The preparation process is easy to be applied in industrial production.
Description
The present invention relates to a kind of preparation technology of monofilament for tea polyphenol base air filter net; be that the extremely strong powdery tea-polyphenol base material antibacterial, antibacterial functions that has that will extract from tealeaves mixes in polypropylene plastics masterbatch resin or the vinyon masterbatch resin by a certain percentage; make monofilament for tea polyphenol base air filter net by the plastic extruder molten spinning; this monofilament has antibacterial, antibacterial functions equally, is a kind of advanced composite material (ACM).Airstrainer be can be woven into this monofilament, air-conditioner, air cleaner are applied in or all can carry out in the airfiltering product.
In recent years along with the raising of social life level, people are to the air-conditioner of a large amount of uses, the air quality pay attention to day by day of air cleaner output, airstrainer in requirement air-conditioner, the air freshener is except can filtering out airborne dust, also can suppress or kill harmful germs such as airborne mould, virus, make the with fresh air of output be of value to healthy more, just require to be used to weave the monofilament that airstrainer uses and have antibacterial, antibiotic performance.
Existing antibiotic monofilament obtains by two kinds of methods: a kind of is by immersion, and methods such as brushing coat one deck chemistry anti-biotic material on the plastic monofilament surface; A kind of is that melt-spinning obtained antibiotic monofilament after chemical anti-biotic material was mixed the plastic resin master batch.The shortcoming of first method is: during the braiding screen pack, monofilament surface is rubbed, and the anti-biotic material that makes a part originally be coated on monofilament surface peels off, and has reduced the monofilament anti-microbial property; Because chemical anti-biotic material is coated on monofilament surface, not water-fast washing, service life is short.The shortcoming of second method is: use be chemical anti-biotic material, have the trace excitant; Antibiotic kind is less; Peculiar smell can't destroy foul odors.
Tea Polyphenols be in the tealeaves based on the polyphenol compound of catechin, be active component important in the tealeaves.For many years, the Tea Polyphenols that studies show that in a large number both domestic and external all has excellent antibacterial activity to causing tens kinds of sick bacteriums of people, the broad-spectrum antibacterial property that has shown Tea Polyphenols has extremely strong inhibition ability to Pseudomonas aeruginosa, Escherichia coli, staphylococcus, bacillus especially.Just because of Tea Polyphenols has many unique functions such as anti-oxidant, antibiotic, antiviral, people study to have grasped and extract the technology that Tea Polyphenols is made pulverulent material from tealeaves in recent years, thereby utilize the tea-polyphenol base material development to develop numerous products and be applied in fields such as food, medicine, health products and cosmetics, and also do not relate in field of air filtration.
The objective of the invention is: the air filtration product scope is introduced in the application of Tea Polyphenols; exactly powdery tea-polyphenol base material is mixed in polypropylene plastics masterbatch resin or the vinyon masterbatch resin; improve existing monofilament fabricating technology; get access to a kind of plastic monofilament with Tea Polyphenols composition, this monofilament has antibacterial, antibiotic performance.Be woven into airstrainer with such monofilament, pack into air-conditioner or all can be carried out in the airfiltering product.
The useful effect that the present invention has is: antibacterial, antibiotic powdery tea-polyphenol base material fully mixes makes monofilament in the plastics, monofilament antibacterial, antibacterial action is long creep rupture life; Promote the function of airstrainer, except absorption dust, strengthened the restraining and sterilizing bacteria deodorization functions of screen pack, and enlarged antibacterial range, improved quality of air environment; The natural materials of Tea Polyphenols for refining from tealeaves do not need chemical synthesis, the excitant and the contaminative that do not have chemicals to have.
Technological process of the present invention is: (1) baking material, and (2) batching, stir (3), and (4) melt extrude, (5) cooling, (6) drawing-off, (7) typing.
Be embodiments of the invention below:
1, baking material
Spinning grade polypropylene plastic resin master batch (be called for short PP) or vinyon masterbatch resin (being called for short PE) are put into dryer dry, baking material temperature is 50 ℃～100 ℃.
2, batching
Requirement to the powdery tea-polyphenol base material itself that participates in batching is: the Tea Polyphenols active quantities greater than 25%, fineness of powder is greater than 200 orders.
Powdery tea-polyphenol base material and PP or PE are prepared burden by weight proportion, and powdery tea-polyphenol base material weight is 2%～5% of PP or a PE weight, requires and powdery tea-polyphenol base material itself contains how much selecting of Tea Polyphenols active ingredient according to antibiotic degree.
3, stir
Prepared mixture fully stirs in mixer by weight proportion.
4, melt extrude
Well-beaten batching is put into plastic extruder melt extrude monofilament after by preheating, fusing, plasticizing, metering, spray wire process, melt extruding temperature is 150 ℃～320 ℃.
5, cooling
The monofilament that will melt extrude is put into tank and is cooled off, and chilling temperature is 25 ℃～45 ℃.
6, drawing-off
Cooled monofilament is put into drawing machine carry out drawing-off, drawing temperature is that 90 ℃～120 ℃, drafting multiple are 5.0～6.5 times.
7, typing
The monofilament of drawing-off is put into setting machine finalize the design, setting temperature is that 90 ℃～120 ℃, relaxation shrinkage are 3%～8%.
After implementing above-mentioned technological process, the monofilament for tea polyphenol base air filter net that can obtain the present invention relates to.Average diameter is that the comprehensive physical property of the polypropylene monofilament of 0.2mm is: ultimate strength 〉=850CN, elongation at break 18%～50%.
China is Tea Production big country, and the technology of extracting Tea Polyphenols and make powdery tea-polyphenol base material from tealeaves reaches its maturity.And utilize powdery tea-polyphenol base material to make the tea-polyphenol base plastic monofilament by the present invention, be woven into airstrainer again, air-conditioner, air freshener or all of packing into can be carried out in the airfiltering product, not only improved human lives's air quality, what be beneficial to man is healthy, also opened up new approach, turned waste into wealth for the utilization of a large amount of low-grade teas of China, tea dust.
