Technical field
The present invention relates to functional chemical fibre manufacturing technology, be specially a kind of method of producing skin-core structural micro-wave screening functional fibre by melt direct spinning, belong to chemical fiber field.
Background technology
At present, the kind of domestic functional fiber and the mode of production thereof have a lot, sum up to get up to comprise: production technology is spun in the twin-screw section; Island composite algorithm production technology etc.Though these methods also can production performance functional fibre preferably, all have weak point.Twin-screw method and island composite algorithm production procedure are long, complex procedures, and technique controlling difficulty is big, and the product physical and chemical performance is inhomogeneous.
Summary of the invention
At the deficiencies in the prior art, the technical problem that quasi-solution of the present invention is determined has provided a kind of manufacture method of new micro-wave screening functional fibre.
The objective of the invention is to design a kind of functional fiber with skin-core structure, core-skin weight percentages prescription is: core component 75～85%, skin component 15～25%.The percentage by weight prescription of its cortex material is: cortex polymer 75～85%, electrical-conductive nanometer powder 5～8%, microwave absorption 4～7%, bulking agent 3～9%, coupling agent 0.2～4%; Its core layer material is 100% polymer.
The object of the present invention is achieved like this:
1, makes cortex material: after by the prescription of described cortex material cortex polymer, conductive powder, microwave absorption, bulking agent and coupling agent evenly being mixed, under 180～290 ℃ of temperature, squeeze through twin-screw and to obtain the cortex material melt.
2, above-mentioned cortex melt is injected composite component by the method for frequency conversion metering; Another melt inlet of composite component directly is connected with the measuring pump of melt Direct Spinning.
3, compounding flux sprays from the spinnerets of composite component, and melt spins that spinning is carried out in production procedure, reeling makes the micro-wave screening functional fibre of skin-core structure of the present invention routinely then.
The polymer of cortex of the present invention and sandwich layer should be similar polymers, includes but not limited to high polymers such as PET, PBT, PTT.
Conduction powder of the present invention is one or more in carbon black, nickel powder, copper powder, cobalt powder, the aluminium powder etc.The good carbon black of the conduction preferred electric conductivity of powder, and surface of carbon black is through handling.
Microwave absorption of the present invention is one or more in tri-iron tetroxide, chromium ferrite, barium ferrite, the ferronickel boron.
Bulking agent of the present invention is three different stearic phthalidyl ferrous acid isopropyl esters, three (DBSA base) ferrous acid isopropyl ester, three (two hot phosphorus phthalein oxygen bases) ferrous acid isopropyl ester, one or both in three (the burnt phosphorus phthalein of dioctyl oxygen base) ferrous acid isopropyl ester, stearic acid, zinc stearate, the Tissuemat E.
Coupling agent of the present invention is a kind of in γ-glycidoxypropyltrimewasxysilane, γ-metering system phthalein oxygen base trimethoxy silane, N-β-(amino-ethyl)-gamma-amino propyl trimethoxy silicane, the γ-An Jibingjisanyiyangjiguiwan.
It is the following fine particle of 45nm that conductive powder of the present invention, microwave absorption all should be processed into particle diameter.
Micro-wave screening functional fibre of the present invention is owing to adopted core-sheath composite structure, in fact its core-skin layer is equivalent to section and spins functional fibre, and its sandwich layer is because of being identical with the most component of cortex, thereby can solve qualitative compatibling problem, lamination can not occur.Simultaneously, make, can also solve the not wide old trouble of other composite spinning method technology fine setting property by the multiple unit tube structural reform.
The present invention uses conventional equipment, and technology is simple, and processing ease is with low cost, is convenient to industrialization promotion and uses.
The specific embodiment
Below provide 1 specific embodiment of the present invention:
6 parts of barium ferrite magnetic powders, the average grain diameter of getting 76 parts of the PET sections of melt index 50,5 parts in copper powder material, γ-4 parts of metering system phthalein oxygen base trimethoxy silanes, average grain diameter that average grain diameter is 40nm and be 38nm be 9 parts of three (DBSA base) ferrous acid isopropyl esters of 1 μ m after fully mixing, under 190 ℃, extrude and produce the fibrocortex melt through twin-screw; Skin, core volume ratio by fiber is that 2: 8 usefulness fused mass directly spinning modes of production are produced the micro-wave screening PET long filament with core-sheath composite structure then.
After measured, the microwave reflection attenuation rate of gained fiber is 10db, and x alpha ray shield rate can reach 79%.
