Abstract
The invention relates to a preparation method of a porous fiber non-woven fabric. The aim of the preparation method is to improve the product performance of the conventional non-woven fabric, so that the non-woven fabric meets the requirements on high-precision and high-performance filter. The technical scheme is that the preparation method of the porous fiber non-woven fabric comprises the following steps in sequence: (1) uniformly mixing a polymer and a diluent to obtain a blend with 10 to 60 percent of polymer; (2) melting and extruding the blend in the step (1) by adopting a screw extruder granulator, and directly cooling and granulating in air; (3) producing master batches in the step (2) by melt-down equipment to obtain a primary non-woven fabric; (4) extracting to remove the diluent from the primary non-woven fabric in the step (3), performing pore-forming on fibers in the non-woven fabric, and drying to obtain the porous fiber non-wave fabric; (5) recovering mixed waste liquid of the diluent and an extraction agent for reuse.
Description
Technical field
The invention belongs to fabrics for industrial use field, be specifically related to one by Thermal inactive hole creating technology with molten
Spray technique combines the method preparing porous fibre non-woven fabrics, prepared non-woven fabrics can be used for environmental protection, water processes,
Air filtration etc..
Background technology
Melt blown technology is dependent at a high speed, high temperature gas flow (very close to melting point polymer) winding-up polymer melt makes it obtain
Prepare a kind of method of superfine fibre to stretching rapidly, can one step forming be non-woven fabrics.Pass through melt blown technology
The non-woven fabrics being assembled into by fiber amorphous packings produced, has the most excellent structural property, as fiber surpasses
Carefully, specific surface area is big, porosity is high, pore space structure is mutually communicated, solutes accumulation resistance is little, the suitableeest
Share work adsorb and filter separation material.Melt spraying non-woven fabrics product defends protection (haze, bird flu, air doctor
Purify), thermal, absorbing sound and lowering noise, the field such as sewage disposal (municipal wastewater, crude oil pollution adsorb) have
Unique advantage.Melt blown technology technological process is short, and production efficiency is high, and the yearly productive capacity of a production line is
Hundred tons to kiloton rank.Due to high content of technology, market prospect is big, and its level of development has become as measurement one
One of important symbol of individual country textile industry comprehensive strength.But, existing melt blown technology still suffers from some not
In place of foot: the processing highly energy-consuming of pure melt, die head and hot air temperature often require more than 260 DEG C, and this can make again
Become depolymerization problem；Pure melt viscosity is big, extrusion difficulty；Master batch fluidity of molten is required higher,
The melt-blown PP Pipe Compound of high fusion index need to be used, as required to use the melt index polypropylene more than 800g/10min female
Grain, its need to by degraded conventional polypropylene or with metallocene catalysis produce obtain, price compares conventional polypropylene
Master batch expensive more than 50%.
Existing melt spraying non-woven fabrics product still cannot meet high accuracy and high-performance filtration requirement, as haze mask,
Automobile/tank engine is dust-proof, as to improve its product using effect or performance further, increased it
Specific surface area, this by fibre diameter is reduced to nanoscale and can introduce two kinds of approach realizations of loose structure.
Nonwoven Technologies company uses the spinneret orifice of a diameter of 63.5 μm, is prepared for fibre diameter big
Being about the polypropylene fibre of 500nm, but the method yields poorly, spinneret price is abnormal expensive simultaneously, also
Easily cracking and plug, production cost is the highest.The most domestic melt-blowing equipment and pp material all cannot be expired
The working condition of foot nanofiber.The introducing of loose structure can be by adding not phase in meltblown polymer master batch
The inorganic nano-particle held or polymer, then dissolved by solvent or the method calcined carrys out selective removal
Pore-forming, but the method can cause fibre machinery performance to be greatly reduced and there is the incomplete problem of dissolving.
Thermal inactive technology (thermally induced phase separation is called for short TIPS) is to send out in recent years
A kind of polymer forming hole method that generated is ripe.In 1980, Castro etc. first proposed TIPS and prepares micropore
The method of film, and apply for United States Patent (USP) US Patent424798.TIPS ultimate principle is as follows: non-for many
Polarity or low pole thermoplastic crystalline's high polymer, at normal temperatures with some high boiling little molecular fluid (diluent)
Immiscible, but (the generally greater than fusing point of crystalline high polymer) can form homogeneous phase solution at elevated temperature, reduces
Decline due to solvability after temperature and the induction of polymer crystallization factor produces liquid-liquid (L-L) or solid-liquid (S-L) phase
Separating, then remove diluent with extractant, mixture Central Plains diluent is taken up space and is become hole, finally
Form coherent microcellular structure.TIPS method only has heat exchanging process, without regard to complicated mass exchange mistake
Journey, therefore has the advantages such as simple to operate, influence factor is few, membrane porosity is high simultaneously, be not easily formed defect,
Good mechanical property, pore size, distribution, controlled porosity.
