Description
Technical field
The present invention relates to field of textiles more particularly to a kind of additives for producing melt spraying non-woven fabrics, correspondingly, further relate to this
The application method of additive.
Background technology
SARS (SARS) and the type A avian influenza of 2009 (H5N1) of 2003 is lived through, melt spraying non-woven fabrics are because have
Good strainability, is used widely in disposable breathing mask and is recognized by most people.In recent years, melt spraying non-woven fabrics
Because of its good strainability, popularization energetically is not only obtained in the application of mask, but also in industrial (such as automobile, oil, sky
Tune, protective garment etc.), medical (such as operation dress), hygienic (the leakproof edge of such as baby diaper), life (such as air filtration, water
Filtering etc.) in be also widely used.With the improvement of people ' s living standards and prevent pollution realize continuous reinforcement, one
Secondary property medical treatment, the use of amenities are more and more common, and people are also higher and higher to the filtering accuracy of air and water.It is in this way, molten
The product consumption that blown non-woven fabric or melt spraying non-woven fabrics are combined with other non-woven fabrics increasingly rises, and produces the raw material of melt spraying non-woven fabrics
Demand also increasingly increases.Because of the particularity of melt spraying non-woven fabrics production technology, for producing the molten of the raw material of melt spraying non-woven fabrics
It is very high to melt index (MFR) requirement, generally requires MFR in more than 800g/10min.Thus the production to melt-blown raw material is brought
Bigger difficulty.
Before 10 years, the production for being meltblown raw material is all the method using monomer polymerization, i.e., adds in propylene list in a kettle
Then body adds in the polypropylene original that catalyst, antioxidant and peroxide etc. obtain MFR higher by polymerisation
Material.In the past 10 years, people are in order to save cost, simple flow, many people by using the polypropylene of low melt index as raw material,
The melt-blown raw material of high MFR is produced by the method for secondary response.
A kind of ultra-fine melt spraying non-woven fabrics mixing material, its melt-blown prepared as disclosed in 101665993 B of Chinese patent CN
Non-woven fabrics and its manufacturing method, by polypropylene I that melt index is 150~400g/10min and melt index be 1200~
The polypropylene II mixing of 1600g/10min, polypropylene I and polypropylene II are 10: 90~90 by weight：After 10 mixing, carry out
It is granulated.By the particulate material that above-mentioned granulation obtains after extruder heating melting, runner is distributed by the spinneret on die head through melt
Hole squeezes out, and surpasses a times drawing-off through thermal current, and the fiber cooling and solidifying of fine is deposited on collecting net equipment, winding networking to get to
Melt spraying non-woven fabrics.
A kind of for another example polypropylene mixtures of 102675732 B of Chinese patent CN and its preparation method and application, homopolymerization is gathered
Propylene, two benzal sorbic alcohols, thio-2 acid two (18) ester, calcium stearate, antioxidant are added in storage bin, after being stirred
It is added in double screw extruder, and adds in di-tert-butyl hydrogen peroxide thereto, then, squeezed what is obtained in double screw extruder
Go out product to be cooled down, be granulated, screening obtains polypropylene mixture, then heated and melted with the polypropylene mixture, and spinneret is made
Melt spraying non-woven fabrics.
Above two technical solution is all using the polypropylene of low melt index as raw material, is carried out by addition additive secondary
Reaction, re-melts, the polypropylene miser of high fusion index is made in pelletizing, then polypropylene miser is heated and is melted, through mould
Head sprays, and cools and solidifies and melt spraying non-woven fabrics are made.
The method that either polypropylene of monomer polymerization or low melt index adds in additive is first made poly- the third of high MFR
Alkene raw material, then melt spraying non-woven fabrics are prepared with the polypropylene of high MFR, all it is that production procedure is long, working hour is long, of high cost, is unfavorable for
Improve the efficiency of production.For this purpose, it is urgent to provide new technical solutions to solve above-mentioned existing technical problem.

Specific embodiment
To make the object, technical solutions and advantages of the present invention clearer, present invention work is further retouched in detail below
It states.
Melt spraying non-woven fabrics are that the polypropylene of high fusion index is used to distribute runner through melt after extruder heating melting
It is squeezed out by the spinneret orifice on die head, surpasses a times drawing-off through thermal current, the fiber cooling and solidifying of fine is deposited on collecting net equipment, receives
It is rolled into net and is made.Wherein, melt index (MFR) refers to a kind of numerical value for representing mobility when plastic material is processed.Melting
Exponential quantity is bigger, represents that the processing fluidity of the plastic material is better, on the contrary then poorer.The polypropylene price of high fusion index is held high
Expensive, preparation process is complicated, but its heating has good mobility and ductility, is very suitable for the system of melt spraying non-woven fabrics
It is standby；And the polypropylene of low melt index is cheap, derives from a wealth of sources, but poor fluidity during its processing, is not suitable for preparing melt-blown nothing
Woven fabric.For this purpose, how the polypropylene of low melt index is converted to the polypropylene of high fusion index by those skilled in the art's research
Mixture.
In the present invention, the polypropylene of high fusion index refers to that melt index is more than the polypropylene of 800g/10min, eutectic
The polypropylene for melting index refers to that melt index is less than the polypropylene of 800g/10min；The melt index refer to 230 DEG C,
Under 2.16kg pressure, the melt index that is measured according to the method for GB/T 3682-2000.
At present, the research emphasis in melt spraying non-woven fabrics field and direction are to make the polypropylene of low melt index by adding auxiliary agent
It is prepared into the polypropylene mixture of high fusion index, then the polypropylene mixture melting extrusion melt-blown nonwoven by high fusion index
Cloth.But time-consuming for such production method, and energy consumption is big, and flow is complicated, and production and transportation are of high cost, for this purpose, the present invention changes now
There is the point of penetration of research direction, no longer prepare the polypropylene mixture of high fusion index as intermediate product, but pass through eutectic
Melt spraying non-woven fabrics can directly be produced by melting the polypropylene addition additive of the present invention of index, simplified production procedure, reduced production
Cost is conducive to the development of melt spraying non-woven fabrics industry.

It closes：
CxHyOz……Ⅱ
In II formulas, it be the range of 13~53, z is 2~6 that the range of x, which is the range of 6~26, y,.
Wherein, the carbochain of the fatty acid amide and dual-tert-butyl peroxide is any alkane, alkene, alkynes or benzene
The structure of ring, x, y and z value change dependent on saturation degree.Also, carbochain can have appropriate alkyl substitution and bifurcated.
In the production process for preparing melt spraying non-woven fabrics, the polypropylene of additive of the present invention and low melt index is abundant
Mixing, adds in into screw extruder together.Melt stage, dual-tert-butyl peroxide and low melt are heated in screw extruder
The polypropylene of index chemically reacts, and the polyacrylic strand of low melt index is cut off, and molecular weight becomes smaller, so as to make to melt
The mobility of body improves, and achievees the purpose that improve melt index.And fatty acid amide has the function of lubrication so that polypropylene melt
Body preferably drawing-off under high temperature and high speed hot-air, it is raw under the synergistic effect of fatty acid amide and dual-tert-butyl peroxide
The melt spraying non-woven fabrics that output is come show the performances such as good ultimate strength, bursting strength and hydrostatic pressing, with directly with high melting means
