Description
Technical field
The present invention relates to the manufacture method of a kind of non-woven fabrics, be specifically related to the manufacture method of a kind of shield type anti-radiation composite non-woven fabric.
Background technology
Electromagnetic radiation be one cannot see, impalpable pollution, be called " stealthy killer " by people. Most of household electrical appliance such as television set that people touch in daily life, microwave oven, and radar system, broadcast singal receive-transmit system, radio frequency and microwave medical equipment, communication launches the station etc. and can produce the electromagnetic radiation of various forms, different frequency, varying strength. Research finds, electromagnetic radiation pollution is the main inducing of cardiovascular disease, diabetes, cancer sudden change, and also human reproductive system, nervous system and immune system can be caused direct injury, in addition electromagnetic radiation be cause anemia of pregnant woman to miscarry, the risk factor of the pathological changes such as sterile, monster, excessive electromagnetic radiation also can cause child's tissue development, skeleton development, visual deterioration, the function reduction such as liver hemopoietic, severe patient may result in retina shedding, and also may result in male's sexual decline, female endocrinic disorders and menoxenia.
In order to control the harm that electromagnetic radiation brings, scientists has done various trial, creates multiple radiation proof material, can be generally divided into absorption-type radiation proof material and the big class of shield type radiation proof material two. Absorption-type radiation proof material is to form one between radiation source and human body to have the barrier that can sponge major part electromagnetic radiation, and shield type radiation proof material is dependent on the characteristic of shielding material and forms a barrier between radiation source and human body, reduce the harm of major part electromagnetic radiation, and wear a kind of method that the clothing that various radiation-proof fabric makes are simple and effective radiation-screenings.
The patent disclosure such as CN1245839, CN1274774, CN101275329, CN1778551, CN1690274, CN101660241 and CN102634931 a series of radioprotective textiles and manufacture method thereof, its manufacture method is broadly divided into two kinds, and one is metal blending or adds wire netting (such as stainless steel cloth);Two is add screener (such as tungsten, bismuth, bismuth oxide, barium sulfate, ferroso-ferric oxide etc.), the former is that blending or shuffling enter tinsel or metallic fiber in textile, this manufacturing approach craft brief introduction, effect is obvious, but this series products often quality is endured with all one's will abundant, in wearability difference and manufacture process, two kinds of fibers are difficult to mix homogeneously, and shielding electromagnetic waves performance is not ideal enough, even also have most advanced and sophisticated static electricity gathered and thorn people's phenomenon produces. Screener is attached to fiber or weaving face fabric surface by plating or chemical plating by the latter, and its protected effect is good, and gained fabric is light and thin, and wearability is better, but feel is still harder; And fabric durability is poor, repeatedly easily causes coating after friction and come off from web surface thus affecting shield effectiveness.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, it is provided that a kind of manufacture method that can shield major part shielding electromagnetic waves type anti-radiation composite non-woven fabric, adopt the non-woven fabrics that the method prepares, adhesion effect is good, and wearability is good, long service life.
For achieving the above object, the present invention is achieved through the following technical solutions:
A kind of manufacture method of shield type anti-radiation composite non-woven fabric, including following manufacturing step:
1) by a certain amount of macromolecule beads fuse, after spinneret sprays, utilize air-flow or machinery to become net, obtain melted non-woven fabrics;
2) surface of melted non-woven fabrics obtained in step 1), is uniformly adhered to last layer screener or shielding glue, is then passed through heat treatment and obtains described shield type anti-radiation composite non-woven fabric by the mode of spray webbing or blade coating.
In preferably: described step 2), the melted non-woven fabrics being coated with shielding glue obtains described shield type anti-radiation composite non-woven fabric with primarily efficient filter wool pressurization compound, sizing.
Preferably: the macromolecule pellet described in step 1) is one or more in polypropylene, polyester, viscose rayon, polyethylene and polrvinyl chloride.
Preferably: described screener is the mixture of boehmite and zeolite powder.
Preferably: the mass ratio of described boehmite and zeolite powder is: (20%��40%): (80%��60%).
Preferably: by weight percentage, the consumption of described screener is the 40��60% of macromolecule pellet consumption.
Preferably: described shielding glue is mixed by boehmite, zeolite powder, titanate esters modifying agent, hydroxylated cellulose, methyl gluceth and deionized water and stirring.
Preferably: the mass ratio of described boehmite, zeolite powder, titanate esters modifying agent, hydroxylated cellulose, methyl gluceth and deionized water is 1:(3��5): (0.3��0.8): (0.3��0.8): (0.02��0.05): (10��15).
Preferably: by weight percentage, the consumption of described shielding glue is the 40��60% of macromolecule pellet consumption, and the coating thickness of described shielding glue is 0.05��0.1mm.
Preferably: the median of described boehmite is 1 ��m��4 ��m, and described zeolite powder is 4A zeolite powder.
The beneficial effects of the present invention is, the main material of fabric is non-woven fabrics, and quality is frivolous, pliability good, soft handle; Do not use tinsel or metallic fiber, do not rely on reflection or refraction mechanism shielding electromagnetic wave; The non-woven fabrics of the present invention uses the boehmite mixture with zeolite powder as screener, it is possible to the electromagnetic radiation of shielding major part admirably, eliminates overwhelming majority electromagnetic pollution; Owing in manufacture process, screener have passed through surface hydrophilic modification, add the adhesion of itself and fiber, the Effect on Mechanical Properties of fiber is little, it is easy to weaving. Be can be used for the manufacture of Radiation proof dress, protective cover etc. by the non-woven fabrics of the method manufacture of the present invention, be applied to national defence, scientific research, industrial and mining establishment, health care and huge numbers of families.
