Abstract
This invention relates to the preparation method of no-woven fabrics,the preparation method of fume filter material made of the no-woven fabrics and the production made by this method. This invention includes the addition of chopped fibre no-woven fabrics and temperature resistant strengthening materials, then the mixture is melted, compound carding, acupuncturing, cooling and pressing into the mold. This invention also includes the preparation method of the fume filter material. It includes putting the no-woven fabrics on the working platform, the temperature resistance strengthening materials are covered above the no-woven fabrics, and then the other no-woven fabrics is covered, then heating, pressing, cooling, spraying polyurethane, coving the polytetrafluoroethylene and pressing into mold. Contrasting to the existing technology, it has the merit and efficiency as fellows: the design of the technology is seasonable and simple. The strength, temperature resistance, masking and antistatic ability of the no-woven fabrics made by this way are good, the temperature, the ratio of permeability, strength, lifetime, masking and antistatic ability of the fume filter materials made by this way is improved greatly.

Fig. 2 makes the schematic diagram of the method for flue filtering material for the nonwoven fabric of producing with the present invention.
The schematic diagram of the flue filtering material that Fig. 3 makes for the present invention.
The specific embodiment:
Referring to Fig. 1, producing technology of non-woven fabrics of the present invention, at first make a kind of heatproof and strengthen nonwoven fabric: the non-woven material and the heatproof strengthening material that in container, add staple fibre by following steps, this non-woven material can be terylene or polypropylene fibre, this heatproof strengthening material can be glass fibre or metal fibre, mix the thawing of heating later, the temperature range of this moment is usually between 200～1000 ℃, can adjust according to the purposes difference, mix combing then, so that it is full and uniform, carry out acupuncture again, acupuncture can be adopted multiple mode, for example water stings, laser acupuncture or their combination, the embodiment of the invention mainly adopts laser acupuncture, the diameter of laser beam is 0.05 micron～0.5 micron, power is 800-2000 watt, irradiation through laser beam, so that the fiber molecule of nonwoven fabric inside tangles, increase the intensity of nonwoven fabric, cooling then, be compression moulding at last, wherein a kind of compression moulding is that product is pressed into 3/100～1/10 of original thickness, promptly obtain tighter nonwoven fabric, the temperature of melting of heating of this moment is used 280～1000 ℃ always, and another kind of compression moulding is that product is pressed into 2/10～3/10 of original thickness, promptly relatively loose nonwoven fabric, the temperature of melting of heating this moment is used 200～800 ℃ always.Tighter nonwoven fabric is mainly used in the requirement of strength height, the occasion that often remove contamination and handle, and relatively to be mainly used in requirement of strength lower for the nonwoven fabric of pine, and penetrating rate requires high, does not need the occasion of often removing contamination, for example during the oil smoke of filter cleaning.When heatproof strengthening material of the present invention is selected metal material, invigoration effect is arranged not only then, also have shielding and anlistatig effect.
Referring to Fig. 2, the present invention also comprises the method for making flue filtering material of aforesaid nonwoven fabric, may further comprise the steps: nonwoven fabric is placed workbench, cover one deck heatproof strengthening material above, this heatproof strengthening material can adopt a kind of in metal fibre, the glass fibre, cover layer of non-woven fabric again, the 100-1000 ℃ of rod of heating pressed, cooling then, more evenly spraying polyurethane to last layer nonwoven fabric, cover last compression moulding with polytetrafluoroethylene (PTFE).
Referring to Fig. 3, the flue filtering material that the present invention obtains at last comprises polytetrafluoroethylene (PTFE) (TPFE) filter membrane 1 and the non-woven material 2 that posts on it, non-woven material 2 is divided into three layers, two layers of nonwoven fabric 2-1 that is mixed with the heatproof strengthening material for staple fibre wherein, the intermediate layer is heatproof strengthening material (net) 2-2, heatproof strengthening material (net) 2-2 can be that glass fibre also can be a metal fibre, nonwoven fabric 2-1 can be made by aforesaid producing technology of non-woven fabrics, polytetrafluoroethylene (PTFE) filter membrane 1 in this flue filtering material has cellular hole, has heatproof, aeration is good, antiacid, alkali resistant, anti-sulphur and resistance effect, it with have the flue filtering material that non-woven material 2 that heatproof strengthens function combines, improved temperature tolerance greatly, penetrating rate, intensity and service life.When heatproof strengthening material of the present invention is selected metal material, invigoration effect is arranged not only then, also have shielding and anlistatig effect.
Simple deformation of the present invention, for example sandwich construction that also can form by heatproof strengthening material and nonwoven fabric of non-woven material 2, suchlike distortion all should be thought to fall into protection scope of the present invention.
