Abstract
The utility model discloses a waterproof needled felt, including the base cloth layer, the complex is in fibrous layer about the base cloth layer, and bond the waterproof layer in the fibrous layer outside, the fibrous layer is the fibre web layer by alumina silicate fibre and glass fiber intermeshing formation, the waterproof layer is in with the coating by adhesion layer the last polytetrafluoroethylene tectorial membrane of adhesion layer is constituteed, adhesion layer bonds the outside of fibrous layer. The utility model discloses an acupuncture felt comprises base cloth layer, fibrous layer and waterproof layer, and the waterproof layer in the outside can improve the water -proof effects of acupuncture felt, and inboard base cloth layer and fibrous layer can not be corroded, the life of improvement acupuncture felt, fibrous layer inboard simultaneously is the fibre web layer by alumina silicate fibre and glass fiber intermeshing formation, not only can improve the intensity of acupuncture felt, still is used for the transition layer into base cloth layer and waterproof layer, makes the filter effect of acupuncture felt not receive the influence on the tectorial membrane layer in the outside.
Description
Technical field
The utility model relates to a kind of Nomex, specifically a kind of waterproof Nomex.
Background technology
Nomex in current art is mainly used in filtering material, forms fiberglass needled mat with fiberglas chopped strand acupuncture after comb and parallel cotton fibers prior to spinning on fiberglass-based cloth; Or for heat preserving and insulating material; And cut Nomex for strengthen the glass of thermoplastic sheets short. At present, have at some that corrosive liquid or gas, filtrating smoke dust temperature are higher, the occasion of smoke components more complicated, usually use some filtering materials, the temperature of particulate matter is higher, and there is bigger corrosion, the thermostability of filter felt, chemical resistance and filtering accuracy thereof are required higher.
Summary of the invention
Goal of the invention: the utility model object is for the deficiencies in the prior art, it is provided that a kind of waterproof Nomex, waterproof, anticorrosion effect are good, and do not affect the filter effect of Nomex.
Technical scheme: waterproof Nomex described in the utility model, comprise base cloth layer, it is compounded in the layer of fibers that described base cloth layer is upper and lower, and it is bonded in the waterproof layer outside described layer of fibers, described layer of fibers is the web layer mutually tangled formed by aluminium silicate fiber peacekeeping glass fibre, described waterproof layer is made up of adhering layer and the tetrafluoroethylene overlay film being coated on described adhering layer, and described adhering layer is bonded in the outside of described layer of fibers.
The utility model further preferably technical scheme be that described base cloth layer is staple fibre flannelette, the positive and negative two sides of staple fibre flannelette is provided with screen cloth, and described layer of fibers is compounded on described screen cloth.
Preferably, the filament strength of described staple fibre flannelette is 30 ~ 40N.
Preferably, in described layer of fibers, the density of glass fibre is 2 ~ 3g/cm3��
Preferably, the thickness of described layer of fibers is 5 ~ 10mm.
Preferably, described layer of fibers mesosilicic acid aluminum fiber and the glass fibre aperture of web layer formed of mutually tangling is 10 ~ 30 ��m.
Useful effect: Nomex of the present utility model is made up of base cloth layer, layer of fibers and waterproof layer, outermost waterproof layer can improve the waterproof effect of Nomex, and the base cloth layer of inner side and layer of fibers can not be corroded, it is to increase the work-ing life of Nomex; The layer of fibers of inner side is the web layer mutually tangled formed by aluminium silicate fiber peacekeeping glass fibre simultaneously, it is possible not only to the intensity improving Nomex, the transition layer being also used as base cloth layer and waterproof layer, the filter effect making Nomex is by the impact of coating layer in outside.
Accompanying drawing explanation
Fig. 1 is the structural representation of waterproof Nomex described in the utility model.
Embodiment
Below by accompanying drawing, technical solutions of the utility model are described in detail, but protection scope of the present invention is not limited to described embodiment.
Embodiment:A kind of waterproof Nomex, comprises base cloth layer 1, is compounded in the layer of fibers 2 of base cloth layer about 1, and be bonded in the waterproof layer 3 outside layer of fibers, as shown in Figure 1:
Base cloth layer 1 is staple fibre flannelette, and the positive and negative two sides of staple fibre flannelette is provided with screen cloth, and the filament strength of staple fibre flannelette is 30 ~ 40N.
Layer of fibers 2 is the thickness formed that mutually tangles by aluminium silicate fiber peacekeeping glass fibre is the web layer of 5 ~ 10mm, and the aperture of web layer is 10 ~ 30 ��m, and web layer is compounded on the screen cloth of base cloth layer 1, and the density of glass fibre is 2 ~ 3g/cm3��
Waterproof layer 3 is made up of adhering layer 31 and the tetrafluoroethylene overlay film 32 being coated on adhering layer 31, and adhering layer 31 is bonded in the outside of layer of fibers 2.
Although as mentioned above, it is necessary, represented and described the technical scheme of the present invention with reference to specific preferred embodiment, but it shall not be construed as the restriction to the present invention self. Under the spirit and scope of the present invention prerequisite not departing from claims definition, it can be made various change in the form and details.
