Abstract
The invention relates to high-intensity polypropylene geotechnical cloth which comprises a singeing layer, wherein a non-woven cloth layer is arranged on the lower surface of the singeing layer; a water-repellency layer is arranged on the lower surface of the non-woven cloth layer; a finishing layer is arranged on the lower surface of the water-repellency layer; the singeing layer, the non-woven cloth layer, the water-repellency layer and the finishing layer are tightly combined. The high-intensity polypropylene geotechnical cloth is high in quality, long in service life, higher in intensity, higher in ductility, acid-proof, alkaline-proof and anti-corrosion.
Description
Technical field
The present invention relates to a kind of geotextiles, be specifically related to a kind of pp geo textiles.
Background technology
At present, the braided geotextile on market is various, but most of geotextiles layer of structure is all more single, can not meet the long-time requirement that continues use, in actual use, easily occurs a lot of problems.The geotextiles intensity of use is lower now, elongation per unit length is lower, acid-fast alkali-proof corrosive nature is poor, can not meet the engineerings such as short silt corral, harbour, harbour, airport, dock, Waterway Regulation of reclaiming fields from the sea and make the requirement of soft raft, sand washing band, and, the production technology of common geotextiles is more general, the product quality of producing is also more general, there is no needling structure level, and entirety is unstable, so common geotextiles can not meet actual user demand.
Summary of the invention
Goal of the invention: the object of the invention is, in order to overcome deficiency of the prior art, provides a kind of high-quality, long service life, intensity is higher, and elongation per unit length is higher, the corrosion resistant high-strength pp geo textiles of acid-fast alkali-proof.
Technical scheme: in order to solve the problems of the technologies described above, the high-strength pp geo textiles of one of the present invention, it comprises the layer of singing, below the described layer of singing, be provided with nonwoven layer, below described nonwoven layer, be provided with water repellent layer, below described water repellent layer, be provided with hot light layer, between them, combine closely each other.
The width of the described layer of singing, nonwoven layer, water repellent layer and hot light layer is between 4.2-8m.
Described nonwoven layer is needling structure nonwoven layer.
The present invention, through hot light processing, is firmly secured to nonwoven surface layer by water repellent layer, and forms smooth surface, and the later stage is played and the better combination of polyurethane glue in the time that high-speed railway sliding layer is constructed.
The present invention, through singing processing, shrinks fiber suede in nonwoven layer, simultaneously by heat-setting equipment, controls the elongation rate of product within the limits prescribed.
The present invention can substitute the road slag blanket of traditional railway.
Beneficial effect: the present invention compared with prior art, its remarkable advantage is: the present invention's short silt corral that is applicable to reclaim fields from the sea, harbour, harbour, airport, dock, the engineerings such as Waterway Regulation, and can substitute the road slag blanket for traditional railway, adopt hot light layer, make smooth surface, in the time of construction in later period, better bonding surface is provided, adopt water repellent layer, can meet actual user demand, can continue for a long time to use, adopt the nonwoven layer of needling structure, can effectively improve product strength, the employing layer of singing, can reduce space, thereby reach the object of holding back material, integral product quality is higher, can acid-fast alkali-proof corrosion-resistant.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Wherein:
1, the layer of singing; 2, nonwoven layer; 3, water repellent layer; 4, hot light layer
The specific embodiment
Below in conjunction with drawings and Examples, the present invention is further illustrated.
As shown in Figure 1, the high-strength pp geo textiles of one of the present invention, it comprises the layer 1 of singing, below the described layer 1 of singing, be provided with nonwoven layer 2, below described nonwoven layer 2, be provided with water repellent layer 3, below described water repellent layer 3, be provided with hot light layer 4, between them, combine closely each other; The width of described singe layer 1, nonwoven layer 2, water repellent layer 3 and hot light layer 4 is between 4.2-8m; Described nonwoven layer 2 is needling structure nonwoven layer.The present invention, through hot light processing, is firmly secured to nonwoven surface layer by water repellent layer, and forms smooth surface, and the later stage is played and the better combination of polyurethane glue in the time that high-speed railway sliding layer is constructed.The present invention, through singing processing, shrinks fiber suede in nonwoven layer, simultaneously by heat-setting equipment, controls the elongation rate of product within the limits prescribed.The present invention's engineerings such as short silt corral, harbour, harbour, airport, dock, Waterway Regulation that are applicable to reclaim fields from the sea, and can substitute the road slag blanket for traditional railway, adopt hot light layer, make smooth surface, in the time of construction in later period, better bonding surface is provided, adopts water repellent layer, can meet actual user demand, can continue for a long time to use, the nonwoven layer that adopts needling structure, can effectively improve product strength, adopts the layer of singing, can reduce space, thereby reach the object of holding back material, integral product quality is higher, can acid-fast alkali-proof corrosion-resistant.
The invention provides a kind of thinking and method; method and the approach of this technical scheme of specific implementation are a lot; the above is only the preferred embodiment of the present invention; should be understood that; for those skilled in the art, under the premise without departing from the principles of the invention, can also make some improvements and modifications; these improvements and modifications also should be considered as protection scope of the present invention, in the present embodiment not clear and definite each ingredient all available prior art realized.
