CN102454113A - Geotextile composite film and production process thereof - Google Patents

Abstract

The invention relates to a geotextile composite film and a production process thereof. The geotextile composite film comprises base cloth, wherein the base cloth is chopped fiber needled or spun viscose filament geotextile and a layer of PE (polyethylene) geomembrane is compounded on the geotextile. The geotextile composite film provided by the invention has high tensile resistance, tearing resistance, bursting and other physical mechanical performance indexes, and can satisfy the demands of water conservation, municipal administration, construction, traffic, subway, tunnel and other civil engineering constructions; and the geotextile composite film is prepared from a polymer material and an antioxidant is added in the production process, thus the geotextile composite film can be used in unconventional temperature environments, and is commonly used in antiseepage treatment of dikes and drainage ditches and antifouling treatment of spoil areas. In the production process provided by the invention, pre-needling, inverse needling and main needling are carried out respectively, thereby increasing the mechanical properties of the product; the production process is simple and convenient to operate.

Description

A kind of geosynthetics film and production technology thereof

Technical field

The present invention relates to a kind of civil construction project material and production technology thereof, relate in particular to a kind of geosynthetics film and production technology thereof.

Background technology

In civil engineerings such as water conservancy, municipal administration, building, traffic, subway, tunnel, often need a kind of long service life, vertical transverse strength height, impermeable; The building auxiliary material that under unconventional temperature environment, still can normally use; The antiseepage that is particularly useful for dykes and dams, escape canal is handled, and the antiseepage of spoil area is handled.

Summary of the invention

The present invention is in order to overcome the above problems geosynthetics film and the production technology thereof that a kind of non-leakage, tension, anti tear, long service life are provided.

Technical scheme of the present invention is: comprise base cloth, described base cloth is chopped fiber needle-punched or the spun-bonded continuous yarn geotextiles, compound one deck PE geomembrane on geotextiles.

A kind of production technology of geosynthetics film, processing according to the following steps:

1), raw material cotton and multiple artificial fibre are sent into bale opener mixed cotton, shredding, combing processing;

2), multiple artificial fiber mixing is processed web, be mixed with web cementation after heat bonding processing of low-melting fiber;

3), the product that obtains of step be will go up and pre-needling, purl thorn, main acupuncture carried out;

4), the product behind the composite acupuncture is examined the pin operation, inspection acupuncture quality;

5), on the geotextiles after the acupuncture compound one deck PE geomembrane, obtain finished product;

6), with the finished product combing rolling that obtains.

Physical and mechanical property indexs such as tension of the present invention, anti tear, bursting are high; Can satisfy water conservancy, municipal administration, building, traffic; Civil engineering such as subway, tunnel needs, because it selects for use in macromolecular material and the production technology and added antiaging agent, so can in unconventional temperature environment, use; The antiseepage that is usually used in dykes and dams, escape canal is handled, and the antifouling processing of spoil area.

Technology of the present invention is carried out pre-needling, purl thorn and main acupuncture respectively, has increased the mechanical property of product, and has processed easy, easy to operate.

The specific embodiment

A kind of geosynthetics film comprises base cloth, it is characterized in that: described base cloth is chopped fiber needle-punched or the spun-bonded continuous yarn geotextiles, compound one deck PE geomembrane on geotextiles, processing according to the following steps:

1), raw material cotton and multiple artificial fibre are sent into bale opener mixed cotton, shredding, combing processing;

2), multiple artificial fiber mixing is processed web, be mixed with web cementation after heat bonding processing of low-melting fiber;

3), the product that obtains of step be will go up and pre-needling, purl thorn, main acupuncture carried out;

4), the product behind the composite acupuncture is examined the pin operation, inspection acupuncture quality;

5), on the geotextiles after the acupuncture compound one deck PE geomembrane, obtain finished product;

6), with the finished product combing rolling that obtains.
