The invention discloses a kind of geotextiles, the component including following parts by weight: 40 ~ 50 parts of close silicate fiber, 40 ~ 50 parts of hydrophilic polyester, 5 ~ 10 parts of carbon fiber and 1 ~ 5 part of antiager.Meanwhile the invention also discloses the preparation methods of above-mentioned geotextiles.The present invention has excellent skid resistance, flexibility and waterproofness, is suitble to the construction of infrastructure in all kinds of productions compared with traditional technology.
Description
Technical field
The invention belongs to non-woven fabrics manufacturing fields, and in particular to a kind of geotextiles and preparation method thereof.
Background technique
Geotextiles have outstanding filtering, draining, isolation, reinforcement, protective action, with light-weight, tensile strength is high, seeps
Permeability is good, high temperature resistant, anti-freezing, ageing-resistant, corrosion resistant characteristic, is mainly used in water conservancy harbour, navigation channel, railway, highway etc.
The big engineering of the small stress of silt diameter.The application of geosynthetics originates from nineteen fifties, domestic geotextiles
It is one of the Eighth Five-Year Plan of country.
Summary of the invention
Goal of the invention: in view of the above-mentioned deficiencies in the prior art, it is an object of the present invention to provide a kind of geotextiles.
Another object of the present invention is to provide the preparation methods of above-mentioned geotextiles.
Technical solution: in order to achieve the above object of the invention, what the present invention was specifically performed by: a kind of geotextiles, packet
Include the component of following parts by weight: 40 ~ 50 parts of close silicate fiber, 40 ~ 50 parts of hydrophilic polyester, 5 ~ 10 parts of carbon fiber
With 1 ~ 5 part of antiager.
A kind of preparation method of geotextiles, comprising the following steps:
(1) each raw material is added in reciprocating mixing extruder and carries out heating mixing, control 200 ~ 220 DEG C of heating temperature, be kneaded 4
~ 8 hours；
(2) mixed material after mixing is entered after squeezing out in reciprocating mixing extruder to single screw extrusion machine and carries out high pressure height
Warm extrusion goes out, and controls 150 ~ 180 DEG C of temperature；
(3) mixed material after high pressure squeezes out forms fiber subsequently into spinning equipment by filter impurity screening；
(4) fiber of generation is cut, controls every fibre length and is no more than 150mm,
(5) fiber is subjected to woven fabric by weaving loom, is packed and stored after finally shaping.
The utility model has the advantages that the present invention compared with traditional technology, has excellent skid resistance, flexibility and waterproofness, it is suitble to each
The construction of infrastructure in class production.
