Description
Technical field
The invention belongs to non-woven fabrics manufacturing fields, and in particular to a kind of nonwoven composite earthwork cloth 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.The application of geosynthetics originates from twentieth century 50
Age, domestic geotextiles are one of the Eighth Five-Year Plans of country, and China promulgated that " geosynthetics is chopped fiber needle-punched in 1998
Non-woven geotextile " (GB/T17638-1998) standard, geotextiles are widely applied in multiple fields at present.
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 nonwoven composite earthwork cloth.
Another object of the present invention is to provide the preparation methods of above-mentioned nonwoven composite earthwork cloth.
Technical solution: in order to achieve the above object of the invention, what the present invention was specifically performed by: a kind of nonwoven composite earth
Work cloth, the component including following parts by weight: 40 ~ 50 parts of acrylic resin, 30 ~ 40 parts of polypropylene fibre, 5 ~ 10 parts of plasticizer
With 1 ~ 5 part of heat stabilizer.
Wherein, the plasticizer DEHP.
Wherein, the heat stabilizer is zinc stearate.
A kind of preparation method of nonwoven composite earthwork cloth, comprising the following steps:
(1) each raw material is added in reciprocating mixing extruder and carries out heating mixing, control 160 ~ 180 DEG C of heating temperature, be kneaded 2
~ 4 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 100 ~ 120 DEG C of temperature；
(3) mixed material after high pressure squeezes out forms fiber subsequently into spinning equipment by filter impurity screening；
(4) 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 is compared with traditional technology, light weight and cost is low, it is corrosion-resistant, have anti-filter, draining, every
From, enhancing etc. excellent performances, be widely used in the earthwork engineerings such as water conservancy, electric power, mine, highway and railway.
