Description
Technical field
The present invention relates to building material field, particularly to a kind of geotextiles.
Background technology
Geotextiles is a kind of New Building Materials, and it is present in soil and pipeline, the one between gabion, or retaining wall
In order to strengthen water sport and to hinder the geosynthetics of soil movement.As interlayer material, geotextiles need high temperature resistant, have
The feature that higher melt, tensile strength are high, uniformity is good, adsorptivity permeability chemistry strong, anti-biological resistance is strong.
Conventional geotextiles has excellent filtration, isolation, reinforcement protection effect in use, and tensile strength is high, anti-freezing
The feature of excellent effect.But routine geotextiles the most usually there is also some problems, in engineering, geotextiles is general
Can be permanently present, but it mostly is macromolecular material, so aging phenomenon easily occurs.Aging phenomenon is very big to the harm of engineering,
There will be the problems such as pit, cracking, rut, antiskid performance is not enough during pavement usage, and solve these problems and be accomplished by road pavement
Keep in repair, thus economic loss can be brought.
Summary of the invention
The deficiency existed for prior art, it is an object of the invention to provide the geotextiles of a kind of function admirable, this soil
Work cloth is anti-aging and anti-freezing excellent effect, high temperature resistant, tensile strength is high, good penetrability.
The above-mentioned technical purpose of the present invention has the technical scheme that a kind of geotextiles, including as follows
The component of parts by weight,
By above-mentioned setting, select meta-aromatic polyamide as the base material of geotextiles, be because meta-aromatic and gather
Acid amides is originally as linear macromolecule, in flexible structure, steady chemical structure.Meta-aromatic polyamide has the high temperature resistant of excellence
Property, flame resistance, dimensionally stable under high temperature, wearability, resistance to bend(ing) is good, so being capable of withstanding high temperature as geotextiles when it uses,
And it is not susceptible to deformation.
Polyacrylonitrile-based carbon fibre, it is to general organic solvent, and acid, alkali all has good corrosion resistance, and superelevation is strong
Power, insoluble the most swollen, the little light weight of density, fiber finer and soft, wear-resisting endurance, there is lubricity, Bc is good.So
It plays numerous excellent effect in the geotextiles being processed into.And polypropylene machine carbon fiber and meta-aromatic polyamide phase
Can improve the mechanical property of meta-aromatic polyamide during effect so that the flexibility of meta-aromatic polyamide, resistance to bend(ing) adds
By force, it is not susceptible to fold.
And the jute-kenaf fibres in component has compared with high-tenacity, fiber is thick and stiff, the thick thick geotextiles that is suitable for weaving, also have
Fabulous water imbibition, environmental sound, cheap.So component adds jute-kenaf fibres, it is possible to make geotextiles have very
Good adsorptivity.
Also include antioxidant, owing to material can occur oxidation under long-term use, and by external condition
Affect and accelerated oxidation, so the use of antioxidant can slow down oxidation rate, the service life of auxetic material.
In component, the addition of light stabilizer can shield light, absorbs and shifts light energy, so just can slow down and execute
Man-hour, geotextiles was exposed to the impact that causes under light.And light stabilizer and antioxidant synergy can reduce oxidant
Consumption and strengthen aging-resistant effect.
In component, the use of cold-resistant agent can make material also maintain excellent mechanical property under compared with low temperature, it is ensured that normal
Work.
In component, the existence of nano silicon can improve bonding effect, and it can improve the toughness of material, tension
Intensity and impact strength also improve, and heat resistance also increases substantially, moreover it is possible to improve the ageing resistace of material.
