Abstract
The invention relates to a processing method of a novel environment-friendly geocomposite drainage mat. The novel environment-friendly geocomposite drainage mat is prepared by taking geotechnical cloth as a raw material and PLA (poly lactic acid) as an auxiliary material through the steps of heating, fusing, extruding, wiredrawing and forming, cooking and packaging. The method provided by the invention is refined in process, simple and convenient to implement, economic and environment-friendly, and industrial production is easy to realize; under a certain time and temperature condition, the mat is capable of naturally decomposing into carbon dioxide and water within one to two years, the pressure resistance of a product is 250-1,000Kpa, the product is large in porosity and easy to drain, and the water can be drained and a foundation also can be consolidated.
Description
Technical field
The present invention relates to a kind of processing method of novel environment friendly soil engineering drainage straw mats.
Background technology
At present, for fear of the saturated sliding problem that produces that absorbs water because of soil cover, water draining mat is usually arranged in the area soft in soils such as civil buildings, but present existing water draining mat processed complex, production cost is high and be difficult for to decompose, easily to the soil reclamation secondary pollution.
Summary of the invention
The present invention provides a kind of processing methods easy, large, the degradable novel environment friendly soil engineering drainage of product porosity straw mats of processing in order to overcome the above problems.
Technical scheme of the present invention is: with raw material geotextiles and auxiliary material PLA through heating, melting, extrude, wire-drawing shape, cooling packing form.
Described heating, melting process carry out six times altogether, in turn heating, and temperature raises gradually, and the temperature of six heating is respectively 170-220 ℃, 180-220 ℃, 200-250 ℃, 220-260 ℃, 230-260 ℃, 260-280 ℃.
Each composition of described PLA and shared hundred parts of ratios of quality thereof are classified as: PLA 60%～70%, terephthalic acid (TPA) 10%～30%, plasticizer 1%～5%, inorganic filler 5%～10%, defoamer 0.1%～0.3%, polyethylene 0～3%.
Described plasticizer is any one in epoxidized soybean oil or the glycerine.
Described inorganic filler is any one in talcum powder or the kaolin.
Technique refining of the present invention, be easy to implement, economic environmental protection, be easy to suitability for industrialized production, under the regular hour temperature conditions, but become carbon dioxide and water one to natural decomposition in two years, the high 250-1000Kpa of the compression strength of product, product porosity of the present invention is large, is easy to draining, can draining again can consolidated subsoil.
The specific embodiment
The processing method of novel environment friendly soil engineering drainage straw mats, with raw material geotextiles and auxiliary material PLA through heating, melting, extrude, wire-drawing shape, cooling packing forms, described heating, melting process carries out six times altogether, in turn heating, and temperature raises gradually, the temperature of six heating is respectively 170-220 ℃, 180-220 ℃, 200-250 ℃, 220-260 ℃, 230-260 ℃, 260-280 ℃, each composition of described PLA and shared hundred parts of ratios of quality thereof are classified as: PLA 60%～70%, terephthalic acid (TPA) 10%～30%, plasticizer 1%～5%, inorganic filler 5%～10%, defoamer 0.1%～0.3%, polyethylene 0～3%, described plasticizer is any one in epoxidized soybean oil or the glycerine, and described inorganic filler is any one in talcum powder or the kaolin.
