Background technology

The present invention relates to high performance geosynthetic article, for example the cellular confinement system (cellular confinement system) of reinforcing band, enhancing element, reinforcing membrane, especially dimensional stability.The invention particularly relates to such geosynthetic article, this geosynthetic article is characterised in that to have and is suitable for providing the structure and the composition of strengthening the property, and its polymer composition by increase-volume forms or comprise the polymer composition of increase-volume.

Plastics geotechniques strengthens loading capacity, stability and the erosion resistance that element and goods (especially cellular confinement system (CCS)) are used to improve geotechnological strongthener (hereinafter referred to as GRM), described geotechnological strongthener for example for the soil, rock, sand, stone, mud coal, clay, the concrete that support by CCS, gather materials, road-making material and native prepared material.

CCS is mainly made by the band that comprises high density polyethylene(HDPE) (HDPE) or medium-density polyethylene (MDPE), and it is characterized in that having cellular three-dimensional lattice cell structure.When being filled with geotechnological material, this structure (comprises, for example, soil, rock, sand, stone, mud coal, clay, concrete, gather materials, the mixture of road-making material and other native prepared materials or these materials and/or other materials (as be included in this material fluid)) time, this structure all provides enhancement and stabilization to geotechnological material and surrounding structure.

Since between the hoop tensile strength of lattice locular wall, the adjacent lattice chamber by the rubbing effect between dynamic resistance and CCS and the GRM, the result, CCS strengthens GRM by shearing resistance and the rigidity that improves GRM.Under loading condiction, CCS produces strong side direction reinforcement edge and soil-Ge locular wall frictional force.These mechanism produce the bridging structure with high flexural strength and rigidity.This bridging structure can improve the deformation performance of conventional granular packing material under the long-term load condition, and makes the thickness of structural support elements and weight reduce significantly to reach 50%.CCS can be used for bearing load and uses (for example making subgrade stability), can be used for the intermodal transportation place, can be used for rail under so that retaining wall is stablized, be can be used for to ballast aggregate protecting GRM or vegetation, and can be used for ramp and pipeline.

Term " HDPE " is meant hereinafter and it is characterized in that density is 0.941g/cm ³Arrive 0.960g/cm at least ³Polyvinyl resin, term " MDPE " is meant and it is characterized in that density is 0.926g/cm ³To 0.940g/cm ³Polyvinyl resin.

Enhancement type CCS is a composite structure, and wherein GRM is compressed and compacting towards the CCS wall, and like this, the frictional force between wall and the GRM makes structure be kept perfectly.Plastics lattice chamber and GRM weighting material dynamically support each other, and should be able to withstand wide in range load, vibration, impact load, thermal stresses and corrosive nature.

Three principal elements that influence the permanently effective weather resistance of GRM-CCS composite structure are: the creep resistance of (1) plastic material; (2) frictional force between lattice locular wall and the geotechnological strongthener (GRM) (it is stabilized in CCS and strengthens); And the dimensional stability of (3) CCS and the GRM that is compacted.

The creep meeting of CCS wall causes the loss that the frictional force of CCS-GRM composite structure becomes absent-mindedness and causes structure function.HDPE and other polyolefine can not be resisted creep, be higher than about 35 to 40 degrees centigrade (℃) temperature under especially like this.The situation of use MDPE even even worse.

The possibility of Earthwork Products (especially CCS) heating is relevant with tellurian tropical area usually.As used herein, in one embodiment, term " tropical area " is meant the area that is positioned within terrestrial equator both sides (north side or southern side) latitude 42 degree.In one embodiment, " tropical area " is meant the area that is positioned within terrestrial equator both sides latitude 30 degree.Particularly, tropical area comprises along desert belt or the zone within desert belt.For example north African, Spain south, the Middle East, Arizona State, Texas, Louisiana, Florida State, cen.am., Brazil, India, SOUTHERN CHINA, Australia and a Japanese part can be considered to tropical area.Generally speaking, this tropical area regularly stands to be higher than 35 ℃ or even be higher than 40 ℃ temperature.The be exposed to the sun surface of the plastics under direct sunlight can reach 75 ℃ even the temperature up to 90 ℃.

CCS at high temperature Failure Mechanism may be complicated.The first step is the CCS surface heating (the especially heating by absorbing sunlight) of GRM surface and exposure.The rising of CCS temperature can cause dimensional change, and this is because polyethylene (PE) has high thermal expansivity (CTE)---about 150/1000000ths to 200//1000000th ℃ of temperature variation (ppm/ ℃), and CTE itself can increase along with the rising of temperature.This means that when being increased to 65 ℃ the CCS of 100 meters (m) can increase about 60 centimetres to 80 centimetres (cm) on its length by 25 ℃.Because the expansion that the GRM that is kept by CCS takes place is much smaller, so deterioration takes place in the keying action between GRM and the CCS (being the ability that CCS keeps GRM).In addition, under the situation of CCS heated for several every day hour, this being heated can cause creep and irreversible expansion.The result is, even when temperature reduces, the tight contact action between CCS and the GRM also can irreversibly reduce, thereby the integrity of composite structure and performance can reduce, or even forfeiture.Therefore, the stretching, extension of the GRM structure (being limited by CCS before it) that is expanded, caused thus by heating, CCS or the recirculation of subsiding and being formed can cause the ultimate failure of CCS function or obviously forfeiture.

When in the fall with the process (a kind of GRM that causes is with respect to CCS expansible process) of winter GRM experience water freezing and thawing, this situation becomes even worse.Because the creep resistance of HDPE and MDPE is medium and even lower, so the result can make the contact action between CCS wall and the GRM further lose.This process is abiogenous, a kind of like this process for example takes place, wherein in winter, because circulation freezing and that thaw takes place, perhaps (for example) has the concrete of crackle or the water freezing in the rock, makes building stones be pushed away unearthed earth, thereby causes concrete or rock failure.

The shear surface (being generally the wall of each lattice chamber) of CCS structure can be pressed decorative pattern, or provide other to strengthen the measure of frictional force, so that increase the frictional force between CCS and the GRM and prevent that the lattice locular wall from deforming, thereby make the integrity of composite structure not be destroyed.

The commercially available CCS based on HDPE that gets is characterised in that: it has medium rigidity, medium dimensional stability and acceptable creep resistance under about-10 ° to+40 ℃ temperature range.Yet the feature of these CCS also is to exist following defective: they have medium tenacity, high CTE, high creep tendency (is especially like this more than 40 ℃ the time in temperature), and they have chemosensitivity to hydrocarbon (more specifically say so fuel and oil).

For wherein CCS or film will contact fuel and oily application, chemosensitivity to hydrocarbon is disadvantageous, described application examples is as being, CCS or film are used as the GRM reinforce or are used to reinforce in landfill yard, oil field, service station, intensive parking lot and chemical plant, or are used as the blocking layer at landfill yard and reservoir.

Limited mechanical property and the chemical property of HDPE and MDPE (certainly also have other polyolefine) especially can be related to creep resistance and limited thermotolerance and the high expansion tendency when being exposed to hydrocarbon fluid.If under identical load, with (as a side is polymeric amide or polyester between the engineering thermoplasties (" ET "), the opposing party is a urethane) creep resistance and the chemical resistance of hydrocarbon fluid compared, then up to now, engineering thermoplastic resin has higher dimensional stability and rigidity, have significantly lower creep tendency, fuel and organic liquid are had obviously higher chemical resistance, and have higher intensity.

Form with ET and correlatedly to be, polyethylene has better tear strength and puncture resistance than the engineering thermoplasties, be lower than under the temperature of zero degrees celsius especially like this.Tear strength and anti-to pierce through power be important factor in film and CCS, in the CCS of perforation even more important, its middle punch can provide the passage that passes plastic wall, but can weaken band and increase its susceptibility to tearing.In assembling process, tear strength and puncture resistance also are important, and wherein in described assembling process, it is empty that CCS remained before filling GRM, therefore need withstand with assembling and GRM and fill relevant human activity.

Be higher than under about 40 ℃ to 50 ℃ temperature when performance compared engineering thermoplasties's advantage even more obvious.Most of CCS make by a plurality of bands are welded, and for HDPE and MDPE, engineering thermoplasties's welding strength and formation of weld speed are more excellent.Comparing with polyolefine, because the engineering thermoplasties has higher polarity, is that the frictional coefficient of (especially and between soil and the mud coal) is improved between itself and the GRM based on another advantage of engineering thermoplasties's CCS therefore.The engineering thermoplasties has stronger resistivity to the swelling that hydrocarbon (as fuel and oil) causes.

The engineering thermoplasties as the key constraints of the alternative resin in the CCS manufacturing field is: the high elastic coefficient of influence assembling simplification, relatively higher cost, show more crisp relatively character under about 10 ℃ temperature and influence the low melt strength that band is extruded simplification to the higher relatively susceptibility of bronsted lowry acids and bases bronsted lowry, being lower than.

The technology that engineering thermoplastic resin and polyolefin resin is combined into a kind of blend is described in many pieces of prior art patent documentations to some extent.

U.S. Patent No. 3,963,799 provide the method for polymeric amide and polyolefinic composition that is generally suitable for packaging industry and the alloy (Compatibilized blends) that forms them.Because the performance that the composition of describing in this patent documentation has inherent fragility (especially at low temperatures) and lacks damp proof and anti-UV light, so it is not suitable for comprising that the structural geotechnique of CCS uses.The difficult problem of the unresolved composition welding of this patent documentation aspect, the problem of the hydrolytic instability of also unresolved polymeric amide phase (it can be at soil, hydrolysis especially takes place in acid soil).And the composition of this patent documentation has too high CTE at CCS and film.

U.S. Patent No. 4,564,658 provide the composition that is only formed by polyester and linear low density polyethylene (LLDPE), and expanding material is not provided, and the reagent of the dispersion stableization that makes two kinds of incompatible polymers promptly is not provided.Therefore, extruding application (for example extrude and be used for the band that the geotechnique uses), melt flow instability (melt fracture), and can observe between the thing phase and separate.Because the composition of describing in this patent documentation has flexible and the creep tendency, so it is not suitable for comprising that the structural geotechnique of CCS uses.Because the inherent nature of LLDPE, the composition of this patent documentation has too high CTE at CCS and film.

This patent documentation does not provide yet and prevent that blend from the solution of hydrolysis taking place in soil and landfill yard, oil and hydrocarbon, and prevents that blend is owing to the solution of being heated and the UV light action is degraded.This patent documentation is not discussed welding quality yet.

U.S. Patent No. 5,280,066 provides the composition that is formed by polyester, polyolefine and functionalized styrene based elastomers that is used to improve shock resistance (in particular for injection molding).This invention only limits to polypropylene (PP) as the polyolefine part.PP is being lower than under about 0 ℃ temperature too firmly, and lacks flexible (and CCS must possess this performance).The composition of this patent documentation has too high CTE at CCS and film.

The expanding material of this patent documentation is the styrenic material, so it has limited anti-UV optical property, thereby makes said composition be confined to indoor application or the usage period is about 1 to 2 year open air application.Polyester blend (especially not carrying out the polyester blend of stabilizing treatment at hydrolysis specially) may will lose efficacy in relatively short for some time in soil (especially pH is greater than those soil of 7).This patent documentation does not provide the abundant protection at oil and fuel, bronsted lowry acids and bases bronsted lowry and UV light.It does not discuss welding quality yet.

U.S. Patent No. 6,875,520 provide the composition that is formed by polyamide block copolymer and utmost point softish polyolefine.This invention can be used for flexible geotechnological film, but is not useable for comprising that the structural geotechnique of CCS and high performance thin film uses.Become shortcoming for the high flexibility of advantage in CCS in the geotechnological film of flexibility: when applying load on the CCS of support GRM, the composite structure that is formed by above-mentioned two kinds of components interacts as integrated system and load.CCS by and provide rubbing effect between the GRM of rigidity and hardness to load to transmit between each lattice chamber.If CCS is too soft, load can cause that CCS deforms until its rubbing effect reduction with GRM.Under this particular state, integrated system can be irreversibly impaired, and no longer can provide the weather resistance, rigidity of expectation and to the static stabilization of GRM.This patent documentation does not provide the solution that occurs hydrolysis problem at said composition in soil and landfill yard, or the solution of hydrolysis problem occurs at it when being exposed to concrete or be characterised in that during pH is greater than other media of 7.The composition of this patent documentation has too high CTE for CCS and film.

Required UV of CCS and thermostability are also discussed or do not provide to this patent documentation, especially at UV and the thermostability of 2 years or longer prolonged period.

Therefore the long-term and urgent demand that has the polymer composition (especially comparing improved polymer composition with MDPE) that improvement is provided with HDPE, described polymer composition is characterised in that the performance with improvement, as in the following performance one or more: the creep resistance that has raising in wide in range temperature range (as-70 ℃ to+90 ℃ temperature range); Strength and stiffness are higher; Have lower CTE, and at high temperature the impaired proneness of rigidity is lower; GRM freezing/thaw/have higher creep resistance in the process of heating, more can resist the swelling that causes by the low molecular weight material such as oil and hydrocarbon, to about 100 years period, all had higher photodegradation of anti-UV and heat-resisting degradation property in about 2 years under the wide in range weather condition (from the arid to the severe cold), and welding strength and weld seam withstand load performance (load bearing resistance) with improvement.The polymer composition of this improvement is favourable for CCS that is used for performance application and the enhancement type GRM that comprises oil, bronsted lowry acids and bases bronsted lowry, aggressiveness chemical, solvent and fuel.In addition, need the Earthwork Products (for example geotechnological film and geo-grid) of improvement, this Earthwork Products has the vital performance of improving for the application of having adopted these goods.Be not met yet up to now to these compositions with by the demand of its material that makes.

In one embodiment, Earthwork Products that is formed by compatibilizing polymer composition of the present invention or the Earthwork Products that comprises compatibilizing polymer composition of the present invention have such welding property, wherein welding line can bear the load that applies continuously for many years with solder joint (for example need not into the discrete weld seam of line) above under 40 ℃ the temperature, in one embodiment, this temperature is about 40 ℃ to about 70 ℃, in another embodiment, this temperature is about 40 ℃ to about 60 ℃.In one embodiment, Earthwork Products that is formed by compatibilizing polymer composition of the present invention or the Earthwork Products that comprises compatibilizing polymer composition of the present invention can withstand such temperature and reach at least 2 years to about 100 years.In such embodiment, described Earthwork Products is able to take such temperature and reaches the time of such length and can not disintegrate or take place tangible creep.Forming correlated with the present invention is that the geosynthetic article that is made by prior art material (for example HDPE or MDPE) can not stand the time that such temperature reaches such length at all.In one or more such embodiments, the performance that described Earthwork Products provides is considerably beyond the performance such as prior art materials such as HDPE or MDPE.

Known because polyethylene has low density, low modulus and low-friction coefficient, and be difficult to by ultrasonic welding it be welded.The new combination of ET and PO is compared with HDPE and has been produced the welding property of improving.The welding property of disclosed improvement is that the performance of above qualification combines and the result that produces among the present invention.The welding property of improving is the most remarkable in ultrasonic welding.Therefore, during ultrasonic welding, high frequency (for example ultra sonic machinery vibration) is delivered on the plastic components that matches by ultrasonic bonding machine.On point of contact, junction or the interface of two parts, applied force and the surface friction that is produced by ultrasonic vibration and/or the combination of intermolecular friction elevate the temperature, till the fluxing point that reaches thermoplastics.Then remove ultrasonic energy, thereby between two plastic components, produce molecule combination or welding.High frictional coefficient and high acoustical conductivity are favourable.

More effective in the material that supersonic welding is connected on relative rigidity and the relative unbodied material.

Ultrasonic welding system comprises high frequency electric source usually, it typically is 20kHz to 40kHz.High-frequency energy is introduced in the horn (being also referred to as soldering tip), by them mechanical vibration is sent on the target to be welded.

Unexpectedly, when the method that is limited according to the present invention during with ET and PO (comprising expanding material) blend, especially when Compatibilized blends also comprises filler, its welding property with respect to having similar size but unfilled band and unfilled PO-ET blend based on HDPE all significantly improve.Improve the speed of speed that part is melt surface, its intensity of surface recovery, final welding strength and the performance of anti-long-term load at high temperature thereof.

A kind of like this mechanism is proposed, this mechanism is interpreted as collaborative welding property following in unrestriced mode: comparatively inflexible is rich in the ET phase and (is characterized as and has high Young's modulus and low acoustic damping, be creep modulus, out-of-phase modulus and dissipation factor) can respond ultrasonic vibration and will the more low-melting PO of being rich in heat phase fast, so the weld seam of weld seam when forming speed than independent welded H DPE to form speed faster.In these polymer phases (particularly being rich in the ET phase), there are Young's modulus, frictional coefficient that filler can increase this phase and this velocity of sound in mutually.In cooling step subsequently, being rich in ET, to compare the crystallization rate that is rich in the PO phase faster, thereby the cycle is shortened.In cooling step, filler plays the effect of nucleator.The filler (especially submicron particles and nano-scale particle) that exists can improve ET and PO nucleation rate mutually, make with respect to unfilled HDPE or MDPE or for the PO-ET blend of not increase-volume, it is firm and durable that the weld seam that is produced becomes, and speed is obviously faster.
