Description
The present invention relates to build, the production method of hydraulic engineering waterproof material and this waterproof material.
Waterproof material occupies very consequence in building, hydraulic engineering, along with science and technology development, the synthetic polymeric waterproofing material development is also very fast.
Traditional waterproof material is based on petroleum asphalt felt, but that this material exists low-temperature embrittleness, high temperature trickling, tensile strength is low, easily shortcoming such as aging cracking.
Producing the waterproof material that uses at present mainly is divided into: rubber modified asphalt malthoid, polymer membranes and water-repellent paint three major types.Wherein to be divided into rubber be that waterproof roll, these waterproof materials are firm to polymer membranes, softness, and elasticity is big, and bonding force is strong, and durable, weather-proof, impervious, waterproof etc. is functional.But these waterproof material surface ratios are brighter and cleaner, and roughness is low, all can not directly bonding with cement material (referring to that in the process of theing cement solidifies coiled material and cement are directly bonding).And building surface layer moisture content be when surpassing certain limit (general 9%), can not construct or have a strong impact on waterproofing quality.Simultaneously, when existing waterproof roll is applied to hydraulic engineering, smooth surface, little with soil frictional force, make the earth dam angle of resting in peace little, increase engineering cost.
The object of the present invention is to provide a kind of waterproof material and manufacture method, make this waterproof material have the surface of good roughness, can be directly bonding at its solidification process with cement material, and the contact friction force of soil is greatly less than the frictional force between soil, thereby realization easy construction, waterproof is reliable, the waterproof construction that cost is low.
First technical solution of the present invention is a kind of resin compound nonwoven cloth waterproof coiled material, this waterproof roll main water barrier adopts LLDPE, each compound one deck spun-bond process polypropylene filament nonwoven of two surfaces of main water barrier is made the enhancing rack, improve the roughness of material surface, increase elasticity and intensity.Add auxiliary agent (parts by weight) colour carbon black 0.5～1.0 in the LLDPE, dilauryl thiodipropionate 0.1～0.2 and straight chain cycloalkyl hydrocarbon 0.1～0.5.
Second production method that technical solution is a resin compound nonwoven cloth waterproof coiled material of the present invention, this waterproof roll production procedure comprises the raw material proportioning, raw material mixes, plasticizing, extrude, multiple polyethylene filament nonwoven, bonding, traction, cooling such as batches at operation, and bonding process adopts direct heat pressure adhesive, must guarantee following process conditions in process of production
1) LLDPE plasticizing extrusion temperature is 180～240 ℃,
2) pressure roller diameter 150～500mm,
3) the roller temperature is adjustable continuously, 5～75 ℃ of adjustable extents,
4) the pressure roller rotating speed is adjustable continuously, adjustable extent linear velocity 1-15m/ branch,
5) roll gap pressure 0.1～0.8MPa,
6) clearance between roll 0.1～40mm, adjustable continuously,
7) the LLDPE combined temp is 120～150 ℃,
8) before the nonwoven temperature heat pressure adhesive＜40 ℃, behind the heat pressure adhesive＜100 ℃,
9) type of cooling is an air cooling, before the relative air humidity heat pressure adhesive＜75%, and behind the heat pressure adhesive＜95%, wind speed＞6 meter/minute.
Linear low density polyethylene resin has stable chemical-resistance and anti-ozone stable, and puncture resistance, impact strength, percentage elongation, environmental stress crack resistance is all good, but polyethylene oxidative degradation very slowly can take place at normal temperatures or under heating status eremacausis takes place.On waterproof construction, adopt hidden to use for fear of the generation of these phenomenons waterproof roll of the present invention, the ultraviolet ray of outside is all blocked or absorbed with light tight solid.But the consideration production, illumination in transportation, storage, the work progress and the degraded of the eremacausis under the normal temperature will add photomask agent and heat stabilizer and antioxidant.Waterproof roll main water barrier of the present invention adopts colour carbon black as photomask agent and heat stabilizer, adopts dilauryl thiodipropionate as antioxidant.The colour carbon black Main Ingredients and Appearance is a carbon, and its effect in high polymer has aspect three: the one, and painted, the 2nd, antopxidation, the 3rd, the ultraviolet screener effect, thus polymer is played effective stabilization.The concentration of carbon black and granularity all influence light shielding effect, and more satisfactory particle diameter is 15～25nm, and relatively Shi Yi addition is 0.5～1% of a LLDPE gross weight.
Select dilauryl thiodipropionate for use with the antioxidant that carbon black is auxilliary mutually, addition is 0.1～0.2% of a LLDPE gross weight.Sulfur-bearing antioxidant and carbon black have obvious synergistic effectiveness.
Add in the LLDPE after the carbon black, the scattered bad influence light shielding effect of carbon black is done dispersant in order to make carbon black dispersed uniform in main water barrier add the cycloalkyl hydrocarbon, and addition is 0.1～0.5 of the poly-gross weight of linea low density.
In the polyvinyl resin plastication and extrusion process, auxiliary agent is mixed together even plasticizing to be disperseed.Auxiliary agent also plays to reduce and is in the capillary effect of molten resin, strengthens compound contact effect.Fully plasticizing is to guarantee composite effect, guarantees the condition that auxiliary agent effectively disperses.The too high meeting of plasticizing extrusion temperature causes combined temp to rise, and nonwoven is melted at compound tense, influences product quality, temperature is crossed when hanging down, and it is unfavorable to plastify, and extrusion pressure increases, stiff piece, fish-eye shaped appear in carbon black dispersion inequality, main water barrier, occur the cavity when serious.Heating and temperature control exists: 200～220 ℃ of barrels, 210～240 ℃ of connectors, 180～190 ℃ of heads.
The effect that the present invention strengthens surface layer has: increase roughness and improve the bonding performance of laying; Increase mechanical strength, improve the anti-destructiveness of coiled material, improve elasticity, reduce the damage of extraneous factor main water barrier.Require surface material to meet the environmental suitability of whole material simultaneously, as temperature-25～60 ℃.Adopt spun-bond process polypropylene filament nonwoven in order to satisfy above-mentioned condition.
Polyethylene and acrylic resin are the nonpolar molecule material, stick with glue agent and are difficult for having adhesive effect preferably.It is compound that the present invention adopts the hot melt and direct press composite algorithm to carry out, once two-sided composite molding.
LLDPE and polypropylene filament nonwoven are bonding, and compound what rely on is Van der Waals force.Rely on the bonding intermolecular distance that needs of Van der Waals force enough little, 6 powers of attraction and intermolecular distance are inversely proportional to, when intermolecular distance greater than 100
The time, attraction reduces very fast, is inversely proportional to 7 powers of distance.So the pressure of compound tense is essential condition.The pressure of compound contact interface should be greater than 0.4MPa.
Polyethylene and polypropylene are the nonpolar molecule material, and dipolar forces in the Van der Waals force and induced dipole power are all inoperative, have only dispersion force to work, and mechanical bond power also has certain effect.Because rely on dispersion force bonding, the moistened surface degree is very important, it engages effective area to engaging distance, and the interface forms and all plays decisive role.The bonding compound tense polyethylene of the present invention temperature is controlled at 120～150 ℃, and the polypropylene temperature is controlled at 20～40 ℃.Polyethylene surface tension force is about 28.8dyne/cm under this condition, and polypropylene surface tension force is about 30.1dyme/cm, and at this moment polypropylene surface tension force is just helping the wetting of contact interface greater than polyethylene surface tension force.
The resin sheet of being extruded by head contacts and assists and penetrate with air through a segment distance, and temperature descends behind certain heat that sheds, and resin should be in the process that viscous state transforms to elastomeric state when entering pressure roller.If resin is in viscous state fully, the melt temperature height causes polypropylene fibre to change; If resin is in elastomeric state fully, resin surface begins crystallization, and polypropylene fibre is difficult to be pressed into the linear polyethylene surface and forms fluid-tight engagement, and bonding strength is not good, does not reach composite demand.Be controlled at 120～150 ℃ based on these factors combined temp of the present invention.
Polypropylene filament nonwoven in the recombination process, its temperature will keep being no more than 100 ℃, the rigidity that tacryl is necessary, and assurance is compound closely with polyethylene, does not cause the polypropylene fibre sex change again.For making the polypropylene fibre temperature be no more than limit, take necessary cooling provision.Cooling realizes by two aspects, the one, and the polyethylene filament nonwoven enters before the combined state air-cooled, and make it temperature and be lower than 40 ℃, the 2nd, compound back contacts heat radiation and wind-cooling heat dissipating to product.The former guarantees polypropylene filament non-woven fabrics fiber rigidity, the latter guarantee its not the reason heat spread out of and make polypropylene fibre to change.
