Abstract

A method of installing an impervious barrier onto a roof is described. A reinforcement textile (20) is initially applied to a roof substrate (40). Thereafter, an elastomer composition (50) is sprayed onto the reinforcement textile (20). The deposited elastomer composition (50) lifts the reinforcement textile (20) from the roof substrate (40) and embeds it into the elastomer composition (50), leaving no visible sign of the reinforcement textile. The processing steps are the opposite of those of the prior art. The processing is possible in view of the characteristics of the disclosed reinforcement textile, the elastomer composition, and the conditions under which the elastomer composition is applied to the reinforcement textile.

Description

The mounting method of fully adhered roofing membrane
Affiliated field
The present invention is broadly directed to the technology that impervious barrier is installed on the roof.More particularly, the enhancing fabric that the present invention relates to set in advance on roof substrate is set up the method for fully adhered roofing membrane by coating liquid elasticity thing.Background technology
The annual light grade roof skin-material of installing of the U.S. is used 4,000,000,000 square feet approximately.Most of roofs skin-material is used to commercial and building roof industry.Roof Material also can be used on the structure such as dangerous material storaging tank, domestic use of water container and water pipe etc.Generally speaking, the roof skin-material has three types: ballast-type, mechanical connection type and whole binding type.The present invention relates to the roof skin-material of whole bonding.
The roof skin-material of whole bonding can be coated onto a kind of resin (being also referred to as the elasticity thing) on the roof substrate by spraying, and this is a kind of main method.Thereafter a kind of enhancing fabric roll cloth of braiding on resin, to guarantee the integraty of surface structure.Later on different physical units is used for mechanically imbedding and strengthens fabric in resin.At least be temporarily make resin aging moulding become impervious barrier thereafter.
Fully adhered roofing membrane material problem at large is to form many holes.These holes are the tender spots on top layer, roof, have slackened the antiseepage effect on top layer, and make the too early damage of roof system.These holes hold the air that is full of water, and expanded by heating also produces bubble.The forming process of bubble is quickened along with the thickening of year roof surface blackening of a specified duration and long-pending thing.In a single day a bubble just forms perforation easily, thereby roof substrate is exposed under the various weather conditions, and soon damaged.
Hole usually is irregularly formed in roof substrate.Hole also produces because of the mistake of applicator when bonding is installed.The mistake of applicator has comprised uneven cloth and/or bonding in shortage.Because its visual signal is minimum, the defect of applicator in the bonding process is to be difficult to find in installation process.Notice that the mounting process that flattens the enhancing fabric in resin with broom and machinery helps reducing defective.Yet this method labour intensity is big and cost is high.The installation process on top layer, roof is provided and in installation process the visual feedback information of issuable mistake be that people wish very much.Therefore, be a method that reduces labour cost and produce the top layer, roof that is difficult for the generation defective.
Hole be not easy detected.Also be difficult to remedy even detect.Therefore, hole causes the too early damage in top layer.About 40% of the roof surface structure of whole bonding can only reach expected service life average approximately 55%.Therefore, be desirable to provide a kind of mounting technique of more durable roof surface structure of difficult generation hole.Certainly, so the top layer, roof must meet all relevant building standards.In addition, if such top layer, roof help environment and also energy-conservation be desirable.
A kind of way that can solve improvement top layer, roof is to put upside down installation process.In such method, strengthening fabric elder generation on roof substrate secondly is to strengthen injection and infiltration resin on the fabric by roller cloth.
Getting rid of a kind of like this may be consideration for some reality.For example, in any case, when highly pressurised liquid stream is forced by air, can suck some air.When forcing it can suck more air when strengthening fabric.Therefore, the use of Guan Yong resin and yarn fabric can cause producing millions upon millions of the final bubbles that form and become hidden danger in the top layer, roof.So, wish to eliminate the air entrainment problem that strengthens in the fabric that presets.
The other problem of institute's suggesting method is that resin is imbedded in the enhancing fabric, rather than resin flow is crossed all surface of yarn fabric.Therefore, place the way that strengthens fabric in advance, must become the center so that after application of resin, strengthen fabric in the special overall technology of development aspect the enhancing fabric in order to use on the top layer, roof.
Another obstacle of realizing this scheme is to find a kind of high solid bonding content synthetic, and it will have excellent adhering, to strengthening fabric suitable interaction be arranged injection.According to top layer, roof constructional materials standard-required, the solid content of the water-soluble bonding roof Material of precuring roof substrate will be not less than 50%.This quite high solid content has been cut down can be effectively and the use of the interactional viscosity value of prepositioned enhancing fabric.Brief summary of the invention
The present invention relates on the roof, install a kind of method of impervious barrier.At first a kind of enhancing fabric is laid on the roof substrate.A kind of elastic composition be ejected into enhancing fabric on thereafter.The elastic composition of deposition rises the enhancing fabric on the roof substrate, and strengthening the fabric submergence, can't see some vestiges that strengthen fabric.The step of this method and habitual technology are opposite.In view of the characteristic of described enhancing fabric and elastic composition and elastic composition are applied to the condition that strengthens on the fabric, this technology is feasible.
The present invention is favourable.Because before using elastic composition, the enhancing fabric can be installed quite easily.When being installed, the after-applied elastic composition of enhancing fabric can be observed the feedback information of elastic composition overlay capacity.If strengthening the elastic composition that has applied lazy weight on the fabric operation, " window " then appears, and be visible by flow elasticity thing layer.This provides the range estimation indication information for the coating technology personnel.Need more elasticity thing.This typical situation makes the technician through short-term cultivation just can finish technology of the present invention.This situation has also reduced the possibility of potential defective, and these defectives can cause long-term maintenance problem.
Method of the present invention has used a kind of water to generate the elastic composition of fluid bonding/waterproof.This material has sufficient storage viscosity, guaranteeing even suspension, and enough low viscosity is arranged when mounted to have guaranteed and can appropriate interaction have been arranged with the enhancing fabric of settling in advance.The chemical characteristic of elasticity thing provides concentrating in last top layer, tack coat top of a kind of satisfaction to strengthen on the fabric.The chemical characteristic of described elasticity thing has also solved the air entrainment problem.Otherwise can hinder this The Application of Technology.Brief description
In order to understand characteristic of the present invention and purpose better, described in detail in conjunction with the accompanying drawings in the back.Wherein:
Fig. 1 can be used as the plan view that strengthens fabric according to the present invention.
Fig. 2 can be used for the enhancing fabric plan view that supports pressing structure that has of the present invention.

The present invention relates to a kind of new method that fully adhered roofing membrane is installed.Method of the present invention is to put upside down the step on habitual top layer, installation roof.In other words, in the present invention, a kind of new enhancing fabric that is called gauze (scrim) is set in advance on roof substrate, thereafter, a kind of elastic composition of novelty is applied on the gauze that pre-sets.Method of the present invention as described below requires to select suitable chemical composition/solid content/viscosity and interactional elastic composition, so that gauze automatically aligns down in place.In addition, if when the use of elasticity thing is deficiency, then gauze has visible exposed point, shows to add the elasticity thing.This visual feedback impels defective to reduce.In addition, therefore the exposed point even without also recognizing through the operator who trains after gauze is handled through elastic composition has reduced labour cost.This kind elastic composition has been avoided producing empty problem because of the incomplete immersion of gauze.Resulting roofing materials meets every building standard fully, and is energy-conservation and help environment.
Real characteristic of the present invention and its benefit can be understood more completely by following data.Elastic composition of the present invention has three class additives: I. processing aid, II. cementing agent, III. performance enhancers.Be the scope of relevant percentage by weight and the optimum value of various additives below.

Elastic composition of the present invention has following important characteristic.At first be about cementing agent.The percentage composition of resin glue preferably accounts for about 46.5% of total making amount in the liquid phase.But, when the elasticity thing solidified, resin glue (solid retained) was formed between 40% to 42% the weight, best 40% of the total making amount that accounts for.The numerical value of this best 40% pure polymer meets relevant norm of construction fully.This high liquid phase cementing agent solid content generally can obtain being higher than the viscosity that prescription requires, and therefore has problem when spraying this elasticity thing.In order to solve viscosity problem, in the liquid phase ingredients, to keep highly filled, keep the tackability of cementing agent, must carefully carry out the preparation of resin glue.Therefore, preferably form according to thermoplastic resin of the present invention (II, B) with the solid particle that is less than or equal to 0.5 micron; Preferably 0.1 micron solid particle forms thermosetting resin (II, A) with being less than or equal to.
Being worth another characteristics of the elastic composition resinous principle of proposition, is that resin glue constitutes mixture in conjunction with hydrophilic clay, and in fact mixture has reduced viscosity under the shear action of pump unit.After this thixotropic characteristics and other viscosity parameter will be described in.
Be worth another characteristics of the elastic composition of proposition in fact to comprise both, i.e. antifoam agent (I, H) and foam cracking agent (III, C).The characteristics of this elastic composition have alleviated the problem that air sucks injecting resin on the gauze that sets in advance when.Remedied the hole on the previous goods simultaneously.
Tell about the gauze that the present invention uses below.Fig. 1 is the plan view of gauze 20.Gauze 20 comprises mechanical orientation thigh 22 and transverse strands 24.Best, 0.005 to 0.025 inch, optimum value is about 0.020 inch to mechanical orientation thigh 22 wide (Fig. 1, by left-to-right); Thick (Fig. 1, directly to) between 0.003 and 0.005 inch, optimum value is 0.004 inch.Best gauze per unit length inch has 7 to 11 strands, and it is 9 strands that optimum value is about the per unit length inch.Best machinery directly to tensile strength be the per unit length inch between 120 to 160 pounds, optimum value is about 140 pounds.
Transverse strands 24 wide (Fig. 1, top are to the bottom) is between 0.030 to 0.070 inch, and optimum value is about 0.050 inch, and thick (entering Fig. 1 direction) is about 0.001 inch.In a kind of preferred embodiment, the per unit length inch has 7 to 11 strand 24, and optimum value is 9 strands, best machinery directly to tensile strength be the per unit length inch between 110 to 150 pounds, optimum value is about 130 pounds.
The eyelet 26 of X axis is preferably between 0.060 to 0.10 inch in gauze 20 matrix, and optimum value is about 0.080 inch.In gauze 20 matrixes Y-axis to eyelet 28 be preferably between 0.035 to 0.075 inch, optimum value is about 0.055 inch.
In one embodiment, the total width (lateral dimension) of gauze is between 40 to 62 inches, and total length (mechanical orientation) is about 600 feet.Every yard weight is preferably in 2 to 6 ounces, and optimum value is about 4 ounces.This light relatively weight has reduced the actual weight of building structure load.
Mechanical orientation thigh 22 and transverse strands 24 can form with scribbling the last wire drawing of polyacrylic polyester fiber.These strands are not woven together.Fig. 2 has illustrated that gummed thigh 22 and gummed thigh 24 can be the filaments 30 of the bonding light weight of machinery, is for example formed by polyester.Filament 30 comprises mechanical orientation section 32, is connected in above the 32A of transverse strands 24 simultaneously and below the 32B.Filament 30 has also comprised " it " font section 34 that connects contiguous mechanical orientation thigh section 32, shows as Fig. 2.
Notice that the gauze 20 in order to handle announcement is stable, flexiblely be enough to connect on the irregular roof substrate.These characteristics can be determined the rational quantity of gauze and allow that formation is by the sagging half inch edge of 90 degree.In addition, gauze has enough pliabilities, on the intersection point 36 of each strand 22 and 24,20 the gram power removable at least one.In other words, a mobile mechanical orientation thigh 22 or transverse strands 24 necessary power are no more than 20 grams on an intersection point 36.Power be act on the gauze plane a bit, be parallel to one and perpendicular to another strand.
Disclosed gauze 20 has satisfied these requirements.Disclosed gauze 20 is that the Ecostar serial number of being made by the Georgia State, Lagrange, Milliken limited company is the P-375 product.
Also can adopt the structure of the relevant gauze in the scope of the invention.For example thigh 22 and 24 can be made independently with any material, or smears the top layer, roof that the back forms waterproof with the elasticity thing.Again for example, a butyl polypropylene moisture thermosetting, carboxylated can be employed.To have the tensile strength of demarcation be 200 pounds of per unit length feet to the top layer, roof completely.A kind of adhesion has replaced mechanical pressing or braiding, can be applied on each intersection point 36.
Gauze 20 can twist on the presshoard tube.When the top layer, roof of bonding was installed according to the present invention, gauze 20 was that roller is opened up on the roof substrate, and mechanical orientation thigh 22 is directly contacted with roof substrate.This means that transverse strands 24 is that height places on the roof substrate.
Fig. 3 has illustrated that the exhibition of gauze 20 rollers is on roof substrate 40.Typically roof substrate 40 is adiabatic panellings of metal, or some other can mounted in advance roof Material, as the pitch member, or the gluing sheet stock.Roof substrate should clean dried.
Gauze 20 is that no damping roller applies, and generally is to be with continuously in the whole length of roof substrate 40 and wide one.Thereafter, another gauze 20 band rollers apply and stretch out outside the base material, and lap applies at prior mounted roller and is with, and is preferably in overlapping 2~6 inches between the two, and optimum value is about 4 inches.The zone of lap is called edge 42, is shown in Fig. 3.In case the gauze roller uses up, another new gauze roller begins the deposited lap of roller and applies a good end already, and the lap end is preferably in 6 to 10 inches, and optimum value is about 8 inches.This part is called end overlap joint 44.This end overlap joint 44 and edge 42 overlap the zone and are called "T"-shaped overlap 46.Available habitual technology is cutting out the obstruction that is occurred on the suitable roof substrate on the gauze 20, as the otch of smokestack.
After placing gauze in advance on the roof substrate 40, the elastic composition of having stated is injected on the gauze.Fig. 3 has illustrated that the stock 52 with injector head 54 is used to provide elastic composition 50.Injector head 54 is preferably formed as one 65 degree segment angle (apart from stock 52 a center lines left side 32.5 degree, right 32.5 degree).Preferably injector head 54 is controlled on the roof substrate 40 between 14 to 28 inches, and optimum value is about 24 inches.This causes one to spray vestige 56 and be approximately 36 inches and take advantage of 3 inches.
As shown in Figure 3, best, the length of spraying vestige 56 is parallel with mechanical orientation thigh 22.Spraying technique personnel walk about 36 inches from one side of gauze 20 to another side, return then.Played cementation before returning.Thereby formed a typical unrippled square.Shown in the thick arrow of Fig. 3.
It is important keeping stock 54 injector heads to be located immediately on the gauze 20, so that in fact the elasticity thing 50 of spraying is beaten at gauze 20 in that plumbness is following.In other words, elasticity thing 50 is directly aimed at gauze 20 downwards.If depart from vertical orientations more than 15 degree, a debatable loss has been arranged on the impact velocity of disclosed working pressure, it has influenced the interaction of elasticity thing 50 and gauze 20.If elasticity thing 50, then can not be thought the vertically coating of gauze 20 with defined much larger than 15 degree in the orientation upper deviation.The zone at the edge 42 on the gauze 20 often is vertical missing districts of the coating elasticity thing 50 of appearance.
The frequency that moves back and forth between the both sides on gauze 20 width should guarantee that all openings of gauze 20 all fill up, and head has also carried out even filling simultaneously, is covered by the putamina of layer of even elasticity thing.
During the stone dividing plate of roof substrate before installing, to have replaced the irregular of roof surface less than 1/16 inch to 3/8 inch or bigger level and smooth thermal insulation slab face.General requirements is that 5 gallons minimum spray cloth speed pours into and cover gauze 20 for per 100 square feet.Gauze 20 usefulness stocks 52 then are capped by 2 or 3 times.The thickness that this spray cloth speed generates wet elasticity thing is 0.080 inch.The roof substrate surface seldom is fully smooth, and therefore the average thickness of wet elasticity thing is normal between 0.090 inch to 0.100 inch.When solidifying, wet elasticity thing is loss 30% approximately.Therefore, wet elasticity thing thickness is approximately under 0.80 inch the situation, and the thickness of the elasticity thing of curing is approximately 0.060 inch (60mils).
Stock 52 is equipped with pressure meter 60.Stock 52 connects a flexible pipe 62, and flexible pipe 62 is connected on the pump 64.Pump 64 is extracted the elasticity thing 50 of some out from a round can 66.Typically, round can 66 is to be placed on the ground line, rather than is placed on the roof substrate 40.As mentioned above, the elasticity thing has formed highly filled state, has the fixedness content up to 70%.Static viscosity in round can 66 must be more than 3000 centipoises, guarantee that solid remains under all even state that suspends fully, and seldom need after storing or need not stir.
Make it by cracking on the gauze 20 in order successfully to spray the elasticity thing.In the scope of general-purpose pump, under the shear stress of mechanical pump, the elasticity thing necessarily is the trend of thixotropy.The viscosity that transmits the elasticity thing can not be greater than 800 centipoises at injector head 54 places.When being equal to or less than this viscosity, minimum contact pressure is 300psi.Suitable head pressure scope is 250 to 500psi.
Along with the increase of distance that the top layer, roof is installed and height, require more powerful pump and bigger caliber to remain on minimum critical pressure on the spray site.Be lower than this minimum head pressure will cause below and gauze 20 on and below dryin-up point between the roof substrate 40.General several hrs only after initial solidification is carried out on the top layer, roof, these dry places and vacancy will cause generating bubble down at solar irradiation.Edge 42 and "T"-shaped overlap 46 elasticity things at mounted gauze 20 must entirely spray 2 to 3 layers respectively, and local injection will be carried out in the position of special fragility.Therefore, the operator needs to use full-bodied elasticity thing to spray whole above-mentioned zones through conscientiously training.
A pressure meter is installed on pump 64, is observed pressure and the variation of understanding each operation generation in the jet rod for the operator.As the several high viscosity elasticity thing capsules in round can 66; In flexible pipe 62, set up diaphragm on the difference; The wearing and tearing that cause at the stroke range internal cause low-pressure " signal (blips) " of pump 64; The operator attempts using the height change of being had a few on stock shower nozzle 54, causes in fact transmitting under low-pressure.Therefore, be the litmus test that guarantees that enough jet velocities are done, a suitable action bars that pressure meter 60 is housed must be arranged.Pressure meter 60 with wide range and clear card need be put in place, and the operator can check frequently that stock pressure transmits the critical minimum that reaches 300psi.When pressure is reduced to when being lower than this minimum, then the pressure regulator on pump 64 will be adjusted.
In view of above-mentioned parameter, the elasticity thing of application has 20 to 60% will be injected into 40 of the soffit of gauze 20 and roof substrate.Is the shower nozzle ejection at the elasticity thing from spraying stock 54, and beginning mixes with air.At the injected transverse fiber plate 24 that passes unlimited gauze 20 and broad below of elasticity thing, more air is inhaled into simultaneously.7000 feet of height above sea level and be lower than the elasticity things that 7000 feet places are injected in below the gauze 20 and can account for 15% of volume at least, inhaled air has desirable form and distribution.
Aforesaid bubble breaking agent in the elasticity thing is activated by this gas phase, air in the elasticity thing matrix arrives below the gauze, air in elasticity thing matrix expands immediately when being higher than atmospheric pressure a little and rises having one, extrude transverse strands 24, rise from the position of following broad, cause that gauze moves up.When air bubble rises, the side of passing through the transverse strands gauze continually that they are a large amount of, rather than both sides are simultaneously.
The design of gauze allows mechanical orientation thigh 22 and transverse strands 24 to operate independently.Bubble when leaving the elasticity thing is done axially rotation ascending motion around transverse strands, and the hole of generation is filled by highdensity elasticity thing on every side immediately.The molecule tension force of the elasticity thing of some existence has formed the obstruction of gauze 20 motions.Between the relative power of these predictable concentrated power that cause and gauze 20 embeddings, balance each other.Gauze 20 is positioned at 15% to 65% of employed elasticity thing average total thickness.
It is consistent that the fiberboard of above-mentioned connection gauze 20, gauze 20 can seal on the roof substrate irregular projection and crack.When spraying the elasticity thing, under wet situation, under irregular elasticity thing and fiberboard abutted against together condition, fiberboard was to move easily, has obtained the about identical total cross section under most of irregular conditions.
The course of injection of beginning still deficiency surpasses deviate significantly and irregular hole takes place the effectively filling of gauze.The elasticity thing that can not fall into box leaves the gauze of obviously visible discernible exposure and falls minimum point erratically.This exposure place can be sprayed with the elasticity thing again.
When solidifying, volatilizable thing flashing off, the elasticity thing shrinks, and soft gauze sucks and removes the projection and the epidermis of the minimum on the roof substrate 40.This process constitutes a bag compression process.The top layer, roof that obtains is to use the resin of gauze and curing near whole roof substrate isohypse.Do not use excessive elasticity thing to go to improve the ability of improving withstand load, such as piercing through, tear and pressurize damage.The bag phenomenon that contracts also allows to keep the thickness on the top layer, roof of a definite form, guarantees top layer, whole roof and consistent high strength properties.
After the installation and curing on top layer, roof of the present invention, a kind of diaphragm shell is formed on the top layer, roof, reduced ultraviolet degrading.The protection putamina of any kind can use in technical field, is exactly a kind of protection putamina and particle swarm of reflection as paint.
Those skilled in the art are readily appreciated that advantage of the present invention.It is relatively easy at injection elasticity thing gauze being installed in the past.Gauze is installed uses elasticity thing of the present invention to provide visible feedback information to determine the total amount of elasticity thing later on.If the elasticity thing use quantity not sufficient, gauze presents the elasticity thing shell of infiltration, and a visible sign to spraying technique is provided, and requires better elasticity thing.Such information providing technician carries out the training of short-term can use technology of the present invention.These information also can reduce the possibility that has potential defective significantly, do not need repairing for a long time and various infringements take place.
The elasticity thing that method of the present invention is used high relatively solid content has low use viscosity, and allowing with the gauze that sets in advance has suitable interaction.The prescription chemistry of elasticity thing is acceptable on gauze bonds the top layer, roof at last.Disclosed elasticity thing has also solved the problem that air is mingled with.Otherwise this technology can not be employed.
Elasticity thing of the present invention and top layer, resulting roof are energy-conservation, be of value to environment and meet whole building standards fully.
More than the explanation of specific embodiments of the present invention is used to explain and illustration purpose.They do not plan the present invention is confined to described concrete form.In view of above-mentioned, obviously, it is possible making multiple change and variation.Concrete embodiment selected is for principle of the present invention and his practical application are described best, other technology is applied among the present invention and with diverse ways changes concrete problem, deacclimatizes various needs.Claim that the present invention is following and the principle scope that equates are clear and definite purposes.
