Abstract
The utility model discloses an ethylene propylene diene monomer waterproofing sheet material with bonding layers, and relates to rubber waterproofing sheet materials. During construction on the site, after bonding layers of adjacent ethylene propylene diene monomer waterproofing sheet materials with the bonding layers are connected in lapped mode, the adjacent ethylene propylene diene monomer waterproofing sheet materials with the bonding layers can be closely cohesively combined after being blown by an air heater and heated and compacted, and therefore phenomenon of leakage can be effectively prevented, price is reasonable, and the ethylene propylene diene monomer waterproofing sheet material with the bonding layers is easy to use during construction. The ethylene propylene diene monomer waterproofing sheet material with the bonding layers is characterized by comprising the ethylene propylene diene monomer with the bonding layer arranged on the side edge of the front surface and the other side edge of the reversed surface, the bonding layers are coating layers of thermoplasticity rubber solution, joint intensity is high, and durability and waterproofing performance is good. Sealing reliability of combining parts between one sheet material and other sheet material is ensured, and the ethylene propylene diene monomer waterproofing sheet material with the bonding layers can be used as waterproofing layers of various projects.
Description
Technical field
The present invention relates to a kind of rubber ethylene-propylene-diene waterproof sheet.Particularly a kind ofly be composited by thermoplastic elastomer and ethylene propylene terpolymer sheet, with the EPDM water-proof sheet of tack coat.
Background technology
At present, the macromolecule water-proof sheet material that adopts in the construction work generally is vulcanization type rubber waterproof sheet material, unvulcanized rubber waterproof sheet and their composite sheet.Wherein in the vulcanization type rubber waterproof sheet material, the resistance to ag(e)ing of ethylene propylene diene rubber and application life are the most excellent in waterproof sheet, have high strength, large extension, the superperformance of high-low temperature resistant.
But because the saturability on the ethylene propylene diene rubber molecular structure has brought the difficulty of using also for made sheet material, that is exactly its bad adhesion; When large tracts of land is used, although the water resistance of EPDM water-proof sheet is good,, because EPDM water-proof sheet binder performance each other is not good enough, cause the seam between the adjacent sheet to be difficult for bonding, protect badly, often cause waterproofing course seepage or inefficacy.
Have for EPDM water-proof sheet bonding technology each other a variety of, as, with polyurethane coating edge sealing method, sealing compound edge sealing method, with the unvulcanised adhesive tape as adhesive method etc.Above method in the application of waterproof sheet, although can solve the adhesive seal of seam,, must adopt multiple-sealed and must guarantee the quality of construction technology and operation.
For this reason, during engineering was used at present, the earth system of employing bonding and sealed composite solved the sealing problem between the adjacent EPDM water-proof sheet.Namely in construction, at first with high performance adhesive adjacent EPDM water-proof sheet edge is overlapped bonding after, again the bonded part is sealed with Special seal cream, to guarantee bonding between the adjacent EPDM water-proof sheet.
But, adopting the earth system of this bonding and sealed composite, complicated construction technique needs EPDM water-proof sheet, basic unit's adhesive, the upper strata sealing compound behind the overlap joint and lower floor's sealing compound; Also will use the unvulcanised adhesive tape at thin section node in case of necessity, therefore, cost is higher, complicated construction technique.
Summary of the invention
The present invention aims to provide a kind of EPDM water-proof sheet with tack coat.At the scene
In the construction, after the tack coat of adjacent EPDM water-proof sheet with tack coat overlapped mutually, after unit heater blowing heating and compacting, adjacent EPDM water-proof sheet with tack coat just can close adhesion, effectively prevent the generation of Seepage, and reasonable price, construction is simple.
Above-mentioned purpose is achieved through the following technical solutions: a kind of EPDM water-proof sheet with tack coat is characterized in that it comprises that another side of positive side and reverse side is provided with the ethylene propylene terpolymer sheet of tack coat; Tack coat is the thermoplastic elastomer solution coatings; Such as Fig. 1, shown in 2.
The thermoplastic elastomer solution of the thermoplastic elastomer solution coatings of the utility model tack coat can be SBS toluene solution, EVA toluene solution, styrene isobutylene copolymers toluene solution etc.
Wherein,
The width of tack coat is 10cm.
The SBS toluene solution is the toluene saturated solution of styrene-butadiene-styrene block copolymer.
EVA is the toluene saturated solution of ethylene-vinyl acetate copolymer.
Styrene isobutylene copolymers toluene solution is the toluene saturated solution of styrene isobutylene copolymers.
The utility model in use, tack coat with adjacent two EPDM water-proof sheet with tack coat, mutually overlap up and down with the front edge of a slice and the reverse side edge of another sheet, make the thermoplastic elastomer solution coatings overlap joint of its tack coat, overlapping part heats with unit heater, the thermoplastic elastomer solution coatings is molten condition owing to heating up, and immediately uses the pressure roller compacting, and tack coat namely can be mutually compound.Overcome the bad adhesion of prior art ethylene propylene terpolymer sheet, protected badly, often caused the defective of waterproofing course seepage.
Because composite performance is good after the thermoplastic elastomer solution coatings that tack coat adopts and the ethylene propylene terpolymer sheet heating, therefore, the thermoplastic elastomer solution coatings that adjacent tack coat is provided with behind the overlap joint is with two ethylene propylene terpolymer sheets are compound up and down, its joint strength is high, has improved whole water resistance.
Description of drawings:
Fig. 1 is the utility model structural representation.
Fig. 2 is that the utility model uses view.
Among the figure, 1-ethylene propylene terpolymer sheet, 2-tack coat, 3-thermoplastic elastomer solution coatings.
The specific embodiment:
Shown in accompanying drawing 1,2, a kind of EPDM water-proof sheet with tack coat, it comprises that another side of positive side and reverse side is provided with the ethylene propylene terpolymer sheet 1 of tack coat 2; Tack coat 2 is thermoplastic elastomer solution coatings 3; Wherein,
Ethylene propylene terpolymer sheet 1 wide 1m;
After thermoplastic elastomer solution coatings 3 adopts thermoplastic elastomer SBS is dissolved in toluene, make the toluene saturated solution of SBS, be coated on the tack coat 2 of ethylene propylene terpolymer sheet 1 and consist of.
When being used for waterproofing, the utility model is launched to lay, adjacent two the utility model, mutually overlap up and down with the front edge of a slice and the reverse side edge of another sheet, make the thermoplastic elastomer solution coatings overlap joint of its tack coat, overlapping part is heated to 150 ± 1 ℃ with unit heater, and the thermoplastic elastomer solution coatings is molten condition owing to heating up, immediately use the pressure roller compacting, tack coat namely can be mutually compound.
The utility model caking property, durability, water proofing property are good, and more present prior art construction is simple, can be used as the waterproofing course of construction work, underground construction, subway engineering, municipal engineering.
