Background technology
In current waterproofing work, adopt the single track waterproof roll, double-deck waterproof roll, the single track water-repellent paint is in the majority as watertight composition.Waterproof roll and basal plane bonding adopt hot melt and two kinds of modes of cold laid method.At existing roofing, in the related specifications of underground waterproof engineering, rules, above waterproof material, buildings waterproof structure, construction method, the acceptance of work are had to clearer and more definite regulation.
Although the coil waterproof layer hot strength is high, there is the defect that percentage elongation is little; The film waterproof material percentage elongation is high, but has the defect that hot strength is little.The coil waterproof layer construction adopts hot melt, and in work progress, construction quality needs strict control, and Fire Escape is wanted strict control at the scene.Coiled material adopts wet application, at the capable channeling water layer that becomes Sandwich biscuit type of watertight composition and rigid layer tack coat between basic unit.
Summary of the invention
The great drawback existed for prior art; the invention discloses a kind of complex waterproof layer; by uncured rubber-asphalt coating and waterproof roll compound use; thereby give full play to the two technical advantage separately; overcome its defect, thus improved waterproofing work quality, reduced the risk that adopts traditional coil waterproof layer or film waterproof material percolating water; Disclosed complex waterproof layer easy construction, safe and reliable, labor strength is low, has improved waterproof construction efficiency.
For achieving the above object, the present invention realizes by following technical proposals:
Uncured rubber-asphalt coating complex waterproof layer, be comprised of the uncured rubber-asphalt coating mixed and waterproof roll bonding.
By above-mentioned composition, waterproof roll and water-repellent paint twice watertight composition are combined into to an integral body, go into the single track complex waterproof layer.In complex waterproof layer of the present invention, uncured rubber-asphalt coating layer is watertight composition and be tack coat and cushion still not, after the heating of uncured rubber-asphalt coating full coat at basal plane together with the coiled material secure bond, between uncured rubber asphalt coating and basic unit, powerful dividing used in interlocked, form the firmly enclosed seal construction in full interface of bonding, reach the effect of reparation, airtight basic crack and capillary porosity, effectively prevented channeling water between complex waterproof layer and basic unit and drainage.
In the present invention, uncured rubber-asphalt coating used is the coating of being made in modifier, additive etc. by asphalt, high score, and the uncured rubber asphalt waterproof coating of PBC-328 that the present invention's uncured rubber-asphalt coating used is produced by Dong Fangyuhong, FBC-402 water-repellent paint in fashion etc. can be used for the present invention.
In the present invention, described waterproof roll is self-adhering polymer modification bitumen coiled material, polymer modified bituminous waterproof sheet material.
Above-mentioned two kinds of waterproof rolls, in the construction field extensive use, are also generally sold on market, and wherein the self-adhering polymer modification bitumen coiled material refers to the coiled material that meets " GB23441-2009 self-adhered polymer modified bitumen waterproofing membrane " regulation.The high-polymer modified pitch coiled material refers to the elastic body water-proof asphalt water-proof coiled material of carrying out national standard GB18242 (2008) " elastomer modified asphalt waterproof roll " or the plastic body water proofing asphalt waterproof roll of carrying out national standard GB18243 (2008) " atactic polypropylene (APP) modified bituminous waterproof sheet material ".、
The invention discloses the preparation method of described uncured rubber-asphalt coating complex waterproof layer, comprise that the waterproof roll that uncured rubber asphalt waterproof coating is mixed with it combines by hot sticky.
This preparation method, adopt plant equipment heating coating, and coiled material is hot sticky does not need the naked light construction at coating surface, and a peace performance is good, and labor strength is low, has improved production efficiency.
On the basis of the above, the invention also discloses the construction method of described uncured rubber-asphalt coating complex waterproof layer, after uncured rubber-asphalt coating is heated to set point of temperature, method by blade coating, spraying is constructed on the surface of basic unit, on the surface of hot coating, pastes the waterproof roll layer mixed with uncured rubber-asphalt coating.
Above-mentioned set point of temperature refer to by firing equipment by uncured rubber-asphalt coating be heated to the construction temperature required, these different series products have different set points of temperature, this temperature all provides on volume in the specification of product.
By above-mentioned improvement; the invention solves and take for a long time the present situation of coiled material as the waterproof main body; overcome the defect of independent employing coil waterproof layer and film waterproof material; complex waterproof layer set of the present invention the advantage of coiled material and coating; give full play to the advantage separately of coiled material and coating; accomplish coating and the complementation of coiled material characteristics, improved waterproofing work quality, reduced the risk that adopts traditional coil waterproof layer or film waterproof material percolating water; And can adopt plant equipment heating coating during construction, coiled material is hot sticky does not need the naked light construction at coating surface, and security performance is good, and labor strength is low, has improved waterproof construction efficiency.
And the waterproof system engineering method, solved channeling water and the drainage of going into " Sandwich biscuit type " between self-adhesive coiled material watertight composition in the wet paving engineering method of current routine and basic unit's (or structure sheaf); Effectively prevented that the SBS coiled material from adopting in the thermosol construction, because the workman operates the hollowing phenomenon that causes watertight composition to occur lack of standardization simultaneously.
The specific embodiment
In the following embodiments, the application discloses the concentrated specific implementation of technical solution of the present invention, and the present invention is not limited only to following embodiment, but is covered by claim and equivalents thereof.
Embodiment 1
Adopt the SAM self-adhering polymer of " PBC-328 " uncured rubber asphalt waterproof coating that east rain rainbow produces and the east rain rainbow asphalt water-proof coiled material of changing one's profession to carry out compound.By heating " PBC-328 " uncured rubber asphalt waterproof coating and by hot coating brushing at basal plane, then its surface of SAM self-adhering polymer modification bitumen installation of membrane.
Embodiment 2
Adopt SBS (APP) polymer modified bituminous waterproof sheet material that is in fashion " FBC-402 " uncured rubber asphalt waterproof coating and east rain rainbow, by heating " PBC-328 " uncured rubber asphalt waterproof coating and by hot coating brushing at basal plane, then its surface of SBS (APP) polymer modified bituminous waterproof sheet material paving.
According to construction method disclosed by the invention, above-described embodiment is applied to the roof, house, the outside of underground engineering wall, base plate is as watertight composition.Within 1,3,6 month after construction, detected respectively, find that complex waterproof layer intensity is good, meet the construction regulation, all ne-leakage water phenomenon, do not have the channeling water layer of Sandwich biscuit type to occur yet.
