Description
Technical field
The utility model relates to the building waterproofing technique field, particularly a kind of high-level waterproof requirement that can reach long-term non-leakage water, helps improving the composite water-proof system of building comprehensive waterproof capability.
Background technology
In recent years, along with the fast development of social economy and urban construction cause, people required more and more higher to building waterproof, even had proposed the high-level waterproof requirement of long-term non-leakage water.Aspect building waterproof, the rubber asphalt material is gone through because of its excellent water resistance and is occupied leading position, and rubber-asphalt waterproof material product commonly used at present mainly contains synthetic rubber asphalt water-proof coiled material and Rubber Modified Asphalt Waterproof Coating.The characteristics of synthetic rubber asphalt water-proof coiled material are that the material thickness is even, easy construction and quick, are widely used on the building flat surface, and its weak point is: applicable surface is wideless, and the stickiness on non-burnishing surface is relatively poor; The construction of employing hot melt, not only poor stability but also consumes energy and contaminated environment; Reliable long-term working is relatively poor, and the waterproofing course of generation has the handing-over seam to exist, and except that in use taking place easily the seam crossing percolating water, the phenomenon that waterproofing course is heaved, peeled off or rupture, chaps takes place easily also.The advantage of Rubber Modified Asphalt Waterproof Coating is; Can adopt direct coating process construction, it is lower that convenience and cost are set; Widely applicable, building regular or irregular basal layer surface and complex node position all there is very strong attaching adaptive capacity, the rubberised layer that forms does not have the handing-over seam, overall permanence is good, its weak point is: owing to solidify fast, all wayward at operating process floating coat thickness and uniformity coefficient, generation causes local drainage because of the part is thin easily.So, existing rubber-asphalt waterproof material, no matter be synthetic rubber asphalt water-proof coiled material or Rubber Modified Asphalt Waterproof Coating, they be arranged on separately the single formula waterproofing course that generates on the building all the actual waterproof effect of ubiquity and useful working life cannot say for sure the weak point demonstrate,proved, thereby can't satisfy the high-level waterproof requirement of the long-term non-leakage water of building.For this reason, the someone has proposed to adopt simultaneously Rubber Modified Asphalt Waterproof Coating and synthetic rubber asphalt water-proof coiled material that the imagination of complex waterproof layer is set, and to remedy weak point separately, satisfies the high-level waterproof requirement of long-term non-leakage water.But owing to existing Rubber Modified Asphalt Waterproof Coating is to aim at direct coating to be arranged at develop on the building surface concrete a kind of and to have the water-repellent paint of ability to cure faster, and the coating after solidification process be exactly contact with material around bonding, mutual location process, so in the work progress of complex waterproof layer is set, except the requirement that will certainly produce quick setting, also surrounding edge is existed the requirement of positiver sealing, with the basic waterproofing course and the building concrete surface of realizing constituting by Rubber Modified Asphalt Waterproof Coating, and the reliable bonding and surrounding edge between the appearance waterproofing course inner surface that is made of the synthetic rubber asphalt water-proof coiled material is to the positiver sealing effect of complex waterproof layer.To this scheme, meet reason in theory, also be feasible in the practical operation, can greatly improve and prolong the water resistance of building.But its a fly in the ointment is: because the building of the building finished product concrete surface sealant that can take place to solidify on crack, the complex waterproof layer edge situation that also can ftracture in the course of the work in the course of the work, thereby influence the long-term water resistance of building.
Summary of the invention
The purpose of this utility model be to overcome existing waterproofing course ubiquitous actual waterproof effect and useful working life cannot say for sure to demonstrate,prove, can't satisfy the deficiency of the high-level waterproof requirement of long-term non-leakage water, a kind of a kind of composite water-proof system that can guarantee to satisfy the high-level waterproof requirement of long-term non-leakage water is provided.
Composite water-proof system body of the present utility model is made of complex waterproof layer and appearance topping, be characterised in that complex waterproof layer is made of inner base layer and external reinforcing layer, the appearance topping is by polyethylene sheeting or nonwoven, pea gravel concreten and reinforced mesh constitute, wherein: the described inner base layer of a. by a kind of have at normal temperatures be solid-state behind the ingress of air, but under the sealing oxygen free condition, keep flexible glue tacky state double grading, can adapt to substrate surface deformation and bearing capacity, help to solve waterproofing course and scurry water problems, by major ingredient pitch with include thermoplastic elastomer (TPE), modifier, tackifier, plasticizing agent, the non-curing waterproof gluing that the pair material blend of dilution auxiliary agent and inserts constitutes is filled the post of, major ingredient pitch is wherein filled the post of by petroleum bitumen, thermoplastic elastomer (TPE) is filled the post of by thermoplastic styrene butadiene rubber, modifier is filled the post of by low-molecular-weight polyisobutene, the tackifying resin that tackifier are made up of Petropols or phenolic resins is filled the post of, plasticizing agent is filled the post of by polyolefin, the dilution auxiliary agent is filled the post of by the ethyl acetate organic solvent, inserts includes carbon black and the calcium carbonate of fineness between 160～200 orders is filled the post of, and the component weight proportion is: major ingredient pitch 40～50%, thermoplastic styrene butadiene rubber 5～10%, polyisobutene 4～8%, tackifying resin 3～8%, polyolefin 8～10%, carbon black, calcium carbonate 19～21%, dilution auxiliary agent 8～10%; B. described external reinforcing layer by a kind of main body by upper covering layer, lower covering layer and form by the middle waterproofing course that modified bitumen sizing material layer is filled the post of, it is good to have high and low temperature resistance, bonding great efforts, high and outstanding elongation per unit length and the flexibility of surface tensile strength, fixedly gluing makes it be difficult for being subjected to displacement when the waterproofing course local pressure, being difficult for that in use waterproofing course takes place heaves, peel off or crack performance, can satisfy long-term non-leakage water instructions for use high-performance synthetic rubber asphalt water-proof coiled material (be called for short " waterproof roll ") fill the post of, upper covering layer wherein is by polyethylene polypropylene, polyethylene film or metal aluminum foil are filled the post of, lower covering layer is filled the post of by the needle-punching polyester nonwoven, modified bitumen sizing material layer is made by by adding modifier in major ingredient pitch pitch being carried out comprehensively modifying, include major ingredient pitch in the component, by having the pitch of improvement low-temperature characteristics function, the high molecular polymer of the tackifying resin that includes thermoplastic styrene butadiene rubber and form by Petropols or phenolic resins and have the asphalt high-temperature of improvement characteristic functions, stable by chemical property, the modifier that the inserts that the French chalk of fineness between 160～200 orders filled the post of combines and the modified bitumen sizing material of machine oil constitute, and the weight proportion of its component is: pitch 40～60%, thermoplastic styrene butadiene rubber 4～14%, tackifying resin 1～5%, machine oil 8～10% and French chalk 27～31%.
