Description
Technical field
The utility model relates to a kind of waterproof roll, the self-adhesive modified asphalt waterproof rolling material that particularly a kind of lamination intersection film strengthens.
Background technology
Self-adhesive modified asphalt waterproof rolling material is a kind of new type waterproof coiled material growing up after the nineties in 20th century at home, it is a current developing direction of building waterproof coil in the world, mainly that cold self-adhesion construction has and there is no naked light compared with traditional building waterproof coil, not fire hazardous, solvent-free pollution, the advantages such as construction safety environment friendly convenient, Shen Shou buildings waterproof circle is the favor of unit in charge of construction especially.Therefore be rapidly developed at home in recent years.But such adhesive waterproof coil also has fatal technological deficiency, constructs affected by environment very greatly, just has excellent characteristic, the guarantee construction quality while therefore only having construction environment temperature higher than 10 DEG C of sticking when generally speaking such material is more than 10 DEG C.Thereby the dust of job site etc. often causes the adhesive surface of coiled material to be stained and is difficult to ensure that the bonding of coiled material forms completely sticky (only reaching less 75% is bonded to basic unit) in addition.The unique channel that solves this technological deficiency is to improve the problem that stains of sticking characteristic and solution adhesive surface that (mainly refers to 5～10 DEG C) under modified pitch self-adhesive cryogenic conditions.In recent years some disclosed bibliographical informations some solutions, for example:
Document 1, Chinese Patent Application No. is 200910114456.X, patent name is " carrying out the waterproof roll of the collaborative bonding of chemical crosslinking and physics mortise and tenon with concrete ", this disclosure of the invention a kind of wet paving overlay waterproof roll, be modified pitch compound to be carried out on carcass to dip-coating, control thick sizing, overlay film, the techniques such as rolling are made, and described modified pitch compound is modified pitch, plasticizer, antioxidant, functional aid and filler, preparation method is placed in matrix pitch in retort, adds tackifier, random polyethylene and SBS, be mixed evenly, and heats up, and stirs 1.5-2H, then temperature dropped to 180 DEG C of left and right, then by filler, plasticizer, antioxidant, function additive is added to retort, stirs 0.5-1H, carries out fully mixed and modifiedly, is then transported to colloid mill, material is ground repeatedly, then pitch good modification is carried out to dip-coating on carcass, control thick sizing, overlay film, rolling, what be just prepared into excellent performance carries out chemical crosslinking and the collaborative waterproof roll boning of physics mortise and tenon with concrete, is called for short CPS waterproof roll.
Document 2, Chinese Patent Application No. is 201210028719.7, patent name is " a kind of pitch self-adhesive and the adhesive polymer of being made up of it are rubber water-proofing coiled ", this disclosure of the invention a kind of pitch self-adhesive, it comprises by weight percentage: pitch 45～65%, rubber oil 16～25%, SBS5～15%, SBR1～6%, Petropols 1～6%, EVA1～7%, talcum powder 10～20%.The present invention also provides a kind of adhesive polymer rubber water-proofing coiled, and it comprises the pitch self-adhesion glue-line that nonwoven layer, macromolecular sheet material layer and pitch self-adhesive described above form from bottom to top.The two ends of described waterproof roll are provided with overlap edge.In pitch self-adhesive of the present invention, contain EVA, improved the compatibility of self-adhesive and macromolecular sheet material, increased the combined strength bination of macromolecular sheet material layer.The present invention adopts the lap joint process of self-adhesion structure to solve macromolecular sheet material and overlaps insecure problem, makes overlap joint between coiled material and coiled material realize the mode of gluing glue, and the firm and solid degree that bonds is reliable, and regulation and control freely, very flexible.
The technical scheme of reporting in above-mentioned open source literature is all to bond to construct by the formula of improvement modified pitch self-adhesive with by cement mortar to solve the problem etc. that stains of adhesive surface.But document 1 is to improve under modified pitch self-adhesive cryogenic conditions sticking characteristic and making modified pitch self-adhesive have cement-bonded characteristic by adding poly-methyl ethoxy silane etc. of (referring to construction environment temperature 5～10 DEG C time) by adding butyl naphthenate, but have butyl naphthenate (poor with the compatibility of pitch) easily to move to affect from sizing surface the technological deficiencies such as Cohesion reliability, poly-methyl ethoxy silane belongs to combustible material that flash-point is lower, under the more than 180 DEG C batching condition of modified pitch, easily volatilizees and cause employment injuries or initiation fire in a large number in addition; Document 2 is to address the above problem by adding SBR and EVA, its negative effect is that the cohesive force of modified pitch self-adhesive is less thereby impermeability is poor, can only adopt macromolecular sheet material that price is relatively high as reinforcing material, if while adopting the relatively low polyester blank of price as reinforcing material, the impermeability of coiled material does not meet concerned countries standard-required, thereby has limited it yet and applied.
