Description
Technical field
The utility model relates to building waterproofing technique field, particularly relates to a kind of waterproof roll, complex waterproof layer, and the production equipment of this waterproof roll and production technology.
Background technology
Domestic waterproofing industry development is long-standing, and various new material, new technology emerge in an endless stream, but buildings waterproof percolation ratio still remains high at present.In July, 2014, Chinese architecture waterproof association combines with Beijing MarketingResearchandAnalysis at zero point company and issues " national leakage of building status investigation project report in 2013 " and show: building roof sample leakage rate reaches 95.33%; Underground building sample leakage rate reaches 57.51%; Resident family's sample leakage rate reaches 37.48%.
Waterproof roll and water-repellent paint be architectural waterproof material field most important be also maximum two classes of accounting.
Complex waterproof layer refers to that jointly forming waterproofing course by one deck water-repellent paint and one deck waterproof roll (first does coating, after do coiled material), play coating seamless link and the uniform characteristic of coil thickness by this, and then raising waterproofing quality, be a kind of waterproof technique actively promoted in current construction work.
Visible complex waterproof layer way is more in the market, but all there is various insurmountable problem more or less, simply enumerates some below:
One, the material compatibility issues of coating and coiled material.As incompatible with coiled material wood property in coating, then needing, separation layer (as polyester non-woven fabric, cement mortar etc.) is set between separately and accelerates other adverse effects such as migration to avoid corrosion mutually or plasticizing agent occurs.And the risk that separation layer can cause water channelling wantonly between coating and coiled material is set, cannot give full play to the two mutually by, make up to improve mutually the effect of integral waterproofing reliability.
Its two, the confinement problems of construction technology.As adopted Hot-melt construction modified bituminous pitch coiled material above organic coating, then coiled material hot-melt adhesive process Flame can burn coating, certainly will cause the impaired of the performance of organic coating own, thus reduces waterproof effect and application life.
Its three, the film forming problem of solidification of coating.As pasted coiled material immediately after emulsion type or cement-base waterproof coating brushing, then there will be coating quality of forming film difference or even completely cannot the problem of film forming.Even if paste the way of coiled material again after adopting coating to solidify completely, its sticking Quality also cannot can ensure because of reasons such as film coated surface secondary pollution, binding material stickiness are limited completely.
Its four, range of application limitation problem.Current, the compound way of uncured rubber-asphalt coating and all kinds of coiled material is applied more, and waterproof effect is also comparatively reliable, but because of coating almost noncohesive characteristic itself, after facade application, very easily occurs problems such as gliding, come off.Uncured rubber-asphalt coating is (this process consumes electric power or fuel about reheat to 180 DEG C at the construction field (site), and produce a large amount of glance coal contaminated environment), this high-temperature material is once touch the person, then scald and must occur, when especially constructing on outer wall of basement scaffold, consequence can be more serious.
Its five, the existence of coating helps limited for solution coiled material overlap joint itself or this weak link of docking site, and the leakproofness of coiled material layer seam in most cases still relies on coiled material itself and overlaps or the degree of reliability of butt-joint process.And this degree of reliability is lower in many cases.
The title that polyurethane water-proof paint have " liquid rubber " is one of best water-repellent paint of current combination property, the waterproof, seepage control at the position that can be used for soaking for a long time.This material solidify to form waterproof film by reaction after brushing at the construction field (site), it is a kind of waterproofing process of long-life (20 ~ 50 years), but because of the restriction of job site operating procedure, monitoring means itself, the problem such as easily there is became uneven, use inferior materials and turn out substandard goods, it is used alone the query be vulnerable to from customer, monitoring party.
Thus, find one can match with polyurethane water-proof paint, and the waterproof roll reliably forming complex waterproof layer have pure technology and commercial value.
Waterproof roll common at present mainly comprises polymer membranes and polymer modified bituminous waterproof sheet material.The modes such as polymer membranes is suppressed by the completely sticky or empty paving of scumbling bonding adhesive as PVC, TPO, EPDM etc., machinery is fixing are constructed, itself and claimed layer of structure bond and insufficient (water is once conveniently may form " channelling " and cause large area seepage under entering coiled material), and the connection of its length limit seam is often through bonding adhesive (or adhesive tape) bonding or hot air welding, its complex process, require high to workman's technical level, more difficult grasp; The bonding when water resistance of bonding adhesive itself, lamination are constructed between two layers of coiled materials is also worrying link.Polymer modified bituminous waterproof sheet material (hot melt class, self-adhesion class, wet paving class) bonds with basic unit and seam connects relative simple, but it is still very high to the requirement of workman's sense of responsibility, technical level, and due to the restriction of raw material itself, the application life of this kind of waterproofing materials is generally on the low side, generally three, five years to ten several years not etc.
Facts have proved, polyurethane water-proof paint and above-mentioned two class waterproof rolls cannot form reliable complex waterproof layer.
Chinese patent CN202156081U discloses the waterproof and dampproof coiled material of a kind of polyurethane composite flame-retardant.This coiled material is mainly used in a kind of material of pipeline and equipment surface protection, is made by thermoplastic polyurethane (TPU) coating of adding fire retardant in the top layer compound of glass fabric.

Chinese patent CN204183986U discloses the anticorrosion waterproof roll of a kind of polyurethane coating film.This coiled material is provided with monocomponent polyurethane film layer in macromolecule waterproof lamella both sides, be provided with enhancement layer between monocomponent polyurethane film layer and high molecular sheet sheet material layers, be applicable to some occasions to waterproofing materials occasion serious corrosion as refuse landfill, Wastewater Treatment Plant etc.The both sides monocomponent polyurethane film layer of this coiled material does not run through and is formed overall, cannot realize its package action, and enhancement layer, deposits the risk of separation failure after long-term use between high molecular sheet sheet material layers.
Visible, the waterproof roll relevant with " polyurethane " that polyurethane water-proof paint and above-mentioned prior art relate to still cannot form reliable complex waterproof layer.
The process of polyurethane water-proof paint film-forming is moved forward, thickness uniformity is made in factory, composition is relatively simple, construct relatively simple, self firm complete polyurethane water-proof coiled material, polyurethane water-proof paint can be kept water-fast, durable characteristic, make it have again the advantage (easy construction of waterproof roll, duration is short, little by weather effect, environment pollution is little, thickness is even, thickness is easily grasped by designing requirement, not easily use inferior materials and turn out substandard goods), by the appropriate form of construction work in job site (at the position needing completely to glue with basic unit and allly to take, the butt joint position polyurethane water-proof paint of same material bonds as thick matter cementing agent) construction, coiled material must be reached and coating is learnt from other's strong points to offset one's weaknesses, the effect united two into one, the ratio that the thickness of coating layer of site operation is shared in integral waterproofing layer gross thickness simultaneously significantly reduces, and then reduce supervision difficulty, improve actual waterproof effect.
