Abstract
The invention discloses a kind of waterproof roll, the middle body thickness of coiled material is uniform, and the marginal portion of coiled material both sides interior outwards thickness in vain is gradually lowered.Periphery that the factors such as can resisting natural aging that the waterproof roll of the present invention uses in construction causes shrinks warpage, reduces the lap belt of the coil waterproof layer aging damage under natural environment, the safety guarantee provided for engineering waterproofing to greatest extent.
Description
Technical field
The structure that the present invention relates to a kind of membrane waterproofing coiled material is improved, and belongs to architectural waterproof material neck
Territory.
Background technology
Along with the scarcity day by day of natural resources, the material economy in civil construction project field is subject to day by day
To paying attention to.As engineering waterproofing must waterproof roll, can effectively prevent civil construction project
Percolating water phenomenon, the engineering waterproofing especially for longer building in service life has important
Meaning.
But, the application of waterproof roll also faces problems, wherein asks than more serious one
Topic is that the waterproof roll aging performance caused during construction and use reduces and damaged.By
Lap belt region is made in coiled material self deterioration under the environment such as long-term illumination, air, rainwater
Warpage separates and disengages so that its waterproof coverage rate is imperfect, causes the local of building surface to be leaked
The situation such as water, infiltration occurs more.
For the problems referred to above, the current solution in this area is mainly manifested in the following two kinds approach:
A kind of material composition being to improve waterproof roll, by adding anti-aging materials, resistance in the feed
Oxidation material delays the aging of coiled material, or is directly added into low orientated glass to improve material itself
That resist warping performance.But this mode needs the composition of the raw material to coiled material to improve, the most also
Product processes will be caused more complicated, thus improve production and the use cost of product,
It is unfavorable for saving waterproof material and natural resources；Another way is directly to increase waterproof roll
Thickness, this mode is without being modified production line and construction technology, but this kind of solution
Simply a kind of provisional solution, it is impossible to really overcome the lap belt region warpage of coiled material to divide
From the problem of disengagement.
From above-mentioned, this area still exists improves coiled material performance and reduces the need of coiled material cost
Want.
Summary of the invention
Applicant is in long-term production, construction and research process, after how preventing coiled material construction
Overlapping edges region warpage separate conduct in-depth research, and do not change coiled material composition and
On the premise of thickness etc., the structure to coiled material is improved, thus effectively eliminates the overlap joint of coiled material
The lap belt warpage that band causes because of natural aging factor separates the risk disengaged, and improves water-proof system
Safety.
Specifically, the present invention is achieved through the following technical solutions:
Waterproof roll, the middle body thickness of coiled material is uniform, and the marginal portion of coiled material both sides is from interior
Outwards thickness is gradually lowered.
Above-mentioned alleged thickness from inside to outside is gradually lowered and covers two aspects, is on the one hand more
Near the outward flange of coiled material, the thickness of coiled material is the lowest；On the other hand be the reduction of thickness be unidirectional
, say, that reduce region at thickness and there is not the situation of projection.
When construction, coiled material is bonded together with adjacent web marginal portion.Owing to gradually dropping
Low thickness can weaken warpage shrinkage stress effectively, even if aging causing occurs in coil edge
Shrink warping stress, owing to bond stress is much larger than shrinkage stress, does not also have separation and disengage
Problem, thus add the safety of use.
In the present invention, the degree reduced for thickness does not do particular determination, it is contemplated that maximum
Change reduction shrinkage stress, preferably marginal area and meet following geometric relationship: coiled material both sides
The lateral length b in edge thickness reduction region is not less than the thickness h of coiled material middle body, edge
Thickness reduces longitudinal height reduction h in region1Be not less than coiled material middle body thickness h 2/3.
For the ease of construction, the edge thickness of coiled material both sides reduces the thickness in region and is changed to smooth
Curved surface (including the special circumstances for facing directly).
Further, on the basis of the above, applicants studied the tool that brim-portion thickness reduces
The impact on receiving opposing contracting warpage issues of the body mode, discovery such a way is it is preferable that one end
The edge thickness of edge thickness longitudinal height reduction y and the coiled material both sides that reduce region reduce
The lateral length x in region meets following functional relationship: y=kxn, k is the real number more than 0, n
For the real number more than or equal to 1；The other end is the most symmetrical.
In above-mentioned restriction relation, x represents that on curved surface, any point is to height reduction starting position
Horizontal range, y represents that on curved surface, corresponding point are to the vertical dimension of middle body top edge.At this
In the case of, the perigee distance thickness of marginal portion curved surface reduce the level of starting position, region away from
From for b, it is h1 that corresponding thickness reduces distance.
In these cases, the shape of coil edge shows as recessed.Owing to this kind of geometric surface exists
Can maximally effective opposing shrink and warpage (surface tension that geometry causes and receipts on mechanics
Contracting power in opposite direction), thus effectively overcome the appearance shrinking warping phenomenon, in combination with
With the bond area in adjacent web overlapping edges region, preferably avoid coil edge and separate de-
The problem opened, it is ensured that the safety of use.
In the present invention, it is not limiting as the bonding mode of adjacent waterproof roll overlapping regions, bag
Include but be not limited to use the lap belt of bonded adhesives bonding coiled material, use jointing tape bonding coiled material
Lap belt, the lap belt etc. of the bonding coiled material of self-adhesive.
As it has been described above, the present invention is to be improved the technical problem solving to be correlated with by geometry,
Therefore the present invention is not limiting as which kind of waterproof roll is specially, and on market, existing coiled material product is equal
It is applicable to technical scheme, includes but not limited to the coiled material of single material, two-layer not
The coiled material of same material produced with combination one-tenth or the coiled material of more layers；Preferably, the volume of the present invention
Material is the three-layer type membrane waterproofing coiled material of following structure: synthesis macromolecule is from up to down distributed thin
Film, modified pitch self-adhesion size coat, adhesive polymer size coat.
Concrete raw material used by the most each layer all can be purchased from the market, such as, synthesize macromolecule
Thin film can be TPO thin film (polyethylene, polypropylene, polrvinyl chloride, polyvinyl acetate
Etc.), synthetic rubber thin film (EPDM, chlorosulfonated polyethylene etc.), the present invention is to modification
Colophonium self-adhesion size coat, adhesive polymer size coat are not particularly limited, domestic common factory
The product of this type of label that family produces may be applicable to the present invention.
