Abstract
The invention discloses a waterproof roll. The central part of the roll is even in thickness; the edge parts on the two sides of the roll are gradually reduced in thickness from inside to outside. The waterproof roll, applied to building operations, is capable of resisting the periphery shrinkage and warping due to the factors such as natural ageing, and therefore, the ageing damage of a lapping belt of the waterproof layer of the roll in the natural environment can be reduced to the utmost extent and the safety guarantee is provided for engineering-waterproof work.
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 field.
Background technology
Along with the scarcity day by day of natural resources, the material economy in civil construction project field comes into one's own day by day.As engineering waterproofing must waterproof roll, effectively can prevent the percolating water phenomenon of civil construction project, especially for service life longer building engineering waterproofing significant.
But the application of waterproof roll also faces problems, a wherein more serious problem is that the aging performance that cause of waterproof roll in construction and use procedure reduces and breakage.Throw off because coiled material self deterioration under the environment such as long-term illumination, air, rainwater makes lap belt region warpage be separated, make its waterproof coverage rate imperfect, cause the situations such as the local of building surface leaks, infiltration to occur 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 is the material composition improving waterproof roll, by adding anti-aging materials in the feed, that oxidation resistant material delays coiled material is aging, or directly adds low orientation glass to improve that resist warping performance of material itself.But this mode needs to improve the raw material composition of coiled material, product processes also will be caused thus more complicated, thus improve production and the use cost of product, and be unfavorable for saving waterproof material and natural resources; Another kind of mode is the thickness directly increasing waterproof roll, and this mode is without the need to changing production line and construction technology, but this kind of solution is a kind of provisional solution, and the lap belt region warpage that really cannot overcome coiled material is separated disengagement problem.
From above-mentioned, still there are the needs improving coiled material performance and reduce coiled material cost in this area.
Summary of the invention
Applicant is in long-term production, construction and research process, the warpage in the overlapping edges region after to how preventing coiled material constructing is separated and conducts in-depth research, and under the prerequisite not changing coiled material composition and thickness etc., the structure of coiled material is improved, thus the lap belt warpage that the lap belt effectively eliminating coiled material causes because of natural aging factor is separated the risk of throwing off, and improves the security of water-proof system.
Specifically, the present invention is achieved through the following technical solutions:
Waterproof roll, the middle body thickness of coiled material is even, and the marginal portion of coiled material both sides from inside to outside thickness reduces gradually.
Above-mentioned alleged thickness from inside to outside reduces gradually and covers two aspects, and be the outward flange the closer to coiled material on the one hand, the thickness of coiled material is lower; Another aspect is the reduction of thickness is unidirectional, that is reduces at thickness the situation that region does not exist projection.
When constructing, coiled material and adjacent web marginal portion are bonded together.Because the thickness reduced gradually can weaken warpage shrinkage stress effectively, even if coil edge occurs that aging causing shrinks warping stress, because bond stress is much larger than shrinkage stress, also there will not be the problem being separated and throwing off, thus add the security of use.
In the present invention, the degree reduced for thickness does not do particular determination, consider to maximize and reduce shrinkage stress, preferred fringe region meets following geometric relationship: the lateral length b in the edge thickness reduction region of coiled material both sides is not less than the thickness h of coiled material middle body, and edge thickness reduces longitudinal height reduction h in region
1be not less than 2/3 of the thickness h of coiled material middle body.
For the ease of construction, the varied in thickness in the edge thickness reduction region of coiled material both sides is smooth curved surface (comprising the special circumstances for facing directly).
Further, on the basis of the above, the concrete mode that applicants studied brim-portion thickness reduction, on the impact of receiving opposing contracting warpage issues, finds that following mode is preferred: the lateral length x that edge thickness reduction longitudinal height reduction y in region of one end and the edge thickness of coiled material both sides reduce region meets following functional relation: y=kx
n, k be greater than 0 real number, n be more than or equal to 1 real number; The other end is symmetrical with it.
In above-mentioned restriction relation, x represents that on curved surface, any point is to the horizontal range of height reduction starting position, and y represents that on curved surface, corresponding points are to the vertical range of middle body top edge.In the case, the horizontal range of the perigee distance thickness reduction starting position, region of marginal portion curved surface is b, and it is h1 that corresponding thickness reduces distance.
In these cases, the shape of coil edge shows as recessed.Because this kind of geometric surface the most effectively can resist contraction and warpage (surface tension that geometry causes is contrary with the direction of convergent force) on mechanics, thus effectively overcome the appearance of shrinking warping phenomenon, combine the bond area with adjacent web overlapping edges region simultaneously, better avoid coil edge and be separated the problem of throwing off, ensure that the security of use.
In the present invention, do not limit the bonding mode of adjacent waterproof roll overlapping regions, include but not limited to use the lap belt of bonded adhesives bonding coiled material, use jointing tape the bonding lap belt of coiled material, the lap belt etc. of the bonding coiled material of self-adhesive.
As mentioned above, the present invention improves by geometry to solve relevant technical problem, therefore the present invention does not limit waterproof roll and which kind of is specially, on market, existing coiled material product is all applicable to technical scheme of the present invention, includes but not limited to the coiled material that the coiled material of single material, two-layer different material produced with combination become or more multi-layered coiled material; Preferably, coiled material of the present invention is the three-layer type membrane waterproofing coiled material of following structure: be from up to down distributed with synthesis macromolecule membrane, modified pitch self-adhesion size coat, adhesive polymer size coat.
The concrete raw material that wherein each layer is used all can be purchased from the market, such as synthesizing macromolecule membrane can be TPO film (polyethylene, polypropylene, polyvinyl chloride, polyvinyl acetate etc.), synthetic rubber film (EPDM, chlorosulfonated polyethylene etc.), the present invention is not particularly limited modified pitch self-adhesion size coat, adhesive polymer size coat, and the product of this type of label of domestic common manufacturer production is all applicable to the present invention.
