Abstract
The utility model provides an ethylene-vinyl acetate copolymer back-stick type water stopper, which relates to the technical field of waterproof materials. One surface of the water stopper is planar, and water stop fixing ribs are arranged on the other surface of the water stopper. The water stopper effectively solves the problems existing in the prior art in long term, and has the advantages of simple and unique structure, convenient utilization, fine performance in water stopping, water proofing, seepage prevention and deformation prevention, high strength, particularly high tearing strength, corrosion resistance, acid and alkali resistance, ageing resistance, low cost, durability, fine production manufacturability, high efficiency and capability of achieving no pollution in production process. The back-stick type water stopper can be used as an auxiliary material of a waterproof plate to be widely applied to water proofing of a project of a basement, a subway tunnel, a road and a railway tunnel, and water proofing and seepage prevention of projects such as a dam, an artificial lake, a pond, a sewage treatment field, a waste landfill site and the like and can also be independently used as a water stopper to be applied to foundation projects by being arranged into deformation gaps and construction gaps in concrete pouring in site to be integrated with concrete structures so as to solve the problem of water seepage at gap positions.
Description
Technical field
The utility model relates to the waterproofing materials technical field.
Background technology
Waterproofing materials and the back sticking type waterstop of selling on the market all is that main raw material(s) is made with rubber now, rubber processing process complexity, production efficiency is low, the cost height, and, caused the ageing resistace of rubber product poor owing to have many double bond structures in the macromolecule of rubber.Sealing, waterproof, antiseep, anti-deformation and intensity difference, the life-span is short.Ethylene-vinyl acetate copolymer (being the EVA resin), unparalleled key in the molecule, ageing resistance power is strong.But there is not the low back sticking type waterstop of ethylene-vinyl acetate copolymer material and simple and practical cost at present.
The utility model content
The purpose of this utility model has provided a kind of ethylene-vinyl acetate copolymer back-pasting type waterstop, it is simple in structure, unique, easy to use, sealing, waterproof, antiseep, anti-deformation are good, intensity is the tearing strength height especially, corrosion-resistant, acid and alkali-resistance, ageing-resistant, and cost is low, durable, and production technology is good, efficient is high, can accomplish that manufacturing process is pollution-free.
Main technical schemes of the present utility model is: a kind of ethylene-vinyl acetate copolymer back-pasting type waterstop, band one side are the plane, it is characterized in that with another side be provided with sealing sealing fixing rib.
Described sealing fixing rib vertically arranges, is provided with left and right each 1 road at least, and promptly 1 pair better.
Described sealing fixing rib is provided with 4～6 roads, promptly 2～3 pairs preferable.The sealing fixing rib can be gained in strength and stagnant water effect.
The longitudinal section, top of described sealing fixing rib lacks shape, rectangle or trapezium structure for well for circle, and technology is simple; Or be structures such as oval, square, rhombus, triangle, changeable shape.Make things convenient for sealing to fix.
Described ethylene-vinyl acetate copolymer back-pasting type waterstop, it is characterized in that with cross section have identical or different thickness.
Described ethylene-vinyl acetate copolymer back-pasting type waterstop, it is characterized in that with cross section middle part thick, both sides thin, or the middle part is thick, both sides attenuation gradually.With weight reduction, be easy to welding.
Good effect of the present utility model is: contrast with prior art, solved the medium-term and long-term people that exist of prior art well wants to solve and unsolved always problem always, it is simple in structure, unique, easy to use, sealing, waterproof, antiseep, anti-deformation is good, intensity is the tearing strength height especially, because unparalleled key in the EVA molecular resin, ageing resistance power strong corrosion resistant, acid and alkali-resistance, ageing-resistant, durable, cost is low, and the EVA resin is a kind of thermal plastic high polymer material, process can adopt and directly add hot-extrudable one-time formed method, and production technology is good, the efficient height, can accomplish that manufacturing process is pollution-free.This back sticking type waterstop can be widely used in the waterproof of basement, subway tunnel, highway and railway tunnel work as the auxilliary material of splash guard, dam, artificial lake, pond, sewage-farm, draws the waterproof and the antiseepage of engineerings such as rubbish landfill site.In addition, also can use as waterstop separately, in the Foundation Design that becomes one with concrete structure in deformation joint, the constuction joint when being applied to concrete cast-in-situ, the leakage problem at the place, slit that determines.Its intensity especially tearing strength is significantly improved, and sees the following form.
EVA refers to the utility model in the table, and PVC refers to the igelite waterstop.
Be described further below in conjunction with drawings and Examples, but not as to qualification of the present utility model.

Among the figure, each label implication is: 1, ethylene-vinyl acetate copolymer (EVA) back sticking type waterstop main body, 2, the sealing fixing rib.
The specific embodiment
Referring to Fig. 1, this ethylene-vinyl acetate copolymer back-pasting type waterstop, the band one side is the plane, it is characterized in that being with another side to be provided with sealing fixing rib 2, sealing fixing rib 2 cross sections are rectangle, the top can be (with respect to the sealing fixing rib 2) circle of giving prominence to, or ellipse, square, rectangle, rhombus, triangle etc., strengthens fixed effect; Sealing sealing fixing rib 2 is vertically arranged; If left and right each 3 road, promptly 3 pairs, totally 6 roads.2 of ethylene-vinyl acetate copolymer (EVA) back sticking type waterstop main body 1 and sealing fixing rib, but one-shot forming monolithic construction not also can be and are the fusion weld structure.
Fig. 2～Fig. 8, the various situations that the tranverse sectional thickness of expression band and sealing fixing rib 2 are different.。
Tranverse sectional thickness is different better, is thick district between two sealing sealing fixing rib in middle part of external labeling type EVA waterstop, is the main stress district, because the power of bearing is relatively large, material is thicker; Both sides are thin districts, and material is thinner, and cost is saved in weight reduction.
This external labeling type EVA waterstop both sides are thin districts, its another effect be convenient to and other EVA waterproofing materials between fusion weld, make engineering integral waterproofing better effects if.
Above-mentioned ethylene-vinyl acetate copolymer market can be purchased, trade name " EVA resin ".
