According to the internal EVA enhanced waterproof board, the warp-direction enhancement layer and the weft-direction enhancement layer which are parallel to each other are additionally arranged in an EVA waterproof layer, the high breathability and the elastic property of an existing EVA waterproof board are maintained, meanwhile the mechanical property of the EVA waterproof board is remarkably improved, the environmental stress crack resistance and the shock resistance property of the EVA waterproof board are greatly enhanced, and the internal EVA enhanced waterproof board is suitable for soil engineering water resistance on multiple occasions.
Description
Technical field
The utility model relates to waterproof roll field, specifically, relates to enhancing splash guard in a kind of EVA.
Background technology
Splash guard is again geomembrane, traditionally thickness is more than or equal to geomembrane that 0.8mm is thick splash guard, be less than 0.8mm thick be geomembrane, it is a kind of impervious material of making taking high molecular polymer as base stock, is divided into homogeneous splash guard and compound water-proof.The major function of splash guard makes to prevent the seepage of liquid and the volatilization of gas, and the effect of splash guard in rock engineering is mainly the anti-isolation that blends, but also plays the effect of strengthening and protecting simultaneously.It is mainly used in: antiseepage, subway, basement and the tunnel anti-leakage lining of the engineerings such as earth and rockfill dam, rock-fill dams, stone masonry dam, concrete dam, tailing dam, sewage reservoir dam, channel, liquid storage pool, the antiseepage of road and rail ground, in sanitary garbage landfill yard, the earth working material such as tie filament geotextiles, GCL uses etc.Existing splash guard primary raw material has the materials such as low density polyethylene, LLDPE LLDPE, high density polyethylene, ethylene/vinyl acetate copolymer EVA, polyvinylchloride.
EVA class splash guard is good compared with the elasticity of PE class material, flexibility, gas permeability performance, and it has good resistance to low temperature, its heat decomposition temperature is lower, is about 230 DEG C of left and right, but its chemical-resistant resistance, oil resistivity aspect are than PE, PVC is slightly poor, and with the increase of vinyl acetate content in EVA material, changing more obviously, mechanical property obviously declines, impact resistance is lower, thereby use is subject to certain limitation.
Utility model content
The purpose of this utility model is to overcome the weak point of above-mentioned conventional art, provides that a kind of mechanical property is good, strengthens splash guard in the EVA of tear-proof, stretch-proof.
The technical solution of the utility model is:
In EVA, strengthen splash guard, it is characterized in that: comprise warp-wise enhancement layer and broadwise enhancement layer, between described warp-wise enhancement layer and broadwise enhancement layer, be provided with EVA hot melt adhesive layer, the top of the below of described warp-wise enhancement layer and broadwise enhancement layer is provided with EVA waterproof layer, polypropylene filament yarn or filament of glass fiber that described warp-wise enhancement layer is distributed by several warp-wises form, and polypropylene filament yarn or filament of glass fiber that described broadwise enhancement layer is distributed by several broadwises form.
Warp-wise long filament group and broadwise long filament group are parallel to each other, crosspoint is not bending, can be comprehensively evenly synchronous, bear external force, dispersive stress, when manufacture, brush EVA PUR, when composite sheet material, heat, warp-wise enhancement layer and broadwise enhancement layer are simultaneously hot sticky, convenient quick, splash guard radially all has great tensile strength with broadwise, there is good stability, much larger than common folder muscle or common non-woven fabric, EVA hot melt adhesive layer is close with the material of EVA waterproof layer own simultaneously, together with several holes of forming by warp-wise enhancement layer and broadwise enhancement layer are hot sticky, itself can not produce huge stress because material mechanical performance has big difference, thereby cause the problems such as bubbling, and through braiding to polypropylene filament yarn or filament of glass fiber there is good strainability and permeability, thereby can not reduce EVA waterproof material itself good elasticity and permeability.
A kind of concrete prioritization scheme, the outside of both sides EVA waterproof layer is respectively equipped with geotechnological layer of cloth.Adhesive force and scratch-resistant performance that geotechnological layer of cloth can strengthen EVA splash guard are set, and protection EVA splash guard outside, increase the service life, can as required, arrange in one or both sides.
A kind of concrete prioritization scheme, the EVA waterproof layer outside that is positioned at below is provided with geotechnological layer of cloth.
The utility model increases the warp-wise enhancement layer and the broadwise enhancement layer that are parallel to each other in EVA waterproof layer, in keeping former EVA splash guard highly-breathable, elastic performance, significantly improve the mechanical property of EVA splash guard, its environmental stress crack resistance, shock resistance strengthen greatly, are applicable to the geotechnological waterproof of multiple occasion.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
