Abstract
The utility model provides a cement-based permeation-preventing clamping rib water-proof coil. The coil comprises two linear low-density polyethylene layers and is characterized in that a reinforcing layer is arranged between the two linear low-density polyethylene layers, and the lower side of the lower linear low-density polyethylene layer is provided with a polypropylene acid ester pressure-sensitive adhesive layer. The coil can be unfolded and laid without an isolating layer, isolating layer residues are avoided, the combination degree of the polypropylene acid ester pressure-sensitive adhesive layer and the cement-based surface is high, the surface particles of the polypropylene acid ester pressure-sensitive adhesive layer protrude to be permeated into the cement-based surface to be mixed with the cement-based surface, the adhesive force is high, and water-proof and permeation-preventing performance is high.
Description
Technical field
The utility model relates to waterproof roll field, specifically, relates to the impermeable folder muscle of a kind of cement based waterproof roll.
Background technology
Existing adhesive waterproof coil, in construction is used, must first be removed insolated layer materials, and then carry out next step construction before paving is on cement-based material.This has just increased certain difficulty to construction, and adhesive waterproof coil often easily occurs that insolated layer materials is difficult for removing in actual use, and insolated layer materials remains on the self-adhesive bed of material or self-adhesive bed of material adhesion such as takes off at the phenomenon.Because existing separation layer material therefor is all without the lateral reactivity with cement-based material generation chemical reaction, so insolated layer materials remains on the self-adhesive bed of material and will affect adhesive waterproof coil and cement-based material adhesive property.The self-adhesive bed of material is the critical material that strengthens adhesive waterproof coil and cement-based material adhesive strength, so self-adhesive bed of material adhesion is taken off and will be affected adhesive waterproof coil and cement-based material adhesive property.
Utility model content
The purpose of this utility model is to overcome the weak point of above-mentioned conventional art, and a kind of and impermeable folder muscle of cement based adhesive property cement based good, good seepage-proof property waterproof roll is provided.
The technical solution of the utility model is:
The impermeable folder muscle of cement based waterproof roll, comprises two-layer linear low density polyethylene layer, it is characterized in that: between two-layer linear low density polyethylene layer, be provided with enhancement layer, the linear low density polyethylene layer downside that is positioned at below is provided with polyacrylate pressure-sensitive layer.
The monomer that polyacrylate pressure-sensitive has unsaturated double-bond carries out the acrylate that Raolical polymerizable makes under catalyst action.Polyacrylate pressure-sensitive has low temperature resistant, high temperature resistant preferably, can coagulate volatile matter and mass loss rate is low, and the characteristic of overflowing without pernicious gas.
LLDPE (LLDPE), under low temperature and pressure, is closed and generates as butylene, hexene or octene copolymer by ethene and senior a alkene.The LLDPE polymer that polymerization process generates has than the narrower molecular weight distribution of general low density polyethylene (LDPE) (LDPE), has linear structure simultaneously and makes it have different rheological behaviors.There is excellent environmental stress crack resistance, anti-penetrate, the performance of shock resistance and tear-proof, can mutually bond with polyacrylate pressure-sensitive, simultaneously also easily separated, can be using the linear low density polyethylene layer of top directly as the separation layer of polyacrylate pressure-sensitive layer, when coiled material is rolled, polyacrylate pressure-sensitive layer and downside linear low density polyethylene layer stress are significantly greater than upper strata linear low density polyethylene layer, thereby be convenient to separation, residual without separation layer.
A concrete prioritization scheme, described enhancement layer is polypropylene filament yarn grid layer of cloth or filament of glass fiber grid layer of cloth.Enhancement layer is to be woven into fenestral fabric by polypropylene filament yarn fiber or filament of glass fiber, further strengthens the antiseepage water resistance of coiled material, and tear-proof, tensile strength.
A concrete prioritization scheme, described polyacrylate pressure-sensitive layer downside surface is provided with some graininess projections.Arrange that projection is convenient to polyacrylate pressure-sensitive layer and cement basal plane is better bonding, interpenetrate, strengthen coiled material adhesive force.
The utility model has adopted with upper type, has the following advantages:
Without separation layer, only coiled material need be launched to paving, residual without separation layer, polyacrylate pressure-sensitive layer and cement based basal plane conjugation are high, and its surface particles projection penetrates on cement basal plane mixes with it, and cohesive force is strong, and waterproof, seepage control performance is high.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is the structural representation of the impermeable folder muscle of a kind of cement based of the utility model waterproof roll.
In figure: 1-linear low density polyethylene layer; 2-enhancement layer; 3-polyacrylate pressure-sensitive layer; 31-projection.
The specific embodiment
Embodiment 1: as shown in Figure 1, the impermeable folder muscle of cement based waterproof roll, comprise two-layer linear low density polyethylene layer 1, between two-layer linear low density polyethylene layer 1, be provided with enhancement layer 2, linear low density polyethylene layer 1 downside that is positioned at below is provided with polyacrylate pressure-sensitive layer 3, and described polyacrylate pressure-sensitive layer 3 downside surface are provided with some graininess projections 31.
Described enhancement layer 2 is polypropylene filament yarn grid layer of cloth, can certainly be filament of glass fiber grid layer of cloth, or the direct nonwoven layer by polypropylene fiber long filament or filament of glass fiber manufacturing.
