Abstract
Disclosed is a polyethylene waterproof roll with a double-side self-adhesive layer. The roll is in a layer structure, and comprises a polyethylene sheet waterproof layer. Two side faces of the polyethylene sheet waterproof layer are simultaneously and sequentially connected with enhancement layers and self-adhesive waterproof layers in a bonding mode. The outer side face of each self-adhesive waterproof layer is an isolating layer, wherein the isolating layer is altogether seven layers and the seven-layer structure is firmly combined to be a whole. The self-adhesive waterproof layer is preferably a rubber asphalt self-adhesive layer. According to the polyethylene waterproof roll with the double-side self-adhesive layer, the advantages of a polyethylene polypropylene fiber waterproof roll of being high in strength, high in percentage elongation and puncture-resistant and the advantages of a self-adhesive rubber asphalt waterproof roll of being high in percentage elongation, strong in crack resistance, self-healing and the like are fully adopted. The self-adhesive rubber asphalt layers are constructed by adopting a wet laying method, and can be bonded together with a basement layer, so that the water channeling phenomenon can be effectively prevented. The construction is convenient and the construction period is shortened. The construction methods such as a fully-adhered method and the wet laying method are adopted for the construction in accordance with different project conditions.
Description
Technical field
The utility model relates to a kind of building water-proof coiled material, specifically a kind of waterproof roll that adopts self-adhesion method or the cold construction of wet shop method, has three layers of waterproofing course.
Background technology
Existing polyethylene polypropylene composite of water-proof coiled material can be used for the underground and roof waterproof construction of building, uses the cement based bonding agent bonding during owing to construction, and this bonding agent is rigid material, has the problem of zero extension.Especially seam crossing cracking occurs easily, alters the water phenomenon.Owing to alter water, once seepage occurs, breakthrough is difficult to judge, causes difficulty to reparation.
Summary of the invention
The purpose of this utility model is to solve existing polyethylene polypropylene fiber sheet to adopt the bonding existence of rigidity zero to extend, be prone to cracking, alter the water phenomenon, and when foundation deformation the problem such as easy damage, a kind of polyethylene waterproof roll with the double-sided self-adhesive layer is provided.
The at normal temperatures cold construction of self-adhesion of this coiled material, upper and lower double-sided self-adhesive layer can form one with concrete in process of setting; Form " skin-type waterproof " with concrete, greatly increased the safety of waterproofing course.
The polyethylene waterproof roll with the double-sided self-adhesive layer that the utility model provides is layer structure, polyethylene sheets waterproofing course in the middle of described layer structure comprises, two sides at the polyethylene sheets waterproofing course are bonded with enhancement layer and self-adhesion waterproofing course simultaneously successively, lateral surface at the self-adhesion waterproofing course is separation layer, amount to seven layers, seven-layer structure is fixed to be integrated.
As preferred version, described self-adhesion waterproofing course is the rubber asphalt self-adhesive layer.
Specifically, seven-layer structure is from lower to upper successively: lower separation layer, lower self-adhesive rubber asphalt waterproofing course, lower enhancement layer, polyethylene sheets waterproofing course, upper enhancement layer, upper self-adhesive rubber asphalt waterproofing course and upper separation layer.
Advantage of the present utility model and good effect:
Compared with prior art, because the utility model is provided with (being used for waterproof) double-sided self-adhesive layer, and rubber asphalt self-adhesive layer and layer of concrete can fully bond together, and forms " skin-type " waterproof, avoids seepage, greatly increases the waterproofing course life-span.The high-elongation, crack resistance that the utility model takes full advantage of high strength, high-elongation, puncture-resistant and the self-adhesive rubber asphalt waterproofing coiled material of polyethylene polypropylene fiber waterproof coiled material be strong, have the advantage such as self-healing property.The self-adhesive rubber asphalt waterproofing course adopts wet application, can with base adhesive together, effectively prevent from altering the water phenomenon.Easy construction, saving duration.Different according to project situation, can adopt the engineering method constructions such as completely sticking method, wet shop method.
Description of drawings
Fig. 1 is the utility model double-sided self-adhesive polyethylene waterproof roll layer section time figure.
Among the figure, separation layer on 1, self-adhesive rubber asphalt waterproofing course on 2, enhancement layer on 3,4 polyethylene sheets waterproofing courses, 5 times enhancement layers, 6 times self-adhesive rubber asphalt waterproofing courses, 7 times separation layers.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, polyethylene waterproof roll with the double-sided self-adhesive layer is a kind of layer structure, polyethylene sheets waterproofing course in the middle of described layer structure comprises, being bonded with successively simultaneously enhancement layer and self-adhesive layer in the two sides of polyethylene sheets waterproofing course, is separation layer at the lateral surface of self-adhesive layer, amounts to seven layers, seven-layer structure is fixed to be integrated,, described self-adhesive layer is the rubber asphalt self-adhesive layer, be adhesive linkage be again waterproofing course.Seven-layer structure is from top to bottom successively: 1, upper separation layer, 2, upper self-adhesive rubber asphalt waterproofing course, 3, upper enhancement layer, 4, the polyethylene sheets waterproofing course, 5, lower enhancement layer, 6, lower self-adhesive rubber asphalt waterproofing course and, 7, lower separation layer.
Polyethylene sheets waterproofing course 4 is the waterproof rolls that processed through one-shot forming technique by LLDPE (LLDPE) and nonwoven polypropylene fabric, and thickness is more than the 0.5mm.Have very high hot strength, elongation per unit length, tearing strength and decay resistance.
Upper self-adhesive rubber asphalt waterproofing course 2 and lower self-adhesive rubber asphalt waterproofing course 6 thickness are 0.5 ~ 1mm.This layer is suitable to completely sticking method, wet application, and efficient is high, speed is fast, and is firm with base adhesive, effectively avoids altering the water phenomenon.
Claims (2)
1. polyethylene waterproof roll with the double-sided self-adhesive layer, it is characterized in that described polyethylene waterproof roll is layer structure, polyethylene sheets waterproofing course in the middle of comprising, two sides at the polyethylene sheets waterproofing course are bonded with enhancement layer and self-adhesion waterproofing course simultaneously successively, lateral surface at the self-adhesion waterproofing course is separation layer, amount to seven layers, seven-layer structure is fixed to be integrated.
2. the polyethylene waterproof roll with the double-sided self-adhesive layer according to claim 1 is characterized in that described self-adhesion waterproofing course is the rubber asphalt layer, is the function that adhesive linkage has again waterproof.
