Abstract
The application relates to one kind of core-enhanced polyethylene fiber waterproof roll, including polyethylene waterproof layer, enhanced layer of fiber net and non-woven layer on both sides, featured by the fact that polyethylene waterproof layer has two tiers, the enhanced layer of fiber net is located between these two tiers and the grid length and width of fiber net is 0.2-2.0cm with hollow part accounting for more than 50 percent of the total area of the grid. The application can adopt melt extruding method or secondary heating method of polyethylene film. The tensile strength of the roll is greatly enhanced through strengthening the polyethylene waterproof core layer; as the enhanced layer of fiber net is located between two tiers of polyethylene film, the composite of polyethylene and non-woven fabrics will not be affected; due to high viscosity of the extruded melting polyethylene or heated polyethylene film, the medium fiber net can be tightly coated and the composite of the two tiers of polyethylene film is also good; and other performances of the roll will not be affected.
Description
Technical field
The application relates to waterproof roll, especially polyethylene polypropylene water-proof coiled-material with reinforced inner layer.
Background technology
Polyethylene polypropylene fiber waterproof coiled material is to be that main water barrier and nonwoven polypropylene fabric are composited through heating with the polyethylene kind synthesized polymer material.It is because impervious ability is strong, corrosion-resistant, rough surface, and coefficient of friction is big, can be directly bonding in process of setting with cement, construct fairly simple and more and more be subjected to consumer's favor.Traditional polyethylene polypropylene fiber waterproof coiled material is to be formed by the non-woven fabric compounded of the polyethylene waterproof membrane of centre and two sides, but, because polyethylene polypropylene fiber waterproof coiled material thickness is less, tensile strength is less, generally about 60-70N/cm, along with country more and more is restricted its scope of application of raising of buildings waterproof quality requirement.This just needs the polyethylene polypropylene fiber waterproof coiled material of enhancement mode.
The enhancement mode polyethylene polypropylene fiber waterproof coiled material is also arranged in the market, such as strengthening polyethylene polypropylene fiber waterproof coiled material with glass fiber mesh or steel wire, this coiled material is four-layer structure (as Fig. 1), its intensity increases to a certain extent, but they all are to add the intensity that layer of glass net or steel wire increase coiled material between the polyethylene film of conventional polyethylene polypropylene fiber waterproof coiled material and nonwoven polypropylene fabric.Owing to be " cold compound " between glass fiber mesh or steel wire and the nonwoven, reduce the contact area of nonwoven and polyethylene film like this, made nonwoven and polyethylene film compound bad, be easy to peel off, caused product quality to descend.
Summary of the invention
The application's purpose is to overcome deficiency of the prior art, and a kind of tensile strength height and the good polyethylene polypropylene water-proof coiled-material with reinforced inner layer of composite effect are provided.
The application's waterproof roll is five shape structures layer by layer, it comprises the nonwoven on polyethylene waterproof layer, fleece enhancement layer and both sides, it is two-layer to it is characterized in that the polyethylene waterproof layer has, the fleece enhancement layer is positioned in the middle of the two layers of polyethylene watertight composition, the length and the width range of fleece grid are 0.2-2.0cm, the area of its hollow space should account for more than 50% of the grid gross area, to guarantee the composite effect of coiled material.
The application can adopt the production of fusion curtain coating extrusion molding, promptly extrudes two polyethylene films simultaneously with two extruders, adds one deck fleece in the middle of two polyethylene films, and is simultaneously compound with the two-layer nonwoven of ragged edge, forms five layers of composite construction.
The application also can adopt polyethylene film post bake method to produce waterproof roll, and promptly with two polyethylene films of two heater heating, fleece on therebetween gets final product with the outside two-layer nonwoven is compound.Its product structure is identical with the waterproof roll that fusion curtain coating extrusion molding is produced.
Polyethylene waterproof membrane among the application also can be other vinyl group of plastics film; The also available terylene non-woven fabric of nonwoven polypropylene fabric replaces; Fleece wherein can be glass fiber mesh, steel wire or other plastic wire.
The application's advantage is: (1) improves the tensile strength of coiled material by strengthening the polyethylene waterproof sandwich layer of polyethylene polypropylene fiber waterproof coiled material greatly, and increase rate depends on the tensile strength of selected fortifying fibre, generally can improve 20-200%.(2) the fortifying fibre network folder is in the middle of the two layers of polyethylene film, do not influence the compound of polyethylene and nonwoven, because the polyethylene film viscosity after molten polyethylene that two extruders has just been extruded or the heating is very big, what the fleece of centre can be cladded is very tight, two layers of polyethylene film compound yet very good, other performance of coiled material can not descend.
Description of drawings
Fig. 1 is the cross-section structure of existing enhancement mode polyethylene polypropylene fiber waterproof coiled material, and for the ease of narration, the fiber reinforcement among the figure is placed on (in actual production, fiber-reinforced layer also can place between watertight composition and the top layer nonwoven) between watertight composition and the bottom nonwoven; Fig. 2 is the cross-section structure of the application's polyethylene polypropylene water-proof coiled-material with reinforced inner layer.
Among the figure: 1-top layer nonwoven, 2,4-polyethylene waterproof layer, 3-fleece enhancement layer, 5-bottom nonwoven.
The specific embodiment
Fig. 1 is the cross-section structure of existing enhancement mode polyethylene polypropylene fiber waterproof coiled material, as can be seen from the figure, existing enhancement mode polyethylene polypropylene fiber waterproof coiled material is a four-layer structure, it is to add one deck fleece enhancement layer 3 between polyethylene waterproof layer 2 and lower floor's nonwoven polypropylene fabric 5, and then with top layer nonwoven 1 and bottom nonwoven 5 compound getting final product.
Fig. 2 is the cross-section structure of the application's polyethylene polypropylene water-proof coiled-material with reinforced inner layer, as can be seen from the figure, it comprises top layer nonwoven 1, bottom nonwoven 5, fleece enhancement layer 3, polyethylene waterproof layer 2 and 4, and fleece enhancement layer 3 is positioned in the middle of two layers of polyethylene watertight composition 2 and 4.
Adopt fusion curtain coating extrusion molding during production, promptly adopt two extruders to extrude two polyethylene films 2 and 4 simultaneously, in the middle of two polyethylene films 2 and 4, add one deck fleeces 3, compound with top layer nonwoven 1, bottom nonwoven 5 simultaneously, form five layers of composite construction.
Also can adopt polyethylene film post bake method, with two two polyethylene films 2 of heater heating and 4, fleece enhancement layer 3 on therebetween is with outside two-layer nonwoven 1 and 5 compound getting final product.
Claims (1)
1, a kind of polyethylene polypropylene water-proof coiled-material with reinforced inner layer, it comprises the nonwoven on polyethylene waterproof layer, fleece enhancement layer and both sides, it is two-layer to it is characterized in that the polyethylene waterproof layer has, the fleece enhancement layer is positioned in the middle of the two layers of polyethylene watertight composition, the length and the width range of fleece grid are 0.2-2.0cm, and the area of its hollow space should account for more than 50% of the grid gross area.
