Description
Technical field
The utility model belongs to building waterproofing technique field, more particularly, to a kind of band barrier layer EVA adhesive waterproof coils.
Background technology
In existing technology, the oil in the self-adhesive layer of EVA adhesive waterproof coils can be oozed into EVA sheet in the market
Thoroughly, EVA sheet swelling is made to cause the forfeiture of EVA sheet layer water-proof function, does not have enhancement layer at overlap edge, after overlap joint at overlap edge
It is easy to crack, entire roof waterproof system is made to lose the function of waterproof.
The content of the invention
In view of this, the utility model is directed to a kind of band barrier layer EVA adhesive waterproof coils, has ageing-resistant performance
It is good, intensity is high, elongation percentage is big, it is environmentally protective, seam peel strength is high the advantages that.
In order to achieve the above objectives, the technical solution of the utility model is realized in：
A kind of EVA adhesive waterproof coils with barrier layer, from top to bottom successively include non-woven fabrics enhancement layer, upper barrier layer,
EVA waterproof layers, lower barrier layer, self-adhering polymer modification bitumen waterproof layer, separation layer, the self-adhering polymer modification bitumen waterproof
The middle side part that layer is equipped with overlap edge is equipped with overlap edge enhancement layer.
Further, the non-woven fabrics enhancement layer is the short fine nonwoven layer of polypropylene pin thorn, and grammes per square metre is 65g/ ㎡.
Further, the upper barrier layer, lower barrier layer are seven-layer co-extrusion film, and seven-layer co-extrusion film is PE/PA/PE/PA/
PE/PA/PE7 layer structures.
Further, the EVA waterproof layers are ethylene-vinyl vinyl acetate (EVA) and polyethylene (PE) copolymer layer.
Further, the self-adhering polymer modification bitumen waterproof layer is SBS and SBR modified asphalt material layers.
Further, the separation layer applies silicon layer, thickness 0.04mm for polyethylene (PE) layer.
Further, the overlap edge enhancement layer be polyester scrim layer, width 150mm.
Further, the non-woven fabrics enhancement layer, upper barrier layer, EVA waterproof layers, lower barrier layer, self-adhering polymer are modified
Bituminous water-proof coating, separation layer, the sum of the thickness of overlap edge enhancement layer are 1.5mm.
Compared with the prior art, a kind of band barrier layer EVA adhesive waterproof coils described in the utility model have following excellent
Gesture：
(1) a kind of EVA adhesive waterproof coils with barrier layer described in the utility model due to being provided with barrier layer, are prevented
Only the low molecule oil in pitch is permeated into EVA sheet, significantly improves the materials'use service life；
(2) a kind of EVA adhesive waterproof coils with barrier layer described in the utility model, can make due to being provided with enhancement layer
The pulling force of the material is improved；
(3) a kind of EVA adhesive waterproof coils with barrier layer of the utility model, which are provided with overlap edge enhancement layer, can make material
Overlap edge at pulling force significantly improve, avoid at overlap edge crack the problem of.Since ethylene-vinyl vinyl acetate (EVA) has
There is higher elongation percentage that material can be made to disclosure satisfy that the occasion that base changes greatly, improve the security of roof waterproof system.
Description of the drawings
The attached drawing for forming the part of the utility model is used to provide a further understanding of the present invention, this practicality is new
The schematic description and description of type does not form the improper restriction to the utility model for explaining the utility model.
