Abstract
The utility model relates to a composite water-proof coiled material made of polyester film and nonwoven fabrics. The utility model is formed by sticking a central polyester film water-proof layer spliced with the upper surface and the lower surface of the nonwoven fabrics through the polyethylene splicing film on both sides of the polyester film water-proof layer. In order to guarantee that the polyester film and the polyethylene splicing film are fixedly spliced together and to simplify the production process, a composite structure which has a two-component polyurethane tackifier layer arranged between the polyester film and the polyethylene splicing film is adopted. The water-proof coiled material has excellent waterproofness, excellent overall technical indexes and long service life, thus satisfying the operating requirements of water-proof materials for modern constructional engineering.
Description
The utility model relates to polyester film and the non-woven fabric compounded waterproof roll that a kind of waterproof construction is used.
With the nonwoven is that the macromolecular compounded waterproof material of waterproofing course had obtained general application in the middle of surface course, polythene material were in waterproof construction.But along with construction work improving constantly to the waterproofing materials requirement, because of being that the mechanical strength of waterproof roll of main body waterproofing course is low with the polyethylene, resistance to elevated temperatures is poor, and is easily aging, life-span is short, more and more can not satisfy the high standard requirement of modern construction engineering to waterproofing materials.
The purpose of this utility model is at the problems referred to above, and a kind of mechanical strength height, heat-resisting and ageing resistace good, the polyester film of long service life and non-woven fabric compounded waterproof roll is provided, and is used to satisfy the requirement of modern construction engineering waterproof to waterproofing materials.
The technical scheme that realizes above-mentioned purpose provides a kind of and the polyester film and the non-woven fabric compounded waterproof roll that constitute bonding with the upper and lower surface course of nonwoven by the bonding film of the translateral polyethylene of middle polyester film waterproofing course.
The technical solution of the utility model also comprises: between polyester film waterproofing course and the bonding film of polyethylene the dual-component polyurethane adhesive layer is set.
This polyester film and non-woven fabric compounded waterproof roll are compared with existing polymer membranes, have following advantage:
1, because of adopting polyester film as the main body waterproofing materials, polyester film tensile strength height, flexility, barrier performance and ageing resistace is good, heat-resisting quantity is strong characteristics have been given full play to, mechanical strength, water resistance and the application life of having improved waterproof roll greatly.
2, adopt the bonding nonwoven of polyethylene film that adds tackifier, both can make waterproofing course and surperficial nonwoven layer realize strong bond, can improve the waterproof reliability of coiled material again.
3, between bonding film of polyethylene and the polyester film dual-component polyurethane adhesive layer is set, technique for sticking is simplified, help reducing the cost of production of waterproof roll.
Accompanying drawing 1 is polyester film and the non-woven fabric compounded waterproof roll cross-section structure that the polyester film waterproofing course constitutes by the bonding nonwoven surface layer of the bonding film of polyethylene;
Accompanying drawing 2 is polyester film and non-woven fabric compounded waterproof roll cross-section structures of setting up dual-component polyurethane adhesive.
The utility model is described in further detail below in conjunction with drawings and Examples:
Provide as accompanying drawing, this polyester film and non-woven fabric compounded waterproof roll have nonwoven surface layer 1 and 5 and middle polyester film waterproofing course 3, nonwoven surface layer 1 and 5 and polyester film waterproofing course 3 between be provided with the bonding film 2 of polyethylene and 4.The production of this waterproof roll can be adopted a step hot pressing composite algorithm.
When adopting Fig. 1 structure to produce waterproof roll, bonding firmly for guaranteeing polyester film and the bonding film of polyethylene, need carry out interface processing, complex treatment process, cost of production height.For realizing the simplification of waterproof roll production technology, reduce product cost, the utility model can utilize bonding adhesive bonded polyester film and the bonding film of polyethylene, it provides as accompanying drawing 2, and it is to increase dual-component polyurethane adhesive layer 6 and 7 and constitute waterproof roll between polyester film waterproofing course 3 and the bonding film 2 of polyethylene and 4.The waterproof roll of this moment adopts to stick with glue earlier and is the production method of one with nonwoven hot pressing is compound again after agent makes polyester film and polyethylene film bonding.
The surface course nonwoven of this waterproof roll can adopt polypropylene filament hot rolling nonwoven fabric and PFY hot rolling nonwoven fabric.The relative polypropylene filament hot rolling of its PFY hot rolling nonwoven fabric nonwoven fabric mechanical strength is higher, and physical property is better, but cost is higher relatively.
Claims (2)
1, a kind of polyester film and non-woven fabric compounded waterproof roll, have the upper and lower surface course of nonwoven (1) and (5), it is characterized in that described waterproof roll is bonding and constitute with the upper and lower surface course of nonwoven by the bonding film of the translateral polyethylene of middle polyester film waterproofing course (3) (2) and (4).
2, polyester film according to claim 1 and non-woven fabric compounded waterproof roll is characterized in that being provided with dual-component polyurethane adhesive layer (6) and (7) between polyester film waterproofing course (3) and the bonding film of polyethylene (2) and (4).
