The utility model relates to the technical field of waterproof coiled materials, in particular to a waterproof coiled material with no surface folds, heat preservation, heat insulation and sound insulation.
Background
In order to ensure that the waterproof coiled material has good waterproof effect and simultaneously improves the heat preservation and heat insulation effects, the metal aluminum foil with excellent durability and ageing resistance and unique sunlight reflection and ultraviolet ageing resistance is used for the existing waterproof coiled material in the prior art. The existing metal aluminum foil waterproof coiled material structure generally comprises an aluminum foil layer, an adhesive layer and a supporting structure. The metal aluminum foil waterproof coiled material is widely applied due to the high reflection coefficient of the aluminum foil and relatively good durability.
However, the metal aluminum foil waterproof coiled material in the prior art has the following defects in practical application:
1. the metal aluminum foil coiled material in the prior art is insufficient in ductility of the metal aluminum foil on the surface of the coiled material, is easy to break, cannot meet the requirement and cope with the deformation of the coiled material in the production curling process, so that the coiled material is very easy to fold after being coiled, and the fold cannot recover as before after uncoiling construction of the coiled material, so that the surface flatness of the coiled material is reduced, the appearance of the coiled material is affected, and the fold of the lap joint part of the coiled material is increased because the coiled material is deformed, so that a water channeling channel is easily formed in practical application, and finally the waterproof effect of the coiled material is invalid. And most of waterproof coiled materials with metal aluminum foils are arranged in the waterproof coiled materials, so that the characteristics of the metal aluminum foils cannot be utilized to the maximum extent.
If patent CN 102400521A is for preventing because the influence of expend with heat and contract with cold, the aluminium foil does not have ductility and fracture to influence thermal-insulated water-proof effects, disclose a compound aluminium foil face waterproofing membrane, including plane materiel, waterproof basic unit, basement membrane, the plane materiel includes the aluminium foil, on the aluminium foil, the lower surface all compound one deck polymer membrane for reinforcing mechanical properties prevents aluminium foil fracture. However, this patent does not disclose how the aluminum foil is bonded and compounded with the polymer film, so that it cannot be ensured that the waterproof coiled material thereof will not be separated from each other during use, and thus the waterproof effect will not be affected. Meanwhile, the upper surface of the aluminum foil layer of the patent is compounded with a layer of polymer film, so that the characteristics of sunlight reflection and ultraviolet aging resistance of the metal aluminum foil cannot be utilized to the maximum extent.
2. The aluminum foil of the metal aluminum foil coiled material in the prior art can only reduce the surface temperature of the coiled material through reflected light, so that the endurance time of the adhesive material is improved, but the waterproof coiled material does not have the heat preservation, heat insulation and sound insulation functions, and the waterproof coiled material and other heat preservation materials are required to be used together to achieve the purpose of heat preservation and heat insulation.
As patent CN 103818055A discloses a self-adhesive waterproof coiled material of reactive heat-insulating aluminum foil butyl rubber, the self-adhesive layer of butyl rubber can be chemically reacted with cast-in-place concrete to form a whole, and can follow the concave-convex fluctuation of the roof and the wall surface of a building to be tightly attached to the roof, so that air is completely isolated from the roof and the wall body, and the heat-insulating and energy-saving effects of the building are achieved. The patent utilizes a butyl rubber self-adhesive layer to chemically react with cast-in-situ concrete, and then an air layer is matched to form a reverse radiation heat insulation system, the construction condition is that the cast-in-situ concrete can only be subjected to the chemical reaction, namely the heat insulation performance is finished according to the carrying out completeness of the chemical reaction and the matching degree of an external air layer, most of the construction conditions in reality cannot be met, and the heat insulation system does not have a stable heat insulation function.
3. The aluminum foil coiled material in the prior art has smooth surface, and the bonding firmness between the aluminum foil coiled material and the bonding layer completely depends on the bonding performance of the bonding material, so that the coiled material is easy to laminate with the bonding layer of the coiled material in the application process, and then surface holes are generated.
As patent CN 215484123U discloses a metal aluminium foil self-adhesion waterproofing membrane, through setting up the insulating layer, can be at the in-process that metal aluminium foil self-adhesion waterproofing membrane used, according to the material characteristic of insulating layer, carry out reflection isolation to the outside heat energy of coiled material and handle for outside temperature is difficult to the inside through coiled material transmission roof, can effectually carry out dampproofing to the roof simultaneously. The patent also discloses that the insulating layer is made of metal aluminum foil material, and the insulating layer is fixedly connected with the tire body through an adhesive. Namely, the bonding firmness between the aluminum foil coiled material and the matrix completely depends on the bonding performance of the adhesive, delamination of the aluminum foil and the matrix easily occurs in the application process, and then surface holes are generated to destroy the waterproof performance of the waterproof coiled material.
Based on the above-mentioned prior art's condition, there are metal foil waterproofing membrane ductility not enough, coiled material roughness low, easy fracture, aluminium foil layer and adhesive linkage firmness are not enough, self do not have thermal-insulated sound insulation function, lead to the coiled material to appear the fold easily and scurrying the water passageway and make waterproof thermal-insulated effect discounting greatly among the prior art.
