Embodiment 1

[0019] Depend on figure 1 The super-weather-resistant composite waterproof roll material shown includes: super-weather-resistant polymer film layer 1, adhesive sealant layer 2, and its interlayer structure is: the surface layer is super-weather-resistant polymer film layer 1, and the middle layer is adhesive sealant Layer 2, the bottom layer is the isolation film layer 3, and these three layers are integrated by heat-compression bonding during the production process. The adhesive sealant layer of the waterproof membrane forms a physical adsorption and mortise and tenon action with cement and concrete through pressing force to form an interface layer with strong adhesion, waterproof, tear and puncture resistance, and chemical corrosion resistance, thus forming a firm bonding.

[0020] In this embodiment, the surface layer is a 10 μm PVDF film layer 1, the middle layer is a butyl rubber layer 2, and the bottom layer is a polyethylene film layer 3, and the three are bonded by he...

Embodiment 2

[0022] A super weather-resistant composite waterproof membrane, the surface layer is a 280μm thick PVDF / PET composite film layer 1, the middle layer is a SBR modified asphalt layer 2, and the bottom layer is a polyethylene film layer 3. The three are bonded by heat and pressure, specifically Composite method is with embodiment 1.

[0023] The PVDF / PET composite film layer is composed of PVDF and PET two-layer film by double-layer co-extrusion blown film or casting process, and the PET layer is in contact with SBR modified asphalt.

Embodiment 3

[0025] A super weather-resistant composite waterproof membrane, the surface layer is a 140μm PVDF / PE composite film layer 1, the middle layer is a butyl rubber layer 2, and the bottom layer is a polyethylene film layer 3; the PVDF / PE composite film is composed of two layers of PVDF and PE The film is composited, and the PE layer is located at the bottom layer in contact with the SBS and SBR blended modified asphalt layer 2.

[0026] The PET film layer 1, the APP modified asphalt layer 2, and the polyethylene film layer 3 are bonded by heat and pressure, and the specific composite method is the same as that in Example 1.

Abstract

The invention relates to the field of waterproof roll materials, and particularly relates to a super weather-proof composite waterproof roll material. The super weather-proof composite waterproof roll material comprises a bonding and sealing adhesive layer and an isolating film protection layer, and also comprises a super weather-proof polymeric film layer, wherein the super weather-proof polymeric film layer, the bonding and sealing adhesive layer and the isolating film protection layer are sequentially arranged from top to bottom and are adhered into a whole in a hot pressing way. The hot pressing temperature is 30 to 220 DEG C, includes but is not limited to 30 to 220 DEG C, and can be adjusted according to factors such as specific production equipment and a hot pressing technology. The bonding and sealing adhesive layer is compounded with the a super weather-proof polymeric film structure, so that the structure has high environmental resistance, corrosion resistance, high strength and high toughness, good dimensional stability, and high impact resistance and puncture resistance, does not need to be protected by cement and mortar, and can be constructed in various environments.

Description

technical field [0001] The invention relates to the field of waterproof coiled materials, in particular to a super-weather-resistant composite waterproof coiled material. Background technique [0002] With the development of society and the progress of the times, the market has higher and higher requirements for building materials, and the original building materials can no longer meet the needs of the market. At present, the surface layer of ordinary waterproof materials has limited resistance to environmental aging and corrosion resistance, resulting in problems such as low service life of waterproof membranes, unsatisfactory waterproof and wear resistance. Mortar protective layer must be used in construction to prevent puncture damage and ultraviolet damage. It cannot withstand the corrosion of acid, alkali and chlorine corrosives in water, resulting in premature leakage. Contents of the invention [0003] In order to overcome the deficiencies of the above-mentioned pr...
