Problems solved by technology

It is almost the same as the aluminum foil cladding coil currently used in construction, and cannot be widely used
How to keep the characteristics of the PVP light plane in the atmosphere for a long time, and use it on the roof of the building is a problem that has not been well resolved, especially the application of the anti-radiation film PVP in the waterproof membrane, which has not yet been seen. arrive

example 1

[0010] Surface treatment of PVC film with a thickness of 50μm * ;

[0011] Put the surface-treated PVC substrate in the equipment, under the vacuum degree of 0.5-0.8Pa and 80℃, first use the 3mm thick aluminum-nickel alloy containing 90% of aluminum and 10% of nickel. Aluminum from Jiangxi Province Coated with a layer of 3μm alloy film on the surface of the PVC as the target material: then use a glue applicator to coat the surface of the alloy film-a layer of anticorrosive transparent adhesive acrylate BS-3 type, Shanghai resin Factory produced) The coating thickness is 6μm, after 24 hours of curing, it is placed in the above vacuum coating machine at 0.6-1Pa and 60℃, with 3mm thick zinc oxide (99.99% purchased from Shanghai Special Metal Material Factory) as the target material A layer of 8μm thick zinc oxide mask is coated on the surface of the adhesive and processed into a radiation-resistant multilayer film PVP.

[0012] In the production line of bituminous waterproofing membr...

example 2

[0015] The method steps are the same as in Example 1, except that the surface-treated PVC is coated with a 3mm thick titanium nitride (99.99%, produced by North China Titanium Gold Company) at 0.2-0.5pa and 50°C as the target material. A 6μm titanium nitride surface layer is processed into a radiation-resistant composite film PVP, and then processed with SBS modified bitumen waterproofing membrane into a radiation-resistant PVP waterproof membrane with decorative functions.

Abstract

A radiation-resistant waterproof coiled material and its preparation method, which is made of two or more kinds of metals or alloys and metal oxides, which are coated on the PVC film twice or anti-radiation multi-layer film PVP or coated with metal compounds on the PVC film. The anti-radiation composite membrane is made by compounding the waterproof membrane of SBS modified asphalt. It has the characteristics of anti-radiation, anti-oxidation and atmospheric corrosion resistance, and its excellent reflection and heat insulation effects are better than the current waterproof membrane. The utility model integrates functions of waterproofing, heat insulation, heat preservation and decoration, has long service life, low production cost, easy control method, fast and simple construction, and has broad application prospects.

Description

Technical field [0001] The invention relates to materials in the construction field, in particular to radiation-resistant PVP composite waterproof roofing coils. Background technique [0002] At present, the best heat insulation material used in construction, aluminum foil cladding coil, has good reflection ability for short-wave radiation, mainly visible light), but the reflection ability for long-wave radiation is similar to that of a black surface. Using PVC as the base material, the PVP aluminum composite film coated with aluminum on its surface has greater reflectivity to various wavelengths of heat radiation, and the longer the wavelength, the longer the reflectivity; currently more industrially used for ceramics The heat preservation and energy saving of the kiln is limited to indoor use, but as an outdoor material, the surface of the aluminum composite film is susceptible to atmospheric oxidation and loses its metallic luster and reflective heat insulation effect. It is a...
