A high weather resistance heat insulation color steel plate

Abstract

The invention relates to a high-weather-resistance heat-insulation color plate, and belongs to the technical field of building materials. The high-weather-resistance heat-insulation color plate is provided to solve the problem that the existing color plate is easy to age and drops easily. The high-weather-resistance heat-insulation color plate comprises a base plate, and an anti-corrosion film layer, an aluminum foil film layer, a first PET film layer and a modified PVDF film layer successively cover the upper surface of the base plate from inside to outside. The high-weather-resistance heat-insulation color plate is mainly prepared from the following raw materials in parts by weight: PVDF 60-90 parts, polymethyl methacrylate 10-15 parts, nano silicon dioxide 5.0-8.0 parts, polyethylene glycol 0.5-0.8 part, acrylic acid-modified alkyd resin 10-15 parts, a silane coupling agent 0.5-2.0 parts, polyethylene terephthalate 3.0-4.0 parts, acrylic acid 2.0-3.0 parts, fluorine-modified polyacrylate copolymer 2.0-4.0 parts and an ultraviolet absorber 0.5-1.0 part. The integral high-weather-resistance heat-insulation color plate has high corrosion resistance, weather resistance and acid-base resistance, and has the advantage of long service life.

Description

technical field [0001] The invention relates to a high weather-resistant heat-insulating color steel plate, which belongs to the technical field of building materials. Background technique [0002] Color steel plate is usually used as a building material, widely used in the walls of large public buildings, public factory buildings or integrated houses, etc. In summer, when the sun shines, the surface temperature of the color steel plate is as high as 60°C, and the temperature of the inner layer also reaches more than 50°C. Under such a high temperature, the indoor temperature will inevitably be very high. Storage and use have a greater impact on safety. Therefore, in the prior art, there is a composite color steel plate for improving the heat insulation effect by improving the structure of the color steel plate. The steel plate is the base plate, an aluminum foil layer is attached to the outer surface of the base plate, and a PET lamination layer is also arranged on the su...

Problems solved by technology

Although, PET itself has certain anti-corrosion and anti-aging functions; however, because the color steel plate is usually completely exposed to sunlight as a building material, the weather resistance of the PET material is relatively poor. On the other hand, especially the color steel plate When applied to wall panels or roof panels such as chemical plants, the use environment of color steel plates is relatively harsh, such as strong corrosion or humid environment, etc., especially for acid and alkali corrosion, which cannot be solved well, thereby reducing its At the same time, especially part of the composite layer is bonded together by glue, if the surface anti-ultraviolet effect is too poor, the ultraviolet rays will penetrate through the assembly to accelerate the aging of the glue layer material, resulting in problems such as the composite layer falling off, reducing the color. The overall service life of the steel plate
