Problems solved by technology

Because water molecules or other compounds in the adhesive may still cause corrosion to the metal plate, and the weather resistance of the adhesive is not good, it is rarely used
The heat compounding method solves the adhesive problem, but because the PE layer in the PE kraft paper is too thin, there are also problems with weather resistance, and the kraft paper is easy to be damaged, and it is difficult to operate during construction, and there are also problems.

example 1

[0029] The method for thermally laminating a polyethylene waterproof membrane to a metal plate in the present invention is the main technical solution. Example 1: Refer to the accompanying drawings, in the figure 1. Metal coil unwinder, 2. Metal plate cleaning area, 3. Metal plate heating area, 4. Polyethylene waterproof membrane unwinder, 5. Upper pressure roller, 8. Lower pressure roller, 6, metal plate cooling zone, 7, metal coil plate winder. The metal coil unwinder 1 is used to install the metal coil and release the metal coil at a set speed. Metal plate cleaning area 2 is used to clean grease, dirt and metal dust on the metal plate, so as to enhance the adhesion between the metal plate and the polyethylene waterproof membrane. The metal plate heating zone 3 device is used to heat the metal coil. Unwinder 4 is used for installing polyethylene waterproof membrane roll. The release speed of the polyethylene waterproof film is the same as that of the metal coil. The power...

Abstract

The invention relates to a polyethylene waterproof film plate coated by metals and a manufacture method thereof. The film plate is mainly characterized in that the metals in the polyethylene waterproof film plate coated by metals are plank stuffs; the polyethylene waterproof film is composed of two or three resin films. The production method of the polyethylene waterproof film includes the following steps: cleaning a metal plate needed to be laminated; paving the polyethylene waterproof film on the surface of the metal plate, heating the metal plate or a pressure roll so as to lead the bonding layer of the polyethylene waterproof film to be melt when the metal plate is contacted with the polyethylene waterproof film; besides, pressurizing the polyethylene waterproof film by the pressure roll to lead the polyethylene waterproof film to be flatly coated on the metal plate; cooling the metal plate which finishes thermally coating the polyethylene waterproof film to obtain the finished product of the polyethylene waterproof film.

Description

technical field [0001] The invention relates to a polyethylene waterproof membrane and a metal plate to form a composite plate and a processing method thereof. Background technique [0002] Insulation materials in industrial heat and cold insulation have the problem of corroding their metal protective layers, and this problem has attracted widespread attention. Now there are two ways to solve this problem. One is to limit the content of chloride ions (corrosion source to the metal plate) in the insulation material, and the other is to add an anti-corrosion coating on the metal protective layer. Although these two methods have a certain effect, the cost is multiplied and they are not suitable for widespread adoption. [0003] There is also a method of compounding PE kraft paper on a metal plate. There are two ways to compound PE kraft paper on the metal plate. One is to use an adhesive to bond the PE kraft paper to the surface of the metal plate; the other is to compound ...
