Multiple film coating construction process

Abstract

A new compound film coating construction technology. Background Art Only pasting the laminating material on the decorative base surface, air, moisture or dust are easy to invade the adhesive layer, prompting the premature aging of the laminating material and the adhesive layer, causing the laminating material to shrink, pry, and empty. The drum or the whole peels off, affecting the decorative effect. On the basis of the background technology, the present invention selects an ultra-thin composite film material with a thickness of 0.01-0.5mm to cover the decoration base surface, and then applies a finishing paint on the composite film material. The self-expansion and contraction force of the ultra-thin lamination film is small, and the adhesion of the primer is enough to resist the expansion and contraction of the ultra-thin lamination film, so that it can be integrated with the decorative base surface. It is difficult for dust to invade the adhesive layer, which eliminates the possibility of premature aging of the lamination material and the adhesive layer, and overcomes the defects of shrinkage, prying, hollowing or overall peeling off of the lamination material. The invention is particularly suitable for use in the technical field of building decoration construction.

Description

technical field [0001] The invention relates to a new construction technique of a composite film coating, which belongs to the technical field of building decoration construction. Background technique [0002] With the development of the economy, the further improvement of people's lives and the strengthening of environmental awareness, traditional decorations such as marble and veneer tiles have been greatly impacted by paint and paint decoration. Laminated film (laminated film board, plastic laminated film, wallpaper, wall covering, paper, etc.) decoration has also been widely used in construction, furniture and decoration industries. In the background technology, there is a kind of laminating construction technology suitable for on-site construction. Its process steps include: firstly treat the decorative base surface; coat the primer on the decorative base surface, that is, adhesive, or apply the adhesive Then paste the compound film material on th...

Problems solved by technology

The disadvantage of the background technology is that air, moisture or dust are easy to invade the adhesive layer, which promotes the premature aging of the laminating material and the adhesive layer, causing the laminating material to shrink, pry, hollow or peel off as a whole, and give the decorative surface a irreparable defects, which seriously affect the decoration effect and bring negative effects to the large-scale promotion and application of this process

[0003] The reasons for the above adverse phenomena are that no protective layer is applied after lamination and the thickness of the lamination material is too thick. The expansion and contraction of the lamination material and the decorative base surface are inconsistent. Hollowing or prying at the corners, or even peeling off as a whole
