Problems solved by technology

[0006] (1) Secondary processing is required, and the manufacturing cost of the release paper needs to be considered;
[0007] (2) The width of the traditional adhesive film to be ironed and laminated is 1 meter, so that when the composite adhesive film meets the entire width of the wall covering with a width of 2.7 meters to 3.4 meters, there must be 2-3 overlapping glue positions. As a result, when the composite finished product is applied to the wall, after the steam iron melts the double-layer adhesive, the excessive amount of adhesive will seep into the surface of the wall covering, resulting in strip-like adhesive defects;
In this way, the bonding strength of each point will be inconsistent during the compounding process, and local hollowing and delamination with the wall covering will easily occur, resulting in rework;
[0009] (4) The traditional hot-stamping compounding method is to melt the hot-melt adhesive film at high temperature and then compound it on the back of the wall covering. Therefore, during the hot-stamping process, due to temperature, time, and material factors, for some walls with low weft density Cloth, it is easy to have the defect that the melt glue penetrates to the front of the cloth

Embodiment 1

[0038] More specifically, the steps of the preparation method of the wide-width seamless wall covering of the present application are as follows:

[0039] (1) Unwinding: Unwind the roll-shaped wide-width seamless base fabric through the first unwinding A-axis or the first unwinding B-axis arranged side by side, and through the magnetic powder tension control system under the tension of 40kg, it is made of metal The guide roller is transported to the cloth splicing machine; the above-mentioned rolled wide seamless base fabric is alternately unrolled by the first unwinding A axis and the first unwinding B axis; the width of the wide seamless base fabric is 2.7 meters;

[0040] After the fabric splicing machine, the matching step of fabric splicing is usually carried out. The specific steps are: a storage box is provided behind the fabric splicing machine, and the storage box has an inlet guide wheel. When the first unwinding of the remaining base fabric on the A axis After the l...

Abstract

The invention relates to the technical field of wall coverings, in particular to a method for preparing wide-width seamless wall coverings. The method includes the following steps: After the wide-width seamless base fabric is processed for weft adjustment, it is transferred to the coating station; the EVA rubber powder is automatically loaded, and plasticized and extruded by a screw at a temperature of 60°C-120°C. In the mould, extrude a film-shaped coating film from the knife edge of the mold to the back of the base cloth and compound it with the base cloth, and then extrude and cool the base cloth compounded with the coating film to obtain a wide-width seamless wall covering. The method is completed once, no secondary processing is required, the whole width is free of glue, and the thickness of the film is uniform.

Description

technical field [0001] The invention relates to the technical field of wall coverings, in particular to a method for preparing wide-width seamless wall coverings. Background technique [0002] Seamless wall covering is a kind of wall covering, and it is a new wall covering product developed in China in recent years. The seamless wall covering can be designed according to the height of the interior wall, and the wall covering can be pasted as a whole according to the perimeter of the interior wall. The seamless wall covering reflects the overall construction. It can be cut according to the perimeter of the room. The width of the wall covering is greater than or equal to the height of the room. A room is pasted with a piece of cloth without splicing. Seamless paste, strong three-dimensional effect, good hand feeling, decorative effect presentation, waterproof, oil-proof, anti-fouling, dust-proof, anti-static, anti-wall cracking, easy-care and other functions. [0003] Hot-me...
