Description
Technical Field
The invention relates to the technical field of wall decoration, in particular to seamless wall cloth and a preparation process and a construction process thereof.
Background
Wall cloth (wall cloth) as one kind of wall decoration material consists of base cloth and surface grey cloth (fabric woven with crossed lines). The base fabric is divided into non-woven fabric and rubber base fabric. The seamless wall cloth is one kind of wall cloth and is a new wall cloth product developed in China in recent years. Seamless wall cloth can be according to the high design of indoor wall, can be according to the whole wall cloth of pasting of perimeter of indoor wall. The seamless wall cloth is characterized by integral construction, the wall cloth can be cut according to the perimeter of a room, the width of the wall cloth is larger than or equal to the height of the room, and one room is pasted by one piece of cloth without splicing. The adhesive tape has the functions of seamless adhesion, strong stereoscopic impression, good hand feeling, decorative effect presentation, water resistance, oil resistance, pollution prevention, dust prevention, static electricity resistance, wall crack prevention, easy management and the like.
The wall cloth is divided into two types according to different construction methods: cold glue wall cloth and hot glue wall cloth.
The cold glue wall cloth is made of glutinous rice glue, potato starch glue and the like, which are firstly coated on the surface of the wall putty layer, and then the wall cloth is laid and pasted. The following disadvantages are relatively present: glue dispensing equipment such as glue, a dispensing cylinder and the like needs to be carried, the operation can not be carried by one person, the construction is difficult in coastal wet areas, and a series of after-sale problems such as mildew, orange peel and the like can occur even in the construction.
The thermal adhesive wall cloth is also called adhesive-free wall cloth, which means that the back of the wall cloth is provided with back adhesive, the adhesive is not needed to be applied during construction, and a steam iron is used for directly adhering the wall. It is in a solid state at normal temperature, can generate physical form change under high temperature (more than 90 ℃) and air pressure to form a molten colloid, and has stronger viscosity and stability.
The method for applying the hot melt adhesive to the back surface of the wide seamless wall cloth in the current market and industry comprises the following steps: the EVA glue powder is melted at high temperature, then coated on release paper with the width of 1 meter to be rolled, and then the glue film on the release paper and the back of the wall cloth are compounded together after hot ironing and melting by utilizing hot decoction at the temperature of 80-120 ℃. The wall cloth has the following defects:
1. secondary processing is required, increasing costs.
2. The width of a traditional glue film to be hot-ironed and compounded is 1 meter, so that when the whole breadth compound glue film with the width of 2.8 meters to 3.2 meters of wall cloth is met, 2-3 overlapped glue overlapping positions must exist, and therefore when a finished product which is compounded is constructed on the upper wall, after the double-layer glue is melted by a steam iron, the glue can seep to the surface of the wall cloth due to too much glue, and the defect that glue seeps in a strip shape occurs.
3. The traditional hot ironing compounding has two compounding modes: pressing plate type and continuous composite type. The two compounding modes are that the wall cloth is manually pulled flat in a tension-free state to be compounded by hot ironing. Therefore, the adhesive strength of each point is inconsistent in the compounding process, and local hollowing and wall cloth delamination are easy to occur, so that rework is caused.
4. In the traditional hot-ironing compounding method, the hot-melt adhesive film is compounded on the back of the wall cloth after being melted at high temperature, so that in the hot-ironing process, due to the factors of temperature, time and material, the defect that the melt adhesive penetrates through the front of the wall cloth easily occurs for some wall cloth with low weft density.
