Abstract

The invention discloses non-woven embossed wallpaper which solves the problems that a foaming layer of the traditional wallpaper is thin easily falls off from a printing layer. The non-woven embossed wallpaper is characterized by being made by adopting a secondary foaming process, namely, a PVC (Polyvinyl Chloride) coating is coated on the surface of fiber non-woven paper to carry out primary foaming, an inhibitor is used for inhibiting, so that an area on which the inhibitor is coated cannot be foamed due to high temperature, and therefore a required wallpaper pattern is obtained; and a PVC sizing agent is used for carrying out secondary foaming, so that the product of which the foaming height can reach 0.5mm at most can be obtained. According to the non-woven embossed wallpaper, a foaming layer is thick and difficulty falls off, the stereoscopic impression is strong, the texture is soft, the sense of touch is good, the patterns are distinct, the cleaning is convenient, and non-woven embossed wallpaper can be directly scrubbed.

Description

Nonwoven embossment wallpaper

Technical field

The present invention relates to a kind of wallpaper, relate to or rather a kind of foaming wallpaper.

Step 2, by the wallpaper obtaining by step 1, sends into wallpaper printing equipment, by the pattern in roller by color and pattern coining to the wallpaper having coated;

Step 3, the wallpaper that step 2 is obtained suppresses, and by a set of print roller, inhibitor mixed water color ink is printed onto on wallpaper together again, then by chill roll, utilizes recirculated water to carry out cooling, returns to normal temperature state;

Described inhibitor is BTA, and consumption is 1.5～3% of PVC coating weight described in step 1; Described water color ink consumption is 2～5% of PVC coating weight described in step 1;

Step 4, PVC slurry on the wallpaper surface that step 3 is obtained; Described PVC slurry is comprised of the component of following weight proportioning: 85～115 parts of polyvinyl chloride (PVC) paste resin, 55～75 parts, plasticizer, 2～4 parts of KZ heat stabilizers, 3～5 parts of 86D swelling agents; Utilize hot blast that slurry is dried at 170～180 ° of C;

Step 5, the wallpaper that step 4 is obtained is sent into baking oven and is heated, and temperature is 180～220 ° of C;

Step 6, the wallpaper that step 5 is obtained, by chill roll, utilizes recirculated water to carry out cooling, returns to normal temperature state, makes foamed pattern obtain cooling curing;

Step 7, the wallpaper that step 6 is obtained is tested, and qualified wallpaper is wound into the product of regular length and width; Carry out again heat shrink films packing, according to same size, pack carton into, obtain finished product wallpaper.

Described step 3 also comprises extrusion process, after inhibitor mixed water color ink is printed onto on wallpaper together, according to the colored type of design, the corresponding use of color, overlap print roller colouring more more, there will be radian with the borderline region that is not coated with inhibitor being coated with inhibitor, be similar to be extruded and form.

Described check is that range estimation wallpaper foaming has inviolateness, and whether foaming height reaches requirement, or no too high, and the qualified wallpaper of range estimation is sticked to wall, sees if there is aberration, and foaming has or not unequal phenomenon.

As shown from the above technical solution, the present invention is by the explained hereafter of second time of foaming, and foaming layer is abundant, difficult drop-off, and foaming height reaches as high as 0.5mm, generally at 0.3～0.5mm, far above existing products in markets; Fill the domestic gaps, greatly reduce product cost, inexpensive, met consumers in general's the level of consumption, fashion is graceful, environment protection health; Visual effect, the product third dimension of this technique is strong, just as embossment, has different visual effect, makes the sense that more has levels of the interior space of a sealing; Sense of touch, product skin texture is true to nature, and quality is soft, gives a kind of warmth of consumer, comfortable, and the sensation of safety has met consumer's tactile experience; Docking is convenient, and constructability, without clear gap; Be convenient to cleaning, can directly clean.
