Abstract
The utility model belongs to the technical field of PU (polyurethane) products, and in particular relates to PU synthetic leather for furniture. The PU synthetic leather comprises a dry-process PU leather layer and a wet-process PU leather layer, wherein a first hot melt glue layer is arranged between the back side of the dry-process PU leather layer and the front side of the wet-process PU leather layer; a second hot melt glue layer is arranged on the back side of the wet-process PU leather layer. Compared with the prior art, the PU synthetic leather for furniture has the advantages that the dry-process PU leather layer and the wet-process PU leather layer are compounded through the first hot melt glue layer, and the second hot melt glue layer is arranged on the back of the wet-process PU leather layer, so that the PU synthetic leather is good in hydrolysis resistance, abrasion resistance, toughness and elasticity, has the characteristics of large thickness, soft, plump and light hand feel, and has a nice appearance. During use, the PU synthetic leather can be applied to the field of furniture as long as the PU synthetic leather is adhered to a knitted fabric base through the second hot melt glue layer, thus being simple and convenient, and strong in applicability.
Description
Technical field
The utility model belongs to PU product technical field, relates in particular to a kind of furniture PU synthetic leather.
Background technology
PU is the abbreviation of English poly urethane, chemical Chinese " polyurethane ".PU synthetic leather is widely used in makeing the decoration of case and bag, clothes, footwear, vehicle and furniture now, and it obtains affirming of market day by day, and its range of application is wide, and quantity is big, more than kind, is that traditional natural leather cannot meet.And it has advantages of that many PVC synthetic leather can not compare, be to replace the comparatively desirable material of natural leather.
PU synthetic leather divides according to its production technology, can be divided into dry method, wet method and cohesion and slowly answer three kinds of methods, and wherein, dry method PU leather is in sense of touch, toughness and be all enough in appearance the corium that matches in excellence or beauty, and it is bonding, and firmly hydrolytic resistance is good, ABRASION RESISTANCE is high, but thickness low LCL; Wet method PU leather has good moisture-penetrable ventilated performance, and generally its thickness is larger, therefore can improve the thickness of product, make feel more plentiful, but wet method PU leather hydrolysis not, and surface is not wear-resisting, be not suitable for field of furniture, and only use dry method PU leather thickness inadequate.
In view of this, necessary a kind of furniture PU synthetic leather that provides, it is compound by the first hot melt adhesive layer by dry method PU leather layer and wet method PU leather layer, and at the back side of wet method PU leather layer, the second hot melt adhesive layer is set, make it both there is good hydrolytic resistance, ABRASION RESISTANCE, toughness and elasticity, there is again larger thickness, also there is soft, plentiful, slim and graceful feature, and appearance looks elegant; During use, only the utility model need be sticked on fabricbase and be can be used for field of furniture by the second hot melt adhesive layer, simple and convenient, applicability is strong.
Utility model content
The purpose of this utility model is: for the deficiencies in the prior art, and provide a kind of furniture PU synthetic leather, it is compound by the first hot melt adhesive layer by dry method PU leather layer and wet method PU leather layer, and at the back side of wet method PU leather layer, the second hot melt adhesive layer is set, make it both there is good hydrolytic resistance, ABRASION RESISTANCE, toughness and elasticity, there is again larger thickness, also there is soft, plentiful, slim and graceful feature, and appearance looks elegant; During use, only the utility model need be sticked on fabricbase and be can be used for field of furniture by the second hot melt adhesive layer, simple and convenient, applicability is strong.
For achieving the above object, the utility model adopts following technical scheme: a kind of furniture PU synthetic leather, comprise dry method PU leather layer and wet method PU leather layer, between the front of the back side of described dry method PU leather layer and described wet method PU leather layer, be provided with the first hot melt adhesive layer, the back side of described wet method PU leather layer is also provided with the second hot melt adhesive layer.
A kind of improvement as the utility model furniture with PU synthetic leather, described dry method PU leather layer is provided with embossing or printed layers.
A kind of improvement as the utility model furniture with PU synthetic leather, the thickness of described dry method PU leather layer is 5-20mm, the thickness of described wet method PU leather layer is 10-40mm, and the thickness of described the first hot melt adhesive layer is 1-5mm, and the thickness of described the second hot melt adhesive layer is 1-5mm.
A kind of improvement as the utility model furniture with PU synthetic leather, the thickness of described dry method PU leather layer is 7-15mm, the thickness of described wet method PU leather layer is 15-30mm, and the thickness of described the first hot melt adhesive layer is 2-4mm, and the thickness of described the second hot melt adhesive layer is 2-4mm.
A kind of improvement as the utility model furniture with PU synthetic leather, the thickness of described dry method PU leather layer is 12mm, and the thickness of described wet method PU leather layer is 22mm, and the thickness of described the first hot melt adhesive layer is 3mm, and the thickness of described the second hot melt adhesive layer is 3mm.
With respect to prior art, the utility model is compound by the first hot melt adhesive layer by dry method PU leather layer and wet method PU leather layer, and at the back side of wet method PU leather layer, the second hot melt adhesive layer is set, make it both there is good hydrolytic resistance, ABRASION RESISTANCE, toughness and elasticity, there is again larger thickness, also there is soft, plentiful, slim and graceful feature, and appearance looks elegant; The utility model fully combines the advantage of dry method PU leather and wet method PU leather, and has avoided dexterously the shortcoming of the two, and between the two by hot melt adhesive combination nonpoisonous and tasteless, environmental protection, bonding firmly, not yielding.During use, only the utility model need be sticked on knitting fabricbase and be can be used for field of furniture by the second hot melt adhesive layer, simple and convenient, applicability is strong.
Hot melt adhesive Applicable temperature scope is wherein wide, has good heat-resisting, cold resistance and acid-fast alkali-proof corrosion resistance and heat endurance, and stationarity is good, and antiskid moves, and adhesive strength is high, and heat resistance is excellent, and therefore, service life is longer.And the utility model can also be selected the hot melt adhesive of different melting points according to actual needs, can arbitrarily control its processing thickness, easy to process flexible.
