Abstract
The utility model discloses a leather bonding structure adopting waterborne polyurethane glue and belongs to the field of leather processing bonding technology. The leather bonding structure adopting the waterborne polyurethane glue is structurally composed of a surface layer, a bonding layer and a base fabric layer, wherein the surface layer is combined with the base fabric layer through the bonding layer in a bonding mode. An external surface of the surface layer is provided with weft-knitted fabric such as napping or fluff, and irregular protrusions and wrinkles are arranged among the napping or the fluff so that good effect of leather is ensured. An external surface of the base fabric layer is provided with the fluff so at to ensure bonding reliability and softness and comfortability in use and has a function of heat preservation. The bonding layer is uniformly coated with the waterborne polyurethane glue to form an adhesive film. Compared with a structure of traditional leather, the leather bonding structure adopting the waterborne polyurethane glue is more firm, durable and not prone to crack, and has a smooth surface and better comfort effect.
Description
Technical field
The utility model relates to a kind of leather bonds structure, specifically a kind of employing aqueous polyurethane glue bond leather bonds structure.
Background technology
In recent years, domestic, along with developing rapidly and environmental requirement strict day by day of industry such as Domestic Automotive Industry, adnornment industry, garment manufacturing industry, building industry; The importance of the development of binding agent highlights gradually, it is reported, China has become the production and consumption big country of artificial leather; Family surplus enterprise reaches 2.4 ten thousand, total industrial output value reaches 21,039 hundred million yuan, and this type of composite finished product that goes out is in operating process; The spraying of glue difficulty, high, the poor heat resistance of viscosity occur, goods come unglued easily in summer or when crossing the equator and take off plate, improve hear resistance as adopting the interpolation curing agent to wait; Can increase cost on the one hand, increase one procedure on the other hand, cause the troublesome poeration activation temperature too high; For being applied in the cabinet aspect; Then show the bound edge weak effect and not too suitable, need come reinforced cementitious intensity, added behind the MDI needs and drawback such as could use through abundant stirring through adding MDI.
Emulational leather is the higher series products of class in " immersion coating leather "; So far have the history of four more than ten years; Its basic comprising is by woven base or nonwoven base; Be coated with redoubling with binding agent respectively and adopt special foaming treatment to process, have surperficial feel to exactly like corium, have characteristics such as air permeability and good, wearability, cold resistance.
Summary of the invention
In order to overcome existing leather non-watertight, airtight and to cause the deficiency of layer of cloth separation etc. owing to the binding agent performance; The purpose of the utility model: be to provide a kind of employing aqueous polyurethane glue bond leather bonds structure, have waterproof, breathe freely, do not have irregular projection, fold and the advantage that layer of cloth separates can not occur.
It is following that the utility model solves the technical scheme that its technical problem adopted:
A kind of employing aqueous polyurethane glue bond leather bonds structure, its structure mainly is made up of superficial layer, tack coat, base cloth layer, and wherein superficial layer and base cloth layer are compound through the tack coat bonding.
Described superficial layer, its outer surface is provided with the weft-knitted fabric of plucking or fine hair, and is provided with irregular projection and wrinkle in superficial layer plucking or the fine hair, has guaranteed the effect that leather is good.
Described base cloth layer, its outer surface is provided with fine hair, and flexibility, the comfortableness of the fixing that has guaranteed bonding when using has thermal effect.
Described tack coat, it adopts aqueous polyurethane glue, is coated with the back on evenly to form bonding film; Thin and have certain thickness; And have trickle through hole, the aperture of this trickle through hole is less than the diameter of hydrone and greater than the diameter of air molecule, and aqueous polyurethane glue has high-intensity bond properties.
The utility model is compared with traditional leather structure, firmer, durable, be difficult for breaking, surfacing, comfortable effect be more remarkable.
The aqueous polyurethane glue that the utility model is selected for use; All has high adhesive property for multiple skin class, dry goods etc.; And can anti-100 ℃ high temperature; The utility model can be applicable to software man decorations, the processing of furniture, manufacturings such as high-grade leather, mattress, sofa, casing, is adapted at the stickup on the absorbability base material.
Through adopting above technical scheme, the utlity model has following beneficial effect:
1, owing to adopted aqueous polyurethane glue, ensures the quality of pasting, had waterproof, ventilative, increased user's comfortableness;
2, in process, guarantee the uniformity of intermediate adhesion film, can stop the appearance of the situation such as no irregular projection, fold of cloth interlayer;
3, owing to adopted aqueous polyurethane glue, have the caking property of intensity, stopped problems such as each is prone to come off layer by layer in the leather structure, separation.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1-base cloth layer, 2-tack coat, 3-superficial layer, 4-base cloth layer fine hair, 5-superficial layer plucking or fine hair.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified, but not as the qualification to the utility model.
See also shown in Figure 1, a kind of employing aqueous polyurethane glue bond leather bonds structure, its structure mainly is made up of superficial layer 3, tack coat 2, base cloth layer 1, wherein superficial layer 3 is compound through tack coat 2 bondings with base cloth layer 1.
Described superficial layer 3, its outer surface is provided with the weft-knitted fabric of superficial layer plucking or fine hair 5, and is provided with irregular projection and wrinkle in superficial layer plucking or the fine hair 5, has guaranteed the effect that leather is good.
Described base cloth layer 1, its outer surface is provided with base cloth layer fine hair 4, and flexibility, the comfortableness of the fixing that has guaranteed bonding when using has thermal effect.
Described tack coat 2, it adopts aqueous polyurethane glue, is coated with the back on evenly to form bonding film; Thin and have certain thickness; And have trickle through hole, the aperture of this trickle through hole is less than the diameter of hydrone and greater than the diameter of air molecule, and aqueous polyurethane glue has high-intensity bond properties.
The utility model is compared with traditional leather structure, firmer, durable, be difficult for breaking, surfacing, comfortable effect be more remarkable.
The aqueous polyurethane glue that the utility model is selected for use; All has high adhesive property for multiple skin class, dry goods etc.; And can anti-100 ℃ high temperature; The utility model can be applicable to software man decorations, the processing of furniture, manufacturings such as high-grade leather, mattress, sofa, casing, is adapted at the stickup on the absorbability base material.
