Abstract
PUA ultrafine fiber simulation skin, comprise substrate layer from top to bottom, moisture absorption air-permeable layer, middle foaming layer and top finishing layer, substrate layer is made up of superfine fibre nonwoven cloth, moisture absorption air-permeable layer is made up of polyurethane resin, top finishing layer is made up of PUA, the utility model PU and PA has complementation in nature, PUA complex emulsions has had both the two advantage, have wear-resisting, corrosion-resistant and bright, the features such as soft flexible and mechanical mechanics property is good, the waterproof of leather surface after covering with paint, lacquer, colour wash, etc. can be significantly improved, grease proofing, ventilative, the function of anti-yellowing change, superfine fibre nonwoven cloth can ensure the permeability of leather, so the advantage of the existing corium of PUA ultrafine fiber simulation skin and don't contaminated environment.
Description
Technical field
The utility model relates to a kind of artificial leather shell material, is specifically related to a kind of PUA(third generation aqueous polyurethane) ultrafine fiber simulation skin.
Background technology
At present, the cost of corium is higher, in order to watch for animals, protection of the environment, the gloss of the existing corium of synthetic leather also has the softness of corium, more and more be subject to liking of people, and the leather shoes of existing some synthetic leather commercially sold, the products such as suitcase, gas permeability is bad, wear uncomfortable, although the foaming layer that adopts had adds foam hole, there is certain gas permeability, but water resistance have dropped again, so be necessary to develop a kind of artificial leather, the outward appearance of existing corium, the external advantage such as feel, there is the inherent advantage of corium again, such as, permeability is good, waterproof, the advantages such as lines effect is true to nature.
There is the defect of ABRASION RESISTANCE, resistance to water and chemical-resistant difference in single polyacrylic acid (PA) emulsion, and it has the advantages such as high, ageing-resistant, the anti-yellowing change of mechanical strength, water-tolerant, and single polyurethane (PU) emulsion also comes with some shortcomings, gloss retention as stability, white thickening property and film is poor, and therefore PA and PU has very large complementarity in performance.
Utility model content
For the problems referred to above, the utility model provides a kind of PUA ultrafine fiber simulation skin, its object is to: solve synthetic leather poor air permeability in prior art, feel is poor, the technical problem of lines weak effect.
Technical solution of the present utility model:
PUA ultrafine fiber simulation skin, comprise substrate layer, moisture absorption air-permeable layer, middle foaming layer and top finishing layer from top to bottom, described substrate layer is made up of superfine fibre nonwoven cloth, and described moisture absorption air-permeable layer is made up of polyurethane resin, and described top finishing layer is made up of PUA.
Described PUA comprises aqueous polyurethane and fluorinated acrylate.
Described middle foaming layer is polyurethane foam structure, containing abscess in its structure.
In described fluorinated acrylate, the content of fluorine is more than 8%.
Described top finishing layer surface is provided with some minute apertures.
Described polyurethane resin surface layer accounts for product gross mass and is less than 10%.
The beneficial effects of the utility model:
The utility model PU and PA has complementation in nature, PUA complex emulsions has had both the two advantage, there is the features such as wear-resisting, corrosion-resistant and bright, soft flexible and mechanical mechanics property is good, the waterproof of leather surface, the function of grease proofing, ventilative, anti-yellowing change after covering with paint, lacquer, colour wash, etc. can be significantly improved, superfine fibre nonwoven cloth can ensure the permeability of leather, so the advantage of the existing corium of PUA ultrafine fiber simulation skin and don't contaminated environment.
Accompanying drawing explanation
Fig. 1: the utility model structural principle schematic diagram.
Wherein: 1 substrate layer 2 moisture absorption air-permeable layer 3 middle foaming layer 4 top finishing layer.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described further:
As shown in Figure 1, ultrafine fiber simulation skin, comprise substrate layer 1, moisture absorption air-permeable layer 2, middle foaming layer 3 and top finishing layer 4 from top to bottom, substrate layer is made up of superfine fibre nonwoven cloth, and moisture absorption air-permeable layer is made up of polyurethane resin, wherein, middle foaming layer is polyurethane foam structure, containing abscess in its structure, top finishing layer surface is provided with some minute apertures, and polyurethane resin surface layer accounts for product gross mass and is less than 10%.Top finishing layer is made up of PUA, PUA complex emulsions is for base-material with PU resin and fluorine-containing polyacrylic acid PA resin, and take water as a class coating of medium, have do not fire, low toxicity, the advantage such as free from environmental pollution, when the mass fraction of fluorine in whole molecule segment reaches more than 8%, hydrophilic radical mass fraction reaches about 1.8, adopts the neutralization of volatile organic base, can obtain the leather top finishing agent having and lower film water absorption rate and ground surface energy.
To sum up, the utility model accomplishes the end in view.
