Description
Technical field
The utility model relates to a kind of leather, and more particularly, it relates to a kind of PU leather being easy to emission of bad smell.
Background technology
Natural leather to be widely used in by people to produce commodity and industrial goods owing to having excellent natural characteristic, but along with the growth of world population, the mankind are doubled to the demand of leather, and a limited number of natural leather can not meet this demand of people already.For solving this contradiction, namely scientists begins one's study exploit person fabricate-leather, synthetic leather decades ago, to make up the deficiency of natural leather.The process that 50 years of researches historical processes are exactly artificial leather, synthetic leather is challenged to natural leather.Scientists, from the chemical composition researching and analysing natural leather and institutional framework, is set about from nitrocellulose varnished cloth, is entered into PVC artificial leather, and this is the first generation product of artificial leather.On the basis of this, done many-sided improvement and exploration, be first the improvement of base material aspect to scientist, follows by the modification of coating resin and improvement.To 20 century 70s, the outward appearance of PU synthetic leather and immanent structure and natural leather progressively close, other physical characteristics are all close to the index of natural leather, and color and luster is more more bright-coloured than natural leather; Its normal temperature folding reaches more than 1,000,000 times, and low temperature folding also can reach the level of natural leather.But PU leather has suitable peculiar smell in the early stage used usually, some allows people be difficult to accept, and easily causes the pollution of surrounding environment.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of PU leather being easy to emission of bad smell, by being provided with multiple densely covered breathable microporous on adhering layer and PU resin bed, the toxic material in PU resin and adhering layer can be allowed to volatilize fast totally.
For achieving the above object, the utility model provides following technical scheme: a kind of PU leather being easy to emission of bad smell, comprise Ji Bu, described base cloth is provided with the PU resin bed through throwing burnt process, the adhering layer for bonding is provided with between described Ji Bu and described PU resin bed, all gather in described adhering layer and described PU resin bed multiple breathable microporous, and the breathable microporous aperture in described adhering layer is 0.08 ~ 0.1mm, and the breathable microporous aperture in described PU resin bed is 0.01 ~ 0.04mm.
The utility model is set to further: described Ji Bu is staple fibre flannelette, and described Ji Bu is provided with screen cloth away from the side of adhering layer.
The utility model is set to further: described PU resin bed outer surface is coated with protective layer, and this protective layer is made up of aliphatic polymeric isocyanate.
Compared with prior art, the utility model has the advantage of, by being provided with multiple densely covered breathable microporous on adhering layer and PU resin bed, the toxic material in PU resin and adhering layer can be allowed to volatilize totally fast, and people are in the process used, have extremely excellent gas permeability equally, people have enough level of comforts in the process used.For PU resin bed through the perforation of big current micropore, more again through eleven punch 11 after adding adhering layer, guarantee that this PU removes from office gas permeability, pulling force is strong, soft bending.
Accompanying drawing explanation
Fig. 1 is the structure chart that the utility model is easy to the PU leather embodiment of emission of bad smell.
Reference numeral: 1, Ji Bu; 11, screen cloth; 2, adhering layer; 3, PU resin bed; 4, breathable microporous; 5, protective layer.
Detailed description of the invention
With reference to Fig. 1, the PU leather embodiment that the utility model is easy to emission of bad smell is described further.
A kind of PU leather being easy to emission of bad smell, comprise base cloth 11, described base cloth 11 is provided with the PU resin bed 33 through throwing burnt process, the adhering layer 22 for bonding is provided with between described base cloth 11 and described PU resin bed 33, adhering layer 22 is made up of colloid, that can guarantee PU stable resin is fixed on base cloth 11, and its laying depth is 0.25mm.
Described adhering layer 22 and all densely covered multiple breathable microporous 44 in described PU resin bed 33, breathable microporous 44 aperture in described adhering layer 22 is 0.08 ~ 0.1mm, and breathable microporous 44 aperture in described PU resin bed 33 is 0.01 ~ 0.04mm.The breathable microporous 44 in this aperture substantially be can't see in the naked eyes of ordinary person, PU resin is not destroyed substantially itself, and aperture in adhering layer 22 is relatively large, this makes it possible to guarantee that the permeability in adhering layer 22 is better than PU resin bed 33, ensures distributing of volatile noxious material.
By being provided with multiple densely covered breathable microporous 44 on adhering layer 22 with PU resin bed 33, the toxic material in PU resin and adhering layer 22 can be allowed to volatilize totally fast, and people are in the process used, have extremely excellent gas permeability equally, people have enough level of comforts in the process used.
Wherein, described base cloth 11 is staple fibre flannelette, and described base cloth 11 is provided with screen cloth 1111 away from the side of adhering layer 22.Staple fibre flannelette uses in body sense comparatively comfortable in life, and coordinate the structure of screen cloth 1111 to play the effect of protection staple fibre flannelette, staple fibre flannelette also has enough gas permeabilities simultaneously, facilitates the gas of leather inside to shed.
Wherein, described PU resin bed 33 outer surface is coated with protective layer 55, and this protective layer 55 is made up of aliphatic polymeric isocyanate.This aliphatic polymeric isocyanate is mainly by poly-hexanedioic acid ethylene glycol-1,4-butanediol ester glycol (PE2BA), isophorone diisocyanate (IPDI), isophorone diamine (IPDA), toluene, isopropyl alcohol, titanium dioxide, L-770(ultra-violet absorber), BHT(antioxidant), BYK-358(levelling agent), CERMAT-237(delustering agent) make, its excellent performance, not only tough and hard wear resistant, resistance to chemical attack, and pliability is good, be easily attached to various ground.Use aliphatic polymeric isocyanate, PU resin is had the following advantages: protect light, not yellowing, resistance to chemical attack, attractive in appearance, protection, durable.
The above is only preferred embodiment of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
