Technical field
The present invention relates to organosilicon and leather manufacture technical field, and in particular to a kind of silicon rubber leather of good air permeability
And the coating process of the silicon rubber leather of the good air permeability.
Background technology
Since animal's leather has nature pore in itself, so animal's leather has natural fine air permeability and the moisture absorption
Property, it is comfortable and easy to wear, but because of animal's leather resource scarcity, of high cost, do not meet needed for masses.
Thus synthetic leather comes into being, by use for synthetic leather in the articles for daily use such as manufacture men and women's clothes, luggage and shoes and hats, but people
Find in use, fur clothing, chaparajos, leather shoes, fur cap are poor in terms of permeability made of synthetic leather, so wet
The gas of heat can not discharge between human body and clothing in time, can cause sense of discomfort.At present, in order to realize good gas permeability
Can, the method mainly taken is that leather body layer is provided with multiple minor diameter ventholes, for example, Publication No. CN
The Chinese invention patent of 203188024U, the patent of invention are embedded equipped with miniature between abrasion performance layer and urethane resin layer
Stomata, while the wearability and water proofing property of leather in itself is effectively ensured, and can by microporous treatment technology, realize leather layer it
Between form multiple micro ventilation holes, to solve the permeability of synthetic leather, but this mode production cost is higher.
Silicon rubber strand is alternately made of silicon atom and oxygen atom, is a kind of to have inorganic and organic nature macromolecule concurrently

Product, its in terms of gas permeability considerably beyond PU synthetic leather, but also not up to gas permeability as animal's leather.It is public
The number of opening is the Chinese invention patent of CN 107268282A, a kind of preparation method of moisture-penetrable ventilated silica gel synthetic leather is disclosed, in silicon
Densely covered micropore is processed on glued finished leather, obtains preferable moisture-penetrable ventilated performance.This processing method is realized with PU synthetic leather
Breathable manner is consistent, but the tearing strength of silicon rubber is only the half of PU synthetic leather, if being processed in silastic surface densely covered
Micropore, will occur that leather surface tears phenomenon during the use of silicon rubber synthetic leather, and reduce the use of silicon rubber leather
Service life.
