Description
Technical field
The present invention relates to dermatine technical field, more particularly to a kind of nano-bamboo carbon PU synthesis of artificial leather and its manufacture
Method.
Background technology
Because the genuine leather fabric common people of costliness can not consume, in response to the market demand, the artificial leather of counterfeit corium is gradually popular
Get up, be widely used in clothing, system bag.In China, it is accustomed to be that the artificial leather that raw material produces is referred to as PVC people with polyvinyl chloride resin
Fabricate-leather (abbreviation artificial leather), artificial leather is using polyvinyl chloride as coating material, using conventional fabrics as base fabric；With PU resins and non-woven fabrics
Artificial leather for raw material production is referred to as PU synthetic leather (abbreviation synthetic leather), and synthetic leather is using polyurethane resin as coating material, with non-
Woven cloths are base fabric.Also there is composite artificial leather (synthesis of artificial leather) in the market, i.e., by PVC and PU interworkings, or PVC, PU points
It is not modified with other materials interworking, so as to obtain the artificial leather with a performance requirement.The development experience of artificial leather
Three generation products, it is PVC (polyvinyl chloride) artificial leather, PU (polyurethane) artificial leather, superfine fibre artificial leather respectively.
Bamboo charcoal nano is by nanometer light catalyst material TiO with advanced technology2Load to the large, medium and small hole of bamboo charcoal
On gap wall and bamboo charcoal surface, make bamboo charcoal and photocatalyst material TiO2Perfect adaptation, thus the strong adsorptivity with bamboo charcoal matter, together
When also there is the performance of nano photocatalyst catalytic material, the organic substance of absorption, can be passed through ammonia, formaldehyde, phenol in such as air
TiO2In the presence of light, the OH that discharges-Ionization, it is decomposed into water and CO2, additionally with by virus, bacterium cell
Film and cytoplasmic protein denaturation and kill, thus with powerful adsorptivity, detoxicating, deodorization, purification and kill cause of disease it is micro-
Biological agent, it can be widely applied among industrial and agricultural production and environmental improvement, house life.
A kind of making side of bamboo charcoal nano PU synthesis of artificial leathers is disclosed in Publication No. CN104499300A file
Method, the production technology combined using Nano grade bamboo charcoal powder and artificial leather, obtains certain performance boost.But it is simply accomplished
Simply it is combined, many defects is present in the preparation of the raw material of artificial leather and bamboo charcoal, can not obtain more preferable Leather Properties,
Need improvement badly.
