Description
Technical field
The present invention relates to the production method of superfine fiber chemical leather, in particular to a kind of TPO modified TPU superfine fibre synthesis
The clean preparation method of leather.
Background technique
The major product of synthetic leather industry includes artificial leather, synthetic leather and superfine fiber chemical leather, these products are all moulds
The institutional framework and service performance of quasi- natural leather, and can be used as the composite material of natural leather substitute.Under normal conditions, greatly
Mostly with polyurethane (PU) and polyvinyl chloride (PVC) micro porous coating, the grain layer of natural leather is simulated, is with non-woven fabrics or textile cloth
The lamina reticularis of the simulation natural leather of substrate.In common classification, it is known as artificial leather using textile cloth as substrate, with non-woven fabrics
It is known as synthetic leather for substrate, is known as superfine fiber chemical leather using superfine fiber fabric as substrate, these are widely used in production
Shoes, boots, luggage and ball etc..From the point of view of yield, the artificial conjunction of China's plastics, synthetic leather yield are from 184.82 ten thousand tons of 2009 increasings
Grow to 343.8 ten thousand tons in 2015, compound growth rate is up to 10.9%.But Environmental Protection in China requires stringenter, weight dirt in recent years
Dye synthetic leather industry development is restricted, and industry competition is increasingly fierce.From the point of view of the performance requirement of product, polyurethane (PU) and poly-
Vinyl chloride (PVC) micro porous coating is usually made of the lower layer of the surface layer and foaming that do not foam, and the surface layer not foamed can satisfy production
The requirement of the service performances such as the wear-resisting of product surface, scratch resistance, and the lower layer to foam can satisfy the soft and full feel requirement of product.
Therefore, from the technical point of view, the technology of synthetic leather coating mainly includes two aspects of surface layer technology and foaming layer technology.
Currently, generalling use solvent type PU resin dry method shifting film in superfine fiber chemical leather technical field and carrying out making face, meeting
Serious solvent contamination is caused to environment, such PU resin passes through toluene, butanone (MEK) and dimethylformamide
(DMF) etc. it is made as primary solvent with solvent polymerization method.The organic solvent that these account for entire 60% or more resin component is basic
On be all harmful substance, and caused by human body harm be various.Wherein, butanone, acetone and dimethylformamide etc.
Solvent has sizable toxic side effect.The maximum dimethylformamide of dosage in synthetic leather production, there is skin, eye mucous membranes
Strong and stimulating, when sucking high concentrations of gas, can stimulate it is pharyngeal cause nausea, often in contact with being invaded through skin, will lead to liver function
Obstacle；And the excessive above solvent of sucking breeds the next generation to women and will generate serious negative effect.Current technology hair
