Description
Technical field
The present invention relates to base material field, more particularly to a kind of bamboo Charcoal Adsorption environment-friendly water-based polyurethane base material.
Background technology
Decorative material for internal wall species on domestic market is various, wherein using the wallpaper wall cloth of barbola work construction because of decoration
Property gradually substitution coating strong, easy for construction turn into the first choice of people, but common wallpaper, because using non-woven paper as base material, surface only applies
One layer of PVC material of cloth, has grown that easy alice is mouldy, cracking degumming the time, and common wall cloth easily becomes then because making fabric using fabric
Shape and it is stained, service life is short, is not suitable for the big place of the flows of the people such as hotel.Thus it is badly in need of a kind of environmentally friendly long lifespan, every
Audio fruit is good, the base material of exquisite appearance.
Synthetic Leather have gloss it is soft, naturally, soft, the strong outward appearance of kishke feel, have and substrate bonding
Excellent performance, wear-resistant, flex endurant, the excellent mechanical performance such as anti-aging, resistance to fungi is good, at the same be also equipped with cold resistance it is good,
Ventilative, washable, easy to process, the advantages that price is excellent honest and clean, it is the ideal substitute of natural substrates, is widely used in taking
The industries such as dress, shoemaking, case and bag, furniture, physical culture.
The production method of wet polyurethane synthetic leather be will be added in polyurethane wet resin DMF solvent and other fillers,
Mixed liquor is made in auxiliary agent, after vacuum machine deaeration, dipping or coated on base material, being then placed in and solvent（DMF）With parent
And property, and with the incompatible water of polyurethane resin, solvent（DMF）Replaced by water, polyurethane resin gradually solidifies, so as to be formed
Porous epithelium, i.e. microvoid polyurethane grain layer, traditionally referred to as bass (English BASS transliteration), its connotation are base materials (half
Resultant Leather) the meaning, bass by dry method veneer or surface after ornamenting, such as surface printing, embossing, mill skin technique after,
Synthetic Leather finished product can be turned into.
Typical synthetic leather wet processing includes：To the N,N-dimethylformamide of oiliness polyurethane resin（DMF）Solution
Add middle adding assistant, slurry is made, by impregnating slurry or coated on base material, then by the 25% DMF aqueous solution wash admittedly
Change, then by hot wash, processing is then dried by baking oven, so as to form with loose structure, flexible and flesh
Product-bass of skin sense.Its principle is：Contain a large amount of DMF in oiliness Polyurethane resin slurry, DMF has extremely strong hydrophilic
Property, the DMF in slurry is replaced under hygrometric state by water, so that oiliness polyurethane resin precuring；Interior aqueous precuring
Bass forms with loose structure, flexible and skin sense bass product after drying.
At present, from the point of view of with regard to the development of synthetic leather technology, the major technology bottleneck of synthetic leather rapid industrial development is hindered
Problem has two：First, problem of environmental pollution caused by solvent-borne type production system, rough calculation, China's conventional synthesis leather industry
The demand to solvent type resin is more than 200 ten thousand tons every year, and this means that annual about 1,500,000 tons poisonous and harmful substances are waved
Send a manuscript to the compositor and be put into air, so huge discharge amount of exhaust gas, seriously pollute environment in the fabrication process and to execute-in-place people
The health of member is threatened, and particularly synthetic leather factory surrounding area is produced and had a strong impact on.Second, due to using solvent-borne type
Production system, synthesize and the residual of solvent had in leather goods, the residual of particularly solvent dimethylformamide (DMF) can surpass
Mark, it is difficult to meet the requirement of ecological synthetic leather.
Under the overall situation of current national requirements energy-saving and emission-reduction, the substitute for developing solvent borne polyurethane has been general trend of events institute
Become.Aqueous polyurethane is using water as solvent, nontoxic non-hazardous, does not produce waste water, waste gas, free from environmental pollution, is solvent borne polyurethane
Preferable alternative materials, be realize artificial leather industry environmental health metaplasia production needs.
The Chinese invention patent of inventor herein Guan Ningzhang applications（Application number CN200610053939.X, the applying date
2006.10.24）Disclose kind of environment-friendly type use for synthetic leather urethane composition and synthetic leather prepared therefrom and the system of the synthetic leather

12% function nano material.The patent replaces lignin with powdered carbon, can be absorbed in the stirring of dispensing stove harmful in dispensing
Material and gas, be advantageous to environmental protection and the health of worker.Meanwhile be combined together powdered carbon and synthesis base material, make the essence of charcoal
Function is fully played in synthetic leather.This method belongs to oiliness production technology, employs N, N- bis- in process of production
NMF（DMF）Solvent, it is unavoidable also to have brought micro DMF into synthetic leather（DMF）.
《University Of Nanchang》Master's thesis in 2011《Aqueous polyurethane acid bath cohesion film forming is probed into》Paper discloses use
Acetic acid frothed aqueous polyurethane emulsion prepares synthetic leather, but goes back document and also disclose that WPU acid baths demulsification method surface and section have
Many microcellular structures, wherein plus wood powder it is more rich relative to its microcellular structure that with the addition of wood powder, but no matter which
Kind, compared with solvent-borne type PU wet methods, microcellular structure also differs obvious, and therefore, WPU acid baths are demulsified method from theory into action
It is required for making further research.
