Description
One. technical field
The present invention relates to leather surface coating technology field, and in particular to the covering with paint used by bibulous leather surface into
Film --- -- resin.After this resin is covered with paint, lacquer, colour wash, etc. on leather and fur products surface, leather surface will be formed it is a kind of it is soft,
The suitable coating of light, gives leather pure and fresh, beautiful sense.
Two. technical background
1. the scheme of prior art
, for fashion and attractive in appearance, great majority are all using nappa leather, the aniline that cortex is frivolous, soft for present leather wear
, used as raw material, this is leather-like due to frivolous, softness, with the sensation as silk for leather, abortive calfskin.Wear graceful elegant, U.S.
Sight is generous, firmly gets consumers in general's favor.But this leather-like water imbibition is especially strong, with traditional coating method, far from
Requirement is covered with paint, lacquer, colour wash, etc. in the beauty cleaning that these leather and fur products instantly can be met.
Traditional coating method.Film-forming resin is directly coated on into leather surface.Leather leather in tannery is carried
Negative electrical charge, in anionic state；And film-forming resin is all the anionic materials with negative electrical charge.By anion film-forming resin
Cover with paint, lacquer, colour wash, etc. on the leather with negative electrical charge, leather can not prevent the infiltration of film-forming resin.So leather just suck it is substantial amounts of it is cloudy from
Sub- film-forming resin.After dry, a very thick tunic will be formed, leather will become very hard, raw hide leather goods are lost completely
Pliability.The stronger leather of water imbibition, as the method with is covered with paint, lacquer, colour wash, etc., direct result is exactly the clothes of some leather and fur products can not
Wear again.
Cationic Finish technology is introduced again now.Will resin cation be first sprayed on leather surface (be commonly called as envelope
Bottom), then resin anion (R.A.) is sprayed on the leather of back cover again, be so in order to prevent film-forming resin from permeating toward in leather,
One layer of thin film is only formed on back cover layer, leather would not suck substantial amounts of film-forming resin and be hardened.
2. the shortcoming of prior art
Cationic Finish technology now, although prevent the infiltration of film-forming resin, but because of the resin cation of back cover layer
Very strong positive and negative charge is all carried with the moon for covering with paint, lacquer, colour wash, etc. film forming agent from resin itself.After positive and negative charge contacts with each other, the film of formation is
Harder, the pliability of raw hide leather is not reached, change the original style of raw hide leather.This is of current leather finish field
Disappearance technology.Cause the clothes of many leather and fur products into " disposable " clothes, it is impossible to which beauty cleaning is covered with paint, lacquer, colour wash, etc..
Three. the content of the invention
1. technical problem solved by the invention.
The present invention " zwitterion electric charge adjusts resin ", solve current film-forming resin makes leather be hardened during covering with paint
The problem poor with feel.Also solving yin and yang resin can not be while the difficult problem for using put together.
The zwitterion electric charge of the present invention adjusts the charge density that resin weakens zwitterion, reduces charge difference, makes into
The electric charge of film dies down.The present invention zwitterion electric charge adjust resin, cover with paint, lacquer, colour wash, etc. on leather will shape --- ----softness it is thin
Film, has reached and has softened the leather purposefully, remains original style and features of raw hide leather.
1. first, the present invention has broken the unicity of film-forming resin.The present invention is modulated with various zwitterion film-forming resins,
Mutually learn from other's strong points to offset one's weaknesses, comprehensive effect, beyond any single film-forming resin.
2. zwitterion is organically combined.Resin cation is brought in the film-forming resin of anion by auxiliary agent, the moon is made
Cation combines, and forms " the zwitterion electric charge regulation tree of a kind of new filmogen, i.e. my invention
Fat ".
It is well known that during leather finish, two kinds of resins of negative and positive must not be mixed and be used.If being mixed in one
Rise and use, zwitterion horse back breakdown of emulsion forms block, becomes pasty state, loses validity, it is impossible to use.This is now in all teaching materials
All it is so to discuss.
And the zwitterion electric charge that I invents adjusts resin, exactly solves the problems, such as that zwitterion resin can not be together.
The present invention is, by auxiliary agent and special modulator approach, zwitterion resin to be combined, not breakdown of emulsion, is not tied
Block.Just because of the combination of zwitterion resin, the strong of the positive and negative charge that zwitterion itself is carried greatly is reduced
Degree, that is to say, that the charge density that the zwitterion electric charge of my invention is adjusted in resin is reduced.The negative and positive of my invention from
Charge of the electron adjusts resin and covers with paint, lacquer, colour wash, etc. on leather, and the film of formation would not make leather be hardened, and make cortex become very soft.It is bright
It is aobvious to feel than raw hide leather softness much, and brightness is suitable, and without modeling sense, resistance to complications, viscosity fastness strengthens, and combination property has very big
Raising.
2. the benefit that the present invention brings
1. film forming is soft, repairs and recover the leather being hardened.
The leather fur clothing that the zwitterion electric charge of every use my invention adjusts resin covering with paint is all very soft, it will be apparent that super
Go out raw hide leather, the pliability of fur clothing.Raw hide clothing is harder, touches " hitting hand ", after the zwitterion resin of my invention is covered with paint, lacquer, colour wash, etc.,
Just become very soft at once.Either domestic or import resin can not all reach this effect.
2. combination property strengthens
Except softness is outside one's consideration, other performances, such as cold resistance, viscosity fastness, water proofing property, tortuosity, light appropriateness are all much
Beyond the function that domestic and international any single resin has.
3. low cost
A kinds：Can be raw material modulation completely by domestic resin, cost greatly reduces, break from external import resin ridge
The bad phenomenon of disconnected China market.Stocked up calculating with current retail market price (Beijing retailer rather than producer stocks up)
Less than acrylic resin (18 yuan/kilogram are stocked up) 11.2%
Less than polyurethane resin (28 yuan/kilogram are stocked up) 43%
B kinds：With yuan/kilogram of external import raw material 60, modulation cost reduction by 47%
C kinds：It is that raw material modulation cost reduces by 51% with domestic and imported resin
That is
A. it is 16 yuan completely with domestic resin modulation per kilogram cost.
B. it is 31.05 yuan with import resin modulation per kilogram cost
C. closed with domestic and imported resin and adjust per kilogram cost to be 23.80 yuan
Above said that these materials were stocked up completely by retail price, well imagined if being changed to producer and stocking up, cost
Can also be greatly lowered.
3rd, environmental protection
Its not only low cost but also environmental protection, it does raw material and medium without solvent-borne type material, and water miscible covering with paint is used completely
Material and do medium with water.It is free from environmental pollution, cheap, easy to use, energy-saving material.
4. the present invention is through many experiments, and is proved that effect is very good in practice.
1.. I has individual fur specially to wash shop in Heilongjiang Province's Yichun, and the leather and fur products covered with paint, lacquer, colour wash, etc. with resin of the present invention is obtained
Unanimously approve and approve of to consumers in general.
2.. trade Co., Ltd of Tian Chengzhong Australia of Harbin City, sign a contract with me, carry out technological cooperation.
